<p>PROGRAMMABLE LIGHTING CONTROL SYSTEM A high intensity discharge lamp control system includes a dimming circuit in which each lamp is placed in series with a pair of reactive elements, one of which may be electrically bypassed. A programmable digital microprocessor, synchronized with the phase of the AC power, adjusts the bypass time, thereby providing individual control of the brightness of each lamp. The microprocessor will accept multiple control inputs. Using such inputs, the system may be programmed to optimize lighting conditions at each point in an area to be illuminated while minimizing the electrical energy consumed by the lighting system. The microprocessor may be easily reprogrammed to compensate for changing lighting requirements.</p> |
