We propose an improved method to design freeform reflectors for architectural lighting: one accent lighting and another large area wall washing. The designed effectively distribute light fluxes over the target surfaces, generate appropriate illumination patterns comfortable visual environments, which provides greater flexibility designs, allows many challenging improves energy-efficiency simultaneously.
