Led cooling system, led cooling system is through the refrigerant to take away the heat to achieve the principle of cooling, will have a broad prospect in the field of high-power LED. Led (Light-Emitting Diode) lamp is a new type of environmental protection lighting product using semiconductor light-emitting Diode technology as the source. LED lamps are energy-saving, easy to control, maintenance free, safe and environmental protection, long service life and other characteristics, its service life can reach 50,000-100,000 hours, far more than the traditional tungsten filament lamp 1,000 hours and fluorescent lamp 10,000 hours. LED, as a new type of energy saving, environmental protection and green light source, is bound to be the trend of future development. 0.32 inch 3412AW LED Common-Cathode CC 3412AW 7-Segment digit 3412BW Display 3412BW Common-Anode CA 0.32 inch 3411AW LED Common-Cathode CC 3411AW 7-Segment digit 3411BW Display 3411BW Common-Anode CA
