- The optical controller is a kind of three-terminal device which includes the light sensing element and the relay. Common optical switches contain a normally closed electrical contact.
- light control is generally used for the management and control of environmental brightness according to the use of AC outdoor lighting. With the expansion of application areas,
- but also for other electrical AC power management. Such as curtains and so on. The zero line of the input lamp of the controlled fixture is connected in a conventional manner,
- and the phase line is connected to the AC power supply via the optical controller.
- In common applications,, the optical sensor senses the ambient brightness is lower than the safety value, the phase line connected to the controlled lighting to start to supplement the lighting;
- when the ambient brightness is higher than the predetermined value, the phase line Disconnected, so that the controlled lamps lose power and turn off.
