Updated: Designing led/optic assemblies gets easier

Gaggione LLC17N

Maybe everyone else has known this for ages, but at last there is enough information on led and collimator data sheets to work out how far one should be form the other to get the specified beam. Gaggione LLC17N This was bought to my attention by optics maker Gaggione – which I had know had been marking its drawings for ...

Gaggione invents a light input structure

Gaggione LLC66x7

Another one that has been around for a while, but I missed it – get in touch folks. Gaggione has reversed the shape of its collimator input cone to reduce stray light. It is implemented in its LLC66x7 silicone collimator range – presumably the optics would not come out of the mould if they were made of anything ridged – ...

Industrial-grade lighting strips

RS Components ILS led strip

Intelligent LED Solutions announce industrial grade flexible LED strips for machine lighting. Branded PowerFlex the range includes constant current drivers, protection diodes and 3M thermal tape. Led-to-led spacings from 7.5 to 25mm are available. Up to 3,500 lm/m and 50,000 hours working life is achievable. “We now have customers using the PowerFlex for machine tool lighting and it is proving far superior to traditional approaches ...

Magnetic speed sensor rejects offsets

Allegro A1667 sense

Allegro MicroSystems’ surface-mount magnetic speed sensor contains a compensating circuit that reduces the detrimental effects of magnet and system offsets. “Digital processing of the analogue signal provides zero-speed performance independent of air gap as well as dynamic adaptation of device performance to the typical operating conditions found in automotive applications, including reduced vibration sensitivity,” said the firm. Called A1667, to comes ...

Microchip extends PIC32 range downwards

PIC32MM

Microchip has created the lowest power and least costly family of PIC32 microcontrollers (MCUs), positioned between the PIC24F XLP and PIC32MX families, and the first PIC32s to have the firm’s ‘core independent’ peripherals. Called PIC32MM, the family is aimed at IoT, consumer, industrial and motor control applications. Key figures are: sleep down to 500nA and a 4x4mm package. The core-independent peripherals selected include: ...

Looking on the bright side

Well, by a small margin, the people of the UK have voted to leave the EU. For weeks before the vote, Electronics Weekly was scouting around for people to go on the record about leaving or remaining. Plenty of people were prepared to talk about the benefits of remaining and, at the last count, nobody would go on the record ...

GPS chip adds inertial dead-reckoning for car tracking

ublox C93-M8E

u-blox of Switzerland has introduced a GPS receiver that works with inertial sensors to add dead-reckoning navigation when satellites signals are weak or before the receiver has locked-on. It requires an external MEMS inertial sensor and flash memory, and also works with other satellite navigation (GNSS) systems (list below). “EVA-M8E adapts automatically to installations anywhere within a vehicle. Dead-reckoning with ...

Enter the 1,000 core processor chip

KiloCore is a thousand core processor whose 621 million transistors execute 1.78 trillion instructions per second. Designed with an emphasis on low power operation by engineers at the University of California, the chip was fabricated by IBM on 32nm CMOS, and was revealed at the Symposium on VLSI Technology and Circuits in Honolulu. “To the best of our knowledge, it is the ...

Cree goes more horticultural

Cree XQ-E-Photo Red

Cree is going for horticulture lighting with the XQ-E Photo Red led. “XQ-E Photo Red LED is capable of providing very high levels of growth-promoting light wavelengths from a footprint that is less than one-third the size of its closest competitor with similar output,” claimed Cree. In the same way that lumens indicate not just the amount of light (which ...

China leads supercomputing with new machine

Sunway TaihuLight

China is still number 1 in world supercomputing, breaking its own record with an entirely new machine. Built using Chinese designed and built processors with a Chinese archetecture, Sunway TaihuLight achieves 93Pflop/s on the LINPACK benchmark. Developed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and installed at the National Supercomputing Center in Wuxi, the computer ...
