[0028] The present invention provides a ceiling lamp. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The drawings are only used to explain the structural principles and are not proportional to the actual products. The drawings only depict structures related to the invention points of this application, and some conventional structures are not specifically depicted. The terms "first", "second", etc. described herein are merely different names for similar structures for the convenience of explanation, and are not intended to limit this application.

[0030] First see Figure 1 A ceiling lamp comprises two lamp holders 91 and a mounting base 8, each lamp holder is connected to two hanging ropes 92; a lamp holder driving assembly is arranged in the mounting base corresponding to each lamp holder; each lamp holder driving assembly comprises a slide plate 7 arranged on the mounting base, and a slide plate driving device 1 for driving the slide plate to reciprocate along a straight line; a straight groove 80 is arranged at the bottom of the mounting base corresponding to each lamp holder; a threading hole 70 is arranged on each slide plate corresponding to each hanging rope, and a hanging rope winding device 2 is arranged on each slide plate corresponding to each threading hole.

[0031] In practical applications, each of the above-mentioned hanging ropes is provided with an electric wire (not shown in the figure) for electrically connecting with the lamp holder. Preferably, the above-mentioned lamp holder is provided with an LED lamp bead (not shown in the figure); in addition, other types of light sources may also be provided. Since the light source part is not the invention point of this application, it is not specifically elaborated and limited here.

[0032] Please continue reading Figure 1 The sliding connection between the slide plate and the mounting seat can be configured as follows: at least two slide blocks (not shown in the figure) are respectively provided at the bottom of each slide plate, and two slide rails 72 are respectively provided on the mounting seat corresponding to each slide plate; each slide block is respectively connected to the corresponding slide rail. The driving device drives the slide plate to move to change the horizontal position of the lamp head, so that the illumination range of the lamp head can be flexibly adjusted.

[0033] like Figure 2 As shown, further, each skateboard driving device 1 comprises a first motor 11 arranged on the skateboard, a first gear 12 arranged on the main shaft of the first motor, and a first rack 13 arranged on the mounting seat. The transmission by the gear rack ensures that the skateboard can move quickly and accurately; in addition, since the first motor is arranged on the skateboard instead of the mounting seat, the mounting seat has a compact structure.

[0034] Preferably, each first gear is a helical gear with the same specifications, and each first rack is a helical rack with the same specifications; the main shafts of the two first motors are in opposite directions. Since the helical gears and helical racks are set, the transmission is more stable; the main shafts of the two first motors are in opposite directions, that is, the skateboard driving devices are not set on the same side, so that the mounting seat bears the overall balance of the gravity of the two skateboard driving devices.

[0035] See also Figure 3 and Figure 4 Furthermore, each rope winding device includes a first bracket 21, a second bracket 23, and a second motor 25; the first bracket is provided with a guide wheel 22, and the second bracket is provided with a winding drum 24; the main shaft of the second motor is provided with a first bevel gear 251, and the winding drum is connected with a second bevel gear 252; the axis of the first motor is perpendicular to the axis of the corresponding winding drum. The above-mentioned guide wheel and winding drum can rotate respectively; each rope passes through the corresponding guide wheel and then is wound on the winding drum. The rotation of each second motor can realize the winding or releasing of the corresponding rope, so as to flexibly adjust the illumination angle of the lamp head.

[0036] like Figure 4 As shown, preferably, the first bracket includes two vertical rods 212 and a round rod 211, and the guide wheel is provided with a round through hole 220, and the round rod passes through the round through hole; the round rod and the round through hole of the guide wheel are clearance-matched, so that the guide wheel can move along the length direction of the round rod. Since the guide wheel can move along the length direction of the round rod, the guiding effect can be further improved.

[0037] like Figure 3 As shown, further, a spiral groove 240 is provided on the outer wall of the winding drum 24. This arrangement enables the sling rope to be evenly wound around the winding drum along the spiral groove when the winding drum reels the sling rope.

[0038] like Figure 1 As shown, further, each threading hole 70 is located on the same straight line; the main shafts of the two second motors on the same slide are oriented in opposite directions. Since each threading hole is located on the same straight line, the two lamp heads are located on the same straight line, so it is easier to adjust the irradiation range during use. The main shafts of the two second motors on the same slide are oriented in opposite directions, so that the weight borne on the top of the slide is evenly distributed as a whole instead of being distributed on one side of the slide, making the slide move more smoothly.

[0039] like Figure 5 As shown, further, a mounting seat with a simple structure is provided here: the mounting seat 8 includes a bottom plate 81, a top plate 82, two side plates 83 and two end plates 84; a plurality of connecting holes 820 (attached Figure 5 Only the connection hole at one end of the top plate is observed, but in fact the other end of the top plate is also provided with a connection hole). The straight groove mentioned above is provided on the bottom plate, and the two slide plates are mounted on the bottom plate. The connection hole provided on the top plate is used to connect with the ceiling, thereby fixing the mounting base on the ceiling.

[0040] Preferably, both lamp caps are arc-shaped and have the same specifications. The two lamp caps are arranged in an arc shape, which can play a focusing role; in addition, the two arc-shaped lamp caps can be combined into more forms. Figures 6 to 9 A variety of lamp head combinations are shown (there can be more types in actual applications) to meet different lighting needs.

[0041] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the present invention.
