Photovoltaic non-electric billboard billboard street lighting equipment {omitted}

The present invention relates to a photovoltaic non-electric billboard street lamp apparatus. More specifically, the advertisement display can be combined with the illumination lamp to perform an advertisement function in addition to the lighting function, the installation cost can be reduced, and the multi-angle solar cell module can be provided on the top of the granularity, , It is possible to realize the street lamp with its own energy by installing the electric power to the load of the lamp, and by installing the electric shock prevention device in the granular state, even if the granular state such as the street lamp or the traffic light is submerged, the current flowing to the human body can be substantially reduced Which is a photovoltaic-based non-electric-powered billboard.

Lighting is closely related to human life. In addition to the primary functions of lighting to illuminate dark spaces, lighting is used in various fields as well as during nighttime as well as during the daytime. In addition to message transmission, risk communication, aesthetic expression and advertising,

In general, incandescent lamps, fluorescent lamps, sodium lamps, and metal halide lamps have been widely used as lighting. Recently, however, the use range of LEDs has been gradually increasing.

LED is a new technology that uses semiconductor devices for lighting. It has low power consumption, semi-permanent life span, and is able to produce various colors as well as control stepwise brightness. In addition, LEDs meet the trend of low carbon green growth with high light conversion efficiency, no mercury, and low carbon dioxide emissions.

On the other hand, the advertising display is installed in various places such as a subway platform, a bus interior, a train history, a public institution, and catches the attention of people waiting or passing by for a while.

These advertising displays are installed separately in the form of a monitor, which increases the installation cost and is installed in most bright indoor space, so there is a limit in frequency of use in outdoor without lighting at night.

On the other hand, much research has been done on renewable energy such as wind power, wave power, and photovoltaic power generation as a measure against exhaustion of fossil fuels and global warming. Of these, solar cells are a typical example of a power generation method using solar light. Solar cells use solar energy, which is an infinite clean energy, as an energy source to produce electrical energy, and generally use semiconductor devices.

On the other hand, a power supply line drawn out from the ground is electrically connected to a power supply line electrically connected to a lamp provided on the upper part of the granular stand and connected to a power supply. Localness The concentration of rainfall rapidly increases due to heavy rainfall, so that when the water level on the ground increases, the contact point can be submerged. At this time, when a human body touches a metal pipe or the like which is energized through the water or water, an electric current flows to the ground surface through the water and the human body. At this time, the human body is likely to be wet with rain, and in this case, the contact resistance is extremely low, which is very dangerous.

Developing a streetlight technology that can be driven by using energy to produce by itself, by integrating advertising display with a streetlight so that it can perform advertising function in addition to lighting function, A necessity arises.

In addition, the lamp unit 100 is branched in the standing frame 10, and a display billboard 120 is installed. 1, the display billboard 120 is installed on one side of the standing frame 10, but it goes without saying that the display billboard may be provided on one side of the lamp part. Here, the position of the display billboard is not limited.

In addition, an electric shock prevention device is provided inside the granular shaft 10, which will be described later.

The lamp unit 100 includes a plurality of LED modules, a lens for covering the LED modules in front of the LED modules, and a power supply unit for supplying power to the LED modules at the rear of the LED modules. The lamp unit 100 is formed so as to be branched from the granular casting 10 and adjustable in direction and angle.

For example, in order to adjust the direction of the lamp unit 100, the branch unit 102, on which the lamp unit 100 is mounted, may be rotated around the granular shaft 10, But is not limited to.

For example, in order to adjust the angle of the lamp unit 100, the branch unit 102 on which the lamp unit 100 is mounted may be rotated in the vertical direction with respect to the standing frame 10, But does not limit the method.

The multi-angle solar cell module 110 is provided at the upper end of the granular casting 10. The multi-angle solar cell module 110 is formed such that a plurality of solar cell modules are arranged in a hemispherical shape so that sunlight can be incident on the multi-angle solar cell module 110 in various angles. The multi-angle solar cell module 110 produces electric power to be supplied to the power supply unit of the lamp unit 100.

That is, a high-efficiency high-power RGB light source module and a full color LED lighting device are used, and a specific shape is arranged on a display billboard and an advertisement is implemented by irradiating RGB LEDs from the rear.

Hereinafter, an electric shock prevention device provided inside the granular casting 10 will be described with reference to FIGS. 2 and 3. FIG.

Referring to FIG. 2, there is shown an embodiment in which only one pair of flat-plate-shaped conductors among the anti-shock devices according to the present invention is formed.

2, a pair of planar conductors 42 and 44 are provided inside a standing upright 10 of an electric shock prevention apparatus according to a first embodiment of the present invention.

The standing frame 10 is installed on the floor including the floor and can be used in various fields such as lighting, traffic signals, display, voice broadcasting, and the like.

The first flat plate-like conductor 42 is electrically connected between the input-side first wire 22 and the output-side first wire 32, respectively. That is, one end of the first flat plate-like conductor 42 is electrically connected to the input-side first electric wire 22 and the other end is electrically connected to the output-side first electric wire 32.

The first input wire 22 is drawn into the ground 10 from the ground or the ground and supplies power to the loads such as the lamp unit 100 and the display billboard 120 on the granular ground 10. 2 and 3 illustrate an example in which the input-side first electric wire 22 is drawn out from the ground into the granular main body 10, but it is needless to say that power can be supplied through the ground or the ground.

The first output wire 32 is electrically connected to a load such as a lamp unit, a speaker, and a display billboard, and supplies power to the load.

The width of the first flat plate-like conductor 42 is larger than the thickness of at least one of the input-side first wire 22 and the output-side first wire 32 and the length is longer than the width of the input-side first wire 22 and the output- 32, respectively. The area multiplied by the width and the length of the first flat plate-like conductor 42 is preferably at least four times the cross-sectional area of at least one of the first input-side wire 22 and the first output-side wire 32.

The second flat plate-like conductor 44 is electrically connected between the input-side second electric wire 24 and the output-side second electric wire 34, respectively.

The input-side second electric wire 24 is drawn out from the ground or from the ground into the granular main shaft 10 to supply power to a load such as a lamp portion on the granular main shaft 10. Similarly, it is needless to say that the input-side second electric wire 24 can supply power not only through the ground but also through the ground or the ground.

The output-side second wire 34 is electrically connected to a load such as a lamp unit, a speaker, and a display billboard to supply power to the load, and is usually located inside the granular weir 10.

The width of the second flat plate-like conductor 44 is larger than the thickness of at least one of the input-side second wire 24 and the output-side second wire 34, and the length is longer than the width of the input- 34, respectively. It is preferable that an area multiplied by the width and the length of the second flat plate-like conductor 44 is at least four times the cross-sectional area of at least one of the input-side second wire 24 and the output-side second wire 34.

The input side first wire 22 and the output side first wire 32 and the input side second wire 24 and the output side second wire 34 are physically and electrically formed to have the same standard. It is not. Since the electric shock prevention device is installed in the transmission and distribution path, the first input-side cable and the first output-side electric wire are physically and electrically identical to each other, and the input-side second electric wire and the output-side second electric wire are physically and electrically identical wires. However, the present invention is not limited thereto.

Usually, the first plate-like conductor 42 and the second plate-like conductor 44 are formed of the same material and the same material, but the present invention is not limited thereto.

The first plate-like conductor 42 and the second plate-like conductor 44 are electrically separated from each other and physically spaced apart from each other. Although the present invention can not be fully explained by the theory of electric circuits, the electric shock prevention device according to the present invention, when viewed from the electrical point of view, causes water to be caught between two flat plate-like conductors when immersed in water, Which is formed by the water present in the electrode. Since the electrical resistance is proportional to the length of the resistor and inversely proportional to the cross-sectional area, the cross-sectional area becomes the maximum when the planar conductors face each other, the length becomes minimum, and the electrical resistance becomes minimum. Thus, when connected in parallel to the human body and the ground plane, the current flowing to a human body having a higher resistance can be minimized.

On the other hand, the electric shock preventer according to the present invention is installed in a state in which the first plate-like conductor and the second plate-like conductor are opposed to each other, and is installed at a lower position than the target electric appliance to be protected from flooding. For example, in the case of a streetlight, the controller exposed to the lower part is installed in a waterproof space. However, if rainwater or the like gets in the space, people around the house are in danger of electric shock. The electric shock preventive device is installed in the waterproof space and is installed at a position lower than the controller, so that the controller floods before the flooding, thereby enabling the controller to operate first.

The first flat-plate-like conductor and the second flat-plate-like conductor are physically fixed inside the granular cage. 2 and 3 are applied to a two-wire system, two planar conductors are fixed, but in the case of a three-wire system, three planar conductors are fixed. Although not shown, such a flat type conductor can be fixed to a separate housing, and the housing can be made of non-conductive plastic or ceramic material.

Preferably, the material of the first plate-like conductor and the second plate-like conductor is copper (Cu). According to the experiment, the effect of minimizing the current flowing from the battery to the printed circuit board or the like was excellent when the material of the flat plate type conductor was copper rather than iron or aluminum.

Experiments on the present invention can be designed with the following structure.

After the water tank is filled with water and the bottom of the granule is immersed in the water, the tester can measure the current flowing through the electric wire with an ammeter while holding the exposed end of the wire and immersing the other end in the water tank.

The middle part of the electrical resistor called water between the two plate-like conductors can be modeled electrically in a grounded state. The human body can be modeled as another resistor connected between this electrical resistor and the ground plane. The resistive body, which is a human body, and the water resistors connected between the two planar conductors and the ground plane are electrically connected in parallel to limit the current flowing into the human body, which can be understood as a conventional electric circuit analysis.

The current flowing through the human body is related to the ratio of the area of the flat plate-like conductor to the cross-sectional area of the cylindrical wires (the first wire and the second wire). Here, the area of the plate-like conductor refers to a value obtained by multiplying the width and the length of the plate-like conductor in the shape of a plate. Since the cross-sectional area of the cylindrical wire when referred πr ² width 2r, an area ratio of ^{r 2, 2r 2, 4r 2} , 8r 2, 16r 2 that the wire cross-sectional area to the area of the plate-like conductor or the like of the plate-like conductor π / 1, π / 2, π / 4, π / 8, and π / 16. As a result of the experiment, when the area of the planar conductor is four times or more the cross-sectional area of the cylindrical wire, it is confirmed that the current flows to the human body in a normal state.

The embodiment of FIG. 3 is similar to the embodiment of FIG. 2 except that a pair of planar conductors is grounded, so that the difference will be mainly described.

3, in the electric shock preventing device according to another embodiment of the present invention, the grounding conductor 50 is inserted between the first plate-like conductor 42 and the second plate-like conductor 44 . At this time, the grounding line 52 is electrically connected to one end (lower end in reference to FIG. 3) of the grounding conductor 50, and the grounding line 52 is grounded.

As shown in FIG. 3, it is experimentally confirmed that even if only a pair of the planar conductors are provided, it is possible to sufficiently prevent the electric shock. However, in the case where the grounding conductor is additionally provided as shown in FIG. 3, do.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be. Therefore, the embodiments disclosed in the present invention and the accompanying drawings are intended to illustrate and not to limit the technical spirit of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments and the accompanying drawings .
