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...
