    • An adjustable fixture for holding a lamp of the type having a generally annular rim, such as a sealed-beam lamp, includes a lampholder having front and rear generally parallel, spaced generally U-shaped members. The lampholder includes a base section adapted to engage the lamp proximate the rim and a pair of generally straight sections. Spring clips are preferably positioned on the straight sections of at least one of the U-shaped members for biasing the lamp toward the base sections of the U-shaped member. An elongated bridging member extends between the straight sections of the U-shaped members for interconnecting the straight sections. At least one end of the bridging member having a generally flat surface. A support arm member having a surface adapted for engagement with the generally flat surface of the bridging member is removably secured to the bridging arm member. The support arm member is also adapted to be secured to a fixed structure utilizing a fixture mount. Preferably, lamp retaining pins extend inwardly from the base section of the rear U-shaped member. The base section of the front U-shaped member is preferably split to permit the front U-shaped member to be spread for lamp installation.
    • 用于保持具有大致环形边缘的类型的灯(例如密封光束灯)的可调节固定器包括具有前后大致平行且间隔开的大致U形构件的灯座。 灯座包括适于接合靠近边缘的灯的基座部分和一对大致直的部分。 弹簧夹优选地定位在至少一个U形构件的直线部分上,用于将灯朝向U形构件的基部。 细长的桥接构件在U形构件的直的部分之间延伸,用于互连直的部分。 桥接构件的至少一端具有大致平坦的表面。 具有适于与桥接构件的大致平坦表面接合的表面的支撑臂构件可移除地固定到桥接臂构件。 支撑臂构件还适于利用夹具安装件固定到固定结构。 优选地,灯保持销从后U形构件的基部向内延伸。 前U形构件的基部优选地被分开以允许前U形构件扩展用于灯安装。
