A luminaire includes a core made up of a first material and an LED lighting arrangement mounted to the core. The luminaire further includes a housing made up of a second material. The second material is different from the first material. The housing including a recess in which the core is received. The housing further includes a finned part.

An edge-lit luminaire includes a housing, a lens, a light emitter, a first reflector, and a second reflector. The housing has a central opening that defines a central area. The lens includes a plurality of extraction features substantially evenly distributed over a lens area. The lens is positioned proximate the central opening, and the lens area is larger than the opening area. The light emitter is positioned adjacent the lens and configured to direct light in a direction generally orthogonal with respect to the central opening. The first reflector is positioned proximate a first surface of the lens distal the central opening. The first reflector substantially covers the first surface of the lens. The second reflector is positioned proximate a second surface of the lens opposite the first surface. The second reflector substantially covers the second surface of the lens outside of the central opening.

A downlight apparatus includes a light source, a driver box, a light housing and a heat dissipation plate. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The heat dissipation plate is placed between the light holder and the driver box for carrying away both heat of the driver box and the light source. The heat dissipation plate is a separate metal piece from the driver box and the light housing. The heat dissipation plate has a portion not covered by the light holder and the driver box and exposed to air.
