Problems solved by technology

Heat dissipation is also very important for LED lamps. Traditional heat sinks are ordinary fin-type passive heat dissipation. Passive heat dissipation mainly depends on the contact area. The larger the contact area, the better the heat dissipation effect. Therefore, in order to achieve the heat dissipation effect of traditional high-power LEDs, radiator They are all very large, resulting in a huge volume of the entire lamp, super heavy weight, and inconvenient use

Abstract

The invention discloses an illumination lamp and a preparation method thereof. The illumination lamp comprises an LED light-emitting integration light source and a microgroove group phase-change fin radiator. The LED light-emitting integration light source comprises LED light sources and a radiator temperature equalization panel. The LED light sources are arranged on one face of the radiator temperature equalization panel. The microgroove group phase-change fin radiator comprises phase-change liquid, a cavity and a plurality of radiating fins. The cavity is provided with an opening. The other face, opposite to the LED light sources, of the radiator temperature equalization panel seals the opening. The multiple radiating fins are arranged on the outer cavity wall of the cavity. The radiating fins are provided with a plurality of microgroove groups. The phase-change liquid is contained in the cavity. The illumination lamp has the characteristics of photo-thermal integration and high power, the heat conduction and heat dissipation speed is high, the luminous flux is stable and the service life is long. By the adoption of the preparation method, connection between an LED module and the radiator is simplified, and thermal resistance is lowered.

Description

technical field [0001] The invention relates to a lighting fixture and a preparation method thereof, belonging to the field of LEDs. Background technique [0002] LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. When the LED emits light, part of the energy will be converted into heat, which will increase the temperature of the LED chip. The temperature has a great impact on the working performance of the LED chip. High temperature will greatly reduce the light output efficiency of the chip, accelerate the aging of the chip, and shorten the life of the device. Therefore, in order to ensure the normal operation of the LED, the heat emitted by it must be exported and dissipated quickly in time. The heat sink structure of traditional high-power LED lamps is the way that the LED light source is mounted on the bottom of the finned heat...
