    • A portable lamp including at least one light source and a body having a generally symmetrical bowl-like inner surface and a rim on said inner surface, said rim extending about a central axis that is perpendicular to a plane intersecting said rim, said light source being supported in said body to project a beam away from said inner surface such that the light beam is directed at an angle to the central axis and through said rim of the body, whereby the direction of the beam beyond said rim may be controlled by rotating said body about the central axis and effectively scanning the beam in a cone-like pattern extending outward of said rim. The body is constructed as a suction holding device by having at least the immediate edge of the body surrounding the rim made of a flexible material so the rim can then be pressed against a substantially rigid window pane or the like supported in a window of a structure, to create a negative pressure sufficient to hold the lamp on the pane. The interior surface of the dome-like part of the body may be light reflective to function as a reflector and assisting in directing emitted light.
    • 一种便携式灯,包括至少一个光源和在所述内表面上具有大致对称的碗状内表面和边缘的本体,所述边缘围绕垂直于与所述边缘相交的平面的中心轴线延伸,所述光源为 支撑在所述主体中以将梁远离所述内表面突出,使得所述光束以与所述中心轴线成角度并且穿过所述主体的所述边缘定向,由此可以通过旋转所述边缘来控制所述边缘的方向 本体围绕中心轴线并且以从所述边缘向外延伸的锥形图案有效扫描光束。 通过至少具有围绕由柔性材料制成的边缘的主体的直接边缘,使得该轮体被构造为吸入保持装置,使得该轮缘可以被压靠在支撑在结构的窗口中的基本上刚性的窗玻璃或类似物 ,以产生足以将灯保持在窗格上的负压。 身体的圆顶状部分的内表面可以是光反射的,用作反射器并且有助于引导发射的光。
