Embodiment Construction

[0045] 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.

[0046] refer to figure 1 and figure 2 , figure 1 is a light path diagram of a traditional light source device, figure 2 for figure 1 Schematic diagram of the structure of element 3. like figure 1 As shown, light sources 1-1 to 1-4 are RGB laser light sources. The light sources are coupled and shaped inside the light source module. The output light here is parallel light. The number of light sources can be increased or decreased according to actual needs, and the wave...

Abstract

The invention provides a light source device, display equipment and a lighting device, and the light source device comprises a first light source assembly used for emitting a laser beam; a second light source assembly used for emitting wide-spectrum fluorescence; a coupling assembly used for coupling the laser beam and the wide-spectrum fluorescence into a first light beam; a first converging assembly used for converging the first light beam into a second light beam; an optical bar used for carrying out shimming shaping processing on the second light beam. The coupling assembly is located between the first light source assembly and the first convergence assembly; the coupling assembly is provided with a light-transmitting window, and the laser beam is coupled with the wide-spectrum fluorescence reflected by the coupling assembly through the light-transmitting window to form the first light beam and then enters the first converging assembly. According to the technical scheme, a special-shaped light bar is not needed, and the light energy utilization rate is increased.

Description

technical field [0001] The present invention relates to the technical field of laser application, and more specifically, relates to a light source device, a display device and an illumination 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] Laser spectroscopy has many advantages, but it has the problems of speckle and low display index, which can be solved by coupling with broad-spectrum fluorescence. In the prior art, when the laser beam is coupled with the wide-spectrum fluorescent light, part of the light waves will be wasted. Contents of the invention [0004] In view of this, the present invention provides a light source device, a display device and a lighting device, thereby improving the utilization rate of light energy. [0005] In order to achieve the above object, the present invention p...
