Abstract

The invention relates to a lighting device, in particular to an LED (Light Emitting Device) light capable of generating electricity by self and actively radiating heat. A large-power LED is used as a light source. The LED light comprises a casing provided with an inner cavity, wherein an LED base plate is arranged in the middle of the inner cavity of the casing, an LED bulb is arranged on the front side of the LED base plate, and a transparent cover is arranged below the LED bulb; an air inlet and an air outlet are respectively formed in the rear part and the front part of the casing, a heat radiating channel is arranged between the air inlet and the air outlet, and a heat radiating fan is arranged in the heat radiating channel; the back of the LED base plate is connected with a semi-conductor thermo-electric generating chip, the low temperature side of the semi-conductor thermo-electric generating chip is connected with a heat radiator provided with heat radiating fins, and the heat radiator is arranged in the heat radiating channel; and a power supply lead of the heat radiating fan is connected with the semi-conductor thermo-electric generating chip. The LED light has the advantages of simple structure, excellent heat radiating effect, convenience in manufacture and installation and low cost.

Description

Technical field [0001] The invention relates to a lighting device, in particular to a self-generation active heat dissipation LED lamp using high-power LED as a light source. Background technique [0002] Since LEDs are electronic components, heat dissipation has always restricted the development and application of high-power LEDs. As the power of a single LED increases (above 1W), the conversion efficiency of the LED decreases and the heat generation increases. However, there are basically no practical products in China for high-temperature-resistant LED chips and phosphors, and high-performance products are expensive and not suitable Popularize and use in a large area. The current domestic practice is to use a large number of 1W LED lamp beads in series to achieve the required luminous flux, or use the rated 5W LED lamp beads to reduce the power to 3W, which can significantly reduce the heat. But this approach requires a lot of raw materials and labor. The integrated high-po...
