This is a new generation light source that actualized a thin and compact brand new form by applying a new socket method that has a structure that radiates heat robustly to a lighting fixture. This innovative method was developed with a German socket manufacturer BJB GmbH & Co. KG. We actualized this form including power circuits with the structure by connecting a light source and a lighting fixture thermally. By this method, we actualized both compact size and 1600 lm high output and it improves flexibility of designing lighting fixtures that require a high output light source and also makes it possible to extend new lighting fixture design.
