5. What is the significance of the heat sink?
Semi-conductors and other electronics have a
limited tolerance to the effects of heat on lifetime
and performance. Higher power LEDs (with higher
current) are generally less efficient and result
in heat buildup. A proportionally sized heat
sink and heat transference system must be engineered
to optimize the LEDs within a fixture. The larger
the surface area of a heat sink made of a solid
conductive material such as aluminum, the more
ideal it is for creating airflow, dissipating
heat, and extending the usable light of the LEDs.
WAC Lighting designs and engineers die-cast
aluminum heat sinks proportional to the excess
heat generated by the LEDs, resulting in optimal
heat transference. |
