Its shell is a high-strength glass shell, the ball is filled with a thin 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. Through the power converter, the 5V low-voltage direct current is converted into a high-voltage and high-frequency voltage and applied to the electrode. After power is turned on, the arc formed by the electrode plus the high voltage to excite the inert gas generates a beam of light, so the light generated is like some radiant glow, colorful and radiant, and very beautiful in the dark.
