- each LED 19 It is possible to arrange the illumination cover 17 close to each LED 19 by disposing a lens between each LED 19 and the illumination cover 17 to widen the diffusion angle of light from the LED. There is a limit to the improvement in design because light spots are generated or the illuminance is lowered due to the influence of diffraction or the like.
- each LED 19 has a directivity characteristic in which the relative luminous intensity is 80% or more in an area where the angle with respect to the optical axis is 20 degrees or less, and the pitch X (mm) between the LEDs 19 is Since the relationship with the distance Y (mm) between each LED 19 and the illumination cover 17 is a relationship satisfying Y ⁇ 0.9X + 9, it is possible to avoid overlapping ranges of high light intensity for the LEDs 19 adjacent to each other, The luminous intensity at the position of the illumination cover 17 can be made close to each other. Therefore, it is possible to suppress the occurrence of light and darkness in the illumination cover 17, and it is possible to approach a design that gives a soft impression as if the entire illumination cover 17 shines evenly. Thereby, the design property of the illuminating device 8 can be improved. Moreover, since the directivity of each LED 19 is set within the range of directivity of a general LED, the cost of each LED 19 can be reduced.
