Abstract
The utility model discloses a radiating-improved parabolic aluminum reflector (PAR) lamp, which comprises a shell, a flexible printed circuit board (PCB), a lithium magnesium alloy radiating fin and an aluminum radiator. A plurality of light-emitting diode (LED) lamps are arranged in front of the flexible PCB which is arranged in a cavity with a shell, and the back of the flexible PCB is fixed on the lithium magnesium alloy radiating fin which is fixed on the aluminum radiator. By adding the lithium magnesium alloy radiating fin which is high in heat conducting coefficient and quick in heat conducting, the radiating-improved PAR lamp rapidly conducts heat generated in working of the flexible PCB to the aluminum radiator, and the heat accumulated in the flexible PCB is very little so that the flexible PCB is relatively low in temperature. The radiating-improved PAR lamp is simple in structure, low in cost and fast and good in radiating, improves light-emitting efficiency of the LED lamps of the flexible PCB and prolongs service life of the PAR lamp of the flexible PCB.
