Heat-dissipation and insulating ceramic lamp shell body and preparation method thereof

Abstract

The invention discloses a heat-dissipation and insulating ceramic lamp shell body and a preparation method thereof. The lamp shell body comprises a connection lamp holder and a combined type shell body, wherein the combined type shell body is composed of a light-shielding cover and a light-transmission cover; the light-shielding cover comprises an inner-layer supporting shell and a heat-dissipation and insulating shell which is embedded into the outer part of the supporting shell; a heat-dissipation fin is arranged at the outer part of the heat-dissipation and insulating shell; the supportingshell is made of a metal material; an inner wall of the supporting shell is coated with a light reflection material made of a ceramic material. The lamp shell body is prepared through the following steps: preparing the supporting shell; selecting the metal material; stretching and stamping the metal material; processing the metal material to an appointed size for later use; preparing the heat-dissipation and insulating shell; arranging the heat-dissipation and insulating shell which is prepared in advance on the outer part of a heat-conducting medium layer in a sleeving manner; spirally arranging the light-transmission cover which is prepared in advance on a lower opening thread of the supporting shell to prepare the lamp shell body. A production technology of the lamp shell body is simpleand convenient and the cost is low, so that the lamp shell body has relatively high practical value and a wide market prospect.

[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, low heat resistance, so the service life is short; (2), used for ceramic lamps There is a circuit inside, and the aging and water seepage of the green body will easily cause short circuit failure of the internal circuit; (3), it is located outdoors, and because the porcelain is fragile, it needs ceramic lamps with high strength and anti-seismic performance; (4), currently on the market as The ceramics of the LED lamp shell 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.
