Introduction
Shanghai Long-Join Intelligent Technology Inc. has been a verified custom manufacturer on Alibaba for about 17 years and has 225 staff members. They deal in lightning and photocells products including NEMA Series of Photocells, Zhaga Series of Photocells and Twist-lock Photocell/Photocontrol. They ranked 6 in on-time delivery of Lightning products and have customers internationally in Europe, North America, Central and South America and Asia.
A photocell is a new technology which is also known as a Photo controller. This device detects light and sends signals to the device to which it is connected. Outdoor photocells are the light sensor for outdoor lighting which detects daylight and turns off automatically and when it is nighttime the sensor sends the signals to the device to turn on the lights. This is a reliable device for the streets and home.
How does it work?
It is all about the detection of light. When the photocell detects the proper light it sends the signal to the light fixture to turn off. At nighttime, when it detects the light is low it again sends the signal to the light fixture to turn on. So, you do not need to worry about turning on and off the lights.
How to use it?
Simply connect the photocell to the light fixture and it will automatically work by detecting the light. The people who have a memory of goldfish or are busy in their work use photocells with the light fixture.
Which one to buy?
Make sure when you are purchasing the photosensor then its wattage rating matches the wattage of the bulb you are planning to use. Choose the waterproof, reliable and adjustable photosensor to get a better outcome from the lighting setup that saves you money and energy at the same time.
Application of Photocell in Outdoor Lightening
1. Outdoor Street Lighting
Application: Photocells in the lights are used for the automatic operations of streetlights at day and nighttime. It all depends upon the ambient levels of light at dusk and dawn.
Type: Single-point and simple photocell sensors are used with the light fixture of streetlights for on/off control.
2. Smart Street Lightening
Application: In smart street lighting, the photocells work as an interconnector between sensors and controllers. They are used for remote monitoring, saving energy and on/off streetlights according to the levels of lightning.
Type: The more advanced technology is used for smart street lighting. For this purpose, Zhaga-D4i-compliant sensors are the best choice. They are reliable in real-time events like traffic patterns and weather conditions because these sensors work on the commands of the central control system by communicating the lightning data.
3. Area Lighting
Application: Areas like plazas, parks, roads and buildings require photocell sensors to ensure that lightning is triggered when needed and turned off at day time to save energy and money.
Type: The photocells used in area lightning vary in size and can be basic or sophisticated. It all depends upon the design requirements of lightning, energy saving and voltage of photocell and light fixtures.
4. Parking Lot Lighting
Application: The parking lots provide safety to vehicles, so, clear lighting is required for security purposes at nighttime. Photocells are used in the parking lot for energy saving during the daytime and provide excellent lighting at night.
Type: Occupancy sensors and lightning sensors are used in the parking lot, and they activate when they detect the light and movement of the vehicle. This combination saves the cost and energy and provides better security to vehicles.
Main Products
Zhage Series of Photocell
Zhaga-D4i
This is developed by Zhaga Consortium. It is the innovation in the lighting industry which interfaces between LED luminaires and other lighting components. One of the key components of Zhaga-D4i is that it is a future-ready smart device with a wireless lighting network.
It is an extension of the Zhaga Book 18 standard. In outdoor luminaries, it worked as a communicator between mechanical and electrical lines. It is used for outdoor and street lighting purposes.
Zhaga Socket
It is a connector or receptacle used for outdoor lighting. It connects the sensors, and modules communicate properly. It works as an interface with other Zhaga-compliant components such as LED modules or drivers. It is an innovative product which does not require any wiring or complex installation system. These are part of Zhaga base specification which include Book 7 or Book 20.
Zhaga Cover
It is the case design element used to protect LED lighting sources. They provide both mechanical and thermal protection to the Zhaga-compliant components. The purpose of these covers is to protect the LED light system outdoors and streetlighting against environmental conditions like moist weather or dust.
Zhaga Shell
It works the same as the cover by protecting the LED system against environmental conditions. Its use varies depending upon the application and Zhaga base standard use along with it.
Zhaga Base
It was developed by Zhaga Consortium and has mechanical, thermal and electrical characteristics to use in LED fixtures. These bases include standards like LED modules (Book 7) and outdoor lighting with sensor and communication interface (Book 18). These components are interoperable.
NEMA Series of Photocells
NEMA 3-Pin Socket (NEMA 5-15R)
It is a standard socket with two flat pins and one round ground pin and it is used in households in North America. It is not typically used for photocells because it is a general electrical device but still, it has demand varies on the size of the photocell.
NEMA 5-Pin Socket (NEMA L5-15R)
It is the socket having two hot pins and two neutral pins. There is also one ground pin and it is widely used on the industrial side and with photocells.
NEMA 7-Pin Socket (NEMA 7-15R)
The socket includes three hot pins, three ground pins one neutral pin. It is a long long-lasting device used to attach photocells with the light at the hazardous location.
Conclusion
Photocell is the main source of energy and money saving by attaching it to the lighting fixture. Long-join is the manufacturer of photocells and provide the custom products internationally. This article is the guide for the industry professionals for the importance of photocells in the outdoor lighting on streets, parking lots and other areas where remote control modules can be used and Long-join are providing series of NEMA and Zhaga photocells all around the world.
