Spotlights shell heat : mainly by conduction and convection cooling housing shell space , light and heat radiation is also a need to consider the multi-use high-power LED lighting high power LED lamp current commercial uses LED light effect . only 15% to 30% , most of the rest of the energy transformed into heat energy.
If the thermal energy is not timely and efficient convection discharge , the consequences will be very serious , so that the life of the LED floodlight can imagine the impact , sustained high temperatures will affect flood light emitting efficiency , causing the redshift of light , color cast , etc. phenomenon, but also cause device aging and other undesirable phenomena , leading LED Spotlights life is greatly reduced, in accordance with the laws of Porto Vilnius , Floodlight Shell operating temperature decreasing by 10 ℃, Spotlights life will be extended two times about.
