Most of the reasons for turning on the toilet light at night in a hotel are safety. If the hotel is not a carpeted room and uses floors and planks, then sleeping with the lights on at night is also for personal safety. If there is no light in the room at night, it is easy to fall. >>>More
After the 220V AC power passes through the bulb H and the rectifier bridge, it becomes a DC pulsating voltage, which is added to the VS and R branches of the thyristor as a forward bias voltage. During the day, when the brightness is greater than a certain extent, the photodiode D presents a low-impedance state of 1K, so that the triode V is cut-off, and its emitter has no current output, and the unidirectional thyristor VS is blocked because there is no trigger current. At this time, the current flowing through the bulb H does not emit light. >>>More
1. Voice-activated lights and touch-type sensor lights should not be used, because they are automatically turned off within a certain time range, in case the work is not done over there, there will be some small troubles, and the electrician will be scolded. >>>More
The circuit must be a circuit in order to be energized.
The switch is in charge of the circuit, and if it burns and causes a closed circuit, then of course your lights can't be turned off. >>>More
