If you belong to the engineering field and, running an electrical industry then there is might possibility you have the experience of finding LED testing devices to measure the function of LEDs through different aspects. So, if your answer is yes, then there is no need to worry for you we introduce to you two gadgets that will help you with LED lamp testing by using the Goniophotometer and integrated sphere.

A brief introduction to goniophotometer

The goniophotometer introduced by the LISUN is C-type which fully meets with the requirements of LM-79 (Institutes of America related to light) and LM-80-08 commission delegation regulation. LISUN LSG-6000 type C goniophotometer upgraded from the older version and its all features have compliance with the LM-79-19 standard.

A brief introduction to Integrated sphere systems

The integrated sphere is also named ahollow sphere that contains two pieces and these can be opened widely. You can choose the lumen sphere according to your need but if you move towards the LISUN it is not producing traditional models but the models produced with a high reflectance surface and are modified from the outside.


The main purpose of using a goniophotometer is to measuring of the light distribution from objects at different angles. The light can be measured from the near and apart point also but the C-type goniophotometer can specifically measure the light in between 5m to 30m (far point). Including the LED it can measure all types of lighting sources such as indoor lights, outdoor luminaires, street lights, floodlights and much more.

The basic purpose of using the integrated sphere includes the measurement of the light lumen, chromaticity of light, wavelength, and peak wavelength from the light source. These are the measuring features that help in the manufacturing, detection and testing of LED lamps in a good way.


Along with the big mirror, the near field detector moves in a line. In this way, the big mirror and far-field move synchronized way. Heat will not affect during the testing and the detector will sense the light from the luminaries

The amazing feature includes the goniophotometer launched by LISUN present in the parts the rotatory motor insert in it is made from Japan and the angle decoder system insert in it is made from Germany. The high-quality spare parts used in the goniophotometer help them to rotate stable with high accuracy and you feel comfortable during the running and stoppage of the goniophotometer. The working principle used is according to IESNA and CIE and also meets the standard of LM-80, LM-75, and much more. There is a special alignment device with a laser line for convenient use of the goniophotometer.


The painting material of the sphere on the integration sphere is of high quality. BAso4 (Barium sulfate) is used in the painting material of the integrated sphere which is highly resistive and durable, this feature is present in the good models and integrated sphere launched by LISUN. It has fine diffusion with multiple reflectance all kinds of power systems are built-in. Such as two photo detector ports, optical fiber, power cable, and power socket these all features are present in the integrated sphere established through the LISUN. A built-in cross laser is a feature that helps to install the standard lamp and all the results are connected to the software that is operated in the computer.


This article is compiled to introduce you to the goniophotometer and integrated sphere their introduction, the purpose of usage, and special features that are present in the LISUN products. But, the basic purpose of both instruments is the same: to test the LED lights and make them better for use. In order to get more information related to the testing instruments, you can visit the official website of the LISUN.
