    • A spotlight is provided that employs stationary motors for positioning a light beam at a desired azimuth and elevation such that there is no blind spots of the light beam at the zenith of the azimuth and elevation. A drive train rotates the spotlight about a horizontal axis and allows the motor driving the rotation to have a stationary mounting in a base while at the same time providing the light beam of the spotlight with a range of elevation that exceeds 90 degrees from a horizontal reference plane at any desired azimuth. More particularly, a stationary motor drives a capstan, which includes a spool that winds and unwinds a cable connected to a lamp assembly of the spotlight for positioning the light beam at a desired elevation. The cable is communicated between the lamp assembly and the capstan by way of a central bore in a mast that supports the lamp assembly for rotation about a vertical axis.
    • 提供了一种聚光灯,其采用固定电动机将光束定位在所需的方位角和高度,使得在方位角和高度的顶点处没有光束的盲点。 传动系围绕水平轴旋转聚光灯,并允许电动机驱动旋转以在基座中具有固定安装,同时为聚光灯提供与水平参考值超过90度的仰角范围 在任何所需的方位平面。 更具体地说,固定马达驱动绞盘,绞盘包括一个线轴,其卷绕和展开连接到聚光灯的灯组件的电缆,以将光束定位在期望的高度。 电缆通过桅杆中的中心孔在灯组件和绞盘之间连通,该桅杆支撑灯组件以围绕垂直轴线旋转。
