Description

Street name sign system {system for Street Name Sign}

The present invention relates to a street sign system, and more particularly, to store electrical energy generated by using solar light and use it as a power source for light emission of a street sign plate, which has excellent aesthetics and saves power. It relates to a street sign system that can control the lighting of the light emitting device by the control.

Street signboards are milestones that are installed at intersections or roads where cars or pedestrians pass to guide street names, building numbers, and directions.

FIG. 1A illustrates a conventional plate type road name plate. In general, a street name sign including a road name plate and a building number plate has a disadvantage in that its contents are difficult to identify at night except when illuminated by a car headlight or a street lamp. .

This is also the case for horizontal sign without using reflected light.

In order to make such a road nameplate visible at night, when lighting is installed on the road nameplate outside the road nameplate, both sides must be illuminated and there is an inefficient disadvantage in that it consumes a lot of power for lighting.

In order to solve this problem, as shown in FIG. 1B, the lighting is installed inside, so that the letters or symbols displayed on the surface of the road name plate can be seen at night. I grew in size and had a problem of hurting aesthetics.

In addition, in recent years, the installation of LEDs in traffic lights is increasing, and the number of the letters or symbols can be identified in order to guide the street name, building number, direction by placing the LEDs in the form of letters or symbols by applying this. It requires a light source and has the disadvantage that the letters or symbols expressed are not smooth.

Among the related technologies, the light emitting diode type backlight advertisement signage (Korean Patent Laid-Open Publication No. 2007-0017927) has a main body having a rectangular box shape with an open front and rear surfaces, and diffuses the light irradiated from the light emitting diodes so that the backlight is made. A technique using a light guide plate and a reflecting plate is disclosed.

As described above, only one side of the light guide plate is provided with a groove, and a reflection plate is provided to advertise only one side.

In the present invention, the horizontal name is not seen in the opposite direction by using one light guide plate without using two light guide plates. We want to reduce costs by making it possible.

In addition, the light guide plate is not attached to both edge members, but is simply inserted into the guide protrusion into the guide groove, and is intended to be easily installed and separated by being fixed to the guide groove.

In addition, by installing a closing cap at both ends of the frame member to prevent the separation of the light guide plate and the light emitting device.

Finally, the dehumidifier insertion groove is formed inside the light emitting device insertion groove, and the dehumidification member filled with the dehumidifier is installed to dehumidify the space between the light guide plate and the edge member to prevent the light emitting device from being shorted or discharged due to condensation. .

A lighting signal is generated by the lighting signal generator so that the lighting can be performed quickly.

When the lighting time is set, the lighting of the LED is controlled according to the lighting time, which is not required to send a lighting signal every day. Since the information is stored in the memory unit and the lighting is performed according to the control of the central control unit, the cost for communication is reduced and the central control is smoothly performed.

In addition, in the case of temporarily turning on according to the sunshine conditions, the LED can be turned on according to the lighting signal, which is temporarily changed in accordance with the sunshine conditions that change due to the weather, etc. in addition to the lighting of the set LED according to the change of sunshine time according to the season. By enabling to turn on, to provide an advantage that can actively cope with the surrounding environment.

The central control unit may generate a state signal including an electrical energy output state from the photovoltaic unit, a power storage state of the power storage unit, a lighting state of the LED, illuminance information, and the like, and transmit the corresponding state signal to the central control unit. As another example, a status signal is responded to at the request of the central control means.

The reason for transmitting the status signal as described above is to allow the central control means for managing at least one device of at least one road noun to check in real time the state of each road noun device.

At this time, the state through the display of the central control means will be able to check the remote.

On the other hand, it may be configured to include a memory unit for storing the specific illuminance value information described above, the lighting time information according to the change of the set sunshine time of each season.
