Abstract

Embodiments of the invention are directed to wall recessed two-component luminaires. The two components can include a primary optical subsystem and a secondary optical subsystem. The primary optical subsystem can provide indirect lighting, illuminate an architectural space upward toward a ceiling, and/or have greater luminous flux than the secondary optical subsystem. The secondary optical subsystem can provide direct lighting, illuminate an architectural space horizontally and/or downward, provide lit appearance, provide direct view color and/or color gradients, provide direct view luminance and/or luminous gradients, and/or provide lighting for ambience.
