4. Handling Precautions

4.1 Handling Precautions

(1) LED operating environment and sulfur element composition cannot be over 100PPM in the

LEDmating usage material. This is provided for informational purposes only and is not a warranty

or endorsement.LED

(2) In order to prevent ex-ternal material from getting into the inside of LED, which may cause the

malfunction of LED, the single content of Bromine element is required to be less than

900PPM,the single content of Chlorine elementis required to be less than 900PPM,the total

content of Bromine element and Chlorine element in the external materials of the application

products is required to be less than 1500PPM. This is provided for informational purposes only

and is not a warranty or endorsement.

(3) VOCs (Volatile organic compounds) emitted from materials used in the construction of fixtures

can penetrate silicone encapsulants of LEDs and discolor when exposed to heat and photonic

energy. The result can be a significant loss of light output from the fixture. Knowledge of the

properties of the materials selected to be used in the construction of fixtures can help prevent

these issues. Refond advises against theuse of any chemicals or materials that have been found

or are suspected to have an adverse affect on device performance or reliability. To

verifycompatibility, Refond recommends that all chemicals and materials be tested in the specific

application and environment for which they are intended tobe used. Attaching LEDs, do not use

adhesives that outgas organic vapor.
