    • A light assembly is provided for illuminating a worksurface below and in front of the light assembly. The light assembly includes a housing configured for mounting over the worksurface below an overhead cabinet or shelf, and an elongated linear light source such as a fluorescent light bulb supported in the housing. A step reflector is supported by the housing for reflecting light generated by the light source onto the worksurface therebelow, and a tubular lens is mounted telescopically onto the light source. The tubular lens includes prism-shaped triangular rings on its inside surface for controlling the light from the light source onto the worksurface therebelow. The tubular lens includes end sections and intermediate sections that can be selectively assembled together to cover the light source. By selectively including zero, one, or more of the intermediate sections, a variety of different length linear light sources can be covered.
    • 提供一个灯组件,用于照亮灯组件下方和前面的工作表面。 灯组件包括被配置用于安装在架空机架或架子下面的工作表面上的壳体,以及支撑在壳体中的细长线性光源,例如荧光灯泡。 台阶反射器由壳体支撑,用于将由光源产生的光反射到其上的工作表面上,并且管状透镜可伸缩地安装在光源上。 管状透镜在其内表面上包括棱柱形三角形环,用于将来自光源的光控制到其下方的工作表面上。 管状透镜包括能够选择性地组装在一起以覆盖光源的端部部分和中间部分。 通过选择性地包括零个,一个或多个中间部分,可以覆盖各种不同长度的线性光源。

    • A reflector includes multiple segments that can be interconnected by a flexible extrusion and connected to a top collar to form a reflective shell around a light source. The segments are corrugated for increased strength, the corrugations forming elongate facets characterized by reflective surfaces that reflect light laterally beside the light source as well as downwardly from the light source to minimize light reflected back toward the light source and maximize the service life of the light source. The corrugations add strength and stability to the segments permitting the sheet thickness, overall reflector weight, and cost to be minimized. The segments are preferably formed from a stamped aluminum sheet of about 0.020 inch thickness, and can be pre-or-post anodized to form the reflective surfaces, the pre-anodized surfaces being protected by a polycoat during stamping. Differently shaped segments can be arranged as desired to achieve a desired pattern of reflected light, and differently shaped top collars can be used to adapt the reflector for use on different light sources. The reflector can be shipped in a knocked-down state to minimize space required for shipping or storage, and assembled or repaired on site.
    • 反射器包括多个段,其可以通过柔性挤出物相互连接并连接到顶部环以在光源周围形成反射壳。 这些节段是波纹状的以增加强度,波纹形成细长面,其特征在于反光表面,其反射光源横向在光源旁边,以及从光源向下反射,以将光反射回光源并使光线的使用寿命最大化 资源。 波纹增加了片段的强度和稳定性,允许片材厚度,整体反射器重量和成本最小化。 这些段优选由约0.020英寸厚度的冲压铝板形成,并且可以被阳极氧化处理或后阳极化以形成反射表面,预阳极氧化表面在冲压期间被聚酰胺保护。 可以根据需要布置不同形状的片段以实现期望的反射光图案,并且可以使用不同形状的顶部套环来使反射器适用于不同的光源。 反射器可以以倒装状态运输,以尽量减少运输或存储所需的空间,并在现场组装或维修。
