Abstract: 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.

Abstract: A radiation image that has been stored in an image plate (19), such as a photostimulable phosphor screen is read by stimulating an information-bearing target area (13) with stimulating light (1). The information bearing target area responds to this stimulation by emitting information-bearing light (2) and reflecting backscatter light (3). The combination (4) 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 (17), such as a charge-coupled device (CCD).

Abstract: 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.

Abstract: 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.

Abstract: 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.

The first reflector portion may be configured to direct light rays in a first direction substantially perpendicular to a longitudinal axis of the luminaire, and the second reflector portion may be configured to direct light rays in a second direction. The second direction is substantially opposite to the first direction. The second reflector portion may include a reflector member in a path of a portion of the light rays being directed in the second direction. The reflector member may be configured to alter the path of the portion of light rays being directed in the second direction.

Abstract: 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.

Abstract: Illumination systems and methods for illuminating one or more remote locations and/or objects from a single light source are disclosed. The illumination systems include a light source that emits light, a radial collimator to partially collimate light, and a plurality of morphing elements to couple the partially collimated light into optical fibers.
