1. 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 500W mercury lamp in general lighting sources. The element arrangement of LED package is capable of utilizing light more effectively and higher performance. The new version of CITILED COB Series succeed to reduce the thermal resistance significantly. New version creates more options to match luminaire's products design (ex. High performance , Cost effective , Higher lumen density , Increased allowable max. If). The outline and LES size is same since version 1. 3-step MacAdam ellipse color definition at Tj=85℃ is available.

* Color region stay within MacAdam 3-step ellipse from the chromaticity center. * The chromaticity center refers to ANSI C78.377:2011. Please refer to ANSI C78. 377 for the chromaticity center. * θ is the angle between the major axis of the ellipse and the x-axis, and a and b are the major and minor semi-axes of an ellipse. (Ref. IEC 60081:1997 AnnexD)
