| description | To provide a luminaire which is constituted so as to be able to emit two or more light beams having light distribution different from each other.SOLUTION: A luminaire 100A has a first light source LS1 and a first light guide member 10A1. The first light guide member 10A1 has: a first illumination member 110A1 having a first light guide layer 10A1, and a first light distribution control structure capable of directing a part of first light propagating in the first light guide layer at least to the front surface side; a second light source LS2; and a second light guide member 10A2 arranged on the front surface side of the first light guide member. The second light guide member has: a second illumination member 110A2 having a second light guide layer 10A2, and a second light distribution control structure capable of directing a part of second light propagating in the second light guide layer at least to the front surface side; and a low refractive index layer 20 arranged between the first light guide member and the second light guide member, and having a refractive index lower than any of the first light guide layer and the second light guide layer.SELECTED DRAWING: Figure 1A
