LED Tester | Christmas Light Tester - LISUN

Lisun engineer visited Bulgaria in the middle of MAY, 2017. In May, our engineer was too busy because there were many customers who purchased Lisun instruments to need installing and training. We already have added two new clients in Bulgaria in MAY. So our engineer visited Bulgaria to installing and training for the two clients. The clients had purchase LSG-1700B Rotation Luminaire Goniophotometer, LPCE-2 Spetroradiometer Sphere System, LSRF-2 Lamp Start, Run-up Time and Flicker Test etc. In the visiting trip, Our engineer got feedbacks from the clients that they were satisfied with Lisun Products, and our engineer depended on their professional technical and fluently English to earned plaudits from our customer sides. Here are some picture from our clients sides as below: Figure 1: LPCE-2 Spetroradiometer Sphere System Figure 2: LSG-1700B Rotation Luminaire Goniophotometer Figure 3: LSG-1700B Rotation Luminaire Goniophotometer Figure 4: Integrating Sphere with Holder Base

The quality of LED driver will influence the life of LED lamp directly. Therefore, we need to control the quality of LED driver strictly. According to IEC62384-2011 and GB/T 24825-2009 DC OR AC SUPPLIED ELECTRONIC CONTROL GEAR FOR LED MODULES – PERFORMANCE REQUIREMENTS. The control gear shall be subjected to a temperature cycling shock test and a supply voltage switching test as follows: a. Temperature cycling shock test The non-energised control gear shall be shored firstly at -10C or if the control gear is marked with a lower value, at that value for 1h. The control gear is then moved into a cabinet having a temperature of Tc and stored for 1h. Five such temperature cycles shall be carried out. b. Supply voltage switching test At rated supply voltage the control gear shall be switched on and off for 30s. The cycling shall be repeated 200 times with no load and 800 times with maximum load conditions. LED modules failing during this test shall be replaced immediately. At the end o...

This Algeria client built a new big lab not long ago. They ordered all the test instruments from Lisun Group. Lisun sent two engineers to help them for the installation and training. Here are some photos to share with you.

High/Low temperature & humidity test chamber is used to simulate a actual temperature and humidity environment which it may caused any influence for surrounding objects，due to electronic products widely application in various occasions, in order to design better product which meet relevant environmental standards, the temperature and humidity test has become an necessary test items, and high/low temperature and humidity test chamber widely used in many different industries such as aerospace product, electronic instrumentation, materials, electronic products and various electronic components, this environmental test chamber used to checking working performance of DUT in high temperature, low temperature or hot and humid environment. This article focuses on discussion environmental climatic chamber application on the LED lighting industry application. Lisun Electronics (Shanghai) Co., Ltd is one of best LED lighting test equipment supplier, our products involved photometric, co...

LISUN engineer visit Croatia to install and train goniophotometer. A customer in Croatia bought a LSG-1800BCCD goniophotometer in LISUN. As soon as they received the goniophotometer in May, we arranged engineer to install and train to there. And LISUN is praised “Nice Service” here. The installation and training went very well: In the whole process of the installation, LISUN engineer communicated with customers through English （All members in LISUN can speak English fluently）. Firstly, according to the English manual provided by LISUN, the engineer and staff completed the installation of the test system together. And then, LISUN engineer trained them how to operate the test equipment patiently. Lastly, LISUN engineer practiced the test operation with staff together. Here we share several pictures with you:   Picture 1: Engineers and customers in the lab Picture 2: Engineers and customers in the office Lisun Group is Lead in CFL and LED Test Instruments. Ou...

Europe Installation and Training Mission in November Lisun engineer visited four Europe customers this time, two Spain customers, one UK customer and one Germany customer. The first Spain customer purchased EMI-9KB EMI Receiver System, LSG-1800B High Precision Rotation Luminaires Goniophotometer and LPCE-2(LMS-9000A) High Precision CCD Spectroradiometer & IS-2.0MT Constant Temperature Integrating Sphere System.
