Description

Car light thick wall light emitting structure

Technical Field

The utility model relates to a car light especially relates to a car light thick wall light-emitting structure.

Background

With the rapid development of the automobile industry and the improvement of human civilization, the requirements on the color value of the automobile are higher and higher, and modeling designers also continuously innovate and explore the modeling design of the automobile lamp. However, the vehicle lamp is different from other parts, and each lighting function of the vehicle lamp is required to meet the requirement of the light distribution regulation and the requirement on the uniformity of the spot lamp is higher and higher. This presents higher demands and challenges for different models to achieve legislation and good lighting uniformity.

Under the condition of a certain modeling, in order to meet the requirement of a light distribution regulation and realize an excellent lighting effect, the general method is to increase the luminous flux, and the increase of the luminous flux often needs to replace a light source with larger power, which inevitably causes the increase of the cost. Even if the light source is not replaced, the power of the whole system is increased, so that higher requirements on the heat resistance of the system are made, and the cost of the system is indirectly increased.

Another way to meet regulations and optimize the lighting effect is to increase the number of light sources and to increase the energy input in order to obtain an output of energy that meets the regulations. This solution can effectively solve the legislation problem, but causes a considerable increase in cost.

The thick-walled focalizer can achieve better lighting uniformity than the reflective optical system (see fig. 1), and generally, the thick-walled focalizer can be divided into a direct-type focalizer (see fig. 2) and a reflective focalizer (see fig. 3). The energy utilization rate of the direct-injection type focalizer is higher than that of the reflection type focalizer, and the direct-injection type focalizer is better in economy. However, for a lamp with a relatively large inclination, even if the fish eye at the front end of the conventional thick-wall focuser is turned over, the light is difficult to deflect to a test point, and meanwhile, the turned-over fish eye forms a dark area for forward lighting.

Since light is transmitted to the interface of two media, refraction usually occurs, and it is just by utilizing the refraction phenomenon of light that the transmission path of light can be effectively controlled, so as to realize accurate optimization regulation and lighting uniformity.

Most of light rays designed by the conventional direct-type focusing device are refracted twice, as shown in fig. 4, the light rays are emitted from the light source 1, enter the focusing device 2 through the first refraction and are transmitted in the focusing device 2, and the light rays reaching the surface of the focusing device 2 are refracted for the second time through the fish eye surface at the front end.

Detailed Description

The following describes a thick-wall light-emitting structure of a car lamp according to the present invention with reference to the accompanying drawings and embodiments.

As shown in fig. 5, the utility model discloses a car light thick wall light emitting structure is the same with prior art, also mainly includes luminescent light source 1 and direct injection type thick wall focuser 2 equally, and the difference is, and this thick wall focuser 2 has carried out ingenious hollow out design on the basis of traditional direct injection type focuser, has designed the hollow out construction 3 that has the number of times that can increase light source light refraction promptly at 2 internal design of focuser. As an embodiment, the hollow structure 3 is a hollow groove disposed along the length direction of the thick-walled focalizer 2, so that the light can exit through four refractions. Of course, other numbers or shapes of hollowed-out structures may be used as desired.

And optical patterns such as saw-tooth shapes and the like are respectively arranged on the surfaces of the two sides of the hollow structure.

Thus, when light rays start from the light emitting source 1, enter the focalizer 2 through first refraction and propagate in the focalizer 2, reach the inner surface of the focalizer 2 at the hollow structure, and are refracted and emitted to the light thinning medium-air in the hollow through the pattern surface 4 with the optical patterns, the light rays are further directly irradiated onto the pattern surface 4 on the outer surface of the hollow structure 3, and are refracted by the air (light thinning medium) into the focalizer 2 (optically dense medium), the light rays propagate in the focalizer 2 again, and finally reach the surface of the focalizer 2 and are emitted through the fourth refracted light rays of the fish eye surface 5 at the front end (see the broken line arrow in fig. 5 in detail).

To sum up, in order to optimize the regulation and the homogeneity of lighting a lamp, the utility model provides a do not raise the cost, carry out optimal design through ingenious to the focuser to the cooperation is to the decorative pattern type of focuser, and the direction designs with the diffusion, can realize the wide-angle deflection of light, realizes the propagation of effective accurate control light, thereby reaches the purpose of optimizing regulation and homogeneity.
