[0002] Lamps are a general term for lighting tools, including table lamps, chandeliers, wall lamps, floor lamps, etc. During the use of various lamps, in order to adjust their lighting range, light intensity, etc., they are often used in conjunction with lamp shades. Currently, for most lamps, the lamp shade is fixedly arranged relative to the light source, and the light shielding range cannot be adjusted.

[0028] The features and exemplary embodiments of various aspects of the present application will be described in detail below. To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than limiting the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0029] It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0030] Lamps are often used together with lamp shades, and the lighting range, light intensity, etc. of the light source can be controlled through the lamp shade. Most lamp shades are fixedly arranged relative to the light source and cannot be adjusted in shape, and there are also some lamp shades that can change their shape through a mechanical transmission mechanism. However, when changing the shape of the lamp shade through mechanical transmission, there are problems such as a complex transmission mechanism and easy failure.

[0031] To solve the problems of the prior art, the embodiments of the present application provide an adjusting piece and a table lamp based on a shape memory metal. First, the adjusting piece 5 provided by the embodiments of the present application will be introduced below.

[0032] Please refer to Figure 1 , Figure 1 which shows a schematic exploded view of the adjusting piece 5 provided by some embodiments of the present application.

[0033] The embodiments of the present application provide an adjusting piece 5, as Figure 1As shown in the figure, the adjusting piece 5 includes a shielding layer, a restraint member 3, a shape memory metal member 1, and a heat exchange member 2. Among them, the shielding layer has a first form and a second form with different shapes; the restraint member 3 is installed on the shielding layer and conforms to the contour of the shielding layer; the shape memory metal member 1 is installed on the shielding layer and fits within the area surrounded by the restraint member 3. The shape memory metal member 1 deforms with temperature changes and can drive the shielding layer to transform at least between the first form and the second form together with the restraint member 3; the heat exchange member 2 is installed on the shielding layer and is connected to the shape memory metal member 1.

[0034] The shielding layer, as the main body of the adjusting piece 5, can carry the restraint member 3, the shape memory metal member 1, and the heat exchange member 2. The shielding layer is soft and deformable. For example, it can be used for shading, wind blocking, etc., and serves as a barrier between media. For example, when shading, the shielding layer has different light shielding areas in different forms, so the light range of the light source can be adjusted. The shielding layer can be a material without a specific form by itself. For example, it can be a cloth piece of a cloth-based material. The shielding layer can also be a soft and deformable material. For example, it can be a soft polymer material sheet (such as a soft plastic sheet), or it can be a paper sheet.

[0035] The restraint member 3 is installed on the shielding layer and conforms to the contour of the shielding layer. As the framework of the shielding layer, it can shape the shielding layer. The restraint member 3 can select a material that can undergo elastic deformation, such as a metal wire, which maintains its preset shape (maintaining the shielding layer in the first form) under the condition of no external force; it can deform with the external force under the action of an external force (the shielding layer gradually transforms towards the second form); after the external force is removed, it restores to the preset shape by relying on the elastic restoring force (maintaining the shielding layer in the first form).

[0036] The shape memory metal member 1 is installed on the shielding layer and serves as the power source for the shape change of the shielding layer, enabling the shielding layer to gradually transform from the first form to the second form. The shape memory metal member 1 cooperates with the restraint member 3 to drive the shielding layer to transform at least between the first form and the second form, which means that when the shape memory metal member 1 deforms, it can do work against the binding force of the restraint member 3 to drive the shielding layer to transform from the first form to the second form, or the restraint member 3 can do work against the acting force of the shape memory metal member 1 to drive the shielding layer to transform from the second form to the first form.

[0037] The shape memory metal member 1 can adopt an alloy material with a shape memory effect. It is soft under normal conditions and deforms under the action of the restraint member 3 and the shielding layer, making the shielding layer in the first form. When the temperature changes, the shape memory metal member 1 undergoes a phase change and hardens, overcoming the binding force of the restraint member 3, and can cause the shielding layer to gradually transform towards the second form.

[0038] The heat exchange member 2 is installed on the shielding layer and connected to the shape memory metal member 1, which can provide temperature change support for the phase change of the shape memory metal member 1. By controlling the change of the shape memory metal member 1 through temperature change, the shielding layer can be transformed between at least a first form and a second form.

[0039] The adjusting piece 5 can be used individually. When used individually, it can be used as a light shielding barrier and placed between the user and the light source. The shape of the adjusting piece 5 changes slowly over time, and thus the light transmittance changes slowly. The adjusting pieces 5 can also be used simultaneously in multiple numbers. When used simultaneously in multiple numbers, they can surround the outer periphery of the light source to form a lampshade. When the adjusting pieces 5 change slowly, the light shielding range changes gradually.

[0040] In addition to being used for adjusting light, the adjusting piece 5 can have various other uses. For example, the adjusting piece 5 can be designed in the shape of a petal. Multiple adjusting pieces 5 cooperate with each other to simulate the slow opening and closing of a flower, and a handicraft for knowledge popularization can be made; the adjusting piece 5 can be used in painting to make a dynamic painting in which painting elements (such as butterflies and flowers) can change slowly; the adjusting piece 5 can also be used as a wind deflector to adjust the air volume when changing between the first form and the second form, and is suitable for an air conditioner air outlet, etc.

[0041] The adjusting piece 5 provided in the embodiment of the present application includes a shielding layer and a constraint member 3, a shape memory metal member 1, and a heat exchange member 2 installed on the shielding layer. The heat exchange member 2 provides a temperature change for the shape memory metal member 1, enabling the shape memory metal member 1 to undergo a phase change, overcoming the binding force of the constraint member 3 to cause the shielding layer to transform from the first form to the second form, or the shape memory metal member 1 undergoes a phase change, and the constraint member 3 overcomes the acting force of the shape memory metal member 1 to cause the shielding layer to transform from the second form to the first form. When the shielding layer changes its form, it does not require the participation of a mechanical transmission mechanism. Only by relying on the inherent characteristics of the shape memory metal member 1 and adjusting the interaction force between the constraint member 3 and the shape memory metal member 1 can the transformation between the first form and the second form be achieved. The structure is simple and not easily fails. In addition, the shielding layer relies on the characteristics of the shape memory metal member 1 to change its form, and has the characteristic of a slow change process during the form change, without sudden change, and the use experience is more comfortable.

[0042] In some embodiments, as Figure 1 shown, the shape memory metal member 1 is arranged in a serpentine shape on the shielding layer. The shape memory metal member 1 includes a plurality of parallel extending segments, and the deformation direction of the extending segments is perpendicular to the surface of the shielding layer.

[0043] The shape memory metal member 1 includes a plurality of extending segments, and the plurality of extending segments are arranged in parallel, which can form a tiled effect on the shielding layer. The deformation direction of the extending segments is perpendicular to the surface of the shielding layer. Therefore, when the shielding layer transforms between the first form and the second form, the form change occurs perpendicular to the surface of the shielding layer. For example, when the shielding layer is used to shield a light source, it can bend towards the light source or away from the light source.

[0044] There are multiple extension sections, and when the memory metal part 1 applies a force, the force on the shielding layer can be more dispersed. Compared with other arrangements, the pressure on the shielding layer can be reduced under the premise that the force remains unchanged, thereby preventing the shielding layer from being crushed. When the shielding layer changes its form, the shape changes perpendicular to its own surface, and there is no situation where surface folds or wrinkles are formed that affect the service life of the shielding layer. In addition, when the shielding layer changes its form, it can form a contraction (which can be the first form) and expansion effect (which can be the second form) relative to the light source. When contracted, it is close to the light source and the shading effect is strong. When expanded, it is far from the light source and the shading effect is weak, thereby forming a slow change in light intensity.

[0045] In some embodiments, as Figure 1 As shown, the memory metal piece 1 is a one-way memory alloy wire, which is easier to obtain, cheaper, does not require a complicated training process, and can reduce manufacturing difficulty and manufacturing cost.

[0046] The one-way memory alloy wire can be a shape memory alloy wire with a diameter of 1.5 mm. The one-way memory alloy wire can be manufactured using digital manufacturing technology (such as automatic textile technology, 3D printing technology, etc.). When the memory metal part 1 is connected to the shielding layer, it can be woven on the shielding layer using a household sewing and embroidery machine to form a tightly arranged serpentine line on the shielding layer. The straight section of the serpentine line is an extension section, and adjacent extension sections are connected at the end. In other feasible forms, the memory alloy wire can also have multiple unconnected sections, and each section woven into the shielding layer forms an extension section.

[0047] like Figure 2 As shown, the one-way memory alloy wire can maintain its current state under the action of the constraint member 3 and the shielding layer at room temperature, and the shielding layer is maintained in the first form. Figure 3 As shown, the one-way memory alloy wire can be hardened after being heated, overcome the bending stress of the constraint member 3 to do work, and drive the shielding layer to slowly transform toward the second shape until it maintains the second shape.

[0048] In some embodiments, as Figure 1 As shown, the heat exchange element 2 is a heating wire laid in a serpentine pattern on a shielding layer to form a heating layer. Along the extension direction of the extended section, the heating layer includes a first heating zone 21 and a second heating zone 23. In the first heating zone 21, the length of the heating wire is perpendicular to the extension; in the second heating zone 23, the length of the heating wire is parallel to the extension.

[0049] The heat exchange member 2 is a heating wire, which is laid tightly in a serpentine shape on the shielding layer, and can form a heating layer that fits the surface of the shape memory metal member 1, directly heating the shape memory metal member 1 to provide the temperature required for the phase change of the shape memory metal member 1. Exemplarily, the heating layer can use an enameled conductive wire (heating wire) with a diameter of 1.8 mm and is woven on the shielding layer by a household sewing and embroidery integrated machine.

[0050] In the first heating zone 21, the length direction of the heating wire refers to the direction along the straight section when the heating wire is arranged in a serpentine shape; in the second heating zone 23, the length direction of the heating wire refers to the direction along the straight section when the heating wire is arranged in a serpentine shape.

[0051] The length direction of the heating wire in the first heating zone 21 is perpendicular to the extension section, and it will not hinder the deformation when the extension section deforms. Therefore, the part of the shielding layer in the first heating zone 21 is easier to deform; the length direction of the heating wire in the second heating zone 23 is parallel to the extension section, and the heating wire can play a certain supporting role for the extension section. Therefore, the deformation amplitude of the part of the shielding layer in the second heating zone 23 is reduced under the same conditions. The differential setting of the routing form of the heating wire in the first heating zone 21 and the second heating zone 23 can regulate the deformation amplitude of different regions of the shielding layer.

[0052] Exemplarily, one end of the adjusting piece in the first heating zone 21 can be used as a connection end and is relatively fixed to the light source, and one end of the adjusting piece in the second heating zone 23 can be used as a free end. When the adjusting piece transforms between the first form and the second form, the overall spatial position is more likely to change, while the local form change in the second heating zone 23 is smaller. Therefore, the controllability of the deformation of the adjusting piece is stronger.

[0053] In some embodiments, as Figure 1 shown, along the extension direction of the extension section, the first heating zone 21 is provided with a first overlapping portion, and the second heating zone 23 is provided with a second overlapping portion; the first overlapping portion and the second overlapping portion overlap to form an overlapping zone 22.

[0054] In the overlapping zone 22, it can be that the first overlapping portion covers the upper layer of the second overlapping portion, or the second overlapping portion covers the upper layer of the first overlapping portion. In the overlapping zone 22, the heating wires are criss-crossed, which can keep the part of the shielding layer in the overlapping zone 22 in a fixed shape and prevent deformation.

[0055] In some embodiments, as Figure 1 shown, the restraining member 3 includes a restraining wire 32 and an elastic skeleton 31; the restraining wire 32 is arranged on the shielding layer, and a plurality of restraining rings are provided along the contour of the shielding layer, and the plurality of restraining rings are arranged at intervals; the elastic skeleton 31 is inserted into the restraining rings and can elastically deform to support the shielding layer.

[0056] The restraint wire 32 can be woven on the shielding layer along the outer contour of the shielding layer. When the restraint wire 32 extends along the outer contour of the shielding layer, it can include a plurality of alternately arranged inner segments and outer segments. The restraint wire 32 is not woven on the shielding layer between adjacent inner segments and outer ends, thereby forming a series of flat restraint loops for the elastic framework 31 to pass through.

[0057] The restraint wire 32 can be an enameled conductive wire with a diameter of 1.8 mm. The material selection is the same as that of the heating wire, which can reduce the types of materials and improve interchangeability. In other feasible implementation schemes, the restraint wire 32 can also adopt other hard silk wires.

[0058] The elastic framework 31 can be made of 304 stainless steel elastic wire with a diameter of 0.1 mm. The elastic framework 31 is bent into a predetermined shape that can maintain the adjusting piece 5 in the first form. When the heat exchange member 2 heats the shape memory metal member 1, the shape memory metal member 1 can do work against the acting force of the elastic framework 31 and drive the adjusting piece 5 to transform towards the second form.

[0059] The elastic framework 31 is inserted through a plurality of restraint loops along the outer contour of the shielding layer and is connected to the shielding layer through the restraint loops, rather than directly connected to the shielding layer, and even less connected to the shielding layer at every point in the extending direction. This can avoid the formation of local stress concentration areas between the shielding layer and the elastic framework 31, thereby protecting the shielding layer from being damaged.

[0060] In some embodiments, as Figure 1 shown, the shielding layer includes a connected first shielding layer and a second shielding layer, and a sandwich layer is formed between the first shielding layer and the second shielding layer; the restraint member 3, the shape memory metal member 1, and the heat exchange member 2 are all located in the sandwich layer.

[0061] The first shielding layer and the second shielding layer can be combined into one body in the form of sewing at the outer contour. When sewing, the sewing thread can adopt a V shape to form a plurality of sawteeth, improving the connection strength. In other feasible implementation schemes, the first shielding layer and the second shielding layer can also be combined into one body in the form of adhesive connection at the outer contour.

[0062] The restraint member 3, the shape memory metal member 1, and the heat exchange member 2 are all located in the sandwich layer formed by the first shielding layer and the second shielding layer, and thus can protect the restraint member 3, the shape memory metal member 1, and the heat exchange member 2, reducing the interference generated by the external environment on the restraint member 3, the shape memory metal member 1, and the heat exchange member 2.

[0063] In some embodiments, the first shielding layer and / or the second shielding layer is impregnated with a thermochromic material that can change color when the temperature changes.

[0064] Exemplarily, a coating formed of a temperature-sensitive color-changing material may be provided on the first shielding layer, or a coating formed of a temperature-sensitive color-changing material may be provided on the second shielding layer, or coatings formed of a temperature-sensitive color-changing material may be provided on both the first shielding layer and the second shielding layer simultaneously. When forming the coating, the temperature-sensitive color-changing material may be attached to the first shielding layer and / or the second shielding layer by means of dyeing. The temperature-sensitive color-changing material may be prepared by dissolving a 40°C colorless-to-colored magenta powder in an acrylic paint blending liquid and mixing it with water in a ratio of 1:0.5 to 1:1.

[0065] The shielding layer is dyed with a temperature-sensitive color-changing material, so that the shielding layer can change color when the heat exchange member 2 is heated, and thus the heat exchange member 2 can drive the adjusting piece 5 (shielding layer) to deform and change color simultaneously. After the shielding layer is heated, its color changes from light to dark. Combining with its own morphological change (changing from the first form to the second form), it can enrich the adjustable elements of the adjusting piece 5 and make it applicable to various scenarios (such as adjusting light, simulating flowers, dynamic painting, etc.). For example, when the adjusting piece 5 adjusts the light, the shielding layer is close to the light source when in the first form and far from the light source when in the second form. When the light source is just turned on, the light intensity and the light range can be reduced, and the boundary between the light-shielding area and the illuminated area is not obvious; then the light intensity in a specific range gradually increases, forming a light-shielding area and an illuminated area with a clear boundary, which can make the audience more comfortable during lighting adjustment.

[0066] Please refer to Figures 2 to 5 , Figure 2 which is a schematic structural diagram of the table lamp based on shape memory metal provided by some embodiments of the present application when the adjusting piece is in the first form; Figure 3 which is a schematic structural diagram of the table lamp based on shape memory metal provided by some embodiments of the present application when the adjusting piece is in the second form; Figure 4 which is a cross-sectional view of the open container provided by some embodiments of the present application; Figure 5 which is a schematic connection diagram of the mounting bracket and the adjusting piece provided by some embodiments of the present application.

[0067] As Figure 2 shown, some embodiments of the present application further provide a table lamp based on shape memory metal, including a lamp base, a light-emitting unit, and an adjusting piece 5; the light-emitting unit and the adjusting piece 5 are both mounted on the lamp base, and there are multiple adjusting pieces 5 surrounding the outside of the light-emitting unit.

[0068] The lamp base is the installation foundation and can provide installation positions for the light-emitting unit and the adjusting piece 5. The light-emitting unit may be an LED lamp, or may also be an incandescent lamp, a fluorescent lamp, or a halogen lamp. After the light-emitting unit is powered on, it becomes a light source for emitting light and providing illumination.

[0069] As Figure 2 shown, multiple adjusting pieces 5 surround the outside of the light-emitting unit to form an adjustable lampshade. The adjusting piece 5 is close to the light-emitting unit when in the first form. AsFigure 3 As shown, when the adjusting piece 5 is in the second form, it is far from the light-emitting unit, and gradually moves away from the light-emitting unit when changing from the first form to the second form.

[0070] The table lamp based on shape memory metal provided by the embodiments of the present application includes a lamp base, a light-emitting unit, and adjusting pieces 5. A plurality of adjusting pieces 5 surround the outside of the light-emitting unit to form a lampshade. When powered on, the light-emitting unit is lit, the heat exchange member 2 heats the shape memory metal member 1, and the plurality of adjusting pieces 5 can slowly unfold like blooming flowers, thereby slowly adjusting the light of the light-emitting unit, which conforms to the adaptation habit of the human eye and is more comfortable to use.

[0071] In some embodiments, as Figure 2 and Figure 5 shown, the lamp base includes a mounting bracket 6, and the mounting bracket 6 includes a supporting portion 61 and a rod portion 62; the supporting portion 61 includes a lamp housing 4 and a supporting piece, the light-emitting unit is installed in the lamp housing 4, and the adjusting piece 5 is installed on the supporting piece; the rod portion 62 is hollow and communicates with the lamp housing 4 and the supporting piece.

[0072] The whole mounting bracket 6 is rod-shaped, and a supporting portion 61 for installing the light-emitting unit and the adjusting piece 5 is provided at one end. The rod portion 62 is a circular tube, which can be a metal tube, a glass tube, a plastic tube, etc. The bottom of the lamp housing 4 communicates with the hollow cavity of the rod portion 62, and a hole communicating with the hollow cavity of the rod portion 62 is also processed at the supporting piece. There are a plurality of supporting pieces, which protrude obliquely upward along the outer peripheral surface of the supporting portion 61 and surround the circumference outside the lamp housing 4. The number of the supporting pieces corresponds to the number of the adjusting pieces 5 one by one, and can provide an installation position for the installation of the adjusting piece 5. As an implementable solution, the mounting bracket 6 is integrally provided, that is, the supporting portion 61 and the rod portion 62 can be integrally formed, or can be combined into one after being formed separately.

[0073] The light-emitting unit is installed in the lamp housing 4. The lamp housing 4 can provide protection for the light-emitting unit to prevent the light-emitting unit from being bumped, and can adjust the brightness of the light-emitting unit to a certain extent (for example, the lamp housing 4 can be set in a semi-transparent form). The adjusting piece 5 can be bonded to the supporting piece, abuts against the supporting piece, and is located between the lamp housing 4 and the supporting piece. The light-emitting unit and the adjusting piece 5 need external power supply support during operation. The connecting wire of the light-emitting unit can penetrate into the hollow cavity of the rod portion 62 from the bottom of the lamp housing 4, and the connecting wire of the adjusting piece 5 can penetrate into the hollow cavity of the rod portion 62 through the hole communicating with the hollow cavity of the rod portion 62 at the supporting piece. By arranging the circuits of the light-emitting unit and the adjusting piece 5 through the hollow cavity of the rod portion 62, the exposure of the circuits can be avoided, and the safety during use can be improved.

[0074] In some embodiments, as Figure 3 and Figure 4As shown, the lamp socket further includes an open container 7. The open container 7 includes a wall portion 71 and a receiving cavity. A partition plate 711 is provided in the receiving cavity, and an opening 7111 is provided on the partition plate 711; the rod portion 62 is inserted into the opening 7111 and is in sealing fit with the opening 7111 or formed integrally therewith.

[0075] The partition plate 711 divides the space in the receiving cavity into two parts, and the partition plate 711 is arranged parallel to the bottom surface of the open container 7. In the receiving cavity, the space above the partition plate 711 is larger than the space below the partition plate 711. The space above the partition plate 711 can be used for storing items, and the space below the partition plate 711 can be used as a placement space for the circuit. The rod portion 62 is inserted into the opening 7111. On the one hand, it can provide a fixed position for the rod portion 62 to ensure the firm connection between the mounting bracket 6 and the open container 7. On the other hand, it can directly send the circuits of the adjusting piece 5 and the light-emitting unit into the space below the partition plate 711 through the rod portion 62, avoiding the circuits being exposed to the space above the partition plate 711.

[0076] When the rod portion 62 is connected to the opening 7111, sealing fit can be selected. For example, a sealing ring is provided at the opening 7111 to seal the gap between the rod portion 62 and the opening 7111. When the rod portion 62 is connected to the opening 7111, it can also be selected that the rod portion 62 and the opening 7111 are formed integrally. For example, both the rod portion 62 and the open container 7 can be made of glass material, and the rod portion 62 and the opening 7111 are in clearance fit or transition fit and are adhesively sealed and formed integrally; the rod portion 62 and the open container 7 can also be made of polymer material, and the rod portion 62 is heat-melted and connected to the opening of the partition plate 711 to form an integral body.

[0077] A partition plate 711 is provided in the open container 7, and the opening 7111 of the partition plate 711 is sealed, which can isolate the space above the partition plate 711 from the space below it. Therefore, when the space above the partition plate 711 is used for storing items, it can have various uses. For example, it can be used as a vase to store flower bouquets, as a vase to plant green plants (even hydroponic green plants), as an aquarium to place ornamental fish, as a pen holder to place various pens, as a storage box to place sundries, etc.

[0078] In some embodiments, as Figure 3 shown, the open container 7 is provided with a base portion 72, and a central control circuit is provided in the base portion 72. The central control circuit includes a power supply circuit and a voice control circuit; the voice control circuit is electrically connected to the light-emitting unit and the adjusting piece 5, and the power supply circuit is electrically connected to the voice control circuit.

[0079] The base portion 72 can be in the shape of a square platform. The base portion 72 is located at the lower part of the open container 7 and below the partition plate 711. The base portion 72 is hollow and communicates with the space below the partition plate 711. The central control circuit can be placed in it, and the central control circuit can be connected to the light-emitting unit and the adjusting piece 5. Along the longitudinal direction of the open container 7, the outer contour of the base portion 72 is larger than the outer contours of other parts of the open container 7, which can also ensure the stability of the open container 7 when placed.

[0080] The central control circuit includes a power supply circuit and a voice control circuit. The power supply circuit can supply power to the light-emitting unit, the adjusting piece 5, and the voice control circuit. The voice control circuit can receive user voice commands and adjust the control signal to control the deformation, color change, and the switching process of the light-emitting unit of the adjusting piece 5. When connecting the circuits, the connecting wires of the light-emitting unit and the connecting wires of the adjusting piece 5 both pass through the hollow cavity of the rod portion 62 and are connected to the voice control circuit. After receiving the user voice input, the voice control circuit can control the on-off of the circuits of the light-emitting unit and the adjusting piece 5 and the magnitude of the current, thereby realizing the voice control operation function.

[0081] As Figures 1 to 5 shown, the working process of the desk lamp based on shape memory metal will be described in detail with a specific embodiment below:

[0082] The desk lamp based on shape memory metal includes a lamp base, a light-emitting unit, and a plurality of adjusting pieces 5. The lamp base includes a mounting frame 6 and an open container 7. The mounting frame 6 is rod-shaped, and the open container 7 is a quadrangular prism-shaped tube. The mounting frame 6 includes a supporting portion 61 and a rod portion 62. The supporting portion 61 includes a lamp housing 4 and supporting pieces. The lamp housing 4 is a white semi-transparent plastic shell, and the number of supporting pieces is multiple, for example, 4. The open container 7 includes a wall portion 71, a receiving cavity, and a base portion 72. A partition plate 711 is provided in the receiving cavity, and a central control circuit is provided in the base portion 72. The central control circuit includes a power supply circuit and a voice control circuit. The light-emitting unit uses an LED light strip and is placed in the lamp housing 4. The adjusting piece 5 includes a shielding layer, a constraining member 3, a shape memory metal member 1, and a heat exchange member 2. The shielding layer includes a first shielding layer and a second shielding layer. The second shielding layer is located below the first shielding layer. From the second shielding layer to the first shielding layer are the heat exchange member 2 and the shape memory metal member 1 in sequence, and the constraining member 3 is located outside the shape memory metal member 1. The number of adjusting pieces 5 corresponds to the number of supporting pieces one by one. The shielding layer is a fabric base (such as a cotton cloth base) and is colored with a temperature-sensitive color-changing material. The connecting wires of the light-emitting unit and the connecting wires of the plurality of heat exchange members 2 pass through the hollow rod portion 62 and are connected to the central control circuit. The connecting wires of the plurality of heat exchange members 2 can be connected in series or in parallel.

[0083] During use, the user speaks a command, such as "turn on the light". At this time, the LED light strip and the heat exchanger 2 are energized, the LED light strip is lit, the heat exchanger 2 heats the memory metal part 1, the memory metal part 1 undergoes a phase change and hardens, and the adjustment plate 5 begins to slowly move away from the LED light strip. The multiple adjustment plates 5 change from the first form to the second form and slowly unfold, so that the lighting of the LED light strip can be slowly adjusted. While the heat exchanger 2 heats the memory metal part 1, it also heats the shielding layer. The temperature-sensitive color-changing material on the shielding layer changes color after being heated, for example, the color can gradually become darker. At the moment the light is turned on, the LED light strip is surrounded by multiple adjustment plates 5, and at this time the adjustment plates 5 are light-colored, so the desk lamp can emit light of lower brightness, which is easier for the human eye to adapt. The adjustment plates 5 change slowly over time, gradually unfolding and deepening in color, so that the desk lamp can form a clearly defined shading area and illumination area.

[0084] During use, the user says a command, such as "turn off the lights". At this time, the LED light strip and the heat exchanger 2 are powered off, the LED light strip goes out, the heat exchanger 2 stops heating, the memory metal part 1 undergoes phase change and softens, and the restraint part 3 overcomes the force of the memory metal part 1 and does work, causing the adjustment piece 5 to bend toward the LED light strip, the color of the shielding layer gradually becomes lighter, and multiple adjustment pieces 5 slowly gather around the periphery of the LED light strip.

[0085] Desk lamps are common indoor lighting fixtures, often placed on desks and other areas close to the user to provide a range of illumination. Modern desk lamp design also places great emphasis on aesthetics. Flowers are also common desktop items, making the two a suitable combination. However, some technologies have attempted to combine flowers with desk lamp elements, but have failed to replicate the natural effect of flowers slowly opening and gradually changing color.

[0086] In order to enrich the use and improve the ornamental value, the present application can design the appearance so that the table lamp becomes a flower table lamp that changes color and blooms, and can be used as a vase for flower arrangement.

[0087] Specifically, the open container 7 is designed in the shape of a vase for placing flowers. The mounting frame 6 can be designed in the shape of a flower branch, with the stem 62 shaped like a flower stem, the support 61 shaped like a receptacle, the support piece shaped like a sepal, and the lamp housing 4 shaped like a stigma. The adjustment piece 5 can be designed in the shape of a petal, with the first configuration of the adjustment piece 5 being a curved configuration. The entire area of the adjustment piece 5 is covered with heat exchange elements 2, and the memory metal element 1 extends from the connection end of the petals to the free end.

[0088] When not powered on, when multiple adjusting pieces 5 gather outside the lamp housing 4, the mounting bracket 6 and the multiple adjusting pieces 5 resemble a flower in bud. After being powered on, the LED light strip is lit inside the stigma-shaped lamp housing 4, and the multiple adjusting pieces 5 slowly change towards the second form, and at the same time the color gradually deepens, which can simulate the process of a flower slowly blooming. After power-off, the LED light strip goes out, and the multiple adjusting pieces 5 slowly change towards the first form, gathering around the outer periphery of the lamp housing 4, and as the adjusting pieces 5 slowly deform, the color of the adjusting pieces 5 gradually fades, which can simulate the process of a flower slowly closing.

[0089] As described above, only the specific embodiments of the present application are provided. Those skilled in the art can clearly understand that for the convenience and brevity of description, the specific working processes of the systems, modules, and units described above can refer to the corresponding processes in the foregoing method embodiments, and will not be elaborated herein. It should be understood that the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application.
