The present invention relates to a light emitting device.

Advertisement devices that are used a lot to display their trade name in the conventional branch is very simple configuration.

That is, it was common to bend the neon tube to form a letter shape that you want to advertise, and then install a lighting device inside and outside the billboard to irradiate light to expose the letter lamp.

However, in the case of advertising board using neon tube, it is impossible to express small letters or detailed figures by bending the neon tube, and in the case of large size, it is impossible to form a single letter or figure entirely. While only advertising effects can be expected, the energy consumption is high, and the gas used in neon devices causes environmental problems, and lighting devices need to be disposed behind the billboards, which makes it difficult to spread the light evenly throughout the billboards. .

In order to solve such drawbacks, billboards have been recently used to obtain various advertisement effects by arranging light emitting diodes to control light emission of the light emitting diodes. However, this requires a lot of installation time and cost for arranging and releasing numerous light emitting diodes. In other words, if some diodes are disconnected, they are often not repaired immediately.

In addition, recently, an advertising apparatus using a liquid crystal display panel has been in the spotlight, but there is a problem that it is not suitable as an advertising apparatus for displaying a magnetic light easily and cheaply in a general store because the installation cost is too expensive.

For this reason, the present inventor has proposed a new way of advertising devices through the Korean Patent Registration No. 114920 and the Patent Registration No. 259013.

The above-mentioned patents are engraved by engraving engraved specific characters or figures on a plurality of transparent plastic plates, and the light emitted from the light source installed on the side of the plurality of stacked plates hits the carved portion and the light is irradiated forward. It is possible to produce letters and figures with various colors at a low cost by forming colored parts that pass only light of a specific color on the side of each board as the letters or letters are exposed. Therefore, it is evaluated to overcome the limitations of the conventional neon-based advertising device.

However, although the above-described prior inventions are still effective, expensive computer manipulators are required for dividing and manipulating complex figures on individual boards, and are too difficult to program and carve to reflect all designs of various figures desired by customers. As it is difficult, there is a limit to relying on a few designs that are popularly developed for the representation of figures, and it is economical in terms of the cheap advertising device that small stores want because the cost of computer fragments is large to satisfy the requirements of customers. This had to fall.

Accordingly, the present invention has been proposed in view of the above, and its object is to be very compact, with a small volume, and a light display device capable of displaying the figures and characters of a desired shape through the front at a uniform brightness while minimizing power consumption. To provide.

In order to achieve the above object, the present invention provides a transparent plastic plate of at least one, a plurality of light reflecting grooves formed in a state that is dug parallel to each other on one side or both sides of the transparent plastic plate, and the transparent plastic plate In the light-emitting device comprising a light source installed on the side to irradiate light through the side of the transparent plastic plate,
The plurality of light reflecting grooves are gradually deeper as they move away from the light source, starting from a portion adjacent to the light source, and each of the light reflecting grooves is formed along a traveling direction of light emitted from the light source.
In addition, the transparent plastic plate is composed of a plurality of stacked on each other, the light reflecting grooves of each transparent plastic plate are stacked in an alternating state to cross each other, the length of the respective light reflecting grooves on the side of each transparent plastic plate The light source is installed so as to irradiate light along the direction.

1, the present invention, the light display device 1 is provided with at least one transparent plastic plate, a plurality of light reflecting grooves (3) at regular intervals on the front surface of the rear transparent plastic plate (2) for reflecting light ) Side by side are formed in a straight line, the light reflecting groove (3) is formed by digging into grooves of a triangular cross section or a quadrilateral cross section, far from the light source (6) installed on the side of the rear transparent plastic plate (2) The deeper it gets, the deeper it is dug.

Accordingly, the light reflecting groove 3 has a light source 6 as shown in FIGS. 3 to 6 when the rear transparent plastic plates 2 are installed on only one side (FIG. 5), toward the opposite side of the rear transparent plastic plate. When the light source 6 is installed on both sides of the rear transparent plastic plates 2, the inclined θ is formed to be processed into a concave shape in the center, as shown in FIG. 6. Is installed so that the light flows in the longitudinal direction along the light reflecting groove (3) to reduce the resistance loss of the light and to increase the efficiency of reflecting light over the entire area of the rear transparent plastic plate (2). And the light reflecting groove (3) is shown largely easy to understand with the naked eye on the drawing, but in order to increase the reflection efficiency of the light it is more preferable to reduce the gap between the light reflecting grooves.

In addition, the front transparent plastic plate 4 is laminated on the front of the rear transparent plastic plate 2 as shown in FIG. 7, and the front transparent plastic plate 4 also has the same shape as the light reflecting recess 3 in front. The light reflecting grooves 3a are formed, and the front and rear light reflecting grooves 3 and 3a are preferably formed so as not to overlap each other in a staggered position, that is, zigzag, and different from each other as shown in FIGS. 7 and 8. The light reflecting grooves 3 and 3a may be disposed in a shape.

And although the light reflecting grooves 3, 3a formed on the rear and front transparent plastic plates 2 and 4 can be formed in one direction parallel to each other, the light reflecting grooves 3 as shown in FIGS. 9 and 10. The rear and front transparent plastic plates 2 and 4 may be laminated so that the 3a crosses each other, and in this case, the light sources 6 and 6a are also installed at right angles or on all four surfaces, respectively. The light irradiated through each of the rear and front transparent plastic plates 2 and 4 passes perpendicular to each other (see FIG. 10).

Although the example of the case where the rear and front transparent plastic plates 2 and 4 are stacked and used is described above, one or three transparent plastic plates having the same shape may be used as necessary.

On the front of the front transparent plastic plate 4 is attached an advertising film 7 printed with the figures or characters selected by the consumer who wants to advertise, and the advertising film 7 is again made of the transparent film protective plastic plate 5 It is protected by lamination.

The transparent film protective plastic plate 5 is used in a plurality of one to three pieces, the surface of the film protective plastic plate 5 by the present inventors to decorate the design that is projected from the advertising film (7) As shown in the prior patent registered techniques (referred to in the prior art), it is possible to form engraved engraved shapes along the contour of the decorative figure 8, and on the side of these film protective plastic plates 5 It is possible to selectively attach the colored film 9 that transmits only the light.

In addition, the rear surface of the rear transparent plastic plate 2 reflects white light in order to prevent loss due to external leakage of light and to reflect the light emitted from the sides of the rear and front transparent plastic plates 2 and 4 to the front. The film 10 and the silver light reflecting film 11 are laminated | stacked in duplicate.

In addition, the light sources 6 are installed inside the frame 12 which surrounds and protects the edges of the laminated front and rear transparent plastic plates 4 and 2 and the film protection plastic plates 5, and the light reflecting grooves 3 are provided. According to the processing form and direction of (3a), the light source 6 has two sides or four sides of which the rear and front transparent plastic plates 2 and 4 form one side, both sides or right angles of the film protective plastic plate 5. Will be installed on all.

When the light emitting device 1 is connected to a power source, the present invention provides the rear and front transparent plastic plates 2 and 4 to the inside of the frame 12 and the film protective plastic plates 5 and the side surfaces of the advertising films 7. The light source 6 provided, one fluorescent lamp corresponding to the length of the plate or a plurality of light source arrangements, emits light and emits light.

The light irradiated from the light source 6 travels inside the body along the body of the transparent rear and front transparent plastic plates 2, 4, ie along the longitudinal direction of the light reflecting grooves 3, 3a, and on the opposite side. When the light reaches the cut portion of the light reflecting groove (3) (3a), the light is reflected as shown in Figs. 5 and 6, the rear and front transparent plastic plate (2) (4) The direction of travel changes forward.

By the way, there is no processing between the light reflecting groove and the groove of the rear transparent plastic plate (2), that is, the light reflecting groove (3) (3a) cut inclined to one side because there is no obstacle and the light just passes by horizontally. ) Is reflected and refracted by the light, so the front is viewed through brightly, but the part without the light reflecting groove (3) (3a) is only a horizontal amount of light, but the amount of light reflected forward is very small and blurred. Will appear.

However, if the light reflecting grooves 3 and 3a of the front and rear transparent plastic plates 2 and 4 are laminated to be installed alternately with each other, the area where the light is reflected as a whole is the front of each of the rear and front transparent plastic plates. As it is distributed over the entire area, the entire area of the rear and front transparent plastic plates shines with uniform brightness.

On the other hand, the light flowing horizontally along the inside of the rear and front transparent plastic plate (2) (4) is about to leak to the outside through the rear of the rear and front transparent plastic plate (2) (4), at this time the rear transparent The light reflecting film (10) 11 attached to the back of the plastic plate (2) reflects the light and sends it to the front so that the front becomes brighter, and the white and silver light reflecting film (10) (11) By using a double, the light diffusion and straightness is better.

In this way, the light reflected forward through the light reflecting grooves 3 and 3a passes through the advertising film 7, whereby the advertising design 8 developed in the advertising film 7 is a decorative figure. It is projected brightly forward and becomes clear.

In addition, the light emitted from the light sources 6 and 6a on the side is projected through the colored films 9 of different colors, and is reflected forward when passing through the engraved valleys of the decorative shapes 8 to have a specific color outline. The figure is formed to beautifully decorate the outline of the ad text represented by the advertising film 7.
Meanwhile, the rear and front transparent plastic plates 2 and 4 of the present invention are formed of a light guide plate, and thus, an advertisement board or a lamp for advertising using a light source, a light guide plate of a backlight set applied to a liquid crystal display (LCD) of a computer, and the like. It can be used for many purposes.
