Abstract
The present disclosure discloses a lighting apparatus using a PN junction light-emitting element, the apparatus including: a power transmitting substrate having a plurality of boundaries defined thereon; a plurality of PN junction light-emitting elements positioned within each boundary and divided into a plurality of groups; and a first switch provided on the power transmitting substrate, wherein the first switch goes into the ON state by a supplied AC having a first voltage to cause PN junction light-emitting elements of a first group positioned within each boundary to emit light, and the first switch is in the OFF state when PN junction light-emitting elements of a second group, which is positioned within each boundary and connected in series to the first group, emit light by a supplied AC having a second voltage higher than the first voltage.
