Description

The cooling LED light fixture
Technical field
The utility model relates to a kind of led lamp, is a kind of led lamp that has radiator structure specifically.
Background technology
Light emitting diode is as a kind of illuminating source since its have the luminosity height, produce when energy consumption is low, luminous that heat is low, advantage such as long service life, rich color and volume are little, by being applied in illumination and the decorative lamp more and more widely.Because single light emitting diode illumination is lower, people adopt with light emitting diode in parallel and or be together in series, the form that forms array provides to be enough to for people's illumination and environmental decoration light fixture.For powerful led lamp, owing in array, used the great light emitting diode of quantity, even the heat that produces during each lumination of light emitting diode is low, a large amount of use light emitting diodes, the middle heat that produces also is appreciable in the light fixture cavity of sealing relatively.And the increase of heat has reduced luminous flux, has reduced the high advantage of light-emitting diode luminance, and has influenced the service life of lumination of light emitting diode body.If the operating temperature of light emitting diode, then can add the possibility that the illuminator of big light-emitting diodes burns above 80 ℃.This shows that can the heat dissipation problem of led lamp be to be related to light emitting diode become the big problem of capturing illumination and/or ornamental lamp light source as main stream light sources.Up till now, people still do not find simple, the method for effective bulk storage diode artistic lamp heat.
Summary of the invention
The purpose of this utility model is to provide a kind of cooling LED light fixture, it is simple, the heat that can effective realization bulk storage led lamp when work, produces, improve the illumination of led lamp when work, prolong the service life of led lamp, reduce the cost of illumination or light decoration.
For realizing above-mentioned utility model purpose, the utility model adopts following technical proposals:
The cooling LED light fixture, comprise wiring board and light emitting diode, the plug-in unit face of wiring board is provided with the light emitting diode insert hole, on the another side of wiring board printed circuit is arranged, printed circuit and insert hole link, and the pin of light emitting diode inserts insert hole, is welded on the printed circuit, wiring board is passed in setting near circuit board package hole, and the pod apertures of not touching the printed circuit on the printed circuit board (PCB).
In technique scheme, said pod apertures can be the circular hole of diameter 3-20mm.
In technique scheme, said pod apertures can be independently, also can be cross one another.
In technique scheme, said pod apertures can be circle, ellipse, polygon or polygonal star pod apertures.
In technique scheme, said wiring board can be an epoxy resin board, and the phenolic resins plate also can be an aluminium base.
In technique scheme, the thickness of said wiring board is 0.3-3mm.
The quantity of said pod apertures can be determined according to the quantity of the light emitting diode that is provided with on the wiring board in the technique scheme, also can be more than light emitting diode, and arrange the position of the contiguous light emitting diode of the positional alignment of pod apertures.
The utility model has more following effects and good effect:
Because some wiring boards that pass are set near circuit board package hole, and do not touch the pod apertures of the printed circuit on the printed circuit board (PCB), when light emitting diode is switched on power supply, begin when luminous, the heat that light emitting diode produced, near the pod apertures of setting that will be by the wiring board insert hole, bulk storage is to the solder side one side of wiring board, plug-in unit face one side and solder side one side at the lamp interior wiring board form the thermal convection current exchange, make said plug surface and solder side heat balance, and then the shell by led lamp distributes around light fixture again.
In order to check effect of the present utility model, Augusts 2 in 2008, the Japanese patent application people carried out contrast test in the laboratory of oneself to the utility model and prior art product, and the result is as follows:
It is identical to get two appearance and sizes, the epoxy resin board wiring board, printed circuit is identical thereon, light emitting diode is 240 and arrange identical, one upward is provided with the pod apertures that 240 diameters reach 5mm according to technique scheme therein, under the condition of 28 ℃ of indoor temperatures, said two wiring boards are put into two lamp housings respectively, fixed temperature flowmeter sensor on the same position in two lamp housings, adopt same power initiation, switch on after two hours, 72 ℃ of the lamp housing Nei Wenduda of pod apertures are not set, the interior temperature of lamp housing that pod apertures is set is 66 ℃, has reduced by 6 ℃ than temperature in the lamp housing that pod apertures is not set.
The utility model provides a kind of cooling LED light fixture, it is simple, can effective realization bulk storage led lamp when work, produce heat, improve the illumination of led lamp when work, prolong the service life of led lamp, reduce the cost of illumination or light decoration.
