ABSTRACT:
An illuminated collar. The illuminated collar includes a collar for placement on an animal, at least one light emitting diode placed on the outer exterior of the collar to be visible when the collar is worn, a motion sensitive switch designed to respond to the motion of the animal an on/off switch to selectively turn on or off battery power to the circuit, a battery, a timing circuit, and a low battery power detection circuit. The light emitting diodes, motion sensitive switch, on/off switch, battery, timing circuit and low battery detection circuit are connected together. The timing circuit is triggered by the open and close state of the motion sensitive switch which extinguishes illumination of the light emitting diodes after a predetermined duration, to thereby prevent constant and re-illumination of the light emitting diodes before the motion sensitive switch can change state from open to close again. An intermittent flashing of the light emitting diodes will thus be established for constant movement. The low battery detection circuit will sound an audible alarm to warn the user of a low battery. This feature is especially helpful for the visually impaired, when the device is used on seeing on dog collars.
