Circuit Arrangement For Electric Light Sources In General
(AREA)
Abstract
Current regulating device for lighting, essentially characterized by being constituted by a capsule that houses an electronic circuit with the possibility of varying, from an external control, the intensity of current passing through the filament of the bulb coupled at one of the ends thereof, to achieve control of the level of lighting and consumption of the former, taking at its other end means of adaptation either to a lampholder, or directly to a conventional support through which electrical conductors pass.
