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 [0001] The invention involves an LED lamp shell with an anticorrosive heat dissipation high insulation ceramic hot spray mode. Background technique [0002] As a new type of light -emitting device (LED), it has many advantages such as energy saving, environmental protection, long service life, and fast startup speed. However, because LED is extremely sensitive to temperature, too high knot temperature will cause LED luminous efficiencyFast reduction, greatly reduced the service life of LEDs.Therefore, LED lamps must be equipped with a well -equipped heat dissipation shell or heat sink heat dissipation bar according to the power size. [0003] The traditional LED lamps are plastic or metal materials as the carrier and heat dissipation of the light source luminous body.Plastic materials have good insulation and lightweight, but slow heat dissipation. When the temperature of high -power lamps rises rapidly, plastic materials cannot quickly emit heat and affect the se...

AI Technical Summary

Problems solved by technology

Plastic materials have good insulation and light weight, but the heat dissipation is slow. When the temperature of high-power lamps rises rapidly, plastic materials cannot dissipate heat quickly, which affects the service life

Metal materials, which have excellent thermal conductivity, are easy to process, and have a generous appearance, but have poor insulation. Metal lamp shells are directly exposed to the air after processing, and are prone to oxidation, which not only reduces the heat dissipation effect, but also affects the appearance.

[0004] In order to prevent the oxidation of metal materials directly exposed to the air and affect its heat dissipation effect and appearance, various resin materials and colors are coated on the surface of the lamp housing to make it more beautiful. However, the metal shell is wrapped in resin coating, and the large amount of heat generated by the chip cannot be effectively dissipated, which reduces the service life of the chip

[0005]In order to achieve a better heat dissipation effect, heat dissipation materials will be added to the resin coating, but there is still a thermal resistance layer of the resin coating on the surface, which affects the heat dissipation effect
