Abstract
The invention discloses an LED (Light-Emitting Diode) lamp housing with an anticorrosive, heat-dissipation, high-insulation ceramic thermal spraying mode. The LED lamp housing comprises a metal housing and a ceramic coating which is coated on the surface of the metal housing, wherein the surface of the metal housing is provided with a rough surface layer which is formed by removing an oxide layer through polishing; and the ceramic coating is coated on the rough surface layer. The technical scheme is adopted, the LED lamp housing with the anticorrosive, heat-dissipation, high-insulation ceramic thermal spraying mode has strong bonding force of the metal and the ceramic coating, so that the lamp housing has anticorrosive performance, heat dissipation and high-insulation performance, improves environment resistance, can be applicable to illumination in various bad environments, has a longer service life, and is more applicable to streetlamps, landscape lamps, coastal dock lamps and various outdoor lamps. Meanwhile, the manufacturing process is simple, the manufacturing cost is low and the production efficiency is high.
Description
Technical field
The present invention relates to the LED lamp outer casing of the high insulating ceramics thermal spraying of a kind of anticorrosion heat radiation pattern.
Background technology
Light emitting diode (LED) is as a kind of novel luminescent device, have the plurality of advantages such as energy-saving and environmental protection, long service life, toggle speed are fast and have development prospect, but because of LED very responsive to temperature, the too high meeting of junction temperature causes LED luminous efficiency fast reducing, the service life of significantly reducing LED.So LED light fixture fibrous root is according to the supporting good heat-dissipating casing of watt level or heat sink heat sink strip.
Traditional LED lamp radiating shell is with plastics or metal material carrier and the radiator as the light source luminescent body.The plastics material has good insulating properties, and light, but heat radiation is slow, and when the temperature of large-power lamp raise fast, the plastics material can't the Quick diffusing heat, affects service life.The metal species material, it has the good capacity of heat transmission, easily processing, outward appearance is generous, but poor insulativity is directly exposed in the air after the processing of metal lamp outer casing and uses, and easily produces oxidation, not only reduces radiating effect, also affected attractive in appearance simultaneously.
Produce its radiating effect of oxidation affects and attractive in appearance in the air in order to prevent that metal material is directly exposed to, make it more attractive in appearance at the lamp housing surface various resin materials of coating and color, but metal shell is wrapped in the cold coating, the amount of heat that wafer produces just can not effectively shed, and reduces the service life of wafer.
In order to reach better radiating effect, can in cold coating, add the heat sink material coating, but also have the thermoresistance layer of surface resin coating, affect radiating effect.
In sum, existing lamp outer casing respectively has pluses and minuses.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide the LED lamp outer casing of a kind of corrosion-resistant, easy heat radiation, good insulation preformance.
In order to reach above purpose, the technical solution used in the present invention is: the LED lamp outer casing of the high insulating ceramics thermal spraying of a kind of anticorrosion heat radiation pattern, it comprises metal shell, is coated in the ceramic coating of described metal shell surface, metal shell surface has economy-combat and grinds off the flocked layer that forms behind the removing oxide layer, flocked layer forms through mechanical hacking or pressure air sand washing by the surface at metal shell, and ceramic coating adopts the mode of thermal spraying to be coated on this flocked layer.The thickness of ceramic coating can be regulated according to specification requirement.Metal shell can be the metal lamp outer casing of various shape and size sizes, also can be heat dissipation metal bar or heat sink.
Further, the material of ceramic coating can be preferably aluminium oxide ceramics.
Owing to adopt technique scheme, the LED lamp outer casing of the high insulating ceramics thermal spraying of the anticorrosion heat radiation of the present invention pattern, metal shell surface forms flocked layer and forms the ceramic coating that one deck is combined closely with metal through ceramic thermal spray again after polishing, metal and ceramic coating adhesion are strong, make lamp outer casing have anticorrosion, heat radiation, high insulating property, improved anti-environmental performance, applicable to the illumination in the various adverse circumstances, longer service life more is applicable to street lamp, Landscape Lamp, coastal dock lamp and all kinds of outdoor lamp.Simultaneously, preparation method technique is simple, and cost of manufacture is low, and production efficiency is high.
Description of drawings
Accompanying drawing 1 is the structural representation of the LED lamp outer casing of the high insulating ceramics thermal spraying of the anticorrosion heat radiation of the present invention pattern.
Number in the figure is:
1, metal shell; 2, flocked layer; 3, ceramic coating.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Can find out from the structural representation of accompanying drawing 1, present embodiment provides the LED lamp outer casing of the high insulating ceramics thermal spraying of a kind of anticorrosion heat radiation pattern, it comprises metal shell 1, is coated in the ceramic coating 3 on metal shell 1 surface, metal shell 1 surface has economy-combat and grinds off the flocked layer 2 that forms behind the removing oxide layer, and ceramic coating 3 is coated on this flocked layer 2.
Metal shell 1 can be the metal lamp outer casing of various shape and size sizes, also can be heat dissipation metal bar or heat sink, the surface of metal shell 1 is removed metal oxide film by mechanical hacking or pressure air sand washing and is formed flocked layer 2, its method is for to be fixed on metal shell 1 on the sand washing frame, with the sand washing of sand-blasting machine pressure air or mechanical hacking, obtain flocked layer 2 thereby remove metal oxide film.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
