Embodiment Construction
[0031] The following will clearly and completely describe the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0032] The laser has a small divergence angle and high power, which can achieve high brightness even at a long distance. In particular, it will be widely used in automotive lights, lighthouse indicators, mine headlights, portable lighting and other fields.
[0033] In recent years, the application of laser light sources in projection, searchlight and other fields has become more and more extensive. As a new generation of light sources, lasers are gradually replacing LEDs an...

The invention discloses a laser light source device, and the device comprises a blue laser which is used for emitting blue laser; a fluorescent wheel which is provided with a red fluorescent area, a blue fluorescent area and a green fluorescent area; the red fluorescence region is excited by the blue laser to emit red fluorescence; the green fluorescence region is excited by the blue laser to emitgreen fluorescence; the blue light area can reflect the blue laser; a red and green laser set which emits red laser when the red fluorescence area rotates to the position above the red fluorescence area, and emits green laser when the green fluorescence area rotates to the position above the green fluorescence area; and a beam combining and collimating assembly which is used for coupling and collimating the fluorescent light and the laser emitted by the fluorescent wheel to form parallel light to be emitted. By applying the laser light source device provided by the invention, the equipment size can be effectively reduced, and the integration level is improved.
Description
technical field [0001] The invention relates to the technical field of laser applications, and more specifically, to a laser light source device. Background technique [0002] Laser has the characteristics of high brightness, small wavelength width, and small etendue, and has broad application prospects in the field of laser display and laser lighting. [0003] In recent years, the application of laser light sources in projection, searchlight and other fields has become more and more extensive. As a new generation of light sources, lasers are gradually replacing LEDs and light bulbs in various fields. [0004] At present, the optical path structure of high-brightness laser light sources on the market is simple, and the equipment is often bulky, while the bulb is often small in size, but the laser cannot be directly used to replace the traditional bulb, and can only be transmitted by means of optical fiber. Therefore, it is always the development direction of miniaturization...
