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
froma 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 MacAdamellipse color definition at
Tj=85C is available.
