    Abstract: A lens for distribution of light from a light emitter. The lens has thick and thin wall portions between inner and outer lens surfaces. The thick wall portion(s) are at least twice as thick as the thin wall portion(s). At least one of the inner and outer surfaces has a texturing for diffusion of emitter light passing therethrough. The lens may include at least one interface between two materials with different indices of refraction. At least one surface of the interface may have a texturing for diffusion of emitter light passing therethrough. And, a method for manufacturing of the lens by forming a lens region with a textured surface portion by injecting the thermoplastic elastomer into an injection-molding cavity defined by a shape-forming configuration with a texturing in at least one area of the cavity. The shape-forming configuration is configured to shape a thermoplastic elastomer into such thickness that the set elastomer retains the texturing.

    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 is shaped for forming one layer of a multilayered article comprising an asymmetric surface. Each set may include at least one cavity which retains each article region formed by the preceding injection-molding shot(s). The single mold base includes an internal movable part which moves 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 shot may be prior to full cooling of the article region formed in the previous shot.

    Abstract: LED lighting apparatus including (a) a circuit board which has a plurality of light sources spaced thereon, (b) a heat sink to which the circuit board is thermally coupled, and (c) a securement structure which includes a rigid peripheral structure applying force along a peripheral area of the circuit board toward the heat sink to increase the thermal coupling therebetween to facilitate heat transfer from the light sources during operation. The lighting apparatus may also include an optical member with a plurality of lens portions over corresponding light sources and a peripheral region, the securement structure engaging the peripheral region which sandwiches a gasket against the heat sink. The apparatus may use manipulation involving surface convexity, such as bowing, thereby allowing the securement structure to further facilitate surface-to-surface thermal coupling between the circuit board and the heat sink.

    Abstract: A lens for distribution of light from a light emitter having an emitter axis. The lens includes an inner surface defining an inner cavity and including a substantially cross-sectionally convex inner region along an open end of the inner cavity and a substantially cross-sectionally linear inner region joining the substantially cross-sectionally convex inner region and extending therefrom toward the emitter axis. The convex region is configured for refracting emitter light rays toward the emitter axis. The lens further includes an outer surface receiving the light from each of the inner regions. A lens flange surrounds the lens and has an outer flange surface extending radially outwardly from the lens outer surface at positions axially spaced from the light emitter. The convex inner region is configured to refract emitter light to the outer surface such that the outer flange surface is substantially free from receiving any emitter light.
