Allegro MicroSystems Europe has added the A8518 and A8519 LED driver ICs to the companys portfolio for LCD backlighting applications. The ICs are multi-output boost converter devices with built-in fault-tolerant protection.
Adaptive matrix LED headlights are one of the innovations in the automotive industry that clearly improve driving safety and thus spread quickly across vendors. The obstacle to adopt them also in the more affordable vehicle classes lies in its cost, and in this context matrix drivers are a major cost block. Texas Instruments (TI) now has introduced a LED matrix manager that integrates these functions on a single chip, shattering the price barrier to the lower end. As a side effect, the chip enables designers to drastically reduce the size of their PCBs.
Scientists from Tohoku University in Japan have developed a new type of energy-efficient flat light source based on carbon nanotubes with a low power consumption of around 0.1 Watt for every hour's operation which is about a hundred times lower than that of an LED.
University of Manchester spin-out company Nanoco Group plc has signed a follow-on joint development agreement with Osram, one of the world's largest lighting companies, in connection with the use of Nanocos cadmium-free quantum dots in general lighting applications.
