Abstract
LED test can be done in several stages of the manufacturing process of a device. Although ICTs can check the electrical parameters of LEDs, they do not always have extensions for chrominance and luminance measurements. This paper presents a test system for both colour and light intensity of LEDs, designed to communicate with a computer via USB. Test system has a graphical interface that allows operation in two modes: LED tester or colour detector. Also, the test system can be integrated into an ICT, through small changes to the program running on the computer, to be called from the program that controls the ICT.
