Patent number: 8866839Abstract: A signal adapting chromacity system to control that may include a signal conversion engine to receive a source signal designating a color of light defined by a two spatial plus luminance dimensional color space, such as the xxY color space. The signal conversion engine may convert the source signal to a three dimensional color space defined within a subset gamut of a full color gamut, such as an RGW, RBW, or GBW color space. The subset gamut may include a first color light, a second color light and a high efficacy light. The signal conversion engine may perform a conversion operation to convert the source signal to an output signal, using the output signal to drive light emitting diodes (LEDs). The conversion operation may be a matrix, angular or linear conversion operation.Type: GrantFiled: July 31, 2013Date of Patent: October 21, 2014Assignee: Lighting Science Group CorporationInventors: Fredric S.

Publication number: 20140268731Abstract: A low bay lighting system which may include a fixture housing and a plurality of light sources disposed on a mounting surface in the fixture housing. The low bay lighting system may also include a power supply and an optic that is configured for emission of glare-inducing wavelength light at non-glare-inducing angles. The non-glare-inducing angles may be measured from a horizontal axis running through a medial portion of the mounting surface of the fixture housing. One or more of the plurality of light sources may be configured to emit light having a wavelength range within an anti-glare wavelength range. The light emitted at glare-inducing angles may have a wavelength range substantially within the anti-glare wavelength range.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: LIGHTING SCIENCE GROUP CORPPORATIONInventors: Fredric S.
