USA Environmental Protection Agency(EPA) and Department of Energy(DOE) successively released Energy Star and Lighting Facts Standards for LED Luminaires/Bulb from 2010, which makes relevant industry persons have LED Lighting products standard to follow. At present, international LED large manufacturers for LED product Life evaluation and product specification are also on this basis. That is to sa...
The equipment for electrical safety performance test is in rapid development of modern science technology; all kinds of electrical and electronic equipment are into all fields of social life and become an important symbol of social civilization and progress. All kinds of electrical appliances and electronic equipment are used in both urban and rural areas and have rapid popularization, which br...
The best way to test electric and electronic products’ fire hazard, is truly to reproduce the actual existence of conditions, but it is impossible in the most cases. Therefore, according to the current situation, it’s better to simulate the actual effects for electric and electronic products’ fire hazard test. Needle Flame Test, is used to simulate the fault conditions generated by a small f...
Due to the quality of LED Driver directly determines the life of the LED lamp, now more and more customers pay great attention to LED Driver testing. In order to meet IEC 62384:2006 and GB/T 24825-2009 standards, Lisun designed the following several products: 1. ATE-2 LED Driver Automatic Test System It is suitable for LED lighting companies who are very demanding on LED driver. It can test the i...
Light object by the lighting source and standard source(Generally, sunlight is as the standard source), the degree consistent with color is the color fidelity degree, represented by Ra, the maximum value is 100. As an important index to measure the quality of lighting, Color Rendition Index (CRI) is related to the color reduction degree of lamp to object itself, CRI is higher, the color of object ...
Due to the LED luminaries such as LED street luminaries developed, to do 4π geometry testing, it is hard to be hold in the traditional integrating sphere design. To solve this problem, Lisun design a new kind of sphere. New Integrating Sphere Design 1. The hold base can bear max 20kg, it can expanding to test all lamps such as E27/E40, all tubes such as T5/T8/T12, and all kinds of lumina...
LED testing equipment mainly has Goniophotometer and Integrating Sphere Spectroradiometer System. Goniophotometer is used for light intensity distribution measurement; integrating sphere spectroradiometer system is used for flux and colorimetric measurement. So how maintain these lighting test equipments? Integrating Sphere maintenance: Inspect and clean the external of integrating sphere, such...
LISN is short for Line Impedance Stabilization Network. LISN is important assistant equipment for EMC test in the power system. It can isolate the disturbance from power grid, provide stability test impedance and pay the role of filtering wave. LISN net is based on filter theory. When spectrum interference is different from the useful signal band, filter out the unwanted signal by filter. Proper d...
A lamp is composed of one or more luminous light sources with a shell (namely lamps, for example, some down lamp can be installed in one tube or two tubes). The light source and lamps can be separated. Nominal flux of each light source: it refers to the Nominal luminous flux of each light source installed in the Test lamps. It is expressed as φNominal Test flux of each light source: it refers to ...
