A lighting assembly includes a light guide having opposed major surfaces, a light input edge extending between the major surfaces and including first and second input regions, a first light guide region associated with the first input region and including first light extracting elements, and a second light guide region associated with the second input region and including second light extracting elements. A first light source segment is arranged to input light through the first input region and into the first light guide region, and a second light source segment is arranged to input light through the second input region and into the second light guide region. The first light source segment and the second light source segment are independently controllable to control an illumination state of the solid-state light emitters

The present disclosure is an improvement in bi-focus lenses. The disclosure relates to the use of multiple channels of LED/Lens combinations to achieve a smooth and continuous range of emitted beam angles of light in a wider range of beam angles than previously possible through only two channels of LED/Lens combinations. The resultant product will produce a continuous range of beam angles in a range exceeding 35 degrees from narrowest bean angle to widest beam angle. The lens channels selected are weighted so as to maximize the contribution of a single channel lens to the overall beam projection.

Example embodiments provide lighting fixture mounting kits for mounting a flat panel lighting fixture to a mounting surface. One mounting kit comprises a mounting frame and a lighting fixture. When the mounting frame is secured to the mounting surface, a junction box is accessible therethrough. The mounting frame and lighting fixture are shaped for engagement and attachment to one another. Another mounting kit comprises a mounting plate and a lighting fixture. The mounting plate may comprise indexing tabs for alignment with corresponding indexing slots of the lighting fixture and extending outwardly from a plate portion of the mounting plate. The lighting fixture may comprise a back portion having therein one or more indexing slots for receiving an indexing tab therein. Insertion of the indexing tab into the indexing slot guides the engagement of the lighting fixture with the mounting plate.

A lighting device including: a source emitting a light cone; an electronic control circuit; a wall defining an enclosure including a first area through which the light cone passes, and a second area complementary to the first area; and a diffuser directing part of the light by backscattering towards the second area. The diffuser includes a first part oriented perpendicular to the axis of revolution of the light cone and forming a first divergent lens, and a second part forming a second divergent lens having a shape of a flared truncated cone with its axis of revolution parallel to the axis of revolution of the light cone, in which a larger diameter end is closest to the light source and a smaller diameter end is adjacent to the first part and surrounds the first part.

The present invention discloses a display structure comprising at least one display module, wherein the display structure comprises at least one substrate layer comprising polymer, glass, ceramic or composite materials and integrated electrically conductive circuitry with electronics, where applicable, and light emitting devices; at least one electrically conductive layer, enabling intelligent control of the light emitting devices; wherein a display module comprises at least one coating or molded layer protecting the display structure from moist and other environmental effects; the display structure further comprises, when applicable, a number of structured, through-holes reaching through the whole display structure; the display structure is configured to be constructed from smaller, manufacturable sized display modules by interconnecting suitable amount of display modules into rows and columns; and the display structure is applicable to harsh environments comprising ice and outdoor conditions. Various coating layers and materials can be selected for the ice application use and for the outdoor use. The corresponding manufacturing method is also part of the inventive concept.

A luminaire module delivers light with a beam angle of α. The luminaire module includes a light emitting module and a reflector positioned symmetrically about an axis. Light produced by the light emitting module exits the light emitting module from one or more spatially-extended light emitting portions. The light emitting portion(s) is (are) fully contained within a spatially extended notional design envelope which is used to guide the design of reflector and its corresponding reflective surface, such that when any light exiting the light emitting portions through the design envelope strikes the reflective surface of the reflector, the light does not return to the source and escapes from the luminaire module within a beam angle α, with no more than a single reflection from a reflector.

A main light and a secondary LED light for generation lumination of particular light characteristics in a particular direction. This includes an LED lighting fixture having a main light in a ceiling/wall lamp and a nightlight transmitting nightlight illumination along a ceiling. Downlights are disclosed having a main illumination source a secondary lumination source as a nightlight or some other illumination.

It is an object of the present invention to provide a small and simply-structured light-source device. A light-source device according to the present invention includes a laser light source section, a stem on which the laser light source section is mounted, a cap with an opening, the cap being bonded to the stem in such a manner that the cap covers the laser light source section, a lens holder joined to an outer surface of the cap in such a manner that the lens holder extends over the opening, and a collimating lens supported by the lens holder, the collimating lens collimating a light ray emitted from the laser light source section and then passing through the opening.
