Abstract

The utility model relates to a lighting appliance, in particular to a high-power light-emitting diode (LED) lamp which comprises an LED (1) installed on a printed circuit board (PCB) (2). The PCB (2) is fixed on a radiator which comprises a heat-dissipation board (3) and a heat-dissipation cup (5). The end of the heat-dissipation cup (5) is adhered to the surface of one side of the heat-dissipation board (3) through heat-conducting silica gels (4), and the surface of the other side of the heat-dissipation board (3) is fixed on the PCB (2). The high-power LED lamp adopts the radiator which is formed by combining the heat-dissipation board and the heat-dissipation cup, can dissipate heat generated by the LED in time, and prolongs the service life of the lamp. The heat-dissipation board is adhered to the heat-dissipation cup through the heat-conducting silica gels, accordingly the full heat contact between the heat-dissipation board and the heat-dissipation cup is guaranteed, and the heat-dissipation stability is guaranteed.

Description

A kind of high-powered LED lamp
Technical field
The utility model relates to a kind of lighting apparatus, relates in particular to a kind of high-powered LED lamp.
Background technology
LED has characteristics such as long service life, response time weak point, opto-electronic conversion usefulness height, energy-conserving and environment-protective, is widely used in fields such as various indications, demonstration, decoration, backlight, illumination.Those skilled in the art are well-known, when LED lights, because constantly assembling, heat cause temperature progressively to raise, as effectively not dispelling the heat, corresponding the successively decreasing of luminous light intensity meeting of LED under the light decay effect, when especially a plurality of LED were combined into the LED lamp, heat accumulation was faster and then produce high temperature, caused the shortening in service life of LED lamp.
Common LED etc. adopts board-like fin to dispel the heat, but for high-power LED, its heat sinking function seems narrower, has become a technical barrier so how to solve the heat radiation of great power LED etc.
The utility model content
The utility model provides a kind of high-powered LED lamp, and it is having high-power and high-luminance, and heat radiation is good, long service life.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:
A kind of high-powered LED lamp comprises the LED that is installed on the pcb board, and described pcb board is fixed on the radiator; Described radiator comprises heat sink and heat radiation cup, and the termination of described heat radiation cup sticks on a side surface of heat sink with heat conductive silica gel; The opposite side surface of heat sink is pcb board fixedly.
Described pcb board and heat sink all are discoid, and with the concentric setting of heat radiation cup;
Described LED has 5, and is evenly distributed around the center of pcb board;
The appearance of described heat radiation cup has 36 chip fin of dispersing arrangement.
The beneficial effects of the utility model are: adopt the radiator of heat sink and the combination of heat radiation cup, can in time distribute the heat that LED produces, prolonged the service life of waiting; Adopt heat conductive silica gel to paste between heat sink and the heat radiation cup, guarantee the abundant thermo-contact of heat sink and heat radiation cup, guarantee that heat radiation is stable; Special heat radiation cup structure further strengthens heat radiation function.
Description of drawings
Fig. 1 is the structural representation of a kind of high-powered LED lamp of the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred implementation of a kind of high-powered LED lamp of the utility model is made detailed description:
As shown in figures 1 and 3, pcb board 2 is discoid, and 5 LED1 are installed on it, and LED1 adopts the large-power LED light bead of 1w, and 5 LED1 are evenly distributed around the center of pcb board 2.Pcb board 2 is fixedly mounted on a side surface of heat sink 3, and heat sink 3 is the disk of aluminium matter, and pcb board 2 contacts with heat sink 3 close thermal.
As depicted in figs. 1 and 2, fixedly connected with the termination of heat radiation cup 5 in the opposite side of heat sink 3 surface, with heat conductive silica gel 4 both is pasted together earlier, with screw the two fixed again, dispels the heat glasss 5 and heat sink 3 concentric settings.Heat radiation cup 5 also is the fin of aluminium matter, extends 36 chip fin of dispersing arrangement on its outer surface, and so the fin of shape can adopt the method for one stretching to make.
As depicted in figs. 1 and 2, the center of heat sink 3 has circular hole, passes with supply lines.Be connected to transformer 6 on the electric wire in advance, then electric wire passed the center of heat radiation cup 5, pass the center hole of heat sink 3 again, connect, both made this high-power LED lamp with pcb board.
