Lighting fixture with an integrated mechanical fixing and electrical connection system

An integrated mechanical fixing and electrical connection system, comprising:

• a junction box and a lighting fixture, wherein said junction box includes a first electrical connector for electrically connecting said lighting fixture to the mains power supply of a system,
• a coupling mechanism and a second electrical connector for fixing and electrically connecting said lighting fixture to said junction box, and
• a compartment adapted to house accessories of the lighting fixture and an inner space available to an installer for the wiring of said electrical system which passes in correspondence of fittings placed laterally to and/or at the bottom of said junction box,
• wherein said first electrical connector is a multipolar electrical connector,
• wherein said lighting fixture includes a series of lenses and/or LEDs on said light emission surface, which are placed so that a reflecting portion of said light emitting surface includes one or more string of LEDs and that each set of LEDs of a string is coupled with a specific type of optical lens, wherein said optical lenses are designed to create a concentrated beam of light, a widened beam of light and an elliptical beam of light,
• wherein said lighting fixture includes an electronic control circuit comprising a first microprocessor, which is connected to a block containing a power supply unit, a battery charger and presence sensors of the electrical network and which is configured to manage the operation of said lighting fixture and the charge of a main battery of said lighting fixture and of an auxiliary battery placed inside said compartment of said junction box, said auxiliary battery being connected to said second electrical connector for the connection to said lighting fixture and said first microprocessor being connected to a serial interface for communicating with said junction box and being adapted to regulate, by means of a plurality of respective current regulators, the current driving intensity of each string of LEDs.
