Langley made 166 league appearances in three-and-a-half years at the Seagulls, including two seasons as captain.
He then played 323 times for Fulham in nearly a decade at Craven Cottage, before joining QPR, playing in their League Cup-winning side in 1967.
The funeral will take place at Breakspear Crematorium in Ruislip on Friday, 21 December at 1415 GMT, followed by a wake at Hillingdon Borough FC - a club he managed after retiring as a player.
Langley's son Peter told Brighton's website that anyone is welcome to attend either event.
