Heat dissipation structure of underwater LED lights

Abstract

The invention discloses a heat dissipation structure for an underwater LED lamp. The heat dissipation structure comprises a metal lamp housing, a transparent lampshade, and a bottom cover, wherein the transparent lampshade comprises an upper ring hood, a lower ring hood, a transparent sheet and a sealing ring; a base plate is arranged inside the transparent lampshade; a plurality of LED beads are arranged on the base plate; a heat dissipation plate is arranged under the base plate; a plurality of clamping grooves are formed in the lower surface of the base plate; each clamping groove is connected with the corresponding horizontal section of each L-shaped heat pipe; a metal expansion barrel is arranged inside the metal lamp housing; the vertical section of each L-shaped heat pipe penetrates through a through hole in the lower ring hood and extends into a ring cavity defined by the inner wall of the metal lamp housing and the outer wall of the metal expansion barrel; when the bottom cover is fixedly connected with the lower end of the metal lamp housing from bottom to top, the vertical sections of the L-shaped heat pipes are tightly clamped between the inner wall of the metal lamp housing and the outer wall of the metal expansion barrel. The structure disclosed by the invention fully utilizes the quick heat conducting property of the heat pipes, so as to greatly enhance the heat dissipation effect of the underground LED lamp; the heat dissipation structure is simple, and very easy to assemble, so as to greatly improve the efficiency of assembly and production.

Description

technical field [0001] The invention relates to a heat dissipation structure of an underwater lighting fixture, in particular to a heat dissipation structure of an underwater LED lamp used for a music fountain. Background technique [0002] In order to enhance the underwater lighting effect, most of the existing musical fountains are equipped with waterproof LED lamps with a sealed structure. Since there is no heat dissipation medium flowing outward in the sealed structure, the heat dissipation conditions are very poor. In addition, the visibility in the water is relatively low, and a high-power light source is required to meet the needs of the light. In this way, the heat dissipation performance requirements for underwater LED lights are even higher. up. As we all know, the temperature of the center of the LED lamp bead is very high immediately after being lit. If the heat cannot be dissipated in a short time, the life of the LED lamp will be shortened. This is a major te...
