Wiring Type and Screw-lock Type of Photocell

The photocell is a device that can adjust the opening and closing of lamps according to the brightness and darkness of the surrounding light, mainly including five types: wired type, screw-in type, socket type, lamp head type, and screw-lock type.

There are two main types of photocell currently used in RZ: wiring type and screw-lock type.

Wiring type:

The wired type is suitable for automatic switch control of lighting fixtures. such as garden lights, corridor lights, door lights, etc., this kind of light controller can realize the control function of day and night according to the change of light intensity in nature, this kind of light controller is designed based on micro-electric thermal structure, contains an ambient temperature subsidy mechanism and the work is not affected by the change of ambient temperature, and at the same time, this kind of light control has a delay of 30 to 120 seconds to maintain the function of working state, when the ambient brightness at night changes briefly under the interference of car lights, lightning and other factors, Damaging switching of controlled luminaires can be avoided.

Screw-lock type:

Screw-lock type is suitable for automatic switch control of street lights, garden lights, corridor lights, and other lighting fixtures. This type of photocell can realize the control function of day and night according to the change of light intensity in nature. This kind of photocell is designed based on electronic circuits, the switching delay is short, it can filter the occasional bright light interference at night, and it is convenient for testing and maintenance.
