  • Downlights 10 are disposed in a vicinity of four corners of the lighting box 4.
  • the LEDs 7 are arranged into a matrix.
  • the cage lighting apparatus according to Embodiment 1 includes the lighting box 4, the light source portion 5, the ceiling grid 8, and the prism-cut lighting plates 9.
  • Figure 8 is an explanatory diagram that schematically shows a pattern of transmission and refraction of light that is formed by a prism-cut lighting plate 9 from Figure 2 .
  • Light that is emitted from a single LED 7 is refracted in various directions and diffused by the indentations and protrusions of the prism-cut lighting plates 9.
  • the light from the LEDs 7 can be captured visually only in a region that corresponds to a light distribution angle of the LEDs 7, making the visible region constant irrespective of the presence or absence of the lighting plate. If a smooth lighting plate is used, then there is also no change in the appearance of the light according to viewing angle.
  • the light from the LEDs 7 that does not enter the visual angle in the smooth lighting plate can be visually captured when the prism-cut lighting plates 9 is used because the light is then refracted and diffused by the prism-cut portions. Consequently, play of light that corresponds to the cut shape is made possible, and changes in the three-dimensional appearance (the shape) of the light can also be brought about using the viewing angle.
  • a cage lighting apparatus of this kind because the light source portion 5 that uses the LEDs 7 and the prism-cut lighting plates 9 on which the prismatic indentations and protrusions are formed at a pitch that is smaller than the disposed pitch of the LEDs 7 are combined, the light from the LEDs 7 is visible through the prism-cut lighting plates 9 from inside the cage 1, and lighting design can be easily modified by altering the shape of the indentations and projections of the prism-cut lighting plates 9, enabling lighting design freedom to be improved and also enabling decorative design to be improved using a simple configuration.
  • Figure 9 is a cross section of a cage lighting apparatus according to Embodiment 2 of the present invention.
  • a plurality of special coated lighting plates 11 that transmit light from LEDs 7 are disposed between a light source portion 5 and prism-cut lighting plates 9.

  • a special coating in which the color of the transmitted light changes to rainbow colors (seven colors) depending on the viewing direction is applied to each of the special coated lighting plates 11.
  • the special coated lighting plates 11 diffuse and emit incident light depending on wavelength.
  • PLEXIGLAS RADIANT product name that is manufactured by Evonik Degussa GmbH (Germany) can be used as special coated lighting plates 11 of this kind, for example.
  • the rest of the configuration is similar or identical to that of Embodiment 1.
  • Lighting design can be easily modified by changing shapes, sizes, and positions of the special coated lighting plates 11, enabling lighting design freedom to be improved and enabling decorative design to be further improved using a simple configuration.
  • the special coated lighting plates 11 were disposed partially, but may also be disposed so as to face the entire light source portion 5.
  • the special coated lighting plates 11 were disposed between the light source portion 5 and the prism-cut lighting plates 9, but the position of the prism-cut lighting plates 9 and the position of the special coated lighting plates 11 may also be interchanged.
  • the prism-cut lighting plates 9 may be disposed so as to face the entire light source portion 5 even if disposed partially.
  • the prism-cut lighting plates 9 may also be omitted, also enabling the decorative design to be improved by only the special coated lighting plates 11.
  • Embodiments 1 and 2 a certain amount of spacing was disposed between the LEDs 7 and the prism-cut lighting plates 9, but the LEDs 7 may also be placed in close proximity to the prism-cut lighting plates 9. Furthermore, various modifications to the shape, number, and size of the indentations and protrusions that are formed on the prism-cut lighting plates 9 are possible, and the pitch of the indentations and protrusions of the prism-cut lighting plates 9 may also be made equal to the disposed pitch of the point light sources. In Embodiments 1 and 2, only a single layer of prism-cut lighting plates 9 were disposed between the light source portion 5 and an interior portion of the cage 1, but a plurality of layers may also be disposed so as to be stacked. In that case, different types of prism-cut lighting plates 9 may be stacked, or similar or identical types of prism-cut lighting plates 9 may be stacked. The prism-cut lighting plates 9 may also be stacked so as to leave spacing therebetween, or without leaving spacing.
  • prism-cut lighting plates 9 are not limited to those in Embodiments 1 and 2. Different types of prism-cut lighting plates 9 may be disposed side by side in a common plane.
  • the appearance of the lighting design changed depending on the position of the passenger inside the cage 1, but the appearance of the lighting design may also be changed actively by moving at least one of the light source portion 5, a prism-cut lighting plate 9, or a special coated lighting plate 11, by a driving means such as a motor, etc.
  • driving methods of this kind include methods such as changing the angle of inclination of a prism-cut lighting plate 9 or a special coated lighting plate 11, or rotating a prism-cut lighting plate 9 in a horizontal plane, for example.
  • prism-cut lighting plates 9 and special coated lighting plates 11 can also be used for local lighting apparatuses such as the downlights 10 that are shown in Figure 5 , or spotlights, for example. If applied to a spotlight, for example, a plurality of point light sources should be disposed inside a dome-shaped reflecting plate so as to be spaced apart from each other, and at least one prism-cut lighting plate 9 or special coated lighting plate 11 disposed therebelow. In such a construction, a pattern of light can be generated on a floor surface and wall surfaces inside the cage 1 that face the lighting apparatus, enabling decorative design to be improved throughout the cage 1.
  • LEDs 7 were used as the point light sources, but the point light sources are not limited to LEDs 7, and may also be lensed incandescent lamps, for example.
  • the light-emitting shape of the point light sources is also not limited to a conventional circular shape, and may also be ring-shaped (donut-shapes), quadrangular, or triangular, for example.
  • a cage lighting apparatus according to the present invention was disposed on the ceiling 3, but the position of installation is not limited to the ceiling 3, and may be installed on the cage wall 2 or a car floor, for example.
