The newly introduced 3030 LED extends the Seoul mid-power LED portfolio and offers up to the high-power one watt (1W) range. This performance was achieved by enhancing both the LED chip and package in terms of thermal resistance. Even though traditional 3030 packaged LEDs were mid-power, the new versions can be used in high power applications with the additional benefit of reducing costs by more than 50 percent over 1W high power LEDs.


Marten Willemsen, Vice President of Marketing for Seoul Semiconductor, says, “The 3030 and 5630 packages are LED products which focus on both price competitiveness (lm/$) and luminance efficiency (lm/W). We have already sold billions of pieces in China, USA, and Europe for various LED lighting products.”


He adds, “If you use these two LEDs properly, you can chase two rabbits at the same time in terms of ‘lm/W’ and ‘lm/$’ which most lighting designers consider the most important factors.”


Toshiba unleashes low power


GaN-on-Si white LEDs The two sets of gallium nitride-on-silicon LEDs are anticipated to commence mass production in August 2013


Toshiba Corporation has launched a series of white LEDs fabricated with a GaN-on-silicon (GaN-on-Si) process.


Veeco big in China with multiple MOCVD order from Sanan


The largest LED manufacturer in China will use the reactor to grsow LEDs for applications including backlighting and general illumination


Sanan Optoelectronics placed a multi-tool order for Veeco’s TurboDisc MaxBright M MOCVD systems in the third quarter of 2013.


The multi-reactor systems will be used to ramp production of LEDs in its Xiamen, China fab for applications including backlighting and general illumination.


Toshiba’s Sub-Watt Type White LEDs, TL2FK Series (left) and TL3GA Series (right)


The LEDs are low power sub-watt type, due to reduction of forward voltage (VF). Two package line-ups, the TL2FK series with 3.0 x 1.4mm package and the TL3GA series with 3.0 x 3.0mm package, will be made available. Mass production is scheduled to start from August, 2013.


The LEDs can be used in light sources for general lighting, including straight tube lights, light bulbs, base lights and ceiling lights.


Zhiqiang Lin, Chief Executive Officer of Sanan, says, “Veeco has been and remains our MOCVD supplier of choice. As we were selecting equipment for our new phase of expansion, it was evident that the MaxBright M would give us the best footprint efficiency to maximise space and productivity in our Xiamen fab. Veeco has been a great partner for us since as we have solidified our position as the top LED manufacturer in China and as we have increased our business outside of China as well.”
