Liquid-cooling heat dissipation LED lamp

Abstract

The invention provides a liquid-cooling heat dissipation LED lamp which comprises a lamp holder and a lampshade. The lamp holder comprises a radiator and a lamp cap connected to one end of the radiator through a connecting piece. An LED base plate is connected to the lamp holder. The lampshade is connected to one end of the lamp holder. The lampshade comprises an inner lampshade body and an outer lampshade body which are in two layers, and a liquid storage cavity where cooling liquid is poured is formed between the two lampshade bodies. A heat conduction part connected with the lamp holder in a heat conduction manner is attached to the outer surface of the side wall of the inner lampshade body and is soaked in the cooling liquid. The lamp holder is in threaded connection with the lampshade, and the inner lampshade body and the outer lampshade body are connected with the lamp holder. An expansion ring is embedded between an inner connecting ring and an outer connecting ring and is tightly attached to the bottom face of an annular groove. A bar-shaped groove matched with the heat conduction part is formed in the inner wall of the expansion ring. By means of the LED lamp, the cooling liquid is used for heat dissipation, the cooling effect is good, the radiation range is large, the service life of the LED lamp can be better and effectively prolonged, the volume of the liquid storage cavity is slightly adjusted through the expansion ring, and safety of the LED lamp is facilitated.

Description

technical field [0001] The invention belongs to the technical field of lighting fixtures, and in particular relates to a liquid-cooled and heat-dissipating LED lamp. Background technique [0002] LED is the abbreviation of light emitting diode in English. Its basic structure is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver or gold wires. , and then sealed with epoxy resin around to protect the inner core wire, and finally install the shell, so the LED lamp has good shock resistance. The field of application involves mobile phones, table lamps, home appliances and other daily household appliances and machinery production. [0003] Heat dissipation has an important impact on the service life of LED lights. Traditional LED lights use many large-sized fins to dissipate heat. Due to their large size and high cost, they have been gradually replaced by me...

Problems solved by technology

Aiming at the shortcomings of the existing single-layer lampshade combined with metal wires, which have uneven heat transfer, limited heat dissipation efficiency, and no obvious effect on prolonging the service life of LEDs, this invention provides a double-layer lampshade liquid-cooled and heat-dissipating LED lamp, which includes a lamp holder and The lampshade, the lamp holder is connected with the LED substrate, and the lampshade is connected to one end of the lamp holder. The lampshade includes a double-layer inner cover and an outer cover, and a liquid storage chamber filled with cooling liquid is formed between the two lamp shades. The side wall of the inner cover The outer surface is covered with a heat conduction member connected to the heat conduction of the lamp holder
