The invention relates to a wireless switch for controlling lighting units by infrared signals, depending on some wireless signals received via Internet from a building management center, for switching on or off or adjusting luminosity or by manually actuating the switch. According to the invention, the switch consists of a plastic casing (F), having parallelepipedal shape, where one of the sides is made of glass and represents a keyboard (C) provided with an on/off key (D) and a number of keys (E) for manually adjusting the light intensity of the lighting unit, the keys (D and E) being located on a printed circuit attached onto the back of the glass piece, inside the casing (F), and of an electronic circuit (EIR) for controlling an infrared emitter LED (IR) which may receive commands from the keyboard and/or from an Internet/Ethernet wireless circuit (W) connected to an Internet router, so that the infrared signals transmitted by the LED (IR) are received by a photoresistor (FT) and a receiver circuit (RIR) which transmits, by means of a power circuit (CP), an electric signal for switching on/off or for adjusting light intensity of the lighting unit, the photoresistor (FT), the receiver circuit (RIR) and the power circuit (CP) being connected onto a printed circuit inside the plastic casing which is mounted on the lighting unit. |
