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. After the optical system, the light rays in the thick-walled parts are not completely parallel, and the LED after defocusing, when lighting the thick-...
