【Example】

 An embodiment of the flat chandelier device according to the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing the outer appearance of a flat chandelier device according to this embodiment, and FIG. 2 is an explanatory view showing the structure of its light source. As shown in FIG. 1, a flat housing 3 is attached to a ceiling or a side wall of a building through an attachment member 2 of a flat chandelier device 1. The housing 3 has a rectangular shape, and an opening 4 is formed on the surface (the lower surface in FIG. 1) opposite to the surface on which the mounting member 2 is mounted. Since this flat chandelier device 1 is a lighting device having a thin structure with almost no height as shown in the figure, it may be hung on the ceiling of a building with a low ceiling height or mounted along the side wall of a hall or the like. Can be done easily.

Inside the opening 4, a plurality of light sources 5 shown in FIG. 2 are arranged in a matrix. The light source 5 of the present invention has at least one of red (R), green (G) and blue (B) monochromatic light emitters. In the apparatus of this embodiment, one set of the light sources 5 is A tungsten light bulb 6 as a single color light emitter that emits red (R), a tungsten light bulb 7 as a single color light emitter that emits green (G), and a tungsten light bulb 8 as a single color light emitter that emits blue (B). In addition, the three light bulbs 6, 7, and 8 can form any color light. Further, since the light source 5 has a matrix structure, a separating diode 9 1 is connected in series to each of the tungsten bulbs 6, 7 and 8 having only resistance. As the monochromatic light emitting body, a light emitting diode (LED), a xenon lamp, an EL element or the like may be used in addition to the above-mentioned Tungsten light bulbs 6, 7, and 8.

As shown in FIGS. 1 and 2, m (ie, X ₁ , X ₂ , ..., X _m ) in the vertical direction (X-axis direction) and n (ie, in the horizontal direction (Y-axis direction)). , Y ₁ , Y ₂ , ..., Y _n ) of light sources 5 are arranged in matrix in a total of m × n. The light sources 5 arranged in this way have a three-layer structure as shown in FIG. That is, the first layer L ₁ for red light emission, in which m tungsten tungsten bulbs 6 each having a filter for red color are arranged in a matrix in the X-axis direction and n in the Y-axis direction, is arranged on the first-layer substrate. , On the substrate of the second layer, there are m tungsten tungsten light bulbs 7 having a filter for green in the X-axis direction, n in the Y-axis direction, and the green light is arranged in a matrix at the same position as the first layer L _1. On the second layer L ₂ for light emission and on the substrate of the third layer, there are m tungsten bulbs 8 having a blue filter in the X-axis direction, n in the Y-axis direction, and the first layer L ₁ . This is a three-layer structure with a third layer L ₃ for blue light emission arranged in the same position in a matrix. Therefore, the light bulbs 6, 7, and 8 are installed in total for three layers × m × n. However, since one pixel is reproduced by three light bulbs 6, 7, and 8 for colorization, the realistic number of light sources 5 is m × n. Note that, in FIG. 2, only the light source 5 at the positions of X ₁ and Y ₁ is shown, and the other light sources are omitted.

By the way, if the brightness of each of the light bulbs 6, 7, and 8 is at the level 2 ^a , the color reproduction level is 2 ^{a at} maximum. For example, when a = 3, for example, 2 ^a = 2 ³ = 8, and therefore 8 × 8 × 8 = 512 colors can be reproduced, and the apparatus of this embodiment is based on such a drive circuit.

Further, as shown in FIG. 1, a cover glass 10 is attached to the opening 4 of the housing 3 so as to cover each light source 5 and prevent the light source 5 from being directly visible from the outside. . As the cover glass 10 of this embodiment, a cut glass 10 having an uneven surface having a predetermined shape is used, and by this, the color light emitted from the light source 5 is refracted by the cut glass 10 into beautiful color light in multiple directions. I am trying to do it.

FIG. 3 shows a case in which only the required light sources 5a indicated by black circles among the light sources 5 arranged in a matrix are turned on to display a figure including a Christmas tree and snow around the Christmas tree. It is also possible to make the light source 5a in the tree part green and the light source 5a in the snow part white by controlling the brightness of the light bulbs 6, 7, 8 of the lighted light sources 5a.

FIG. 4 is a block diagram showing a control device 20 for controlling the light source 5. The control device 20 controls the light bulbs 6, 7, and 8 as monochromatic light emitters in the light source 5 at a required position so that the light source 5 can emit any color light.

That is, the graphic storage means 21 such as a replaceable magnetic disk or magnetic tape is previously stored with the graphic of a predetermined shape and the dynamic movement of the graphic and light as graphic information. When the signal based on the graphic information stored in the graphic storage means 21 is output to the central processing position (CPU) and the power supply 22, the CPU 22 performs arithmetic processing to emit the light source 5 in which position and in which color. It is determined whether or not to perform, and the X-axis drive unit 23 and the Y-axis drive unit 24 are driven via the power supply 22. The X-axis drive unit 23 sequentially scans the X-axis from the positions X ₁ to X _{m one by one} from the first layer L ₁ to the third layer L ₃ , and during this time, the Y-axis drive unit 24 also scans the Y-axis. The first layer L ₁ to the third layer L ₃ are sequentially scanned one by _one from the positions Y ₁ to Y _n, and a voltage is applied only to the light source 5 at the position to be turned on at this time. As a result, the applied light source 5a at the required position is turned on, and a predetermined figure as shown in FIG. 3 can be displayed as a whole. Further, by changing or exchanging the figure information stored in the figure storage means 21 to other information, it is possible to easily switch to another type of figure, and in addition to the static figure, the dynamic state of the figure and the state of light can be changed. You can also display various movements. Moreover, since the voltage to be applied is variable in N steps, the brightness of each of the light bulbs 6, 7, and 8 can be increased or decreased in stages, and the light of any color can be obtained.

The graphic storage means 21 may be a graphic storage memory built in the CPU 22, and by displaying the layout of the graphic with artistry on the board, the graphic showing the individuality is displayed. You can Also, by changing the pulse width of the electric power output from the power supply with time, it is possible to exhibit the same change in light as in the case of using cut glass.

As described above, in the present embodiment, the light bulbs 6, 7, and 8 to be lit are not connected to all the intersections of the X axis and the Y axis in the ON state in advance, but are stored in the figure storage means 21. The control unit 20 sequentially connects the light bulbs 6, 7 and 8 to the ON state for each layer in order from the first layer L ₁ to the third layer L ₃ according to the previously stored graphic information.

Each light source 5 in this embodiment has a three-layer structure of a layer L ₁ for R, a layer L ₂ for G, and a layer L ₃ for B. It is not necessary to use all of B, and at least one or more of R, G, and B may be provided. Further, it is not always necessary to provide the light sources 5 at all the intersections of the X axis and the Y axis, and the light sources 5 may be arranged only at the required intersections.

Further, if a cut glass is attached to the emission side of the light bulbs 6, 7, and 8 of each light source 5, the brilliance of the emitted light from the light source 5 can be further changed, and a more unique chandelier can be obtained. be able to. In the drawings, the same reference numerals indicate the same or corresponding parts.
