A light-emitting device includes a strip-like high flexibility region and a strip-like low flexibility region arranged alternately in a direction. The high flexibility region includes a flexible light-emitting panel. The low flexibility region includes the light-emitting panel and a support panel having a lower flexibility than that of the light-emitting panel and overlapping with the light-emitting panel. It is preferable that the light-emitting panel include an external connection electrode and that a length in the direction of a low flexibility region A that overlaps with the external connection electrode be longer than a length in the direction of a low flexibility region B that is closest to the region A.

A display device including a lower cover; a circuit substrate on the lower cover; a plurality of light sources disposed on the circuit substrate; a reflection layer disposed on the lower cover; a light regulating pattern disposed close to an edge of the reflection layer; and an optical sheet disposed on the light sources. Further, the light regulating pattern changes in size as a distance from the light source changes.

An illumination device for an optical device, a microscope or a macroscope includes a first illumination source configured to emit light which is directed via an illumination beam path onto an object to be illuminated that is arranged in an object plane. At least one second illumination source is positionable in the illumination beam path, and is transparent or semitransparent as well as self-luminous. The at least one second illumination source is configured to allow light emitted from the first illumination source to pass through at least in part. The object plane having the object to be illuminated is configured to be illuminated both by the first and by the at least one second illumination source.

A luminaire element (10) for a luminaire (1), which luminaire element (10) comprises a first light-emitting device (11); a second light-emitting device (12); a frame (2) realized to accommodate the first light-emitting device (11) and the second light-emitting device (12), which frame (2) comprises a connecting interface (22, 23) realized to physically and electrically connect to a further luminaire element (10) of the luminaire (1); and wherein the first light-emitting device (11) and the second light-emitting device (12) are arranged within the frame (2) such that the first light-emitting device (11) emits to a first side of the luminaire element (10), and the second light-emitting device (12) emits to a second side of the luminaire element (10).

In an example embodiment, a lighting fixture comprising a lighting device and a mounting bracket is provided. The lighting device comprises a front cover, a back cover, a frame, and at least one LED mounted within the interior of the lighting device. The frame has an interior edge that is in contact with a perimeter of the front cover and a perimeter of the back cover. The front cover, the back cover, and the frame define the interior of the lighting device. At least one of the frame and the back cover comprises one or more attachment mechanisms. The mounting bracket comprises a junction box mounting element configured for securing the mounting bracket to a junction box or a mounting surface, and one or more attachment mechanism mating elements configured to mate with the one or more attachment mechanisms when the lighting device is rotated within the mounting bracket to secure the lighting device into the mounting bracket.

According to one aspect, an LED package comprises a plurality of LEDs and a primary optic disposed adjacent the LEDs wherein the primary optic includes protrusions for mixing light developed by the plurality of LEDs.

A light-emitting diode (LED) display module including a back panel substantially formed of a material having a thermal expansion that is less than plastic used in injection molding, a housing that frames the back panel comprised of one or more plastic molded parts, and a front face having a louver is disclosed.

A phosphor sheet includes: a stacked structure including a first phosphor layer and a pair of transparent films each being in contact with either side of the first phosphor layer; a seal layer integrally covering an area from an end face of the stacked structure to a periphery of the stacked structure; and a second phosphor layer further covering a portion of the seal layer, the portion covering at least the periphery of the stacked structure.

The invention provides a luminaire (100) comprising an array (102) of light exit windows (104, 104′, 104″, 204, 304′, 304″, 404′, 404″, 604, 804′, 804″, 804′″, 904′, 904″, 1004, 1004′, 1004″), wherein each light exit window comprises a material adjustable between at least a first state having a first translucence and a second state having a second translucence and an electrode arrangement (112) for adjusting said translucence of the material. Such a luminaire (100) can provide differing lighting effects whilst providing illumination and, additionally, differing aesthetic effects when viewed under ambient lighting. There is also provided a method of configuring the luminaire (1100), a computer program product for implementing the method (1200), a computing device including the computer program product (1300) and a lighting system comprising the luminaire (100).

A closure for a lighting fixture includes a cover having interior and exterior surfaces that defines at least a part of an enclosure of the lighting fixture. In certain aspects, the cover comprises mounts for mounting circuitry to the interior surface of the cover and at least one attachment feature for affixing the cover to a cabinet of the lighting fixture. A light source and driver circuitry are also affixed to the cover. Because the driver circuitry and the light source are both mounted to the same cover of the lighting fixture, the light source may be replaced with an alternate light source having different voltage and current specifications, for example, by replacement of the cover with another cover. In this manner, light sources having different operating characteristics and specifications may be replaced or interchanged with relative ease.
