Abstract:
A light-emitting apparatus including a substrate, an LED string mounted on the substrate, the LED string in which a plurality of light-emitting diodes D1-D6 are connected in series, a power supply line 13 (13a, 13b) connected in series to the LED string, and a plurality of protection capacitors C (C1-C5), each being arranged between a connection N (N1-N5) between at least one set of light-emitting diodes in the LED string and the power supply line 13 and having an impedance smaller than an impedance between the connection N and an case ground.
