Title:
LIGHTING DEVICE
Document Type and Number:
Japanese Patent JP2014123470
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lighting device that facilitates the setting of a light output.SOLUTION: A reed switch 51 turns contacts on under a magnetic force of a magnet and turns the contacts off when the magnet is separated. A magnetic detection circuit 57 outputs a high level signal to a microcomputer 54 when the reed switch 51 turns the contacts on, and outputs a low level signal to the microcomputer 54 when the reed switch 51 turns the contacts off. The microcomputer 54 controls an output circuit 70 to change an LED current value, i.e. a light output, of an LED module 10 on the basis of a sensing result sensed by the magnetic detection circuit 57.
