A wall wash luminaire includes a trim assembly that has a trim and a light re-direction assembly. The light re-direction assembly includes a reflector kicker that is configured to re-direct light from the wall wash luminaire and an optical lens that is coupled to the reflector kicker such that the reflector kicker and the optical lens operate as a single unit. The light re-direction assembly is removably coupled to the trim such that the light re-direction assembly is slidingly rotatable with respect to the trim and 360 degrees about a central axis of the trim assembly.

An illumination device including a light source; a light scanner for changing a light path of light-source light; a light diffusion device having element diffusion devices; and a light-path adjustment device disposed on a light path of the light-source light, the light-path adjustment device having element adjustment devices corresponding to respective element diffusion devices, adjusting a light path of the light-source light. An incident position of the light-source light on the light-path adjustment device varies depending on a light path determined by the light scanner. An incident angle of the light-source light on each element diffusion device varies depending on an incident position on the element adjustment device corresponding to the element diffusion device. An emergent angle from each element diffusion device varies depending on the incident angle on the element diffusion device. Each element diffusion device illuminates an element illumination area corresponding to the element diffusion device.

A light source unit includes one or more light source rows that include a first light source row including light emitting devices. The light emitting devices of the first light source rows are arranged at non-uniform intervals. An illuminator includes a light source unit for emitting a bundle of light beams, a first fly-eye lens including lenslets, a second fly-eye lens, and a condenser lens. The light source unit includes one or more light source rows each including light emitting devices. The principal rays of first light beams outputted from a first light source row out of the one or more light source rows enter different lenslets out of the lenslets. A positional relationship between a principal ray of each of the first light beams and the optical axis of the lenslet which the principal ray enters is aperiodic over the first light source row.

An apparatus for intraoral imaging has an intraoral camera that defines a field of view with a first dimension and a second dimension orthogonal to the first dimension. A projector has a laser diode energizable to emit a light beam; a collimator in the path of the emitted light beam; first beam-shaping optics disposed to shape the collimated light beam in the second dimension to form a linear light pattern; focusing optics disposed to focus the shaped collimated beam at a focal plane; and a scanner that is disposed substantially at the focal plane and that is energizable to scan the formed linear light pattern along the second dimension to successive positions of the field of view. A control logic processor coordinates energizing the laser diode and scanner with image capture by the intraoral camera.
