    Abstract: Illumination articles are described. More specifically, illumination articles that include a wearable device configured for wearing on the head of a wearer, a lightguide and light sources for emitting light into the lightguide are described. The illumination articles allow for wearable devices that uniformly illuminate a working area at high brightness without providing excessive glare to observers. The disclosed illumination article comprises: a wearable device configured for wearing on the head of a wearer, a lightguide disposed on the wearable device, wherein the lightguide is elongated and has a first end and a second end opposite the first end, and a first light source positioned at the first end, for emitting light into the lightguide. The lightguide further comprises a light emitting surface extending generally in an x-direction between the first and second end, and a light reflecting surface positioned opposite to the light emitting surface, wherein the light reflecting surface comprises a plurality of light extractors configured for directing light in a y-direction perpendicular to the x-direction, and wherein the light emitting surface is configured for directing light into an xy-plane.

    Abstract translation: 描述照明物品。 更具体地说，描述了包括被配置为佩戴在佩戴者的头部上的可穿戴装置，用于将光发射到光导中的光导和光源的照明制品。 照明制品允许以高亮度均匀照明工作区域的可穿戴装置，而不向观察者提供过度的眩光。 所公开的照明制品包括：佩戴在穿戴者的头部上的佩戴装置，设置在佩戴装置上的光导，其中光导细长并具有与第一端相对的第一端和第二端，以及第一光 源位于第一端，用于将光发射到光导中。 该光导还包括大致在第一和第二端之间沿x方向延伸的发光表面和与发光表面相对定位的光反射表面，其中光反射表面包括多个光提取器，其被配置用于引导光 在垂直于x方向的y方向上，并且其中所述发光表面被配置为将光引导到xy平面中。
