High-power LED illumination lamp metal radiator and manufacturing method

Abstract

The invention relates to a high-power light emitting diode (LED) illumination lamp metal radiator and a manufacturing method. The radiator comprises a radiating shaft and radiating fins, wherein the radiating shaft is of a cylinder, the circle center of the cylinder is provided with a through hole, two end faces of the radiating shaft are correspondingly provided with positioning holes communicated at two ends, the circumferential surface of the radiating shaft is uniformly provided with a plurality of U-shaped insert slots and V-shaped pressing plate slots in the same number as the U-shaped insert slots, and the U-shaped insert slots and the V-shaped pressing plate slots are formed at intervals; the radiating fins are rectangular sheets, two angles at the upper ends of the radiating fins are symmetrical arc angles, and the surfaces of the radiating fins are provided with a plurality of rectangular reinforcing slots and a plurality of radiating holes; and the right-angled sides of a plurality of radiating fins are extruded into the plurality of U-shaped insert slots on the radiating shaft respectively. The radiator has the advantages that the radiating efficiency is improved, the weight and the volume are reduced and the consumption of raw materials is reduced. The radiator can directly replace the conventional incandescent lamp or energy-saving lamp, so the application range of the radiator is enlarged, the application of an LED illumination lamp is more convenient and the application range is wider.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a metal radiator of a high-power LED lighting lamp and a manufacturing method thereof. Background technique [0002] At present, the development speed of LED lighting in my country is very fast, and the integration of luminous body chips is getting higher and higher, and the single chip has reached the level of high power. However, the problem of heat dissipation of LED light sources is still prominent. The heat dissipation of medium and high-power LED lighting lamps mostly adopts integral cast aluminum heat sinks, which are large in size and heavy in weight. Some LED lighting lamps design the radiator and lamps into one, for example: LED industrial and mining lamps design the radiator and lampshade as one, the radiator of LED street lamps is the lampshade, etc., the original lighting should be replaced with LED lighting It is necessary to replace the lamps as a whole, and some even chan...

However, the problem of heat dissipation of LED light sources is still prominent. The heat dissipation of medium and high-power LED lighting lamps mostly adopts integral cast aluminum heat sinks, which are large in size and heavy in weight.

Some LED lighting lamps design the radiator and lamps into one, for example: LED industrial and mining lamps design the radiator and lampshade as one, the radiator of LED street lamps is the lampshade, etc., the original lighting should be replaced with LED lighting It is necessary to replace the lamps as a whole, and some even have to change the original decoration, causing unnecessary waste and trouble
