From this week's DVN newsletter:
Quote:
...SoraaLaser, the laser-focused outgrowth of blue/white-LED Nobel laureate Shuji Nakamura's Soraa LED lighting company, have developed the first commercially viable, efficient solid-state, white-light laser source. It boasts a luminance up to 100 times better than that of white LEDs…
...SoraaLaser have produced white-light SMDs (surface-mount devices) that produce up to 500 Lm from a 300-μm emitting area…
...To produce these white-light laser SMDs, a high-power blue InGaN semipolar laser diode excites a very small (ø< 300 μm) remote phosphor target that converts the laser light to eye-safe, broad-spectrum, incoherent white light….
...The 7×7-mm SMD package consists of the blue laser diode chip illuminating a 300 μm area of the 1×1-mm phosphor in a reflective configuration, with a "beam dump" that blocks any blue light that could reflect from the single-crystal phosphor…
...Even though the efficacy (in Lm/W)) of laser diodes, at 30–40%, is less than the 50–60% efficacy of LEDs, the key metric in directional lighting applications is Lm(target area)/W. By this metric, laser-diode illumination improves dramatically beyond 10 m compared to LEDs.….
Right now, this technology costs substantially more than LED, but SoraaLaser says it will be showing up soon on some high end vehicles (and in other types of lighting).
I am not looking forward to having ever brighter headlights blinding me. Will welder's goggles be required equipment for night driving 10 years from now?
