Provided is a light beam emission device and a light beam projection device, that are downsizable, have a simple configuration, and simplify complicated processing of video signals, such as the timing adjustment of video output signals, without generating color irregularity. The devices include: a plurality of light sources; and a condensing member. A range in the light source array direction, in which emission spots of the light beams emitted from the plurality of light sources respectively exist, is within a size in the array direction of a light beam, immediately after the light beam emitted from an emission spot located most closely to the center of the plurality of light sources, with respect to the condensing member, passed through the condensing member.

A light fixture has an elongated track comprising an upper channel comprising a first wall having a first slot and a second wall having a second slot. The assembly has a support assembly comprising a base and a swivel arm rotatably attached to the base at a swivel. The base comprising a first flange received in the first slot and a second flange received in the second slot, said base extending across the upper channel. The swivel arm has a first end and a second end. The swivel is disposed at the first end and a cable connector is disposed at a second end of the swivel arm. The cable connector receives a cable therein.

The invention provides a light generating system (1000), configured to generate system light (1001), wherein the light generating system (1000) comprises a light source (10), a first luminescent material (210), and a control system (300), wherein: the light source (10) is configured to generate light source light (11) having a tunable spectral power distribution within a first wavelength range (.sub.x1); wherein the light source (10) comprises a superluminescent diode; the first luminescent material (210) is configured to convert at least part of the light source light (11) into first luminescent material light (211) having one or more wavelengths in a first luminescent material light wavelength range (.sub.m1); the first luminescent material (210) is configured such that in an operational mode the system light (1001) comprises the first luminescent material light (211); a spectral power distribution of the system light (1001) is controllable in dependence of the spectral power distribution of the light source light (11); and the control system (300) is configured to control the spectral power distribution of the light source light (11).
