| description | The utility model relates to a laser light supply apparatus used for a projection display device, which comprises a green light laser, one or a plurality of red light semiconductor laser(s), one or a plurality of blue light semiconductor laser(s) and a beam combining device, wherein the beams outputted by the green light laser, one or the plurality of red light semiconductor laser(s), and one or the plurality of blue light semiconductor laser(s) are combined into a beam of parallel lights and outputted through the beam combining device. The laser light supply apparatus overcomes the defects of high cost and serious speckle, and the like of large power red light and blue light lasers in the current projection laser light supply, and realizes a low-cost red-green-blue three-basic color light supply module. Both the radiating performance and stability of the light supply module are greatly improved; and the light supply module has very high application values. |
