CONTROL MODULE FOR CONTROLLING A LIGHT, PARTICULARLY A STREET LIGHT, AND NETWORK OF LIGHTS

摘要

Described herein is control module for a street light which is mounted on the street light and provides a control output for controlling the operation of the light. The control module has a circuit board (38) on which a controller (39) is mounted, the controller being connected a long-distance communication module, a short-distance communication module, and a geocoordinate module. A network can be formed by the control modules in which a central server uses long-distance communication for communicating with the control modules at start up and with a group controller after start up, the group controller using short-distance communication for communicating with control modules within its group. A sensor (41) may be provided in the control module for modifying the normal operation of the light in accordance with sensed changes in its local environment.
