Abstract
The invention discloses a touch type delay street lamp which is characterized by being composed of 220V alternating current, a full-bridge rectifier circuit, an illuminating lamp HL, a 12V stabilized voltage supply, a working state indication circuit, a touch signal amplification circuit, a unidirectional thyristor trigger circuit and a unidirectional thyristor control circuit. The acoustic control delay illuminating lamp in the market is convenient to use and can achieve the purpose of saving energy, but is usually counterproductive due to the fact that the acoustic control delay illuminating lamp is very sensitive and acts as long as the periphery has slight sound, accordingly electricity cannot be saved, and service life of an incandescent bulb is affected due to frequent lamp triggering and lighting; and a user has to make sound to lighten the acoustic control delay illuminating lamp especially when the user goes back home at night, and sleeping of surrounding neighbors can be disturbed. In order to overcome the defects of the acoustic control delay illuminating lamp, the touch type delay street lamp is changed from acoustic control to touch control and is good in effect proved by practical use.
Description
