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.

Claims

1. A swimming pool spotlight lighting system comprising:

a radio remote control, with transmission protocol; and

a modulator-receiver installed in a primary winding of a transformer, wherein said modulator-receiver receives radio transmitted commands transmitted by said remote control and passing said commands to LED light sources installed inside the spotlight;

wherein said commands corresponding to two half-waves is recovered with two auxiliary diodes, in such a way that a microcontroller can analyze the half-waves thus detecting the half-waves that have been trimmed in the primary winding; and

wherein the transmission protocol being operable to transform the bits composing said commands into a sequence of labeled half-waves, and thus being apt to transmit commands needed for the operation of LEDs; and

wherein said LEDs are operated by said microcontroller based upon said transmitted commands.

2. A swimming pool spotlight lighting system as per claim 1, wherein it comprises the transformer being apt to power the light sources with 12 Vac, the modulator-receiver being inserted into the primary winding of said transformer, the secondary voltage being rectified and filtered in order to thus obtain a direct current supply.

3. A swimming pool spotlight lighting system as per claim 1, wherein the LEDs are white.

4. A swimming pool spotlight lighting system as per claim 1, wherein the LEDs are of different colors.

5. A swimming pool spotlight lighting system as per claim 4, wherein each of the colors of the LEDs is controlled with a dedicated circuit consisting in a microcontroller output and a transistor generating a voltage determining the maximum current being generated by the power circuits.

6. A swimming pool spotlight lighting system as per claim 4, wherein a pulse-width modulation system allows to regulate the light intensity for each color of the LEDs.

7. A swimming pool spotlight lighting system as per claim 4, wherein the composition of each of the composite colors of the LEDs is determined by three percentages of width-modulated pulses, said percentages being stored in the memory of the microcontroller.
