极限使用条件 Limitation use conditions:

项目Project 单位Unit 范围Range
Working temperature
Storage temperature
Max welding temperature


Note: It will affect the quality of the equipment,even broken if out of the limitation of the LED use confition. It is not
recommended to operate over the above limits
4、光电参数Optoelectronic parameter value :

⑴ LED储存:建议存储温度10摄氏度-55摄氏度,湿度:30%-65%,包装袋密封保存。为了保证产品质量,
LED storage: suggest to sealed stock in under the temperature of 10℃-55℃,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
⑵ 拿取方法:接触LED检查时需戴手套或者手指套,工作台面也要接地,包装袋开口后要及时封口,防止引
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.
⑶ 安装:这一过程主要是静电的防护:
Installation: This process is mainly to protect the static electricity:
① 生产前检查机台设备接地线是否正常;
Check if the grounding wire of the machine equipment is normal before production;
② 检查人员静电环是否正常,检查静电的金属与人的皮肤接触紧密;
Check if the static ring is normal, check static metal and human skin contact closely;
③ 在安装时最好要求作业人员戴好防静电手套或者防静电手指套;
Check if the workerswear anti-static gloves;
④ 作业台面铺好静电胶布,胶布之间应相互连接接地;
Check if the working table is paved with electrostatic rubber cloth, and the rubber cloth is connected
to each other.
⑤ 开封后最好在二十四小时内用完,否则可能会引起灯脚氧化生绣。
After opening the seal, it is better to use it out in 24hors, otherwise it may cause the oxidation of the
⑷ 建议使用低温锡膏进行迴流焊,温度曲线如下图所示:
It is recommended to use low temperature solder paste for reflow, and the temperature curve is shown in the
following diagram.

① 预热区
Preheating area
The temperature speed is 1.0-3.0℃/S. If the temperature rises too fast, it is easy to cause
paste mobility and component deterioration, then cause the tin explosive and phenomenon.
② 浸润区
Infiltrating area
The temperature is 110-130℃, 90-100s is the most suitable. If the temperature is too low,
then the solder will not melt if it is rewelded. It is recommended that the temperature rise
speed is <2℃/ s.
③ 回焊区
Reflow Area
The peak temperature should be set at 170-180℃. The melting time suggests to adjust to 50-
80 seconds when above 138℃
④ 冷却区
Cooling Area
Temperature cooling spead is better <4℃/ s.
⑸ LED随著电流的增加和温度的升高,他的使用寿命会呈某种曲线下降,导致LED衰减加快。
With the increase of current and temperature, the life of LED will decrease, which leads to the acceleration of
the attenuation of LED.
⑹ 建议在设计PCB时要有接地电路。特别注意LED的使用环境:温度在零下30摄氏度-55摄氏度之间,湿度
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 -30℃ to 55℃, and the humidity is between 65%. Otherwise, the
LED will be broken by electrostatic and high current breakdown.

Major security tips
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 gla
