Selective Coating of White Silicone to Improve the Optical and Thermal Characteristics of White LED Packages

Abstract: We investigated the effect of selective coating of white silicone on the output and thermal performance of white LED packages for middle power lighting application. The LED package, where a Zener diode part was coated by TiO 2 particles-mixed white silicone, exhibited lower surface temperature and heat flux than those with the uncoated Zener diode. The white silicone-coated packages resulted in lower thermal resistance (R th ) than the uncoated ones. For example, the R th at 85 °C of the uncoated and coated wh… Show more

“…In order to create CaO:Sb 3+ , a process must includes steps of mixing, drying, firing, pulverizing. Initially, CaCO3, Sb2O3 and NaHCO3 need to be combined together by slurrying in the water [15], [16]. Next, the ingredients will be dried in the condition of air and then powdered.…”
