Description

Self-charging LED sign using solar light and LED {Standing signboard by using solar battery module}

The present invention relates to a self-rechargeable LED signboard using solar light and LEDs that use solar light as a main energy source and use LED light as an auxiliary energy source even at night, and do not need an extension of a promotional time and a power line.

Signboards are signs, such as names, items, and items sold at shops, companies, offices, and institutions, and are easily visible or attached to people. The signs have been around for a long time. At first, they used their own products as a signboard, but gradually expressed their tastes using letters and pictures. Also, signboards are also called billboards, and their types have been diversified due to the complexity of commercial activities.

These signs include rooftop signs, wall signs, ledge signs, headboard signs, holding signs (signboards), billboards (fields, mountains, highway signs), and neon signs and advertising towers. There are lighting advertising signs, picture signs, plastic signs, and cine signs.

Here, the lighting advertisement sign has been using a fluorescent lamp or a neon light, but recently, the development of LED, the fluorescent or neon lamp that has been widely used in the lighting advertising signage is gradually replaced by high-brightness LED.

On the other hand, the signboard of the signboard is a sign leaning against the wall or standing on the road, mainly used to inform the suburban power cafes, pensions and training centers, orchards, etc. And a power supply unit for supplying power to the fluorescent lamp and the fluorescent lamp provided inside the case.

However, most of the signboards are located far away from the pensions or cafes, so they require quite long wires. To prevent electric shocks, wires must be buried at the time of installation. It is common to install it as it is.

Therefore, the wire may be peeled off by various causes, and if the wire is peeled off, there may be a safety accident during rain.

An object of the present invention is to provide a self-powered signage that does not require wires for safety.

In addition, another object of the present invention to provide a signboard with improved photovoltaic power generation ability using a transparent solar cell.
