背景技术Background technique
目前在照明、投影等领域，通过灯泡获得白光难以满足高亮度等要求，利用半导体光源获得白光的技术方案越来越普及。由于白光是宽谱光，无法直接利用半导体发光获得白光，因此，目前利用半导体产生白光的方式主要有两种。一种是在蓝光半导体出光面覆盖荧光粉，利用蓝光半导体发光器件激发荧光粉，利用激发产生的黄光和未被吸收的蓝光合光产生白光；另一种方式是分成两个光路，分别获得蓝光激发荧光粉产生的黄光和蓝光半导体发出的蓝光，利用光路进行合光。前者调节出射光白光的色温需要通过调节荧光粉的含量实现，这种方式虽然能够实现色温的宽幅度调节，但是两者的亮度差别太大；而后者需要借助光路合光，光学系统体积大、复杂。At present, in the fields of lighting and projection, it is difficult to obtain white light through bulbs to meet the requirements of high brightness, and the technical solution of using semiconductor light sources to obtain white light is becoming more and more popular. Since white light is a wide-spectrum light, it is impossible to directly use semiconductors to emit white light. Therefore, there are currently two ways to use semiconductors to generate white light. One is to cover the phosphor powder on the light-emitting surface of the blue light semiconductor, use the blue light semiconductor light-emitting device to excite the phosphor powder, and use the yellow light generated by the excitation to combine with the unabsorbed blue light to generate white light; the other way is to divide into two light paths to obtain The blue light excites the yellow light generated by the fluorescent powder and the blue light emitted by the blue semiconductor, and uses the optical path to combine light. The former needs to adjust the color temperature of the outgoing white light by adjusting the content of phosphor powder. Although this method can achieve a wide range of color temperature adjustment, the brightness difference between the two is too large; while the latter needs to combine light with the help of an optical path, and the optical system is large in size. complex.

具体实施方式detailed description
本发明的波长转换装置的发光层中同时含有荧光粉、高折射散射粒子、低折射散射粒子和粘结材料，利用高折射散射粒子与低折射散射粒子的体积比来对出射光的色温进行调节。The light-emitting layer of the wavelength conversion device of the present invention contains fluorescent powder, high-refraction scattering particles, low-refraction scattering particles and bonding materials at the same time, and the color temperature of the outgoing light is adjusted by using the volume ratio of high-refraction scattering particles and low-refraction scattering particles .
一般来说，散射粒子与周围介质的折射率差别越大，对光线的折射作用越强，因而当光线入射到发光层后，光进入发光层的深度越浅，也即激发光在发光层中的激发深度越浅。对比本发明来说，发光层中的高折射散射粒子越多，蓝光进入波长转换层的发光层的深度越浅，造成发光层对蓝光的吸收越少，更多的蓝光被反射出发光层，从而最终出射光中的蓝光比例较大，得到的白光的色温大。Generally speaking, the greater the difference in refractive index between the scattering particles and the surrounding medium, the stronger the refraction effect on light. Therefore, when the light enters the light-emitting layer, the depth of light entering the light-emitting layer is shallower, that is, the excitation light is in the light-emitting layer. The shallower the excitation depth. Compared with the present invention, the more high-refraction scattering particles in the light-emitting layer, the shallower the depth of blue light entering the light-emitting layer of the wavelength conversion layer, resulting in less absorption of blue light by the light-emitting layer, and more blue light is reflected out of the light-emitting layer. Therefore, the proportion of blue light in the final emitted light is relatively large, and the color temperature of the obtained white light is large.
由于介质对短波长的光的折射能力更强，因而高低折射散射粒子的体积比对蓝光的影响明显高于对黄光的影响。在出射白光中，蓝光对色温的影响大，而黄光对亮度的影响大。因此，通过调节高低折射散射粒子的体积比，能够在不明显改变出射光亮度的情况下，调节出射光的色温，避免了现有技术中调节荧光粉带来的亮度变化的缺陷。Since the medium has a stronger refraction ability for short-wavelength light, the volume ratio of high and low refraction scattering particles has a significantly higher impact on blue light than on yellow light. Among outgoing white light, blue light has a great influence on color temperature, while yellow light has a great influence on brightness. Therefore, by adjusting the volume ratio of the high and low refraction scattering particles, the color temperature of the outgoing light can be adjusted without significantly changing the brightness of the outgoing light, which avoids the defect of brightness changes caused by adjusting phosphor powder in the prior art.
下面结合附图和实施方式对本发明实施例进行详细说明。Embodiments of the present invention will be described in detail below with reference to the drawings and implementation methods.
请参见图1，图1为本发明实施例一的光源装置的结构示意图。如图所示，光源装置包括蓝光光源200和波长转换装置100，蓝光光源200发出的光入射于波长转换装置100，波长转换装置100包括发光层110和反射层120，其中，反射层120位于发光层110远离光入射侧的表面。Please refer to FIG. 1 , which is a schematic structural diagram of a light source device according to Embodiment 1 of the present invention. As shown in the figure, the light source device includes a blue light source 200 and a wavelength conversion device 100, the light emitted by the blue light source 200 is incident on the wavelength conversion device 100, and the wavelength conversion device 100 includes a light emitting layer 110 and a reflective layer 120, wherein the reflective layer 120 is located Layer 110 is the surface remote from the light incident side.
在本实施例中，发光层110由荧光粉、高折射散射粒子、低折射散射粒子和粘结材料等材料组成，发光层110包括两个区域：第一区域111和第二区域112。其中，第一区域111的高折射散射粒子与低折射散射粒子的体积比大于第二区域112的高折射散射粒子与低折射散射粒子的体积比。In this embodiment, the luminescent layer 110 is composed of materials such as phosphor, high-refractive scattering particles, low-refractive scattering particles, and bonding materials. The luminescent layer 110 includes two regions: a first region 111 and a second region 112 . Wherein, the volume ratio of the high-refraction scattering particles to the low-refraction scattering particles in the first region 111 is greater than the volume ratio of the high-refraction scattering particles to the low-refraction scattering particles in the second region 112 .
本实施例中，光源装置还包括调节装置(图中未示出)，用于调节使蓝光光源200发出的光入射于第一区域111或第二区域112。当蓝光光源发出的光照射第一区域时，波长转换装置发出第一出射光，当蓝光光源发出的光照射第二区域时，波长转换装置发出第二出射光，第一出射光的色温高于第二出射光的色温。该调节装置可以是用于驱动波长转换装置100和/或蓝光光源200并使其移动的装置；也可以是一可调节的光学装置(如一可调节反射镜)，位于蓝光光源200与波长转换装置100之间。In this embodiment, the light source device further includes an adjustment device (not shown in the figure), which is used to adjust the light emitted by the blue light source 200 to be incident on the first area 111 or the second area 112 . When the light emitted by the blue light source illuminates the first area, the wavelength conversion device emits the first outgoing light, and when the light emitted by the blue light source illuminates the second area, the wavelength conversion device emits the second outgoing light, and the color temperature of the first outgoing light is higher than The color temperature of the second outgoing light. The adjustment device can be used to drive the wavelength conversion device 100 and/or the blue light source 200 and make it move; it can also be an adjustable optical device (such as an adjustable reflector), located between the blue light source 200 and the wavelength conversion device. Between 100.
在本实施例中，第一区域111和第二区域112中的荧光粉为相同的荧光粉，因此当蓝光光源分别照射第一区域111和第二区域112时，发出的光的颜色不会有太大差别。在本实施例中，第一区域111和第二区域112中的荧光粉都是黄光荧光粉，如YAG荧光粉，荧光粉发出的黄光可以与蓝光光源发出的蓝光合光后形成白光。In this embodiment, the phosphors in the first area 111 and the second area 112 are the same phosphor, so when the blue light source irradiates the first area 111 and the second area 112 respectively, the color of the emitted light will not be different. Big difference. In this embodiment, the phosphors in the first region 111 and the second region 112 are both yellow phosphors, such as YAG phosphors, and the yellow light emitted by the phosphors can combine with the blue light emitted by the blue light source to form white light.
在本实施例中，第一区域111和第二区域112中的荧光粉的体积分数相同。发光层110的出射光亮度主要取决于荧光粉的体积分数，在荧光粉的体积分数相同的情况下，第一区域111和第二区域112的出射光亮度更为接近，同时，该技术方案也便于控制产品良率。In this embodiment, the phosphor powder in the first region 111 and the second region 112 have the same volume fraction. The brightness of the emitted light from the luminescent layer 110 mainly depends on the volume fraction of the phosphor powder. When the volume fraction of the phosphor powder is the same, the brightness of the emitted light from the first region 111 and the second region 112 are closer. At the same time, this technical solution also Easy to control product yield.
本实施例中，高折射散射粒子的折射率大于1.8，而低折射散射粒子的折射率小于1.8且大于1.6。折射率越大，蓝光在高折射散射粒子的界面折射后的角度变化越大，蓝光在发光层110的激发深度越浅。低折射散射粒子的折射率小于高折射散射粒子的折射率，但是低折射散射粒子的折射率高于粘结材料的折射率，否则其散射反射作用将不明显。在本发明的实施方式中，无论高折射散射粒子还是低折射散射粒子，除了其本身的反射作用外，都依赖于与粘结材料的折射率差而产生的散射作用。In this embodiment, the refractive index of the high-refractive scattering particles is greater than 1.8, and the refractive index of the low-refractive scattering particles is less than 1.8 and greater than 1.6. The greater the refractive index, the greater the angle change of the blue light after refraction at the interface of the high-refractive scattering particles, and the shallower the excitation depth of the blue light in the light-emitting layer 110 . The refractive index of the low-refraction scattering particles is smaller than that of the high-refraction scattering particles, but the refractive index of the low-refraction scattering particles is higher than that of the bonding material, otherwise the scattering reflection effect will not be obvious. In the embodiment of the present invention, regardless of the high-refractive scattering particles or the low-refractive scattering particles, in addition to their own reflection, they all rely on the scattering effect caused by the difference in refractive index with the binder material.
本实施例中，高折射散射粒子包括氧化钛、氧化锆、氧化锌中的至少一种，低折射散射粒子包括氧化铝、氧化钇、硫酸钡中的至少一种。该高低折射散射粒子的粒径与可见光的波长相近，肉眼观察表现出白色，能够对可见光进行散射和反射。In this embodiment, the high-refractive scattering particles include at least one of titanium oxide, zirconium oxide, and zinc oxide, and the low-refractive scattering particles include at least one of aluminum oxide, yttrium oxide, and barium sulfate. The particle size of the high and low refraction scattering particles is close to the wavelength of visible light, and it appears white when observed by naked eyes, and can scatter and reflect visible light.

Optionally, the bonding material includes one of organic silica gel, epoxy resin, and glass powder.

The thermal conductivity of the thermally conductive substrate is higher than 80W/mK, and can be a ceramic substrate or a metal substrate.

The fluorescent color wheel is driven to rotate by a motor, so that the blue light source irradiates the first area and the second area of the fluorescent color wheel at different times, thereby emitting light with different color temperatures.
