FIG. 2 is an example of light distribution characteristics when the white LED 100 (V) is used as a light source. The origin O is the position of the white LED as the light source, and the numerical value from 0 ° (360 °) to 350 ° is the value of the white LED as the light source. When the directivity direction is 0 °, each direction, the vertical axis and the horizontal axis are luminance (cd) per 1000 (lm). The luminance at 0 °, which is the directivity direction, is 4517 (cd) per 1000 (lm) at the end point R, and is an arrangement of an elongated substantially elliptical curve having a long axis between the origin O and the point of luminance 4517 (cd). The optical characteristics are shown.

The ceiling 1 serving as a light receiving portion is formed by a curve substantially matching a predetermined curve according to the light distribution characteristics of the LED lamp 5, and the LED lamp 5 is mounted on the mounting portion 4 in a predetermined directional direction. With the ceiling 1 curved and LE
The predetermined curve of the D lamp 5 can be substantially matched. Conversely, the LED lamp 5 having a light distribution characteristic or light distribution area L of a predetermined curve that can substantially match the curved shape of the ceiling 1 serving as the light receiving unit is such that the predetermined curve substantially matches the curved shape of the ceiling 1. It is arranged in.

In the illumination mechanism, the curved shape or the curved shape of the ceiling 1, which is the light receiving portion, and the predetermined curved shape or the predetermined curved shape of the light distribution area L according to the light distribution characteristics of the LED lamp 5 substantially match. Due to the substantially uniform reflection by the entire ceiling 1, it is possible to perform indirect illumination with illumination light having a substantially uniform and substantially uniform luminance distribution, and the position and the like of the light source are not directly visually recognized. It is possible to realize a good indirect illumination which becomes like a soft light source. Therefore, the lighting mechanism enables the lighting to be integrated with the building by integrating the lighting, and the lighting in the building can be harmonized with the space.
