Abstract
Light fixtures having a plurality of light-emitting diodes that maximize the amount of direct light into an intended area. The light fixture may include a carriage with a first (top) end and a second (bottom) end. A hood may be mounted to the first end of the carriage. At least one light engine comprising a plurality of light sources is mounted to the hood. The light sources emit light downwardly directly onto an intended area. In certain embodiments the second end of the carriage is shaped and sized so that it does not interfere with emission of the light to the intended area. The light fixture thus provides light in a thermally efficient manner, maximizes the amount of direct light, and limits the amount of light pollution.
