    • 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。

    • A portable pocket light, comprising three sections; (1) a main body containing an electric circuitry board, battery compartment, and a power switch; (2) a lamp section containing a light source, a lens, and a means for rotatably attaching said lamp section to the main body and facilitating rotation of said lamp section in a 300 degree arc about the an extended axis of said main body, and (3) a sheath section comprising two prongs, and an axial means for rotating said main body an unimpaired 360 degrees within the confines of the two sheath prongs. The two prongs further facilitate a self-standing base by means of which the pocket light may rest on a surface and provide stable, adjustably aimed illumination in a plurality of directions and orientations. The pocket light is fabricated with an integral spring-loaded clip which enables temporary attachment of the pocket light to the brim of a wearer's cap, a shirt pocket, or other stable object. Overall, the disclosed pocket light provides low power consumption, and adequately bright light in either a hands-free or a handheld application.
    • 便携式口袋灯,包括三个部分; (1)包含电路板,电池仓和电源开关的主体; (2)包含光源的灯部分,透镜和用于将所述灯部分可旋转地附接到主体并且便于围绕所述主体的延伸轴线以300度电弧旋转所述灯部分的装置,以及 (3)包括两个插脚的护套部分和用于使所述主体在两个护耳尖的范围内旋转360度的轴向装置。 两个插脚进一步促进了一个自立式底座,通过该底座,口袋灯可以搁置在表面上,并且在多个方向和取向上提供稳定的,可调节的瞄准照明。 口袋灯由一体的弹簧夹制成,其能够将口袋灯临时附接到佩戴者的帽子,衬衫口袋或其他稳定物体的边缘。 总之,所公开的口袋灯在免提或手持应用中提供低功耗和足够亮的光。
