NOTE: The typical divergence will be changed by different color, chip size and chip position
tolerance. The typical total divergence is the full angle measured where the luminous intensity
is half of the peak value.

NOTE 1: We advise customer to ensure the suitability and sufficiency of the bond in the end
product. For example, mechanical stress, vibration and holes on the surface of the circuit boar
weaken the strength of the tape.
NOTE 2: Assembly to the surface must be made straight, so the tape bonds constant and
balanced with fastening surface. Slanted assembly might cause unbalanced bond to the
surface. All surfaces where tape is applied must be clean, dry and free from grease and dirt.
If cleaning of PCB surfaces is needed, please follow strictly the cleaning instructions of your
LED manufacturer - this is important as cleaning shall under no circumstances damage LEDs or
other electronics components on the PCB.
Further note that optical components shall not be cleaned with any chemicals - only micro fiber
cloth may be used to remove fingerprints or other traces from handling.
