An electronic display for amusement or ornamentation includes a CMOS counter chip connected to a low voltage DC source, with each counter output connected directly to one of a plurality of LEDs. An antenna wire, which can be a short length of wire or a wire hook is connected directly to the trigger input of the chip, and the ambient field-induced AC voltage on the antenna is sufficient to actuate the counter chip and cause the LEDs to flicker sequentially as the counter outputs are incremented. The LEDs may be embodied in a wide variety of decorative arrays to represent objects, images, and icons. The visual effect is not monotonous, due to the natural variations of the ambient field about the ornament. The invention also comprises a Christmas tree light assembly, including a plurality of ornaments, each constructed as described and including a hook-shaped antenna wire for hanging on a Christmas tree. Each ornament may be powered by an individual battery included therein. Alternatively, the invention provides a transformer/rectifier power supply with an input connected to utility power and 3-9 VDC output connected to a cable which is hung about the Christmas tree. Each ornament may be wired or plug-connected to the cable, and the individual batteries for each ornament may be eliminated. The antennae of the ornaments may be triggered by ambient electromagnetic fields; alternatively, the power cable may be provided with a trigger wire that carries a low voltage, induction-coupled signal trigger signal to all the ornaments.
An electronic display for amusement and ornamentation, including a plurality of LEDs, an integrated circuit counter device including a trigger input having a high signal sensitivity, a DC power supply connected to said integrated circuit counter device, said integrated circuit counter device having a plurality of sequentially activated outputs, each of said integrated circuit outputs connected directly to one of said plurality of LEDs, an antenna conductor means connected directly to said trigger input of said integrated circuit counter device and disposed to receive ambient electromagnetic fields in the vicinity of said display and to generate a corresponding AC signal to actuate said trigger input of said integrated circuit counter device, said antenna conductor means comprising a hook secured to said display for suspending said display from an object.
An electronic display for amusement and ornamentation, including first and second pluralities of LEDs, first and second integrated circuit counter devices, each including a trigger input having a high signal sensitivity, a DC power supply connected to each integrated circuit counter device, each integrated circuit counter device having a plurality of sequentially activated outputs, each of said sequentially activated outputs of said first integrated circuit connected directly to one of said first plurality of LEDs, each of said sequentially activated outputs of said second integrated circuit connected directly to one of said second plurality of LEDs, antenna conductor means connected directly to said trigger input of said first integrated circuit counter device and disposed to receive ambient electromagnetic fields in the vicinity of said display and to generate a corresponding AC signal to actuate said trigger input of said first integrated circuit counter device, said first integrated circuit counting device including a cascade output, and said second integrated circuit device including a trigger input connected to said cascade output of said first integrated circuit device, whereby said second integrated circuit counter device counts at a rate that is an integral divisor of the counting rate of said first integrated circuit counter device.
A combination light display, including a plurality of LEDs, an integrated circuit counter device including a trigger input having a high signal sensitivity, a DC power supply connected to said integrated circuit counter device, said integrated circuit counter device having a plurality of sequentially activated outputs, each of said integrated circuit outputs connected directly to one of said plurality of LEDs, antenna conductor means connected directly to said trigger input of said integrated circuit counter device and disposed to receive ambient electromagnetic fields in the vicinity of said display and to generate a corresponding AC signal to actuate said trigger input of said integrated circuit counter device and operate said LEDs in a serially-actuated, flickering mode.
