High color rendering index laser white light acquiring device and implementation method thereof

Abstract

The invention relates to a high color rendering index laser white light acquiring device which comprises a light source transmitting device and a light conversion medium, wherein the light conversionmedium faces the light source emitting end of the light source transmitting device, and the set distance is kept between the light conversion medium and the light source transmitting device. The lightsource transmitting device comprises a blue laser transmitting device and a red light source transmitting device, the light conversion medium can absorb an incident light source transmitted by the light source transmitting device, and high color rendering index laser white light with needed color temperature is acquired. The device overcomes the shortcomings that according to an existing high color rendering index laser white light acquiring device, the light conversion medium is excited, a back is used for irradiating, and a front is used emitting light, so that the high color rendering index laser white light is poor in light source quality and brightness. The device has the advantages of uniformity, good brightness and excellent quality of the high color rendering index laser white light.

Description

technical field [0001] The invention relates to a high color rendering index laser white light obtaining device and a realization method thereof, which are applied in the lighting field. Background technique [0002] Existing high color rendering index laser white light acquisition equipment is generally irradiated on the side facing away from the light exit surface of the light conversion medium to excite the light conversion medium, and the high color rendering index laser white light with the required color temperature is obtained by the light conversion medium. The front side (that is, the light exit surface) exits. However, since the light intensity of the laser is much stronger than that of ordinary light beams, and the light spots are relatively concentrated, it is easy to cause uneven color and poor brightness at the edge of the high color rendering index laser white light (exit light source), which affects the high color rendering index. The quality of the light so...
