HENG is a serious of lamps breaking the traditional way to turn on lamps. The two balls in the wooden frames serve as switches of the lamps.They would float in the air and when they reach a balance, the light would be turned on. Two balls inside are actually the toggle of the lamp. By embedding magnet into the balls, these two balls would attract to each other. During this time, the line between then would be pulled up, and the toggle of the bottom would be open and therefore open the lamp. When these two balls lose the contraction, the ball would fall because of the gravity, and then the bronze piece inside the toggle would slip off and therefore cut the circuit, which eventually turn off the lamp. The outside frame of the lamp is made of beech, so that the touch feeling is natural and warm. The whole lamp uses a interesting and concise appearance, which is pretty and easy to produce.
