Abstract

A high-power liquid radiating LED lamp which is provided with a radiating column (4) and heat transfer oil (8). The radiating column and the heat transfer oil are in direct contact with a copper-clad layer (14) of an LED (2) and a radiating plate (3). Most of the heat of a PN junction (9) is directly transferred to the radiating plate through the copper-clad layer, the radiating column and the heat transfer oil of the radiating column. Because most of the heat of the PN junction is not transferred to the radiating plate through an insulating layer (15) and the heat transfer coefficients of the radiating column and the heat transfer oil are greater than the heat transfer coefficient of the insulating layer, the heat dissipation effect of the LED is increased. Meanwhile, the insulation resistance of the radiating column and the heat transfer oil is greater than or equal to the insulation resistance of the insulating layer, thereby ensuring the insulation requirement between the copper-clad layer and an aluminium substrate.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a high-power liquid heat dissipation LED lamp. Background technique [0002] In existing high-power LED lamps, an insulating layer is provided between the copper-clad layer of the LED lamp and the aluminum substrate. Due to the low thermal conductivity of the insulating layer, it hinders the dissipation of heat from the PN junction of the LED lamp and reduces the heat dissipation of the LED lamp. The effect affects the service life of the LED lamp. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a high-power liquid heat dissipation LED lamp, which is used to improve the thermal conductivity of the insulating layer of the LED lamp and improve the heat dissipation effect of the LED lamp. [0004] The technical scheme adopted in the present invention is: a high-power liquid heat dissipation LED lamp includes a brac...
