ABSTRACT:
This system is characterized in that it comprises a radio remote control, with transmission protocol, and a modulator-receiver decoding the radio signal and modulating the network voltage to thus transmit the information to the light source being installed inside the spotlight, said modulator-receiver thus controlling the illumination being performed by the diodes (LEDs). This system does as well comprise a transformer being apt to power the light sources with 12 Vac, the modulator-receiver being inserted into the primary winding of said transformer. The light sources rectify and filter the secondary voltage, and by means of two auxiliary diodes they recover the information corresponding to the two half-waves, in such a way that the microcontroller can analyze the half-waves thus detecting those having been trimmed in the primary winding; the transmission protocol decoding the commands and thus allowing the microcontroller to operate the diodes (LEDs) according to the command being received.
