Abstract
The utility model discloses an LED (light-emitting diode) bulb lamp with a novel radiating structure, comprising a lamp socket, an insulating drive housing, a drive power supply, a power supply cover, a radiator, a light source and an insulating lampshade, wherein one side of the radiator is connected with a fan via a bolt, and the other side thereof is installed with a light source; and a flow guide plate is further disposed between the fan and the radiator. The flow guide plate and the fan are orderly connected to one side of the radiator via bolts, radiating efficiency is increased by the principle that the fan forces convection, and hot air backflow can be prevented and air flow in the radiator can be guided via the flow guide plate. Compared with the prior art, a fan radiating system is added in a lamp body, so that the lamp body temperature and LED junction temperature of the LED bulb lamp can be effectively decreased, influence on LED luminous flux by heat can be reduced, light attenuation can be slowed down, and the life of the lamp can be increased. The LED bulb lamp has the advantages of being simple in structure, good in radiating effect and prolonged in service life.
