Abstract
The invention discloses an LED bulb. The LED bulb adopts the structure that an LED substrate is connected with an inner-wall radiator and a bottom radiator; heat generated by light sources is conveyed to the radiators via the LED substrate; after heat is transferred to radiating fins on the radiators, heat exchange occurs between the heat and cold air around the radiating fins; the cold air is supplemented by openings formed at the lower parts of both the radiators and the openings; the cold air expands when being heated to generate ascending air current to be discharged from heat dissipation holes of a lamp socket; meanwhile, as micro-fans are arranged, air circulation is further sped up to enable the light sources to be cooled down quickly, and accordingly, the problems of light decay acceleration and light extraction reduction, caused when a semiconductor light source works in a high-temperature environment, are effectively solved; and as the radiators are arranged inside, and a drive power supply is wholly placed in a heat radiation passage of the radiators, not only is product miniaturization facilitated, but also the drive power supply can achieve effective heat radiation in the open work environment, the service life of components in the power supply is prolonged and the service life of a lamp is prolonged accordingly.
