At the Strategies in Light conference in Santa Clara (1-3 March), SoraaLaser of Goleta, CA, USA (which is commercializing visible laser light sources for display, automotive and specialty applications) is presenting its light source technology, featuring what are claimed to be unique performance properties such as collimated output and waveguide delivery and providing advantages over LED, OLED and legacy sources in specialty lighting.
SoraaLaser is an independent spin-off from Soraa Inc of Fremont, CA, USA - which develops solid-state lighting technology built on 'GaN on GaN' (gallium nitride on gallium nitride) substrates - and was co-founded by the 2014 Nobel Laureate in Physics Dr Shuji Nakamura and Dr Steve Denbaars. "Laser diodes are droop-free, and can be combined with phosphors to safely produce highly directional output with superior delivered lumens per watt compared to other light sources," says Nakamura.
SoraaLaser's visible laser light sources are based on its proprietary and patented semi-polar GaN laser diodes, combined with phosphor technology. The laser light sources provide novel properties compared with other light sources by combining the benefits of solid-state illumination (such as minimal power consumption and long lifetime) with the highly directional output that has been possible only with legacy technology.
Because the laser light is focused to a small spot on the phosphor and converted to white light, SoraaLaser says that its light sources enable safe, highly collimated white light output, superior optical control with miniature optics and reflectors, along with high-efficiency fiber-optic transport and glare-free waveguide delivery. These features are suitable for specialty lighting applications including architectural, hospitality, retail, security, entertainment, and automotive, says the firm.
At Strategies in Light, SoraaLaser is presenting during the 'Quality of Light' Workshop as well as a Seminar on laser-phosphor sources. Also, in booth #949, the firm is exhibiting its laser light sources, including fiber-optic and direct-emitting white and blue laser modules.
