A luminaire includes a waveguide having first and second opposing ends and first and second opposing sides between the first and second ends. The waveguide is configured to totally internally reflect light propagating through the waveguide in a first direction and direct light propagating through the waveguide in a second direction through at least one of the first and second sides. A reflective body is coupled to the second end of the waveguide and configured to reflect light propagating towards the second end of the waveguide such that the light propagates towards the first end of the waveguide.

Luminaire having a two-way waveguide

A luminaire is provided with a one-sided diffuser, located a predefined distance below the light output ports, in order to efficiently distribute light through an upper smooth surface and a lower surface having light altering tracks where each wherein each light altering tracks distributes its received light over a range of angles within a predefined cutoff angle.

Luminaire with a one-sided diffuser

A luminaire for distributing light rays from a light source may include first and second reflector sections. The first reflector portion may be configured to direct light rays in a first direction substantially perpendicular to a longitudinal axis of the luminaire. The second reflector portion is disposed along the longitudinal axis configured to direct light rays in a second direction. The second direction may have a directional component substantially normal to the longitudinal axis and the first direction.

Low profile direct/indirect luminaires

A luminaire for distributing light rays from a light source may include a region configured to contain a lamp. The region may extend along a longitudinal axis of the luminaire. The luminaire may include first and second reflector portions disposed along the longitudinal axis. The first reflector portion may be configured to direct light rays in a direction away from the ceiling, and the second reflector portion may be configured to direct light rays in a direction toward the ceiling. The light source may be between the second reflector portion and the ceiling, with the second reflector portion defining a cusp disposed at a first side of the light source. The first reflector portion may extend through the second reflector portion and beyond the light source to a second side of the light source opposite to the first side.

Luminaires for artificial lighting

A luminaire including a lamp, reflector, collimator and optional waveguide. The waveguide can be solid or hollow or include several serially-arranged total internal reflection (TIR) components for redirecting light that has entered the waveguide. In one embodiment, the TIR components are prisms, but are provided without metallized coatings thereby significantly reducing manufacturing costs. In another embodiment, components are arranged in a vertical orientation such that light is directed downward through a collimator or upward, either directly from the lamp or as a result of reflection from the reflector.

Luminaire device that restricts light within an angular envelope

In accordance with various embodiments, particle detection systems and method for particle detection are provided. In exemplary embodiments, the particle detection system includes at least one detector and a light source that provides light. The exemplary system can further include a radial collimator disposed surrounding a sample volume, wherein the radial collimator directs the light onto the sample volume. Various embodiments include an illumination morphing element having a light output end adjacent to the radial collimator and a light input end coupled to the light source. Various embodiments can also include a plurality of detection morphing elements wherein each of the plurality of detection morphing elements includes a light input end adjacent to the radial collimator and a light output end coupled to one or more of the at least one detectors.

Optical system and method for particle detection

A radiation image that has been stored in an image plate (), such as a photostimulable phosphor screen is read by stimulating an information-bearing target area () with stimulating light (). The information bearing target area responds to this stimulation by emitting information-bearing light () and reflecting backscatter light (). The combination () of information-bearing light and backscatter light is collimated, allowing efficient rejection of backscatter light. The information-bearing light is subsequently focused onto an information receiving target (), such as a charge-coupled device (CCD).

Luminaire device

A light source for a flat panel display or a luminare includes a tubular enclosure having a linear slit in which is positioned a lens structure which may be a cylindrical rod lens or a plurality of ball lenses. The lens, whether a rod or ball structure, has an opaque white reflective strip or coating facing inward of the tubular enclosure, thereby defining two narrow slit openings through which the light can be projected into the lens structure and into an associated waveguide.

An efficient redundant light distribution system includes redundant light generation enclosures providing light to a collector array , coupled to an ultraviolet to red converter , a combination array , a distribution array and multiple projection lenses

Optical distribution components

Collimated light distribution elements and systems that are especially suited to backlighting liquid crystal displays comprise a waveguide with clocked microstructured features for directing the exiting beam off-normal, a high efficiency mirror coating comprising both TIR and specularly reflective mirror elements, and a polarization recycling system.

Optical array and collimated light distribution

High luminance display devices, typically utilized in applications requiring sunlight readability, require unique design methodologies as the thickness approaches a maximum of one-inch. The present invention relates to a high-intensity light generation engine and associated light transmission apparatus for transmitting the light generated by the engine to a remote location. The invention is especially applicable for use in constructing a back lighted display, such as a liquid crystal display (LCD), of minimal thickness, i.e., one-inch or less. A display of minimal thickness is achieved by separating a light source and other peripherals from the display device, using a remote enclosure. Such a display is most suited for use in high ambient lighting conditions where space is at a premium, such as in the cockpit of an aircraft.

Efficient light distribution system

A partially collimated light beam ( ) is sent through a substrate matrix of a plurality of nested individual joined geometrically shaped cells ( ) wherein each of the cells is further comprised of subcells ( ) contains containing a patterned volume holographic diffuser ( ) which produces a transmitted diffused light beam ( ) from each of the cells and then superimposes each transmitted diffused light beam from each of the cells to produce a combined resultant diffused light beam. The combined resultant diffused light beam has an angular luminance distribution profile curve ( ) with sharply vertical profile slopes ( ) at halfpeak points ( ) and a substantially flat and wide peak ( ), this resultant diffused light beam advantageously produces a uniform resultant luminance over a wide range of view angles with a predetermined beam spread and beam deflection angle at said predetermined viewer head box location ( ).
