SemiLEDs, the world's leading LED chip manufacturer, announced that its new I-coreTM LEDs in an optimized white package have a luminous efficacy of over 120 lm/W. It is reported that the package is carried out by National Star Optoelectronics (Nationstar, ) and Shenghui Lighting (SENGLED, ). For the LED industry, LEDs with an energy output of 120 lm/W are a huge advance, saving production costs and energy consumption to meet many applications.
The devices used by National Star and Spark Lighting to test are packaged in I-coreTM LED (45 mil) with a power of 1 W at 350 mA; however, the I-coreTM LED chip for mass production is 40 mils. After testing, it was confirmed that the I-coreTM LED chip has a luminous efficacy of more than 120 lm/W. Therefore, the two companies plan to expand production for street lighting.
I-core LED chips can achieve such good results, mainly using SemiLEDs' proprietary MvpLEDTM chip technology. The vertical structure based on copper alloy can achieve high brightness, thermal management and reliability.
The ultra-bright I-coreTM blue LED chips from SemiLEDs are available in two sizes, 40mil and 45mil.
