GPRS(2G, 4G) Remote NEMA LED Street Lighting Controller

The NEMA interface wireless single light controller is designed for road and area lighting in smart cities. It has the functions of switching, dimming and monitoring lamps; GPS positioning function; ambient illumination detection and street lamp tilting.The three-primary LED light source is used to reproduce various "natural light" illuminations, with richer chromatograms and softer lighting. Using low-power, high-sensitivity LoRaWAN gateway, and NBIoT, GPRS (2G, 4G) protocols, we can meet most areas of wireless communication.

1.1 Safety Instructions

The following safety principles are followed to ensure personal safety and to help protect the product and work environment from potential damage.





When in an airport or other places, it is necessary to prevent the terminal from causing interference to the aircraft communication system. Ignoring this prompt may lead to flight safety issues and even violations of the law.




When in a hospital or health care places, user need to pay attention to whether there are restrictions on the use of terminal equipment. RF interference can cause the medical device to malfunction, so it may be necessary to turn off the terminal device.




The terminal device does not guarantee an effective connection under any circumstances, and it is necessary to ensure that the device is powered on and in an area with sufficient signal strength.




Terminal device will receive and transmit RF signals when it is turned on. Radio frequency interference occurs when you are near a radio or other electronic device.




Keep the device away from flammable gases. Do not put it near gas stations, oil depots, chemical plants or explosive work site. There are hidden dangers in operating electronic equipment in any potentially explosive atmosphere.

5 Part Description



5.1 GPRS Wireless Module


GPRS module can be used to communicate with the base stations and help to transfer a variety of instructions, such as: switching ON/OFF, dimming commands, uploading power consumption data, uploading illuminance information, etc.



5.2 Control Module


After booting, the module automatically obtains the command sent by the system to start the dimming strategy. If not set, the module will dim according to the factory default strategy.


5.3 Dimming


The product has 1 channel 0-10V analog dimming interface and one channel PWM interface. To better accommodate the needs of multiple LED drivers, the default dimming curve is shown in Figure 5.
