And fan cooling is adopted separately to circuit controller, can cause again the increase of overall power, cost, too increase the volume of circuit controller simultaneously, the reliability newly increasing radiator fan circuit also can affect the reliability of circuit controller entirety.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of LED automobile headlamp, and not only volume is little for it, structure is simple, and installs easily, and heat radiation is good, both reduce volume and the cost of cooling system, turn improve the global reliability of LED car lamp system simultaneously.
For solving the problem, the technical scheme that the utility model adopts is as follows:
A kind of LED automobile headlamp, the circuit controller comprising LED lamp, heat radiation lamp bracket and be located in heat radiation lamp bracket; Described LED lamp is fixed on heat radiation lamp bracket; Also radiator fan is provided with in described heat radiation lamp bracket.
Preferably, described circuit controller is positioned among the air channel of described radiator fan.
More preferably, described radiator fan is between circuit controller and heat radiation lamp bracket.
Preferably, described heat radiation lamp bracket is also provided with the first air vent.
More preferably, the quantity of described first air vent is multiple, and described first air vent line centered by the axis of described radiator fan, coaxial annular arranged is on heat radiation lamp bracket.
Preferably, LED automobile headlamp of the present utility model also includes bottom, and described bottom can be dismantled with heat radiation lamp bracket and connect into a shell structure, and described circuit controller and radiator fan are positioned at described shell structure.
More preferably, described bottom is provided with the 3rd air vent.
Preferably, described radiator fan is centrifugal fan or tube-axial fan.
Preferably, described circuit controller there is the second air vent.
Preferably, the axis of described radiator fan and the dead in line of described heat radiation lamp bracket.
Compared to existing technology, the beneficial effects of the utility model are:
LED automobile headlamp of the present utility model by having set up radiator fan in its heat radiation lamp bracket, utilize radiator fan to carry out active heat removal to heat radiation lamp bracket and circuit controller simultaneously, relative to the traditional LED automobile headlamp not arranging radiator fan, without the need to expanding the volume of heat radiation lamp bracket, good radiating effect can be obtained, and only need a set of cooling system can realize dispelling the heat to LED lamp and circuit controller simultaneously, reduce the cost of cooling system, improve heat radiation reliability, simultaneously because radiator fan is only arranged on traditional heat-dissipating lamp bracket inside, so the overall volume of LED automobile headlamp also can't be increased, LED automobile headlamp is convenient to be arranged in automobile lamp storehouse.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
