Abstract
The invention belongs to the field of lamp circuits, and particularly relates to an induction lamp circuit and a lamp. When a human body inductor U1 inducts a human skin, a triggering pulse is sent to a switching tube to enable the switching tube to be conducted, a relay K1 is thus conducted, a normally open switch S1 of the relay K1 is pulled and a lamp is thus lit. When the human body is away from the induction region, the triggering pulse inducted by the human body inductor U1 disappears, an RC circuit provides a given voltage to the control end of the switching tube for enable the switching tube to be conducted, discharge duration is determined according to the RC value, when voltage drop of the RC circuit is lower than the conduction voltage of the switching tube, the switching tube is cut off, a coil of the relay K1 is out of power, the normally open switch S1 of the relay K1 is opened, and the lamp is extinguished. Thus, noise is not generated, touch control is not used, and the use is extremely convenient.
