Osram is aiming at torches and work lamps with a long-life 160 lm LED. Called Osconiq P 3030, it is build around a 1 x 1mm die that can be driven at 1.3A and comes in a specially-developed 3 x 3mm (1.63mm high) SMD epoxy package with lead-frame heat spreading and a silicone lens. “Compared with the ceramic packages commonly used ...

Renesas has introduced a family of 15Mbit/s optocouplers for harsh industrial applications. “The trend toward higher voltage compact systems is driving stricter international safety standards that require smaller ICs with lower power consumption,” said the firm. “The RV1S9x60A family meets this need with low threshold input current ratings.” RV1S9160A – SO5 package – operates at 2mA RV1S9060A – LSO5 package ...

UK distributor, Ideal Power, has added the latest LED driver from Xelite to its portfolio. the XT-GR dimmable LED drivers support motion sensing for LED lighting in smart buildings, where they can offer cost and energy savings. The drivers are supplied connector-ready for a motion sensor which will activate the lighting when required. The drivers can be used for interior ...

Devon-based LED maker Plessey has announced a display device design and long-term supply agreement with smart glasses and augmented reality (AR) company Vuzix. It will support the development and production of AR products that combine Plessey’s “micro-LED light source technology”, according to Plessey, with Vuzix’ expertise and intellectual property in smart glasses and essential optics technologies. Vuzix has already created ...

Osram Opto joins a German project to explore the principles of high-resolution displays using arrays of micro LEDs.

The STMicroelectronics LED1202 12-channel LED driver can store eight programmable patterns and sequences.

Plymouth-based Plessey has revealed green-emitting micro-LEDs made on a planar gallium nitride on silicon (GaN-on-Si), whose light is not made by phosphor conversion. “To produce green light, LED manufacturers typically apply phosphors or quantum dot conversion materials to native blue LEDs. These materials then convert short wavelength, typically 450nm blue, to red or green wavelengths with typically 10% to 30% ...

Nexperia has extended its constant current LED driver family with eight new AEC-Q101 qualified devices that deliver up to 250mA. The 16V NCR32xx and 40V NCR42xx series are available in two package styles, the smaller SOT457 (SC-74) or higher power SOT223 (SC-73) – the latter which works up to 1.25W. Output is stabilised at 10mA without an external resistor, and ...

Lights are the most prevalent electrical components in any commercial building, and that makes them the most logical devices for smart building sensors, according to Russ Sharer, vice president of global marketing and business development at Fulham. “In new construction you can plan to use standalone smart building control sensors, but only 8% of commercial space is new construction. However, ...

Vishay has announced an AlGaN mid-power ultra-violet LED for water purification, air purification, surface sterilisation, medical disinfection, and portable sanitisers. Called VLMU35CM00-280-120, it comes in a 3.5 x 3.5 x 1.2mm surface-ceramic mount package with a quartz window. Because of this construction, the firm is claiming “extremely long lifetime” – however, nowhere in the data sheet nor the product page can I find any ...
