• 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 manuck. 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.

  • 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.

  • Lisun engineers visited Barcelona recently, this visit was mainly to install the 3m Integrating Sphere Test System for the customer and provide training service.

  • This paper is a brief introduction and description for conducted immunity testing which based on IEC 61000-4-4 fast transient burst test, IEC 61000-4-5 lightning surge test, IEC 61000-4-11 voltage cycle drop test and IEC 61000-4-12 ring wave test.

  • In recent years, the CE marks are more and more widely used in the market of European economic area (Member states of the European Union and the European Free Trade association, except Switzerland). More customs of different countries set out the requirements of CE certification for imported products. Exporter will be in trouble as well as unnecessary loss if their shipping goods don’t have CE certified label.

  • Purpose of the test: to assess the ability of the material to prevent solids and liquids from entering the external shell.Detection range: electrical and electronic equipment, automotive aircraft and other parts IP level (waterproof and dustproof) definition IP waterproof and dustproof, refers to the protection level of electrical equipment, in accordance with its ability of preventing external objects intrusion, waterproof, moisture-proof and dustproof characteristics to be graded. The external objects…

  • Intelligent Lighting is the distributed lighting control system by using internet of things technology, wired/wireless communication technology, power line carrier communication technology, and embedded computer intelligent information process and energy-saving control technology to realize the intelligent control of lighting equipment. Shanghai launched a pilot project of the first road intelligent poles in Oct, 2015, which can achieve WIFI internet, reserve parking and call center personnel for video calls and other…

  • Lisun engineer visited Malaysia again at the end of December, 2016. This Malaysia visit mainly provides the retraining service for our customer. They purchased many equipment from Lisun, such as LSG-1800B High Precision Rotation Luminaire Goniophotometer Lisun will provide more after sales installation and training service to our customers and return the love to our customers with the most reasonable price and the best

  • Use Integrating Sphere Spectroradiometer System to test color parameters for light source and luminaries and use Goniophotometer System to test luminous intensity, which is the measurement for traditional light source and measurement. Compare with traditional light source, the optoelectronic properties of LED light source are more complex, traditional light source measurement methods and instruments are unable to fully meet the needs of the market. With the development of technology, new…

  • The International Electrotechnical Commission (IEC) has published IEC 61000-4-5:2014, “Electromagnetic Compatibility (EMC) – Part 4-5: Testing and Measurement Techniques – Surge Immunity Test.” “IEC 61000-4-5:2014 relates to the immunity requirements, test methods and range of recommended test levels for equipment with regard to unidirectional surges caused by over-voltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed…

  • After the Light India lighting exhibition in New Delhi India, Lisun engineers went to visit our local customers, to do installation & training of LED lighting photometric, colorimetric and electrical parameters test instruments. This customer is a famous LED lighting luminaires manufacturer who has branch offices in India and China. After months of communication and discussion, they decided to purchase Lisun newest economical model LPCE-3 CCD Spectroradiometer Integrating Sphere Compact…

  • Many customers need aging LED lamps, but do not have a clear concept of aging test and life test. Aging test usually use aging test racks. What is aging test rack? Aging rack is dedicated to simulate the products in real conditions involved in the use of various factors on the aging of the product conditions to strengthen the process of the corresponding conditions. Why we need aging test? Electronic products,…
