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, 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.
