Japanese newspapers are reporting today that Mitsui Kinzoku, an Osaka-based mining and smelting company, might have paved the way to more powerful and ecological LEDs in the future.
The key is a mix between red and blue phosphor, combined with blue LEDs, which leads to the production of extremely pure white light (wave length: 450nm). Mitsui Kinzoku claims the white light created this way is 50% brighter than the one generated by existing white LEDs.
The efficiency of the new LEDs might be able to push forward the use of (less power-consuming) LEDs in home and industrial lamps and lighting applications. Even though the new type of sulfide phosphor Mitsui Kinzoku created is very expensive in production, the company plans to commercialize the product by the end of this year.
