Aircraft Escape Slide Lighting System with Self-Regulated, Circuit-Protected Luminaires

Embodiments include computing devices, apparatus, and methods implemented by the apparatus for constant current regulation for luminaires of an aircraft escapes slide lighting system. In various embodiments, a power source may be electrically connectable to a luminaire. The power source may be regulated, unregulated, rechargeable, and/or non-rechargeable. Each of a plurality of constant current regulator circuits may be integral to a luminaire having at least one LED. Each of the constant current regulator circuits may be electrically connected in parallel to a power source. A protection circuit may be configured to provide power surge and/or reverse polarity protection to the constant current regulator circuits as a centralized protection circuit, or a decentralized plurality of protection circuits, each corresponding to a constant current regulator circuit. Testing of the escapes slide lighting system having the constant current regulator circuits may provide an unambiguous indication of whether any of the luminaires are inoperative.
