  • IES LM-79-08 “Electrical and Photometric Measurement of Solid-State Lighting Products” as the exclusive international standard for measuring the total luminous flux, electrical power, luminous intensity distribution and correlated color temperature (CCT), color rendering index (CRI) and other colorimetric parameters of solid-state lighting products (SSL), it highlights the total luminous flux of SSL products should be measured with the integral sphere system or goniophotometer. So the integrating sphere, as one of…

  • IEC 60825-1: 2007 is a standard issued by the European Union, applicable to safety of laser products emitting laser radiation in the wavelength range 180 nm to 1 mm. Its scope of application would be only applied to LASER products after September 2010, and LED lighting products are no longer covered by the latest version of IEC / EN 60825-1, but need to be assessed in accordance with IEC /…

  • ISO17025 is the international standard for laboratory accreditation services; the latest version is released in May, 2005. The full name of ISO/IEC17025:2005-5-15 is Accreditation Criteria for the Competence of Testing and Calibration Laboratories. ISO17025 standard is the laboratory management standard formulated by the international Standardization Organization ISO/CASCO (Conformity Assessment Committee). Internationally the organization that manages laboratory accreditation is International Laboratory Accreditation Cooperation (ILAC), attended by 44 laboratory accreditation institute including…

  • Light environment is one of the indispensable and important physical environmental factors for plant growth and development. LED plant lighting lamp is a kind of artificial light source to meet plant photosynthesis light conditions. In the absence of sunlight, lamp can act as daylight. Plant growth lights play the function of environmental protection and energy conservation. LED plant lights provide photosynthesis light conditions, promote plant growth, short the time of…

  • LED adopts metal material, however, OLED uses organic material. Their emitting principles are the same, the difference is that OLED does not need backlight, because it is composed of light-emitting diode array and it can emitting itself. It is brighter and thinner than LED LCD display, and it will become an alternate of LED LCD display in the future. LED LCD display needs backlight. Its brightness is common, and displays…

  • During electromagnetic radiation test, three loop antennas are often used. Lisun three loop antenna VVLA-30M is a standard measurement antenna according to CISPR15-2005. It can coordinate Lisun EMI-9KB or EMI-9KA EMI Receiver System for EUT magnetic field radiation test measurement between X, Y and Z planes. VVLS-30M is a big antenna with 2m diameter, which is used for testing frequency below 30MHZ radiation electromagnetic field, frequency range is 9 KHz~30MHz….
