Certificate
Precaution for use
■Product specification
一、Storage/use：
1.In order to avoid moisture absorption, it is suggested to store the products in a drying cabinet with desiccant. The storage temperature is 5℃~30℃, and the humidity is ≤60%.
2. After storage for six months, it is recommended to re-use the spectral separation to prevent changes in photoelectric parameters
3.It is recommended to dry products that have been sealed and stored for more than six months before use. The drying condition is 65℃±5℃ for 10 hours
4.The product shall be used within 24h after opening, otherwise it shall be baked at 65℃ for 4-6h before reflow welding
5. Do not press the gel surface with any sharp object (such as tweezers).Do not leave fingerprints on the surface of the colloid.The positive normal pressure of the colloid should be less than 2 newtons and the number of press should be less than 3 times.The lateral pressure of the lens body is less than 1.5 newtons and the number of press is less than 3 times.Pick up materials correctly.
二、Products should not be in contact with water, oil or organic solutions。
三、The operating current value of the product should consider LED junction temperature
四、Repackage unused products in moisture-proof bags and store in a dry place
五、External dimensions are subject to change without prior notice
六、Anti-static requirements: when using products, must wear anti-static ring or anti-static gloves, all equipment, devices, machines must be effectively grounded. This product belongs to electrostatic sensitive device, pay attention to anti-static protection!
七、When LED working, push the temperature of PCB board should not exceed 60℃.
八、Anti - vulcanization, chlorination, bromination and other treatments：
In the closed, high temperature environment, the lamp may contain sulfur/chlorine/bromine and other substances, these sulfur, chlorine and bromine elements will volatilize into gas and corrosion LED light source. Because the LED seal silica gel has porous structure, and the light source silver plating reaction occurred. After curing reaction of LED light source, the functional area of the product will darken, the luminous flux will gradually decline until it becomes slightly bright, and the color temperature will drift obviously, and the LED light source will eventually fail. It is recommended to conduct sulfur emission test of lamps first to ensure that LED light source works in sulfur-free/chlorine/bromine and other material environment.
九、When the customer applies LED, it shall refer to the parameters of this specification and the requirements of operating environment. If the LED is used beyond the parameters or standard conditions without verification, our company will not make any quality guarantee。
十、Other points for attention,please refer to our LED user manual.
