switch control photocell sensor

Photocell is born v effect using light convert light directly into electrical energy device. Because it is the solar direct substation can be, also known as the solar cell. It is made based on light born v effect, is the power type active element. It has a rather of large-area p-n junction, when light on the PN junction, the knot the ends of the electromotive force.

Name: the name of the semiconductor materials of the photocell crown light before the battery (or solar cells). Such as, selenium cell, such as gallium arsenide photovoltaic cells, silicon photocell. At present, the most widely used, the most promising is silicon photocell.

Silicon photocell is cheap, high conversion efficiency, long life, suitable for receiving infrared light.

Selenium cell photoelectric conversion efficiency is low (0.02%), short service life, suitable for receiving the visible light response peak wavelength (0.56 microns), the most suitable for manufacturing of illuminance mete

· Street way Lighting
· Building Perimeter Lighting
· Outdoor Advertising Signs
· Parking Lot Lighting

Meet stringent utility standards for street& highway lighting.
· Delayed response prevents false switching due to light from vehicles, lightning, etc.
· Longer life extends the maintenance cycle for photocontrols mounted in difficult locations.
· Positive electronic switching provides quick made/break of the load relay eliminating relay chatter
· Regulated voltage and silicon photocell maintain accurate turn on /off points of the life of the control
· Low power consumption through a unique regulator circuit. Resulting low internal temperature rise contributes to long life.l For safety reasons, the RYG photocontrols are designed to fail in the ON position
