A LM-79 goniophotometer is an instrument for measuring the light reflected off an object at various viewing angles. It is somewhat considered like integrating sphere spectrophotometer. Most recently used LED-light sources are usually directed light sources with a non-uniform spatial distribution of light, necessitating the employment of goniophotometers. A Lambertian source is one whose light is d...
It may replicate damage caused by the sun, heat, moisture, and spray in an accelerated weathering xenon lamp aging chamber. This chamber adopts xenon arc lamp. Textiles, dyes, leather, plastics, paints, coatings, automobile interior components, electronics, color construction materials, and more all benefit from weather meter xenon weathering test chambers. To put it through its paces in the weath...
The human eye cannot correctly represent color in quantity, but we can use colorimeter and spectrophotometers to measure color, which is very simple. The position relationship between the illumination source, the measured sample and the sensor is the illumination observation geometric conditions in color measurement, referred to as geometric conditions. CIE15:2004 recommends ten geometric conditio...
One kind of testing chamber used for aging is the UV aging test chamber. Another name for the UV weathering chamber (or UV aging chamber) is the weather accelerated aging test chamber. At the chosen temperature, it replicates ultraviolet radiation and does UV tests. It is possible to age non-metallic materials in the UV aging test chamber using natural and artificial light sources. The source con...
Tests are conducted in a waterproof test chamber to determine how well a product’s enclosure protects its contents from the elements. It is also a rain test chamber. An IP number represents the degree of protection against water infiltration. Every single one of LISUN’s test chambers is built to the exacting requirements set out by the IEC 60529 (IP Code standard) and other similar bod...
JL-X waterproof test machine is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, IEC60598, IEC60335 and IEC 60034-5, GB/T-2423.2, GB4208, GB7000.1. The JL-X includes the following test grades: IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7 and IPX8 (Refer to page 51 of IEC60529). It is widely used in the authentication test organization fo...
The integrating sphere is a sphere having a reflective covering on the interior. It is used as lead light test equipment. Typically, one would place a light source inside it to measure the source’s overall flux output. All the beams emitted by the item are gathered together after being reflected off the inner reflecting covering of the spherical. Named because of how well it integrates the m...
The three elements of color: brightness, hue, and color saturation. In the LCH color space, L is brightness, C is saturation, and H is hue. In the RGB color space, R is red, G is green, and B is blue. In the LAB color space, L stands for brightness; A indicates the red-green bias, A represents the red direction, and A is negative represents the green direction; b indicates yellow-blue bias, b is p...
To ensure their goods can withstand even the most extreme circumstances, manufacturers often use a humidity chamber, a special device that simulates a variety of humid settings. It is also called a high and low-temperature test chamber. They may also observe the effects of humidity changes on their goods. Product parameters may be tested under extreme circumstances by manufacturers. Humidity chamb...
