  • Publication number: 20250130481
    Abstract: A microlens array comprises an array of microlenses on a flat base. A spacer located along the periphery of the microlens array protrudes away from the plane of the base. The microlens array may be arranged in combination with one or more LEDs or pcLEDs with the spacer positioned between the microlens array and the LEDs or pcLEDs and thus spacing the microlenses away from the LED or pcLEDs. Arranged in this manner, the surface of the microlens array facing the LEDs or pcLEDs and light emitting surfaces of the LEDs or pcLEDs together define an air filled or evacuated gap between the microlens array and the LEDs or pcLEDs, which improves the performance of the microlens array in collimating or partially collimating light emitted by the LEDs or pcLEDs.

  • Patent number: 12100786
    Abstract: A light emitting device includes an LED having a light emitting top surface and sidewalls. A phosphor structure is attached to the light emitting surface of the LED. The phosphor structure has a light emitting top surface facing away from the LED light emitting surface, and sidewalls. A light reflective material is arranged to cover the sidewalls of the LED and the phosphor structure. A light absorptive region is defined in the light reflective material around a perimeter of the light emitting surface of the phosphor structure. The light absorptive region may be spaced apart from the perimeter of the phosphor structure by a gap. The light absorptive region may be formed by ultraviolet laser illumination of the light reflecting material.

  • Patent number: 12027566
    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 or air voids. The pigments, light scattering particles, or air voids may be homogeneously distributed in the reflector. Alternatively the side reflector may be layered, with the pigments, light scattering particles, or air voids inhomogeneously distributed in the reflector. The side reflector can include phosphor particles.

  • Publication number: 20240162199
    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.

  • Publication number: 20240160017
    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.

  • Publication number: 20230411579
    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.

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.
