摘要： A lighting system (100A, 100B) comprises a light source (102) for emitting a light beam stripe (220B) with a plurality of light emitting units (603, 803A, 803B) forming an array in the longitudinal direction (X), and an optical element (870) at the exit side of the light source (102) extending across the plurality of light emitting units, and configured to enlarge the beam divergence in the transversal direction. The lighting system (100A, 100B) further comprises a reflector unit, a support structure (210), and a reflective surface (104) with an essentially linear shape in the longitudinal direction (X) and a curved shape in the longitudinal transverse direction (Y), and a chromatic diffusing layer (108) comprising a plurality of nanoparticles embedded in a matrix, wherein the chromatic diffusing layer (108) is positioned such that at least a portion of the reflected light beam (220A) passes through the chromatic diffusing layer (108), thereby generating diffuse light by scattering more efficiently the short-wavelengths components of the light in the visible spectral range than the long-wavelength components of the light in the visible spectral range.

摘要： A system and method provide fail-safe operation of a lighting system. A lighting level detector is used to obtain a baseline lighting level for a low-intensity light. If the detector measures less than the baseline level when an occupancy sensor determines the space is unoccupied, a high-intensity light is energized and an indication is provided to a user that the low-intensity light has failed. A method provides daylighting operation of a lighting system. An occupancy sensor can have Wi-Fi functionality to enable remote configuration of the sensor. A line voltage occupancy sensor can include an interface with low voltage devices. An occupancy sensor can include an integral interface to enable an external control system to override the sensor's normal logic under emergency conditions. An occupancy sensor can include an active temperature compensation feature. An occupancy sensor can also incorporate an automatically adjustable coverage area.

摘要： Various apparatus and associated methods involve a light source that provides light at wavelengths that substantially correlate to local maxima in the spectral sensitivity of a diurnal avian. In an illustrative example, the light source may output light primarily in wavelength bands that are not substantially absorbed by colored oil droplets and/or visual pigment in at least one type of cone in the eye of a diurnal avian. In some embodiments, the light source may include a light-emitting diode (LED) light source. Exemplary light sources may output spectral components to illuminate diurnal avians with local maxima of intensity at wavelengths that substantially correspond to local maxima in a spectral sensitivity visual response characteristic of the diurnal avians.

摘要： An apparatus and methods for retrofitting known solar simulator systems to allow the exit beam to be changed in size and location without changing the other fundamental functions of the main optical elements. The solar simulator system is provided with means for de-magnifying the exit beam to provide higher power densities at the illumination plane. By adding or replacing one final optical element, the system user can change the location of the illumination plane and the size of the illumination area. This change in size can increase or decrease the power density of the exit beam.
