Glue
Improve glue LED light effects to enhance the refractive index is the
key to the industry to use the glue most of the refractive index of 1.4
to 1.5, while the Japanese manufacturer announced recently developed a
refractive index up to 1.9 of glue, if the glue in the reliability side
can be accepted by the industry, will enable efficient LED light to
move forward in a large stride. |
