Embodiment 1

[0045] refer to Figure 5 : This light distribution scheme is realized by adopting LED+reflector+discrete material inner light distribution mirror, and the continuous and uniform lighting effect of the brake light is obtained. The LED can be arranged on the circuit board, and the light is fully reflected by the reflector and diffused through the inner light distribution mirror with discrete materials, achieving the effect of uniform light emission. The base material of the internal light distribution lens can be PMMA or PC material, and the discrete material can be DF22 or DF23. It can be understood that if the discrete material is configured in the base material of the inner light distribution mirror, it can be configured in various combinations, such as the configuration of PMMA+DF22, the configuration of PMMA+DF23, the configuration of PC+DF22 or the configuration of PC+DF23 Wait. In addition, the base material of the internal light distribution mirror in this embodiment ...

Embodiment 2

[0047] refer to Image 6 , Image 6 The light distribution method in is reflective. Through the reflector composed of 8 individual reflective surfaces such as a~h, the total reflected light is irradiated on the inner light distribution mirror with discrete materials on the large curved surface, and the large curved surface The surface of the inner light distribution mirror presents a continuous and uniform lighting effect. The base material of the inner light distribution mirror is PMMA or PC material, and the discrete material can be DF22 or DF23. It can be understood that if the discrete material is configured in the base material of the inner light distribution mirror, it can be configured in various combinations, such as the configuration of PMMA+DF22, the configuration of PMMA+DF23, the configuration of PC+DF22 or the configuration of PC+DF23 Wait. It can be understood that, as other modification schemes, a separate texture treatment can be performed on the surface of ...

Embodiment 3

[0049] refer to Figure 7 , Figure 7 The light distribution method is direct type. In this embodiment, there is no reflector. Multiple groups of LED lamps are combined to form a direct light source array. The lighting effect of the insulation. According to the characteristics of the large curved surface, the arrangement of multiple LEDs can be evenly distributed according to the size of the curved surface.

[0050] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0051] 1. The light distribution scheme of the present invention is adopted, that is, a new type of scattering material with discrete materials is used as the inner light distribution mirror, so that the output light can be scattered more evenly (such as figure 2 As shown), it can effectively weaken and eliminate the bright and dark areas formed on the surface of the inner light distribution mirror after lighting, so that the illumination is uniform and beautiful, and...

Abstract

The invention discloses a light distribution method of a vehicle brake lamp. The light distribution method of the vehicle brake lamp is characterized by comprising an LED light source and an inner light distribution mirror; a discrete material is arranged in a substrate of the inner light distribution mirror; and emitted light of the LED light source is emitted out after passing through the inner light distribution mirror. The light distribution method is adopted; and the novel discrete material is used as an auxiliary material of the inner light distribution mirror, so that output light rays are scattered more uniformly, bright and dark areas formed on the surface of the inner light distribution mirror after lightening can be effectively weakened and eliminated, the illumination is uniform and beautiful, and the internal structure and light source selection is wider and more various.

Description

Technical field: [0001] The invention relates to the field of automobile lighting fixtures, and more specifically, to a light distribution method for automobile brake lamps. Background technique: [0002] The development of China's automobile industry has reached a new stage. With the popularization of automobiles and the increase of consumer groups, all walks of life have more and more stringent requirements for automobile styling, especially in the shape of car lights. The design structure of various styles of car lights It plays a decisive role in the influence of light shape. Taking brake lights as an example, due to the structural characteristics of the internal reflector, lamps with internal light distribution mirrors made of ordinary bright red materials will form bright spots or dark areas when they are lit. [0003] At present, the research and development of various automotive lighting fixtures by various automotive lighting manufacturers is the top priority. Wheth...
