A luminaire system is provided that has directional light projection optics combined with a light distribution modifier to produce a non-uniform angular light intensity distribution from a single or array of light sources. The luminaire system provides for light intensity distribution with directional asymmetry meeting the specifications and requirements of aviation obstruction lights. The light distribution modifier component or subassembly redirects, scatters, refracts, diffracts and/or blocks part of the projection light in the distribution of the primary optics that would otherwise produce ground scatter. Unlike peripheral light shields at the marginal limits of the light distribution from the luminaire light system, the light distribution modifier is located near to the optical axis of the projection optics system.

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.

A lighting module has an LED (44), a lens (45) over the LED to produce a beam-shaped output from the LED and a collimator (50) arranged to partially collimate the beam-shaped out-put. Blue light is provided at large angles to the normal, for example using a filter arrangement (54, 56) over the collimator which is adapted to filter light from the collimator at relatively large angles to the normal. The filter arrangement does not filter light from the collimator at relatively small angles to the normal. Thus, the module provides white task light in a normal direction and blue ambient light at steep angles. The overall system can be compact and light efficient.

The invention provides a lighting unit (1000) comprising a lighting device (100), wherein the lighting device (100) comprises a light source (10) configured to provide light source light (11) and beam shaping optics (20) configured to shape the light source light into a lighting device beam (101), wherein the lighting device (100) comprises a window (30) comprising an upstream face (31) directed to the light source (10) and a downstream face (32), wherein the lighting unit (1000) further comprises a beam modifier (200) configured adjacent to the window (30) and configured to intercept at least part of said lighting device beam (101), wherein the lighting device (100) and the beam modifier (200) are configured to modify said lighting device beam (101) to provide a lighting unit beam (1001) downstream from said beam modifier (200), wherein the beam modifier (200) comprises a printed beam modifying element (210).

A lighting device includes a light source and first and second reflection surfaces. The first reflection surface reflects source light from the light source, and projects first light on first and second regions on an illuminated surface. The second region is closer to the lighting device than the first region. The second reflection surface is tinted in a prescribed color, and reflects secondary and higher-order reflection light of the source light, and projects second light on the second region. An absolute value of a difference between correlated color temperatures of the first light projected on the first region and of mixed light of the first and second lights projected on the second region is smaller than an absolute value of a difference between correlated color temperatures of the first light projected on the first region and of the first light projected on the second region.

A system of modular multi-aperture reflector sheets for use in general and specialty luminaires is disclosed. These sheets, designed to be simple in design, manufacture, and installation, allows for enhancing, adjusting, varying, or correction of the light distribution provided by luminaires during production or deployment. The reflector sheets are made of highly-reflective, thin material and feature multiple apertures that are patterned to redirect the light output emerging from the output of a luminaire. The reflector sheets are intended to be used in combination with both standard and custom reflectors and replace complicated and expensive lenses and optics that are often deployed to modify luminaire light distribution. The sheets are modular and can be replaced easily, allowing for standard luminaires having multiple possible light distribution patterns without further complication. Also, custom multi-aperture reflector sheets can be designed, shipped, and installed easily if further modification or correction of the light distribution is desired.
