Mini Lava Lamp Shake and Shine Glitter Light tells what is the luminous principle of Plasma Lamp?

2021-04-21 11:11

Common Plasma Lamps are spherical or cylindrical. Although there are many kinds, it is usually a clear glass ball filled with a mixture of various gases. Commonly used are helium and neon, and sometimes low-pressure xenon and krypton are used, usually high-frequency and high-voltage alternating current (35kHz, 2-5kV) generated by a high-voltage transformer. Another smaller sphere is located in the center of it as an electrode. The filamentous plasma extends from the inner electrode to the outer glass insulating shell, presenting multiple steady beams of colored light. The light initially travels along the electric field lines between the dipoles, but then moves upward under the influence of convection.


Bringing the hand close to the Plasma Lamp changed the high-frequency electric field, causing a beam of light to migrate from the inner sphere to the contact point. Conductors close to the glass ball will generate current inside, because glass cannot block the electromagnetic field generated by the current conducted through the plasma (although the insulator does block the current itself). The glass acts as a dielectric between the ionized gas and the hand, just like a capacitor. So do you know what its luminous principle is? Let’s follow the editor of Mini Lava Lamp Shake and Shine Glitter Light to have a simple understanding!
Using 2.45GHz microwave energy (same as household microwave ovens) to excite the luminescent substance in the quartz bulb, causing it to generate molecular radiation and emit continuous visible light. After years of research by researchers, the new technology of coaxial cavity excitation mechanism is boldly and innovatively adopted. , Further improve the light efficiency and enhance the reliability. The cost is reduced and the product is developed towards miniaturization and low power. The microwave Plasma Lamp is an energy-saving and environmentally friendly lighting source with independent intellectual property rights.
To sum up, the editor of Mini Lava Lamp Shake and Shine Glitter Light tells: I hope you can learn more about the light-emitting principle of Plasma Lamp.
