Abstract
A light source (210, 310) for a reflection luminaire, a reflection luminaire (200, 300) for an automobile and an automotive headlamp comprising the reflection luminaire (200, 300) are disclosed. The light source (210, 310) comprises a substrate (212), and a light emitting component (214), being a Chip Scale Package light emitting diode, and a light absorbing component (216) on the substrate (212). The light absorbing component (216) is configured to absorb light which is emitted from a side surface of the light emitting component (214) and incident on a surface of the substrate (212). The light source facilitates reducing or eliminating glare of a CSP LED reflection luminaire for an automobile.
