Abstract
A lighting system comprises a row of light emitting diodes (“LEDs”) receiving electricity and producing light and heat. The row of LEDs can be located in a channel or a groove of a piece of material, such as an aluminum extrusion or a bent piece of metal. The channel can have an optically reflective lining, for example, providing either diffuse or specular reflection. Accordingly, the channel can reflect light emitted by the LEDs. The piece of material can also include a heat sink for transferring heat from the LEDs to air via convection or air flow. The heat sink can comprise fins or protrusions that facilitate convection.
