A new calibration standard for solid-state lighting

Around 12% of electricity consumption in the world is used for lighting. More efficient systems have the potential of allowing Europe to save up to 34 TWh of electricity by 2030, reducing CO2 emissions by 7 million tonnes per year. Incandescent lights – where electricity flowing through a thin metal filament, such as tungsten, ...

New photometry standards for measurement of solid-state lighting products

Conventionally the calibration of photometric equipment was performed with tungsten filament standard lamps with the standard illuminant A spectrum, which was published by the International Commission on Illumination (CIE) in 1931 and was originally designed for use with incandescent lighting products. However, incandescent co...

Extending the range of European electrical power measurements

Conventionally, most electronic items in Europe operated at 50 Hz, matching the frequency of the domestic power supply. Recently, devices operating at higher frequencies have become prevalent in applications such as wireless power transfer, power converters for photovoltaics, and in industrial applications such as induction hea...

A new sensor for the liquid natural gas grid

Europe aims to be carbon-neutral by 2050 and use of Liquid Natural Gas (LNG) has been identified as an essential step during this energy transition. The amount of energy in LNG is proportional to the methane content, given by the ‘methane number’ (MN), with 100 MN being equivalent to 100 % methane. By measuring the LNG composit...

Ensuring confidence in liquid natural gas composition

Natural gas is a cleaner alternative fuel to other petrochemicals and its use is considered to be an essential step in making Europe carbon neutral by 2050. When extracted it is cooled below -160 ºC (~113 K) to form liquid natural gas (LNG) which reduces its volume 600 times, allowing it to be more easily transported and stored...

Ensuring the safety of wireless power transfer systems

Non-ionizing radiation in the radiofrequency range from 600 MHz to 300 GHz provides the basis for connectivity in mobile communication applications. Additionally, electromagnetic fields (EMFs) generated by inductively coupled coils at low frequencies (typically below 10 MHz) are widely used for contactless charging of household...
