Abstract: Light emitting devices having a first LED with a first phosphor, a second LED with a second phosphor and a third LED with a third phosphor to emit a composite white light are described. The first LED and first phosphor emit the red spectral component, the second LED and the second phosphor emit the blue spectral component and the third LED and third phosphor emit the green spectral component of the composite white light. The green spectral component has at least 30% radiant flux in a deep red spectral wavelength region.

Abstract: An inventive light source includes a substrate and a set of multiple light-emitting elements. The substrate is transparent or reflective for visible light. The light-emitting elements are positioned on or within the substrate. Each light-emitting element comprises one or more inorganic microLEDs that are arranged to generate and emit visible output light to propagate out-of-plane relative to a corresponding localized area of the substrate around that light-emitting element. Each light-emitting element of the set being sufficiently small in at least one transverse dimension, and the light-emitting elements occupying a sufficiently small fraction of an areal extent of the set, so as to enable visual observation of a scene through or reflected by the substrate along a sight line that passes through the set of light-emitting elements.

Abstract: An inventive apparatus includes a substrate and a set of multiple electrically conductive traces. The substrate is transparent or reflective for visible light. The electrically conductive traces are sufficiently transparent, or are less than 200 μm wide and occupy less than 25% of an areal extent of the set, so as to enable visual observation of a scene through or reflected by the substrate along a sight line that passes through the set of electrically conductive traces.

Abstract: A wearable optical assembly includes a transparent optical element and a set of multiple light-emitting elements positioned on or within the optical element. The optical assembly positions the optical element in a sight line of a user wearing the optical assembly. Each light-emitting element includes one or more inorganic microLEDs that generate and emit infrared output light to propagate out-of-plane away from the optical element toward an eye or face of the user wearing the optical assembly. Each light-emitting element of the set is sufficiently small in at least one transverse dimension, and the light-emitting elements occupy a sufficiently small fraction of an areal extent of the set, so as to enable visual observation of a scene, by the user wearing the optical assembly, through the optical element along the sight line of the user, the sight line passing through the set of light-emitting elements.

Abstract: An inventive light source includes a rigid layer, a polymer layer, and a set of multiple light-emitting elements. The polymer layer is attached to the rigid layer to form a laminated structure that is transparent for visible light. The set of multiple light-emitting elements is positioned between the rigid layer and the polymer layer. Each light-emitting element includes one or more inorganic microLEDs that are arranged to generate and emit output light to propagate out-of-plane relative to a corresponding localized area of the laminated structure surrounding that light-emitting element. Each light-emitting element of the set is sufficiently small in at least one transverse dimension, and the light-emitting elements occupy a sufficiently small fraction of an areal extent of the set, so as to enable visual observation of a scene through the laminated structure along a sight line that passes through the set of light-emitting elements.

Abstract: Display devices comprise an optionally transparent display area that extends to one or more physical boundaries (edges) of the device. The display area may be located on a front surface of the display device, and the physical boundaries of the device to which the display area extends may be formed by physical sides of the device that intersect with the front surface to define part of a perimeter of the front surface. The display area may comprise a microLED array that extends with the display area to edges of the device. Power and/or control electronics for the display device may be located adjacent the display area but away from the edges of the display device to which the display area extends. Two or more such display devices can be arranged (i.e., tiled) with their display areas adjacent, in contact, and facing the same direction to form an extended continuous microLED display area spanning the display areas of the two or more display devices.

Abstract: Techniques and devices are provided for sensing image data from a scene and activating primary light sources based on information sensed from the scene. Subsets of a plurality of primary light sources may be activated to emit sensing spectrum of light onto a scene. Combined image data may be sensed from the scene while the subsets of the plurality of primary light sources are activated. Reflectance information for the scene may be determined based on the combined image data and combined sensing spectra. Spectrum optimization criteria for the primary light sources may be determined based on the reference information and a desired output parameter provided by a user or determined by a controller. The plurality of primary light sources may be activated to emit a lighting spectrum based on the spectrum optimization criteria.
