Abstract

A liquid-cooled LED (light-emitting diode) lamp comprises a lampshade, a light source component and a radiating device. The lampshade covers a radiator and encloses a sealed space, the light source component is contained in the sealed space, the radiating device comprises a heat conductor, a radiator and radiating fins, the light source component is fixedly arranged in the heat conductor, the lampshade is connected with the radiator, the radiator is provided with a containing cavity filled with radiating liquid, the heat conductor is hermetically connected with the containing cavity, at least part of the heat conductor is inserted into the containing cavity, and the radiating fins are arranged on the radiator. As the radiating liquid is high in uniformity and heat capacity, heat generated by an LED bulb in operation can be uniformly absorbed by the radiating liquid, and damage to the LED lamp caused by incapability of dissipating a large amount of heat in a short time due to small heat capacity is avoided.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a liquid-cooled LED lamp. Background technique [0002] The rapid development of the LED industry has greatly stimulated the development of the upstream material industry and further promoted breakthroughs in the field of high-end materials. Among them, a large number of heat dissipation materials are used in LED lamps, including LED chip packaging components, LED optical lenses, light scattering components, high-efficiency heat dissipation components, light reflection and light diffusion plates, etc. [0003] Heat dissipation is a major factor affecting the lighting intensity of LED lamps. LED lamps are 80% more energy efficient than traditional incandescent lamps, but their LED components and driver circuits dissipate a lot of heat. If the heat is not properly discharged, the luminosity and life of LED lamps will drop sharply. For a long time, poor heat dissipation ...
