Abstract
The utility model discloses an LED down lamp utilizing water-cooled radiating, which comprises a support and a lamp cup, wherein LED lamps are full mounted on the inner surface of the lamp cup, a heat absorbing channel is arranged on the peripheral surface of the lamp cup, a radiating channel is arranged on the support, a loop passage is formed by connecting the two channels end to end and filled with water, a miniature motor is arranged in the loop passage, and the radiating channel is provided with radiating fins. Compared with the conventional air-cooled lamp, the LED down lamp utilizing water-cooled radiating has high radiating efficiency and fine radiating effect, and can realize fast radiating, reduce working environment temperature, prolong service life of LED lamps and stabilize lighting effect.
Description
Technical field:
The utility model relates to a kind of LED Down lamp of water-cooling.
Background technology:
Since the LED lamp emerges, because it has the light efficiency height, volume is very little, colour rendering is high and the life-span is long, so more and more occasions all adopt LED to replace traditional light source to throw light on, but it also has significant disadvantages, requirement to temperature is also high, if the too high stability that will have a strong impact on its light efficiency of its operating temperature reduces service life greatly.In order to address the above problem, radiating mode commonly used at present is to utilize the electric fan blowing, and near the heat the LED lamp is taken away, but air-cooled mode radiating effect is relatively poor, the process of blowing usually is subjected to stopping of other object, and it is freely suitable to influence flowing of wind, reduces radiating efficiency.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, the water-cooling LED Down lamp of a kind of radiating efficiency height, good heat dissipation effect to be provided.
For achieving the above object, the technical scheme that the utility model provides is: a kind of LED Down lamp of water-cooling, include support and Lamp cup, on the inner surface of Lamp cup, stick the LED lamp, on the Lamp cup outer peripheral face, be provided with the heat absorption runner, be provided with the heat radiation runner on support, two runners formation loopback from beginning to end passage is full of water in the loopback runner.
In the loopback passage, be provided with micro motor.
On the heat radiation runner, be provided with fin.
Compare traditional air-cooledly, this water-cooled LED Down lamp has radiating efficiency height, good heat dissipation effect, can realize the purpose of quick heat radiating, reduces operating ambient temperature, improves the service life of LED lamp and stablizes its light efficiency.
Description of drawings:
Fig. 1 is the structure chart of the utility model LED Down lamp.
The specific embodiment:
Now describe the utility model structure in conjunction with the accompanying drawings in detail.
The LED Down lamp of present embodiment water-cooling includes support 1 and Lamp cup 2, on the inner surface of Lamp cup 2, stick LED lamp 3, on Lamp cup 2 outer peripheral faces, be provided with heat absorption runner 4, on support 1, be provided with heat radiation runner 5, the inlet of heat absorption runner 4 is located at the bottom of Lamp cup 2, the top is located in outlet, and heat radiation runner 5 and heat absorption runner 4 formation loopback passages from beginning to end are full of water in the loopback runner.Utilize thermal convection principle, make circulating that water in the loopback runner stops.
In order to accelerate the speed of current, improve the efficient of heat radiation, in the loopback passage, be provided with micro motor 6.
On heat radiation runner 5, be provided with many row's fin 7, thereby increase area of dissipation.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
