Claim One:
1. A fiberoptic luminaire with scattering and specular sidelight extractor patterns, comprising: (a) a fiberoptic light pipe having a light-carrying core; (b) an elongated side-light emitting portion of the light pipe having a main axis and emitting light from the side of the light pipe for illuminating a target area; the light pipe emitting light from said side by a side-light extractor pattern arrangement comprising: (i) a scattering extractor pattern for light and a specular extractor pattern for light, each of which directs light onto the target area; (ii) the scattering and specular extractor patterns being positioned on said side-light emitting portion so as to extract light from the side-light emitting portion over a radial angle, orthogonal to said main axis, of less than 180°; (iii) the scattering extractor pattern comprising a Lambertian type of extractor pattern and the specular extractor pattern comprising some or all of surface areas of one or more notches in the side-light emitting portion, each of which notches has a pair of main faces parallel to within 10° of each other; and (c) the specular extractor pattern extending over less than 20% of a length of the side-light extractor pattern arrangement along said main axis.
