Technology:
Nichia Corp., a major manufacturer
of LEDs in Japan, developed a semiconductor laser that emits more than 1,000
times stronger light than the existing semiconductor laser. Because it can emit
strong light with smaller amount of power, it can reduce the power consumption
of a liquid crystal TV by more than 25%. The company has already started shipping
samples to electronics manufacturers. It plans to commercialize the newly
developed semiconductor lasers in 2016.
Nichia's newly developed semiconductor lasers
that emit strong light
The element is made of gallium
nitride and 1.2 mm long. A cover or a terminal is used to create laser light. Nichia
successfully allow a semiconductor laser to emit strong light by improving the
structure of the semiconductor element. Because a laser light has a uniform
wavelength and can be emit straight. Therefore, it permits more effective
illumination than an LED should it be employed for the backlight of the monitor
of liquid crystal TV, and power consumption of the monitor will be halved.
Mitsubishi Electric has already
developed a red semiconductor laser that emits strong light, but it has not
developed a green and a blue semiconductor laser that emits strong light. With
the Nichia’s success, semiconductor lasers of the three elementary colors that emit
strong light have been developed. Nichia plans to exhibit the research results
in the Optics and Photonics International Congress 2015 scheduled to be held in
Yokohama between 22nd and 24th of April this year.
