Laser lights will dominant lighting industry in future, says blue LED inventor

January 17, 2015: Nobel laureate Shuji Nakamura, co-inventor of the blue LED, has predicted that the future will be full of lasers. Adressing a press conference, he said laser diodes, which are already been used as car headlights, will gradually replace LEDs and will dominant the lighting industry. It will be used to power wireless communications networks as well.
Nakamura, a materials science professor at the University of California, Santa Barbara, pointed out that LEDs have a limitation. When the input power is increased, LEDsnot only become very bright, but their efficiency starts decreasing. However, on the other hand, the input power for laser diodes increases continuously with very high efficiency, he said.
For this major differentiation, in the near future, all lighting will be from laser-based lighting,” he added.
