The LED (Light-Emitting Diode) test facility is a specialized setup designed for the evaluation and characterization of LEDs. LEDs are semiconductor devices that emit light when an electrical current is passed through them. This facility enables comprehensive testing of various properties, including luminous intensity, color temperature, color rendering index, forward voltage, reverse leakage current,and thermal behavior. The LED test facilities in our laboratory consist of precise measurement instruments, such as spectrometers, integrating spheres, power meters, and thermal chambers. These tools allow for accurate measurement of the LED's optical and uniformity.
