Title:
LUMINAIRE
Document Type and Number:
Japanese Patent JP2016219389
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a luminaire capable of securing necessary light emitting characteristics while reducing a load of a battery at emergency light emission, without complicating a structure for normal light emission.SOLUTION: A luminaire 10A includes: a power feeding part 11 to which power is supplied from an external commercial power supply 20; a battery 15; a power outage detection part 14 for detecting power outage of the commercial power supply 20; a light emitting part 13A including an LED module 131, and an LED module 132 whose luminous efficiency is higher than that of the LED module 131; and a lighting control part 12A for, in the case where the power outage detection part 14 does not detect power outage, allowing at least the LED module 131 to emit light by power supply from the power feeding part 11, and in the case where the power outage detection part 14 has detected power outage, allowing the LED module 131 to extinguish light, and also allowing the LED module 132 to emit light by power supply from the battery 15.SELECTED DRAWING: Figure 2
