Description

Outdoor advertising apparatus using EL sheet

The present invention relates to an outdoor advertising device using EL (Electronic Luminance) sheet, in particular to achieve a stable advertising effect while reducing the power cost by supplying power using a solar cell.

Conventional advertising devices such as outdoor billboards to form a picture for advertising on one side of the acrylic plate, such as fluorescent lights in the inner space or by installing a plurality of lighting devices around the billboard to easily identify the pattern at night.

However, in order to be able to identify such an advertisement device at night, it consumes a lot of power, which requires a lot of maintenance costs. Also, a large number of outdoor advertisement devices are installed in a field or a mountain peak where it is difficult to supply electricity. There was a drawback in that the initial installation cost is very high, such as to have to be, and there is a problem that you have to take care of the inconvenience of replacing the lamp.

The present invention has been made to solve the above-mentioned conventional problems, by making a billboard using an EL sheet with relatively low power consumption and is supplied by supplying the EL sheet with the power of a solar cell that is generated using solar light. By reducing the cost of installation and maintenance.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, the same components have the same reference numerals as much as possible even though they are shown in different drawings.

1 to 5 show the configuration of the advertisement device using the EL sheet according to the present invention.

According to the drawings, the advertisement device using the EL sheet of the present invention, the billboard 10 made of an EL sheet 12 having a predetermined width and length on which one or both sides of the phrase or pattern is designed and the aspect having a predetermined standard Inverter 30 to induce lighting of EL sheet 12 stably by changing the current of direct current with charging device 20 and direct current that accumulate current generated by combining a plurality of panel 22 into storage battery 24 to alternating current and It is a configuration consisting of a control device 40 for controlling the operation of the charging device 20 and the inverter 30.

At least one support 14 is formed at the side or bottom of the billboard 10 so that the billboard 10 is firmly embedded by being embedded in the ground or fixed to a wall.

The solar panel 22 is attached to the upper end of the billboard 10 as shown in Figure 2 is preferably configured to be configured to flow the light collecting surface in accordance with the movement of the sun, the automatic regulator to move along the light source ( Not shown) can be employed.

At this time, since the current generated from the solar panel 22 varies in magnitude depending on the irradiation amount of light, the voltage of the generated current is always measured as shown in FIG. When only a current is discharged, when the day is cloudy or rain or snow, the corrector 26 is operated when a voltage is generated below a proper level so that a proper current is always generated.

In particular, when the electricity generated from the solar panel 22 is stored in the storage battery 24, it is possible to install a reverse current protection device to prevent the loss of current due to reverse current.

The solar panel 22 can be appropriately increased or decreased according to the size of the advertising panel 10. According to the experimental example, one solar panel 22 module produced as a standard product has a length and a width of 1 meter and 1.5 meter, respectively. EL sheet 12 of the billboard 10 can be lit.

In addition, CMOS (Complementary Metal Oxide Semiconductor), which is a type of integrated circuit having a MOS structure that is oriented in a trans type and features low power consumption to minimize the consumption of its own current due to the driving of the charging device 20. By adopting a semiconductor with a main axis as the main axis, it is possible to minimize the volume and to obtain stable operation.In order to prevent external abnormal voltage inflow, SCR (Silicon Controlled Rectifier) and TNR element are adopted It can prevent the breakage of.

The inverter 30 converts the direct current supplied from the solar panel 22 or the storage battery 24 into alternating current and supplies the EL sheet 12 to the EL sheet 12 so that the EL sheet 12 is turned on. By adopting semiconductor components such as FET (Field Effect Transistor), it is possible to produce sinusoidal wave which is relatively stable alternating current, and it is easy to install and handle by reducing volume and weight.

In this case, the inverter 30 may prevent the life of the battery 24 and the EL sheet 12 from being shortened by employing an overload and low load protection function to automatically cut off the operation when the incoming current is excessive or insufficient.

In particular, it is possible to install the adjusting device to artificially adjust the brightness of the EL sheet 12.

The control device 40 is a central processing unit that controls all devices such as the charging device 20 and the inverter 30 as shown in FIGS. 3 and 4. When the signal is interrupted by receiving a signal from the photoresist) and the signal is interrupted due to dim or blurred, the charging device 20 is stopped and the inverter 30 is operated. It is to be turned on.

In particular, the control device 40 may adopt the radio transceiver 42 so that it can be adjusted remotely, as shown in FIG. 5, and may be controlled by the timer 44.

As described above, the advertisement device using EL sheet according to the present invention has the advantage that the billboard can be placed on the field or the top of the mountain without the power line construction for supplying power, and the cost of management and maintenance is low. will be.
