Abstract: A light source can include a transparent flexible substrate. A sparse array of light-emitting diodes (LEDs) can be disposed on the transparent flexible substrate. A rigid substrate can be adhered to the transparent flexible substrate such that the sparse array of LEDs is located between the rigid substrate and the transparent flexible substrate. The rigid substrate can be adhered to the transparent flexible substrate with an adhesive layer. The sparse array of LEDs can be encapsulated in an adhesive of the adhesive layer. The adhesive can have a refractive index that is between a refractive index of the transparent flexible substrate and a refractive index of the rigid substrate, inclusive. The sparse array of LEDs can have a light-emitting area that is less than or equal to a specified fraction of a surface area of the sparse array, such as 5 percent or 1 percent.

Abstract: A light emitting diode (LED) module may include a direct current (DC) voltage node formed on a first layer. The DC voltage node may be configured to sink a first current. One or more devices may be formed on the first layer configured to provide a second current to one or more LEDs. A device of the one or more devices may carry a steep slope voltage waveform. A local shielding area may be formed in a second layer directly below the DC voltage node and the one or more devices. The local shielding area may include a substantially continuous area of conductive material. A conductive via may extend through one or more layers. The conductive via may electrically connect the DC voltage node and the local shielding area.

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 illumination system can produce a dynamically variable illumination pattern. The illumination system can include a light guide. The illumination system can include projection optics, which can contribute to the illumination pattern at relatively low beam angles (i.e., beam angles formed with respect to a surface normal of the light guide). The projection optics can include individually addressable light-producing elements that can direct light through one or more focusing elements. A controller can control which of the light-producing elements are electrically powered and can therefore control the illumination pattern contribution from the projection optics. The illumination system can also include scattering optics, which can contribute to the illumination pattern at relatively high beam angles. The scattering optics can direct light out of the light guide over a relatively large surface area, which can help reduce glare when the light guide is viewed directly.

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.

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.
