Abstract
An intellectual lamp unit able to be installed on a conventional lamp socket controlled by a wall switch includes a bypass connected in parallel with a wall switch and provided with a resistance or a diode for producing potential difference or power phase difference when the wall switch is turned off. An intellectual lamp to be installed on a conventional lamp socket consists of a lamp main body disposed therein with a power processing circuit, a detecting switch, a charging circuit, a charging battery, a driving circuit, a microprocessor and a lamplight source. When the wall switch is turned on or off under the condition of normal power supply, the lamplight source can be controlled to produce or extinguish lighting, and during blackout, the lamplight source can be started to produce emergency lighting immediately, supplied with power by the charging battery.
