영화의전당 미디어파사드에 적용한 레귤레이터 성능향상에 관한 연구

Abstract

Scenic lighting system of Busan Cimema Center using diffusion effect of light is a system to express natural flexible could roof by diffusing LED light to polycarbonate panel(semi-transparent panel). This study aims at figuring out causes of problems to operate LED media facade in Busan Cimema Center and their solutions. As a result of malfunction module analysis during operation of LED media facade of Busan Cimema Center, in the soldering part of the module, there was a cold solder and it was confirmed as main cause of non-lighting As the results of module test of heat-resistance performance of regulator in higher temperature and test of temperature raising, cause of module malfunction was incomplete contact of PINs(Nos. 5, 6, 7, and 8) of the regulator and it seems to be caused by non-smooth heat-resistance of the regulator.
