FIELD: electric engineering. ^ SUBSTANCE: contact system of lighting device consists of socket with internal threaded surface, side and central contact and base, made in form of barrel with external threaded surface, with side contact surface, contact washer, isolator and central electrode. Base is made of solid dielectric material, while side contact element of base is made of electro-conductive material, and is inserted into threaded system of base. Contact elements are provided with electric outputs, made of flexible isolated wire, passing in internal section of base. Control elements for light sources are built into internal cavity of cylindrical body. Electronic board with lighting devices is mounted on external surface of body. Aforementioned board is covered by transparent disperser. ^ EFFECT: simplification and increased reliability of contact system of lighting device, increased precision and decreased costs. ^ 8 cl, 8 dwg |
