• a lighting device being used much for an advertizing board is very simply constructed.
• an advertizing board using optical fibers which is capable of delicate change of various colors is also used, but not only arrangement of numerous optical fibers is required but also manuf cturing time is required much and excessive expense is required, and since it is made to exhibit the figure by dot, it is difficult to arrange the optical fibers so as to have continuity of the figures, and thereby it has disadvantage that it is impossible to use for a large advertizing board.
• Another object of the present invention is to provide a light exhibiting device which is very simple and compact in internal and external structure of advertizing board and having clear color and excellent in sense of beauty.
• the present invention comprises, in order to achieve above-described objects, piled members formed by piling a plurality of transparent plastic plates of board shape; light reflecting portions formed by engraving letters or figures on rear portion of the transparent plastic plate; coating layers formed by coating polymer material being big in refraction rate than the plastic plate on to surface of the plastic plate; colored portions which are selectively applied with paint passing through only particularly colored light ⁇ to all directions of side surface of each plastic plate forming the piled members; supporting frames for fixing by receiving the piled members; a plurality of partitioning walls integrally formed to the supporting frame which are interposed between the supporting frame and the piled members so that each independent chamber is partitioned; illuminating lamps which are provided by at least one at each chamber partitioned by the partitioning walls, and that a portion confronting to side surface of the piJed member includes a condensing lens; and an illumination control device for controlling a brightness and lighting-on order of the illuminating lamps provided in each chamber; so that advertizing effect is obtained by making the letters or figures to be changed

• FIG.l shows a cross sectional view of the present. invention, and a transparent plastic plate 1 having - ⁇ - thin and wide area, for example, a plurality of plastic plates 1 formed with acryl resin plate which is cheap and capable of easily obtaining are piled so as to form a piled member doing a role of advertizing board or ornamental picture frame.
• the letters or figures as a desired advertizing draft are engraved on rear surface, that is, bottom surface by a reversed shape so as to form a light reflecting portion 3 which makes to reflect when the engraved boundary surface receives a light.
• a coated layer 4 is formed in which polymeric material than the plastic plate, for example, silicon is applied in thin on at least one side surface of the plastic plate 1. Since the coated layer 4 is polymeric material, a refraction rate of light is high, and since a reflection property of light becoming to reflect a light incident more than a predetermined angle is high, when a light is radiated from a hereinafter described illuminating lamp 5, it becomes to do a role as an isolating film for isolating a leakage of light to a neighboring plastic plate so that the light is concentrated to the light reflecting portion 3 so as to have further more clear color.
• polymeric material than the plastic plate for example, silicon is applied in thin on at least one side surface of the plastic plate 1. Since the coated layer 4 is polymeric material, a refraction rate of light is high, and since a reflection property of light becoming to reflect a light incident more than a predetermined angle is high, when a light is radiated from a hereinafter described illuminating lamp 5, it becomes to do
• a reference numeral symbol 6 is a supporting frame for fixing by receiving the piled members 2, and a plurality of partitioning walls 7 are integrally formed and an end portion of the partitioning wall 7 is contacted to a side portion of the piled member 2 so that independent chambers 8 partitioned by the partitioning wall 7 are included.
• One or a plurality of illuminating lamp s) 5 are positioned at each chamber 8.

• Light transmissive paint of one color of various colors for example, red R), green(G), yellow(Y), blue(B) is colored at around of side surface of the plastic plate 1 confronting to each chamber 8 formed by the plurality of partitioning walls 7, or colored portion 30 attached with separate colored plate having a such color is formed, and colored portion 10 determines a passing color of light to be radiated to interior of the plastic plate 1.
• FIG.2 shows a cross sectional view the plastic - y - plate 1 engraved with advertising draft, which is a diagram showing that the plastic plate 1 is cut out to a mountain shape, bent surface shape, low wave shape whereby forming a reflecting portion 3, and since reflecting degree of light becomes different in response to the engraved shape, atmosphere can be differently produced by little in accordance with engraved shape, and generally mountain shape ( type. is used much, and in case of cutting out to the mountain shape ( ⁇ type), an inclined angle of the boundary surface is desirable at about 15 - 45 degrees, and at this moment, since the cut out inclined surface is semi-transparent state, the light becomes reflected to forward direction.
• FIG.3 shows a diagram of area influenced with light radiated from the illuminating lamps, and since respective illuminating lamps 5 send light, only to forward direction, only one portion of the plastic plate 1 is shined , but since a plurality of lamps are arranged around all directions of the plate, dead angle area of the light is not produced.
