Abstract

The present technology relates to luminaires including a housing and a luminaire module disposed within the housing, where the housing has apertures through which light that is output by the luminaire module exits the luminaire towards one or more target areas.

Claims

1. A luminaire comprising:

a housing having a first aperture;

one or more luminaire modules arranged within the housing, each luminaire module comprising;

one or more light-emitting elements (LEEs) disposed on one or more substrates and adapted to emit light in directions including acute angles relative to a first direction;

a light guide comprising an input end and an output end, and side surfaces extending from the input end to the output end, the side surfaces being shaped to guide light emitted by the one or more LEEs and received at the input end along the first direction to the output end and provide guided light at the output end of the light guide; and

a first redirecting surface optically arranged to receive at least some of the guided light, the first redirecting surface adapted to reflect the received light in directions including obtuse angles relative to the first direction towards the first aperture, wherein light passing through the first aperture is output into an ambient environment as first light output by the luminaire.
