Led Street Light Housing Manufacturer introduces the knowledge of static electricity:

1. The generation of static electricity:
   ① Friction: In daily life, when any two objects of different materials are contacted and then separated, static electricity can be generated. The most common method of generating static electricity is friction. The better the insulation of the material, the easier it is to generate electricity by friction. In addition, any two objects with different materials contact and then separate can also generate static electricity.

② Induction: For conductive materials, because electrons can flow freely on its surface, if it is placed in an electric field because the same-sex repels and the opposite sex attracts each other, positive and negative ions will be transferred, and charges will be generated on the surface.

③ Conduction: For conductive materials, because electrons can flow freely on its surface, such as contact with a charged object, charge transfer will occur.

1. The harm of static electricity to LED:

① Due to the heat generated by the instant electric field or current, the LED is locally injured. The leakage current increases rapidly and can still work, but the brightness is reduced (white light will change color) and the life span is impaired.

② The insulating layer of the LED is destroyed by the electric field or current, making the device inoperable (completely destroyed), and it appears as a dead light.

1. Electrostatic protection and elimination measures:

For the entire process (production, testing, packaging, etc.), all employees who are in direct contact with the LED must take measures to prevent and eliminate static electricity, mainly:

① Lay an anti-static floor in the workshop and ground it well.

②The workbench is an anti-static workbench, and the production machine is well-grounded.

③The operator wears anti-static clothes, anti-static wristbands, gloves, or foot rings.

④ Use ion fan and soldering iron to make grounding measures.

⑤The packaging is made of anti-static materials.
