Influence on the LED Luminous Efficiency from COB Packaging with Different Chip Arrangement
http://www.scientific.net/AMM.703.60
"In this work, the influence on the luminous efficiency of sapphire-based LED with different chip arrangement was studied. Three types of ten-chips LED with COB packaging including the circular, triangular and rectangular structures COB were fabricated respectively. It is indicated that the COB packaging with rectangular arrangement has the best luminous efficiency in three types of COB packaging structures. In conclusion, a better COB packaging way was developed."http://www.scientific.net/AMM.703.60
