We are Shanghai Long-join Intelligent Co., LTD., we produce the main street lamp light controller in North America. Up to now, we have hundreds of types of light controllers, there are twist-lock type light controllers, button type light controllers, Stem type light controllers, Swivel type light controllers, and so on. In addition, to meet the individual requirements of more overseas customers, we have listed customized products, optical controllers and accessories that meet the local feeling and are delicious. Finally, 20 years of efforts to innovation and development, we have developed compliance to EU standard zhaGA socket, zhaga optical controller, zhaga optical controller accessories, and middle and high end wireless intelligent optical controller switch.

What is a photocell switch?
As we all know, the photoelectric switch with automatic switch function, for instance, an infrared motion sensor switch, microwave sensor switch, and photosensitive switch. And long-join brand factory production of lighting controller belongs to the light-sensitive switch.
Work principle
According the ambient light level, automatically control the lighting of the lamps. usually popular think a sensitivity sensor switch is activated by the light-dependent resistor and light sensor will perfectly control turn on at dusk and turn off at dawn.
A device that detects light. Used for photographic light meters, automatic on-at-dusk street lights and other light-sensitive applications, a photocell varies its resistance between its two terminals based on the number of photons (light) it receives. Also called a “photodetector,” “photoresistor” and “light dependent resistor” (LDR).
How to test the twist lock photocontrol is normal or abnormal？
1. Install the light controller after will clockwise into a 3 pin receptacle product and turn on the power. At first, the light controller will enter the waiting state of initialization and automatic adjustment (preset adjustment activated working, automatically adjusted by the surrounding light intensity, this is a normal phenomenon.), and enter it afterward. Working status.
2. After the installation is completed and the power is turned on, further test whether the on-off of the light controller controls the LED light to turn on and off, and then cover the receiving light source with a black object to determine whether the wiring method is correct, and reliably confirm whether the light controller is malfunctioning .
3. Of course, if you operate by following the requirements of the wiring diagram, you can naturally rule out the wiring fault, to think that the problem occurs at the light control switch.
How to test Stem type photocontrol is normal or abnormal？
1. When the light control is installed and connected to the power supply, the light control will enter the waiting state of initialization and automatic adjustment within about 2 minutes (preset adjustment activated: automatically adjusted by the surrounding light intensity, this is a normal phenomenon.), and then Enter the normal working state.
2. If the transparent window of the probe is covered with black tape or similar material during the daytime test, the Led lamp should Light on after a delay of 30 to 120 seconds. Do not cover the transparent window of the photodetector with your fingers, because light leakage may still make the light control switch keep the Led light off. (The initial test takes 2-3 minutes)
3. After the installation is completed and the power is turned on, further test whether the on-off of the light controller controls the LED light to turn on and off, and then cover the receiving light source with a black object, determine whether the wiring method is correct, and reliably confirm whether the light controller is malfunctioning.
4. Of course, if you were strict to operation in accordion with the requirements of the wiring diagram, you can naturally rule out the wiring fault. otherwise, this question occurs at the wiring method.
How do you know if your photocell is bad?
1. check your wiring photocell, is not by wiring diagram operate.
2. check your install photocell switch operation steps.
3. after mount your photocell on the street light, In the preset adjustment state, please pay attention to observe whether the transparent window flickers normally. If it keeps flickering, the light controller is abnormal.
