Digital Control Turns On the Lights
Oct 1, 2005
The goal of power management for lighting is to ensure that electric lights are switched off or dimmed at times when they are not needed. These times are when people are not present in a particular area or when sufficient or partial natural light is available. Fluorescent light sources are used predominantly in office environments and, by means of suitable solid-state control gear, can be dimmed to any level from 100% down to less than 5% of maximum light output or can be switched off altogether....
