Offer ventilating heat dissipating hole on the described lamp housing.Caloric value is bigger during LED work, and ventilating heat dissipating hole is convenient to heat radiation.Lamp housing is provided with filter screen in the ventilating heat dissipating hole inboard, and filter screen prevents that effectively extraneous dust impurity from entering in the lamp housing under the prerequisite that guarantees the ventilation and heat function.
The radiator of described lighting module links to each other with lamp housing by heat-conducting piece, as radiator, has increased area of dissipation with lamp housing, further improves radiating effect.
Described drive circuit module is located on the lamp stand.For the LED light fixture, the fault rate of circuit is far above the LED lamp holder, and prior art all is located at circuit in the lamp housing (lamp holder), maintenance, loading and unloading inconvenience.The utility model is located at drive circuit module on the outer lamp stand of lamp holder, safety easy to maintenance, and be convenient to the circuit heat radiation.
The beneficial effects of the utility model are: by being set, rotating lighting module reached the purpose of being convenient to regulate local illumination and range of exposures, and easy to use, reliable operation, perfect heat-dissipating.
