Liquid-cooled laser light-emitting device and making method thereof

Abstract

The invention relates to a liquid-cooled laser light-emitting device and a making method thereof. The device comprises a base, a lens, a fluorescent converter and an LD luminescent light source; the base comprises a substrate, a cavity with an opening formed in the top is fixedly formed in the top of the substrate, and a liquid inlet and a liquid outlet are formed in the two opposite ends of the side face of the cavity; the lens is sealingly stuck to the top of the cavity; the fluorescent converter is fixedly arranged on the substrate located in the cavity through a fluorescent material support body; a circuit of the LD luminescent light source is fixedly connected between the fluorescent converter and the substrate. Accordingly, lots of heat generated by work of the LD luminescent light source is directly transferred into liquid through a circuit board and a pin, the liquid actively brings the heat away, the use temperature of the LD luminescent light source is guaranteed, good heat conduction and heat dissipation capacity is achieved, the light emitting efficiency is effectively improved, the service life is effectively prolonged, the radiator size is lowered largely under the same power, high-power laser light emitting can be achieved on a small-area light source, the luminous efficiency is good, the weight is low, the cost is low, and LD laser illumination is achieved.

Problems solved by technology

LD (semiconductor laser diode) blue light has high illumination brightness and concentrated directionality. Therefore, when converting to white light, both the LD light source and the white light conversion material generate a lot of heat and the heat is very concentrated. If the heat cannot be effectively and quickly exported, it will not be possible. illumination
