LED Sphere Spectroradiometer System

LPCE-2(LMS-8000) is an Integrating Sphere Spectroradiometer LED Measurement System designed to evaluate the performance of single LEDs and LED lamps. The quality of LEDs should be assessed by examining their photometric, colorimetric, and electrical parameters. In accordance with standards such as CIE 177, CIE84, CIE-13.3, IES LM-79, Optical-Engineering-49-3-033602, IESNA LM-63-2, ANSI-C78.377, and IES LM 79-08, it is recommended to use an array spectroradiometer with an integrating sphere and photometer head for testing SSL products. LISUN has developed the LPCE-2 test system specifically for LED products. The LMS-8000AS is an updated version of the LMS-8000A, allowing connection to two integrating spheres simultaneously. This means the LMS-8000AS can switch between the two spheres conveniently without the need to disconnect the detector cable and optical fiber between the large and small spheres. Standards include CIE 177 “Color Rendering of White LED Light Sources”, CIE84 “Measurement of Luminous Flux”, CIE-13.3 “Method of Measuring and Specifying Colour Rendering Properties of Light Sources”, LM-79-19 “Optical and Electrical Measurements of Solid State Lighting Products”, IESNA LM-63-2 “IESNA Standard File Format for Electronic Transfer of Photometric Data”, IES LM-80-08 “Measuring Lumen Maintenance of LED Light Sources”, ANSI-C78.377 “Specifications for Chromaticity of Solid State Lighting Products for Electric Lamps”, and (EU) 2019/2015 “COMMISSION DELEGATED REGULATION”. System Configuration includes CCD Spectroradiometer (LMS-8000A or LMS-8000AS), Optical Fiber (CFO-1.5M), Digital Power Meter (LS2008R), AC Power Source (LSP-500VA), Integrating Sphere (IS-1.5MA55C and IS-0.3M), and Standard Light Source (SLS-50W and SLS-10W). Measures include: Colorimetric: Total Radiant Intensity, Dominant Wavelength, Peak Wavelength, Color Coordinates, Half-Bandwidth, Spectral Purity, Correlated Color Temperature (CCT), Color Rendering Index (CRI). Photometric: Total Luminous Flux, Luminous Efficiency, Radiant. Electrical: Forward Voltage…
