Abstract
In the machine vision system of steel production line, the obtained image qualities are greatly affected by brightness and wavelength band of illumination. The surface temperature of a continuous casting material is very high, 600~1000 °C. But the operation temperature of COB type LED is maximum 90 °C. Therefore, any special cooling systems are needed to use in these high temperature environment. In this paper, we have developed COB type LED lighting system for high temperature machine vision equipment. Our LED lighting system consist of air filter module, heat sink module, reflector and reflecting plate, heat blocking glass, air injector and circulation module. We suggest air curtain system to heat block in front of heat-blocking glass. Through the test, we have confirmed that our air curtain system will drop the internal temperature to below 80 °C in the circumstance of high temperature 600~1000 °C.
