Car lighting – return of the ‘light bulb’, and other Osram LEDs at CES

Osram is offering replaceable LED lighting modules to car makers. Designed to the requirements of ECE standard R128, the hand-replaceable sources are available in red, yellow and white. They are branded ‘XLS’ for exchangeable LED light sources. The parts are LR5, LY5 and LW5 respectively, with LR5 and LY5 intended for indicator and tail light light guides, LR5 also ...

Lattice picks FD-SOI and redesigns FPGAs for embedded vision and edge AI

Lattice has switched to 28nm FD-SOI (fully-depleted silicon-on-insulator) technology for a range of sram-based FPGAs intended for embedded vision and artificial intelligence processing in industrial, automotive and consumer systems. Although they are ram-based, and therefore need to boot from adjacent memory, the firm has found a way to get chip outputs enabled, set and stable within ...

4kW 24V industrial PSU takes 3∅ input

TDK has announced a 4,080W 24V industrial power supply, that operates from three-phase ac mains between 350 and 528Vac. Called TPS4000-24 “the TPS series can operate automatically from 400, 440, and 480Vac nominal delta or Y inputs, without wiring changes or the need for step-down transformers,” according to the firm, which sees the PSU being used to ...

Harvey Nathanson, father of MEMS, dies

The creator if the first MEMS device, Harvey Nathanson, has died. He built a resonant horizontal wand-like structure while working for Westinghouse in the 1960s. “Working out of the Westinghouse Research Labs in 1965 he conceived of a microscopic device used as a tuner for microelectronic radios,” according to this obituary by Ralph Schugar Chapel in ...

Colour consistency metric proposed for LED lighting

French optical firm Gaggione has proposed a way to compare the evenness of colour in ‘white’ light beams produced by LED lighting – generally those with separate RGBW die as light sources. It is an approximation technique, as is expected to be used in a similar way to other optical approximations such as ‘colour temperature’, ...
