Light-emitting diode emitted, so the attainment of high efficiency in blue LEDs was quickly followed by the development of the first white LED. In this device a :Ce (known as "YAG") cerium doped phosphor coating on the emitter absorbs some of the blue emission and produces yellow light through fluorescence. The combination of that yellow with remaining blue light appears white to the eye. However, using different phosphors (fluorescent materials) it also became possible to instead produce green and red light through fluorescence. The resulting mixture of red, green and blue is not only perceived by humans as white light but is
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
