Description
Technical field:
The present invention relates to a kind of lighting device.
Background technology:
Existing lamp is except the LED lamp, the power consumption of other lamp is all very big with respect to the LED lamp, though that the LED lamp consumes energy is little, the brightness of general LED lamp is not enough, enough its heating of LED lamp of brightness is higher relatively, if heat radiation is untimely, can have a strong impact on its service life, and, in order to promote brightness, often need several LED lamps to use simultaneously, at present, the lamp that is made of several high-brightness LED lamps often makes the service life of these lamps not long because heat radiation is bad.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of have high brightness, low power consuming, long-life lamp.
The present invention realizes like this, mainly constitute by the wiring board that is provided with several LED lamps, the energy storage plate, heat pipe, fin, the lamp housing that are arranged on below the wiring board, wiring board, energy storage plate, heat pipe, fin are arranged on the lamp housing, wiring board abuts against on the energy storage plate, and heat pipe and energy storage plate, fin couple together.During work, the LED lamp with the thermal energy transfer sent to wiring board, wiring board again with thermal energy transfer to energy storage plate, energy storage plate by heat pipe with thermal energy transfer to fin, by fin thermal energy transfer is gone out again.Distribute because the heat energy of LED lamp is the transmission by heat pipe, like this, the heat energy that the LED lamp is sent is promptly passed by heat pipe, makes the LED lamp can its temperature be raise rapidly and influences its service life.Because the heat energy that the LED lamp is sent is promptly passed by heat pipe, the LED lamp of a lot of high brightness just can be set thick and fast, so that promote the brightness of lamp significantly on the wiring board.
Here, for the heat energy that makes the LED lamp can be delivered to rapidly on the wiring board, wiring board by the bottom heat sink, be positioned at the insulating barrier on the bottom heat sink, the conductive layer that is positioned at above the insulating barrier constitutes, the perforation that the radiating end of LED lamp passes conductive layer, insulating barrier abuts against on the bottom heat sink, and the power connector end of LED lamp is connected with conductive layer.The bottom heat sink is an aluminium alloy plate, and conductive layer is copper conductive layer.Because adopt the high aluminium alloy plate of heat transfer efficiency, like this, the heat energy that the LED lamp is sent promptly is delivered on the bottom aluminium alloy heat sink by its radiating end, passes by energy storage plate, heat pipe then.
In order to prevent that the heat energy that fin distributes from can cause the LED light temperature to raise, and is provided with insulated wall between LED lamp that has energy storage plate and fin.
Fin is positioned at lamp housing, and the side of lamp housing is provided with louvre, so that heat energy is dispersed into outside the lamp housing by cross-ventilated mode.
In order to promote radiating efficiency, heat pipe and lamp housing couple together.Like this, by having the larger area lamp housing, just can promote the speed of distributing of heat energy.
Here, energy storage plate is that arc surface connects or sphere connects with being connected of bottom heat sink of wiring board.Because the operation principle of heat pipe is that the past heat pipe of the heat energy of heat pipe lower end upper end is transmitted, therefore, during use, the requirement heat pipe is vertical, and the service orientation of lamp is uncertain often, adopt energy storage plate to be connected with the bottom heat sink arc surface of wiring board or the sphere connection, the different light angles that reach lamp are used, and all easily heat pipe are turned on the upright position.
Compared with the prior art the present invention has high brightness, low power consuming, long-life advantage.
