摘要: Illumination systems with selectively adjustable illumination patterns which reduce the need for a utility or luminaire distributer to stock luminaires with different illumination patterns and reduce the need for pre-planning installations. Implementations may allow scheduled dimming of luminaires, dimming in defined physical directions and scheduled adjustment of light patterns. The efficiency and/or color contrast of a luminaire may be improved by using wavelength shifting material, such as a phosphor, to absorb less desired wavelengths and transmit more desired wavelengths. A transmissive filter may reflect desired wavelengths such as red and green, while passing less desired wavelengths (e.g., blue) toward the wavelength shifting material which emits such as light of more desirable wavelengths.

摘要: A lighting device that can switch between intensity distributions of emitted light with a simple configuration. The lighting device includes a light source, a polarization controller, and a polarizing plate, in which the polarization controller switches light emitted from the light source between light components having two or more different polarization states to be incident into the polarizing plate, and the polarizing plate functions as a diffraction grating that has two or more regions having different polarization states of transmitted light in an in-plane direction and where one or more regions among the regions are periodically disposed.

摘要: A lighting device comprising a light source being configured to generate source light of a white light emission spectrum having a color correlated temperature (CCT) in a range of 2500-20000K and comprising a control unit being configured to control a lighting element for tuning of the source light with respect to a ratio between a first emission peak in a wavelength range of 460-490 nm and a second emission peak in a wavelength range of 430-460 nm. Thus a lighting device with a tunable/adjustable spectrum is provided that can switch between a first operation state of energy efficiency lighting with a blue peak in the second wavelength range of 430-460 nm, but with blue hazard risk, and a second operation state of less efficient but safe, healthy lighting with a biological stimulant having a blue peak in the first wavelength range of 460-490 nm.

摘要: A lighting device includes: a first optical unit and a second optical unit. The first optical unit includes a primary light source and dichroic separation optics. The primary light source is configured to emit primary light in the visible spectrum. The dichroic separation optics are configured to intercept at least part of the primary light generated by the primary light source and emit, from a first emission surface, at least one first highly collimated light component and at least one diffuse light component. The at least one first highly collimated light component and the at least one diffuse light component forms a light with chromatic components having different angular distributions. The second optical unit includes secondary collimation optics is configured to generate, from the light with chromatic component, a weakly collimated light component and a second highly collimated light component.

摘要: A lighting apparatus may include a light generating device for generating a primary light beam, a phosphor body that can be irradiated by means of the primary light beam and serves for partly converting primary light of the primary light beam into secondary light, and a spectral filter disposed downstream of the phosphor body. The spectral filter may be more highly transmissive to the secondary light than to the primary light where the spectral filter is arranged along a beam axis of the primary light beam incident on the phosphor body. The lighting apparatus may be used in LARP arrangement for vehicle lighting, general lighting, exterior lighting, stage lighting, effect lighting, etc.

摘要: A light source includes features configured to compensate for discontinuous solid state sources. The light source can produce a wide color gamut in display, and improved color rendering of tissue under observation by phosphor gap filling with colored LEDs. The light source can include provisions to depart from a white light spectrum to heighten differences in anatomical features or functions. The light source can include provisions to introduce narrow-band solid-state sources for producing false-color and pseudo-color images, with variable color rendering to change the power spectral distribution and to compensate for fiber optic length and fiber optic diameter tip sensing.
