Description

[Detailed description of the device]

[0001]

[Industrial application]

 It relates to the structure of an edge light type display device using a light source used for displays and the like.

[0002]

[Prior Art]

 FIG. 4A is a vertical cross-sectional view of a conventional edge light type display device a. In FIG. 4 (A), a transparent plate c made of glass or acrylic having a display mark b subjected to so-called spreading treatment such as satin finish, etching or local recess treatment on the back surface is adjacent to one end face. A light source d is provided, a C-channel reflector e1 including the one end face c1 and the light source d is provided, and a C-channel reflector e2 is similarly provided on the other three end faces. It is set up.

Since the conventional example is configured as described above, when the power source of the light source d is turned on during use and the light source d emits light, the light beam d1 is transmitted from the end face c1 of the transparent plate c to the transparent plate c. The incident light d1 'is scattered into the outer periphery in the diffusion process of the display mark b. Therefore, as shown in FIG. 4 (B), when viewed from the surface opposite to the rear surface of the transparent plate c on which the display mark b is formed, whether only the display mark b emits light due to the scattered light of the display mark b. You can see it like.

As described above, in the conventional example, since the light source d is of a single color, the display mark is only visible in a single color, and there is no stereoscopic effect. Whether the display mark is turned on or off by turning the light source on or off. There was a drawback that only monotonous display could be done.

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and an object of the present invention is to provide an edge light type three-dimensional display device using a multi-color LED light source in which display marks can be visually recognized in three colors in three colors.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an edge light that diffuses a display mark on the back surface of a transparent plate and introduces light from the end surface of the transparent plate to project the display mark in the color of the light. In the display device, the display marks are diffused on the back surfaces of the plurality of laminated transparent plates, and light of different colors is introduced from the respective end faces of the plurality of transparent plates to display the respective display marks. We have adopted a configuration that projects in different light colors.

[0007]

[Action]

 The display marks are diffused on the back surfaces of the plurality of laminated transparent plates, and light of different colors is introduced from the respective end faces of the plurality of transparent plates. Is projected in the color of.

[0008]

【Example】

 FIG. 1A is a vertical sectional view of an edge light type three-dimensional display device A using a multicolor LED light source of an embodiment according to the present invention, and FIG. 1B is a front view of the same. In FIG. 1 (A), a transparent plate 11 made of glass or acrylic with a display mark 21 on the back surface, which has been subjected to so-called diffusion treatment such as satin treatment, etching or local recess treatment, and the same diffusion treatment. A transparent plate 12 made of glass or acrylic with the display mark 22 formed on the back side and a transparent plate 13 made of glass or acrylic with the display mark 23 also subjected to the diffusion treatment on the back side are laminated in the same direction. ing.

A plurality of light sources (for example, red LEDs) 31 mounted on the substrate 5 are provided adjacent to one end face 11 ′ of the transparent plate 11, and also adjacent to one end face 12 ′ of the transparent plate 12 similarly. A plurality of light sources (eg, green LEDs) 32 mounted on the substrate 5 are provided, and a plurality of light sources (eg, orange LEDs) mounted on the substrate 5 are also adjacent to one end face 13 ′ of the transparent plate 13. 33 is provided.

An end face 11 ′ of the transparent plate 11, an end face 12 ′ of the transparent plate 12 and an end face 13 ′ of the transparent plate 13 and the respective light sources 31, 32 and 33 are provided with a C-channel type reflection plate 4. In addition, reflective partitions 41, 42 are provided between the light sources 31, 32, and 33, and a reflective film is also attached to the upper surface of the substrate 5. In the space S below the substrate 5, electric wires are connected to the legs of the light sources 31, 32, and 33, and switch means (not shown) for the respective groups of light sources 31 ', 32', and 33 'are installed. Has been done.

A C-channel-shaped reflection plate 41 is also arranged on the end faces of the other three transparent plates 12, 12, and 13. Since the embodiment according to the present invention is configured as described above, when the switch of the group of light sources 33 'is turned on at the time of use, the group of light sources 33' emits orange light, and the orange light beam is transparent plate 13. Is introduced into the transparent plate 13 from its end face 13 '. As is well known, the orange ray that once entered the transparent plate 13 repeats total reflection on the surface, so that it does not re-enter the other adjacent transparent plate 12 and does not diverge to the opposite air side. The display mark 23 formed on the back surface of the transparent plate 13 is diffused and visible from the D direction.

That is, in this case, the display mark 23 emits orange light as the sunset sky (see FIG. 3). Then, when the switch of the group of light sources 32 'is turned on, the group of light sources 33' emits green light, and the green light beam is introduced from the end face 12 'of the transparent plate 12 into the transparent plate 12'. As is well known, the green ray that once enters the transparent plate 12 repeats total reflection on the surface, so that it does not re-enter the other adjacent transparent plates 11 and 13 and the transparent plate does not re-enter. The display mark 22 formed on the back surface of 12 is diffused only when it is diffused and visible through the transparent plate 13 from the D direction.

That is, in this case, the trees and the lawn of the display mark 22 emit green light (see FIG. 2B). Then, when the switch of the group of light sources 31 'is turned on, the group of light sources 31' emits red light, and the red light ray is introduced from the end face 11 'of the transparent plate 11 into the transparent plate 11'. As is well known, the red light ray that once enters the transparent plate 11 repeats total reflection on the front surface, so that it does not re-enter the other transparent plate 12 adjacent to it and the air side of the back surface. The display mark 21 formed on the back surface of 11 is diffused only when it is diffused and visible through the transparent plates 12 and 13 from the D direction.

That is, in this case, the butterfly flapping the display mark 21 emits red light (see FIG. 2A). That is, when this state is viewed from the direction D in FIG. 1 (A), as shown in FIG. 1 (B), the butterfly with the flapping display mark 21 emits red light, and the trees and lawn with the display mark 22 grow. In addition to emitting green light, the display mark 23 emits orange light as the sunset sky, and the whole view can be seen in multicolor in a very stereoscopic manner. In this case, when it is desired to emphasize the flapping butterfly, the display mark 21 may be blinked by blinking means.
