I: Equipment Introduction
The CH C202 Environmenttal light Monitoring Equipment is independently researched and developed by our company. According to the Tunnel Enterance Part surrounding changing weather conditiond, it cooperates with the intelligent lighting centralized controller to automatically control the power range of the lamps according to the changing of environmental brightness, to achieve the purpose of intelligent tunnel lighting management.
Traditional street lighting, tunnel lighting and industrial lighting such as factory & warehouse lighting Switches Controlling Modes are generally divided into Loop Controlling, Sunrise & Sunset Controlling, the corresponding fixtures Loop Controlling in different time periods, although the controlling is mature and widely used, there are still many problems, such as: it can’t be automatically adjusted Brightness at sunny, cloudy, rainy, sandy, storm and snowing weather with different smart scene lighting modes for safety and more comfortable for the drivers, the adjustment range is fixed (only loop switch); moreover, it is impossible to know the ambient brightness of the project site in time, our intelligent led street/tunnel lighting system provided 8 different lighting scenerio for seamless connecting the exterior surrounding brightness with the interior tunnel lighting bright, or keep the city roads with a constant brightness at any abnormal weather conditions.Cizitens and the drivers can be safe walking and driving at at any suddently changing air conditions. In response to these problems, our company launched this Luminance Collection Equipment,which integrates brightness collection, data processing, and data communication.
The equipment adopts the LORA communication, linked with our centralized controller to achieve auto-dimming.
