Abstract

The invention discloses a matrix-type LED vehicle lamp on-line detection system and belongs to the intelligent detection technology field. The system comprises an image acquisition and processing system, a data acquisition system and a light modulation tooling. Matrix-type LED vehicle lamp performance can be tested, through an industrial camera, the light shape of a vehicle lamp is detected and correlation image processing is performed. A current card and an A / D card are adopted to test an LED driving current and a voltage respectively. In the invention, the coverage and the accuracy of matrix-type LED vehicle lamp detection are increased, equipment is reliable, operation is easy and product manufacturing quality reliability is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of intelligent detection, in particular to an on-line detection system for matrix LED vehicle lights. Background technique [0002] With the rapid development of the automobile industry at home and abroad, automobile lights are developing from a single lighting function to a multi-functional and intelligent direction. Halogen lamps are gradually replaced by LED lamps as traditional car lighting means, and matrix LED lamps can realize more complex functions of headlights by intelligently controlling the changes of LEDs. As an important tool for safe driving and lighting, the performance testing of matrix LED lights is extremely important. At present, the detection method for matrix LED lights is usually to transmit the light onto a screen 10 meters away, and manually check whether the light shape meets the requirements. This method is feasible for laboratory testing, but it is obviously not suitable for pro...
