LED Tester | Christmas Light Tester - LISUN

LISUN engineers continue to visit countries around the world to install and train for our our customers. In this month, there is an engineer visit New Zealand, and returned yesterday. The customer purchased a LSG-1800BCCD Goniospectroradiometer and a LMS-6000 Portable CCD Spectroradiometer from LISUN. Our engineer communicate with customers through English in the whole process of training. In the end, our customer recognized our products and services. Then share a few photos: 1: LSG-1800BCCD Goniospectroradiometer has been installed.

The International Electrotechnical Commission (IEC) has issued IEC 61000-4-2 Ed. 2.0 (2008-12) entitled “Electromagnetic compatibility (EMC) – Part 4-2: Testing and measurement techniques – Electrostatic discharge immunity test.” This standard relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, or from personnel to adjacent objects. Additionally it defines ranges of test levels that relate to different environmental and installation conditions and establishes test procedures. The object of this standard is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. It also lists EDS that may occur from personnel to objects near vital equipment. It defines typical waveform of the discharge current, range of test levels, test equipment, test setup, test proce...

Driver is the most important component of LED luminaire, its quality is directly related to the performance and quality of the luminaire. As the LED lighting manufacturers and importers’ production and procurement are in large quantities, the traditional LED driver tester has been unable to meet the demand. As per the requirement of customers, Lisun developed the LEDRACK-100W192P LED Aging Rack. It is applied to the production line for the finished products testing. This system fully complies with the requirements of IEC62384, GB24825-2009 and other relative standards. Please refer the picture below. LEDRACK-100W192P LED Aging Rack The LED Driver Aging Rack includes three parts: LED Driver Aging Rack, Aging Control System (includes PC & software) and LED Load Module. The specification is as following. Application range: LED driver and multi channel driver power aging. It has equipped with computer operation and monitor system. The working condition can be set by...

The Spectrometer & Integrating Sphere System or Photometer & Integrating Sphere System, there’s have two important parts: one is measuring and analysis; another is assistant part which providing testing environmental. Here we will discuss the assistant part, we knew that the integrating sphere spherical aggregates, the inner wall of integrating sphere is coated with a highly reflective coating material to the effect of light refraction. Here to two points: First, according to the lamp size, how choose suitable integrating sphere; Second, according to the types of lamp, how to choose right test method. More details refer below: First, according to the lamp size, how choose suitable integrating sphere. Normally, the diameter of integrating sphere from several centimeters to several meters. In the lighting industry, the size of integrating sphere from 0.3 meter to 4 meters. The 0.3 meter integrating sphere mainly focus on special test, like laser. There can divide several par...

The definition of goniophotometer is for measuring light lamps and light performance, that's lamp light source luminosity, color values in different spatial directions distribution, and export to IES files applying on the lighting design software DiaLux. The CIE121-1996 and IES-LM-79-08 standard’s are mentioned the types of goniophotometer, the CIE121-1996 mentioned two type goniophotometer:: one is moving mirror goniophotometer or moving detector goniophotometer; another is Rotation Luminaires Goniophotometer. The IESNA-LM-79 Clause 9.3.1 have clear recommended to use Type C Goniophotometer that’s moving mirror goniophotometer or moving detector goniophotometer. In practice, the solution and choose of goniophotometer are different. First we need explain the moving detector/mirror goniophotometer and rotation luminaires goniophotometer: moving detector goniophotometer which means the measured light's test position keep stable, the mirror reflection the light source from meas...

Glow wire test is to test the stability of electrical and electronic products during working. And the hot wire itself is the resistance wire ring with fixed size. When doing test, the wire ring should be heated up to the specified temperature by electricity, so that the time when the top of the wire reached the sample can meet the time standard required, then observe and measure its state. The test range depends on the specific test procedures.   When do the test for the determination of the burning of hot wire (GWFI) in a solid electrical insulation material or other solid materials test sample, there is a detailed requirement for the hot wire test method in standard GB/T 5169. Test results can be used for relative comparison of the performance of the above various materials, namely, the ability of the flame extinguished when remove the electricity heated hot wire; and the ability to not produce burning or glowing particles for the beneath bedding layers and packaging paper of the...

With LED development, the traditional fluorescent tubes in the market are gradually being replaced by LED tubes. Currently LED tubes can be divided into three categories: Type A tube: This lamp can replace the fluorescent tube directly without modification; Type B tube: The power supply of this lamp is built-in LED tube, which can connect with city electricity; Type C tube: Use external power supply to provide power for LED tube. The Type A tube enters North America market, which needs to meet the standard UL1993 UL Standard for Safety Self-Ballasted Lamps and Lamp Adapters. The update protocol requires that test should adopt constant current power supply method to instead of constant voltage power supply method and cancel the original current limit. Lisun HCS-109A Adjustable LED High Frequency Reference Ballast is according to the latest requirements of UL1993 standard. It adopts 25KHZ high frequency constant current source power supply. HCS-109A is used to do input test, temperature...

LISUN engineer visited Peru customer in May, its really a pretty company, they bought a LSG-1800B Goniophotometer from LISUN, and we believe that we can achieve a long-term cooperation in the future. The first day our engineer arrived here, he came to the darkroom to install the equipment with the staff together. The second day, they start the training, LISUN engineer trained the operation for the LSG-1800B detailed, and solved questions for our customer. Its really a happy training. Here we share several pictures: Picture 1: LISUN engineer installing the equipment with staff [caption id="attachment_7290" align="alignnone" width="800"] LISUN engineer visit Peru to Install and Train the LSG-1800B Goniophotometer in May[/caption] Picture 2: LISUN engineer installing the equipment with staff [caption id="attachment_7291" align="alignnone" width="800"] LISUN engineer visit Peru to Install and Train the LSG-1800B Goniophotometer ...

For IP grade test, we know the regular level IPX1~IPX8, today we will introduce the IPX9K grade test.
