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.

Abstract: Covers for a container including an interior area are provided. The covers include a shaped surface for facing away from an interior area of a container. Example covers can include a substantially planar surface, a substantially concave surface, and a smooth transition from the substantially planar surface to the substantially concave surface. Further examples of covers can include a first substantially convex surface, a second substantially convex surface, and a substantially concave surface. Still further examples of covers can include a second surface for facing towards an interior area of the container wherein the second surface includes a transition that substantially follows a transition of the shaped surface.
