The ICM provides blue and red illumination through high-brightness Light Emitting Diodes (LEDs, which allows bright light with minimal heat output, Osram Semiconductors, blue LED; 470 nm, red LED, 635 nm).
Under 980 nm laser pumping, an intense upconversion white light transmission trace was observed in Tm3+/Ho3+/Yb3+ triply doped NMAG glass channel waveguide and a high-brightness light spot was achieved from the output end of the fiber connected to the waveguide channel.
Impressive recent developments of high-brightness light extraction of GaN-based nitride light-emitting diodes (LEDs) is dominated on both material techniques such as metal organic chemical vapor deposition (MOCVD) epitaxial growth and device fabrication processes.
An edge-lit backlight as a surface illuminator in the liquid crystal display achieves high brightness illumination with the light-condensing optic, composed of lamps, a light guide plate, a reflection film, a diffuse film, and a brightness enhancement film (BEF).
InGaN/GaN-based high-brightness light-emitting diodes (LEDs) and laser diodes, as the representative devices of III-nitrides, have attracted much attention owing to their important role in digital signage, high-density optical storage, and general illumination [1 10].
InGaN/GaN-based high-brightness light-emitting diodes (LEDs) have attracted tremendous attention over the past decade because of their applications in signage, back lighting, automotive headlights, and general illumination [1 5].
From the development of the blue laser to high-efficiency, high-brightness, light-emitting devices and new age tailor-made polymers capable of a host of applications in biomedical, chemical, electronics, and opto-electronics, IMRE's research into next-generation materials is likely to catalyze new industries in Singapore.
Therefore, LD-based white light sources can be advantageous for high-power and high-brightness illumination.
