As the preferred structure of one, louvered fins can be provided with between described fork shape fin and another fork shape fin, the height of this fork shape fin higher than the height of louvered fins, and can be provided with radiator fixing hole in the fork intersection of part fork shape fin.
Be connected at described fork shape fin and circular radiating band and form air inlet, louvered fins also can be connected with circular radiating band or not be connected, and LED electrical string holes can be opened in louvered fins side.
In the plane of described fluted body reflector, be fixed with LED aluminum base plate, and be electrically connected with metallic lamp holder and LED drive board by LED electrical string holes.
Angle reflector is surrounded with in addition on the side of described fluted body reflector, or do not arrange, and surround LED aluminum base plate and fluted body reflector with Transparent lamp shade, inner seal ring and exterior seal ring, outside Transparent lamp shade with bolt and lampshade fixed leg fastening, hollow plug and stopper fixing hole also use bolted.
LED lamp specification kind of light fixture when practical application is a lot, the size of the change of the maximum gauge of hollow radiator or fork shape fin and louvered fins can suitably be changed, so that the light fixture of different capacity can select suitable shape specification, improve its radiating effect.
The beneficial effects of the utility model are, due on the fluted body reflector of hollow radiator and around be provided with fork shape fin and louvered fins, and center is provided with the hollow plug of air inlet in its lower section.So radiator structure is simply compact, fork shape fin improves heat loss through radiation effect, and is easily assembled into various high power LED lamp.
Hollow plug is provided with air inlet, and add the cross-ventilation heat radiation of hollow radiator, and eliminate " tropical island effect " at the radiator center of high power LED lamp, therefore, it is little that this device has volume, the feature that radiating efficiency is high.
Hollow plug can arranging various sensor, such as sound, light sensor and infrared human body inductor, optic communication sensor or other sensors, creating locus for realizing intelligent light fixture.
In order to the heat of LED drive board dispels the heat rapidly, casting glue is injected on around insulation crust and LED drive board, and be made of one power supply by heat insulation cover plate for sealing, so that the heat of LED drive board distributes rapidly, so can reduce costs and weight, and the LED drive board life-span can be extended, improve its functional reliability.
The utility model is suitable for developing the courtyard lamp lightings such as the assembling ceiling light of indoor large space general illumination, factory lamp and hanging lamp, also can realize intelligent lighting light fixture.
