Automatically turn on- turn off work principle for twist lock photocell

Simple word: automatically turn on or turn off switching according ambient lighting level. Essential on-off switch work mode by LDR (light dependent resistor) and light sensor will perfectly control turn on at dusk and turn off at dawn. Therefore, our photocell switch control by built in light dependent resistance, LDR resistance value decrease or increase according around lighting area level to regularly automatically on-off control lighting.

Twist lock photocell control built electric circuits work component

Photocell is a device in the form of an electronic circuit that functions as a circuit breaker or connecting electric current that works automatically in accordance with the LDR Value change.

Our electronic photocontrol product is designed with electronic circuits with sensor of photodiode and a surge arrester (MOV) is provided. Therefore, it’s work principle in accordance with light sensor, or not LDR related.

You should know about electronic photo control circuits component in OEM-ODM design to help me reduce purchase cost and increase shopping succeed.

>> Support ODM / OEM light sensor by ambient lighting level, such as Cadmium Sulfide Photocell, IR Filtered Phototransistor, Unfiltered Phototransistor.

>> Available custom arrester capacity，such as 110J/3500amp, 235J/5000amp, 460J/10000amp etc.

>> Relay options, 10Amp, hi-power version 20Amp (JL-207C-HP),

>>Waterproof rating, IP54, IP65, IP66

>> your different select work mode, fail on photocell, fail off photocell sensor.

>>preset time delay, avoid to abnormal light project on photocell lens, in order to protective light fixture use around lifetime. Further, factory preset 5-20 seconds time delay for turning-off might avoid mis-operation due to spotlight or lighting during the night time.

Not only get know electronic photocontrol circuits component, but also you need extra function with twistlock photocell cover. Our inter-locking base / shell design for friendly environmental housing. High temperature base with PBT material, rated at minimum 138℃, along with a UV stabilized, opaque housing ensure our control will last over 10 years without degradation.

Pay attention to tips: Do not install the control unit in a place extremely dark in daytime or a place directly by lighting of turning on lamp.

Where is the sensor on a street light?

For Most street lights have a light sensor mounted on top. It’s a cylindrical box that can easily be seen in the daylight if you look for it. The purpose of the sensor is to automatically turn the light off during the day and turn it on again at night.

How do automatic street lights work?

when light shines on the photocell, it turns the transistor on, which energizes the relay’s electromagnet, which turns the light off at daylight. When it is dark, the photocell with light dependent resistance for decrease value, so current flows through the base and the relay is activated the light on.
