In order to obtain a better stable output, UV-LED needs a good heat dissipation environment or heat dissipation system. It is recommended that the lamp bead should not exceed 50℃ in working condition.

Typical Photoelectric Parameter Curve

Reliability Test Project and Conditions :

Criterion for unqualified reliability test :

IV : attenuation is excess of 30%

IF : change over 20%

Remark :

The test of the same sample experimental result should be completed within 2 hours

The test shall be carried out only after each test is completed and the material returns to normal environmental conditions.

Notes :

1.Storage

In order to avoid the influence of moisture, we recommend that the product be stored at 5-30 ℃ before opening the package, and the relative humidity is less than 60%.

The LED light source that has been opened should be used and installed within 24 hours. If it is not used up, it should be dehumidified and sealed after vacuuming. Dehumidified must be carried out when the humidity card is opened for more than a week. Dehumidification conditions : 60℃±5℃, 12H

The product shall be sealed and kept for one year.

2.Matters needing attention in assembly

Welding conditions : the product must be operated by reflow welding. The maximum temperature of the reflow curve shall not exceed 260℃. during operation on storage, external force or sharp objects of more than 1000g shall not act on the surface of LED lamp beads (such as external force, like pressure, friction and tools such as pliers and tweezers), so as to avoid component damage.

If these conditions are exceeded, we will not guarantee the stability of the product. If these conditions are exceeded, please be sure to conduct a risk assessment.

3.Anti-static measures

Take adequate precautions to prevent static electricity, such as with a static ring or anti-static finger sleeve. Each manufacturing plant with respect to the product (plant, equipment, machine, carrier and transport unit) shall be connected to the ground to avoid electrification of the product.

4.Temperature control

In order to reduce the contract thermal resistance during the assembly, please note that during the assembly process, the heat dissipation fins shall adopt good quality thermal conductive paste and have a reasonable distribution area, without too little or high or low inequality.

The heat dissipation medium shall pass the voltage withstand test of dielectric at least 500V.

5.Drive control

This product needs to be driven by constant current source, and the output current conforms to the power use range in the specification book. If constant voltage source or other use conditions are needed, please conduct risk assessment of the use effect.

6.Others :

This product may bot be used under any of the following conditions. If the product is used under any of the following conditions, please evaluate its use risk and effect.

-- directly or indirectly getting wet, as in the rain

-- damaged or eroded by sea water

-- exposure to corrosive gases (e.g. CI2, H2S, NH3, SOx, NOx, etc.)

-- exposure to dust, liquid, or oil

All high power light emitting LED products are mounted on aluminum metal core printed circuit boards that can be lit directly. But we do not recommend lighting high-power LED lighting for more than 5 seconds without a proper cooling equipment room.

The product emits a short wavelength LED. During use, LEDs emit high levels of ultraviolet light, which can damage the skin and eyes.

UV light can damage the skin and even has the risk of cancer. Avoid exposure to UV light during operation.

Take care to avoid direct exposure to ultraviolet light without UV protective glasses. LEDs are not allowed to look directly at their lenses when lit.

Reflow soldering should not be done more than twice. The maximum temperature for reflow soldering is recommended below 260℃. when the temperature exceeds 260℃, it is very likely to cause LED product failure.

In order to obtain a better stable output, UV LED needs a goods heat dissipation environment or heat dissipation system. It is recommended that the lamp bead should not exceed 50℃ in working condition.

Lead-free reflow welding curves are as follows (the maximum temperature is set at 260℃)
