Having a surge generator ensures you have enough electricity in case of emergencies or power disruptions. The issue develops when your generator stops working properly. Thankfully, power surge generators are quite communicative and will let you know if something is wrong and needs repair. Why does a generator surge? Inappropriate fuel use, poor maintenance, age, a failing capacitor, or other ccomp...
Photometers and spectrophotometers instruments are well-suited and well-established for measuring moisture, oil/fat, and other easily distinguishable parameters in a wide range of applications. spectrophotometer derived from these photometers. Photometers are usually used to measure parameters at certain wavelengths where the parameter absorbs light, such as 1.94 microns for water and 1.72 micron...
Radiometry professionals may be familiar with the theories of light and color measurement; the equipment used to detect light and color. The instrument for such calculations includes radiometer, spectrometer and spectroradiometer. However, all three devices can measure light and energy. Therefore, the capabilities, intended uses, and applications of radiometers, spectrometers and spectroradiometer...
A goniophotometer is a device used to determine the amount of light emitted by an item at various angles. The usage of goniophotometers has increased in recent years due to the advent of LED light sources, which are predominantly directed light sources with a non-homogeneous spatial distribution of light. If a light source’s distribution of light is homogenous, it is referred to as a Lambert...
The integrating sphere is a rounded device having a reflecting covering on its interior. It usually contains a light source and measures its total flux output. It gathers all the rays emitted by the item and is reflected by its reflecting covering. The integrating sphere efficiently integrates the measured light output from a source. Integrating sphere price may vary from company to company. What ...
Goniophotometer definition: Goniophotometer is used to measure the spatial light intensity distribution and various photometric parameters of LED lamps/street lamps, indoor and outdoor lighting lamps. Including measurement: Luminous Intensity Data, Luminous Intensity Distribution, Zonal Luminous Flux, Luminaries Efficiency,Luminance Distribution,Coefficient Of Utilization, Luminance Limitation Cur...
RoHS is a mandatory standard established by EU legislation. Its full name is “Restriction of Hazardous Substances” (Restriction of Hazardous Substances), which was published on 1st, July , 2006. It has been officially implemented. It is mainly used to standardize the material and process standards of electronic and electrical products to make it more conducive to human health and envir...
According to CIE127, EN13032-1 and LM-79-19, there two ways to test lighting lamps for photometric parameters: Spectroradiometer & Integrating Sphere and Goniophotometer System. What’s difference between them? Here we give you a brief introduction. 1. What’s the test principle difference between Spectroradiometer & Integrating Sphere VS Goniophotometer Test? The principle of the Spectr...
Limits for harmonic current emissions(EN/IEC 61000-3-2:2019) was promulgated on 1st, September, 2019. The new standard is applicable to the European Union and related countries and regions. This standard will be enforced on March 1, 2022 and will replace EN IEC 61000-3-2:2014. The new standard restructures and narrates some chapters, redefines equipment categories, and updates the measurement requ...
