Abstract
The utility model disclose a hand touch type time-delay street lamp, which is characterized by comprising a 220V alternating current, a full-bridge rectifier circuit, a lamp HL, a 12V voltage stabilizing power supply and working state indicating circuit, a touch signal amplification circuit, a unidirectional thyristor trigger circuit, and a unidirectional thyristor control circuit. A voice-activated time-delay lamp at the market is truly convenient in use and can achieve the purpose of saving energy. But sometimes the voice-activated time-delay lamp can not realize what people want. As the voice-activated switch time-delay lamp is substantially sensitive, the voice-activated time-delay lamp activates as long as a sound exists around, and then energy consumption can not be saved and the service life of the lamp bulb due to frequent lighting is further affected; especially when people go back home at midnight, the voice-activated lamp can only be turned on when a sound is made, which does affect sleep of neighbors around at night. To overcome the defect of the voice-activated time-delay lamp, the hand touch type time-delay street lamp disclosed by the utility model changes the voice-activated way into a hand touch way, and does have a good effect after practical use.
