## Abstract

The present invention relates to a dynamic lighting device, including at least two lamps and a base. Each of the at least two lamps is connected to a respective paired flexible stalk configured to rotate in a circumferential direction of the base. When the flexible stalks rotate in the circumferential direction of the base, due to dynamic bending deformation of the flexible stalks, the at least two lamps have random movement in an upright direction and the at least two lamps have circumferential random wiggles against a joint defined between the flexible stalks and the base as a pivotal point.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

A dynamic lighting device, comprising
at least two lamps and a base,
being characterized in that each of the at least two lamps is connected to a respective paired flexible stalk configured to be able to rotate with respect to the base,
so that when the flexible stalks rotate with respect to the base, due to dynamic bending deformation of the flexible stalks, the at least two lamps have random movement in an upright direction and the at least two lamps have random wiggles against a joint defined between the flexible stalks and the base as a pivotal point;
wherein the top surface of the base is provided with a solar panel, and the solar panel is electrically connected to a power storage assembly through a mainboard.

### Claim at position 3

11-19. (canceled)

### Claim 20

A dynamic lighting device, being characterized in that the device comprises
at least two lamps and a base,
the lamps have their projective images on the base not fully coinciding with each other,
the lamps (100b) are connected to their respective paired flexible stalks,
the flexible stalks are configured to rotate with respect to the base,
when each of the flexible stalks rotates with respect to the base, due to the gravity of the connected lamp, its own gravity and the centrifugal force it is subject to, the flexible stalk undergoes dynamic bending deformation and performs random movements;
wherein the top surface of the base is provided with a solar panel, and the solar panel is electrically connected to a power storage assembly through a mainboard.
