摘要： PROBLEM TO BE SOLVED: To provide a light emitting device in which a plurality of light emitting elements differing in driving current are driven by a simple driving circuit and which has high electrical efficiency.
SOLUTION: Main light emitting diodes 7a to 7d and a slave light emitting diode 8a requiring a larger current than the former are connected to a main secondary wiring 2b of a transformer 2 in series, a current detecting resistance 9 detects a main current J2 (≈main current J1), and a control circuit 4 controls the opening and closing time rate of a MOSFET 3 to control the main current J2 to a prescribed value, thereby driving the main light emitting diodes 7a to 7d and slave light emitting diode 8a. Further, the slave light emitting diode 8a is supplied with a slave current L1 which is less than a current needed to obtain a desired light emission output from a slave second wiring 2c, and driven with the salve driving current SJ1 (=J1+L1). The two kinds of light emitting diodes 7 and 8a differing in driving current are driven only by providing one constant current driving circuit to simplify the driving circuit and improve the electrical efficiency.
