Radiator for high-power LED lamp

Abstract

The invention provides a radiator for large-power LED lamps, belonging to the field of LED lamps and lanterns. The radiator comprises a cylinder ring-shaped radiating substrate and a plurality of radiating fins arranged on the substrate; a plurality of radiating fin groups are evenly distributed outside the cylinder ring-shaped radiating substrate; a radiating base installed with a large-power LED light source is arranged at the internal center of the cylinder ring-shaped radiating substrate; the radiating base and the radiating substrate are connected by a plurality of radiating ribs. In the device, the radiating area is enlarged, the radiating rate is accelerated, the requirement for radiating of the LED source is met, the service life is prolonged, the volume of the radiator is small, the manufacturing cost of the lamps and lanterns is lowered and the market competitiveness of the LED lamps and lanterns is enhanced.

Description

technical field [0001] The invention belongs to the field of LED lamps, in particular to a radiator for high-power LED lamps. Background technique [0002] LED (light emijjing diode) has the advantages of long life, high luminous efficiency, no radiation, low power consumption, etc. It is an energy-saving and environmentally friendly product; high-power LED adopts integrated packaging technology, with higher luminous efficiency, greater power, and small size, so it Power LED lamps are also emerging. [0003] Existing LED lamps mostly use multiple LED light sources to install on the heat dissipation substrate, and the heat dissipation substrate is mostly flat. Since the light source of the LED lamp requires the heat of the chip to be dissipated quickly, otherwise the LED light source will accumulate heat, making the light source Luminous decay occurs, which shortens the life of LED lamps. Using a radiator with this structure, the heat is not easy to dissipate, and the heat d...

Problems solved by technology

[0003] Existing LED lamps mostly use multiple LED light sources to install on the heat dissipation substrate, and the heat dissipation substrate is mostly flat. Since the light source of the LED lamp requires the heat of the chip to be dissipated quickly, otherwise the LED light source will accumulate heat, making the light source Luminous decay occurs, which shortens the life of LED lamps. Using a heat sink with this structure, the heat is not easy to dissipate, and the heat dissipation area is small. If the heat dissipation area is increased, the volume of the lamp will increase, and the price of the lamp will increase.
