1,Product naming rules:
Explain:
X stands wavelength
Y stands for size
Z stands for stent type
T stands for power value
2,Size:
Note:
In order to have a stable output, UV LED need a very good heat
release enviroment
or a good heat release system. We suggest the temperature of holder
could not be
over 50℃ when LED is working.
3,Limitation use conditions:
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,Optoelectronic parameter value :
Note:
①:Output power measurement tolerance is 10%
②:Voltage measurement tolerance is 0.1V
③:Wavelength measurement tolerance is 1nm
④:Average Pulse: (Frequency1KHZ, Bias:5%);
The biggest working electric curren:60mA; Average Pulse
5,Output power levels
6,Photoelectric characteristics (TA=25℃)
7,Instructions:
⑴ 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 package.
⑵ 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 Installation: This process is mainly to protect the static
electricity:
① Check if the grounding wire of the machine equipment is normal
before production;
② Check if the static ring is normal, check static metal and human
skin contact closely;
③ Check if the workerswear anti-static gloves;
④ Check if the working table is paved with electrostatic rubber
cloth, and the rubber cloth is connected to each other.
⑤ After opening the seal, it is better to use it out in 24hors,
otherwise it may cause the oxidation of the foot.
⑷ It is recommended to use low temperature solder paste for reflow,
and the temperature curve is shown in the following diagram.
① 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 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 The peak temperature should be set at 170-180℃.
The melting time suggests to adjust to 50-80 seconds when above
138℃
④ Temperature cooling spead is better <4℃/ s.
⑸ With the increase of current and temperature, the life of LED
will decrease,
which leads to the acceleration of the attenuation of LED.
⑹ 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 the protectective clothing, glove and
glasses druring operation.
