Definitions

  • the hemispherical reflectance of the semi-specular film 21 is 0.70 to 0.90.
  • the hemispherical reflectance is the ratio of the total luminous flux of reflected light to the total luminous flux of incident light from all directions on the film surface.
  • the light taken into the inside of the duct body 11, that is, into the cavity is normally incident on the surface in the cavity from all directions (all angles), so that the characteristics of the semi-specular film 21 used in the optical duct 10 are hemispherical. It is convenient to characterize by reflectance. This is because the hemispherical reflectance is not affected by the variation in reflectance with the incident angle, and the variation is already taken into account.
  • the first semi-specular film 51 and the second semi-specular film 52 overlapped with each other are used as the optical layer. 14 is attached.
  • both the first and second semi-specular films 51 and 52 have polarization.
  • the lower limit of the hemispherical reflectance of the first and second semi-specular films 51 and 52 may be 0.20, 0.40, or 0.45.
  • the upper limit of the hemispherical reflectance may be 0.55, 0.60, or 0.80.
  • the hemispherical reflectivities of the semi-specular films 51 and 52 may be the same or different.
  • the semi-specular films 51 and 52 are overlapped so that one film forms an angle ⁇ that is greater than 0 degree and less than 90 degrees with respect to the other film.
  • a lighting device 200H shown in FIG. 24 is a modification of the lighting device 200F shown in FIG.
  • the illumination device 200H differs from the illumination device 200F in that the wire 240 is omitted and the bar-type illumination 220 is attached only by the fixture 252. Also in this lighting device 200H, the inside of the fixture 252 to which the bar-type lighting 220 is attached is isolated from the space in the duct body 111 through which natural light passes. A reflective material is affixed to the inner wall separating the interior.
  • Example 1-2 In the same manner as in Example 1-1, a duct body was produced and windows 1 to 3 were formed. The difference from Example 1-1 is that an additional diffusion plate (EX432) is attached to the diffusion sheet side of the multilayer optical film manufactured by 3M in the window 1. Therefore, the window 1 uses two diffusion plates. The optical layers in the windows 2 and 3 were the same as those in Example 1-1.
  • EX432 additional diffusion plate
