An irradiation method includes irradiating an environment with light using one or more one ceiling-mounted light sources, where each ceiling-mounted light source has an optical axis oriented vertically downward, and wherein each ceiling-mounted light source emits a light distribution having more angle-integrated intensity in a higher angular range relative to the optical axis of the ceiling-mounted light source than in a lower angular range relative to the optical axis of the ceiling-mounted light source. A ceiling-mounted light source may include a support structure, one or more light emitters disposed on a surface of the support structure, and a reflector with a funnel-shaped reflective surface facing the support structure and expanding with increasing distance from the support structure along the optical axis. The light emitters may be ultraviolet (UV) light emitters whereby the light source is a UV ceiling-mounted light source.

A self-aligning connector assembly for a light fixture. In some embodiments, the self-aligning connector assembly includes a base and a self-alignment component. The base includes a first alignment feature extending from a platform and a first electrical contact, and the self-alignment component includes a second alignment feature and a second electrical contact. When the self-alignment component is positioned over and then released onto the base, the first alignment feature mates with the second alignment feature which causes rotation of the self-alignment component under the force of gravity, resulting in operably connecting the first electrical contact to the second electrical contact.
