Abstract

The invention discloses a large-power LED lamp based on compound phase-change energy storing material radiating. The large-power LED lamp comprises a reflecting cup, a large-power LED light source arranged at the bottom part of the reflecting cup, and a light transmission plate which is formed by a PC plate or an organic glass plate and is fixed to the front end of the reflecting cup through a mounting ring; a compound phase-change energy storing radiating body which is peripherally equipped with radiating aluminum fins is connected to the rear end of the reflecting cup; a compound phase-change material container of which one end is opened is formed in the middle part of the compound phase-change energy storing radiator; compound phase-change materials fill in the compound phase-change material container; a radiator top cover for sealing is arranged at the opening end of the compound phase-change material container through a screw. With the adoption of the large-power LED lamp based on the compound phase-change energy storing material radiating, the shortages of the existing radiating technology of large-power LED down lamps can be overcome; the LED lamp has a good radiating effect, and is influenced a little by the periodic high-density heat flow, simple in structure, long in service life, convenient to mount, and low in cost.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to a high-power LED lamp for heat dissipation based on a composite phase-change energy storage material. Background technique [0002] LED lighting refers to solid-state lighting that uses a semiconductor light emitting diode (Light Emitting Diode—LED) as a light source. It has obvious advantages such as green environmental protection, energy saving and high efficiency, long life, small size, and quick response. Compared with traditional incandescent lamps, it can save 60% to 90% of electric energy. One of the high-tech fields with development prospects. However, due to the low photoelectric conversion efficiency of high-power LEDs and the vulnerability to periodic high-density heat flow, LED lighting products have not yet been able to adapt to the increasingly competitive lighting market. Therefore, how to solve the high-density heat flow of LED chips while improving the packaging densit...
