Description

technical field [0001] The invention relates to the technical field of vehicle lamps, in particular, to a dual-function multiplexed thick-walled optical system and a vehicle lamp following modeling. Background technique [0002] In the past, the thick-walled part system needs to realize the multiplexing of two functions. In most cases, two different LEDs use the same light entry system. Considering the actual PCB circuit design and the influence of the heat dissipation performance of the LED itself on the working condition of the LED , the distance between the LEDs should not be too small, and both LEDs need to be placed out of focus, that is, they are not on the optical focus of the light entry system design, so the light utilization efficiency of each LED is not high, because the light of the LED passes through the entrance.

Problems solved by technology

[0002] In the past, the thick-walled parts system had to achieve two functions multiplexing. In most cases, two different LEDs used the same light input system. Considering the actual PCB circuit design and the influence of the heat dissipation performance of the LED itself on the working conditions of the LED , the distance between the LEDs should not be too small, the two LEDs need to be placed out of focus, that is, they are not at the optical focus when the light entering system is designed, so that the light utilization efficiency of each LED is not high, because the light of the LED passes through the entering After the optical system, the light is not completely parallel in the thick-walled parts, and the defocused LEDs have uneven lighting effects when lighting up the thick-walled parts

[0003] The improved technology of the existing technology is to reuse two functions in one area, and use two paraboloids to perform two functions. However, when the light emitted by the parabola enters the second parabola, the light will converge twice. The lighting effect on the final lighting surface will be uneven, and there will be bright spots with bright spots in the middle and dark spots on both sides. The uniformity will be greatly affected, and the paraboloid is a whole, so it is not easy to control the light pattern, precision and flexibility as a whole. Low

[0004] In addition, the existing technology, including the above-mentioned parabolic surface multiplexing system, cannot achieve a conformal and highly flexible design. In fact, the current development trend of car lights is that the shape is becoming more and more narrow, complex, inclined, and large-angle. , if the existing technology needs to deal with various complex shapes, there must be problems in the design of the optical path in order to meet the light energy emitted along the shape surface to the direction of the test position, so that the optical path design cannot be guaranteed to be similar or the same, resulting in defects in optical effects. In addition, the size of the optical unit of the optical system It will inevitably increase, which will not only lead to parts size and cost problems, but also bring great difficulties to the increasingly narrow space of car lights, such as assembly difficulty, the adjustment range of the adjustment system will be limited and interfere with other parts, and thermal problems Difficult to alleviate, etc., when multi-functional functions are required, this problem will be multiplied, which will bring great difficulties to the design of car lights
