Blue LED Chip Price Drop: Reasons and Impacts

The price of blue LED chips has dropped to almost half compared to the price last year, putting a great pressure on many manufacturers. The price of 4-inch wafer has fallen from US$ 22 in 1Q17 to around US$ 15 in 1Q18. As the cost is about US$ 15, the decrease of price could lead to deficit for LED chip makers.

Purple LEDs to Replace Blue LEDs?

“It is only a matter of time before white LEDs using blue LED chips will disappear from the market,” said Shuji Nakamura at a forum on GaN technology in July organized by Nikkei Asian Review. The comment from the inventor of the blue LED chip and Nobel Laureate shocked the industry. Nakamura shares a Nobel Prize in Physics with two Japanese inventors Isamu Akasaki and Hiroshi Amano for their invention of the blue LED. Yet, Nakamura’s recent remark completely derails his previous accomplishments. Industry insiders in China try to decode Nakamura’s comments to determine whether it reflects embedded flaws in blue LEDs design, or whether his motive is to promote Soraa’s purple LEDs.

Blue LEDs Show Promise in Preserving Foods in Fridges

A team of scientists from the National University of Singapore (NUS) has found that blue light emitting diodes (LEDs) have strong antibacterial effect on major foodborne pathogens, and are most effective when in cold temperatures (between 4°C and 15°C) and mildly acidic conditions of around pH 4.5.

Japanese Blue LED Inventors Awarded Nobel Prize in Physics 2014

This year’s Nobel Laureates are rewarded for having invented a new energy-efficient and environment-friendly light source – the blue light-emitting diode (LED). In the spirit of Alfred Nobel the Prize rewards an invention of greatest benefit to mankind; using blue LEDs, white light can be created in a new way. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light sources.
