INDOOR AUXILIARY LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide an indoor auxiliary luminaire which obtains a high brightness within a room space with fewer watts, that is, while saving energy. SOLUTION: A side from a main luminaire which lights the whole room inside a house having a wall 1 with low reflectivity, an indoor auxiliary luminaire is arranged on the above-described wall inside the room. The auxiliary luminaire has a light emitting surface which lights up with a luminance L (dc/m2) within a range of 0.8×Emax/π<=L<=Emax/π, in view of Emax (1x) which is a maximum iluminance value at respective points of a wall surface of the wall 1 irradiated with a light emitted from the main luminaire and the auxiliary luminaire.
