Under extremity, indivedual light fixtures are lighted for a long time, and the light fixture that can not exclude these long-term electricity is large-power lamp, but its
Position can not be determined, in order to tackle these individual cases, in traditional loop power supply, and the service cable in all loops will be by
Long-term safety current-carrying considers that i.e. cross-section of cable product is sufficiently large.And the present embodiment is powered using area power, the electricity in a region
Amount is calculated in tens kilowatts of rank, is usually more than ten, or even tens lamps services, indivedual several long-term electricity
Amount, does not result in long-term high current load, theoretically, and block supply cable can be by 30% consideration of maximum output power
Can（Because the probability that light fixture in a region is lighted is very low simultaneously, typically also with regard to 2,3 times, and the time is very short, more more than ten
Second to the rank of tens seconds）.
Using the light electric power system of the present embodiment, by taking the grand theater of Guangzhou as an example, cable is powered mould relative to conventional circuit
Formula can just save=(1-55.6% × 26.5% × 30%)=95.6%.Even if not considering the saving of block supply cable 30%, cable
=(1-55.6% × 26.5%)=85.3% can also be saved.
