Heat dissipation systerm should be put on the top point, as it is directly related to the lifespan. LED lighting heat dissipation features : Using high heat dissipation extruded aluminium , have big eara to make air cross ventilation, can throw off the heat of LED light effectively. Using short-range low thermal resistance, respiratory-type lamps makes the lamps reach the standards required. We get the lamps length, width, and height through the thermal simulation calculations, so as to reach heating dissipation reasonably.
