PROBLEM TO BE SOLVED: To provide am illumination apparatus and producing method of thereof, in which harmony with the other interior material is realized without increasing the number of parts and light is efficiently obtained from an interior material.SOLUTION: An illumination apparatus 1A comprises a light source 20 emitting light, a light guide plate 10A guiding light and emitting the light from light emitting surface, and an interior material 112 which comprises a plurality of opening parts 112a having a size of a predetermined size as defined as the lower limit size which can be recognized by a human and covers the light emitting surface of the light guide plate 10A. A light controlling part 12A guiding direction of the light to a direction to the opening parts 112a is formed on the light guide plate 10A. The plurality of opening parts 112a of the interior material 112 are formed at a position corresponding to a position where the light controlling part 12A is formed.SELECTED DRAWING: Figure 4
【課題】部品点数を増加させることなく、他の内装材との調和を図り、かつ、内装材から効率よく光を取り出すことができる照明装置およびその製造方法を提供する。【解決手段】照明装置1Aは、光を出力する光源20と、光を導光して光出射面から光を出力させる導光板10Aと、人が認識できる大きさの下限として予め定められた大きさより小さい大きさの複数の開口部112aが設けられ、導光板10Aの光出射面を覆う内装材112とを備え、導光板10Aには、光の方向を開口部112aの方向に導く光制御部12Aが形成され、内装材112の複数の開口部112aは、光制御部12Aが形成された位置に対応した位置に形成されている。【選択図】図4
