摘要： An optical integrating cavity supplies light or other radiant energy through a port to a deflector. The deflector coupled to the port may form a “fan” extending along one side or around all or part of the circumference of the cavity. Preferred embodiments use principles of constructive occlusion (diffuse reflectivity in a mask and cavity structure) together with the port and deflector structure. The cavity and mask serve as the optical integrating cavity. The constructive occlusion provides a tailored intensity distribution for radiant energy illuminating a first region; whereas the integrating cavity, port and deflector distribute another portion of the electromagnetic energy over a second field of intended illumination. The first and second areas illuminated may overlap slightly, or one may include the other, but preferably most of the two areas are separate. In some cases, the system configuration creates a dead zone between the two regions.

摘要： A thermal conductivity and phase transition heat transfer mechanism incorporates an active optical element. Examples of active optical elements include various phosphor materials for emitting light, various electrically driven light emitters and various devices that generate electrical current or an electrical signal in response to light. The thermal conductivity and phase transition between evaporation and condensation, of the thermal conductivity and phase transition heat transfer mechanism, cools the active optical element during operation. At least a portion of the active optical element is exposed to a working fluid within a vapor tight chamber of the heat transfer mechanism. The heat transfer mechanism includes a member that is at least partially optically transmissive to allow passage of light to or from the active optical element and to seal the chamber of the heat transfer mechanism with respect to vapor contained within the chamber.

摘要： Lighting systems and devices offer dynamic control or tuning of a color characteristic, e.g. color temperature, of white light. The exemplary lighting systems and devices are used for general lighting applications that utilize solid state sources to pump remotely deployed phosphors. Two or more phosphors emit visible light of different visible spectra, and these spectra are somewhat broad, e.g. pastel, so that combinations thereof can approach white light temperatures including points along the black body curve. Independent adjustment of the intensities of electromagnetic energy emitted by the solid state sources adjusts levels of excitations of the phosphors, in order to control a color characteristic of the visible white light output of the lighting system or device.

摘要： A solid state white light emitting device includes a semiconductor chip producing near ultraviolet (UV) energy. The device may include a reflector forming and optical integrating cavity. Phosphors, such as doped semiconductor nanophosphors, within the chip packaging of the semiconductor device itself, are excitable by the near UV energy. However the re-emitted light from the phosphors have different spectral characteristics outside the absorption ranges of the phosphors, which reduces or eliminates re-absorption. The emitter produces output light that is at least substantially white and has a color rendering index (CRI) of 75 or higher. The white light output of the emitter may exhibit color temperature in a range along the black body curve.

摘要： Where a lighting device uses solid state emitters and an optic processes light from the emitters, it may improve efficiency in light extraction from the emitters to have an index of refraction matching material in between emitter output and a surface of solid of the optic that receives emitted light. However, such improved out-coupling or extraction efficiency may cause an overall color shift in the output of the overall lighting device, for example, if improved emitter output reduces internal reflection and associated internal phosphor excitation. To reduce the color shift in the output of the lighting device, the device may have index matching material used in association with one or some of the solid state light emitters but not all of the emitters, so that the combined light output of the device exhibits a desired spectral characteristics, e.g. remains a desirable color of white light.

摘要： A solid state white light emitting device includes a semiconductor chip producing near ultraviolet (UV) electromagnetic energy in a range of 380-420 nm, e.g. 405 nm. The device may include a reflector forming and optical integrating cavity. Phosphors, such as doped semiconductor nanophosphors, within the chip packaging of the semiconductor device itself, are excitable by the near UV energy. However the re-emitted light from the phosphors have different spectral characteristics outside the absorption ranges of the phosphors, which reduces or eliminates re-absorption. The emitter produces output light that is at least substantially white and has a color rendering index (CRI) of 75 or higher. The white light output of the emitter may exhibit color temperature in one of the following specific ranges along the black body curve: 2,725±145° Kelvin; 3,045±175° Kelvin; 3,465±245° Kelvin; 3,985±275° Kelvin; 4,503±243° Kelvin; 5,028±283° Kelvin; 5,665±355° Kelvin; and 6,530±510° Kelvin.

摘要： For general lighting applications, a semiconductor chip produces near ultraviolet (UV) electromagnetic energy in a range of 380-420 nm, e.g. 405 nm. Semiconductor nanophosphors, typically doped semiconductor nanophosphors, are remotely positioned in an optic of a light fixture. Each phosphor is of a type or configuration that when excited by energy in the 380-420 nm range, emits light of a different spectral characteristic. The nanophosphors together produce light in the fixture output that is at least substantially white and has a color rendering index (CRI) of 75 or higher. In some examples, the fixture optic includes an optical integrating cavity. In the examples using doped semiconductor nanophosphors, the visible white light output exhibits a color temperature in one of the following ranges along the black body curve: 2,725±145° Kelvin; 3,045±175° Kelvin; 3,465±245° Kelvin; and 3,985±275° Kelvin.

摘要： A light fixture, using one or more solid state light emitting elements utilizes a diffusely reflect chamber to provide a virtual source of uniform output light, at an aperture or at a downstream optical processing element of the system. Systems disclosed herein also include a detector, which detects electromagnetic energy from the area intended to be illuminated by the system, of a wavelength absent from a spectrum of the combined light system output. A system controller is responsive to the signal from the detector. The controller typically may control one or more aspects of operation of the solid state light emitter(s), such as system ON-OFF state or system output intensity or color. Examples are also discussed that use the detection signal for other purposes, e.g. to capture data that may be carried on electromagnetic energy of the wavelength sensed by the detector.
