As one of today's most critical light sources, Light-Emitting Diodes (LEDs) are ubiquitous across industries—from automotive lighting and consumer electronics to horticulture and medical devices. Their rapid development has led to a vast array of colors, luminances, and form factors. However, the unique shape and characteristics of LED emitting surfaces make precise optical measurement a significant challenge. Accurate quantification of parameters like spectral power, chromaticity, and luminous flux is essential for quality control, performance validation, and R&D.
The unique shape of the LED light -emitting surface makes it difficult to homogenize the luminescence. The way by reducing light loss through the use of integrating spheres is suitable for most LED measurement applications. For optical radiation measurements, integrating sphere is a very important part. The inner surface of the integrating sphere has perfect scattering, and the light is uniformly reflected on its inner surface, resulting in the same degree of light exposure at any point on the wall. The combination of the integrating sphere and the spectrometer makes a stable measurement.
