  Since the plurality of small reflection plates 22 are located on the one reflection surface 21 b side of the large reflection plate 21, the light collector 10 reflects the light reflected by the plurality of small reflection plates 22 on the large reflection plate 21. The light can be condensed again on the surface 21b.

  Moreover, the illumination source 100 irradiates illumination light in the display case 110 in all directions. For this reason, a lot of illumination light irradiates in the direction from the back of the display case 110 toward the outlet (buyer) side. On the other hand, since the large reflecting plate 21 is disposed on the outlet side of the plurality of small reflecting plates 22, the irradiation from the back of the display case 110 toward the outlet (buyer) side is efficiently performed, and the plurality of small reflections are performed.
