Precautions for 255 254nm UVC LED chip use

(1) Storage:

  ● To avoid the influence of moisture, we recommend that the product be stored at 5-30°C and the relative humidity is less than 60% before opening the package;

  ● The unpacked LED light source should be used and installed within 24 hours. If the product is not used up, please dehumidify and vacuum it before storing. When opening for more than one week or the humidity card changes, please be sure to dehumidify. Dehumidification conditions: 60°C±5°C, 12H;

● The product is sealed and stored for one year.

(2) Precautions for assembly:

● Soldering conditions: This product must use reflow soldering. The maximum temperature of the reflow curve should not exceed 260°C. During operation or storage, no external force above 1000g or sharp objects should act on the surface of the lamp bead (such as pressure, friction, etc.) And tools such as pliers and tweezers) to avoid component damage;

● If the operating conditions are exceeded, we will not be able to guarantee the stability of the product. If you need to use the operating conditions beyond, be sure to conduct a risk assessment.

(3) Anti-static measures:

● Please take sufficient measures to prevent static electricity generation, such as wearing static rings or anti-static finger cots; products (factories, equipment, machines, carrier machines, and transportation units) in each manufacturing process should be connected to the ground to avoid electrical charging of products.

(4) Temperature control:

● To ensure that the contact thermal resistance is reduced during assembly, please note that during the assembly process, the heat sink is evenly coated with good-quality thermal paste and the distribution area is reasonable, and there must be no too little or uneven height.

●The heat dissipation medium must ensure that the dielectric withstand voltage test is at least 500V.

(5) Drive control:

● This product needs to be driven by a constant current source, and the output current meets the power usage range in the specification. If you need to use a constant voltage source or other usage conditions, please conduct a risk assessment of the use effect.

(6) Other:

● This product cannot be used under the following conditions. If the product is used under the following conditions, please evaluate its use risks and effects:

---Direct or indirect wet or damp, such as rain, etc.;

---Damage or erosion by sea water;

---Be exposed to corrosive gases (such as Cl2, H2S, NH3, SOx, NOx, etc.);

---Be exposed to dust, liquid or oil;

● All high-power light-emitting LED products are installed on aluminum metal as the core printed circuit board, which can be directly lit, but we do not recommend lighting high-power LEDs for more than 5 seconds without a proper heat dissipation device;

●This product is an LED emitting short wavelength. During use, the LED emits high-intensity ultraviolet light, which can damage the skin and eyes.

Ultraviolet light can damage the skin and even cause cancer. Avoid exposure to ultraviolet light during operation.

Take care to avoid looking directly at the UV light without UV protective glasses. It is not allowed to look directly into the lens of the LED when it is on.

● Reflow soldering should not exceed twice. The maximum temperature of reflow soldering is recommended to be below 260℃. When the temperature exceeds 260℃, LED products may fail;
