Hot Selling 8*8*13cm USB Magic Black Base Glass Plasma Ball Sphere Lightning Party Lamp Light With USB Cable.

Although many variations exist, a plasma lamp is usually a clear glass sphere filled with a mixture of various gases (most commonly neon, sometimes with other noble gases such as argon, xenon and krypton) at nearly atmospheric pressure. A crackle tube is a related device filled with phosphor-coated beads. Plasma lamps are driven by high-frequency (approximately 35 kHz) alternating current at 2–5 kV.[1] The drive circuit is essentially a specialized power inverter, in which current from a lower-voltage DC supply powers a high-frequency electronic oscillator circuit whose output is stepped up by a high-frequency, high-voltage transformer. The radio-frequency energy from the transformer is transmitted into the gas within the globe through an electrode at its center. Additionally, some designs utilize the globe as a resonant cavity, which provides positive feedback to the drive transistor through the transformer. A much smaller hollow glass orb can also serve as an electrode when it is filled with metal wool or a conducting fluid that is in communication with the transformer output. In this case, the radio-frequency energy is admitted into the larger space by capacitive coupling right through the glass. Plasma filaments extend from the inner electrode to the outer glass insulator, giving the appearance of moving tendrils of colored light within the volume of the globe.
