Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figures 2 to 7This utility model provides a technical solution: a lighting device for bedroom furniture, including a support ring 1. Multiple movable slots 2 arranged in a circular array are provided on the outer side of the support ring 1. Support frames 3 are movably installed on the inner sides of each of the multiple movable slots 2. A lampshade 4 is fixedly connected to the outer side of each of the multiple support frames 3. The lampshade 4 is made of kraft paper, folded in a W-shape and connected end-to-end to form a cylinder. A metal wire for shaping is provided at the middle of the inner side of the lampshade 4. A transmission slot 5 is provided on one side of the support ring 1. A driven gear 6 is rotatably connected to the inner side of the transmission slot 5. A transmission cable 7, which is a steel wire rope with a diameter of 1 mm, passes through and is movably connected to the inner side of the support ring 1. The two ends of the transmission cable 7 are fixedly connected to the two ends of the driven gear 6, respectively. The transmission cable 7 also passes through and is fixedly connected to multiple supports 3. A bracket 8 is fixedly connected to the inner side of the support ring 1. A motor 9 is fixedly installed on one side of the upper end of the bracket 8. One end of the output shaft of the motor 9 is fixedly connected to the driving gear 10. A moving groove 11 is opened on the inner side of the bracket 8. The moving groove 11 corresponds to the position of the transmission groove 5. A toothed belt 12 is installed on the inner side of the moving groove 11. Both ends of the toothed belt 12 are simultaneously meshed with the driven gear 6 and the driving gear 10. A lamp holder 13 is fixedly connected to the inner side of the bracket 8. A light bulb 14 is movably installed at the bottom end of the lamp holder 13. The bulb 14 is an LED bulb. A support rod 15 is fixedly connected to the top of the lamp holder 13, and a base 16 is fixedly connected to the other end of the support rod 15. The support rod 15 is made of flexible metal tubing. Through the driven gear 6, it can drive the transmission cable 7 to rotate, thereby simultaneously driving multiple supports 3 to rotate up and down. This allows the lampshade 4 to deform, transforming into a frustum shape that is smaller at the top and larger at the bottom, or vice versa. It can be adjusted according to usage needs to achieve either focused or diffused light effects. It can be adjusted freely during use. During operation, the motor 9 drives the drive gear 10 to rotate, thereby... The driven gear 6, connected by the toothed belt 12, rotates, which in turn drives the transmission cable 7 to rotate. The transmission cable 7 simultaneously drives multiple supports 3 to rotate. The rotation of the multiple supports 3 in different directions causes the lampshade 4 to deform into different shapes. When the bottom of the lampshade 4 becomes larger, more light can shine downwards, making the illuminated area smaller and brighter, while other areas remain unaffected. When the top of the lampshade 4 becomes larger, more light can shine upwards to the roof and reflect the light, thus illuminating the entire room. This can be adjusted according to different usage needs.
