A lighting assembly includes a light guide and solid-state light emitters to edge-light the light guide, the light emitters arrayed along a transverse direction. The light guide includes two or more sets of optical elements of well-defined shape. Light output from the lighting assembly by the first and second set of optical elements have a first and a second light ray angle distribution, respectively. The optical elements are configured such that when measured in a plane perpendicular to the light guide and the transverse direction: 1) the first and second light ray angle distributions are significantly narrower than an omnidirectional output distribution; and 2) the peak of the second light ray angle distribution is displaced from the peak of the first light ray angle distribution. |
