LED bulbs for replacing halogen bulbs for automobiles

摘要

The invention relates to an LED bulb used for taking the place of a vehicle halogen bulb. The LED bulb is low power consumption and high-efficiency. Light emitted by the LED bulb can be reflected for expansion, and the externally-irradiated light is maintained within a certain range. The LED bulb comprises: a main body, a light source unit, a housing, and a reflector, wherein the main body includes a plug inserted in a lighting part of the vehicle, the inner side of the main body is accommodated with a PCB; the light source unit is connected with one side of the main body and includes an LED controlled and lit via the PCB; both ends of the housing are made into cut-through cylindrical shapes, one side of the housing is connected with the main body, the light source unit is disposed on the inside of the housing, the inner circumferential surface of the housing has a refractive surface for reflecting the light irradiated by the light source unit; the reflector is connected with one side of the housing to reflect the light transmitted by the light source and the refractive surface, and light is transmitted by a hemispherical reflectance mirror behind the lighting part.
