Abstract
The utility model discloses a thermal spray mode type ceramic LED (light emitting diode) lamp shell with corrosion resistance, heat dissipation and high insulation. The shell comprises a metal shell, and a ceramic coating coated on the outer surface of the metal shell, wherein the outer surface of the metal shell is provided with a rough surface layer which is formed in a way that an oxidation layer is removed by polishing, and the ceramic coating is coated on the rough surface layer. Because of adopting the technical scheme, the thermal spray mode type ceramic LED lamp shell with the corrosion resistance, the heat dissipation and the high insulation, disclosed by the utility model, has strong binding force between metal and the ceramic coating, the shell of a lamp has the performances of the corrosion resistance, the heat dissipation and the high insulation, the environmental resistance is improved, and the ceramic LED lamp shell can be applied to illumination in various environments; the service time is long, so that the ceramic LED lamp shell is relatively suitable for streetlights, landscape lamps, coastal dock lights and various outdoor lamps; at the same time, a manufacture method and process are simple, the manufacture cost is low, and the production efficiency is high.
Description
Technical field
The utility model 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 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 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 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 add the heat sink material coating in cold 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 purpose of this utility model 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 adopted in the utility model 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 after removing oxide layer, flocked layer forms through mechanical hacking or pressure air sand washing by the surface at metal shell, and ceramic coating adopts and the mode of spraying is 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 adopting technique scheme, the LED lamp outer casing of the high insulating ceramics thermal spraying of the anticorrosion heat radiation of the utility model pattern, metal shell surface forms flocked layer and forms the ceramic coating of one deck together with metal is combined closely 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 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 utility model 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 utility model 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 domain of the present utility model is made more explicit defining
Can find out from the structural representation of accompanying drawing 1, the 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 after 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.
Ceramic coating 3 adopts the method for thermal spraying to be coated on flocked layer 2, is closely linked with metal, and metal and ceramic coating adhesion are strong.The material of ceramic coating 3 is preferably aluminium oxide ceramics, and the thickness of ceramic coating 3 can be regulated according to specification requirement.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow person skilled in the art scholar can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
