A heat sink for an adjustable focus LED projection lamp

Abstract

The invention discloses a focusable LED projection lamp radiator. The focusable LED projection lamp radiator comprises a heat conducting plate, and is characterized in that heat dissipating pieces are annularly arranged on the surface of the heat conducting plate; a cooling fan for penetrating through the heat conducting plate is arranged among the heat dissipating pieces; a cooling liquid device is arranged on the surface of the other side of the heat conducting plate; a semiconductor refrigerating piece is arranged under a liquid cooling device; a silicon grease layer is arranged on the semiconductor refrigerating piece, and is connected with the liquid cooling device; and the liquid cooling device is connected with one end, penetrating through the heat conducting plate, of the cooling fan. The focusable LED projection lamp radiator can quickly absorb and dissipate heat generated by an LED lamp through cooling of the heat dissipating pieces by the cooling fan and acceleration of liquid flowing of the liquid cooling device by a rotating rod, and is high in cooling efficiency, excellent in cooling effect, simple in operation and high in practicability.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a radiator for an adjustable focus LED projection lamp. Background technique [0002] The basic structure of the LED lamp is a piece of electroluminescent semiconductor material, which is placed on a shelf with leads, and then sealed with epoxy resin around it to protect the inner core wire. When using a higher-power LED lamp, it usually requires Use radiators to dissipate heat from LED lights. Existing radiators are mainly composed of separate heat sinks. A slightly more complex radiator will dissipate heat through a fan. Such radiators have a single cooling method, poor effect, and low heat dissipation efficiency. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a heat sink for an adjustable focus LED projection lamp, which has various heat dissipation methods, and multiple heat...
