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 ...
Integrating Sphere plays the role in below three aspects. 1. Optical Receiver The measured light enters the sphere through the hole of integrating sphere. We set up one or two photo detectors on the inner wall such as selenium photovoltaic cells or photomultiplier tubes. The output light detector of the photo detector is proportional to the illuminance of the integrating sphere inner wall, which ...
Fair: Hong Kong International Lighting Fair 2013 (Autumn Edition) Date: 2013/10/27-2013/10/30 City: Hong Kong Exhibition Hall: Hong Kong Convention and Exhibition Centre Organizers: Hong Kong Trade Development Council Booth of Lisun Electronics: ED-A01 This is the second time we attend this fair. Hong Kong International Lighting Fair is held by Hong Kong Trade Development Council since 1999. The l...
Recently, there have a new that the China Consumer Association announcement computer failure excessive radiation harassment, that easy to affect the power grid equipment and cause computer crash. The main reason is that computer power terminal radiation harassment beyond the limits specified in the national standard, and this harassment may interfere with other electronic devices work properly, e...
OLED (Organic Light Emitting Display) is a new generation of flat panel display technology after LCD, LED, CRT and PDP (Plasma Display Panel). It has significant new industry characteristics. OLED is a new type of pure solid (CRT and PDP), which is a new type of pure solid (and LCD) with advantages of LCD and CRT. Besides, OLED has advantages of self luminous (no back light source), simple struct...
Surge generator anti-interference measurement is based on the international standard IEC 61000-4-5. SG61000-5_Surge Generator 1 Test objective The entire lightning stroke in the nature (namely the indirect thunder such as the lighting stroke between the clouds, or the lighting stroke happened to the adjacent objects) can induce the surge voltage and current in outdoor aerial. Besides, huge surge ...
Abstract: According to the particularity of LED luminous flux measurement, unique optimization is adopted in the design of the integrating sphere for LED measurement combined with the diffuse materials of high reflectivity, which makes the system stability and accuracy have great improvement. The experimental results show that the system stability and consistency is much higher than other commo...
Goniophotometer is mainly used for measuring photometric characteristics of luminaries and light source; that is luminaries laser photometric and colorimetric value distribution in different spatial directions. Goniophotometer should be placed to do test in dark room. Many customers concern the size of goniophotometer. According to Energy Star IESNA-LM-79 Clause 10, For measurement of luminous int...
