Description

The present invention relates to an advertisement board using a light emitting diode (hereinafter referred to as an LED), and more particularly to an improvement of a hanging type constituted by a combination with a transparent acrylic resin board.

In recent years, advertising boards using lighting fixtures with built-in LEDs are becoming popular in store windows and the like. In particular, it is most suitable as a night-time business promotion means such as a hanging sketch of a real estate property in a store.
Conventionally, this type of advertising board is structurally transparent as shown in FIG. 3 with a rectangular transparent first acrylic resin plate (A) and a transparent second acrylic resin plate (B). A third acrylic resin plate (c) and an opaque fourth acrylic resin (d) are superposed and connected integrally with a plurality of predetermined screws (chi). Specifically, the second acrylic resin A groove is provided in the vertical direction on one side of the resin plate (b), and extremely small LED modules (e) are arranged in the groove. In addition, the surface of the third acrylic resin plate is embossed with irregularities to disperse the LED light source by irregular reflection, and the surface of the opaque fourth acrylic resin has a power switch (he ) And connector (g) are connected.

However, the above structure has the following problems.
(1) Since the light emitted from the LED light source is diffusely reflected not only on the opaque acrylic resin plate surface but also on the back surface due to the unevenness (embossed part), the surface on the advertising medium side tends to be dark and light and dark. There is concern that this variation will occur.
(2) There is a problem that the appearance of the surface of the opaque acrylic resin plate is not good because the surface of the unevenness (embossed portion) is raised by the light emission of the LED through the advertising medium (such as promotional printing paper).
{Circle around (3)} Since a plurality of thick acrylic resin plates are used, the weight per piece becomes heavy and the number of suspensions is likely to be limited.

The present invention has been made in view of the above problems, and an advertising medium is set in a gap between one plastic sheet and a transparent main acrylic resin plate.
The newly intervening sub acrylic resin plate is fixed in advance to the main acrylic resin plate which has been embossed with a rough surface, and then the other plastic sheet is fixed. As a result, the advertising medium can be effectively used on both sides of the advertising medium by sandwiching it between one plastic sheet and the main acrylic resin plate and between the other plastic sheet and the sub acrylic resin plate. The object is to be able to eliminate the raised pattern of the irregularities on the surface of the main acrylic resin plate that has occurred by inserting the sub acrylic resin plate.

A magnet film framed in the shape of a frame on the inner surface of two transparent plastic sheets shaped like a rectangular body, and magnet holders are embedded in predetermined positions at the four corners in the same shape as the rectangular body, and have the required thickness A transparent main acrylic resin plate having an extremely small embossed surface and a transparent sub acrylic resin plate (thickness of 1. mm) disposed in a groove formed in either the left or right vertical direction and having an embossed surface. 5 to 2.5 mm), and further, female and male connectors having lead wires wired on a part of the outer surface of the transparent main acrylic resin plate, magnet receiving brackets provided at predetermined positions at four corners, and an upper surface The connecting claw bracket and the lower surface are connected by connecting the connecting bracket with a plurality of screws so that the illuminance from the LED light source can be condensed on the advertising medium and the surface of the acrylic resin plate can be made uneven. Stand out The provision of LED billboard was quenched the pattern.

A new transparent acrylic resin plate is interposed and the unevenness of the main acrylic resin plate is brought into close contact, so that the illuminance can be focused only on the surface of the advertising board due to the change in light refraction of the LED module, thereby making the advertising medium brighter. be able to. Combined with this, the embossing can no longer be seen, and both sides of the advertising medium can be used effectively.

Since the weight of the main body per unit becomes light, the connected number can be hung together and the light collecting property of the LED light source can be improved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view and a side view of an LED advertising board according to the present invention, wherein 1 is a plastic sheet, 2 is an LED module, 3 is a main acrylic resin plate, 4 is a secondary acrylic resin plate, 5 is a female connector, 6 Is a male connector, 7 is a magnet film, 8 is a lead wire, 9 is a screw, 10 is a connection claw bracket, 11 is a connection bracket, 12 is a magnet bracket, and P is an advertising medium.

A plurality of ten connection claw fittings are attached to the upper surface of the three transparent main acrylic resin plates, and 11 corresponding connection fittings are attached to the lower surface.
As for the electrical connection method of the LED advertising board, the two LED modules emit light by the male and female connectors 5 and 6 connected to the 8 lead wires. Of course, the main body of the power source is a system using a commercial AC power supply AC 100V and a direct current adapter (not shown).

FIG. 2 is an enlarged detailed cross-sectional view of the main structure portion of the present invention, and the two LED modules serving as the light emitting portions are arranged in the groove portions 3a of the transparent three main acrylic resin plates. The surface of the transparent 3 main acrylic resin plate is provided with 3b irregularities, covers the transparent 1 plastic sheet, and these lower ends are connected by 9 screws to be integrated.
Twelve magnet brackets are embedded in predetermined positions at the four corners of the rectangular body of the three transparent main acrylic resin plates. Furthermore, similarly, 12 magnet holders are embedded in the same position as the main acrylic resin plate 3 in the newly transparent 4 sub acrylic resin plate (thickness 1.5 to 2.5 mm). Thereby, the 3 main acrylic resin plates and the 4 sub acrylic resin plates are configured so that they can be tightly locked by the 7 magnet films attached to the frame shape on the back side of the plastic sheet of the transparent rectangular body 1.

Printing paper used as an advertising medium for P can be easily set and removed in the gap with the secondary acrylic resin plate with the plastic sheet of the transparent rectangular body 1 open. Can be done freely.

As described above, the LED advertising board of the present invention has been verified based on the results of an actual experiment using an actual machine in order to improve the problems of the conventional products, and those problems can be reliably wiped out. It is.
