Nichia launches UV-B (308nm) and UV-A (330nm) LEDs
L
ED manufacturer Nichia has started mass production of the new UV-B (308nm) and UV-A (330nm) LEDs in its popular 434 Series package. While maintaining the compact 3.5mm x 3.5mm size of the 434 Series, the newly launched UV-B and UV-A LEDs deliver outputs of 90mW and 100mW respectively (at 350mA), thus maximizing flux density. With a total input power of 1.8W, the power conversion efficiencies are described as amongst the highest in the industry, delivering 5.1 per cent at 308nm and 5.7 per cent at 330nm. In addition to Nichia’s popular 280nm, 365nm, and 405nm UV LEDs, the new 308nm
and 330nm products are expected to advance the transition from UV mercury lamps to LEDs in most applications.
The 308nm UV-B LED can also be used to control diseases (e.g. powdery mildew) and insect pests (e.g. spider mites) by irradiating strawberries and other crops with UV light. Nichia has already received many requests for samples related to agriculture, healthcare, and various other fields. Product samples of discrete LEDs or LEDs mounted on boards to expedite design efforts can be requested through Nichia’s sales representatives or the Contact Form via Nichia’s website.

Engineering samples for Trixel 3 Laser Beam Scanner (LBS) for AR use cases
T
riLite’s form factor engineering samples for its Trixel 3 laser beam scanner (LBS) are now available, combining the display engine, control electronics and TriLite’s Trajectory Control Module (TCM) software. By providing all the system-level components required for evaluation, application development and test, these samples are designed to enable customers to rapidly prototype their augmented reality (AR) systems and cut time-to-market. Trixel 3 is described by TriLite as “the world’s smallest projection display”. It provides impressive compactness and light weight, coupled with brightness and accuracy. It enables AR solutions for smart glasses and a wide range of consumer
applications, with ultra-low power consumption (<320 mW) for all-day use. The engineering samples are based around the Trixel 3 optical display engine, which combines a single 2D MEMS mirror, RGB laser diodes and all optical components. The LBS unit is supplied pre-calibrated for colour alignment and distortion correction. The display engine and the driving electronics are now form factor, which is important for customers to rapidly design and prototype their AR systems leveraging Trixel 3 technology. Dr. Dietmar Gleispach, COO at TriLite, said: “With these engineering samples now available, we are very close to the final specification of Trixel 3. This represents a key milestone for having a qualified
product on a qualified
production line according to TriLite’s APQP and enabling ramp up later this year with lead customers.”
TriLite’s latest TCM software is supplied with the engineering samples. TCM is part of TriLite’s ‘software-defined display’ approach, which shifts complexity from the hardware to the software domain. It uses proprietary algorithms to ensure optimum image quality and minimum
latency, control position and brightness at subpixel accuracy, and to assure low power consumption. TCM runs on a host processor, and the engineering samples include a suitable evaluation host.
