Description

Automobile halogen bulb with built-in ceramic radiating matrix Technical Field The utility model relates to the technical field of automotive halogen bulbs, in particular to an automotive halogen bulb with a built-in ceramic heat dissipation matrix. Background In an automobile lighting system, a halogen bulb is a common light source for automobile headlamps, tail lamps and other parts by virtue of the advantages of low cost, moderate brightness and the like. In automotive lighting systems, conventional halogen bulbs generate a large amount of heat when the filament continues to emit light and heat during use. Due to the lack of an efficient heat dissipating structure, this heat is difficult to dissipate rapidly, resulting in excessive internal bulb temperatures. The high temperature not only accelerates the oxidation and loss of the filament and shortens the service life of the bulb, but also can lead the glass shell of the bulb to be broken due to thermal stress, therefore, we propose an automobile halogen bulb with a built-in ceramic heat dissipation matrix. Disclosure of utility model The utility model aims to provide an automobile halogen bulb with a built-in ceramic heat dissipation matrix, which aims to solve the problems that the prior halogen bulb lacks an efficient heat dissipation structure, and the heat is difficult to quickly dissipate, so that the internal temperature of the bulb is too high.
