In order to achieve the above object, the technical scheme that the utility model adopted is as follows:
The high well lamp of a kind of great power LED comprises lamp socket power supply cover, power supply driver, radiator, LED lamp, PCB circuit board and diffuser, and the high well lamp of described great power LED also comprises dust cover, described dust cover and radiator socket.
As preferably, described radiator comprises a plurality of radiating fins, a plurality of radiating fins with radial around combination; Described dust cover comprises a plurality of dustproof sheets, a plurality of dustproof sheets with radial around combination; Described dustproof sheet is between radiating fin.Described radiator and dust cover are fixed on the annulus fixed frame, and described annulus fixed frame is metal ring fixed frame or plastic circle ring fixed frame.The diameter of described radiator is greater than the diameter of dust cover.Described radiating fin is provided with a plurality of air-vents.
As preferably, the high well lamp of described great power LED also comprises the aluminium cooling base, and described aluminium cooling base is socketed in the radiator.The high well lamp of described great power LED also comprises aluminium sheet, and described aluminium sheet is installed on the aluminium cooling base, and described PCB circuit board is installed on the aluminium sheet.
As preferably, described power supply driver is installed in the lamp socket power supply cover by angle Support.
As preferably, described lamp socket power supply cover is provided with ventilating groove, and described lamp socket power supply cover is metal lamp holder power supply cover or nonmetal lamp socket power supply cover.
As preferably, described dust cover is the metal dust cover.Described radiator is a metal heat sink.Described diffuser is the PMMA diffuser, and described diffuser not only reaches the effect of optically focused, also has the dustproof function.
The utility model compared with prior art, increased the dust cover that is made of a plurality of dustproof sheets, dust cover and radiator cooperatively interact, and form inside and outside double-decker, prevent that effectively dust from entering, guaranteed the job stability of the high well lamp of LED and prolonged its service life; By the radiator that a plurality of radiating fins constitute, its radiating fin is provided with a plurality of air-vents, can strengthen radiating effect greatly; The utility model also has energy-conserving and environment-protective, the advantage of good looking appearance.
Description of drawings
Fig. 1 is the structural representation of the high well lamp of the great power LED of the utility model embodiment;
Fig. 2 is the fractionation structural representation of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the high well lamp of a kind of great power LED comprises lamp socket power supply cover 1, power supply driver 9, radiator 2, LED lamp, annulus fixed frame 8, PCB circuit board 6, aluminium sheet 5, aluminium cooling base 4, diffuser 7 and dust cover 3.Described LED lamp is mounted on the PCB circuit board 6.Described aluminium cooling base 4 is socketed in the radiator 2, and described aluminium sheet 5 is installed on the aluminium cooling base 4, and described PCB circuit board 6 is installed on the aluminium sheet 5.Described diffuser 7 is installed in the place ahead of PCB circuit board 6, and diffuser 7 is made by the PMMA material, and the effect of optically focused is not only arranged, and also has the dustproof function, prevents that dust from entering LED lamp and PCB circuit board 6.
Described dust cover 3 and radiator 2 sockets.Be specially, described radiator 2 comprises a plurality of radiating fins 21, a plurality of radiating fins 21 with radial around combination, can be around being combined on the aluminium cooling base 4; Described dust cover 3 comprises a plurality of dustproof sheets 31, a plurality of dustproof sheets 31 with radial around combination, also can be around being combined on the aluminium cooling base 4; Described dustproof sheet 31 is between radiating fin 21, and promptly radiating fin 21 and dustproof sheet 31 are to place as the bamboo between plum blossom, can have certain clearance between two radiating fins 21, and in order to strengthen dustproof effect, it is close with the gap that the width of dustproof sheet 31 can be made.The diameter of described radiator 2 is greater than the diameter of dust cover 3, and promptly dust cover 3 is the equal of to be nested in the radiator 2.In order to strengthen radiating effect, radiating fin 21 is provided with a plurality of air-vents 22; Described radiator 2 and dust cover 3 are made by metal material; Described radiator 2 and dust cover 3 together are fixed on the annulus fixed frame 8, and described annulus fixed frame 8 can be made by metal or plastic material.
Described power supply driver 9 is installed in the lamp socket power supply cover 1 by angle Support 10, and promptly lamp socket power supply cover 1 promptly is that lamp socket is again the housing that power supply driver 9 is installed.Described lamp socket power supply cover 1 is installed on the radiator 2.In order to improve radiating effect, it also can be enclosed that described lamp socket power supply cover 1 is provided with ventilating groove 11(lamp socket power supply cover 1), lamp socket power supply cover 1 is made by metal or nonmetallic materials.Power supply driver 9 provides operating voltage for the LED lamp.
The power panel held against heat sink 2 of the power supply driver 9 of present embodiment, aluminium cooling base 4 held against heat sink 2, LED lamp and PCB circuit board 6 transmit heat by aluminium sheet 5 and aluminium cooling base 4 to radiator 2, thereby the heat of LED lamp release and the heat of power panel are distributed, guarantee the normal operation of LED lamp and power circuit.Unique dustproof sheet stops entering in the light fixture of dust.
The foregoing description is that the utility model is comparatively preferably a kind of, and simple change that those skilled in the art make in protection domain of the present utility model or replacement all drop in the protection domain of the present utility model.
