Description

Road sign bottle using LED {LOAD SAFETY INDICATOR USING LIGHT EMITTING DIODE}

The present invention relates to a road sign bottle using the LED, and more particularly to a road sign bottle using the LED for transmitting information as an LED so that pedestrians and drivers can recognize the control signals such as pedestrian crossing and crosswalk traffic lights at night. .

A road sign is a road attachment in accordance with Article 3 of the Road Act and Article 30 of the Regulations on Structural / Facility Standards, which compensates for the severe deterioration of visibility at night or in the rain, and clearly induces the driver's attention. Refers to an eye-guided facility for promoting smooth communication. Therefore, road markers are appropriately installed in areas that need to supplement the functions of road markings such as road center lines, lane boundaries, dedicated lanes, roadblocks, and safety zones and to increase the driver's awareness of linear guidance or changes in road conditions. Edge zone lines, sharp curves, tunnels, lane reduction / separation / join sections, traffic lane changes, traffic islands, interchanges, two-way roads including left turn lanes, physically undivided lanes, narrow bridges, etc. Is a typical installation section of road marking bottles.

A general road sign bottle is divided into a reflective type and a light emitting type according to a driving method, and the light emitting type is further divided into a flashing type, a lighting type, a switching type, and the like. Reflective road signs do not have a self-illuminating function, which reflects the headlights of a car to perform the function. Because of the relatively inexpensive and easy installation, in order to implement a reflective surface at a predetermined angle, it must be installed to protrude from the road surface to a certain extent, thereby degrading stability and running performance and shortening the life due to wear of the reflective surface. As a result, it is currently used only in limited fields such as temporary lane marking.

On the other hand, the light emitting road sign bottle is a light source such as a light-emitting diode (LED) is built in, it is possible to self-light.

Therefore, it can be buried in the ground so as not to be exposed from the road surface, so it has high stability and running ability and has a relatively long life, thereby reducing the cost of longer maintenance periods and reducing the effort and effort required for maintenance. Most road signs are light-emitting.

Recently, many attempts have been made to use high-efficiency LEDs as light sources to increase the power efficiency of light-emitting road signs. However, the problem of the light emitting road sign bottle has a lot of difficulties in the maintenance due to the installation of power lines to supply power and frequent road maintenance. Therefore, in order to solve such a problem of power supply, a battery-integrated LED road sign bottle with a built-in battery has been proposed, but there are many inconveniences due to frequent replacement of batteries, which requires improvement.

In addition, the LED has a strong light straightness, so the angle of recognition of the LED road sign bottle is narrow, so it needs a diffusion structure that can diffuse light efficiently, and it is necessary to replace the broken road sign bottle or repair the broken road sign bottle. In order to replace the landfill, it is possible only to dig the road around the landfill, and the inconvenience of having to repackage the road after landfill requires a structure that can be quickly removed and installed road marker bottles.

Accordingly, recently, technologies for LED road sign bottles using solar energy have been developed.

However, such a road marker bottle is limited in its use since it is impossible to accumulate electrical energy when a situation in which sunlight does not accumulate energy for a long period of time such as rainy weather occurs. In addition, when the road sign bottle is used in a crosswalk, etc., there is a problem that a high installation cost is required because the road sign bottle for the driver and the road sign bottle for the pedestrian must be installed respectively.

Accordingly, an object of the present invention is to display the position of the crosswalk to the driver of the vehicle that can not directly determine the crosswalk to help the driver to drive safely, and to move to a pedestrian in a situation where it is difficult to check the traffic light directly. To help the pedestrians move by telling them, it is to provide a road sign using LED that eliminates the difficulty of power supply.
