Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically a projection chandelier for home use. Background Technology

[0002] A chandelier is a high-end decorative lighting fixture that is suspended from the ceiling of an interior room.

[0003] A novel projection chandelier (CN115681864A) is existing technology. This existing technology includes a support plate, a drive mechanism, an image mechanism, and a wireless speaker mechanism. The support plate has a protective cylinder on its upper surface. The drive mechanism is located inside the protective cylinder and is used to rotate the chandelier. The image mechanism is located on the drive mechanism and is used to project the chandelier. The wireless speaker mechanism is located inside the protective cylinder and is used for wireless remote control and external playback of the chandelier. The pattern on the projection dome, illuminated by a variable light panel, can emit different colored patterns, enriching the lighting effect of the chandelier. A motor can control the rotation of the projection dome, making the pattern projected onto the ceiling dynamically change, thus making the chandelier visually more aesthetically pleasing. A Bluetooth module on the main control board can connect to a mobile phone via Bluetooth, allowing music to be played through a speaker. Combined with the rich visual effects, this enhances the ambiance. However, the distance between the projection dome and the variable light panel remains constant, meaning that during multiple rotations of the projection dome, only repeated projections can be achieved, resulting in a less than ideal visual effect for the chandelier. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a projection chandelier that solves the problem that the distance between the projection cover and the variable light panel in existing chandeliers does not change, resulting in repeated projections during multiple rotations of the projection cover and thus an unsatisfactory visual effect.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a projection chandelier, comprising a base, a mounting plate, a servo motor, projection lamps, and casters. A connecting bracket is fixedly connected to the top of the base. The mounting plate is positioned directly above the base, and the top of the connecting bracket is fixedly connected to the mounting plate. The servo motor is fixedly connected to the bottom of the base, and a lead screw is fixedly connected to the drive end of the servo motor. The lead screw passes through the base, and a support plate is threaded onto the outer surface of the lead screw. The support plate is located between the mounting plate and the base. Two projection lamps are fixedly connected to the top of the support plate, and the two projection lamps are respectively located on both sides of the lead screw. The front surface of the support plate is connected via a rotating... The shaft is rotatably connected to two movable rods, which are located on both sides of the lead screw. The end of each movable rod away from the support plate is rotatably connected to a limit block via a rotating shaft. The top of the base is fixedly connected to two limit guide rails. The bottom of each of the two limit blocks has a limit groove, and the limit guide rails are engaged inside the limit groove. A projection cover is installed inside the connecting bracket. Multiple counterweights are fixedly connected to the bottom of the projection cover. Multiple rollers are fixedly connected to the bottom of the multiple counterweights and are in contact with the top of the base. A fixing plate is fixedly connected to the top of the lead screw. An installation groove is opened in the inner top wall of the projection cover, and the top of the fixing plate is movably connected inside the installation groove.

[0008] Preferably, a decorative outer shell is fixedly connected to the bottom of the base, and the servo motor is located inside the decorative outer shell.

[0009] Preferably, the cross-sections of the limiting guide rail and the limiting groove are both inverted isosceles trapezoids.

[0010] Preferably, the cross-sectional shape of the projection mask is arc-shaped, and the center of the projection mask and the central axis of the lead screw are on the same straight line.

[0011] Preferably, the multiple counterweights are arranged in a circular array with the center of the projection cover as the center.

[0012] Working Principle: In use, the chandelier is installed on the ceiling using the mounting plate. Then, the servo motor and projection lamp are connected to a power source. During operation, the servo motor drives a lead screw to rotate, which in turn causes the projection dome to rotate via a fixed plate. This dynamically changes the pattern projected by the dome, improving the chandelier's performance. During the rotation of the projection dome, the support plate is limited by a movable rod, limit block, limit rail, and limit groove, allowing the lead screw to drive the support plate to move up and down. This changes the distance between the projection lamp and the projection dome on the support plate, causing the projection... The projected pattern is distorted, which helps to further enrich the projection effect. When the projection cover needs to be removed, since the projection cover is connected to the mounting slot and the screw rod through the fixing plate, the fixing plate can be lifted up to disengage from the mounting slot, which is convenient for cleaning the projection cover and for replacing the projection cover with one that can project different patterns. Furthermore, when the user is not used to dynamic projection, the position of the projection lamp and the projection cover can be adjusted by the servo motor to project a more aesthetically pleasing pattern from the user's perspective, thereby obtaining a better projection effect. It can be used with different projection covers. Finally, the servo motor is not activated when using the chandelier.

[0013] (III) Beneficial Effects

[0014] This invention provides a projection-enabled home chandelier. It has the following beneficial effects:

[0015] 1. This projection pendant light, through the setting of a servo motor, lead screw, support plate, projection lamp, movable rod, limit block, limit guide rail, and limit groove, can limit the projection lamp on the support plate. This allows the servo motor to drive the lead screw to move the projection lamp on the support plate up and down, thereby changing the distance between the projection lamp and the projection cover, causing the projected pattern to be distorted, which helps to further enrich the projection effect.

[0016] 2. This projection chandelier, through its fixed plate, mounting slot, projection cover, counterweight, and rollers, allows the servo motor to drive the screw to rotate the projection cover because the fixed plate on the screw can be inserted into the mounting slot on the projection cover. This enables the projection pattern to change dynamically, improving the chandelier's performance. Furthermore, since the projection cover is connected to the screw via the fixed plate and mounting slot, it is easy to install and remove the projection cover, making it convenient to clean and replace with different projection covers.

[0017] 3. This projection chandelier can project dynamic patterns without actually projecting them. Instead, it uses a servo motor to adjust the position of the projection lamp and the projection cover, allowing the projected pattern to be more aesthetically pleasing from the user's perspective, thus achieving a better projection effect. It is also compatible with different projection covers. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0023] like Figure 1-3As shown, this embodiment of the invention provides a projection chandelier, including a base 1, a mounting plate 3, a servo motor 5, projection lamps 8, and casters 14. A connecting bracket 2 is fixedly connected to the top of the base 1. The mounting plate 3 is positioned directly above the base 1, and the top of the connecting bracket 2 is fixedly connected to the mounting plate 3. The servo motor 5 is fixedly connected to the bottom of the base 1, and a lead screw 6 is fixedly connected to the drive end of the servo motor 5. The lead screw 6 passes through the base 1, and a support plate 7 is threaded onto the outer surface of the lead screw 6. The support plate 7 is located between the mounting plate 3 and the base 1. Two projection lamps 8 are fixedly connected to the top of the support plate 7, and the two projection lamps 8 are located on both sides of the lead screw 6. Two movable rods 9 are rotatably connected to the front surface of the support plate 7 via a pivot. Two movable rods 9 are located on both sides of the lead screw 6. The end of the movable rod 9 away from the support plate 7 is rotatably connected to the limit block 10 through a rotating shaft. Two limit guide rails 11 are fixedly connected to the top of the base 1. Limit grooves 16 are opened at the bottom of the two limit blocks 10. The limit guide rails 11 are snapped into the inside of the limit grooves 16. A projection cover 12 is set inside the connecting bracket 2. Multiple counterweights 13 are fixedly connected to the bottom of the projection cover 12. Multiple rollers 14 are fixedly connected to the bottom of the multiple counterweights 13. The multiple rollers 14 are in contact with the top of the base 1. A fixing plate 15 is fixedly connected to the top of the lead screw 6. An installation groove 17 is opened on the inner top wall of the projection cover 12. The top of the fixing plate 15 is movably connected to the inside of the installation groove 17.

[0024] A decorative outer shell 4 is fixedly connected to the bottom of the base 1. The servo motor 5 is located inside the decorative outer shell 4. The decorative outer shell 4 conceals the servo motor 5, making the lamp more aesthetically pleasing. The cross-sections of the limiting guide rail 11 and the limiting groove 16 are both inverted isosceles trapezoids. The inverted isosceles trapezoidal limiting guide rail 11 and limiting groove 16 make the limiting guide rail 11 fit better with the limiting groove 16 on the limiting block 10, thereby preventing the limiting block 10 from detaching from the limiting guide rail 11. The cross-sectional shape of the projection cover 12 is arc-shaped. The center of the projection cover 12 and the central axis of the lead screw 6 are on the same straight line, so that the servo motor 5 drives the lead screw 6 to drive the projection cover 12 to rotate circumferentially, thereby providing the projection effect of the projection cover 12. Multiple counterweights 13 are arranged in a circular array with the center of the projection cover 12 as the center. The counterweights 13 can balance the projection cover 12, making the lead screw 6 drive the projection cover 12 to rotate more stably.
