    • A dustproof lens for an LED road lamp has an incident surface and an exit surface. The exit surface is flat. The incident surface is saddle-shaped and has a section in a shape of a concave curve along a road direction and in a shape of a convex curve vertically to the road direction. A lens module thereof has the dustproof lenses jointed with each other and has an integrally flat exit plane. The dustproof lens and its module, while meeting requirements in distributing lights for road lighting, adopt a flat surface for emitting lights, in such a manner that the lens is protected from dusts piled up thereon, can be cleaned simply, and is better fit for using. By accomplishing modularization of the lens module in production and assembly, a productive efficiency of lamps is greatly improved.
    • LED路灯的防尘透镜具有入射面和出射面。 出口表面平坦。 入射面为鞍状,具有沿道路方向的凹曲线形状和与道路方向垂直的凸曲线的形状。 其透镜模块具有彼此接合的防尘透镜,并且具有整体平坦的出射面。 防尘透镜及其模块在满足道路照明配光要求的同时,采用平面发光,防止透镜被灰尘堆积在其上,可以简单清洗,更适合 使用。 通过在生产和组装中实现镜头模块的模块化,大大提高了灯的生产效率。
