<p>PROBLEM TO BE SOLVED: To reduce the influence on a power supply by a relatively simple configuration, in a configuration pulse-driving light-emitting modules that are serially connected.SOLUTION: A lighting fixture 100 includes a power supply 210 including a constant current source 212 and a driver 214 for periodically interrupting a current outputted from the constant current source 212, and a first light-emitting module 230_1 and a second light-emitting module 230_2 that are connected in series to the power supply 210. Each of the first light-emitting module 230_1 and the second light-emitting module 230_2 includes a light-emitting element. A control circuit 232_1 switches a corresponding parallel path 233_1 from a conduction state to a non-conduction state after first time elapses from starting current supply to the first light-emitting module 230_1.</p> |
