Abstract: At least one array of LEDs (e.g., in a flip chip configuration) is supported by a substrate having a light extraction surface overlaid with at least one lumiphoric material. Light segregation elements registered with gaps between LEDs are configured to reduce interaction between emissions of different LEDs and/or lumiphoric material regions to reduce scattering and/or optical crosstalk, thereby preserving pixel-like resolution of the resulting emissions. Light segregation elements may be formed by mechanical sawing or etching to define grooves or recesses in a substrate, and filling the grooves or recesses with light-reflective or light-absorptive material. Light segregation elements external to a substrate may be defined by photolithographic patterning and etching of a sacrificial material, and/or by 3D printing.

Abstract: An apparatus for cleaning of tubular threads having adjustable spacing brushes to accommodate tubulars of different diameters. A plurality of brushes are rotated in a drum, which fits over the tubular connection. The brushes are mounted on L-shaped brackets, which are in turn mounted to a rotary driver by a shaft extending through slots in the brackets. By loosening the attachment of the brackets on the rotary driver, the brackets can be slid radially inward or outward to the extent of the slots, thereby adjusting the diameter of the threads that can be cleaned. The front access plate and seal plate, through which the tubular extends into the drum, are preferably held to the drum by hand operable latches. Solvent may be injected into the drum and onto the threads by a hand pump, and captured in the drum and drained into a container for disposal or reuse.
