PROBLEM TO BE SOLVED: To provide a reflection plate array and a light-irradiation device capable of, when arranging a plurality of light-emitting diodes to emit light, effectively collecting the light emitted from each of the light-emitting diodes.SOLUTION: A reflection plate array of the present invention is attached to a light irradiation device that comprises: a substrate; and a plurality of light-emitting diode units each having at least one light-emitting diode element provided on one surface of the substrate. The reflection plate array comprises a plurality of reflection units which are arranged to rise from the substrate and which surround the light-emitting diode units, respectively, to form an irradiation space. Each of the reflection units comprises a plurality of reflection surfaces which surround each of the light-emitting diode units. |
