Embodiment Construction

[0018] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0019] Such as Figure 1-2 As shown, this embodiment provides a light strip system that realizes large-area uniform light emission, including a light guide strip 1, a reflector 3 and an inner light-transmitting mirror 4, and the light guide strip 1 is located between the reflector 3 and the inner light-transmitting mirror 4. In the middle of the mirror 4, the light guide strip 1 is provided with two tooth-shaped optical patterns, that is, the first optical pattern 2a and the second optical pattern 2b. The tooth-shaped optical pattern 1 2a and the tooth-shaped optical pattern 2 2b are respectively Structure surface 1 5 and structure surface 2 6 are provided, and the included angle α and an...

Abstract

The invention provides a lamp strip system capable of achieving the large-area uniform light-emitting function. The lamp strip system comprises a light guide strip, a reflector and an inner light-transmitting mirror. The light guide strip is positioned between the reflector and the inner light-transmitting mirror. The light guide strip is provided with two sections of toothed optical patterns, namely an optical pattern I and an optical pattern II. By designing the light guide strip with the tooth-shaped optical patterns in multiple directions, the light guide strip not only can be used for punching bright patterns in front of the light guide and ensuring uniformity, but also can be used for punching side edges or large-visual-angle patterns. Therefore, the uniformity of a whole optical system is ensured. Tooth-shaped optical patterns and orientations of the tooth-shaped optical patterns on the light guide strip are additionally designed. Through diffuse reflection of the reflector andthe inner light distribution mirror made of the emulsifying material, the single light guide strip is formed. The irradiation range is wide, and the lighting effect is uniform. The consistent and goodlight-emitting effect can be kept at all angles. The LED lamp has the advantages of being small in number of LED light sources, low in cost and uniform in light-emitting.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to a light strip system for realizing uniform light emission in a large area. Background technique [0002] The automobile industry has matured through nearly 40 years of development, and the popularity of automobiles among consumers has gradually increased. When consumers have a certain spending power, often a car's fashion, sense of technology, handling, etc. can influence consumers' right to choose. In recent years, the high sales volume brought by the high-quality cars has become more and more obvious. The lighting effect of functions such as taillights that are always on at night (all day in European law) has become a top priority. As the price war of cars in the current market is still fierce, in this complicated environment, car manufacturers have put forward double standards for the price and lighting effect of car lights. At present, the uniform light strip system reali...
