LISUN GDJS seriesHigh and Low Constant temperature and humidity chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2). It is used to test the CFL/LED which meets IES LM-80-08, electricity products, electronic components, material and so on. There is some other manufacturers in China also produce High and Low Temperature Humidity Chamber, and LISUN VS espec temperature ...
Waterproof testing grade reflects the ability of moisture-proof of products. Especially for outdoor activities, it is unavoidable to be in the harsh environment of high humidity. The sealing and water-proof ability of the instrument is very important to ensure the safe of operation and life of the instrument. At present, there are many manufacturers producing waterproofing test equipment ...
In optical testing, the measurement of luminous flux and color temperature are essential. There are two test equipment for the measurement: Integrating Sphere Testing System and Goniophotometer. Here we give you a brief introduction to the difference of goniophotometer vs integrating sphere: 1. Integrating Sphere & Spectroradiometer Test System The Integrating Sphere Test System make me...
The main parameters of LED lamps and lanterns include: A: Electric parameters: voltage, current, lamp power, power factor, harmonic, etc B: Colorimetric parameters: correlated color temperature, color rendering index, chromaticity tolerance, color coordinates, SDCM, etc C: Photometric parameters: luminous flux, output luminous efficiency, beam angle, UGR table, intensity distribution, candela tab...
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 c...
LED package is mainly to provide a platform for LED chips, so that LED chips have better performance of light, electricity and heat. Good packaging can make LEDs have better luminous efficiency and good heat dissipation environment, and good heat dissipation environment can enhance LEDs. The service life. LED packaging technology is mainly built on five main considerations, namely optical extracti...
High frequency fluorescent lamp came out in 1990. Fine tube, small current and high power is the distinct features. Because of the above design structure, high frequency current working, electronic ballast with low power consumption, the work system of this high frequency fluorescent lamp is superior to the traditional lamp on the aspect of lighting effect and photometric. How to measure the chara...
LED has the features of long time. According to different power drivers and use conditions, the life of LED can be up to 50,000 hours or more. LED will not extinguish directly like other light source but decay gradually. Therefore, luminous decay will lead to output low light after long time use, which will make products not meet requirements. And how to use TM-21 to estimate LED luminaries life? ...
According to the requirements of the LM-79 optical testing standards applicable to the widest range in the world, although there are many photometric measurements for light sources and lamps are available, but these standards are dedicated to the measurements for light sources and lamps. Because the form of current SSL products are lamps or luminaires, and LED in the luminaires is not easy to be ...
