As we all know, UV actually includes 3 bands, from 320nm~400nm, UV-A of low frequency and long wave to 280nm~320nm, UV-B of medium frequency and medium wave, and then to 100nm~280nm, UV-C of high frequency and short wave. Application of UV Light in Different Bands As one of the LED market segments, UV LED can be said to be in its infancy and is expected to have high growth in the future. Correspon...
EDX-2 RoHS Testing Equipment Introduction EU Legislation has established a mandatory standard known as RoHS. It stands for “Restriction of Hazardous Substances” (Restriction of Hazardous Substances). We have formally implemented this standard since July 1, 2006. It is mainly used to regulate the materials and process the means of electrical and other electronic products. RoHS Test Equipment Th...
What is a ball pressure test? Under the action of high temperature, the structural properties of non-metallic materials and insulating materials will change greatly, and this change is usually manifested as material softening or melting. The IEC ball pressure test is used to test the heat resistance of non-metallic materials and insulating materials. In the safety standards for products such as pl...
What is a power surge? Power surges are abnormally high voltage spikes occurring on the AC power. Their short duration, high energy events indicate that they are both very fast and very large. Several conditions affect the quality of power. These conditions include sags, brownouts, blackouts, swell lines, noise surges, temporary over voltages, and sustained over voltages. Power surges are the most...
Photometry LISUN is an independent lighting and optical test laboratory for testing LEDs, lamps, luminaries, displays, signs, and vehicle lighting. Photometry is the modern science used for the measurement of visible light regarding its perceived vision brightness to the human vision. The SI unit of photometry is lumen (lm). The two laws used in photometry are inverse square and cosine laws. The i...
Introduction The photoreceptor cells on the retina of the human eye are divided into two types: rod-shaped (circle) cells and cone-shaped (round) cells. The former has high sensitivity and is used to sense low light and distinguish light and dark, but it has no color perception. Cone-shaped (round) cells have low sensitivity and are used to sense strong light and have color perception. The sensiti...

Introduction A spectroradiometer is an instrument ( a light measuring tool ) used to measure the wavelength and amplitude of the light emitted from the light source. Spectrometers are used to discriminate the wavelength based on the position at which the light hits the detector array, allowing the full spectrum to obtain a single acquisition. A colorimeter is defined as ”an instrument that i...
