1. Introduction
1-1. Product Description
CITIZEN ELECTRONICS was the first COB manufacturer.
Our long-term advanced knowledge and packaging technique have enable us
to provide products with excellent reliability and high quality.
The High Intensity Ver.3 has been developed as a high performance product with high luminous flux
through the full use of the CITIZEN ELECTRONICS' packaging techniques.
We have added the new LES size of φ3.3mm and φ4.2mm to our product lineup, which makes it possible to realize
narrower light distribution than before and as a result contribute to the downsizing of optical parts.
The High Intensity Ver.3 offers an opportunity to develop compact and high performance truck light,
downlight, lamp and other lighting products due to its high performance.
