发明名称 LIGHTING APPARATUS AND INDIRECT LIGHT UNIT
摘要 PROBLEM TO BE SOLVED: To provide a lighting apparatus capable of suppressing illuminance irregularity on a ceiling in a peripheral direction when indirect light units irradiate the ceiling with light.SOLUTION: A lighting apparatus 1 is configured so that four long indirect light units 30 are arranged into a square in a plan view to emit light toward an outside of the square. Each indirect light unit 30 includes: a long mounting substrate 32; a first light source 33a1 installed in a central region 32a1 in a case of dividing the mounting substrate 32 into three regions in a longitudinal direction; and a second light source 33a2 installed in each of both side regions 32a2 and 32a3. A luminous flux of the light emitted from each second light source 33a2 is larger than that of the light emitted from the first light source 33a1.
