Abstract: A structure according to embodiments of the invention includes a light emitting device for emitting light having a first peak wavelength. A wavelength converting layer is disposed in a path of light emitted by the light emitting device. The wavelength converting layer absorbs light emitted by the light emitting device and emits light having a second peak wavelength. The wavelength converting layer includes a mixture of a wavelength converting material, a transparent material, and an adhesive material, wherein the adhesive material is no more than 15% of the weight of the wavelength converting layer.

Abstract: A light emitting diode module comprising: at least one light emitting diode structure, an integrated reflector arrangement that comprises a reflector surface for reflecting light from a light emitting area of the light emitting diode structure. The integrated reflector arrangement further comprises a back reflection surface for diffusely reflecting light emitted via a side surface of the light emitting diode structure back to the light emitting diode structure. The back reflection surface is directly attached to at least a part of the side surface such that during operation of the light emitting diode module an emission of stray light by means of the side surface is reduced. The invention further describes a corresponding method of manufacturing such a light emitting diode module. The invention finally describes a flash module, an automotive front lighting or a projection light emitting diode system comprising at least one light emitting diode module.

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: A packaging structure for a light emitter pixel array includes a plurality of pixels, with at least some pixels laterally separated from each other with a pixel light confinement structure. An inorganic substrate having a top redistribution layer is attached to the plurality of pixels and at least one through silicon via containing an electrical conductor is defined to pass through the inorganic substrate and support an electrical coupling with the top redistribution layer.

Abstract: Phosphor-converted LED side reflectors disclosed herein comprise pigments that are photochemically stable under illumination by light from the pcLED. The pigments absorb light in at least a portion of the spectrum of light emitted by the first phosphor converted LED. The side reflector may also comprise light scattering particles and/or air voids. The pigments, light scattering particles and/or air voids may be homogeneously distributed in the reflector. Alternatively the side reflector may be layered, with the pigments, light scattering particles and/or air voids inhomogeneously distributed in the reflector. The side reflector may comprise phosphor particles.

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 non-visible output light (e.g., infrared 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 method includes providing a set of multiple light-emitting elements disposed on a flexible polymer layer, and attaching a rigid layer to the polymer layer with a set of multiple light-emitting elements between them. 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 polymer layer surrounding that light-emitting element. The rigid layer and the polymer layer form a laminated structure that is transparent for visible light.
