    • An outdoor lighting fixture is disclosed including a first housing containing the fixture ballast or power supply, a second housing enclosing a lamp. Each of the housings is sealed. A support stem joins the two housings and defines a thermal air gap between the two. The only conductive thermal path between the two housings is through the stem and the fasteners engaging the stem and the two housings. In one embodiment, a plurality of tubular spacers are located on elongated screw fasteners define the size of air gap. In another embodiment a single fastener includes washers defining the air gap size. In that embodiment, the fastener may be hollow and acts as a conduit for the electrical leads for the fixture. In another embodiment one closure for a housing includes fins for cooling the fixture.
    • 公开了一种室外照明器具,其包括容纳夹具镇流器或电源的第一壳体,封闭灯的第二壳体。 每个外壳都是密封的。 支撑杆连接两个壳体并且在两者之间限定热空气间隙。 两个壳体之间唯一的传导热路径是穿过杆,并且紧固件与杆和两个壳体接合。 在一个实施例中,多个管状间隔件位于限定气隙大小的细长螺钉紧固件上。 在另一个实施例中,单个紧固件包括限定气隙尺寸的垫圈。 在该实施例中,紧固件可以是中空的并且用作用于固定装置的电引线的导管。 在另一个实施例中,用于壳体的一个封闭件包括用于冷却夹具的翅片。

    • A lamp fixture includes a lamp assembly in a generally cylindrical housing having a radially extending flange at one end. A base for the housing includes mating halves each of which has a flange at one end, these flanges cooperating with the radially extending flange to form a pivot connection between the housing and the base. A pair of contact members of conducting material having arcuate contact surfaces are secured in the pivot connection on opposite sides of the radially extending flange and are connected to electrical terminals in the base. A pair of contact pins connected to the lamp assembly ride on the arcuate contact surfaces throughout any adjustment of the pivot connection. Electrical terminals in the base are fastened to the contact members. Positioned between the mating halves of the base is a wire guide which includes grooves cooperating with grooves in the mating halves to direct conducting wires to the terminals. Electrical conductors are directed to the wire guide either through ports in the side of the base or through a threaded mounting collar on the bottom of the base.
    • 灯具包括在大致圆柱形壳体中的灯组件,其一端具有径向延伸的凸缘。 用于壳体的基座包括配合半部,每个半部在一端具有凸缘,这些凸缘与径向延伸的凸缘协作以在壳体和底座之间形成枢转连接。 具有弓形接触表面的导电材料的一对接触构件固定在径向延伸凸缘的相对侧上的枢转连接中,并连接到基座中的电气端子。 连接到灯组件的一对接触销在枢转连接的任何调节中都骑在弓形接触表面上。 底座中的电气端子固定在接触件上。 位于基座的配合半部之间的是导线器,其包括与配合半部中的沟槽配合的沟槽,以将导线引导到端子。 电导体通过底座侧面的端口或底座底部的螺纹安装环引导到导线器。
