The utility model content
The technical problem that the utility model will solve is: to the heat radiation defective that above-mentioned prior art exists, a kind of radiator structure of the LED of reduction temperature is provided.
The utility model is to address the above problem the technical scheme that proposes to be: a kind of led light source assembly, comprise the aluminium base that has LED, and the back side of aluminium base is provided with radiator, scribbles heat-conducting cream between aluminium base and the radiator; LED is welded on the front of aluminium base.
In a preferred embodiment, the led light source assembly also comprises the reflector that the aluminium base top is provided with, and the aluminium base that has LED is fixed on the screw column of reflector through screw.
In a preferred embodiment, this led light source assembly also comprises transparent member, and transparent member is arranged on the front portion of reflector.
In a preferred embodiment, the structure of radiator is provided with the many thermal columns vertical with the heat transfer bottom surface for the heat transfer bottom surface parallel with aluminium base.
In a preferred embodiment, the heat transfer bottom surface is provided with screw mounting hole.
In a preferred embodiment, screw passes the screw mounting hole on heat transfer bottom surface and the aluminium base successively, and radiator and the aluminium base that has LED are fixed on the screw column of reflector together.
Compared with prior art, adopt the advantage of the technical scheme of the utility model to be: through the contact area of radiator increase aluminium base and air, to strengthen cross-ventilation and heat conduction, reduced the LED junction temperature, the prolongation LED life-span.
