8. Precautions

(1) Operating and storage environment

- This product shall be used or stored under the environment where no condensation or

corrosive factors such as chlorine gas, sulfur gas, acid, alkali, salt and others are present.

- In cases where this product is cleaned, bonded, and molded, these effects on product quality

need to be checked using an intended equipment.

- This product shall be stored in the conditions that ambient temperature of 5～40degC and

relative humidity of 20～70% and used within three months after being delivered.

- In cases where more than three months go by, the connectivity needs to be checked before usage.

(2) Handling

- For safety, LED light source should not be looked at directly.

- No manual or reflow soldering are availavle.

- No ultrasonic cleaning is available.

- Any detergents or chemicals should not be used since they could trigger the discoloration or

degradation of this product and electrical shock.

- Please do not expose this product to excessive shock or vibration such as drop and others.

- Please avoid the application of any stress to the sealing resin area.

- Please avoid any contact by a sharp metal nail or other materials with the sealing resin area.

- This product shall not be bent or twisted forcedly.

Such handling could apply stress to soldering area and consequently induce no-lighting or

shorten the product life significantly.

- When handling this product, some static measurements such as the wearing of a wristband or

antistatic gloves are required to prevent any static electricity effect.

Any damages due to static should be checked by lighting inspection.

CE's lighting inspection criterion

(3) Rating

- A constant current circuit is recommended as a drive circuit.

- When two or more LED modules are connected in parallel in the constant voltage circuit,

the current-limiting resistance needs to be placed on each module so that they operate within

the rating.

- Please design a circuit that prevents any reverse voltage (excess current) from being applied to

this product instantaneously when the circuit is ON or OFF.

- This product shall be measured by a K thermocouple of φ0.1mm with small thermal capacity

under the conditions where this product is unaffected by radiant heat from other components

or wind caused by convection.Exessive heat may deteriorate the LED's characteristics and

reliability.

(4) Addition of fail safe fuction

- In cases where an LED or circuit shorts out for some reasons, this may result in electrical shock,

fumes and ignition.

- To help eliminate these possibilities, please ensure that an appropriate fail-safe function such as

a fuse is provided for your product.
