Road Traffic Signs are graphical symbols that display traffic regulations and road information. They can make traffic regulations visually, concisely and concisely expressed. At the same time, they also express the content that is difficult to describe in words. They are used to manage traffic and indicate the direction of driving to ensure the smooth flow of roads and the safety of driving. Applicable to highways, urban roads and all special highways, with the nature of the law, vehicles, pedestrians must comply with.

The new product is a combination of LED control technology such as dimming control, temperature management and rain protection measures of TB GROUP and Sumitomo Chemical's light guide plate design technology. It is planned for indoor billboards and luminous wall decoration.
The new product reduces the thickness of the panel to 7.5 mm by arranging an LED light source at the end of the light-emitting surface to diffuse the illumination light through the light guide plate. The power consumption is 5W per panel. The surface illumination (light source) is 3500 lux and the color temperature is 5000 K. It will be sold in spring 2012. 
The standard size of the LED surface light source is 300mm x 600mm each. By extracting light from the end of the panel, the problem of uneven light in the joint portion of the prior art with other panels is reduced. If multiple new products are used in combination, even a large luminous surface can achieve a perfect luminous surface without uneven light.
The new products are designed in a variety of sizes to reduce construction time and increase handling convenience. In addition, in order to improve the convenience of construction, the attachment head is installed on the construction surface and the back of the new product, thereby realizing the standardization of the construction method. 
Recently, at the "4th New Generation Lighting Technology Exhibition", Sumitomo Chemical Co., Ltd. exhibited a light guide plate type with TB GROUP that can realize various sizes of light-emitting surfaces by standardizing the size of LED panels and arranging multiple panels in a matrix.
