Technical field
The utility model relates to lighting apparatus, relates in particular to a kind of high-power LED lamp.
Background technology
Advantages such as the LED light fixture has the light efficiency height, and power consumption is little, and the life-span is long apply to every field widely.The LED lamp can produce a large amount of heats when intensive the setting, for solving heat dissipation problem, at present the LED lamp is installed on the heat sink of big plane, so causes LED light fixture volume big, and radiating effect is also unsatisfactory; The LED lamp uses dc source, generally will carry out using for the LED lamp after the transformation rectification to AC power with transformer again, has so increased the cost of LED light fixture.
Summary of the invention
The utility model is the above-mentioned deficiency that will solve prior art, designs a kind of small volume structure compactness, not with the LED light fixture of transformer.
For solveing the technical problem, the technical scheme that the utility model proposes is: a kind of high-power LED lamp, it comprises: the printed circuit board (PCB) of tubulose, be distributed in the LED lamp in the printed circuit board (PCB) outside, be arranged on the interior side radiator of printed circuit board (PCB) inboard, be arranged on the radiator fan on the printed circuit board (PCB) axle center, the control circuit of control LED lamp and radiator fan.
In a preferred embodiment, the outside at tubulose printed circuit board (PCB) two ends is provided with outer side radiator.Radiator fan is arranged on described printed circuit board (PCB) one end, and the other end of printed circuit board (PCB) is provided with ventilating opening.Control circuit is arranged on the inboard away from printed circuit board (PCB) one end of radiator fan.Control circuit is included in the bridge rectifier that power input seals in choking-winding, and radiator fan and LED lamp polyphone are connected on the bridge rectifier direct current power supply loop.Control circuit comprises and being serially connected on the power input, and is installed in the temperature detect switch (TDS) in the inboard heat radiation.
The disclosed high-power LED lamp of the utility model adopts column construction, and the center of cylindricality is provided with fin and radiator fan; On circuit, the cancellation transformer is powered to LED lamp that is cascaded and radiator fan with constant-current source.This high-power LED lamp has small volume structure compactness, low cost and other advantages.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
