The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Among Fig. 1, existing LED light fixture consists of illuminator by LED luminescent device 1 usually, and the LED luminescent device is positioned at wiring board 2(aluminium base or printed circuit board (PCB)) on, wiring board is fixed in the lamp casing 3.
Adopt the light fixture of this structure, procapsid is PC(Polycarbonate transparent or atomizing (mixed light effect), Merlon, a kind of in the engineering plastics) material.
Fire resistance or the resistance to elevated temperatures of makrolon material are poor, are unfavorable for fire protection requirement, so that the scope of application of LED light fixture is restricted.
In addition, because the LED light fixture of this kind structure only depends on wiring board heat radiation (can be referred to as the thermal convection current radiating mode), its radiating effect is poor, affects the light fixture performance, only is only applicable to the small light tool.
Among Fig. 2, anter lamp casing is wherein made (being referred to as traditionally the PC lampshade) with makrolon material transparent or atomizing (playing the mixed light effect) usually, the rear panel lamp casing is generally aluminum material, wiring board directly is fitted on the back cover, and the heat that produces when relying on aluminium that line is worked the LED luminescent device conducts (can be referred to as the heat conducting and radiating mode).
Because the rear panel lamp casing of the LED light fixture of this structure is metal material (usually adopting aluminium), on circuit design, just can't adopt the self-rectifying circuit form, need power supply is external, otherwise defective, volume and the structural complexity of the LED light fixture that increases virtually.
The transmission of heat energy has three kinds of modes: hot conduction, thermal convection current and heat radiation.By Fig. 1 and Fig. 2 as can be known, mainly set about from heat conduction and two angles of thermal convection current for the research of LED heat dissipation technology at present, this has limited development and the range of application of high-power LED lamp to a certain extent.
Among Fig. 3, the technical program is provided with a plurality of LED luminescent devices 1 on a face of LED wiring board 2, on the another side of LED wiring board, be provided with heat loss through radiation coating 5; At the inwall of lamp casing 3, be provided with light-mixed layer 6; Lamp casing is glassy layer.
Wherein, described heat loss through radiation coating is carbon dust radiation paint layer.
Described light-mixed layer is halogen powder light-mixed layer.
The tubulose that described lamp casing is integrated or spherical whole glass lamp housing.
In the conventional fluorescent, the halogen powder inspires visible light as the fluorescent material Ultraviolet radiation absorbing, and its life-span only had about 1500 hours.
In the technical program, the halogen powder is not excited, but as the mixed light materials'use, the life-span just is not a problem.In addition, the transmitance of halogen powder is also higher, helps to improve the bright dipping quality of LED light fixture.
Simultaneously, adopt the clear glass material as lamp housing in the technical program, glass can effectively see through infra-red radiation, guarantees that radiation paint goes out heat radiation.
The advantage that replaces traditional aluminum lamp housing with glass is:
1, cost is low;
2, security improves: at present if back cover be metal material just can't self-rectifying, the need power supply is external, otherwise defective.In addition, PC material fire resistance also has problem;
3, good looking appearance: traditional combined lamp high-end market more difficult to get access.
Be subject to demand energy-conservation and that product is compact, non-active heat radiation is paid attention to day by day, the ultrared coating radiating mode of application of radiation is quite popular at present research field, particularly be applied to the products such as high-capacity LED and solar cell, its heat radiation quality can directly be reacted on product usefulness, and in order to adapt to the requirement of energy-saving and emission-reduction, this series products can not install fan cooling additional usually.
At present, radiation paint is multiplex in fields such as building (external wall) and industrial production (high-temperature boiler), and the application in the LED field of radiating rarely has finding.
Existing application case is that radiation carbon dust coating is coated on the shell of light fixture, but radiation paint (carbon dust) is applied and lamp outer casing, and use amount is larger, and cost of goods manufactured is higher, and each lamp outer casing is different, causes the difficult operation of actual spraying.
In the technical program, adopt the mode of electrostatic spraying directly to be attached to (aluminium base, pcb board etc.) on the wiring board radiation carbon powder material, its essence is the ability of the radiations heat energy of having strengthened wiring board itself; In addition, the radiation carbon powder material directly is coated on aluminium base, raw material uses few, and simple to operate, radiating effect is more direct.
The technical program has been strengthened the effect of heat loss through radiation, the carbon dust radiation paint directly is coated on the LED wiring board, and in conjunction with the saturating characteristic of infra-red radiation of glass, make the light fixture (fluorescent lamp, bulb lamp etc.) that huge difference and good heat dissipation effect are arranged with traditional LED light fixture, greatly expanded range of application and the applicable situation of LED light fixture.
The nano carbon microsphere shell is sealing Multi-layer graphite structure, can be at 3D direction infrared radiation outwardly.
The nano carbon microsphere particle is made an addition in the resin, make composite granule, and mat static powder body coating mode is coated on metal base (aluminium base, pcb board etc.) surface, can realize the comparatively ideal radiating effect of the technical program.
Experiment shows: the heat radiation coating of adding a small amount of nano carbon microsphere has conduction (antistatic), heat conduction and radiation cooling effect, can be applicable to natural heat dissipation, electrostatic dissipation, electromagnetic shielding and radical protection (corrosion protection) etc.
Carbon clustered materials (black matrix) radiation cooling effect is good.Under uniform temp (90 ° of C), with the observation of infrared ray pickup camera, very red as fire (radiant emissivity reaches 98%) of application arranged, and the significant hypothermal speed, show coating tool radiation cooling effect.This is applied to single 5W LED desk lamp goods, and the LED temperature can be down to 50.8 ° of C by 75.1 ° of C, and brightness increases by 30%, and the life-span can significantly promote.Learn that by experiment in general, the sample of coating nano carbon ball can more identical shaped not application sample cooling reach 6 ° more than the C.
Because the utility model directly is coated on the carbon dust radiation paint on the LED wiring board, adopted the version of strengthening heat loss through radiation, and can be through the characteristic of infra-red radiation in conjunction with glass, guaranteed that radiation paint goes out heat radiation, can be made into the light fixture that huge difference and good heat dissipation effect are arranged with traditional LED light fixture.
The utility model can be widely used in design, the manufacturing field of LED light fixture.
