Goniophotometers are tools used for evaluating the luminous flux, otherwise also known as the brightness of various types of equipment. An LM-79 LM moving detector goniophotometer collects photometric data from different spherical locations. It then aids in ensuring the quality of the goods to be sold. It also supports the seller’s or the manufacturer’s standing in the market. The device’s p...
First of all, we need to know what lab is, because the color difference calculation of colorimeter is inseparable from the lab value; CIE in 1976 recommended CIE1976 L * a * b * color space, also known as CIELAB color space, which is mainly used for the representation and evaluation of hypoblend colors such as surface pigment industry. The following is the formula of color difference calculation m...
LISUN’s LSRF-3 Because the LSRF-3 is equipped with a Class A fast photometric probe, the sampling rate can reach 100kHz. It fully complies with BASIC, Energy Star V2.1, IEC-Pst, CA CEC, ASSIST, CIE SVM, IEEE Std 1789, and other standards. It is suitable for testing the flicker of LED lights and lamps, energy-saving lighting, and so on. According to EU directives 1494/2012, 2009/125/EC, EU201...
1. Introduction With the rapid development of modern science and technology, electronics, power electronics, and electrical equipment are more and more widely used. The high-density, wide-spectrum electromagnetic signals generated by them during operation fill the entire space, forming a complex electromagnetic environment. The complex electromagnetic environment requires electronic equipment and ...
1. Countermeasures and rectification measures for common problems in ESD immunity testing 1.1 The mechanism of electrostatic discharge formation and its harm to electronic products Static electricity is formed by the accumulation of positive and negative charges on two objects when two substances with different dielectric constants rub against each other. As far as the human body is concerned, the...
An integrating sphere is a sphere having a reflecting covering on the interior, as implied by the name. It is designed to have a light source inside of it, at which point it can calculate the overall flux output of the light. Hence 2pi and 4pi integrating spheres are one of its types. It amasses all the rays that leave the item and are reflected by the coating on the interior of the sphere. As it...
Defining Voltage dip generator NEMA MG1-16.48 defines voltage dip as the greatest voltage difference from the rated generator output voltage. Inrush currents at motor start-up or large block loads limit engine speed and lower excitation to the main field generate these dips. Because the causes and solutions for instantaneous voltage dips differ from those for block loads, they are measured and ana...
