Abstract: An injection-molding apparatus for article formation. The injection-molding apparatus includes a single mold base supporting at least one grouping of a plurality of shape-forming configuration sets. Each set includes at least one cavity and is shaped for forming one of first-formed, intermediate-formed and last-formed regions of the article in the cavities by a corresponding one of injection-molding shots. Each cavity retains each article region formed by the preceding injection-molding shot(s). The single mold base includes a movable part which moves internally within the single mold base with respect to a stationary part such that relative positions of the shape-forming configurations are advanced for each set to form a subsequent article region in the cavities. Each subsequent injection-molding shot may at least partially over-mold the article region formed in the preceding shot. Each subsequent shot may be prior to full cooling of the article region formed in the previous shot.

Abstract: A light emitting diode (LED) package comprising an encapsulant designed to improve color spatial uniformity in comparison to hemispherical encapsulants is described. In some embodiments, the encapsulant comprises a segment of a hemisphere as a lower portion and an upper portion of a second shape. In some embodiments this second shape is defined by a spline curve. The encapsulant improves color uniformity over a wide range of angles while only minimally affecting other attributes such as photometric polar distribution, extraction efficiency, and luminous intensity. Embodiments of the present invention can also utilize light emitting systems comprising such LED packages.

Abstract: A troffer light fixture has a housing with a LED assembly positioned in the housing. The LED assembly includes at least one LED array comprising LEDs of at least two different colors. The LED assembly includes a first LED array having a first LED on a first string and a second LED on a second string and a second LED array having a third LED on a third string and fourth LED on a fourth string. A wide lens covers the LED array. A reflector assembly has a first reflective surface and a second reflective surface reflecting light from the at least one LED array laterally across the width of the wide lens. Alternatively, the LED array may be approximately one-half the width of the wide lens and the reflector may be eliminated.

Abstract: A light fixture includes a LED assembly and a housing. A lens assembly comprises a lens and a first end cap and a second end cap. The end caps are releasably connected to the housing such that the lens and the end caps are releasably mounted to the housing as a unit. The end caps may be releasably mounted to the housing by a deformable, resilient first engagement member that releasably engages a second engagement when the lens assembly is moved relative to the housing in a first direction. A force is created between the first engagement member and the second engagement member sufficient to hold the lens assembly in the housing and low enough that the lens assembly is removable from the housing by pulling the lens assembly in a second direction opposite to the first direction.

Abstract: A method for manufacturing of a lens for distribution of light from a light emitter. The method provides an injection-molding cavity defined by a shape-forming configuration with a texturing in at least one area of the cavity. A thermoplastic elastomer is injected into the cavity shaping a lens-region thickness of the elastomer. Such lens-region thickness is cooled and set prior to sinking of the elastomer such that the lens-region thickness retains the texturing of the shape-forming configuration forming a textured surface portion of the lens.

Abstract: A LED lamp for use in an existing light fixture may be used in either a base-up or a base-down orientation. The lamp includes an at least partially optically transmissive enclosure. A LED assembly is located in the enclosure and emits light when energized through an electrical path. A heat sink dissipates heat from the LED assembly where the heat sink is connected to the enclosure such that the lamp has a longitudinal axis that extends from the heat sink to the enclosure. A reflector reflects light along the longitudinal axis of the lamp. The reflector may be oriented to reflect light either toward or away from the heat sink.
