LED管状灯是以LED为发光源的线状灯饰，它的透光部分为直径50毫米的PC透光圆管，LED发光经圆型内齿PC灯罩的多次折射，视角大，可视性佳，混光均匀，柔和无阴影。采用一次成型防腐蚀氧化处理的铝合金型材作底托结构，铝合金型材壁厚，全封闭的金属支架结构提供完善的防水、防尘、防雷击损坏性能。底托内置CE认证宽范围开关稳压电源（85V到250V），适应长距离灯管联接及全球各地供电使用，恒压恒流12V输出驱动，确保LED长期工作的稳定性。电源线和数据信号线用特制防水性极佳的防水对插接头，采用专业设备对灯管内部电路板作独特的纳米防护技术，两端端盖采用硅橡胶密封处理，防护等级可高达IP67，因此有着超强全天候适应环境能力。每根灯管（1000MM）的像素点数达48个，每个像素点由红、绿、蓝3个超高亮LED组成，LED可选择平头食人鱼，草帽型，贴片SMD等封装的LED，LED总数为144个，光色亮丽，饱和度高。可采用带DMX512接口的全彩控制器对灯管进行单点全辉度控制，也可接全彩视频控制器实时播放各种视频节目。可以广泛应用于桥梁、河道护栏，楼宇外墙等城市亮化景观照明。

LED guardrail light is a tube lighting of LED light source. The transparent part to light is round PC tube of Diameter 50 mm. By several refractions of inner-toothed PC shell, LED emits soft, well-proportional light. Our LED guardrail light is characterized as wide and well viewing-angle without shadow. It adopts molding-once anti-eroding oxidation treatment aluminum alloy bracket structure. Full-close thick metal structure has the abilities of perfect waterproof, dustproof and anti-thunder strike. CE approved inner switch regular power of wide range (from 85V to 250V) guarantees the long connection of tubes and meets worldwide standard power supply. 12 V regular voltage input driving ensures stable long-term work of LED. Power cord and signal cord are of special waterproof end-to-end connectors. The PCB in the tube is treated with special nono protection technology. After using silicon rubber to seal the end cap, the protection grade could reach up to IP67. So it possesses the ability to completely suite for all weather. The pixels of each 1000mm long tube are 48 and each pixel consists of red, green and yellow ultra bright LED, where the available LEDs are flat super flux, cap and SMD. 144 pcs LEDs make tube bright and saturate. It could using DMX512 full color controller to control single dot in whole gray scale, and also using full color video controller to synchronous display various video program. It is widely used in brightening bridge, guardrail of river way, out wall of buildings.
