description The utility model relates to an improved electric transformer, which comprises a primary side three phase coil winding and a secondary side three phase coil winding, wherein three taps a1, b1, and c1 are added to the secondary side three phase coil winding, and the numeric range of the output line voltage ua 1, ub 1, and uc 1 of the taps a1, b1, and c1 is from 350 V to 370 V. Due to the fact that the taps of which the output line voltage is lower than the standard output line voltage of a secondary side are arranged on the secondary side three phase coil winding of an existing power transformer by the utility model, the utility model can provide a lighting source with electrical source voltage which can make the lighting source have electricity saving effect and extend the service life of the lighting source. Due to the fact that the utility model only needs to add the three taps to the secondary side three phase coil winding of the existing power transformer, the functions of saving electricity of a lighting system can be realized, and the utility model has characteristics that the utility model does not need to purchase equipment and occupy the space in addition.
