gridComm, a leading supplier of smart street light solutions and networks for pan-city connected IOT sensors, today announced availability of its family of smart street light digital power supplies that power LED street lights and create a street light network for remote monitoring and control.
The gridComm digital power supplies (DPS) combine its digital power supply technology with its proven reliable, high noise immunity data communications, enabling remote control and monitoring of street lights. The DPS (a.k.a. Smart Driver) is also integrated with metering functions for real-time monitoring of operational status, power consumption, current, voltage, and power factor of individual street lights. This tremendously increases efficiency by reducing needs for manual checking of lights and facilitates timely repairs of faulty lights. Besides, the DPS is designed and built with lesser discrete components as compared to the conventional fixed-topology drivers. This results in much higher reliability and performance. Power efficiency is as high as 95% with a power factor of 0.95. The DPS implements a 32-bit MCU-enabled control feedback loop at the front-end driver circuitry. Due to its programmable nature, the DPS is able to adapt to different types of loads with simpler circuit design at a lower cost. The MCU also enables it to perform Machine Learning and compensate for any DC voltage drifting or power variations due to faulty LEDs, hence preventing the lamp from flickering or premature failure.
There are DPS models for 90, 120 and 150-watt street lights. When used with gridComm’s Master Light Controller, and the backend street light management software (SLMS), this forms a complete smart street light control and management system. This enables real-time control and automatic scheduling of switching on and off, and dimming levels of individual lights from a central location, reducing electricity usage by up to 40%.
eSpot will manufacture and sell the DPS’s for use in smart street light deployments. Working with Watran on high volume manufacturing, quality control and improved reliability, eSpot will provide DPS’s in large quantities.
“gridComm smart street light digital power supplies enable cities to remotely monitor and control a network of street lights. Being able to communicate data from street lights reliably is critical. This is difficult in electrically noisy environments. These digital power supplies power the lights, and enable reliable communications for improved maintenance and reduced cost, critical requirements towards building smart cities,” said K. H. Jen Managing Director, gridComm. “Working with eSpot enables us to meet the high-volume requirements for smart city street light deployments”.
“gridComm’s smart street light solution is used in smart cities throughout Asia. With eSpot manufacturing and light driver quality management, we will be able to provide smart street light solutions for large quantity street light deployments,” said Ricky Cheung, eSpot CEO.
