Depressor, accumulator is converted into alternating current by inverter and powers for headlamp, due to relatively high to the requirement of brightness in subway station,
It needs many headlamps while illuminating, to cause entire power supply circuit construction complexity, the higher problem of cost, if using
The LED light of direct current 220V, brightness of illumination fully achieves the brightness as exchange headlamp, and no matter whether alternating current has
Electricity can provide illumination, need not use two kinds of lamps and lanterns, but existing ac power supply system cannot be satisfied its needs of powering,
Therefore it is extremely important to design satisfactory power supply system.
