Embodiment Construction

[0014] Below in conjunction with accompanying drawing and example description embodiment of the present invention, as shown in Figure 1, lamp body 9 is divided into rear part and front part, and rear part outer surface is made with fin-shaped cooling structure, also can be made into columnar cooling structure (in the figure not shown). The rear part of the lamp body 9 and the fin-shaped heat sink are made of cast aluminum, and the inner surface of the rear part of the lamp body 9 is smooth, which can be closely connected with the LED heat sink, and thermally conductive glue is coated therebetween to facilitate heat conduction of the heat sink. The front portion of the lamp body 9 adopts tempered glass as the light-transmitting window 10 .

[0015] A street lamp body 9 can be composed of a plurality of LED heat sinks 5 and LED light sources 4, and the LED light sources 4 on the LED heat sinks 5 are connected by a metal PCB board 6, and the metal PCB board 6 has holes correspond...

Abstract

The present invention relates to the application of high power LED in semiconductor lighting, and is especially high power LED street lamp. The high power LED street lamp of the present invention includes lamp body at least one LED light source and its heat sink, and metal PCB board for the circuit connection of LED light source. The metal PCB board fixed on the lamp body has at least one hole for the heat sink to be installed in, the heat sink has one metal column as the main body, disc bottom fixed on the inside surface of the lamp body and top for connecting the LED light source. The high power LED street lamp of the present invention has good heat dissipating effect, reliable operation, simple light path design and easy assembling.

Description

technical field [0001] The invention relates to the application of high-power LEDs in semiconductor lighting, in particular to high-power LED street lamps, and belongs to the field of semiconductor lighting. Background technique [0002] The main light sources of traditional street lamps are metal halide lamps and fluorescent lamps. These light sources are large in size, simple in electrical circuits, and resistant to high temperatures, so traditional lamps are large in size and poor in heat dissipation. In recent years, with the development of semiconductor technology and the successful development of GaN high-power LEDs, LEDs have been widely used as semiconductor light sources in signal display, backlighting, and landscape lighting. With the continuous improvement of high-power white LED light efficiency and the development of high-power LED packaging technology, semiconductor light sources have gradually been applied to the field of white light lighting. Semiconductor l...
