Abstract: A luminous turning button for an electric circuit, including a handle mounted to pivot about an axis to actuate at least one electric switch unit and that is illuminated by a light source substantially disposed along the axis. The handle includes a cap forming a disk and a gripping tab that protrudes in a diametral plane. The cap is made of translucent or transparent material capable of allowing the light to travel to the outside, the gripping tab being hollow and covering an integrated mechanical base made of opaque material.

Abstract: A luminous turning button for an electric circuit, comprising a handle (20) that is mounted so as to pivot about an axis (X) to actuate at least one electric switch unit (12) and is illuminated by a light source (S) substantially disposed along the axis (X), the handle (20) comprising a cap (22) forming a disk (22B) and a gripping tab (22A) that protrudes in a diametral plane, characterized in that the cap (21) is made of translucent or transparent. material capable of allowing the light to travel to the outside, the gripping tab (22A) being hollow and that it covers an integrated mechanical base (21) made of opaque and mechanically strong material.

Abstract: The lighting device comprises at least one emitter (10) of white light (9) produced by an initial radiation (1) and a secondary radiation (2), an electronic control circuit (11) to control the lighting, and a communication circuit (12). The electronic circuit (11) controls power supply of the light emitter to emit a modulating light signal (3, 4, 31, 36) of said initial radiation according to a communication signal (13). Said modulating light signal is designed to be received by a light signal receiver (18) sensitive to the initial radiation (1). A lighting installation comprises a power supply line, at least one lighting device (8) and at least one electrical apparatus (95, 96) connected to a receiver (18) comprising a sensor (19) sensitive to the initial radiation (1).

Abstract: The marking device comprises a light source and a processing circuit to control lighting of said light source. Said device comprises an optic communication having at least one optic emitter and/or one optic receiver connected to the processing circuit. A detector detects the presence, movement or passage of an object. Said detector is connected to the processing circuit to control the optic communication according to signals supplied by said detector. A marking installation comprises marking devices arranged for example on a section of runway for an airport for guiding aircraft, or on a section of road to perform road signalling. The marking process enables the marking devices to be switched on by optic means according to detections.
