Problems solved by technology

[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 in ceramic interiors There is a circuit, 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 requires ceramic lamps with high strength and shock resistance; (4), currently on the market as LED The ceramics of the lamp shell are mainly alumina ceramics and steatite ceramics. 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.
