具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是,此处所描述的具体实施例仅仅用于解释本发明,而非对本发明的限定。另外还需要说明的是,为了便于描述,附图中仅示出了与本发明相关的部分而非全部结构。
图1为本发明实施例提供的一种可切换颜色的光源的结构示意图,图2为本发明实施例提供的一种可切换颜色的光源出射第一颜色光时的示意图,图3为本发明实施例提供的一种可切换颜色的光源出射第二颜色光时的示意图,如图1-3所示,本发明实施例提供的可切换颜色的光源包括:
光源10,光源10用于出射光束。
滤光装置11,滤光装置11位于光束的传播路径上。
其中,光源10包括第一颜色光源101和第二颜色光源102,第一颜色光源101用于出射第一颜色光21,第二颜色光源102用于出射第二颜色光22。滤光装置11包括第一滤光区域111和第二滤光区域112,第一滤光区域111用于通过第一颜色光21,第二滤光区域112用于通过第二颜色光22,第一颜色光21和第二颜色光22为互补色光。

如图2所示,当可切换颜色的光源发第一颜色光21时,第一颜色光源101开启,第二颜色光源102关闭,由于第一颜色光21和第二颜色光22为互补色光,第一颜色光21完全不能通过第二滤光区域112,此时,第一颜色光21仅从第一滤光区域111出射,从而实现第一滤光区域111发出第一颜色光21,且发光区域的边界锐利、亮度均匀。同理,当可切换颜色的光源发第二颜色光22时,第二颜色光源102开启,第一颜色光源101关闭,由于第一颜色光21和第二颜色光22为互补色光,第二颜色光22完全不能通过第一滤光区域111,此时,第二颜色光22仅从第二滤光区域112出射,从而实现第二滤光区域112发出第二颜色光22,且发光区域的边界锐利、亮度均匀。同时,该可切换颜色的光源无需加入物理阻隔,使得第一滤光区域111和第二滤光区域112的边界是连续的,从而使得可切换颜色的光源在用于工件检测时,可切换颜色的光源对应的物料区域均能受到光照,降低漏检的风险。

可选的,透射基板41包括光漫射板或者透明基板。
其中,光漫射板可以由透明的基体材料和分散在基体材料内的多个粒子构成,分散在基体材料内的粒子由于相对于可见光区域的波长的光折射率与基体材料不同,使得入射到光漫射板上的光产生漫透射,通过设置透射基板41采用光漫射板,可使得可切换颜色的光源发光亮度均匀。
在其他实施例中,透射基板41也可采用透明基板,以降低对光线的衰减,提高光线利用率,从而提高可切换颜色的光源的照明亮度。
