For the past three years, Seoul Semiconductor's main product had been the mid-powered 5630. However, the company has recently turned its attention towards 3030 LED in 2013, to compete with Nichia's better price/performance (P/P) 767 series on the market, said Scarphen Sun, Principal Engineer for Korean LED package manufacturer Seoul Semiconductor at the company's LED Lighting Application Seminar on October 22nd.
For the first time ever, mid-powered LEDs have surpassed high-powered LEDs this year in total production value, showing wide usage of mid-powered LEDs. Though 3030 LED was well received from the market, Nichia's 757 LED received a much higher evaluation. Seoul Semiconductor and Taiwan manufacturer Lextar therefore launched 3030 LED products in hope to counter the 757 series by Nichia.
Seoul Semiconductor is the first manufacturer to release the 5640 package LED, pointed out Sun. Three years has passed since then and the company is now turning towards 3030 package LED in 2013. The luminosity of the 3030 LED products is higher than that of the 5530 spec and production costs for the 3030 is also lower than the 5630.
Aside from high P/P, Seoul Semiconductor's 3030 packaged LED also gives clients more room for design due to the reduced package size. Compared with Nichia's 757 series, chip temperature in the 3030 is lower than the 757 series by three degrees when the driver reaches 1w showing better heat dissipation performance.
The 3030 package LEDs have already entered U.S. lighting manufacturer TCP's supply chain, which is one of Nichia's biggest clients for the 757 series.
