LIGHT- COMBINING AND COLLIMATING DEVICE |
摘要 |
A light-emitting device (100) comprising four light sources (101, 102, 103, 104) in quadrangular arrangement, and a collimating element (110) arranged to collimate and mix light emitted by said light sources is provided. The collimating element has a receiving side (111) for receiving light from said light sources and an opposite output side (112), and comprises two intersecting V-shaped profile surfaces (120, 130), the edges of said V-shaped profile surfaces (125, 135) being arranged towards said receiving face (111). The collimating element is capable of collimating the light from the four light sources and obtain a good color mixing, such that light from each light source is collimated to essentially the same degree. |
