Glassification could stabilise Perovskite light emitters

Lead (Pb) halide perovskites, known for fledgling solar cell technology, can also emit light. The materials are generally unstable in the moisture of the atmosphere, deteriorating over hours or days. But researchers in Australia have maintained ~80% of emission despite 10,000 hours of water immersion. Although this was a photo-luminescence proof-of-concept – emitting light when ...

Updated lighting guide for partially-sighted makes good reading for all

The Thomas Pocklington Trust has once again updated it guide for lighting spaces in which partially-sighted people live, and has broadened its appeal to beyond its original intended audience. “Lighting makes such a difference for partially sighted people, often enabling them to maintain their independence,” the Trust told Electronics Weekly. Now at issue 3, ‘Lighting in ...

Vandal-resistant push button needs less space behind the panel

C&K has launched anti-vandal push buttons that need less space at the rear compared with its earlier 22mm offering. The ATPS22 series has a shorter bushing than its ATP19 or 22 series, and comes in solder lug or wire terminated versions. The solder version extends 21.15mm from the front of the panel to the tip ...

Panel potentiometers are stiffer to resist accidental rotation

Vishay has introduced panel potentiometers that are stiffer to rotate, to reduce the chances of operation accidentally or though shock or vibration. Behind the panel, the bodies are 12.5 x 12.5mm, and they are modular, allowing up to seven potentiometers to be stacked on the back of a single shaft. Various switch modules can be ...

Batwing distribution for horticultural leds

Osram has introduced horticulturall lighting leds with a ‘batwing’ output distribution. Implemented in Oslon Square Batwing, the distribution comes purely from a primry lens built into the pacakge. “Current LED fixtures often have a lambertian primary lens and no secondary optic, or a simple glass cover, which lead to hotspots with high concentration of light ...

UK made: Raspberry Pi Zero W gets 5x computing power in version 2

Raspberry Pi has used system-in-package technology to boost processing power in its tiny Zero with a quad-core processor. Not to be confused with the similar-looking Compute Modules, the Zero is a full computer with an HDMI connector on-board. “Where our larger products have grown steadily more powerful over the years, we’ve never found a way ...

Current-to-bits converter fast enough for optical reflectometry

ADA4355 from Analog Devices is a current-input digital-output converter works with pulses down to 10ns for time-of-flight measurements using photo diodes. In a 12 x 6mm BGA package, the IC is actually a hybrid module combining transimpedance amplifier, analogue low-pass filter and 14bit 125Msample/s ADC converter. The output is through two serial LVDS (low-voltage differential signalling) lanes at ...
