1. An illumination system comprising:

  • a housing extending along a first direction, and including a dielectric core and a layer comprising a metal disposed on the dielectric core,wherein the dielectric core comprisesa base portion oriented in a first plane that contains the first direction, andan arm portion oriented in a second plane that contains the first direction, wherein the base portion and the arm portion are integrally formed to define an L-shaped profile of the dielectric core in a transverse cross-section orthogonal to the first direction, anda support structure integrally formed with the arm portion and oriented parallel to the first plane,wherein a portion of the housing includes traces formed from the layer comprising the metal;

    a plurality of light-emitting elements (LEEs) secured to the portion of the housing which includes the traces, the light emitting elements being operatively connected to power via the traces and arranged along the first direction;

    one or more optical couplers extending in a forward direction orthogonal to the first direction, the optical couplers positioned to receive light emitted by the LEEs and configured to collimate the received light, wherein the optical couplers are mechanically connected with a portion of the housing which comprises the arm portion of the dielectric core;

    a redirecting surface spaced apart from the one or more optical couplers at a first distance along the forward direction, the redirecting surface configured to reflect the collimated light as output light in a backward angular range; and

    a reflector arranged and configured to reflect the output light in the backward angular range to an ambient environment as reflected light in a forward angular range, wherein an edge of the reflector is supported by the support structure of the dielectric core.
