Abstract
A lamp incorporating one or more safety features for reducing the risk of fire or heat damage associated with improper operation of the lamp. One safety feature can be an automatic safety switch for terminating power to the lamp when the lamp is not in a proper operational orientation. The switch is mounted on the underside of the base of the lamp and only provides electricity to the lamp when the weight of the lamp rests properly on its base. A thermal switch which reduces or eliminates power to the lamp when the lamp is operating above a predetermined temperature can be provided, alone or in combination with a light level senor to adjust lamp power in response to room lighting conditions.
