Light emitting diode replacement for a fluorescent lamp

A luminaire, comprising:

• a substrate;
• a plurality of discrete light sources which are attached to the substrate along a length of the luminaire and configured to emit light, wherein at least a portion of light emitted by the plurality of discrete light sources is emitted in a direction normal to the substrate;
• a cavity between a first body member and a second body member, wherein the cavity extends along the length of the luminaire and is positioned to receive all light emitted by the plurality of discrete light sources, wherein:
• the first body member comprises a protrusion, wherein the protrusion comprises a first light reflective surface adjacent the cavity, wherein the first light reflective surface is positioned such that all the light emitted by the plurality of discrete light sources in the direction normal to the substrate strikes the first light reflective surface and is then reflected from the first light reflective surface before encountering any other surface of the luminaire;
• and
• the second body member comprises a recess, wherein the recess comprises a second light reflective surface adjacent the cavity, wherein the second light reflective surface is positioned such that a majority of the light emitted by the plurality of discrete light sources in the direction normal to the substrate strikes the second light reflective surface after striking and being reflected from the first light reflective surface;
• and
• an aperture extending along a length of the cavity opposite the substrate, wherein the aperture is positioned to allow light reflected from the second light reflecting surface to subsequently exit the luminaire.
