AI Technical Summary
Existing LED light sources in automotive lighting applications have a small light direction angle, which requires increasing the light-emitting area to meet design requirements. At the same time, traditional light sources have issues with lifespan and power consumption.
Design a lighting module and device in which a light source is sealed in a resin layer. The light-emitting device of the light source has different sizes and optical pattern areas. By setting LED chips of different lengths and numbers, the overlap of optical patterns and the difference in aperture of the reflective layer are achieved to optimize the light distribution.
It achieves uniform illumination in a narrower edge area, suppresses hot spots in the resin layer area, and improves the reliability of the lighting device and the uniformity of the optical pattern.
