Description

Back light and advertisement system utilizing the same

The present invention relates to an advertisement apparatus, and more particularly, to an advertisement apparatus using a light emitting diode capable of color implementation.

In general, in order to deliver various product sales information such as product advertisements, business advertisements, sale advertisements of large stores, etc. to buyers, flyers, billboards, self-emitting advertising devices, and mass media are used.

The flyer or menu information sheet can be easily delivered to the public and is used because it is relatively inexpensive, but most of them are one-time advertisements, so it is difficult to expect a great effect. In view of this, signboards and billboards are installed on the outside of shops, in shops or in public places, and in elevators for long-term advertisements.

However, the advertisement using the billboard has visual effects such as expression color, but it is extremely flat, so it is difficult to advertise various patterns and it is not easy for the consumers to focus their attention. In consideration of this point, advertisements using neon signs, image display devices, etc. are being made. When the neon signs are used, the neon tubes are banded in a pattern to be advertised. It gives a feeling and power consumption is high because a relatively high voltage is required to emit a neon tube. In the case of the image display device, various images and colors can be implemented, and thus a relatively large advertisement effect can be expected, but high power consumption and high production cost are not easy to disseminate.

Advertisement apparatus according to the present invention can improve visibility by irradiating dynamic lighting to static advertising phrases and drawings by using a backlight using a light emitting diode that can implement a variety of color light as shown in FIG. 1 and FIG. 2 is shown.

Referring to the drawings, the advertisement apparatus 10 using the backlight includes a backlight 20 installed in the frame 11 and a diffusion plate installed on the front of the backlight 20 to diffuse light emitted from the backlight 20. 40 and an advertisement sheet 50 installed on the front of the diffusion plate 40 and having an advertisement pattern, that is, a phrase or a pattern for advertisement. The cover member 12 may further include a cover member 12 coupled to the frame 11 and having an opening to expose the advertisement pattern and surrounding the components.

The advertising device 10 configured as described above will be described in more detail by component.

As shown in FIGS. 1 and 2, the backlight 20 may be installed in the frame 11 to implement back light of various colors, and a plurality of light emitting diodes 21 capable of implementing color light may be provided. At least one circuit board 22 or 22 provided in a predetermined pattern and a driving unit 30 for driving the light emitting diodes 21 supported by the circuit boards 22 and 22 are provided. The circuit boards 22 and 22 may be formed in a stripe shape as shown in FIGS. 1 and 4, or may be formed in a shape of letters or designs for advertisement as shown in FIG. 3. The shape of the circuit boards 22 and 22 is not limited to the above-described embodiments and can be modified in various forms. In addition, the surfaces of the circuit boards 22 and 22 may be formed in white to reflect light generated from the light emitting diodes 21 to the front side, and the rear surface of the circuit boards 22 and 22 may be formed of light. It is desirable to have a black color to block the transmission. A reflective film 22a may be formed on the front surface of the circuit boards 22 and 22 and a blocking film (not shown) may be formed on the back surface of the circuit board to block light.

On the other hand, the light emitting diodes 21 installed on the circuit boards 22 and 22 are light emitting diodes in which red, blue, and green light emitting parts are packaged so as to realize full color light. However, the light emitting diodes may individually implement red, green, and blue light emitting diodes so as to realize light of various colors, thereby enabling the implementation of selective full color light colors. The array of light emitting diodes 21 provided on the circuit boards 22 and 22 may be formed in a stripe shape, but is not limited thereto. For example, in the case where the shape of the circuit boards 22 and 22 is in the form of an advertisement or a design as described above, the light emitting diodes 21 are arranged along the shape of the circuit boards 22 and 22. The light emitting diodes 21 arranged at this time are preferably arranged densely to have a light emitting pattern in the shape of the circuit boards 22 and 22.

In addition, the driver 10 for driving the light emitting diodes 21 mounted on the circuit board includes a driving driver 31 for selectively driving the light emitting diodes according to a control signal as shown in FIG. 2, and a light emitting diode ( And an input means 32 for selecting the light emitting pattern of 21. The input means 32 selects the number of colors and operation patterns that can be set in eight circuits by using an eight-circuit dip switch so that a user can easily select an advertisement effect.

And a controller 33 for controlling the driving driver 31 to drive the light emitting diodes 21 to correspond to a light emitting pattern selection signal input from the input means 32. The drive driver 31 adopts a contactless switch circuit as a driver circuit of a high brightness light emitting diode used for on-off of the light emitting diode. The controller 33 may include a microcontroller processor 33a and an oscillator 33b.

The diffusion plate 40 is installed on the front surface of the backlight 20 to be in contact with or in proximity to the light emitting diodes 21 installed on the circuit board 22 to radiate light emitted from the light emitting diodes 21. Diffusion is made to have a uniform illuminance in the light emitting region. The diffusion plate 40 has a groove having a predetermined pattern for scattering light or a printing pattern for scattering light on one side of the transparent synthetic resin material. In addition, the diffusion plate may be made of a translucent synthetic resin material.

The advertising film 50 is installed or in close contact with the advertisement plate is printed on a transparent or translucent material to approach the diffusion plate. The advertising film may be modified in various forms in order to increase the advertising effect. Advertising text may be produced in a different color from the announcement film. When the arrangement of the circuit board 22 or the light emitting diodes 21 is formed in a shape corresponding to an advertisement phrase or a design, the separate advertisement film may not be required.

Referring to the operation of the other advertising device and the backlight operation through the present invention configured as described above are as follows.

First, light emitting diodes selectively emit light by supplying power to drive the advertising device 10, and light emitted from the light emitting diodes 21 is radiated onto the diffusion plate 40 and the advertising film 50. Therefore, the advertising phrase and the pattern is emitted by the light passing through the advertising film 50, it is possible to expect the advertising effect. In this process, the light emitting diode is controlled by selecting a predetermined light emitting pattern by using a dip switch, which is an input means 32, so as to produce an advertisement effect selected by the microcontroller processor 33a constituting the control unit 33. Various dynamic light emitting patterns can be realized.

For example, when the circuit board 22 is formed in a plurality of stripes in the process of driving the advertisement device, various full color lights such as a pattern or a flashing pattern flowing at a predetermined interval may be implemented.

And if the shape of the circuit board on which the light emitting diode is installed or the array pattern of the light emitting diodes arranged on the circuit board is formed in a shape consistent with the advertising phrase or design, the phrase itself because the array pattern of the light emitting diode itself forms a single advertising phrase By changing the emission color of the glass, the visibility can be improved and a relatively large announcement effect can be expected.

As described above, the backlight and the advertisement apparatus using the same according to the present invention can expect the following effects.

first; By replacing the commonly used backlight lamps with light emitting diodes in cold cathode light emitting tubes and fluorescent lamps, the lifespan and power consumption can be greatly reduced.

second; By using the controller, the light emitting diodes can be emitted in various patterns, thereby maximizing the advertisement effect.

third; The LED can be driven in various patterns desired by the user for the advertising effect, thereby increasing the user's satisfaction.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

Therefore, the true scope of protection should be defined only by the appended claims.
