Self-adjusting and high-heat-dissipation LED lamp

Abstract

The invention discloses a self-adjusting and high-heat-dissipation LED lamp. The lamp comprises a lamp body; the lamp body is of a cylindrical barrel structure; liquid storage tanks are symmetricallywelded and fixed to the two sides of the lamp body; a lens is fixed in the lamp body in a glued mode; a transparent film is fixed in the lamp body in a glued mode; the transparent film and the lens jointly form a cavity; grooves are symmetrically formed in the inner wall of the lamp body; sliding grooves are formed in the inner walls of the two grooves; sliding rods are fixedly welded to the interiors of the two grooves; sliding blocks are slidably connected to the sliding rods; a supporting plate is fixedly welded to the two sliding blocks jointly; and the LED lamp body is arranged on the supporting plate. The LED lamp has the advantages that when the LED lamp works for a relatively long time, a large amount of heat can be emitted, so that a calcium chromate saturated solution is separated out and the concentration of the calcium chromate saturated solution is reduced; and water in the calcium chromate solution flows into a sodium chloride solution through a semipermeable membrane, and a baffle is pushed, so that the LED lamp rises to leave a heat accumulation area on the surface of the lamp body and makes contact with a cold area on the surface of the lamp body for heat exchange.

Problems solved by technology

[0003] The heat dissipation effect of common LED energy-saving lamps is not ideal. Since the diode chip is a semiconductor, its luminous efficiency is very sensitive to temperature. As the temperature rises, the luminous efficiency of LEDs decreases rapidly. The current LED lamps need to be equipped with a large radiator , when the LED lamp is working, due to the limited heat dissipation capacity of the radiator, the energy-saving effect is limited, resulting in relatively low heat dissipation efficiency, which reduces the service life of the LED lamp and brings inconvenience to users.
