Abstract
A headlight incorporates an infrared sensor enabling the light to be turned ON and OFF without physical contact. The system includes a light source and a mechanism for coupling the light source to eyeglass frames or to a headband. A power supply and control unit is disposed remotely from the light source and is interconnected to the light source through an electrical cable. An infrared (IR) motion sensor is interconnected to the power supply and control unit, and electrical circuitry within the power supply and control unit is operative to turn the light source ON and OFF is response to the detection of a hand or other body part by the sensor. In the preferred embodiment, the light source includes a light-emitting diode (LED), and the IR detector is user-adjustable to set the ON/OFF activation distance in accordance with user preferences.
