PROBLEM TO BE SOLVED: To provide a lighting apparatus in which wasteful power consumption is suppressed and extra heat radiation countermeasures are not required.SOLUTION: A DC/DC converter 33 converts DC voltage output from a rectification circuit 32 into a required DC voltage. A PWM control circuit 34 controls electric power supplied to an LED module 42 by performing pulse width modulation to the DC voltage output from the DC/DC converter 33. A solar battery 70 converts light from the LED module 42 into electric power, and supplies the converted electric power to a control part 60 (a microcomputer for control 61 and a memory 62). The microcomputer for control 61 obtains a signal output by a remote control light-receiving part 45 and outputs a control signal to the PWM control circuit 34 based on the obtained signal. |
