[0034] Existing lighting atmosphere effects are generally achieved by adding lighting accessories to lamps. In order to achieve dynamic optical effects, the existing lighting atmosphere effects need to be adjusted by a motor to drive the slide of the lighting accessory. Therefore, it is necessary to install a battery in the lighting accessory. However, due to the large size of the battery, the overall size of the lighting accessory will also be large, and the portability is poor, which cannot meet the user's usage needs.
[0035] This embodiment provides a lighting accessory, namely a lighting system, which is small in size, portable, and can meet the user's dynamic lighting effect needs. The specific solution is described in the following embodiments.

[0038] In some embodiments, multiple light attachments 100 may be provided, and the housings of the multiple light attachments 100 may be coaxially arranged. Adjacent light attachments 100 may be connected to each other, allowing light emitted by the lamp to pass through multiple light attachments 100 in sequence. This allows the light emitted by the lamp to be optically processed by multiple light attachments 100 to produce different optical effects. This increases the diversity of dynamic optical effects produced by the light attachment 100, thereby meeting the different lighting effect requirements of users.
[0039] It should be noted that in some other embodiments, connectors are provided on the exterior of the housings of multiple light attachments 100, allowing the multiple light attachments 100 to be laterally joined together via the connectors on the exterior of the housings. The multiple light attachments 100 can be arranged in the same horizontal plane. Multiple lamps can be provided, each of which can provide light to the multiple light attachments 100. Furthermore, by joining the exteriors of the multiple light attachments 100, the overall illumination area of the multiple light attachments 100 can be increased.
[0040] In some embodiments, the lighting accessory 100 may include a housing 1. The housing 1 may be in the shape of a shell with a hollow interior. The housing 1 may be cylindrical.

Light emitted from the lamp can enter the light-transmitting channel 11 through the light inlet 12 and then be emitted through the light outlet 13.
[0041] It should be noted that, in some other embodiments, the housing 1 may be in a truncated cone shape or other shapes.

[0043] See also Figures 1 to 4 As shown, in some embodiments, the light accessory 100 may include a light effect assembly. The light effect assembly may be disposed within the housing 1. The light effect assembly may be disposed within the light transmission channel 11. The light effect assembly can adjust the lighting effect. When light emitted from the lamp enters the light transmission channel 11 through the light inlet 12, the light passes through the light effect assembly and is then emitted through the light outlet 13. The light effect assembly can adjust the light emitted by the lamp, so that different optical effects are produced after the light from the lamp passes through the light effect assembly.
[0044] In some embodiments, the light effect assembly may include a lens 2. The lens 2 may be disposed within the housing 1. The lens 2 may be disposed within the light transmission channel 11. The lens 2 may be used to adjust the lighting effects. When light emitted from the lamp enters the light transmission channel 11 through the light inlet 12, the light passes through the lens 2 and is then emitted through the light outlet 13. The lens 2 can be used to adjust the light emitted by the lamp, resulting in different optical effects after the light passes through the lens 2.
[0045] It should be noted that in some embodiments, lens 2 can be a concave lens, a convex lens, or a plane mirror with a textured or uneven surface. Lens 2 can also be a projected film or logo film; logo film, also known as pattern film or gobo film, can produce various patterns such as logos, patterns, and text through light. Materials include metal, copper, glass, and colored glass. Lens 2 can be replaced based on the desired optical effect, without limitation.
[0046] In some embodiments, the light effect assembly may include a turntable 3. The turntable 3 is rotatably disposed within the light-transmitting passage 11 of the housing 1. The turntable 3 may be annular. The lens 2 may be mounted on the turntable 3. The turntable 3 drives the lens 2 to rotate relative to the housing 1. As the lens 2 rotates, light emitted by the lamp passes through the lens 2 to produce different optical effects.
[0047] It should be noted that, in some other embodiments, the turntable 3 may be in a truncated cone shape or other shapes.
[0048] In some embodiments, a first flange 31 may be provided on the inner wall of the turntable 3. The first flange 31 may be annular. The first flange 31 may be formed by a top edge of the turntable 3 projecting inward. The lens 2 may be mounted on the first flange 31. The first flange 31 can improve the mounting stability between the lens 2 and the turntable 3.
[0049] In some embodiments, a receiving groove may be formed between the first flange 31 and the inner wall of the turntable 3. The lens 2 may be mounted in the receiving groove. The first flange 31 and the inner wall of the turntable 3 may constrain the lens 2 in the receiving groove, thereby improving the mounting stability between the lens 2 and the turntable 3.
[0050] In some embodiments, a bump may be provided on the sidewall of the receiving groove, and the bump may be used to clamp the lens 2 in the receiving groove, thereby improving the installation stability of the lens 2 in the receiving groove.
[0051] In some embodiments, a boss 14 may be provided on the inner wall of the housing 1. The boss 14 may be annular. The turntable 3 may be rotatably accommodated on the boss 14.
[0052] In some embodiments, the light effect assembly may include a motor 4. The motor 4 may be disposed within the housing 1. The motor 4 can drive the turntable 3 to rotate, thereby driving the lens 2 to rotate within the housing 1, thereby enabling the light emitted by the lamp to produce different optical effects after passing through the lens 2.
[0053] In some embodiments, the output end of the motor 4 may be provided with a first drive tooth. The outer wall of the turntable 3 may be provided with a second drive tooth. The second drive tooth is circumferentially arranged on the outer side of the turntable 3. The first drive tooth may be provided on the boss 14 and can mesh with the second drive tooth. When the motor 4 is in operation, the motor 4 can drive the turntable 3 to rotate via the first drive tooth, thereby driving the lens 2 to rotate within the housing 1, thereby enabling the light emitted by the lamp to produce different optical effects after passing through the lens 2.
[0054] In some embodiments, the housing 1 may include a base 15. The base 15 may be annular. The base 15 may cover the bottom opening of the housing 1. The inner wall of the base 15 may be provided with a second flange 151 projecting inward. The second flange 151 may be formed by a bottom edge of the base 15 projecting inward.
[0055] In some embodiments, the motor 4 can be mounted on the second flange 151 . The output end of the motor 4 can pass through the boss 14 from the second flange 151 so that the first driving teeth at the output end of the motor 4 can mesh with the second driving teeth on the turntable 3 .
[0056] It should be noted that, in some other embodiments, the motor 4 can be directly mounted on the boss 14 , so that the first driving teeth of the motor 4 can directly engage with the second driving teeth of the turntable 3 .
[0057] Figure 5 yes Figure 1 Cross-sectional view in another direction. Figure 6 yes Figure 5 Top view of .
[0058] See also Figures 1 to 6 As shown, in some embodiments, the lighting accessory 100 may include a thermoelectric generator 5. The thermoelectric generator 5 may be disposed within the light-transmitting channel 11. The thermoelectric generator 5 may be used to generate electricity and power the motor 4, thereby driving the motor 4 to rotate the turntable 3. The thermoelectric generator 5 may be a semiconductor thermoelectric generator. The thermoelectric generator 5 may be a power generation device that utilizes the Seebeck effect to directly convert the temperature difference between its two surfaces into electricity.
[0059] In some embodiments, the thermoelectric generator 5 may include a high-temperature side and a low-temperature side. The high-temperature side of the thermoelectric generator 5 may be located on the inner side of the thermoelectric generator 5. The low-temperature side may be located on the outer side of the thermoelectric generator 5. The high-temperature side may be connected to the light-transmitting channel. The low-temperature side may be located outside the light-transmitting channel 11 and connected to the housing 1. When light emitted by the lamp enters the light-transmitting channel 11, due to its high output power, the light emitted by the lamp can increase the temperature within the entire light-transmitting channel 11, thereby increasing the temperature of the high-temperature side, thereby creating a temperature difference between the high-temperature side and the low-temperature side, and thereby creating an electric potential difference between the high-temperature side and the low-temperature side, thereby enabling the thermoelectric generator 5 to generate current. The thermoelectric generator 5 may be electrically connected to the motor 4. The current generated by the thermoelectric generator 5 can drive the motor 4 to rotate the turntable 3, thereby enabling the light emitted by the lamp to produce different optical effects after passing through the lens 2. Furthermore, using the thermoelectric power generation chip 5 to power the motor 4 eliminates the need for batteries, thereby reducing the internal volume of the housing 1 and the overall size and weight of the lighting accessory 100. This makes it easier for users to carry the lighting accessory 100 and meets their needs. Furthermore, compared to using batteries to power the motor 4, the thermoelectric power generation chip 5 continuously generates electricity during the lamp's lighting period, and uses this energy to drive the motor 4, allowing the motor 4 to operate continuously without being limited by battery capacity.
[0060] In some embodiments, the thermoelectric power generation sheet 5 can be disposed on the second flange 151. The thermoelectric power generation sheet 5 can be abutted by a side surface of the second flange 151 close to the light outlet 13. The thermoelectric power generation sheet 5 can be disposed along the axis of the housing 1, so that when the light from the lamp can pass through the air inlet and illuminate the high-temperature side of the thermoelectric power generation sheet 5, the temperature of the high-temperature side can be increased.
[0061] In some embodiments, the inner edge of the second flange 151 is provided with a flange 152. The flange 152 can extend from the inner edge of the second flange 151 toward the light outlet 13. The thermoelectric generator 5 can be disposed outside the flange 152. The flange 152 can restrain the thermoelectric generator 5 on the second flange 151, preventing it from protruding beyond the second flange 151, thereby preventing light emitted by the lamp from striking the lower side. Furthermore, the flange 152 can limit the thermoelectric generator 5, improving its installation stability within the housing 1.
[0062] In some embodiments, the lighting accessory 100 may further include a capacitor 6. The capacitor 6 may be disposed within the housing. The capacitor 6 can be used to store and release electrical energy. The capacitor 6 can be connected to the thermoelectric generator 5. When current is generated in the thermoelectric generator 5, the current generated by the thermoelectric generator 5 flows into the capacitor 6, thereby storing the electrical energy generated by the thermoelectric generator 5. The capacitor 6 can be electrically connected to the motor 4. The electrical energy in the capacitor 6 drives the motor 4 to rotate, thereby driving the rotation of the turntable 3 and the lens 2. This enables the light emitted by the lamp to produce different optical effects after passing through the lens 2.
[0063] It should be noted that the electrical energy stored in capacitor 6 can be delivered to motor 4 immediately upon startup of the lamp, enabling motor 4 to quickly drive turntable 3 to operate, thereby improving the efficiency of lighting accessory 100. Without capacitor 6, the temperature within light-transmitting channel 11 is low upon startup, preventing thermoelectric generator 5 from directly generating electrical energy to drive motor 4. Consequently, after startup, motor 4 will not be able to promptly drive turntable 3, thus failing to meet the user's lighting efficiency requirements, thereby affecting the user experience.
[0064] In some embodiments, a capacitor compartment may be provided on the base 15. The capacitor compartment may be formed by a side of the base 15 away from the light outlet 13 being recessed toward the light outlet 13. The capacitor 6 may be accommodated in the capacitor compartment.
[0065] See also Figures 3 to 6 As shown, in some embodiments, the lighting accessory 100 may include a heat conductive sheet 7. The heat conductive sheet 7 may be disposed within the housing 1. The heat conductive sheet 7 may be disposed around the low-temperature side of the thermoelectric generator 5. One end of the heat conductive sheet 7 may extend away from the thermoelectric generator 5 and be connected to the housing 1, thereby allowing the thermoelectric generator 5 to be connected to the housing 1 via the heat conductive sheet 7, thereby improving the connection stability of the thermoelectric generator 5 within the housing 1. The heat conductive sheet 7 allows the low-temperature side to be closer to the outside temperature, thereby increasing the temperature difference between the high-temperature side and the low-temperature side of the semiconductor thermoelectric generator 5, thereby improving the power generation efficiency of the semiconductor thermoelectric generator 5.

[0067] See also Figures 1 to 9As shown, in some embodiments, a socket 16 may be provided on the side wall of the housing 1. The socket 16 may be provided at a location corresponding to the boss 14 of the housing 1. The turntable 3 may be removably mounted on the boss 14 via the socket 16. The turntable 3 may be installed into the housing 1 via the socket 16 and mounted on the boss 14. The socket 16 allows the lens 2 on the turntable 3 to be replaced, allowing the lens 2 to be replaced as needed, thereby increasing the diversity of the lighting effects of the lighting accessory 100 and meeting the user's lighting effect requirements in different scenarios.
[0068] In some embodiments, a slot can be formed between the boss 14 and the inner wall of the housing 1. A socket 16 can be provided on the sidewall of the slot. The turntable 3 can be removably mounted in the slot via the socket 16. The boss 14 and the inner wall of the housing 1 can restrain the turntable 3 in the slot, thereby improving the stability of the turntable 3 within the slot.
[0069] In some embodiments, the lighting accessory 100 may include a bracket 8. The bracket 8 is removably mounted within the housing 1. The bracket 8 may be annular. The bracket 8 may be removably mounted on the boss 14. The bracket 8 may be removably mounted within the slot. The bracket 8 may be provided with a light outlet 81, allowing light emitted by the lamp to sequentially pass through the light inlet 12, the light outlet 81, and finally exit through the light outlet 13.
[0070] In some embodiments, the inner wall of the bracket 8 is provided with an annular ridge 82 projecting inward. The turntable 3 is rotatably mounted on the ridge 82, thereby allowing the turntable 3 to be rotatably mounted on the bracket 8. When the turntable 3 is mounted on the bracket 8, the lens 2 covers the light outlet 81, allowing light from the lamp to pass through the light inlet 12, the light outlet 81, the lens 2, and finally be emitted from the light outlet 13.
[0071] In some embodiments, a mounting groove 83 may be formed between the flange 82 and the inner wall of the bracket 8. The turntable 3 is rotatably disposed in the mounting groove 83. The turntable 3 may be restrained in the mounting groove 83 by the inner wall of the bracket 8 and the flange 82, thereby improving the stability of the installation between the turntable 3 and the bracket 8.
[0072] In some embodiments, the bracket 8 can be detachably mounted on the boss 14 via the socket 16. When the bracket 8 is mounted on the boss 14 via the socket 16, the boss 14 on the bracket 8 can be supported on the end of the thermoelectric generator 5 near the light outlet 13, thereby improving the stability of the bracket 8 within the housing 1.
[0073] In some embodiments, a through hole 84 may be formed on the side wall of the bracket 8. The through hole 84 may be formed on the side wall of the mounting slot 83. When the turntable 3 is installed in the mounting slot 83 of the bracket 8, the outer side wall of the turntable 3 can be exposed through the through hole 84. When the bracket 8 is installed on the boss 14 via the socket 16, the output end of the motor 4 can contact the outer side wall of the turntable 3 through the through hole 84, thereby driving the turntable 3 to rotate within the mounting slot 83 of the bracket 8.
[0074] In some embodiments, a handle 85 may be provided on the outer sidewall of the bracket 8. The user can use the handle 85 to insert the bracket 8 from the socket 16 to the boss 14. When the bracket 8 is installed on the boss 14, the handle 85 may be exposed outside the socket 16, allowing the user to remove the bracket 8 from the socket 16 using the handle 85. This makes the bracket 8 more convenient to remove and install.
[0075] See also Figures 3 to 9 As shown, in some embodiments, a pressure plate 17 can be fixed to one end of the housing 1 near the light outlet 13. The pressure plate 17 can be arranged at intervals above the boss 14. The pressure plate 17 can be annular. The pressure plate 17 can be covered at the light outlet 13. An opening is provided in the middle of the pressure plate 17. The diameter of the opening in the middle of the pressure plate 17 can be smaller than the diameter of the turntable 3. When the bracket 8 can be arranged on the boss 14 through the socket 16, the pressure plate 17 can be arranged above the bracket 8, and the pressure plate 17 can abut against the top surface of the turntable 3, and then the bracket 8 can be limited between the pressure plate 17 and the boss 14 to limit the movement of the turntable 3 in the axial direction of the housing 1, thereby further improving the stability of the bracket 8 inside the housing 1.
[0076] In some embodiments, the pressing plate 17 and the boss 14 may be fixedly connected by bolts, thereby improving the installation stability of the pressing plate 17 and the housing 1 .
[0077] It should be noted that, in some other embodiments, the pressing plate 17 may also be directly bonded to the inner wall of the housing 1 .
[0078] In some embodiments, a light-transmitting cover 18 may be provided on the housing 1. The light-transmitting cover 18 may cover the light outlet 13. After the light emitted by the lamp is emitted through the light outlet 13, it can be processed by the light-transmitting cover 18 for light effect.
[0079] In some embodiments, the light-transmitting cover 18 can be a plane mirror, and the light emitted from the light outlet 13 of the lamp can be emitted through the plane mirror. The plane mirror can protect the components inside the housing 1 and prevent external debris from entering the housing 1 through the light outlet 13.
[0080] It should be noted that the light shield 18 may be an optical lens. The light emitted by the lamp is optically processed by the lens 2 and then emitted from the light outlet 13. It is then refracted twice by the light shield 18, so that the light can be superimposed with different optical effects.
[0081] It should be noted that the light-transmitting cover 19 may also be a slide film or a logo film, which can adjust the outline and shape of the final emitted light.
[0082] In some embodiments, the pressing plate 17 may be a magnetic member. The pressing plate 17 may be made of ferromagnetic material. A magnet may be provided on the light-transmitting cover 18. The light-transmitting cover 18 may be directly magnetically attracted to the pressing plate 17 so that the light-transmitting cover 18 is fixed to the pressing plate 17.
[0083] In some embodiments, multiple lighting accessories 100 are coaxially arranged along the axis of the housing. The lighting accessory 100 that is closest to the lamp and connected to the lamp is the bottom lighting accessory. The lighting accessories adjacent to the bottom lighting accessory have a first magnetic block on their bases, and a second magnetic block on their pressure plates. This allows two adjacent lighting accessories 100 to be magnetically connected via the first magnetic block on their bases and the second magnetic block on their pressure plates.
[0084] It should be noted that, in some other embodiments, the light-transmitting cover 18 and the pressing plate 17 may be connected by bolts or other means.
[0085] In some embodiments, the pressing plate 17 may be equipped with a magnetic adsorption component. When the magnetic adsorption component needs to be equipped, the light-transmitting cover 18 may be removed from the pressing plate 17 and the magnetic adsorption component may be directly equipped on the pressing plate 17 .
[0086] See also Figures 3 to 9 As shown, in some embodiments, the housing 1 is provided with a mounting member 19 at one end of the light inlet 12. The mounting member 19 can be detachably mounted at the light inlet 12 of the housing 1. The mounting member 19 can be fixed to the light inlet 12 of the housing 1 by bolts.
[0087] In some embodiments, when a card slot is provided on the lamp, a bayonet that cooperates with the card slot can be provided on the mounting member 19, and then the lamp can be installed on the mounting member 19 through the cooperation between the card slot and the bayonet, and then the lamp can be installed at the light inlet 12 of the outer shell 1, so that the light emitted by the lamp can enter the light-transmitting channel 11 through the light inlet 12.
[0088] In some embodiments, when a magnetic part is provided on the lamp, a magnetic part can be provided on the mounting part 19, and then the lamp can be installed on the mounting part 19 through magnetic attraction between the magnetic part on the mounting part 19 and the magnetic part on the lamp, and then the lamp is installed at the light inlet 12 of the outer shell 1, so that the light emitted by the lamp can enter the light-transmitting channel 11 through the light inlet 12.
[0089] In some embodiments, the adjacent lighting accessories 100 that are closer to the lamp are called lower lighting accessories 100, and the lighting accessories 100 that are farther from the lamp are called upper lighting accessories 100. When the adjacent lighting accessories 100 are spliced along the axis of the housing 1, the light-transmitting cover 18 on the lower lighting accessory 100 can be removed, and the magnetic attraction between the pressure plate of the lower lighting accessory 100 and the magnetic attraction component on the mounting part of the upper lighting accessory 100 can be used to achieve magnetic fixation between the lower lighting accessory 100 and the upper lighting accessory 100, thereby achieving splicing of the adjacent lighting accessories 100 along the axis of the housing 1.
[0090] It can be seen from the above technical solution that the present invention has at least the following advantages and positive effects:
[0091] The present invention provides a lighting accessory 100 and a lighting system. The lighting accessory 100 may include a housing 1, a light effect assembly, and a thermoelectric generator 5. The housing 1 is hollow and defines a light passage 11. A light inlet 12 and a light outlet 13 are provided at either end of the housing 1, communicating with the light passage 11. The light inlet 12 is used to mount a lamp, and light emitted by the lamp can be emitted through the light passage 11 and out of the light outlet 13. The light effect assembly includes a turntable 3 rotatably disposed within the housing 1, a lens 2 mounted on the turntable 3, and a motor 4 that drives the turntable 3. The thermoelectric generator 5 is disposed within the light-transmitting channel 11 and electrically connected to the motor 4. The inner and outer sides of the thermoelectric generator 5 are respectively a high-temperature side and a low-temperature side. The high-temperature side of the thermoelectric generator 5 corresponds to the light-transmitting channel 11, while the low-temperature side can be connected to the housing 1. Light emitted by the lamp can be irradiated on the high-temperature side, causing the temperature of the high-temperature side to rise, thereby creating a temperature difference between the high-temperature side and the low-temperature side, thereby generating an electric potential difference. This generates current to drive the motor 4 to rotate the turntable 3. The thermoelectric generator 5 can then operate the motor 4 within the light accessory 100, thereby driving the turntable 3 to rotate, causing the lens 2 within the turntable 3 to rotate. When the light emitted by the lamp passes through the lens 2 and is emitted from the light outlet 13, different light effects can be presented, achieving a dynamic optical effect. The use of the thermoelectric generator 5 can reduce the volume of the housing 1, thereby reducing the overall volume of the light accessory 100, making it easier for users to carry the light accessory 100 and meeting their usage needs.
