Abstract
A standard direction (S) is a horizontal direction (a direction along X direction in the drawing). A base material () is supported by a frame body () so that a second surface () of the base material () is oriented obliquely upward from the standard direction (S). Thereby, a reference direction (R) is oriented obliquely upward from the standard direction (S). Light from the light-emitting system () has standard chromaticity in the standard direction (S). In addition, the light from the light-emitting system () has first chromaticity and second chromaticity in a first side direction (S) and a second side direction (S), respectively, the first side direction (S) and the second side direction (S) being symmetric with respect to the standard direction (S). A difference between the first chromaticity and the standard chromaticity is smaller than a difference between the second chromaticity and the standard chromaticity.
