FIG. 4 shows the luminance distribution characteristics of the ceiling surface 2 obtained by the experiment, and the numbers 1 to 5 are the luminance (C
d / m 2 ). In this way, the peripheral portion 2 of the ceiling surface 2
By providing the illumination lamps 4 on a, b, 2c, 2d and making the peripheral portions 2a, 2b, 2c, 2d brighter than the central portion 2e of the ceiling surface 2, the ceiling surface 2 can be widely perceived. .. The reason for this is as follows. That is, it is known that, in a general indoor living space, it is possible to perceive the living space more widely by making the peripheral part brighter than the central part rather than making the central part brighter than the peripheral part (Illumination Society of Japan). Volume: Writing Handbook P.267 Figure 11 ・
32 and P.431 (see Figures 19 and 12), the passenger compartment is often smaller than a typical indoor living space, but in this case as well, applying the above idea will produce a similar effect, that is, a spread. It is perceptible. Furthermore, since the ceiling surface 2 emits diffused light almost uniformly and illuminates the interior of the vehicle softly,
You can feel secure and relaxed.
