Described LED lamp plate places within the PC protective cover; the led light source regular arrangement is on lamp plate; the LED lamp plate is copper base; heat transfer efficiency is far longer than normally used aluminium base; the heat that has guaranteed LED is derived smoothly; the LED lamp plate is fixed on the aluminum profile heat radiator with high thermal conductivity, makes LED have good heat dissipation environment, has guaranteed the service life of LED.

Described radiator is the aluminium section bar of high thermal conductivity, and the fin direction of radiator is vertical direction, for being conducive to most cross-ventilated direction, has improved the radiating efficiency of radiator, has realized the heat radiation of great power LED.

What described power pack adopted is built-in driving power, realizes stabling current output by the driving power conversion.

Adopt light emitting diode (LED) as light source, do not damage photographed object, LED is cold light source, and the life-span is longer, failure rate is low; Low-power consumption, conservation of power, the later stage uses, maintenance cost is lower

Shell mechanism spare uses a kind of aluminium section bar of high thermal conductivity, firm heat conduction and protective effect, and led light source places the protection within the shell, and realizes high light efficiency output.

The utility model has used the PC protective cover of high transmission rate, and reflection shield makes reflecting effect and the light utilization maximization of reflection shield through optical analog emulation, has realized light distribution requirements and the output of high light efficiency of light fixture.
