Light-emitting diode UV LEDs for sterilization. LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available. The progressive miniaturization of low-voltage lighting technology, such as LEDs and
LED Incapacitator LED Incapacitator The Light Emitting Diode (LED) Incapacitator is a weapon designed like a flashlight. It emits an extremely bright, rapid, and well-focused series of 'differently-colored random pulses.' Before the human eyes can focus in on one frequency, another frequency comes on, causing intracranial pressure, which results in headaches, nausea, vomiting, disorientation, irritability, and visual impairment to the target (opponent). The non-lethal weapon is intended as a means of protection by law enforcement officials such as police and border patrols. The light emitted is capable of rendering opponents temporarily blind so that they can be subdued more easily. According to
