Abstract
In this era of led-emitting-diode (LED) lighting, it is important to find a universal pattern structure for the LED automotive lamp optics. This paper starts with the secondary light distribution design method of a rippling pattern through the explanation and simulation analysis of its design principle and determines a $4^{\prime\prime}$round signal lamp scheme with good performance. It then completes the proofing verification of this scheme, and the test results achieve the original design goal. Additionally, several examples of other lamp types with the rippling pattern are introduced, including a $4^{\prime\prime}$ round halo lamp and $7^{\prime\prime}$ transit lamp.
