     Among the ultraviolet rays, light with a wavelength between 200 nanometers and 350 nanometers is called deep ultraviolet, which is widely used in air sterilization and formaldehyde treatment in water purification plants, hospitals, and factory clean rooms. In the past, many deep ultraviolet light sources used mercury lamps, but the "Minamata Convention" signed by the ...

1 LED lamp package explanation Simply put, the LED package is the package of the LED (Light Emitting Diode) light-emitting chip. Compared with the integrated circuit package, there is a big difference, which is the process of packaging the LED packaging material into an LED lamp.2 LED lamp packaging process Generally, LED packaging must go through the processes of crystal expansion-die bonding-wir...

Charge transfer occurs due to the existence of electric charge and electric field, thus forming two energy with opposite voltage polarity called static electricity. Static electricity is not static electricity. Static electricity is the same in nature as common electricity, and is essentially an electric charge.Static electricity is everywhere around us. Even in an environment with adequate static...
