Introduction 1-1. Product Description CITIZEN ELECTRONICS is the first COB manufacture. Our advanced knowledge and packaging technology for many years has excellent reliability and high quality of our products. CITILED COB Series covers a wide range of luminous flux from a 10W incandescent bulb to a 300W mercury lamp in general lighting sources. The element arrangement of LED package is capable of utilizing light more effectively and higher performance. The new package "High Intensity Type" provides smaller LES and higher flux intensity. Our new small LES (Light emitting surface) package has succeeded in producing higher flux intensity through use of our advanced packaging technology. It is suitable for luminaires with a narrow beam angle such as spot lights. Enough space around LES on the PCB accepts flexibility of optics attachment. This package is 3-Step MacAdam ellipse at hot binning. Ver.2 is improved higher lumen density and lower thermal resistance as same package outline of previous version. New lineup "low VF product (9V) " is added. 1-2. Features 2 Ref.CE-P3515 01/16 2. Performance Characteristics 2-1.
