The invention provides a lighting device (12) configured to provide both functional lighting for illuminating a space, and simultaneously to present a spatially dynamic sparkling light display. The device comprises a chamber (14) containing one or more light sources (28). The light sources are arranged to direct light in the direction of a translucent surface portion (20), and in the direction of a plurality of light exit areas (32) delimited by the translucent surface portion. The light exit areas each have a higher transmittance than the surrounding surface portion.

A light fixture includes a housing defining a recessed cavity. The housing has a top, a first side, and a second side each extending at an angle from a first end of the housing to a second end of the housing, the first end being substantially orthogonal relative to a first plane. One or more lamp units are positioned in the housing to emit light therefrom, wherein the emitted light is prevented from leaving the housing in a direction parallel to the first plane.

The present invention is a flexible thin film based screen or illumination apparatus with a stacked layer structure or a one-layer structure. Transparent polymer is preferably used in different layers, and energy can be collected directly by a solar panel layer of the screen structure. Different resolutions are available through using a various number of layers with LEDs. Frames and connecting means can be used and a special connection principle enables selected layers of a single module, and/or selected layers of adjacent modules to be electrically coupled. The present invention can be used in any planar or non-planar shape, and as a single-sided or dual-sided LED screen or illumination device, e.g. as information screens, traffic information means, advertisement platform, in architectonic media surfaces, in sports venues, and for various entertainment purposes. Wireless and IoT connectivity means can be provided in the apparatus.

An illuminating device can comprise two substrates each having two surfaces, one of each can be configured to mount solid-state lighting devices wherein the two substrates are separated by a defined gap. The two substrates are electrically and mechanically connected and can support or be supported with an enclosure such as an optic. This configuration provides thermal decoupling and uniform illumination when assembled as per the embodiments explained.

An improved light assembly includes aligned directional light sources mounted one behind another. A distal one of the light sources occludes light emitted from a proximal one of the light sources. A reflector is interposed between the light sources, with a convex surface facing the proximal one of the light sources. Thus, the light assembly projects a light field extending at least through an 180 hemisphere, and up to about 270 backwards from the forward orientation of the light field, well-illuminating lateral approaches to the assembly.

A lighting apparatus that includes a flexible circuit substrate that has a front face and an opposite back face, and a first end and an opposite second end; a first plurality of LED dice on the flexible substrate, wherein each die of the first plurality of LED dice emits blue light; a second plurality of LED dice that emits red light; a third plurality of LED dice that emits infrared, wherein the first, second and third plurality of LEDs each emit a full-width-half-maximum bandwidth of no more than 50 nm in each of their respective colors. Some embodiments provide variable spacing to the apparatus and variable scheduled lighting periods and accommodate various types of botanical plants.
