USB power supply, which has a high-strength glass shell, the ball is filled with thin inert gas, and there is a black spherical electrode in the center of the glass ball. The bottom of the ball has an oscillating circuit board, through the power converter, the 5V low-voltage DC power into a high-voltage high-frequency voltage added to the electrode. After energized, the electrode plus high voltage excitation of inert gas formed by the pulling arc to produce a light beam, so the light that occurs like some radiation-like glow, brilliant and colorful, radiant, very good-looking 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 touching the ball with the hand (people connected to the earth), the electric field around the ball, the potential distribution is no longer uniform and symmetrical, so the glow becomes brighter around the finger, the resulting arc moves along with the touch of the hand and wanders and twists, dancing with the movement of the finger.

No flicker, protect your eyes. No infrared, ultra violet, healthier. Low voltage operation is safer. Low power, high efficiency, more energy efficient. Long service life. Low carbon green. Smart, fashion, simple. Applicable to study, dormitories, offices, hotel rooms etc.
