Abstract: An LED lamp for outdoor and large space lighting, particularly for streets, warehouses car parks and the like, is adapted for fitting into legacy light fittings designed for sodium bulbs and the like. The LED lamp includes light emitting diodes arranged over a surface of the lamp, is rotatably connected through a rotatable electrical connection to a screw-in adaptor for insertion into a legacy screw-in socket, such that the screw in adaptor is rotatable independently of the lamp, so that the legacy screw in socket can be used even though the light fitting is too small to allow rotation of the LED lamp. Additional variants provide for cooling airflow through the light fitting, for temperature control of the LEDs, and for failure protection, to ensure a longest possible lamp lifetime.

Abstract: An apparatus for facilitating a controlled descent of a body is disclosed. The apparatus includes a rotatable reel around which a portion of a cable is wound, a first end of the cable secured to the reel and a second end of the cable free; a friction drum around which a portion of the cable, is wound; a carrier on which the reel and the drum are mounted, a braking mechanism for braking rotational motion of the reel and for balancing descending speed of the body; a harness, for harnessing the device to the body; and a damping mechanism for damping the initial impact.
