In you favourite language implement the following.

Do forever

    Adjust Vlimit here if desired (or almost anywhere else)

    For Vcount = 1 to Vcountmax ' Vcount steps once each loop
                                                        ' and resets 
when max reached

        if count <= Vlimit then
            turn LED on
        else
            turn LED off
        endif

        Optional delay

    Next

Loop

LED will be lit for the ratio Vlimit/Vcountmax
Increasing Vlimit increases on time.
The "For" loop can be accessed once per timer tick or after a delay or 
just run flat out. If running flat out there will be some "dead time" 
while the code outside the For/Next loop is run.
