Description

CECOM is seeking sources of supply for the Light Emitting Diode Array, Part of Forward Looking Infrared Systems, Thermal Imaging Night Vision. The light emitting diode array (infrared) performs the function of converting detected and amplified infrared radiation to visible light. This conversion is accomplished by the LED array which is comprised of one multi-element light emitting diode array integrated with a set of system connectors. The drive signals applied to the LED array are normalized by internally packaged resistors which provides a normalized signal input to the LED array. These resistor bias packs will need to be laser trimmed to assure uniform illumination across the array. This permits the LED array to supply constant contrasting visible displays. The visible display emitted by the LED array varies in direct correspondence with the input drive signals supplied by the externally connecting modular system electronics. The light emitting diode is a solid state quantum light emitter rather than a thermal or plasma light source. A diode chip of gallium arsenide phosphide will emit light when the diode is injected with a forward bias of current which builds up a voltage knee of approximately 1.4 volts. Light output increases with current in a linear fashion where the diode is biased above the knee voltage. Interested suppliers must provide information on their experiences with similar items.
