Of course, it is also possible to prevent unnecessary power consumption, and also relates to a billboard with a distance-sensing photo sensor that can improve the user's convenience as the lighting is turned on or off without user's manipulation.

In general, advertising is a technology used to attract the public's attention to products, services, sports, etc., and its purpose is to persuade the public to react in a certain way to the contents of the advertisement.

The main media used in such advertisements are newspapers, broadcasts, magazines, mail, posters, public transportation, billboards, etc. The double billboards are installed on the walls of the building, on the upper side of the entrance, or on the rooftop, and are used by companies, shops, offices, and various institutions. It is used to advertise so that it stands out to the human eye by expressing its name, company name, sales product, business item, etc. The shape, function, and configuration are varied, and lighting means inside the billboard to increase the efficiency of the billboard as needed. After installing the advertising content of the billboard in accordance with the lighting means can be emphasized.

The billboard by the lighting means is a general method of connecting a fluorescent lamp, a light emitting diode, an LED bulb, etc. in order to illuminate the lighting, but this is described as a number of problems as follows.

First: In the case of the conventional billboards, the lights are turned on until the lights are turned off at night, so the power costs consumed by the billboards occupy a significant portion of the total power costs. It is also a burden, and in recent years, billboards are gradually increasing in size, so more power is required, so the problem of power use is a big problem not only for individuals but also for society.

second ; As the lighting of the billboard is mainly used at night, the lighting of the billboard should be turned on when the user starts to get dark, and the lighting of the billboard should be turned off when the day is bright. Even though the day was bright, the lighting of the billboard is constantly on, so that the power is consumed unnecessarily, so the user has to turn on or off the lights with care.

Therefore, the present invention has been invented to solve the conventional problems as described above, the object of the present invention is to prevent unnecessary power consumption to reduce the power cost, and also the user to pay attention to the lighting of the billboard Even without turning on or turning off the lighting, the billboard itself is controlled to provide a billboard with a distance sensing photo sensor, which improves user convenience by turning the lighting on or off.

Hereinafter, described in detail by the accompanying drawings the technical configuration and operation of a preferred embodiment that can effectively achieve the above object of the present invention.

1 is an exploded perspective view illustrating a billboard according to the present invention, Figure 2 is a cross-sectional view of the combination of FIG.

The present invention is to configure the billboard so that the advertising content of the image film 500 is displayed on the surface by the lighting means installed on the rear, the center portion 101, the controller 130 and the AC inverter 140 is installed in the center Is formed, the main body 100 is formed with flanges for engaging the flange 120 on the inner side of the wall 110 in all directions;

It is located inside one part of the edge wall 110 of the main body 100, and if the proximity of the human body is not detected within the set range, the power "off" signal to the controller 130 for controlling the AC inverter 140 A distance detecting photo sensor 200 which transmits a power "on" signal to the controller 130 when it senses the proximity of the human body;

The cold cathode fluorescent lamp 410, which is turned on / off under the direction of the controller 130 according to the power “on / off” signal of the distance sensing photo sensor 200, is installed in close contact with both sides of the cold cathode fluorescent lamp. A light guide plate 400 including a lamp 410 and tapered at four sides of the light blocking block 420;

A reflection plate 300 installed between the light guide plate 400 and the main body 100 to reflect the light of the light guide plate 400 to the front;

An image film 500 printed on letters or pictures and installed on the front surface of the light guide plate 400;

When the cold cathode fluorescent lamp 410 of the light guide plate 400 is installed on the front surface of the image film 500 so that the contents of the image film 500 are exposed according to the illumination of the light guide plate 400. A semi-transparent half mirror 600 that reflects an object like a mirror;

Pressing the edge of the half mirror 600, the outgoing hole of the image film 500 is formed in the center, and is composed of the front plate 700 which is bound to the main body 100, reference numeral 720 in the figure is the main body And screw to join the front panel.

The present invention configured as described above is to install the lighting means on the billboard so that the advertising content of the billboard can be clearly displayed even at night due to the illumination to maximize the advertising effect as in the prior art.

However, a feature of the present invention is that the lighting is turned on only when a person comes to the billboard without lighting on at night, so that the advertisement contents are displayed so that there is no conventional viewer, the lighting of the billboard is constantly turned on This unnecessary consumption can be easily solved.

In addition, even if the user does not turn on or turn off the lights with care, the billboard itself can control the on / off of the lighting, thereby improving the user's convenience.

That is, in the advertisement board of the present invention, as illustrated in FIGS. 1 to 2, the controller 130 and the AC inverter 140 are installed in the recess 101 formed in the main body 100, and the reflecting plate 300 is disposed thereon. And the light guide plate 400, the image film 500, and the half mirror (Haif Mirror: 600) are installed in this order. Since the flange portion 120 is formed on the inner surface of the rim wall 110 of the main body 100, the reflection plate 300 is provided. ), The light guide plate 400, the image film 500, and the half mirror 600 are sequentially placed inside the edge wall 110 so that the light guide plate 400, the light guide plate 400, and the light guide plate 400 are overlapped with the flange part 120.

Thereafter, when the front plate 700 is attached to the main body 100 and the screws 720 are assembled, the reflector 300, the light guide plate 400, the image film 500, and the half mirror 600 are the main body 100 and the front surface. There is no deviation between the plates 700.

In addition, a distance sensing photo sensor 200 is installed inside a part of the edge wall 110 of the main body 100. The distance sensing photo sensor 200 is powered by the controller 130 when it is detected that the human body is in proximity. When the "on" signal is sent and the proximity of the human body is not detected, the controller 130 transmits a power "off" signal.

Here, the distance detecting photo sensor 200 does not always recognize only objects located at the same distance, but allows the user to recognize a distance that the distance detecting photo sensor 200 can recognize, that is, a very close object or slightly. The recognition distance can be freely adjusted, for example, to recognize fallen objects.

The light guide plate 400 is provided with a cold cathode fluorescent lamp 410 that is turned on or off according to the instruction of the controller 130, and the cold cathode fluorescent lamp 410 is a light blocking plate 420 as well as the light guide plate 400. Tap the four sides of the edge of the cold cathode fluorescent lamp 410 does not spread in all directions, but is concentrated in the center to brighten the image film 500 more brightly.

Unlike the conventional fluorescent lamp, the cold cathode fluorescent lamp 410 is an ultra-fine cold cathode fluorescent lamp 410 having a diameter of 1.8 to 2.6 mm and reaches 6 times as long as a hot cathode fluorescent lamp with a maximum lifetime of 60,000 hours.

Such a billboard of the present invention, when a person is close, the distance sensing photo sensor 200 detects this and sends a power "on" signal to the controller 130, and the controller 130 receives the signal and receives the AC inverter 140. At the same time, the cold cathode fluorescent lamp 410 is turned on by sending an operation signal to the cold cathode fluorescent lamp 410.

In this case, the light emitted from the cold cathode fluorescent lamp 410 is reflected by all of the light reflected from the rear by the reflector 300, and the light of the cold cathode fluorescent lamp 410 is the light guide plate 400. ) Is uniformly reflected on the image film 500 by

When the cold cathode fluorescent lamp 410 is turned on and the light shines on the image film 500, the contents of the image film 500 are displayed through the half mirror 600 installed in front of the image film 500. The contents of the image film 500 can be recognized from the outside.

The half mirror 600 is a semi-transparent mirror made of chrome to reflect half of the light and half of the light. That is, one side of the mirror has the same property as the glass and the other side of the mirror is controlled on one side. Since the person who sees the other side or sees itself as a mirror because of the cold cathode fluorescent lamp 410, the content of the image film 500 is reflected in the half mirror 600. .

On the contrary, when a person is not in close proximity to the billboard, the distance detecting photo sensor 200 detects this and sends a power "off" signal to the controller 130 to operate the AC inverter 140 and cool at the same time. By sending a signal to the cathode fluorescent lamp 410, the cold cathode fluorescent lamp 410 is turned off.

As such, when the cold cathode fluorescent lamp 410 is turned off, the illumination of the image film 500 disappears, so that the contents of the image film 500 are not expressed through the half mirror 600, and thus the half mirror 600 is removed. It can be used as a normal mirror.

That is, when the outside of the half mirror 600 is brighter than the inside due to the extinguishing of the cold cathode fluorescent lamp 410, since the light reflected from the surface of the half mirror 600 is strong, it can be used as a normal mirror. When the outside of the half mirror 600 is darker than the inside due to the lighting of the cold cathode fluorescent lamp 410, light is transmitted through the half mirror 600 so that the contents of the image film 500 may be recognized. It can be.

And in the billboard of the present invention by forming a sensor ball 710 on the front plate 700 to display the distance sensing photo sensor 200 installed in the main body 100 through the sensor ball 710 while the distance sensing photo sensor ( 200) is installed in place to be able to detect the distance more effectively.

As described above, the billboard of the present invention can not normally recognize the advertising content of the billboard, but when a person approaches the billboard, the lighting of the billboard is automatically turned on, and the advertisement contents are suddenly expressed to attract people's attention to maximize the advertising effect. In addition, the electricity consumption is significantly reduced compared to the conventional billboard which is always lit, so that the electricity bill can be reduced, and the user does not need to turn on or turn off the billboard lighting. It is a very useful invention with improved convenience.
