Production process of LED streetlamp shell

Abstract

The invention discloses a production process of an LED streetlamp shell. The production process includes the steps of producing a combination shell; producing a light-permeable shade; producing a connection holder; assembling the combination shell, the connection holder and the light-permeable shade. The step of producing the combination shell specifically includes: (1) producing a support shell;(2) producing a heat-dissipating insulating shell; (3) applying a reflecting layer; (4) butting and fitting the shells. The production process herein employ a ceramic material and the metal support shell to produce the LED streetlamp shell; assembly efficiency can be greatly improved; the ceramic shell has bright glaze that rarely fades in light and rain; the glaze has great wind resistance and certain corrosion resistance; the glaze insulates heat and electricity; the production process is simple, is low in cost, and has high application value and a promising market prospect.

Description

technical field [0001] The invention belongs to the technical field of ceramic lamps, and in particular relates to a preparation process of an LED street lamp shell. Background technique [0002] Ceramic material as the heat dissipation shell of LED lamps is a heat dissipation material that has emerged in the past two years. With the invention of science and technology, ceramic technology has become increasingly mature. Outdoor ceramic lights made of ceramics are not only beautiful and practical, but also have a high artistic quality. Value, (1) The ceramic lamps made by the existing formula are mostly suitable for indoor use, with poor weathering and aging resistance, acid and alkali resistance, and low heat resistance, so the service life is short; (2) Used for Jun porcelain There is a circuit inside the lamp, and the aging and water seepage of the green body may easily cause short-circuit failure of the internal circuit; (3), located outdoors, and because the porcelain is...

[0002] Ceramic material as the heat dissipation shell of LED lamps is a heat dissipation material that has emerged in the past two years. With the invention of science and technology, ceramic technology has become increasingly mature. Outdoor ceramic lights made of ceramics are not only beautiful and practical, but also have a high artistic quality. Value, (1) The ceramic lamps made by the existing formula are mostly suitable for indoor use, with poor weathering and aging resistance, acid and alkali resistance, and low heat resistance, so the service life is short; (2) Used for Jun porcelain There is a circuit inside the lamp, and the aging and water seepage of the green body may easily cause short-circuit failure of the internal circuit; (3), located outdoors, and because the porcelain is fragile, ceramic lamps are required to have high strength and shock resistance; (4), currently on the market The ceramics used as the shell of LED lamps are mainly alumina ceramics and steatite porcelain. Ceramic materials can effectively solve the heat dissipation and insulation problems of LEDs

Alumina ceramic materials have high density, expensive raw materials, firing temperature above 1600 degrees, long firing cycle, and cannot be mass-produced. Although the thermal conductivity is high, the manufacturing cost is too high and the product is too heavy

Talc porcelain has low thermal conductivity. Although the production cost is low, it can be mass-produced, but the thermal conductivity is too low and the heat dissipation is not good. Only low-power LED lamps can be produced.
