1. An apparatus comprising a lighting assembly for illumination of a billboard, the lighting assembly comprising:

  • a plurality of means for emitting light;

    means for mounting the plurality of means for emitting light;

    means for conducting heat thermally coupled to a first major surface of the means for mounting the plurality of means for emitting light, the means for conducting heat including a plurality of fins extending away from the means for mounting a plurality of means for emitting light,wherein the plurality of means for emitting light is attached to a second major surface of the means for mounting a plurality of means for emitting light, wherein the second major surface is opposite the first major surface, wherein the plurality of means for emitting light is arranged in two rows and each row includes more than one of the plurality of means for emitting light; and

    a plurality of means for directing light that all have substantially the same structure, wherein each means for directing light of the plurality of means for directing light is proximate one associated means for emitting light of the plurality of means for emitting light such that light from each means for emitting light of the plurality of means for emitting light is configured to exit towards the billboard from an associated means for directing light, wherein each of the associated means for directing light comprisesa first side, a second side opposite the first side, and a third side perpendicular to the first side and the second side,a first element disposed at the first side,a second element disposed at the second side, anda third element disposed at the third side, wherein the third element extends beyond the first element and the second element in a direction away from the means for emitting light,wherein, in the direction away from the associated means for emitting light, the first element includes a first outer surface protruding outwards and a first inner surface having a concave-like curvature and the second element includes a second outer surface protruding outwards and a second inner surface having a concave-like curvature, the second outer surface being different than the first outer surface and the second inner surface being different than the first inner surface,wherein the first outer surface joins with the second outer surface at a joint having an outer surface different from the first and the second outer surfaces, wherein the first inner surface joins with the second inner surface at the joint having an inner surface different from the first and the second inner surfaces.
