LED lighting device capable of recovery heat

Abstract

The invention discloses a LED illuminating device capable of heat recovery, comprising an LED flat panel light source, a heat-dissipation device and a thermoelectricity conversion device; the heat-dissipation device comprises a closed box-shaped inner base plate, a heat pipe radiator and a cooling fan which is positioned above the heat pipe radiator; the backside of the LED flat panel light source is closely attached on lower surface of the inner base plate and the heat pipe radiator is closely attached on upper surface of the inner base plate; the thermoelectricity conversion device comprises a plurality of outer base plates which are arranged around the outside of the inner base plate and heat dissipation fins are arranged on outer lateral surfaces of each outer base plate; sheet-type thermoelectricity converters are arranged between inner lateral side of each outer base plate and outer lateral side of each inner base plate, the side where the thermoelectricity converter is closely attached on the outside is heat end and the side where the thermoelectricity converter is closely attached on the inner side is cold end; the heat end and cold end of each thermoelectricity converter are series-connected, parallel-connected or series-parallel connected and then are connected via output wires with an energy-storage conversion unit arranged at one side of a radiator; the energy storage conversion unit can distribute electric energy to LED flat panel light source for auxiliary lightening and can drive the operation of cooling fan.

Description

technical field [0001] The invention relates to an LED lighting device capable of realizing heat recovery. Background technique [0002] Compared with other light sources, LED [light-emitting diode] lighting has the advantages of high luminous intensity, energy saving and energy saving. It has developed rapidly in recent years, and the industrial scale has continued to expand. However, with the market's demand for high-power LED lighting devices, the problem of LED heat dissipation has become a bottleneck restricting the development of the industry. [0003] At present, LED lights on the market mainly rely on natural heat dissipation. From the perspective of heat transfer, natural heat dissipation uses natural convection and thermal radiation as the basic heat dissipation principles. In natural heat dissipation, the basic idea is to use the outer wall of the lamp, especially the fins to convect the surrounding air and radiate heat to the surrounding objects. This form of h...
