Abstract

The invention relates to a light source system and application thereof. The light source system comprises a laser, an interference filter, a first condenser lens, a light conversion device, a reflector, a second condenser lens, a dodging member, a radiating member and an actuator. The light conversion device comprises a transparent substrate, a wavelength conversion layer and a filter layer; the transparent substrate is rotatable; the filter layer is laminated on the transparent substrate and the filter layer is set around the edge of the transparent substrate for a round to form an annular structure; the wavelength conversion layer is laminated on the transparent substrate and the wavelength conversion layer is set in the middle of the transparent substrate; the radiating member is fixedly connected with the transparent substrate at the side far from the wavelength conversion layer; the actuator and the radiating member are fixedly connected; and the actuator can drive the transparent substrate to rotate through the radiating member. The projection system has the advantages of good heat radiation performance, therefore, the heat effect of the light conversion device in the fluorescence transition process can be improved, and the brightness of the light source system can be raised.

Description

technical field [0001] The invention relates to the lighting field, in particular to a light source system and its application. Background technique [0002] At present, projectors are widely used in various applications such as movie playback, conferences, and publicity. As we all know, in the light source of a projector, a fluorescent color wheel is usually used to provide a sequence of colored light. Moreover, the current projectors generally use a fluorescent conversion projection light source system. This light source system generally needs to use a high-power-density laser to emit excitation light to excite the fluorescent color wheel to emit fluorescence. However, due to the high power of the laser, the heat generated is large. And the higher the power, the greater the heat, so that the light source system will generate a lot of heat during the fluorescent conversion process, while the traditional light source system has poor heat dissipation performance, and the hea...

Problems solved by technology

Moreover, the current projectors generally use a fluorescent conversion projection light source system. This light source system generally needs to use a high-power-density laser to emit excitation light to excite the fluorescent color wheel to emit fluorescence. However, due to the high power of the laser, the heat generated is large. And the higher the power, the greater the heat, so that the light source system will generate a lot of heat during the fluorescent conversion process, while the traditional light source system has poor heat dissipation performance, and the heat during the fluorescent conversion process cannot be dissipated in time, resulting in the generation of fluorescent color wheel. Severe thermal effects make it difficult to increase the brightness of the light source system
