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.

(4) Handle the component along the side surface by using forceps or appropriate tools; Do not directlytouch or

Handle the silicone lens surface, it may damage the internal circuitry.
