Description

Technical Field

[0001] The present invention relates to a lighting fixture, and more particularly to a lighting fixture based on Flasher origami. Background Art

[0002] Origami art, as a traditional art carrying profound cultural heritage, has high artistic value and application value due to its unique form and structural characteristics. With the wide application of origami art in various fields, origami art has returned to the public's vision and become a new direction for innovative research in the design field. Similarly, in the field of furniture design, origami art has also attracted wide attention with its unique charm and has given rise to some furniture designs with origami art characteristics. However, the innovation of origami art in furniture design is still insufficient at present, and many design works still remain at the conceptual level, lacking practical feasibility and the possibility of implementation.

[0003] With the progress of society, the continuous improvement of science and technology, and the continuous improvement of people's material living standards, the pursuit of beauty in life has become stronger. Therefore, many lighting fixtures with exquisite appearance and various shapes have emerged on the market to improve the aesthetic feeling of people's living environment.

[0004] In the current technical field, traditional lighting devices generally adopt static structure design, resulting in the fixed emission direction and light intensity distribution of their light sources, which cannot be dynamically adjusted according to the needs of actual application scenarios. This design limitation restricts the adaptability and flexibility of the light source, and thus affects the lighting efficiency and the effective utilization of energy. Specifically, once the light source directionality and illuminance distribution of traditional lighting fixtures are determined during the manufacturing process, they cannot be adjusted subsequently by physical or electronic means, which appears rather rigid in the face of changing lighting requirements. Therefore, traditional lighting fixtures not only limit their performance in specific application scenarios but also may lead to unnecessary waste of energy.

[0005] Currently, the lighting fixtures on the market have the following problems: 1. Poor balance between decoration and functionality; 2. Small volume change; 3. Poor flexibility and adaptability; 4. Poor portability; 5. Poor energy efficiency. Summary of the Invention

[0006] The purpose of the present invention is to derive a sunflower lighting fixture through Flasher origami design and provide a more unique visual effect for the lighting fixture, enabling it to adapt to different lighting requirements and environmental conditions.

[0007] A lamp based on Flasher origami, including a lampshade. The lampshade presents a regular hexagon shape in the unfolded state and is composed of N crease units, where N≥3. These crease units are designed based on the Flasher pattern principle and can fold the lampshade into a columnar structure. A central axis passes through the middle of the lampshade, and one end of the central axis is fixed to a circular bottom plate. A first pulley drive control part is arranged at the position where the top of the central axis cooperates with the lampshade, a dimming module is arranged above the center position of the circular bottom plate, and a second pulley drive control part is arranged on the outer periphery of the center position of the circular bottom plate.

[0008] Preferably, the lampshade of the present invention is an origami part composed of several pairs of crease units. The diagonal creases extending from the connecting vertices of each crease unit respectively form mountain creases and valley creases, and the angles with the vertical straight creases are α° and α / 2° respectively. Each crease unit is centered on the central axis.

[0009] Preferably, soft light cloth and plastic film are respectively attached to both sides of each crease unit of the present invention.

[0010] Preferably, the first pulley drive control part of the present invention is: a large pulley and a small pulley are respectively arranged at the position where the top of the central axis cooperates with the lampshade. The large pulley is arranged at the top of the central axis, and a belt is arranged between the large pulley and the small pulley.

[0011] Preferably, the dimming module of the present invention includes an LED light source arranged above the center position of the circular bottom plate. The edge of the acrylic disc is processed by perforation, and the LED light source is fixed around the disc with nylon ties. After being connected to the acrylic disc, the LED light source is arranged above the large pulley in the middle position between the origami main body and the circular bottom plate (that is, placed above the slide rail), and the LED light source is externally connected to a power supply. An acrylic disc connected to the central axis is arranged above the LED light source 2, and a dimming circuit board is arranged below the small pulley.

[0012] Preferably, the second pulley drive control part of the present invention is: several slide rails are installed on the circular bottom plate in an equidistant circumferential array. The placement angle between two adjacent slide rails is 360° / N. One end of an aluminum alloy rod with a pulley is arranged on each slide rail, and the other end of the aluminum alloy rod is connected to the origami part.

[0013] Preferably, holes matching the screws are arranged on each crease unit constituting the origami part of the present invention, and the screws are located at one end of the aluminum alloy rod.

[0014] Compared with the prior art, the lighting fixture system of the present invention is an illumination device mainly based on a new origami structure derived from the Flasher pattern design. Different from the fixed form of traditional lighting fixtures, the present invention has higher flexibility and adaptability and can be folded and unfolded in various spatial environments. Based on the characteristics of a single degree of freedom, the lighting device of the present invention can realize the conversion from a planar form to a compact cylindrical form within a limited space. The foldable and unfoldable structure can change its own size in different environments to achieve operations in complex environments, save the space volume of storage devices during transportation, and achieve the purpose of reducing transportation costs. The main origami material of the present invention is soft light cloth. Compared with lighting fixtures with rigid structures, it has strong adaptability, simple structure, high flexibility, and significantly reduced manufacturing costs, and can be mass-produced.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1-6As shown, a lamp based on Flasher origami includes a lampshade, which presents a regular hexagonal shape in an unfolded state and is composed of N pairs of crease units, N ≥ 3; these crease units are designed based on the Flasher pattern principle and can enable the lampshade to be folded into a columnar structure; a central axis is passed through the middle of the lampshade, and one end of the central axis is fixed to a circular base plate; a first pulley drive control part is arranged at a position where the top of the central axis matches the lampshade, a dimming module is arranged on the upper part of the center position of the circular base plate, and a second pulley drive control part is arranged on the periphery of the center position of the circular base plate.

[0023] like Figure 1 , Figure 2 As shown, the lampshade is an origami part composed of several pairs of crease units 1. The crease unit 1 of the Flasher origami model is derived from the typical Miura crease design. The left oblique crease 101 and the right oblique crease 104 connecting the vertices of the crease unit are mountain creases, and the remaining oblique creases 102 and 103 are valley creases. The angles with the vertical straight line creases are α° and α / 2°. The crease unit is fan-shaped by setting the oblique straight line crease angle 1 / 2[π-π(n-2) / n]. The crease unit takes the central axis as the center of the circle, and the circumference array has N units. The crease pattern forms the origami body of the lamp after folding and unfolding.

[0024] A diffuser cloth and a plastic film are attached to the two sides of each crease unit respectively.

[0025] like Figure 3 , Figure 4 As shown, the first pulley driving control part is: a large pulley and a small pulley are respectively arranged at the position where the top of the central axis matches the lampshade, the large pulley is arranged at the top of the central axis, and a belt is arranged between the large pulley and the small pulley.

[0026] like Figure 3 , Figure 4 As shown, the dimming module includes an LED light source 502 arranged at the upper center of the circular bottom plate, the edge of the acrylic disc 501 is perforated, and the LED light source is fixed around the disc with a nylon tie, and the LED light source 502 is connected to the acrylic disc 501 and arranged above the origami body and the large pulley in the middle of the circular bottom plate (that is, placed above the slide rail), and the LED light source 502 is connected to an external power supply; an acrylic disc 501 connected to the central axis is arranged above the LED light source 502, and a dimming circuit board is arranged below the small pulley. By manually rotating the large pulley handle above the origami body, the central axis is driven to rotate, thereby realizing the rotation of the large pulley below the origami body, and the small pulley is driven to rotate through the transmission of the belt to rotate the shaft of the dimming module, so that the circuit runs, thereby realizing the brightness adjustment of the light.

[0027] like Figure 3 , Figure 4As shown, the second pulley drive control part is: a number of slide rails installed in a circumferential array at equal intervals on a circular bottom plate, with an included angle of 360° / N between adjacent slide rails. An aluminum alloy rod with a pulley at one end is arranged on each slide rail, and the other end of the aluminum alloy rod is connected to the origami part.

[0028] As Figure 3 , Figure 4 shown, holes adapted to screws are provided on each crease unit constituting the origami part, and the screws are located at one end of the aluminum alloy rod.

[0029] Referring to Figure 3 and Figure 4 , the present invention provides a Flasher origami lamp device, including:

[0030] A first pulley drive control part 2 and a second pulley drive control part 4, including a small pulley 201, a large pulley 202 and a belt 203 respectively installed between them. Six slide rails 403 are installed in a circumferential array at equal intervals at the reserved installation positions on the disc, with an included angle of 360 / N° between adjacent slide rails. The aluminum alloy rod 402 is driven by a pulley handle and is connected to the origami part 3 through a screw 401.

[0031] The origami part 3 is installed through the reserved positions on the disc and six slide rails 403 installed in a circumferential array at equal intervals, with an included angle of 360 / N° between adjacent slide rails. The origami part 3 is punched at the central hub crease part and is connected to the disc base through a central shaft and pulleys. Six aluminum alloy rods 402 are connected and fixed to the origami part 3 through screws 401. The origami part 3 is connected to the upper plane of the disc base in the control part through a central shaft and pulleys. The pulleys control the movement of the aluminum alloy rod 402 through circular motion, thereby controlling mechanical movements such as the contraction and expansion of the origami part 3.

[0032] The dimming part 5 includes a pulley 201, a large pulley 202, a dimming circuit board 204, and a belt 203 installed between the small pulley 201 and the large pulley 202. Six slide rails 403 are installed on the disc in a circumferential array at equal intervals by screws. The included angle between two adjacent discs is 360 / number of tracks °. The dimming circuit board is installed at the reserved position of the dimming module 204. Screws are installed at the punching positions at the end of the origami part 3. The origami part 3 is punched at the central hub and forms a shaft-passing channel after folding. A central shaft is connected to the center of the disc through the holes reserved by the pulley. Through the circumferential movement of the pulley, the movement of the six surrounding slide rails is controlled to realize the folding and unfolding of the origami part 3. The LED light source 502 is arranged above the large pulley at the middle position between the origami main body and the circular bottom plate (that is, above the slide rail) after being connected to the acrylic disc 501. The LED light source 502 is externally connected to a power supply. An acrylic disc 501 connected to the central shaft is arranged above the LED light source 502. The dimming circuit board is placed in the bracket and fixed to the bottom disc by screws. The small pulley 201 is placed above. The small pulley is concentric with the rotating shaft of the dimming module. By manually rotating the handle of the large pulley above the origami main body, the rotation of the central shaft is driven, and then the rotation of the large pulley below the origami main body is realized. The rotation of the small pulley is driven through the transmission of the belt to make the rotating shaft of the dimming module rotate, so that the circuit operates, thereby realizing the adjustment of the brightness of the light.

[0033] In this example, the driving part includes an aluminum alloy rod. The adopted aluminum alloy rod has plasticity, workability, corrosion resistance, convenience, aesthetics, and light weight, and is used to drive the mechanical movement of the origami main body in this example.

[0034] In this example, the material of the origami part 3 is composed of a paper with soft light cloth and plastic film attached to both sides. The soft light cloth improves the light transmittance of the origami structure, and the plastic film improves the toughness of the origami structure, making the recovery ability of the origami structure enhanced, and also improving the strength of the paper, reducing the weight of the paper, enhancing its durability, and extending the service life.

[0035] Refer to Figure 4 And Figure 5 , in this example, Figure 5 is the initial state of the lamp. In the control system, the pulleys drive the slide rails 403 to move linearly respectively, control the inward or outward displacement of the six aluminum alloy rods 402, and the pulleys drive the screws 401 to control the force direction on the origami part 3 through the slide rails 403, thereby controlling the origami part 3 to realize mechanical movements such as contraction and unfolding. For example, Figure 6 , the origami part 3 is in the unfolded state.

[0036] The present invention provides a lamp with a Flasher pattern as the main structure. The main structure of the lamp presents a regular hexagonal cardboard shape in an unfolded state, and is composed of N pairs (N>3) of crease units. These crease units are designed based on the principle of the Flasher pattern and can fold the cardboard into a columnar structure. This design allows the lamp to switch between folding and unfolding, achieving effective use of space and unique lighting effects. The core structure of the lamp system adopts the Flasher pattern, the lampshade is made of special materials, and the back is covered with a layer of plastic film to enhance durability. A small hole is provided in the center of the circular bottom plate of the lamp to fix the central axis and the pulley to achieve structural stability. A pulley device is installed on the top to allow the central axis to rotate freely. The top pulley drives the central axis to rotate, so that the matching bottom pulley rotates to drive the slider to slide, so that the origami is unfolded, thereby adjusting the direction of the light. Six equal-length aluminum alloy rods, the ends of which are punched and screwed, are combined with six sets of slide rails fixed to the bottom plate, so that the rods can slide freely along the rails, providing flexible adjustment capabilities for the lamp. After being punched, the acrylic disc is used as a light bracket. The LED light source and other components are fixed on it by iron wire to ensure the stability and safety of the light source. The dimming circuit board is installed on the above-mentioned circular base plate through a bracket that adapts to its size, and is connected to the pulley mentioned above and fixed to the base plate by screws. The bottom pulley of the central axis is connected to the pulley installed on the dimming module through a belt. The central axis is driven to rotate by manually rotating the top pulley, so that the bottom pulley rotates synchronously, and the pulley matched with the dimming module is driven by the belt to rotate, which can drive the dimming module to rotate, realize precise light adjustment, and provide dimming function for the lamp. The lampshade of the lamp is fixed with a metal wheel, and small holes are punched on the edge of the lampshade and fixed with screws, which enhances the overall structural strength of the lamp. In addition, the lamp system also adds a touch module, which allows users to control the switch of the lamp through simple touch operations, improving the user experience.

[0037] The lamp of the present invention uses Flasher pattern origami as the main body of the device by redesigning the classic Flasher pattern. This type of origami structure has structural stability that maintains a certain shape range, a high folding and unfolding ratio and a low storage volume ratio, and can achieve the reconfigurability of generated motion. By utilizing its single-degree-of-freedom motion characteristics, the motion control of the entire structure can be achieved by driving a single component during the motion process. Simple physical drive is used for control, which enhances the precise motion control capability of the origami structure and does not destroy the single degree of freedom of the Flasher pattern origami itself. The origami part, by utilizing the high folding rate of the Flasher pattern origami, can achieve folding and unfolding of the target environment, further solving the problem that the rigid lamp cannot adapt to different environments.

[0038] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
