A U.S. supplier and manufacturer of LED lighting, LED Waves, has announced that as of December 2012, the company’s LED high bay light will be equipped with “the only extruded heat sink of its kind on the market.”
Typically, LED high bay manufacturers create heat sinks using an inexpensive die casting process that “limits the potential surface area of the heat sink to that of the mold on which it is formed.” Heat sinks produced from the process of die casting feature fewer open spaces because the molds from which they are shaped must be lined with thick walls to withstand high temperatures of the metals used in the process.
According to the company, LED Waves’ extruded heat sink is developed using a process known as extrusion, in which a material is pushed or pulled through a die to achieve a “desired cross section.” The absence of outside pressure during the process allows for fine details and more distinct surfaces to be rendered through cavities in the die, maximizing surface area and the capability for heat dissipation.
