Motor vehicle signal lamp capable of presenting three-dimensional lighting effect

Abstract

A motor vehicle signal lamp capable of presenting a three-dimensional lighting effect comprises a lamp body, a circuit board and an LED light source which are arranged in the lamp body, and a lens arranged at the front end of the lamp body, and the inner surface and the outer surface of the lens are both designed to be optical reflecting surfaces formed by connecting N cutting planes with random cutting angles. The bright lighting effect can be achieved through the optical surface form of the two random patterns, and the monotonicity of the light emitting form of an existing signal lamp is made up. The requirement for LED positioning is not high, and the lighting effect of different light colors in the same area can be achieved. The effect is dazzling when the light distribution mirror islightened, and even if the signal lamp is in a non-lightened state, sunlight shines on the pattern surface of the light distribution mirror, and due to the special pattern cutting surface, the signallamp can sparkle like a diamond. In addition, in the lighting state, different lighting effects can be observed along with the difference of observation angles.

Description

technical field [0001] The invention relates to a car lamp, in particular to a motor vehicle signal lamp capable of presenting a three-dimensional lighting effect. Background technique [0002] After LED signal lights are applied to car lights, they have gradually evolved into a variety of different lighting forms: including reflector type, thick-walled type, light guide type, etc. With the maturity of technology, there is little difference in the optical form of signal lights from high-end cars to economical cars. In order to pursue unique and stylish lighting effects of signal lights, many high-end models put forward new design requirements for car light design manufacturers. [0003] At present, the main design features of the widely used light-emitting forms of car lights are: uniform light-emitting area. However, the existing signal light has the defect of monotony, and has high requirements on the positioning of LEDs, so it is impossible to realize the lighting effec...
