Problems solved by technology

[0002] Existing high-power LED lighting design has the problems of heat dissipation and light distribution; the current heat dissipation technology dissipates heat for a limited-area aluminum substrate, and packages the high-power LED chip on a small (about 5mm) copper substrate to make a 1-watt or 3-watt lamp holders, and then fix several (tens to hundreds) 1-watt (3-watt) lamp holders on the aluminum plate with screws or heat-conducting glue for heat dissipation, because there is heat between the lamp holder and the aluminum substrate Resistance, the heat dissipation area of ​​the aluminum substrate is limited, causing the working heat of the Led to be unable to be exported, causing the temperature of the Led chip to rise sharply, and the temperature of the aluminum substrate (that is, the working environment temperature of the chip) greatly exceeds the allowable working temperature of the chip, so long-term work will lead to The light attenuation of LED lights increases, the brightness decreases, and the service life is greatly shortened

Embodiment 1

[0026] As shown in Figures 1 to 3, four high-power LED lamp holders 1 are evenly arranged on the radiator 2, and the heat sink 3 of the radiator 2 is provided with two axially penetrating air ducts, which are connected through metal sleeves. The radiator embedded with high-power LED lamp head is fixed on the street lamp bracket. One end of the metal sleeve is connected to the radiator by bolts, and the other end of the tube wall is provided with a screw hole, and there is a screw hole in the screw hole for fixing the metal sleeve. Bolts for street lamp brackets; this embodiment is suitable for high-power LED street lamps.

Embodiment 2

[0028] As shown in Figures 4-6, the two high-power LED lamp holders 1 are evenly arranged on the radiator 2, and the heat sink 3 of the radiator 2 is provided with two axially penetrating air ducts, which are inserted through the metal base. A radiator with a high-power LED lamp head is fixed in the tunnel, a bracket is provided on the metal base, and the bracket is movably connected to the radiator through bolts; this embodiment is suitable for high-power LED tunnel lights.

[0029] In the present invention, several high-power LED chips are directly integrated and bound on the aluminum substrate according to certain rules, and then the integrated lamp board is fixed on an aluminum alloy lamp holder (the heat conduction area greatly exceeds that of the aluminum substrate). Led lamp holder: Fix the super-high-power LED lamp holder on the aluminum alloy (6063#) radiator with a thickness of 10mm and an air duct type heat pipe on the back with heat-conducting glue, and completely e...
