In some embodiments, optical systems with a reflector and a lens proximate a light output opening of the reflector provide light output with high spatial uniformity and high efficiency. The reflectors are shaped to provide substantially angularly uniform light output and the lens is configured to transform this angularly uniform light output into spatially uniform light output. The light output may be directed into a spatial light modulator, which modulates the light to project an image.

A wall wash recessed light fixture has a light engine assembly has an aperture, an LED module operable to emit light through the aperture, a lens disposed between the LED module and the aperture, and a reflector disposed between the LED module and the lens. The LED module has an optical axis passing through the aperture and substantially parallel to a longitudinal axis (Z). The lens has a first side forming a plano-convex lens with a convex surface facing the LED module and has a second side with a Fresnel lens surface facing the aperture, and the lens is aligned at an oblique angle Θ.sub.1 relative to the optical axis of the LED module. A diffuser is disposed between the lens and the aperture. The plano-convex lens has a principal axis aligned at the oblique angle Θ.sub.1 relative to the optical axis of the LED module.

A wall wash recessed light fixture has an enclosure, an aperture, an LED module, a tubular reflector, a lens, a trim element and a diffuser. The lens is disposed at an opening of the tubular reflector, has a concave surface facing the LED module and a convex surface facing the aperture, and has a principal axis aligned at an oblique angle Θ.sub.1 relative to an optical axis of the LED module. An internal kicker reflector is offset from the optical axis of the LED module toward a second end of the light fixture, and is substantially parallel to a height axis (Z) and lateral axis (X) and faces a center axis of the aperture and. The trim element is disposed below the collimator assembly and at least partially in the opening of the ceiling. A first diffuser covers a first trim opening and is aligned at an oblique angle relative to the longitudinal axis (X).

A space projection lamp includes the convex lens, an uneven reflective plate, motor, light source, integrated main control and power input. The bottom surface of the uneven reflective plate is fixedly connected with the output shaft of the motor. The convex lens and the light source are respectively arranged on both sides of the uneven reflective plate. The light emitted by the light source passes through the convex lens after being reflected by the uneven reflective plate. When the light source irradiates the uneven reflective plate from the side, the reflection is projected out through the imaging of convex lens, forming a layered light effect. When the motor rotates with uneven reflective plate, it will form a multi-level dream light effect.

A recessed lighting apparatus comprising a cap provided with an apex comprising a first opening, adapted to accommodate at least one lighting source, and a second opening, of greater dimensions than the first opening, adapted to emit the light flow emitted from the lighting source. Starting from the interior of the apparatus towards the exterior of the apparatus, the cap can comprise a first cap made of a transparent material acting as a catadioptric reflector and a second cap made of an opaque material which is separated from said first cap by a gap.
