The utility model discloses a light mixing and color mixing small angle lens for wall washing, including a lens body, which comprises a lens mounting seat, a lens body arranged in the lens mounting seat and in an inverted circular platform shape. A light source concave cavity is fixed at the bottom center of the lens body, and the top surface of the light source concave cavity is an incident free-form surface convex surface and the side of the light source concave cavity is an incident cylinder. The surface of the arc convex surface is evenly provided with light sunburn marks. The top surface of the lens body is evenly fixed with a regular hexagonal bead surface, and the surface of the regular hexagonal bead surface is evenly arranged with sunburn lines, and the side surface of the lens body is a total reflection surface. The structure of the utility model is reasonable. The top surface of the concave cavity of the light source is the convex surface of the incident free-form surface and is provided with light sunburn marks, which can play the role of mixing light and color. The top surface of the concave cavity is a regular hexagonal bead surface and has sunburn marks, so that the light spot color is uniform and the angle is small, and the requirement of small angle is guaranteed under the condition of ensuring mixing light and color, and the applicability is strong and

技术介绍
随着城镇化进程持续进行,尤其是国家在PPP模式上涉及到城市公共照明,旅游景区景观改造以及智慧城市建设等方面上的政策力度还在不断加大,导致景观亮化市场出现井喷式增长。LED灯作为一种新型固态光源,具有发光效率高、节能、环保等优点,建筑照明设计的主流以白光为主,红绿蓝为辅,而用来洗亮建筑的LED投光灯通常采用普通单颗芯片封装的LED,单颗红,绿,蓝LED受其本身的波长限制,不能混出纯白光。第二代的RGBW四合一芯片封装的LED,同样不能混合出纯白光及其他各种色彩纯正的光,为了更好的灯光效果,很多场合的洗墙灯采用多色光源洗墙灯,具有丰富色彩的效果。这样就对透镜的混光混色要求越来越高,而市面上的洗墙灯多采用传统的TIR透镜,通过表面珠面混光混色,存在小角度做不到的问题,导致洗墙高度不够,不能满足场景效果要求。目前RGBW混光混色透镜采用出光面珠面TIR透镜结构,如图1所示,该结构包括入射圆柱面4’、入射弧面2’、全反射面3’及出射面1’。LEDRGBW光源发出光线一 ...
