4.5V Plasma Globe Lamp with Power Adapter EU PlugFeatures:.Product Description: The shape of this product is quite like a magic ball, and when the power is turned on, it will emit a wonderful "light", dancing like an electric current. At this time, touch the sphere with your hand, and the light will run to the contact point of the hand and the sphere , Make you feel as if you are in space;.Principle: Its shell is a high-strength glass shell, the ball is filled with rare inert gas, and there is a black spherical electrode in the center of the glass ball.
There is an oscillating circuit board at the bottom of the ball, which converts low-voltage direct current into high-voltage and high-frequency voltage through a power converter and is applied to the electrodes. After power-on, the arc formed by the electrodes and the high-voltage excitation inert gas produces a light beam, so the light generated is like some radiant glow, colorful and radiant, very beautiful in the dark.
When the ion ball is working, a field similar to a point charge is formed around the electrode in the center of the ball. When the ball is touched with the hand (a person is connected to the earth), the electric field and potential distribution around the ball are no longer uniform and symmetrical, so the glow around the finger becomes brighter, and the arc generated moves along with the touch of the hand.
