20120112640 | Sustainable Outdoor Lighting System for Use in Environmentally Photo-Sensitive Area - Provided herein are systems and methods for outdoor lighting, which generally include two or more light sources. One light source is a monochromatic light source producing a light with a peak wavelength of about 580 nm or above. A second light source is a polychromatic light source producing a green-tint white light. During a standby operational mode, a control system maintains the first light source illuminated. The control system, which includes an integrated imaging system, illuminates both the first light source and the second light source when the imaging system identifies a target in an illumination area. Methods of preparing and using such outdoor lighting system are also provided. | 05-10-2012 |
20120138545 | LED Fluid Purification System and Method - Provided herein are systems and methods for the treatment and purification of fluids (e.g., water) using a light-emitting diode (LED) light source. In one embodiment, for example, there is provided a fluid flow conduit having an LED light source and a photo-catalytic material disposed therein. The LED light source emits ultraviolet light with a peak wavelength between about 265 nm and about 400 nm. In operation, the photo-catalytic material absorbs the ultraviolet light from the LED light source, and releases free radicals into the fluid. The free radicals then degrade organic substances (e.g., bacteria) in the fluid. | 06-07-2012 |

20130257312 | SYSTEM FOR GENERATING NON-HOMOGENOUS BIOLOGICALLY-ADJUSTED LIGHT AND ASSOCIATED METHODS - A lighting system including a plurality of luminaires capable of generating polychromatic light having a dominant wavelength in the visible spectrum and arranged into an array and a computerized device electrically coupled to the plurality of luminaires so as to selectively operate each individual luminaire to produce source light varying with each other and with time. The computerized device operates the luminaire such that each luminaire emits a source light, the source lights combining to form a combined light having selected characteristics. Each of the plurality of luminaires may be operable to emit light having increased spectral opponency, thereby reducing melatonin suppression. The source lights, when perceived directly, recreate a lighting scenario having varying lighting characteristics. | 10-03-2013 |
