LIGHTING SYSTEM "LIGHT SPHERE-UMBRELLA" Russian patent published in 2009 - IPC F21L14/00 

FIELD: instrument engineering.

SUBSTANCE: lighting system "Light Sphere - Umbrella" comprises a base represented with expanded legs, a telescopic tripod mounted on a base, lateral strainers provided with fasteners to earth. Besides, it embodies an electronic control unit with a push-button control panel, cable connected to a light source mounted on a rotary joint within upper part of the telescopic tripod. The light source presents a closed shell with an enclosed caged frame comprising a lower alignment flange with cooling holes, connected to a reflective plate, with a lamp bracket. And the caged frame prevents contact of the shell and lamp. An aligning bar goes throughout the height of the shell and extends upwards outside of the shell through the specified upper hole wherein in upper part there is a restraint plate inside of the shell. In lower part of the light source, outside of the shell, there is a lower ring plate joint by means of fastener with the lower alignment flange, so the lower part of the shell is spaced between the ring plate and the lower alignment flange. The shell consists of two interconnected parts and represents a lampshade mounted on umbrella-shaped spokes pivoted over the frame via adapters on the upper restraint plate and the lower alignment flange. The aligning bar is clamped on the reflective plate from below by means of a sleeve coupling. In the upper part of the aligning bar, there is an arrester sleeve freely-moving over the shell. Its extreme lower position provides a required volume for the umbrella-shaped spokes. The upper part of shell is fastened between the restraint plate and the upper ring plate placed over the shell with said plates connected by fasteners.

EFFECT: cost reduction and higher speed of the system.
