Power reduction system for discharge lamp, has control module with relay whose contacts short circuit coil windings based on measurement of stress in network, current absorbed by lamp, and time table
Power reduction system for discharge lamp, has control module with relay whose contacts short circuit coil windings based on measurement of stress in network, current absorbed by lamp, and time table
The system has an additional coil (1) inserted into multiple receptacles in series with a ferromagnetic ballast (2) that feeds a discharge lamp (7). A control module (3) has a relay whose contacts short circuit windings of the coil based on measurement of stress on an electrical distribution network, a current absorbed by the lamp, and a time table selected by programming straps.
