Cold cathode fluorescent (CCFL) lamps and UV lamps are lighting sources derived from gas discharge, and the conjunction of these two technologies can provide light with multiple colors. The BF6165-20B is a kind of lighting source equipment which utilizes both these technologies.

The structure of the BF6165-20B lighting source equipment is mainly composed of an arc tube, a gas pre-filled ballast and a socket. The arc tube is a hollow glass tube filled with noble gas like xenon, and is sealed at both ends with molybdenum electrodes. The inside wall of the glass tube is coated with a fluorescent material, which generates visible light when the arc tube is discharged. The gas pre-filled ballast, which is an important part of the BF6165-20B, is a cruciform circuit board with a negative resistance characteristic. It is mainly composed of a transformer, a series connected rectifying diode, and an inductance coil. TheConnection of the socket is equipped with an AC220V power supply, which is the main power supply in the BF6165-20B.

The working principle of the BF6165-20B lighting source equipment is as follows: When AC220V power is connected to the socket of the equipment, the transformer in the gas pre-filled ballast of the equipment will convert the AC220V voltage into low-voltage alternating current first. Then the rectifying diode will conduct the alternating current, and then the inductance coil will emit the rectified electrical energy into the arc tube. Thus, the noble gas in the arc tube ionizes, and then generates a negative-resistance arc. The fluorescent material inside the glass tube will absorb the energy generated by the arc and emit visible light. Moreover, when the arc is discharged, UV light will also be generated, which is used to sterilize and disinfect areas.

In conclusion, the BF6165-20B is a type of lighting source equipment with a dual function of both cold cathode fluorescent and UV lights. It has a gas pre-filled ballast with a negative resistance characteristic, and a socket with an AC220V power supply. Its working principle is to convert 220V AC voltage into low-voltage AC current in the pre-filled ballast, and then use this current to discharge the Arc tube. When the arc tube is discharged, visible light and UV light will be generated in the equipment, which can be used for various purposes such as illumination, sterilization and disinfection.
