Description

Solar Road Sign and Spectacle Lighting {A Road Sign and Spectacle Iluminating LED With Solar Cell}

The present invention relates to road signs and landscapes, and more particularly, to be able to recognize main signs of a road such as lane identification of a road at night after being charged by sunlight to operate without supplying power from the outside. Solar LED road signs and landscape lights that beautifully illuminate the exterior of the building.

A road sign is a road attachment under 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 draws 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, reduced / separated / joined sections of lanes, altered sections of traffic lanes, two-way roads including traffic islands, interchanges, left turn lanes, multi-lane roads that are not physically separated, bridges with folded width The back corresponds to 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 self-luminous is possible. 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.

Many attempts have been made to use high-efficiency LEDs as light sources to increase the power efficiency of luminous road sign bottles. However, the problem with luminous road sign bottles is the maintenance of installation due to the installation of power lines to supply electricity and frequent road maintenance. There are many difficulties. 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 straightness of light, so the angle of recognition of the LED road sign bottle is very narrow and requires a diffusion structure that can diffuse light efficiently, and replaces the broken road sign bottle or repairs a broken road sign bottle. In order to replace the landfill type, since the landfill type can only be dug around the road, there is an inconvenience of resurfacing the road after landfill, and thus a structure capable of removing and installing the road marker bottle more quickly is required.

In addition, when the weather is cold in winter, condensation may occur around the LED, preventing the light from being visible due to obstruction of light emission, and thus an improvement is required.

On the other hand, solar LED road signs and landscape lights are attached to the exterior walls of convenience facilities, such as buildings, so that solar LED landscape lights are installed on the main parts of the facilities and surrounding landscapes to create a more atmospheric night view for users who use the convenience facilities. By illuminating the facility, it is proposed to attach it to the outer wall of a building to create a more mysterious and beautiful night view, but there is a difficulty in electrical wiring and detachment for replacement during maintenance. .
