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 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 version of CITILED COB series increase the performance significantly from previous version. New version
creates more options to match luminaire's products design (ex. High performance , Cost effective , Small Light Emitting
Surface(LES), Increased allowable max. If). Emitted light density of the LED package is improved higher for suitable use of
light-condensing products. The outline and LES size is the same as for previous version. Thus existing parts of 3rd
parties are compatible in mechanical characteristics. All of specs are at hot binning (Tj=85
℃
).
