Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a light emitting dial plate in which unnecessary portions other than the light emitting portion can be easily cut and deleted, and the cut character portion is all connected to the light emitting portion.

[0002]

[Prior art]

 In the light-emitting display device, the cut characters are used in practical use by sticking cut characters such as transparent vinyl on a milky white or translucent color acrylic plate and projecting lighting such as fluorescent light from the back. I have. In practical cut letters, the light of the fluorescent lighting must be transmitted from the back, and the space between the fluorescent lighting and the cut letters has a margin from the comparative mounting surface. Normally, the distance between the fluorescent tube and the cut characters was set aside for the natural coloring effect of the advertising field of view for uniform light emission from the backside illumination of the character, but it was easy to see because of the fluorescent tube light emitting display device. To do so, it was practically sufficient to add a plurality of fluorescent tubes.

However, when providing an outdoor advertisement or the like, it is necessary to secure a sufficient light source such as a fluorescent tube of a light emitting display device in order to realize a high degree of character recognition from a relatively long distance. In order to secure a sufficient light source such as a fluorescent tube, the area of the housing of the display device becomes large, and the life of the light source such as the fluorescent tube is short due to heat generation of the light source.

[0004] In applications where the display device is used indoors in general, the drawback that the area of the housing becomes large is a major obstacle in selecting an installation location. Specifically, taking unnecessary places, considering heat radiation, struggling with insect control, discoloring due to replacement of equipment due to the life of the light source, or mixing of the color of the rear projection light source and the color of the cut character. There were problems such as.

[0005] As a remedy, there is a method of reducing the size of the housing in the thickness direction by using high-intensity illumination of the sun color for the problem of discoloration or the like. FIG. 2 is an explanatory view showing a mounting mode of high-intensity lighting by this method, and is a cross-sectional view taken on a plane perpendicular to the cut character plane. In FIG. 2, 9 is a letter, 8 is an acrylic case, and 10 is a lighting lamp. However, even with this method, it is necessary to secure a width (11 in FIG. 2) that cannot be ignored because of mounting of high-intensity lighting.

[0006]

[Problems to be solved by the invention]

 The problem to be solved is that the cut character itself cannot emit the required color.

[0007]

[Means for Solving the Problems]

 The main feature of the present invention is that a light emitting diode is connected in parallel to the character surface of a cut character having an arbitrary shape, and the cut character portion emits light even when an unnecessary portion other than the light emitting portion is cut and cut. Alternatively, the thickness of the housing was reduced as much as possible to reduce the weight, and the number of components was reduced to a minimum without compromising the performance of the components.

【Example】

 FIG. 1 is a perspective view of one embodiment of the device of the present invention, wherein 1 is a sectional position of a cut letter, and 6 is an enlarged top view of 1. FIG. Reference numeral 3 denotes a light emitting diode group, and reference numeral 4 denotes a printed circuit board, which has a pair of electrodes sandwiching a ground electrode of a flat electrode and an insulating plate. They are connected.

A plurality of light emitting diodes 5 are connected between the ground electrode of the five flat electrodes and a pair of electrodes with an insulating plate interposed therebetween, and each light emitting diode 5 emits light in parallel. is there. The RGB light emitting diodes can change the color by changing the voltage of three colors, and are connected in parallel on a multilayer printed circuit board.

FIG. 3 is a side view of a component mounting portion when connecting in parallel with a multilayer printed circuit board. FIG. 9 is a simplified side view of the connection between the electrodes 12 to 14 of each color of RGB of the light emitting diode 5 and the common electrode 15.

As described above, the cutout 5 is connected from the printed circuit board 4 to the light emitting dial plate 2, and between the paired electrodes 12 or 13 or 14 is formed as a pair of parallel circuits. No matter what shape it is distributed on the plate, the light emitting diode emits light by being connected via 5, between each 12, 13 or 14 and the paired 15 through 15.

As described above, the light-emitting dial plate of the present invention can eliminate unnecessary portions other than the character portion and the pattern portion, and directly emit light without deteriorating the appearance of the background, thereby achieving high brightness and light weight. It is possible to reduce the thickness to about 5% compared to the conventional thickness, and the heat generation is reduced compared to the conventional one, the service life is remarkably improved, and no countermeasures such as insect control of the conventional eight cases are required. In addition, it is easy to select a mounting location, and the present invention can be applied to use of explosion-proof devices such as ships.
