Abstract

The invention discloses a kind of lens, described lens are cylindrical lens, are provided with the fovea superior conical surface and the recessed conical surface; The described fovea superior conical surface and the recessed conical surface form hourglass shape; Described source light enters concave cone face, sends after lens reflection from another concave cone face; A kind of lens of the present invention, can at some poor weather such as foggy weather, night, rainy days, by light by carrying out different refractions after these lens, light is refracted as, red, orange, yellow, green, cyan, blue, purple, to reach eye-catching object, penetrability is strong, long transmission distance.

Description

a lens

technical field

The invention relates to a lens.

Background technique

Lenses are widely used in various fields such as security, digital cameras, lasers, and optical instruments. In the prior art, there are few applications of lenses in providing light intensity for automobile lights. For the processing of light intensity of existing automobile fog lights For example, in some poor environments such as foggy weather, nighttime, and rainy days, the strong light of the headlights has a greater stimulus to the eyes of pedestrians and drivers, and the penetrating power is poor, which is easy for pedestrians and drivers. Halo, which brings certain harm to road traffic.

Contents of the invention

(1) Technical problems to be solved

In order to solve the above problems, the present invention proposes a lens, which can effectively improve the penetrability of automobile fog lamps, and the color is more eye-catching, and it is difficult to cause halos to pedestrians and other vehicle drivers.

(2) Technical solution

A lens of the present invention is characterized in that: the lens is a cylindrical lens, and is provided with an upper concave cone surface and a lower concave cone surface; the upper concave cone surface and the lower concave cone surface form an hourglass shape; the light source The light enters the concave cone surface, is refracted by the lens, and then emerges from the other concave cone surface.

Further, a cone point is formed at the junction of the upper concave cone surface and the lower concave cone surface; the position of the cone point is confirmed by different refractive indices.

Further, the solid part of the lens in the lens forms an axicon. After the light from the light source enters the axicon, it emits seven kinds of red, orange, yellow, green, blue, blue and purple because of its different refractive index in the same medium. warning light.

(3) Beneficial effects

Compared with the prior art, the present invention has the following beneficial effects: a kind of lens of the present invention, the light is refracted differently after passing through the lens, and the light is refracted into red, orange, yellow, green, blue, blue, purple Equal visible color to achieve the purpose of eye-catching and reminding others, strong penetrability and long transmission distance.

detailed description

Example 1:

A kind of lens as shown in Figure 1 and Figure 2 is characterized in that: described lens is cylindrical lens, is provided with upper concave cone surface 1 and lower concave cone surface 2; Said upper concave cone surface 1 and lower concave cone surface An hourglass shape is formed on the surface 2; the light source light 5 enters the concave cone surface, is refracted by the lens, and is emitted from another concave cone surface.

A cone point 3 is formed at the junction of the upper concave cone surface 1 and the lower concave cone surface 2; the position of the cone point 3 is confirmed by different refractive indices.

The solid part of the lens in the lens forms the axicon 4. After the light source light 5 enters the axicon 4, it emits seven kinds of red, orange, yellow, green, blue, blue and purple because of its different refractive index in the same medium. The warning light 6.

Among them, the height from the cone mouth of the upper concave cone surface 1 to the cone point 3 is 45 mm, and the height from the cone mouth of the lower concave cone surface 2 to the cone point 3 is 15 mm; the cone mouth of the upper concave cone surface 1 and the lower concave cone surface 2 The aperture is 20mm, the central thickness is 13±1%mm; the light intensity angle of the lens is 6.3±1% degree; the wavelength range of the lens refraction is 390nm～780nm.

After the light source light 5 enters the lens, it is affected by the axicon, and its refractive index is different, thereby emitting warning light 6 of different colors.

Example 2:

The height from the cone mouth of the upper concave cone surface 1 to the cone point 3 is 50 mm, and the height from the cone mouth of the lower concave cone surface 2 to the cone point 3 is 10 mm; the cone diameters of the upper concave cone surface 1 and the lower concave cone surface 2 are 18 mm, the center thickness is 15±1% mm; the lens light intensity angle is 6.7±1% degrees; the wavelength range of lens refraction is 390nm～780nm.

The lens of the present invention can refract light differently after passing through the lens in foggy weather, night, rainy weather, etc., and refract the light into red, orange, yellow, green, blue, blue , purple, in order to achieve eye-catching purposes, strong penetration, long transmission distance.

The above-mentioned embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Under the premise of not departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention, and the technical content claimed in the present invention has been fully described in the claims.

Claims (1)

1. lens, is characterized in that: described lens are cylindrical lens, are provided with the fovea superior conical surface and the recessed conical surface; The described fovea superior conical surface and the recessed conical surface form hourglass shape; Source light enters the described fovea superior conical surface or the described recessed conical surface, sends after lens reflection from the described recessed conical surface or the described fovea superior conical surface; The described fovea superior conical surface and recessed conical surface junction form a cone point; The position of described cone point is confirmed by different refractivity; In described lens, lens body part forms axicon lens, after source light enters axicon lens, because its refractive index in same medium is different, thus launches the warning light of red, orange, yellow, green, cyan, blue, purple seven kinds.
