1. An electromagnetic Christmas tree light comprising:

  • radio frequency oscillator means, receivable of a DC electric current and responsive to a modulation signal, for providing a modulated radio frequency current;

    radio frequency modulator means, receivable of a DC electric current and operatively connected to said radio frequency oscillator, for producing a modulation signal, said radio frequency modulator means containing a plurality of selectively activatable modulation control circuits, each of said modulation control circuits producing a respective modulation control signal;

    radio frequency amplifier means, receivable of a DC electric current and operatively connected to said radio frequency oscillator means, for producing an amplified modulated radio frequency current;

    antenna means, receivable of an amplified modulated radio frequency current, for propagating an electromagnetic field, said antenna means comprising at least one array, said array comprising odd elements and even elements, said array including means for alternating polarity of said odd elements and said even elements, to propagate said electromagnetic field between said odd elements and said even elements, said antenna means further comprising distribution means for distributing said amplified modulated radio frequency current to said at least one array such that juxtaposed arrays alternate in polarity and said electromagnetic field is substantially contained within said antenna;

    coupling means, operatively connecting said radio frequency amplifier means and said antenna means, for maximizing power transfer from said radio frequency amplifier means to said antenna means;

    power supply means, receivable of an AC electric current, for rectifying and converting a AC electric current into a DC electric current, said power supply means operatively connected to said radio frequency oscillator means, said radio frequency modulator means and said radio frequency amplifier means;

    switching means for electrically connecting said power supply means with an external AC power source, said switching means comprising at least one magnetically-closeable, normally open switch, latching means for latching said switch into a closed position when said switch is magnetically closed and deactivation means for unlatching said switch when closed, said at least one magnetically-closeable, normally open switch being closeable upon positioning of a magnetic object proximate said at least one magnetically-closeable, normally open switch;

    timing means, operatively connected to said radio frequency modulator means and said power supply means, for selectively activating one of said plurality of selectively activatable modulation control circuits, said timing means including sensing for detecting the amount of time a magnetic object is proximate said at least one magnetically-closeable, normally open switch, said timing means selecting said one of said plurality of selectively activatable modulation control circuits to be activated in response to the amount of time said magnetic object is proximate said at least one magnetically-closeable normally open switch.
