Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of an electric sign with an LED projection type, and more particularly to an electric sign which uses an LED as a projection light source, is easy to assemble as a whole, has a light appearance, is beautiful, and is easy to install.

[0002]

[Prior art]

 Most of the indicator lights, recognition plates, and signboards commonly used in public places such as airfields, stations, hospitals, department stores, and offices use electric lights as their illuminating light source, and illuminate from inside to outside. The letters or designs on the translucent plate shall be prominent and serve the purpose of indicating or recognizing them. Such conventional indicator lamps and small signboards take up space for electric lights and also require electronic components such as ballasts. It is conspicuous and impairs the overall aesthetics, but sometimes has drawbacks such as obstruction of traffic.

[0003] Further, since the conventional electric lamp has only one color, the indicator lamp and the small signboard can be displayed only in a single color. For example, if the white color used by the light and the color of the surrounding lighting are similar, the purpose of clarifying instructions and identification will be impaired, so it is important to make the display clearer, especially in an emergency.

[0004]

[Problems to be solved by the invention]

 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a structure of a light-weight, thin, and easy-to-assemble LED-projection-type electric signboard, which overcomes the above-mentioned disadvantages of the conventional indicator lamp.

[0005]

[Means for Solving the Problems]

 According to the LED projection type electric signboard of claim 1 of the present invention for achieving the above-mentioned object, the signboard comprises a pipe, a transparent light-transmitting plate, and an LED circuit plate. It has a function that can be installed freely, such as a ceiling, a wall, or a flat surface, according to different places and heights. Since the present invention can express different colors on the translucent plate, it has a convenient function for color change and identification.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, as shown in FIGS. 1 to 5, the present embodiment includes the following. A pipe 1 formed of a material such as metal or plastic is provided. An opening below the pipe 1 extends downward, and two installation plates 11 are installed. One or more outwardly opening slide tanks 12 are provided around the pipes. The slide tank 12 has a narrow opening, and the bottom of the tank has a C-shape or T-shape. A mounting tank 13 extending in the axial direction is formed in the pipe, and one LED circuit plate 2 is installed in the mounting tank 13. The LED circuit plate 2 is installed in the slide tank 13 of the pipe 1, and the LED lamps 21 are installed side by side. Necessary characters or designs 31 are engraved on the plate surface of the translucent plate 3, and are fixed to the two installation plates 11 of the pipe 1 at the upper end of the mounting portion 32. The slide portion 41 at the lower end of the localization unit 4 is fitted into the slide tank 12 of the pipe 1, and a hook hole 42 for hooking is provided at the upper end of the localization unit 4.

The cover 5 is fixed to both sides of the pipe 1 by a lock unit 51 or an adhesive method, and fixes the LED circuit plate 2, the light transmitting plate 3, and the localization unit 4 in a localization manner. On both sides and the bottom end of the light transmitting plate 3, an opaque edge frame 33 or reflected light paper is additionally provided to prevent irregular reflection of light and enhance the display effect of the light transmitting plate 3. . When the function required for the light-transmitting plate 3 is only one side, as shown in FIG. 4, a colored and light-impermeable back plate 34 is installed behind the surface of the light-transmitting plate 3. In addition, the beautification of the display surface and the degree of projection can be enhanced, and a color that matches the interior of the room to be arranged can be used.

In addition, the above-mentioned pipe 1 can be made into a circular body or into a rectangular shape as shown in FIG. The power supply line 22 of the LED circuit plate is connected to a power supply via one of the holes 52 of the cover 5. For the light transmitting plate 3, any light transmitting material having the same effect can be used, but it is recommended to be made of a transparent acrylic material.

If the height of the translucent plate 3 is too small, no indication or discrimination effect can be obtained. If the height of the translucent plate 3 is larger than 20 cm, the projection brightness of the LED bulb 21 is reduced and the lower part becomes dark. . Therefore, it is considered that about 15 cm is appropriate. For this, a height of about 15 to 20 cm may be selected according to the actual use situation. Since there is no restriction on the length, it can be used at an appropriate length as needed.

[0010] With such a configuration, processing and manufacturing of the present invention and installation on site are very simple. First, as shown in FIGS. 1 and 2, when processing into the present invention, the lengths of the pipe 1 and the light transmitting plate 3 are determined as necessary. The LED circuit plate 2 can be selected according to a variety of length standards, and each LED bulb 21 is designed and arranged in a different color to provide a rich color effect. Can be increased.

As shown in FIG. 3, when each LED bulb 21 is illuminated, the light extends downward along the translucent plate 3 and becomes one bright plate that emits light from the translucent plate 3. Thus, the concavely engraved character or pattern 31 on the translucent plate 3 receives the light and shines three-dimensionally bright, is very conspicuous and beautiful, and the effect of its identification and instruction is enhanced. In addition to the localization function, the two parallel installation plates 11 below the pipe 1 also have the role of preventing the light of the LED bulb 21 from diffusing and projecting the light downward properly.

The present invention is also very convenient for installation. As shown in FIG. 3, the slide portion 41 of the localization unit 4 engages with the slide tank 12 of the pipe 1, and is positioned below the ceiling or on the wall surface by the hook hole 42 at the upper end. The direction of the pipe 1 can be adjusted by the axis below the stereotactic unit 4. This localization unit 4A can of course also take the form as shown in FIG. 7, and the information and the front and rear are all combined with each slide tank 12 of the pipe 1, the extension body 40 is installed, and the slide unit 41 is engaged. You can also.

FIG. 8 shows another embodiment of the present invention, in which the localization unit 4B is in a stationary form. Since the pipe 1 and the light-transmitting plate 3 are engaged with each other in an upward fixed position and are placed vertically, the LED-projection-type electric signboard can be placed on a flat surface, and can be used as a decorative article, a bulletin board, a notice board, or the like. It is designed to be used for various purposes.

Since the structure of the present invention is very sophisticated, it is possible to make the structure of the LED projection type electric signboard lightweight and convenient to install. Further, by projecting various kinds of light rays of the LED bulb 21 onto the translucent plate 3, not only the entire plate surface is enhanced, the degree of discrimination is improved, but also the texture of the entire indoor and outdoor space is improved. is there. In addition, due to the ingenious shape of the pipe, various different localization units are combined to have various functions such as various warning slogans at the time of process construction and other notices.
