FIG. 8 shows a planar cross-sectional view of a light fixture 800, according to aspects of the disclosure. The light fixture 800 differs from the light fixture 300 of FIG. 3 in that in it includes a light guide 802 with a recess 806 in it, an LED strip 816 that is wrapped around an outer edge of the light guide 802, and a pan 808 that is provided with a lip. As illustrated, the light fixture 800 includes a disk-shaped light guide 802, having an interior opening 804 and a recess 806 that is formed around the interior opening 804. A illumination source 200 may be at least partially disposed in the interior opening, and a cap 322 may be disposed underneath the light source, while a reflector 320 is disposed between the cap 322 and the illumination source 200, as shown.

In some implementations, the recess 806 may completely or partially surround the interior opening 804. The recess 806 may have a triangular cross-section, and or any suitable shape of cross-section. A pan 808 may be disposed over the light guide 802, as shown. The pan 808 may be formed of metal and/or any other suitable type of thermally conductive material. In some implementations, the pan 808 may be thermally coupled to the base 202 of the illumination source 200. In such instances, heat that is generated by the LEDs on the illumination source 200 may be led away from the LEDs by the base 202 of the illumination source 200, into the pan 808, to be subsequently dissipated by the pan 808.
