LISUN ENGINEER VISIT AT BULGARIA IN MAY 2017

Image
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

LED Driver Aging Rack meets the Standard IEC62384-2011

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...

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...

LMS-6000 Series Function Contrast

Lisun LMS-6000 Portable color spectroradiometer is the only one used telephoto optical system in portable spectrometer illuminance meter, spectral resolution is 0.2nm, which can measure LED wide spectral light source and also can measure CFL, HID narrow spectral light source.   It can be calibrated automatically by itself. Do not worry that the dark background changed affects the measurement results. Minimum integration time can be 50us, which can measure stronger optical signal. With automatic zero calibration and zero compensation technology, the maximum integration time can be longer and it can measure weaker optical signal.   Lisun launches two models currently: LMS-6000 and LMS-6000P.   LMS-6000 can measure the light wavelength range from 380 to 780nm, illuminance E(lx), Candlelight E(fe), CCT(K), Duv, Coordinate x,y, Coordinate u,v, Coordinate u’,v’, SDCM, CRI, R1~R15, Irradiance Ee(W/m2), S/P, Dominant(nm), purity(%), half width(nm), Peak wavelength(nm)...

What is TM-30?

What is TM30? IES TM-30-15 is a document approved by the Illuminating Engineering Society (IES) that describes a method for evaluating light source color rendition. The method encompasses several individual measures and graphics that complement one another and provide a comprehensive characterization of how the light will affect the color appearance of objects. The three highest-level components of the system are the Fidelity Index (Rf), Gamut Index (Rg), and Color Vector Graphic. Why was TM-30 developed? The existing color rendering metric widely used in the lighting industry, the International Commission on Illumination’s (CIE’s) General Color Rendering Index Ra (commonly called CRI), was developed more than 50 years ago, and has been unchanged in the last 40. Although it has served a vital purpose, its limitations are widely recognized, including by the CIE. The CIE has been working on a replacement or alternative for more than 25 years, and many researchers have develope...
