What is the qualification standard for the supplier of customized LED purification light supplier?

Information

Why can the LED purification lamp achieve the cleaning effect, and what standards must it meet to achieve the cleaning effect? ​​

In the factory inspection, what aspects must be strictly inspected, after the strict inspection, the inspection is qualified and there is no problem. Circulate to the market. So, what aspects do customized LED purification light supplier actually inspect? In fact, the key to the testing standards of customized LED purification light supplier has the following aspects:

 

1. Material selection

 

The LED purification lamp can be made into a spherical straight tube type and other shapes. Taking the straight tube type LED purification lamp as an example, its shape is the same as a general fluorescent tube. The fluorescent tube transparent PC polymer shell encloses the power module and light-emitting diode inside. The transparent polymer shell has the function of preventing fire and electric shock in commodities. According to the standard, the purifying lamp housing material must be above V-1 level, so the transparent polymer housing must use materials above V-1 level. The product shell must reach the V-1 level, and its thickness must be greater than the thickness specified by the V-1 level of the raw material. The fire rating and thickness regulations can be found on the UL yellow card of the raw material.

 

2, drop test

 

According to the product standard, the LED purification lamp should simulate the drop that will occur during the specific use process for drop test. The product should be dropped from a height of more than 0.91 meters onto the hardwood board. The shell of the LED purification lamp cannot be cracked, let alone Expose internal risky charged components. On the other hand, when material manufacturers select materials for product shells, they must do this test beforehand and make sure that there are no problems before mass production. This can prevent damage caused by mass production failure.

 

3, electric strength

 

The transparent shell of the LED purification lamp encloses the power module inside, and the material of the transparent shell must meet the requirements of electric strength. Under normal circumstances, the thickness of the product shell reaches up to 0.8mm, which can meet the requirements of the electric strength test.

 

 

4, insulation regulations

 

Because the internal space of the LED purification lamp is limited, in the structural design, special attention should be paid to the insulation regulations between the risky live parts and the touchable metal parts. Insulation can be space distance and creepage distance, naturally it can also be an insulating sheet. According to the standard, the space distance between risky live parts and touchable metal parts must reach 3.2mm, and the creepage distance must reach 6.4mm. If the distance is insufficient, an insulating sheet can be added as additional insulation. The thickness of the insulating sheet should exceed 0.71mm. If the thickness is less than 0.71mm, the LED purification lamp can withstand the high voltage test of 5000V.

 

5. Temperature test

 

The temperature test is a must-do item for the LED purification lamp test. The standard has certain temperature limits for different components. In the product design stage, lighting manufacturers should pay great attention to the heat dissipation of the product, and pay special attention to some parts. If the components are operated under high temperature standards for a long time, their physical properties will be changed, which will cause the risk of fire or electric shock. The power module inside the lamp is in a closed and narrow space, and the heat dissipation is limited. Therefore, when customized LED purification light supplier carry out component selection, they must pay attention to selecting the specifications that suit the components, and ensure that the components will work normally under a certain temperature standard, so as to prevent the components from overheating caused by long-term work near the full-load standard. A situation that creates a risk of fire or electric shock.
