The invention discloses a LED flexible light guide device, which comprises a flexible light guide film, a LED chip array and a reflective layer. The LED chip array is embedded in the flexible light guide film, and the reflecting layer is arranged on the back side of the flexible light guide film to reflect the light to the front side of the device. The LED chip has the light surface and the light surface perpendicular to the light guide film, and the scattering is completed in the flexible light guide film. The invention has a built-in LED chip in the light guide plate. No matter how large the area is, it can achieve high brightness. The LED lamp is embedded in the flexible light guide plate. The brightness is independent of the area. It can be used for free clipping. The damaged LED chip or flexible light guide plate can be directly cut off and then used. When the LED chip embedded in different regions of the light guide is different, the color can be changed. The invention can be attached to the surface, installed, rolled and transported, transported and installed conveniently, the size can be made large and the brightness is high, the whole light guide plate has uniform temperature and uniform brightness, and the power drive can be programmed, and the local brightness and color can be adjusted.

一种LED柔性导光装置
本专利技术涉及导光板灯箱,尤其是涉及一种采用柔性材料为基底,透明导电材料为导线的LED柔性导光板。
技术介绍
LED导光板是目前展览展示领域常用的元器件,其结构一般是以刻有散射点的亚克力平板为基础,在侧面安装LED灯条。LED灯条发出的光进入亚克力板后,全反射向前行进,当遇到散射点,光从正面散射;由于散射点数量多且成规律状分布,整个导光板呈面光源形式。例如,专利“一种LED导光板两边封条结构”(申请号为CN201610499883.4)、专利“一种LED导光玻璃”(申请号为CN201621219988.1)。现有技术中的LED灯均设置于侧边,即采用侧面导入光的方式,但随着面积的增加,光源功率需要不断增加,事实上,光源允许功率是有限的,因此,大面积时,亮度比较低。同时,当要求面积小一些时候,无法自由裁剪使用。一般地,市场上的LED导光板是硬质的,如亚克力板,需要一块一块地安装,因此,安装并不方便,同时其缝隙很难填充,限制了LED导光板向大尺寸方向发展。专利“一种大幅面高亮度LED导光板超薄灯箱”(申请号为CN201610983913.9)公开 ...
