Abstract
The utility model discloses an LED (Light-Emitting Diode) lamp capable of effectively radiating. The lamp comprises a lamp cover, wherein an aluminum base plate is arranged in the lamp cover, and LED lamp bulbs with large power are laid on the aluminum base plate; an energy storage plate which is tightly adhered to the aluminum base plate is arranged at the position of a port of the lamp cover; the energy storage plate is provided with a straight-line heat conduction pipe which passes through the energy storage plate and is vertical with the lamp cover; and a plurality of radiation sheets are inserted into both ends of the straight-line heat conduction pipe. As the heat conduction pipe is a copper column, the heat conduction pipe is good in heat transmission property and the heat can be rapidly transmitted from one end to the other end; therefore, an optimal heat transmission process is realized by filling a refrigerant fluid into the heat conduction pipe. In the transmission process, not only the heat is transmitted through metal but also the refrigerant fluid in the copper pipe is used as a heat transmission medium. The thermal conductivity of the refrigerant fluid is approximately 200 times as great as that of copper. The heat emitted the LED lamp bulbs is rapidly transmitted from the energy storage plate to the straight-line heat conduction pipe and is radiated with the help of the radiation sheets, thereby achieving effects of the rapid heat radiation and low-temperature maintenance of the LED lamp bulbs.
