The problem to be solved by the invention

The heat sink and the cover of the illuminating lamp like Patent Document 1 are formed of different materials and manufacturing processes, and therefore have different dimensional variations. Therefore, in order to securely attach the heat sink inside the cover, a predetermined gap (also referred to as a gap or a gap) is set in advance between the inner peripheral surface of the cover and the heat sink. However, even if the set size of the gap is the same for each lamp, due to the variation in the size of the heat sink and the cover, the size of the gap among the manufactured lamps varies among the lamps. Due to the variation in the size of the gap, the position or posture of the heat sink with respect to the cover differs among the lighting lamps. In addition, since the heat sink holds the board on which the LED light source is mounted, the position or posture of the LED light source with respect to the cover also differs among the lighting lamps. Since the position or posture of the LED light source will affect the performance of the light beam, irradiation angle, and irradiation range of the lighting lamp, there will be deviations in the performance of each lighting lamp.

As shown in FIG. 5 , in Embodiment 1, the light source side positioning portion 67 is a groove having a substantially V-shaped cross section. The light source side positioning portion 67 is formed by a pair of groove slopes 67a (corresponding to the pair of slopes in the present invention) and a concave portion 67b sandwiched by the pair of groove slopes 67a, corresponding to the bottom of the groove. The concave portion 67 b is a portion located closest to the emission side in the light source side positioning portion 67 . When the light source assembly 3 is held inside the cover 2, in a section perpendicular to the long side direction, the central axis O, the center of the light source 4 in the short side direction, the edge 23a of the cover side positioning part 23, and the light source side positioning part 67 The recesses 67b are arranged on a straight line. Here, in the direction perpendicular to the longitudinal direction of the lighting lamp 1 (the Z direction in the drawing), the dimension from the concave portion 67b to the portion of the arc portion 64 that is located closest to the appliance side, that is, the light source side The depth dimension of the positioning portion 67 is D, and is formed so as to satisfy the relationship of D≦L with respect to the height dimension L of the cover-side positioning portion 23 of the cover 2 . In addition, the angle of the groove of the light source side positioning portion 67 centered on the concave portion 67b is β, and is formed so as to satisfy β≥ The relationship of α and the relationship of β<180.

In addition, as a material of the heat sink 6 , it is preferable to use a metal material that is excellent in thermal conductivity and rigidity and has a small coefficient of linear thermal expansion. In Embodiment 1, the heat sink 6 is formed using aluminum. Further, a high reflection film (not shown) having a higher reflectance than the material of the heat sink 6 is formed on the surface of the heat sink 6 , and in Embodiment 1, the high reflection film is a white colored alumina layer.

Here, since the cover 2 and the light source unit 3 are formed of different materials and manufacturing processes, respectively, they have different dimensional variations. Therefore, in order to securely attach the light source unit 3 to the inside of the cover 2 , a predetermined gap (also referred to as a gap, a gap) is provided in advance between the inner peripheral surface of the cover 2 and the light source unit 3 . This gap will be described using FIGS. 4 and 5 . In the cover 2 and the light source unit 3 according to Embodiment 1, at least between the holding protrusion 22 and the protrusion 62 , between the holding protrusion 22 and the light source installation portion 61 , and between the cylindrical portion 21 and the arc portion 64 There is a gap in any one part. By providing a gap between the cover 2 and the light source unit 3, it is possible to absorb the different dimensional deviations in the manufacturing of the cover 2 and the light source unit 3, or to smoothly insert the light source unit 3 into the inside of the cover 2, thereby improving the assemblability. . In addition, since the size of the gap is affected by the variation in size of the cover 2 and the light source unit 3 , variation in the size of the gap occurs among the individual lighting lamps 1 . Therefore, the position or posture of the light source unit 3 with respect to the cover 2 may vary depending on the product, and the performance of each lighting lamp 1 may vary.

However, in the illuminating lamp 1 of Embodiment 1, the cover side positioning part 23 is formed on the cylindrical part 21 of the cover 2, and the light source side positioning part 67 is formed on the arc part 64 of the heat sink 6, respectively. The height dimension L and the depth dimension D of the light source side positioning portion 67 are small. In other words, the light source side positioning portion 67 is formed so as not to completely accommodate the cover side positioning portion 23 . Therefore, the cover 2 and the light source unit 3 of the illuminating lamp 1 according to Embodiment 1 have different dimensional deviations, and when the light source unit 3 is held inside the cover 2, even if a gap is generated between the cover 2 and the light source unit 3, By pressing the ridge 23a of the cover side positioning part 23 to the recess 67b of the light source side positioning part 67, the ridge 23a slides on the groove slope 67a, and the ridge 23a abuts against the recess 67b, and the light source assembly 3 is stably held and fixed. Inside the cover 2. Therefore, in the illuminating lamp 1 according to Embodiment 1, when the light source unit 3 is inserted into the cover 2, the position of the light source unit 3 relative to the cover 2 can be uniquely determined at the position where the ridge portion 23a contacts the recessed portion 67b, so that The deviation of the position of the light source unit 3 relative to the cover 2 is easily suppressed. That is, it is possible to suppress the performance of each illuminating lamp 1 from being inconsistent.

Moreover, even if an external force is applied to the light source unit 3 along the short side direction (direction of arrow Y) of the illuminating lamp 1 in the state where the rib portion 23a is in contact with the recessed portion 67b, the groove slope 67a will contact the rib portion 23a, and reliable The deflection of the light source assembly 3 in the direction of the short side is limited. Therefore, the light source unit 3 is stably held and fixed inside the cover 2 at the position where the edge portion 23 a contacts the recessed portion 67 b.

As described above, the illuminating lamp 1 according to Embodiment 1 can suppress the deviation of the relative position of the light source 4 with respect to the cover 2 compared with the conventional illuminating lamp in which the cover side positioning portion 23 and the light source side positioning portion 67 are not formed, and the light source unit 3 is kept stably fixed inside the cover 2. Therefore, there is little variation in performance, and a lighting lamp with stable quality can be provided.

In addition, in the conventional illuminating lamp without the cover side positioning part 23 and the light source side positioning part 67, due to the combination of the deviation in size of the cover 2 and the heat sink 6, the gap between the two almost disappears, and the cover 2 A large frictional force is generated between the radiator 6 and it may be difficult to insert the radiator 6 into the inside of the cover 2 . However, in the illuminating lamp 1 according to the first embodiment, the resin cover 2 is formed with the cover side positioning part 2 which is a protrusion having the rib 23a, and the metal heat sink 6 is formed with the light source side positioning part which is a groove having the concave part 67b. 67. Therefore, even in the state where the gap between the cover 2 and the heat sink 6 is almost eliminated, the light source module 3 can be pressed from the appliance side to the irradiation side from the appliance side, and the soft resin edge portion 23a is covered with a relatively hard metal. The recessed portion 67b made of this material is crushed to form a new gap, so that the light source module 3 can be easily inserted into the inside of the cover 2 .

Furthermore, in the illuminating lamp 1 according to Embodiment 1, when the light source unit 3 is held inside the cover 2, the concave portion 67b is arranged so that the central axis O and the short-side direction are aligned in a cross-section perpendicular to the long-side direction. The center of the light source 4, the ridge portion 23a of the cover side positioning portion 23, and the concave portion 67b of the light source side positioning portion 67 are on a straight line. Therefore, the light source 4 is positioned at the center in the short-side direction of the lighting lamp 1 at the position where the concave portion 67b abuts on the ridge portion 23a, and deviation of the optical axis of the light in the short-side direction of the lighting lamp 1 can be suppressed.

In addition, when the adhesive is applied between the light source module 3 and the cover 2, before the applied adhesive is cured, the light source module 3 is pressed to make the ribs 23a and the recesses 67b abut against each other. The adhesive is cured in a state where the recess 67b is in contact with the recess 23a. By assembling in this way, the light source module 3 and the cover 2 can be fixed more firmly in a state where the edge portion 23a and the recessed portion 67b are in contact, and performance variations can be further reduced.

8 is an enlarged view of the cover-side positioning portion and the light source-side positioning portion when the light source unit is biased toward the emission side in the illuminating lamp 1 according to Embodiment 1. FIG. In addition, when the light source installation portion 61 of the light source unit 3 abuts against the holding protrusion 22 of the cover 2, that is, when the light source unit 3 is biased toward the emission side, it is further preferable that the gap formed between the edge portion 23a and the concave portion 67b When the width of the gap is h, the dimension L of the protrusion height of the cover side positioning portion 23 satisfies the relationship of L>h, and the dimension D of the depth of the light source side positioning portion 67 satisfies the relationship of D>h. By satisfying this relationship, when the light source module 3 is held inside the cover 2, the ribs 23a of the cover side positioning portion 23 must be positioned between the groove slopes 67a of the light source side positioning portion 67, so the following effects can be reliably obtained. That is, it is possible to easily suppress the deviation of the position of the light source module 3 relative to the cover 2 .

Furthermore, in the illuminating lamp 1 according to Embodiment 1, the cover-side positioning portion 23 is a protrusion having a rib portion 23a and a protrusion slope 23b, and the light source-side positioning portion 67 is a groove having a groove slope 67a and a recess 67b, but the present invention is not limited thereto. , it is also possible that the cover side positioning portion is a groove having a groove slope and a concave portion like the light source side positioning portion 67 of Embodiment 1, and the light source side positioning portion has a protruding slope like the cover side positioning portion 67 of Embodiment 1. And the protrusions of the ribs. In this case, the height dimension of the light source side positioning part is a value equal to or larger than the depth dimension of the cover side positioning part. In addition, the angle of the inner corner of the light source side positioning part centering on the edge part is a value equal to or smaller than the angle of the outer corner of the cover side positioning part centering on the concave part.

In addition, the shapes of the cover 2 and the heat sink 6 are not limited to the shapes of the first embodiment, as long as the cover side positioning part 23 and the light source side positioning part 67 are formed, for example, they may be the first to the first embodiment of the first embodiment. The shape described in the modified example of 5. In addition, in the first to fifth modifications of the first embodiment, the shapes of the cover 2 or the heat sink 6 are different, and other configurations are substantially the same as those of the first embodiment, so description thereof will be omitted.

A first modified example of Embodiment 1.

9 is a cross-sectional view of an illuminating lamp according to a first modification of Embodiment 1. FIG. The illuminating lamp 1a according to the first modified example of the first embodiment differs from the illuminating lamp 1 according to the first embodiment in that the number of the clip fixing parts 66 of the heat sink 6a is two. Moreover, the shape of the cover 2a of the 1st modification of Embodiment 1 is substantially the same as the cover 2 of Embodiment 1. As shown in FIG. Since the heat sink 6a of the first modified example of Embodiment 1 is not formed with the jig fixing portion 66 without the screw hole 65a, it has a simpler shape than the heat sink 6 of Embodiment 1, and can Improvement in formability is expected.

A second modified example of Embodiment 1.

10 is a cross-sectional view of an illuminating lamp according to a second modified example of Embodiment 1. FIG. The illuminating lamp 1b of the second modified example of the first embodiment is different from the illuminating lamp 1 of the first embodiment in that the light source mounting portion 61 and the arc portion 64 of the heat sink 6b are shorter, and the protrusion 62 is placed farther from the light source. Both ends in the short-side direction (direction of arrow Y) of the mounting portion 61 extend, and the inner peripheral surfaces of both ends of the arc portion 64 are integrated with the side wall portion 63 . In addition, the holding protrusion 22 of the cover 2b is located closer to the appliance side than the cover 2 of Embodiment 1, from the plane on the exit side of the holding protrusion 22 of the cover 2b to the plane parallel to the plane on the exit side and passing through the central axis O. The distance H2 to the plane is longer than the distance H in the first embodiment. The device-side surface of the holding protrusion 22 faces the emission-side surface of the end portion of the arc portion 64 in the short-side direction. Since the holding protrusion 22 of the cover 2b according to the second modified example of the first embodiment is located closer to the appliance than the cover 2 of the first embodiment, the irradiation angle of the illuminating lamp 1b can be increased.

A third modified example of Embodiment 1.

11 is a cross-sectional view of an illuminating lamp according to a third modified example of Embodiment 1. FIG. The illuminating lamp 1c of the third modified example of Embodiment 1 differs from the illuminating lamp 1b of the third modified example of Embodiment 1 in that the number of clip fixing portions 66 of the heat sink 6c is two. Moreover, the shape of the cover 2c of the 3rd modification of Embodiment 1 is substantially the same as the cover 2b of the 2nd modification of Embodiment 1. As shown in FIG. Since the cover 2c of the third modified example of Embodiment 1 is not formed with the clamp fixing portion 66 without the screw hole 65a, it has a simpler shape than the heat sink 6b of the second modified example of Embodiment 1, and is similar to the radiator 6b. Compared with that, improvement in formability can be expected.

A fourth modified example of Embodiment 1.

12 is a cross-sectional view of an illuminating lamp according to a fourth modification of Embodiment 1. FIG. The lighting lamp 1d according to the fourth modification of the first embodiment differs from the lighting lamp 1 of the first embodiment in that the clamp fixing part 66 forming the screw hole 65a of the heat sink 6d is integrated with the screw fixing part 65 . In addition, the shape of the cover 2d of the fourth modified example of the first embodiment is substantially the same as that of the cover 2 of the first embodiment. Since the heat sink 6d in the fourth modified example of Embodiment 1 connects the light source installation portion 61 and the arc portion 64 by the screw fixing portion 65, the rigidity of the heat sink is improved, and warping and bending of the lighting lamp are less likely to occur.

Fifth Modification of Embodiment 1.

13 is a cross-sectional view of an illuminating lamp according to a fifth modification of Embodiment 1. FIG. 14 is an enlarged perspective view of the other end portion (the front end side of the arrow X) of the heat sink according to the fifth modified example of the first embodiment. The lighting lamp 1e according to the fifth modified example of the first embodiment differs from the lighting lamp 1 of the first embodiment in that the light source side positioning portion 67 of the heat sink 6e, the cover side positioning portion 23 of the cover 2e, and the lighting lamp 1e The central axis O of 2 is not located on a straight line, but the light source side positioning part 67 and the cover side positioning part 23 are respectively provided at two places. Even in the case of the fifth modified example of Embodiment 1, by pressing the light source unit 3 toward the appliance side, the edges 23a of the respective cover-side positioning portions 23 slide on the groove slopes 67a until the respective cover-side positioning portions 23 Since the ridge portion 23a is in contact with the concave portion 67b of the light source side positioning portion 67, the same effect as that of the first embodiment can be obtained.

In addition, in the illuminating lamp 1 according to the first embodiment, since the light source side positioning portion 67 and the cover side positioning portion 23 are respectively provided at only one place, the light source unit 3 uses the portion where the rib portion 23a and the concave portion 67b contact each other as a fulcrum. And it is inclined relative to the cover 2 . The inclination of the light source assembly 3 relative to the cover 2 will also lead to deviations in optical characteristics. However, in the illuminating lamp 1e according to the fifth modified example of Embodiment 1, the light source side positioning portion 67 and the cover side positioning portion 23 are respectively provided at two places, so there are also two places where the edge portion 23a abuts with the recessed portion 67b. , it is possible to suppress the inclination of the light source module 3 with respect to the cover 2e, and it is possible to further suppress variations in optical characteristics. In addition, in the fifth modified example of Embodiment 1, the light source side positioning part 67 and the cover side positioning part 23 are respectively provided at two places, and even if there are three or more places, the same effect can be obtained. The positioning part 67 and the cover side positioning part 23 can obtain the effect of suppressing the inclination of the light source module relative to the cover.

Implementation mode 2.

Fig. 15 is a cross-sectional view of a lighting lamp according to Embodiment 2. The illuminating lamp 1f of the second embodiment is different from the illuminating lamp 1 of the first embodiment in that the cylindrical portion 21 and the holding protrusion 22 of the cover 2f are formed of different materials. In addition, about the structure other than the cover 2f in the illuminating lamp 1f of Embodiment 2, it is substantially the same as the heat sink 6 of Embodiment 1. As shown in FIG. In addition, the illuminating lamp 1f of Embodiment 2 can be attached to the lighting fixture 101 of Embodiment 1, and when electric power is supplied from the lighting fixture 101, the illuminating lamp 1f is turned on.

The material forming the cylindrical portion 21 is referred to as a first cover material. The first cover material is the same as the material forming the cover 2 in Embodiment 1, and is a light-transmitting material, for example, a light-transmitting resin such as polycarbonate or acrylic resin. In addition, the cover-side positioning portion 23 is also formed of the first cover material.

In addition, the material which forms the holding protrusion part 22 is called a 2nd cover material. The second cover material is a material whose reflectivity is higher than that of the first cover material. For example, a highly reflective resin material can be enumerated. It is made by mixing materials that increase reflectivity, such as titanium dioxide, in a predetermined weight ratio.

The cover 2 f in which the cylindrical part 21 and the holding protrusion part 22 are formed of different materials is manufactured by, for example, two-color molding. Here, two-color molding refers to a method in which, for example, two different resin compositions are melt-extruded from a plurality of different extruders, and then placed in one die connected to a plurality of extruders Integrate, and then cool and solidify to obtain a composite molded body of two resin compositions that are fused and integrated on the surface. In the case of Embodiment 2, the first cover material is melted and extruded from the extruder forming the cylindrical portion 21 and the cover side positioning portion 23, and the second cover material is melted and extruded from the extruder forming the holding protrusion 22. Extruded by machine, after being integrated in one mold, it is cooled and solidified to form the cover 2f.

In addition, there is a path of light in which part of the light emitted from the light source 4 is reflected by the cylindrical portion 21 and returned to the appliance side as shown by the arrow a in FIG. External exposure. Since the reflectance of the holding protrusion 22 of the illuminating lamp 1f of the second embodiment is higher than that of the cylindrical portion 21, compared with the illuminating lamp in which the cylindrical portion 21 and the holding protrusion 22 are formed of the same material as in the first embodiment, The beam of light reflected by the holding protrusion 22 increases. Therefore, compared with the illuminating lamp 1 of the first embodiment, the luminous flux of light irradiated from the illuminating lamp 1f in the illuminating lamp 1f of the second embodiment is increased, and the luminous efficiency of the illuminating lamp 1f can be improved.

In addition, the shape of the cover to improve the luminous efficiency of the illuminating lamp is not limited to the shape of the cover 2f in Embodiment 2, as long as the holding protrusion 22 is formed of a material with high reflectivity, for example, it may be the shape of the second embodiment in Embodiment 2, respectively. The shape described in the modification examples 1 to 3. In addition, in the first to third modification examples of Embodiment 1, the shape of the cover 2 is different, and the other configurations are substantially the same as those of Embodiment 2, so description thereof will be omitted.

The first modified example of Embodiment 2.

16 is a cross-sectional view of an illuminating lamp according to a first modification of Embodiment 2. FIG. The illuminating lamp 1g of the first modified example of the second embodiment differs from the illuminating lamp 1f of the second embodiment in that a part of the cylindrical portion 21 of the cover 2g is formed of the second cover material.

The cylindrical part 21 of the cover 2g passes through a pair of holding protrusions 22, an emission-side light-transmitting part 21a located on the emission side from the holding protrusions 22, and an appliance side located on the appliance side from the holding protrusions 22. The light transmitting part 21b is integrally formed in a cylindrical shape. In addition, the end surface exposed on the outer peripheral surface of the cylindrical part 21 in the holding protrusion part 22 is called the exposure side end surface 22a. Furthermore, the holding protrusion 22 is located closer to the appliance side than the central axis O of the lighting lamp 1g. In addition, the pair of holding protrusions 22, the emission-side light-transmitting portion 21a, and the appliance-side light-transmitting portion 21b are formed so as to extend in the entire longitudinal direction (direction of arrow X) of the cover 2g, and the cover 2 is cut perpendicular to the longitudinal direction. However, the obtained cross-section is always the cross-sectional shape as shown in FIG. 16 .

The emission-side light-transmitting portion 21 a and the appliance-side light-transmitting portion 21 b are formed of the first cover material described in the second embodiment. In addition, the holding protrusion 22 is formed of the second cover material described in the second embodiment. Therefore, the exposed end surface 22d of the holding protrusion 22 on the outer periphery of the cylindrical portion 21 of the cover 2g is formed of the second cover material, and has a surface made of the second cover material on the outer periphery of the lighting lamp 1 .

Since the reflectance of the holding protrusion 22 of the cover 2g is higher than that of the light-emitting side light-transmitting portion 21a, for the same reason as that of the second embodiment, the lighting lamp 1g of Modification 1 of the second embodiment can achieve improved luminous efficiency of the lighting lamp 1g. Effect. In addition, since the reflectance of the second cover material is higher than that of the first cover material and the appearance is different, the exposed side end surface 22a of the holding protrusion 22 exposed on the outer periphery of the lighting lamp 1g becomes the same as when the lighting lamp 1g is attached to the lighting fixture 101. The mark designating the orientation of the illuminating lamp 1g can be utilized by the user to easily attach the illuminating lamp 1g to the lighting fixture 101 .

A second modified example of Embodiment 2.

17 is a cross-sectional view of an illuminating lamp according to a second modified example of the second embodiment. The illuminating lamp 1h according to the second modified example of the second embodiment differs from the illuminating lamp 1g according to the first modified example of the second embodiment in that the equipment side reflective portion 21c of the cover 2h corresponding to the equipment side light transmitting portion 21b It is made of the same material as the holding protrusion 22 .

The cylindrical part 21 of cover 2h is formed in cylindrical shape by integrating the emission side light transmission part 21b and the equipment side reflection part 21c. In addition, the emission-side light-transmitting portion 21a of the cover 2h is formed of the first cover material described in Embodiment 1, and the device-side reflection portion 27 and holding protrusion 22 are formed of the second cover material described in Embodiment 1. Therefore, in the illuminating lamp 1h of the second modified example of the second embodiment, the surface formed of the second cover material is also exposed on the outer periphery of the cover 2h.

For the same reason as the first modification of Embodiment 1, the illuminating lamp 1h of the second modification of Embodiment 2 can also achieve the effect of improving the luminous efficiency of the illuminating lamp 1h and the user can easily attach the illuminating lamp 1h to the The effect of the lighting fixture 101.

In addition, since the second cover material does not need to have translucency, it is also possible to mix materials that improve other physical properties besides materials that improve reflectance. In particular, the thermal conductivity of the appliance-side reflector 27 is increased by mixing a material that increases thermal conductivity such as a thermally conductive filler with the second cover material, thereby increasing the thermal conductivity from the radiator 6 to the cover 2h, and improving the heat dissipation performance of the lighting lamp. In addition, the rigidity of the cover 2 can be increased by mixing a highly rigid material such as glass filler with the second cover material.

A third modified example of Embodiment 2.

18 is a cross-sectional view of an illuminating lamp according to a third modification of Embodiment 2. FIG. The illuminating lamp 1i of the third modified example of the second embodiment differs from the illuminating lamp 1f of the second embodiment in that the plane on the emission side is inclined relative to the plane on the appliance side so that the holding protrusion 22 The inner peripheral surface of 2i increases in thickness.

In the third modified example of Embodiment 2, the holding protrusion 22 is formed such that the plane on the emission side is inclined at an angle θ with respect to the plane on the device side, and its thickness increases as it approaches the inner peripheral surface of the cylindrical portion 21 . In addition, in Embodiment 1, the angle θ is about 15 degrees.

As shown in FIG. 18 , the light emitted from the light source 4 spreads out at an irradiation angle γ symmetrically with respect to the axis (direction of arrow Y) perpendicular to the light emitting surface of the light source 4. Among the lights, the light irradiated from outside the range of the irradiation angle γ of the light source 4 is reflected light reflected by the substrate 5 , the heat sink 6 , the cylindrical portion 21 or the holding protrusion 22 . Furthermore, the farther away from the range of the irradiation angle γ, the greater the ratio of the light irradiated from the illuminating lamp 1 with a large number of reflections. Therefore, in the interval δ from the range of the irradiation angle γ to the holding protrusion 22, the closer to the holding protrusion 22, the smaller the beam of the irradiated light, and the difference from the beam of light irradiated from the range of the irradiation angle γ becomes smaller. bigger. At this time, when the difference between the light beam at any part in the interval δ and the light beam irradiated from the range of the irradiation angle γ is greater than a certain degree, the user will feel that the part is dark, and feel that the light source of the lighting lamp 1 There is unevenness in brightness. In particular, in the illuminating lamp 1 , there are portions where light is not irradiated due to holding the protrusion 22 and the heat sink 6 , and therefore, the darkened portion is more conspicuous.

However, the lighting lamp 1i according to the third modified example of the second embodiment is formed such that the thickness of the holding protrusion 22 becomes thicker as the output-side holding protrusion 22 goes toward the inner peripheral surface of the cover 2i. In this way, compared with the case where the thickness of the projection 22 on the emission side is uniform, the section δ can be narrowed, and it is possible to eliminate the dark part perceived by the user, and prevent the user from feeling unevenness in brightness.

In addition, in the third modified example of Embodiment 2, the angle θ is set to about 15 degrees, but the part where the user perceives darkness depends on the shape of the surface of the light source unit 3 facing the exit-side space 25 and the user's attitude. Feeling, so the angle θ is not limited to 15 degrees, it can be any angle. However, as mentioned above, only outside the range of the radiation angle γ of the light source 4 will form a region where the user feels dim. Since the irradiation angle of 1i becomes smaller than the irradiation angle of the light source 4, it is preferable to avoid setting the angle θ such that the protrusion 22 is kept within the range of the irradiation angle γ. Specifically, the angle θ is preferably set at θ=90−(γ/2) degrees or less. For example, when the irradiation angle γ is 120 degrees, the angle θ is preferably set at 30 degrees or less.

In the above-mentioned embodiments and modifications, the shape of the base is described as a straight tube lamp based on JEL801, but this embodiment can also be applied to straight tube lamps and other straight tube LEDs whose base shape is based on JEL802, for example. . In addition, this embodiment can also be applied to bases of other shapes.

The embodiments and modifications have been described above, but two or more of these embodiments and modifications may be implemented in combination. Alternatively, one of these embodiments and modified examples may be partially implemented. Alternatively, two or more of these embodiments and modifications may be partially combined and implemented. In addition, this invention is not limited to these embodiment and modification, Various modifications are possible as needed.
