    • A self-tapping sleeve for providing a ceiling junction for a suspended lighting fixture has a cylindrical body, a center passageway for containing the junction, a thread structure on the perimeter surface of the cylindrical body, and two perimeter cutting elements at the top end of the cylindrical body for producing a circular cutting action in front of the sleeve when the sleeve is rotated in and advance rotation. A trim ring is additionally provided at the bottom end of the body to trim out the ceiling junction when the sleeve is installed. A key-shaped portion of the center passageway receives the key-shaped end of a drive tool used to install the sleeve.
    • 用于为悬挂式照明器具提供天花板接头的自攻式套筒具有圆柱形主体,用于容纳接合部的中心通道,圆柱形主体的周边表面上的螺纹结构和位于圆柱形主体的顶端的两个周边切割元件 该圆柱体用于当套筒旋转并提前旋转时在套筒的前面产生圆形切割动作。 当安装套筒时,在主体的底端处另外设置一个修剪环,以修剪天花板结。 中心通道的键状部分接收用于安装套筒的驱动工具的键形端。

    • A luminaire, such as an indirect linear luminaire, is provided with a floating reflector assembly tied directly to securement points in the luminaire housing. The reflector assembly has a reflector element with tie down openings which overlay the reflector securement points and compliant spring-like retaining clips which overlap the tie down openings and which are secured at their center portion to the underlying securement points by a screw fastener. The width of the retaining clips are narrower than the tie down opening such that the center portion of the retaining clips can be drawn into and contact the housing securement points to provide good electrical grounding. The pressure contact of the retaining clips holds the reflector down yet permits it to float within the housing when the housing is distorted, such as by twisting, thereby avoiding distortion of the reflector.
    • 诸如间接线性灯具的照明设备设置有直接与灯具外壳中的固定点相连的浮动反射器组件。 反射器组件具有一个具有固定开口的反射器元件,该反射器元件覆盖反射器固定点,并且与柔性弹簧状固定夹重叠,该固定夹与绑扎开口重叠,并通过螺钉紧固件固定在其中心部分到下面的固定点。 固定夹的宽度比捆扎开口窄,使得固定夹的中心部分可以被拉入和接触壳体固定点以提供良好的电接地。 保持夹的压力接触件将反射器向下保持,当壳体变形(例如通过扭转)从而避免反射器的变形时,允许其在壳体内浮动。

    • A ballast holder which can be fabricated from a single piece of bent sheet metal material, includes a gusseted riser structure, a base portion extending rearwardly from the foot of the riser structure, and a top flange portion extending in a forwardly direction from the top end of the riser structure for securing one of the mounting flanges of a ballast. The height of the rigid riser structure is chosen to be at least as great as the maximum height of a standard ballast to be held thereby. The ballast holder is used to install a ballast in an inverted position within a lighting fixture housing and can accommodate different sized ballasts. The ballast holder also reduces the amount of structure between the ballast and the overlying reflector element of the lighting fixture and thereby reduces the tendency of the ballast holding structure to bow or distort the lighting fixture's reflector where space is limited.
    • 可以由单片弯曲的金属板材制成的压载支架包括角撑板式立管结构,从立管结构的底部向后延伸的基部以及从顶端向前延伸的顶部凸缘部分 的立管结构,用于固定镇流器的安装法兰之一。 刚性立管结构的高度选择为至少与要保持的标准镇流器的最大高度一样大。 镇流器支架用于在照明器具外壳内的倒置位置安装镇流器,并可容纳不同尺寸的镇流器。 镇流器支架还减少了镇流器与照明器具的上覆反射器元件之间的结构量,从而降低了镇流器保持结构在空间被限制的情况下使照明器具反射器弯曲或变形的趋势。
