Yi
熠
5W Series
“Yi [Yi] is the English translation for the Chinese word meaning Dazzling or Sparkling. This
multi-chip package has the brightness to illuminate the space around it, a beacon in the dark.”
Introduction
The Yi series is a high power, 4-chip device with very low
thermal resistance as a result of the ceramic substrate. The
series is a surface-mount high-power device featuring high
brightness combined with a compact size that is suitable for
all kinds of lighting applications such as general illumination,
spot, signal, industrial and commercial lighting.
