The working process and principle of this embodiment are as follows:

1. Lighting of inverted polygonal table lamps: when the indoor light is dark, turn on the auxiliary lighting to adjust the indoor illuminance, when the indoor illuminance is insufficient, turn on the main lighting, and the lights arranged on the surface of several isosceles trapezoids perpendicular to the inverted polygonal table The group irradiation space is large, so that the indoor illumination is average;

2. Plum-shaped lamps and lanterns lighting: when most of the family members need to watch TV, talk or have a quiet rest, the indoor illumination needs to be reduced, while a few people need to read or read newspapers and need to increase the indoor illumination. The eccentric sheave starts to rotate forward, as shown in Figure 3, the eccentric sheave supports the ejector rod to move in a plane, the ejector rod pushes the slider to slide down along the hollow slider, and the slider pushes several connecting rods to make a plane synchronously Movement, several pendulum rods synchronously swing forward relative to the fixed support, so that several roller groups roll out synchronously along the corresponding isosceles trapezoid plane petal slides, and simultaneously push several isosceles trapezoid plane petals to expand outwards synchronously, When the connecting rod pushes the slider to slide down the hollow sliding rod to the position shown in Figure 7, the output shaft of the deceleration micro-motor stops rotating in the forward direction, and several isosceles trapezoid plane petals spread into the same plane, becoming a plum-shaped lamp for lighting. The illuminance is increased in the nearby space under the lamp, and the illuminance in other indoor spaces is reduced, which meets the individual needs of family members.

3. Restoring the inverted polygonal table lamp: the output shaft of the decelerating micro-motor drives the eccentric sheave to rotate in the reverse direction, the eccentric sheave supports the ejector rod to move in a plane, the ejector rod pulls the slider and starts to slide upward along the hollow slider, and the slider pulls Several connecting rods move in plane synchronously, and several pendulum rods synchronously and reversely swing relative to the fixed support, so that several roller groups roll inward synchronously along the corresponding isosceles trapezoid plane petal slides, and simultaneously pull several isosceles trapezoids. The plane petals are retracted inwards synchronously. When the ejector rod pulls the slider and slides up along the hollow slide rod to the position shown in Figure 3, the output shaft of the deceleration micromotor stops rotating in the opposite direction, and becomes an inverted polygonal table deformer.
