Abstract
A luminaire to be carried by a lighting fixture. The luminaire may include a housing, a primary optic disposed within the housing having a reflective inner surface defining an optical chamber, a light source, and a heat sink defining an aperture through which light may propagate. The light source may include a plurality of light-emitting diodes (LEDs). The luminaire may further include a secondary optic positioned adjacent to the light source that may collimate and/or refract light emitted by the light source, and may form a seal between the light source and the optical chamber. The luminaire may further include a color conversion layer configured to change the color of light emitted by the light source.
