The LED stroboscopic effect actually have two concepts: One is strobe which mean the depth of light flux fluctuations, the more violent fluctuation, the depth of strobe more lager. Second is stroboscopic effect which mean the human visual produce negative effects of electric light flicker, the more violent fluctuation, the negative effects more lager, the damage will be more bad. The flicker and s...
Under the effect of high temperatures, the structural characteristics of non-metallic materials, insulation materials will change greatly, which manifests itself softened or melted. Ball pressure test is used to test the heat resistance of non-metallic materials and insulating materials. It indicates the requirements of the ball pressure test in IEC60695, UL, IEC884-1, GB / T5169.21-2006, GB4706.1...
Due to the demand of Lisun market business expand, and kind invitation from AUTOMATE PROCESS CONTROL, on 9:00am April 23, 2016, Lisun & AUTOMATE organized customer technical seminars in a big hotel at Mumbai, in addition to Lisun’s old and new customers, there are many other technical engineers, who were LED manufacturers, laboratory personnel etc, and on-site customer actively speak, the fo...
IEC/EN62471 is the European Union’s testing standards for laser products (including LED). IEC/EN 62471 is designed to evaluate the optical radiation hazards associated with different lamps and lamp systems. And it is also used to replace the IEC/EN60825 standards in the requirements of the LED product energy level. It increased the requirements of the optical biology, including radiation intensi...
Electrical Ballast is one kind of the ballasts; it is the electronic equipment which adopts electronic technology to drive the electrical light source to produce light. Modern Fluorescent lamps increase to use electronic ballast, compact and small, even can integrate electrical ballast and lamp tube, at the same time, electrical ballast usually can be compatible with starter function, thus it can ...
Lisun will come with professional technical team to attend 2016 Germany Frankfurt Lighting Fair( Light + Building) dated on 13th Mach ~18th March, 2016. This time we will show full set of colorimetric & photometric test system, EMI/EMC testers and LED Power Driver tester and so on. Welcome to visit us at Hall 10.2 Booth C60C. Meanwhile, we will visit local customers and other Europe customers ...
UV aging test chamber is suitable for the aging test of non-metallic materials resistant to sunlight and artificial light. Light source adopts eight UV fluorescent lamps that rated power is 400W as a light source. UV fluorescent tubes are distributed on sides of chamber, every side has four (There are UVA-340 and UVB-313 light source for users to select the configuration). UV aging test chamber is...
The CV model load is the basic of the LED power supply test. CV is constant voltage, but the load is only the current load equipment, itself does not provide constant voltage, therefore, the so-called CV is just through the voltage negative feedback circuit, to servo the change of LED power supply output current, to make the LED output capacitor charge balance, thus achieve the purpose of constant...
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 tes...
