The ipx9k High Temperature Pressure Jet Waterproof Test Chamber is characterized by a waterproof grade of 9, indicating high temperature and high pressure water spraying, and spraying high temperature and high pressure water in various directions of the shell for water spraying test. In addition, k represents a function of pressurization, and under such strict conditions, its water pressure will become stronger. The ipx9 is currently a high level of waterproof protection. The IPx9 High Temperature Pressure Jet Waterproof Test Chamber is also widely used in fields such as LED lighting fixtures, display screens, household appliances industry, automobiles, and automotive accessories. At the same time, all dust and waterproof equipment can be customized according to user needs. The ipx9k High Temperature Pressure Jet Waterproof Test Chamber has four different vertical spray angles, namely 0 °, 30 °, 60 °, and 90 °, and the water pressure can reach 8000 to 10000 Kpa; Moreover, its testing r...

Photometric lumen test for LED spot light with LISUN integrating sphere

The quantity of luminous flux (lumens) that is produced by an LED spot light may be evaluated with the use of a kind of measurement that is referred to as a photometric lumen test. An instrument called a photometer, which is sometimes referred to as a luminometer, is used in the process of carrying out the examination. This piece of equipment measures the amount of light that is emitted by the LED light and evaluates it in comparison to the output of a more traditional source of lighting. In the majority of instances, the photometer consists of a detector that is either a photodiode or a photomultiplier tube. This detector measures light. This detector is in charge of collecting the light that is produced by the LED spot light and transforming it into an electrical signal. Its responsibilities include these two tasks. After that, the signal is examined, and the results of that processing are used to calculate the luminous flux that is being emitted by the LED light. Afterwards, th...

How the LISUN goniophotometer can help you measure light intensity and distribution

-
Image
An automotive goniophotometer is a device that can measure the light that is emitted by a light source when seen from varying angles. The phrase "goniophotometer" originates from the combination of the terms "goniometer," which measures angles, and "photometer," which measures light. The angle and the amount of light are measured by the goniophotometer's apparatus, which is the same equipment. A goniophotometer is an instrument that measures the distribution and the photometric qualities of light produced from a light source at various angles. The goniophotometer can measure the brightness (cd/m2), the light intensity flux , and the light intensity (candela). Using the data on the amount of light, it is feasible to compute the lumen value of a light source. The measurements of light's intensity were measured at a variety of angles relative to the source of the light. Mathematical computations are used to determine total light output, measure...
