Photometric tests and measurements of LED lamps and sources may be challenging because they come in many different shapes and sizes. The position of the photometric center is located in different spot for each luminaire. by Miko Przybyla I GL Optic The photometric center of the lamp or luminaire is the point, which must be [...]

A visual assessment is not enough to ensure the quality of illuminated LED or OLED control panels & indicators components. We need to use luminance measuring devices in order to verify the luminance level, i.e. the perceived brightness of these elements. by Jacek Dylak and Miko Przybyla I GL Optic Conventional devices for measuring luminance [...]

Photometric measurements are crucial in quality testing and new product development. Operating a goniometric system, for LED light measurement may seem complicated. However its use help control the whole testing process, save time and money, while also builds up important knowledge inside the company, that will benefit future products. by Miko Przybyla I GL Optic [...]

The revised regulation of the European Commission on ecodesign for light sources introduces new requirements for light flicker indicators, including PstLM, which determines the resistance of the light source power supply system to network disturbances. PstLM stands for Short Term Perceptibility for light modulation. The new requirements enter into force in September 2021 and will [...]

Photometry is the science of light measurement, which takes into account how the human eye perceive its brightness. It measures only the visible spectral range, where human eyes are sensitive. Photometric measurements are crucial in quality testing and new product development, starting with single LEDs through modules and lamps up to luminaires used in buildings [...]

In professional industries, such as the automotive or electronics industries, there are no detailed recommendations or instructions on how to measure the parameters of high power LEDs. Therefore, the recommendations of general lighting standards are applied and industry-specific measurement methods are developed. by Miko Przybyla | GL Optic Maintaining the right temperature Technical datasheets for [...]

Road lighting has a particular impact on improving road safety, and it is the luminance measurement that determines the level of “brightness” of the road surface observed by the driver. In this article we will discuss how to use an Imaging Luminance Measuring Device for road lighting verification in accordance with current regulations. by Miko [...]

A year from now, at the end of 2021, the new Commission Regulation EU 2019 2020 (Ecodesign) enters into force. The specific requirements for electrical equipment including LED light sources are changing. In addition to the new energy efficiency classes, completely new minimum requirements for flicker and the so-called stroboscopic effect are introduced. Lamp manufacturers, [...]

I want to explain the issue of UV light before we start. UV radiation can’t be used for skin disinfection because it will damage the molecules and can cause serious health problems. Secondly UV light is not the best term for what we are going to discuss here. The light refers to the visual part [...]
