Abstract: An LED-based lamp can be made to have a form factor compatible with fixtures designed for MR16 lamps. Such a lamp can have a housing that provides an external electrical connection. Inside the housing is disposed a single emitter structure having a substrate with multiple light-emitting diodes (LEDs) arranged thereon. Different LEDs produce light of different colors (or color temperatures). For example, at least one LED can produce a warm white light, while at least one other LED produces a cool white light and at least one other LED produces a red light. A total-internal-reflection (TIR) lens is positioned to collect light emitted from the single emitter structure and adapted to mix the light from the LEDs to produce a uniform white light. A diffusive coating is applied to a front face of the TIR lens for further color mixing.

Abstract: An optical system for a multi-color, multi-emitter LED-based lighting device can include a lens array. The lens array can include a number of color-mixing rod members extending parallel to each other along an optical axis, the color-mixing rod members being arranged and spaced so that the rear end of each color-mixing rod member aligns with a different one of the emitters. A beam-forming section can be formed at the front ends of the color mixing rod members. The beam-forming section can include nonplanar (e.g., convex or concave) front surface features, each nonplanar front surface feature being aligned with a front end of a corresponding one of the color-mixing rod members. The beam-forming section and color-mixing rod members can be formed as a unitary structure.

Abstract: A total internal reflection (TIR) lens can have a back surface tapered to provide total internal reflection of light toward the front surface. The front surface can have a stepped shape defining a cavity that extends into the lens body, with a width of the cavity increasing toward a front side of the lens. The front surface can further have a convex central surface segment that extends from the front surface within a central portion of the cavity. A peripheral cover member can be formed integrally with the lens body, with a front surface extending laterally outward from an outer edge of the front surface of the lens body and a back surface extending laterally outward from an outer edge of the back surface of the lens body.

The lens has an optical body member including an upper end, a lower end opposite the upper end, and an outer surface. The outer surface is shaped to provide total internal reflection for light from a light source. An upper surface extends in a series of steps from the upper end to a first interior portion of the optical body member. A substantially cylindrical cavity extends from the lower end to a second interior portion of the optical body member. A middle portion separates the first and second interior portions and has a flat upper surface and a curved lower surface. The diffuser has a curved shell configured for disposing over a light source and configured to fit inside the cylindrical cavity of the optical body member, the diffuser having a circular rim fused to the lower end of the optical body member.

Abstract: Zoom lens systems for LED-based spotlights include a base lens and a disk lens. The base lens can be a TIR lens with convex microlenses on a front surface. The disk lens can be generally planar. A rear surface of the disk lens can have concave microlenses complementary to the microlenses on the front surface of the base lens. A front surface of the disk lens can have convex microlenses with a different geometry from the microlenses on the front surface of the base lens. The disk lens can be movable relative to the base lens from a narrow-angle position in which a rear surface of the disk lens is in contact with a front surface of the base lens to a wide-angle position in which the rear surface of the disk lens is separated from the front surface of the base lens.
