Abstract

An automotive lamp includes a first light source for emitting the red laser light, a second light source for emitting the green laser light, a third light source for emitting the blue laser light, a light condensing unit for collecting at least the red laser light, the green laser light and the blue laser light so as to generate the white laser light, and a light distribution unit for distributing the white laser light so as to form a predetermined light distribution pattern.

Claims

1. An automotive lamp comprising:

a first light source configured to emit a red laser light;

a second light source configured to emit a green laser light;

a third light source configured to emit a blue laser light;

a light condensing unit configured to collect at least the red laser light, the green laser light and the blue laser light so as to generate a white laser light; and

a light distribution unit configured to distribute the white laser light so as to form a predetermined light distribution pattern.
