Problems solved by technology

[0004] However, in the LED strip lamps of the prior art, the LED substrate is directly immersed in the heat dissipation liquid, and the heat generated when the LED light source 1 in the LED lamp emits blue light and the heat generated by converting the blue light into white light is mainly transferred to the heat sink through the LED substrate. The liquid dissipates, the heat dissipation method is single, and the heat dissipation effect is not ideal
[0005] In addition, because the heat dissipation liquid is generally corrosive to a certain extent, the LED substrate and the chips on the LED substrate soaked in the heat dissipation liquid are easily corroded, which affects the life of the LED lamp.

Abstract

The invention provides an LED (Light-Emitting Diode) lamp. An LED substrate and an LED light source of the lamp are sealed in a first sealing cavity formed by the inner surface of an inner seal cover and the top of the substrate, heat dissipation liquid is filled in a second seal cavity formed by the inner surface of an outer light distribution cover, the outer surface of a substrate seat and the outer surface of the inner seal cover, and the inner seal cover, the outer light distribution cover or the heat dissipation liquid is provided with fluorescent powder. Heat generated by light emitting due to PN junction excitation is quickly transferred to the heat dissipation liquid through the substrate in tight connection with the LED substrate, light emitted by the PN junction excitation is directly transferred to the heat dissipation liquid through heat generated by required light transformed by fluorescent powder, and through the convection of the heat dissipation liquid, heat is transferred to the light distribution cover to achieve the heat dissipation effect. The heat generated when the LED lamp is in operation is dissipated through two ways, so that the heat dissipation effect is improved, and the service life of the LED lamp is favorable for being prolonged.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a liquid-cooled light-emitting diode lamp. Background technique [0002] LED (Light Emitting Diode, light emitting diode) is a semiconductor device that can directly convert electricity into visible light. LED lighting has the advantages of energy saving and environmental protection, and has become a major trend in the development of the lighting industry. However, the operating temperature of the LED directly affects the life of the LED. The lower the temperature, the longer the life, which makes the heat dissipation design of the LED lamp very important. Taking white LED lamps used in lighting as an example, the heat generated by LED lamps mainly comes from two aspects: the heat generated when the PN junction excites blue light; the heat generated by the conversion of blue light into white light through phosphor powder. [0003] The structural diagram of LED strip lamps in the p...
