Smart Lighting System Overview
The Smart Lighting System collects data from and manages the operation of remote street luminaires. The
System consists of the following components:
• LCU – Located on top of or inside the luminaire cover, or in the light pole, the LCU sends sensor data
and executes scheduled and unscheduled luminaire control commands, such as on/off and dim,
received from the CMS Application Server.
• DCU Gateway – Network gateway between LCU and CMS transmits luminaire data and luminaire
control commands.
• CMS – Web-based backend application server provides real-time management: receives LCU
communications from the DCU and sends luminaire control commands to the DCU for transmission
to LCUs.
CMS usually contains a database of static and dynamic LCU information: ambient light values, lighting
and dimming schedules, power usage, status, etc.
