Abstract:
According to one embodiment, an LED lamp includes a housing, a base, an LED module, an LED lighting circuit board, and a globe. The base is attached to one end of the housing, and is supplied with electric power. The LED module is attached to the other end of the housing, and is equipped with LEDs. The LED lighting circuit board is accommodated in the housing, and the LED lighting circuit board is equipped with a lighting circuit. The globe covers the LEDs, and diffuses and radiates light emitted from the LEDs, and is attached to the housing. The housing is formed of resin having high thermal conductivity containing carbon-based filler. The light emitting module is attached to the housing through a heat transfer plate a part of which is exposed from the housing.
