Together, the lower end of sheet metal is fixed on plastic cement lamp holder, and the upper end of sheet metal is weldingly fixed on metal reflector, LED light bar
It is fixed on metal reflector, reflection shield inner shield ring is formed on the inwall of metal reflector, the bottom of Transparent lamp shade forms
The outer back-up ring of Transparent lamp shade, the outer surface of the outer back-up ring of Transparent lamp shade is arc, and the outer surface of reflection shield inner shield ring is arc, clear lamp
The outer back-up ring of cover is fastened on the bottom of reflection shield inner shield ring, and Transparent lamp shade is outer to be clamped with sealing between back-up ring and reflection shield inner shield ring
Glue；
Wiring board is fixed on plastic cement lamp holder, and the LED lamp bead in LED light bar is electrically connected with wiring board by wire, circuit
Plate is electrically connected with screwed socket by wire.
Locating slot is formed on the plastic cement lamp holder, the lower end of sheet metal is L-type, and the lower end sleeve of sheet metal is in locating slot
In, the lower end of sheet metal is in extruding is fixed on locating slot after plastic cement lamp holder top heats.
The beneficial effects of the utility model are：
1st, it is radiated by sheet metal, and sheet metal exposes in atmosphere, its perfect heat-dissipating, while increased LED
The service life of lamp.
2nd, its sheet metal and plastic cement lamp holder are fixed together by hot melt, are so assembled very convenient.
Brief description of the drawings：

Specific embodiment：
Embodiment：As shown in Fig. 1 to 3, the LED with metal heat sink, including screwed socket 1 and plastic cement lamp holder 2, spiral shell
Line lamp holder 1 and plastic cement lamp holder 2 are fixed together, and the lower end of sheet metal 3 is fixed on plastic cement lamp holder 2, the upper end welding of sheet metal 3
It is fixed on metal reflector 4, LED light bar 5 is fixed on metal reflector 4, is formed on the inwall of metal reflector 4 reflective
Cover inner shield ring 41, the bottom of Transparent lamp shade 6 forms the outer back-up ring 61 of Transparent lamp shade, and the outer surface of the outer back-up ring 61 of Transparent lamp shade is arc
Shape, the outer surface of reflection shield inner shield ring 41 is arc, and the outer back-up ring 61 of Transparent lamp shade is fastened on the bottom of reflection shield inner shield ring 41, thoroughly
Bright lamp cover is outer to be clamped with fluid sealant between back-up ring 61 and reflection shield inner shield ring 41；
Wiring board 7 is fixed on plastic cement lamp holder 2, and the LED lamp bead in LED light bar 5 is electrically connected with wiring board 7 by wire,
Wiring board 7 is electrically connected with screwed socket 1 by wire.
Locating slot 21 is formed on the plastic cement lamp holder 2, the lower end of sheet metal 3 is L-type, and the lower end sleeve of sheet metal 3 exists
In locating slot 21, the lower end of sheet metal 3 is in extruding is fixed on locating slot 21 after the top of plastic cement lamp holder 2 heats.
Operation principle：The outer back-up ring 61 of Transparent lamp shade is fastened on the bottom of reflection shield inner shield ring 41, the outer back-up ring 61 of Transparent lamp shade
Fluid sealant is clamped with and reflection shield inner shield ring 41 between；It is very convenient when so installing, will first be applied on the outer back-up ring 61 of Transparent lamp shade
Upper fluid sealant, during Transparent lamp shade 6 then inserted into reflection shield 4 as shown in Figure 1 again, just completes Transparent lamp shade and reflection shield
Installation.
The lower end of sheet metal 3 is L-type, first by the lower end of sheet metal 3 insertion locating slot 21, then the moment of sheet metal 3 is added
Heat, and the frid on the side of locating slot 21 2 is extruded, such sheet metal 3 has just been fixed on plastic cement lamp holder 2.
Metal reflector of the present utility model 4 and sheet metal 3 form metal heat sink, and it is anti-using the metal of metal material
Light shield 4 and sheet metal 3 radiate come the heat energy to the LED lamp bead generation in LED light bar 5, good heat dissipation effect.
