Abstract

The invention relates to a heat radiating system used in high-power light emitting diode, wherein it comprises liquid-cold radiator and controller; said radiator is formed by liquid cooling head, cooling tower, duct, cooling liquid tank, and water pump at the bottom of diode; the duct connects the cooling head, cooling tower, cooling liquid tank, and water pump; the water pump is connected to one motor; the controller is connected to motor to control ist operation; when the bottom temperature T of diode is higher than tH, motor works until the temperature T is lower tL; the values of tH and tL are set in controller.

Description

technical field [0001] The invention relates to a heat dissipation system suitable for high-power light-emitting diodes, in particular to a heat dissipation system of light-emitting diodes with good heat dissipation effect. Background technique [0002] At present, the heat dissipation problem of high-power light-emitting diodes (hereinafter referred to as LEDs) for lighting has always been the most troublesome matter in the industry. The solution is to increase the area of ​​the heat dissipation substrate, or to improve the shape of the heat dissipation substrate and use better heat dissipation materials. Such as Chinese Patent No. 200420034088.0, this patent discloses a LED heat dissipation structure, that is, a metal sheet is placed inside the lamp body. Obviously, this heat dissipation method is far from enough for the heat dissipation requirements of high-power light-emitting diodes. . Contents of the invention [0003] In order to overcome the above defects, the obj...
