    • An infrared motion sensing apparatus mounted within the canopy of a decorative lighting fixture where the apparatus may be vertically adjusted. The apparatus comprises a pyroelectric infrared sensor located in a stationary base. Mounted over the sensor and movable in a vertical direction is a Fresnel lens array. The array is mounted to a frame that is constrained to ride on the base in a vertical direction in response to the rotation of a screw. The canopy has an opening to allow radiation to be received by the sensor and a second opening for a stem of the screw so that manipulation of the stem may take place without disassembly of any part of the lighting fixture.
    • 安装在装饰照明器具的顶盖内的红外线运动感测装置,其中该装置可以垂直调节。 该装置包括位于固定基座中的热电红外传感器。 安装在传感器上并在垂直方向上可移动的是菲涅尔透镜阵列。 该阵列安装到框架上,该框架被限制为响应于螺钉的旋转而在垂直方向上骑在基座上。 盖子具有开口以允许辐射被传感器接收,并且第二开口用于螺杆的杆,使得杆的操纵可以在不拆卸照明器具的任何部分的情况下进行。
