The utility model will be described in detail below in combination with the drawings.

[0025] Please refer to Figures 1-6 , a specific implementation of a ceiling lamp, comprising a fixed seat 1, a lamp 3 and a retraction assembly 4, the lamp 3 comprises three light bars, and the three light bars are horizontally arranged in linear array structure, four connecting cables 2 are arranged between the fixed seat 1 and the three light bars for connection and fixation, the number of the retraction assembly 4 is consistent with the number of the connecting cable 2, the retraction assembly 4 comprises a receiving device 41 and a driving part 42, the inside of the receiving device 41 is a rotatable winding drum 411, the surface of the winding drum 411 is provided with a threaded groove structure, one end of the connecting cable 2 is fixedly connected with the winding drum 411, and the driving part 42 is used to drive the winding drum 411 to rotate so that the connecting cable 2 is wound in the middle of the winding drum 411, and one end of the connecting cable 2 is fixedly connected with the corresponding light bar top end face.

[0026] On one hand, the lamps 3 are driven by the contraction assemblies 4 in the fixing bases 1 above, and the lamps 3 can be effectively lifted by the connecting cables 2 to adjust the height of the lamps 3. On the other hand, the lamps 3 include a plurality of lamp strips, and the contraction assemblies 4 of the parts can be driven to effectively lift the corresponding parts of the lamp strips to adjust the illumination angle and range of the lamp strips. Meanwhile, different visual effects can be formed by the shape change of the lamp strips, and the lamps have variable appearances.

[0027] Specifically, as shown in Figure 2 and Figure 3 , the driving part 42 includes a stepping motor 421, a rotating shaft 423 and a worm wheel 424, the output shaft of the stepping motor 421 is a worm 422, one end of the rotating shaft 423 is fixedly connected with the center of the winding drum 411, the worm wheel 424 is arranged at the middle part of the rotating shaft 423, and the worm 422 is in meshing transmission with the worm wheel 424.

[0028] Further, the inside of the fixing base is also provided with a limiting assembly 5, the limiting assembly 5 includes a sliding bracket 51, a push block 52 and a limiting switch 53, the push block 52 is movably arranged in the inside of the sliding bracket 51, the worm 422 is threadedly connected with the middle part of the push block 52, the limiting switch 53 is arranged at one end of the worm 422, and the push block 52 can abut against the limiting switch 53 through the worm 422. When the stepping motor 421 drives the worm 422 to rotate, the push block 52 can move linearly along the sliding bracket 51 due to the threaded connection between the worm 422 and the push block 52. When the lamps 3 are lifted to the topmost part, the limiting switch 53 on one side can be triggered by the push block 52, so that the stepping motor 421 is stopped.

[0029] Further, the storage device 41 also includes a plurality of guide rods 412, the plurality of guide rods 412 are arranged in parallel with the axial direction of the winding drum 411, and one guide rod 412 near the winding drum 411 is sleeved with a movable guide wheel 413. One end of the connecting cable 2 is sequentially fixedly connected with the winding drum 411 through the guide rod 412 and the guide wheel 413. When the winding drum 411 contracts the connecting cable 2, the middle part of the connecting cable 2 can move under the guidance of the guide wheel 413, so that the connecting cable 2 is prevented from being tangled and knotted when being wound.

[0030] Specifically, as shown in Figure 4 and Figure 5As shown, several light strips are composed of a main light strip 31 and two auxiliary light strips 32. The lengths of the two auxiliary light strips 32 are the same, and the lengths of the two auxiliary light strips 32 are less than the length of the main light strip 31. The two auxiliary light strips 32 are respectively arranged on both sides of the main light strip 31. The middle part of the main light strip 31 is a connecting part 311, and the two auxiliary light strips 32 are arranged in a centrally symmetrical structure around the connecting part 311 at both ends of the main light strip 31.

[0031] The connecting part 311 has fixing holes 312 on both sides. Each of the two auxiliary light strips 32 has a connecting pin 321 matching the fixing hole 312 near the side wall of the connecting part 311. The two auxiliary light strips 32 are connected to the fixing hole 312 via the connecting pin 321, and the auxiliary light strips 32 can swing around the main light strip 31 with the connecting pin 321 as the center. This swingable structure formed between the auxiliary light strips 32 and the main light strip 31 via the connecting pin 321 and fixing hole 312 is a key structure for changing the shape of the light strips.

[0032] At the same time, such as Figure 1 As shown, the side wall of the light strip is provided with several control buttons 5, which are, from left to right, for controlling the color temperature, for controlling the deformation of the light fixture 3, for controlling the descent of the light fixture 3, and for controlling the ascent of the light fixture 3. Preferably, the ceiling light fixture can be equipped with a remote control, which can control the deformation, ascent, descent, on / off and color temperature changes of the light fixture 3.

[0033] Specifically, the working process of adjusting the height of a ceiling light fixture is as follows: the stepper motors 421 in the four sets of retraction components 4 are driven simultaneously, causing the connecting cable 2 to be close to one end of the fixed base 1, and then pass through the guide rod 412 and the guide wheel 413 in sequence to retract into the drum 411. At the same time, the surface of the drum 411 has a threaded groove structure, so the retraction trajectory of the connecting cable 2 is horizontal. At this time, the connecting cable 2 can slide along the middle of one of the guide rods 412 through the guide wheel 413, thereby avoiding the connecting cable 2 from getting tangled and knotted. At the same time, the four connecting cables 2 can simultaneously lift the main light strip 31 and the two auxiliary light strips 32, respectively, to complete the process of adjusting the height of the ceiling light fixture.

[0034] Specifically, the working process of adjusting the appearance, illumination angle, and range of a ceiling light fixture is as follows: Driven by the retraction components 4 located at the outermost ends of the fixing base 1, the connecting cable 2 of the auxiliary light strip 32 retracts upwards, causing the end of the auxiliary light strip 32 away from the connecting part 311 of the main light strip 31 to swing upwards. Simultaneously, the auxiliary light strip 32 can swing outwards along the connecting pin 321, expanding the illumination angle and range of the light fixture 3. In terms of appearance, the shape of the auxiliary light strip 32 can be adjusted by driving the retraction range of the corresponding retraction components 4. When combined with the main light strip 31, the auxiliary light strip 32 can create different visual effects and has a variety of appearances, such as…Figure 6 as shown.
