    摘要: An optical waveguide body includes first and second pluralities of light extraction features disposed on a first side of the waveguide body and adapted to direct light out of the waveguide body through a second side of the waveguide body opposite the first side. Each of the first plurality of light extraction features has a linear shape and each of the second plurality of light extraction features has at least one of a piecewise linear shape and a nonlinear shape. The piecewise linear shape comprises two adjacent planar surfaces with an angle therebetween of at least about 30 and at most about 180 degrees. The waveguide body further has a light coupling cavity.

    摘要: A solid state lighting apparatus can include a variable color input signal configured to indicate a target color of light output from the apparatus. A string current Pulse Width Modulation (PWM) controller circuit can be coupled to the variable color input signal, where the string current PWM controller circuit can be configured to generate a plurality of PWM signals having respective variable duty cycles to enable/disable respective particular string currents for respective variable times as the variable color input signal changes.

    摘要: A lighting device comprising first and second groups of solid state light emitters, that emit light having approximate dominant wavelength (in nm) of 441-448 (or 442-450, 444-455, 444-446, 442-445 or 444-452) and 555 nm to 585 nm, respectively. If the first and second groups are illuminated, a mixture of light would, in the absence of any additional light, have a color point within one or more of first, second, third, fourth and fifth areas on the 1931 CIE Chromaticity Diagram. In some embodiment, the lighting device further comprises a third group that emits light having approximate dominant wavelength (in nm) of 600-640 (or 605-610, 605-607, 600-606, 602-606 or 615-620). Also, methods of lighting.
