Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
Example 1:
referring to fig. 1, a laser lighting device is shown.
The laser lighting device comprises a heat dissipation substrate 1, fluorescent ceramic 2, a reflecting bowl 3, a semiconductor laser 4, a reflector 5 and the like.
The heat-dissipating substrate 1 is used for heat conduction and/or heat equalization. The front of the heat dissipation substrate 1 is provided with fluorescent ceramics 2, a reflecting bowl 3 and a semiconductor laser 4.
The reflecting bowl 3 surrounds the periphery of the fluorescent ceramic 2. The reflecting bowl 3 is big in front and small in back. The fluorescent ceramic 2 is arranged at the focal position of the light reflecting bowl 3. The inner surface of the reflecting bowl 3 is a mirror surface, a sand surface or a scaly nail surface and other reflecting surfaces.
The semiconductor laser 4 is arranged on the periphery of the light reflecting bowl 3. The emitting direction of the semiconductor laser 4 and the normal direction of the fluorescent ceramic 2 are both arranged forward.
A reflective mirror 5 is disposed in front of the semiconductor laser 4. The reflector 5 is used for reflecting the emergent light beam of the semiconductor laser 4 to the fluorescent ceramic 2.
The working principle is as follows: the outgoing beam of the semiconductor laser 4 is reflected to the fluorescent ceramic 2 via the mirror 5. The emergent light beam is excited with the fluorescent ceramic 2 to generate an excitation light beam (the semiconductor laser 4 is blue light, and the excitation light beam is white light). The excitation beam is projected from the fluorescent ceramic 2 to the reflector 3, collected and distributed.
Therefore, the laser lighting device has a simple and compact structure, and can effectively realize the light distribution design of a laser lighting area.

On the basis of embodiment 1 (the laser lighting device includes a heat-dissipating substrate 1, a semiconductor laser 4, a fluorescent ceramic 2, a reflector 3, and a reflector 5), a convex lens 6 is accommodated in the reflector 3. The convex lens 6 is arranged in front of the fluorescent ceramic 2. The convex lens 6 converges and collects the excitation light beam from the fluorescent ceramic 2 to the middle position of the whole light spot, so that the efficiency and the light spot effect of the white light distribution system can be improved.
