LIGHTING APPARATUS USING PN JUNCTION LIGHT EMITTING MEANS

摘要

PURPOSE: A lighting device using a PN junction light emitting device is provided to reduce manufacturing costs without an additional driving substrate by integrating a PN junction light emitting device and a switch with a power transmission substrate. CONSTITUTION: A power transmission substrate(21) includes a metal layer, a wiring layer, and a connector. The wiring layer includes a wire and an insulation layer which insulates the wire. A connection cable applies power to the connector. A first switch(63) is connected between a first group(G1) and a second group(G2). A second switch(65) is connected between the second group and a third group(G3).
