All characteristics are measured by GZYSLED LED storage: suggest to sealed stock in under the temperature of 10ºC-55ºC,humidity of 30%-65%.In order to keep a good quality, pls use it within 1 year after the prodcution date; and use it out within 28days after open the package. When taking or touch the LED, pls make sure to wear the gloves. Seal the package in time in orde to avoid the pin oxidation. When openning the package, need to use the weezers clamped on both sides of LED in order not to touch the face of the LED.
Installation: This process is mainly to protect the static electricity
Check if the grounding wire of the machine equipment is normal before production;
Check if the static ring is normal, check static metal and human skin contact closely;
Check if the workerswear anti-static gloves;
Check if the working table is paved with electrostatic rubber cloth, and the rubber cloth is connected to each other.
After opening the seal, it is better to use it out in 24hors, otherwise it may cause the oxidation of the foot.
It is recommended to use low temperature solder paste for reflow, and the temperature curve is shown in the following diagram.
With the increase of current and temperature, the life of LED will decrease, which leads to the acceleration of the attenuation of LED. It is suggested that a grounding circuit should be used in the design of PCB. Pay special attention to the usage environment of LED: the temperature is between - 30ºC to 55ºC, and the humidity is between 65%. Otherwise, the LED will be broken by electrostatic and high current breakdown. The photoelectric properties levels are decided by GZYSLED. There are differences between the different levels of products, please use it in a stuitable way according to the using conditions of the clients. We have been making constant efforts to improve the performance of LED products. Pls contact us for the latest specifications. This product is a deep ultraviolet LED, which will produce ultraviolet light after the correct operation of electricity. Thus it is harmful to the skin and eyes of the human body. No protective measures should be avoided directly in deep ultraviolet light.
It is recommended to wear protective clothing,gloves and glasses during operation.
