Led test system - lpce-2(lms-9000a) spectroradiometer & integrating sphere test system instruction: Lpce-1 integrating sphere spectrophotometer test system is suitable for photometric and colorimetric measurement of luminaries such as energy-saving lamps, fluorescent lamps, hid lamps (high voltage sodium lamps and high voltage mercury lamps), ccfl and led. The measured data meets the requirements of cie and ies lm-79 for the measurement of photometry and colorimetry. System configuration: Quick-scan spectrophotometer colorimeter(lms-5000), optical fiber (cfo-1.2m), digital power meter (ui2008r, option is ui2010), dc power supply (wp3005, option is wp502), ac power source(lsp-500va, option is lsp-1kva or lsp-3kva), integrating sphere (is-1.5m, option is 1.0m or 2.0m size), standard lamp source (sls-50w), 19 inch case Spectrophotometer integrating sphere system measures photometry, colorimetry and electricity: • color parameters: chromaticity coordinate, cct (correlated color temperature), cri (color rending index), color difference, peak wavelength; • photometry parameters: luminous flux, luminous power, luminous flux efficiency; • electrical parameters: voltage, current, power, power factor Woden case
