A light system includes a light source for emitting divergent light, and only one imaging lens arranged in front of the light source in the divergent light for imaging the divergent light directly received from the light source, where the imaging lens is one-piece fabricated part and comprises a first lens section with a non-structured and convex light entry surface curved in a direction of the light source for the entry of the divergent light of the light source into the imaging lens, a second lens section with a convex light exiting surface curved in a light propagation direction for imaging the light entered, and a mask arranged between the first and second lens sections for modifying the light entered into the first lens section before leaving the light exiting surface.

A light fixture assembly includes a light source, a reflector and a shield. The light source emits a beam of light. The reflector directs at least a portion of the beam of light emitted from the light source. The shield is positioned in the reflector to intercept at least a portion of the light emitted from the light source.

A sharpener comprises a cylindrical inner louver portion and a cylindrical outer louver portion each disposed concentrically about an axis that extends forward from a center of a light-emitting surface. Respective back ends of the inner louver portion and the outer louver portion are disposed nearer to the light-emitting surface, and respective front ends and are disposed farther from the light-emitting surface, and the front end of the inner louver portion is disposed nearer to the light-emitting surface than the front end of the outer louver portion is.

A display device includes a panel, a light source, and a display target. The panel has a transparent resin portion and a reflective film formed on a front surface of the transparent resin portion, the display target has a first display layer printed on a front surface of the reflective film and a second display layer printed on a front surface of the first display layer, the first display layer is printed so as to shield the illumination light emitted from the light source, the second display layer is printed in a color different from a color of the first display layer, an outer dimension of the second display layer is smaller than an outer dimension of the first display layer, and a border portion formed by an edge portion of the front surface of the first display layer is provided at an edge portion of the display target.

The examples relate to implementations of an apparatus and a luminaire that use isolated display and lighting portions and optical passages for backlit general illumination through the display. The apparatus includes a general illumination light source, an optical coupling, and an optical array. A luminaire includes the apparatus and a display light board. The display light board may include display light emitters and transparent regions. The transparent regions enable general illumination light to pass through the display light board. The general illumination light source outputs general illumination light that is directed by the optical coupling toward the optical array. The optical array has optical passages and optical array supports. The optical array supports frame the display light emitters and the optical passages channel the directed general illumination light from the optical coupling around display light emitters framed near the optical array supports. Near-field shadow regions are formed under the display light emitters.
