Title: LIGHT-EMITTING SYSTEM
Abstract:
In this invention, a standard direction (S) is defined as the horizontal direction (the direction along the X-direction in the figure). A base material (200) is supported by a frame body (250) in such a manner that a second surface (204) of the base material (200) is oriented obliquely upward from the standard direction (S). This causes a reference direction (R) to become oriented obliquely upward from the standard direction (S). For light from a light-emitting region (242) (more specifically, a light-emitting unit (172)), the light distribution has a higher luminosity in a different direction from the reference direction (R), specifically, for instance, in the standard direction (S), compared to that in the reference direction (R). Therefore, the light distribution has a high luminosity in the standard direction (S), even if the base material (200) is tilted from the standard direction (S).
