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

1. Inverted polygonal table lamp lighting: 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 lamp lighting, vertical to several isosceles trapezoidal surfaces of the inverted polygonal table. The illumination space of the lamp group 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 when the indoor illumination needs to be increased, the output shaft of the deceleration micro-motor is driven. The screw starts to rotate forward, as shown in Figure 3, the screw pushes the slider to slide down along the hollow sliding rod, the slider pushes several connecting rods to make plane motion synchronously, and several pendulum rods synchronously swing forward relative to the fixed support , make several roller groups roll out synchronously along the corresponding isosceles trapezoid plane petal slides, and simultaneously push several isosceles trapezoid plane petals to expand out synchronously. When the position is shown, the output shaft of the deceleration micromotor stops rotating in the forward direction, and several isosceles trapezoid plane petals are spread into the same plane. The nearby space under the lamp increases the illuminance, while other indoor spaces reduce the illuminance to meet the individual needs of family members.

3. Restoring the inverted polygonal table-shaped deformed lamp: the output shaft of the deceleration micro-motor drives the screw to rotate in the reverse direction, the screw pulls the slider to start sliding upward along the hollow sliding rod, the slider pulls several connecting rods to synchronously move in a plane, and several pendulums The rod swings synchronously and reversely relative to the fixed support, so that several roller groups roll inwards synchronously along the corresponding isosceles trapezoid plane petal slides, and simultaneously pull several isosceles trapezoid plane petals to retract inward synchronously. The arc-shaped polygon groove is conducive to retracting the petals. When the screw pulls the slider and slides up along the hollow sliding rod to the position shown in Figure 3, the output shaft of the deceleration micro-motor stops rotating in the reverse direction, and becomes an inverted polygonal table-shaped deformed lamp. .
