FIG. 3 shows an exploded view of an example of a light fixture 300 that utilizes the illumination source 200, according to aspects of the disclosure. The light fixture 300 may include a light guide 302 and a reflector 304 disposed over the light guide 302. Although in the present example the light guide 302 is shaped as a disk having an interior opening (e.g., an opening in the middle of the disk or at another location), alternative implementations are possible in which the light guide 302 has a different shape. For example, the light guide 302 may be shaped as a rectangle or another polygon (e.g., octagon, hexagon, etc.), a rail, etc. The shape may be determined based on any applicable reason such as light distribution preference, physical space requirements, or the like. A light distribution preference may be based on an application of a light fixture, an environmental conduction (e.g., objects to illuminate, distance to illuminate, available ambient light, etc.), or a user input. It should be noted that although one or more specific light guide shapes are shown in the figures contained herein, the shape of a light guide may be adjusted to be any applicable shape that results in a desired light distribution.
