LISUN engineers often visit India to do installation and trainin. The service is recognized by the customers here. This customer is a local famous laboratory. This time they purchased 1 set LPCE-2 (LMS-9000B ) High Precision Spectroradiometer Integrating Sphere System from LISUN. Below is the picture of customer and our engineer after the installation and training: [caption id="attachment_10755" align="alignnone" width="2000"] Figure 1: LISUN LPCE-2 （LMS-9000B）High Precision Spectroradiometer Integrating Sphere System[/caption] Our main products are  Goniophotometer ,  Spectroradiometer ,  Integrating Sphere ,  LED Test Instruments ,  CFL Test Instruments ,  Photometer  and  Colorimeter ,  EMC & EMI Testing , Electronic Ballast Tester ,  Electrical Safety Testing ,  Environmental Test Chamber ,  Plug and Switch Testing ,  AC and DC Power Supply  and etc.

This is a large experimental institution in Colombia. They purchased ZRS-3H Glow-wire Test Apparatus , ZY-3 Needle Flame Test , TTC-1 Tracking Test Chamber , HVR-LS Horizontal Vertical Flame Tester and some other electrical safety testers from LISUN this time. They found LISUN through the website. The price of our equipment is higher than other companies’, but the materials used in our equipment are also better. We can provide on-site installation and training services. Through investigation, they cooperate with us finally. Our equipment and services also didn’t disappoint them.

Darkroom Design of goniophotometer As the most important part of the lighting test, the main function of the goniophotometer is to measure the absolute luminous intensity. At the same time, it can measure other parameters such as lumen and illuminance. Because of the different testing principle, compared with the integrating sphere spectroradiometer system , the device is more suitable for the measurement of the overall luminaire. Carrying the measurement with goniophotometer, the standard darkroom is needed. If the darkroom does not meet the requirements, it is likely to affect the final test results, which will lead to the deformation of distribution curve and the inaccurate results of lumen. And the final IES file will not meet the requirements, that will affect the final test results. According to the requirements of the test environment in LM-79 and CIE-70, this paper makes a brief introduction to the selection of darkroom: Temperature requirements: According to the requirements ...

It is according to IEC60695 and IEC60112 (GB4207), the Tracking Test Chamber TTC-1 is intended for determining the degree of protection against formation of conducting paths in solid insulating materials, due to the electric stress and electrolytic contamination of the surface. This method simulates tracking currents on insulation material by providing drops between electrodes. During the process of normal use, insulating material may be exposed to moisture and dirt, if conductive, may cause stress and fire hazard. [caption id="attachment_8935" align="alignnone" width="500"] TTC-1[/caption] Specification: • It applied with rectangle size of platinum electrode, each electrode can force to the sample is 1.0±0.05N • The testing voltage is 100~600V (48~60Hz) which can be adjustable • When the short-circuit current in the 1.0±0.1A, the voltage drops will be no more than 10% • During the testing, the short-circuit current is more than 0.5 A to keep 2 second...
