[0002] As a common indoor lighting device, floor lamps are widely used in homes, offices and commercial places. They not only have basic lighting functions, but also have the functions of decoration and atmosphere creation.

In addition, the base of an ordinary floor lamp only serves as a supporting structure and does not have auxiliary lighting or light guidance functions, which cannot meet the needs of modern homes for multi-functional lighting. Therefore, an innovative base design is needed that can not only improve the overall stability but also achieve a uniform and soft base light guidance effect. Summary of the invention

[0021] As a common indoor lighting device, floor lamps are widely used in homes, offices and commercial places. They not only have basic lighting functions, but also have the functions of decoration and atmosphere creation. Its technological development has experienced an evolution from traditional lighting to modern LED (light-emitting diode) lighting. Traditional floor lamps mainly use metal counterweight chassis or wide round bases to maintain stability. The lighting method relies on a single light source in the top lampshade, and the basic lighting function is achieved through simple diffuse reflection. Although this type of design is simple and reliable in structure, it generally has problems such as uneven light distribution and obvious glare, and the base is only a supporting structure and lacks additional functions. With the popularization of LED (light-emitting diode) technology, modern floor lamps have made significant progress in structural design and optical performance. The current mainstream products adopt modular design, which improves stability through stepped support structure and optimized mechanical distribution, while reducing overall weight. In the design of floor lamps, the stability of the base directly affects the safety and user experience of the product. Traditional floor lamp bases usually use simple counterweight structures or wide flat designs to improve stability, but this method often leads to bulky bases, inconvenient transportation, and lack of aesthetics. The current connection between the base of a floor lamp and the lamp body is rather rigid and inflexible, lacking a sense of three-dimensionality and hierarchy. The assembly is rather cumbersome, resulting in a poor user experience. The lamp base is relatively small, the counterweight is relatively light, and it is not stable and sturdy enough. In addition, the base of an ordinary floor lamp only serves as a supporting structure, without auxiliary lighting or light guidance functions, and cannot meet the needs of modern homes for multifunctional lighting. The present application can enhance the user's sense of touch, simplify the assembly steps, and facilitate quick assembly by the user; the sense of hierarchy and three-dimensionality of the lamp body and the base is created through a three-stage stepped structure, and the main body of the base is assembled with the outer cover using a three-stage stepped structure to ensure that the main body of the base has better strength and rigidity, and optimize the structural design of the internal connectors to make the internal connection stronger and more reliable.

[0022] See also Figure 1 to Figure 6 In order to solve the above problems, the present application provides a floor lamp 10, including a bottom plate 20, a base body 30, an upper cover 41, a lamp board 50 and a light guide plate 60. The bottom plate 20 is fixed to the bottom of the base body 30. The base body 30 forms a second step surface 32 and a third step surface 33 on the outer peripheral wall. The third step surface 33 is located below the second step surface 32. The lamp board 50 and the light guide plate 60 are fixed on the second step surface 32. The light guide plate 60 is located below the lamp board 50. The light guide plate 60 is opposite to the third step surface 33 in the height direction and forms a spaced light emitting gap 70. The lamp board 50 is used to emit a light beam to the light guide plate 60. The upper cover 41 is fixed to the base body 30 and covers the peripheral side of the light guide plate 60. The light emitting gap 70 is exposed between the upper cover 41 and the base body 30.

[0023] See also Figure 1 to Figure 6The floor lamp 10 includes a bottom plate 20, a base body 30, an upper cover 41, a lamp board 50 and a light guide plate 60. The bottom plate 20 is located at the bottom of the entire floor lamp 10 and can be fixed to the bottom of the base body 30 by fasteners or snap-on structures to provide a stable basic support, prevent the lamp from tipping over, and enhance the balance of the overall structure. When the floor lamp 10 is placed on the ground, the bottom plate 20 can directly contact the ground. When the floor lamp 10 needs to be placed in other positions, the bottom plate 20 can also be placed in the corresponding position accordingly. The floor lamp 10 can be slid by installing a pulley under the bottom plate 20. The base body 30 is the core bearing structure of the floor lamp 10, and its outer wall adopts a stepped design. The base body 30 forms a second step surface 32 and a third step surface 33. Among them, the third step surface 33 is located below the second step surface 32, and the two together constitute a clearly layered optical and mechanical support structure, which can lower the center of gravity of the base body 30 and improve the stability of the floor lamp 10.

[0024] The upper cover 41 of the floor lamp 10 covers the top of the base body 30, and extends downward to wrap around the side of the light guide plate 60, which plays a protective and shading role. The upper cover 41, the base body 30 and the bottom plate 20 are closely connected to each other, which is solid and reliable. At the same time, the gap between the upper cover 41 and the base body 30 just exposes the light gap 70, ensuring that the light can be evenly sprinkled on the surrounding environment to create an atmosphere lighting effect. The light board 50 is fixed on the second step surface 32, and its surface is integrated with LED (light emitting diode) lamp beads 51, which are used as the main light source to emit light downward. The light guide plate 60 is also installed on the second step surface 32 and is located directly below the light board 50 to receive the light beam emitted by the light board 50. When the upper cover 41 is installed, the light guide plate 60 is arranged in the upper cover 41. The light guide plate 60 is hidden, and the light guide plate 60 will not be directly seen on the appearance of the floor lamp 10, thereby creating a non-glaring light effect. The light guide plate 60 can be made of silicone material, and the semi-hidden lower light emitting surface is in the form of a semi-hidden lower light emitting surface, which avoids the eyes from looking directly at the light emitting part and creates a soft light atmosphere. The light guide plate 60 is provided with a circle of steps to be flush with the light guide lamp board 50, and the light guide lamp board 50 and the light guide plate 60 are fixed and clamped by 4 screws. In addition, the light guide plate 60 can adopt a special optical structure, such as a dot or prism texture, to make the light diffuse evenly. A certain vertical spacing is retained between the light guide plate 60 and the third step surface 33 to form a light emitting gap 70 surrounding the base, so that the light is transmitted outward in a soft and diffuse manner to avoid dazzling glare. When the user uses the floor lamp 10 at night or in a darker scene, the light formed by the lamp board 50 and the light guide plate 60 through the light emitting gap 70 can not only provide an atmosphere light, but also provide guidance for the user to remind the user of the position of the base body 30, which can avoid bumps caused by not being able to see the base position clearly, and improve the user's experience.

[0025] Specifically, in one embodiment, the second step surface 32 adopts an annular platform structure to provide a precise installation reference surface for the lamp board 50 and the light guide plate 60. The third step surface 33 is located 30 to 50 mm below the second step surface 32. The third step surface 33 is an inclined surface. The side of the third step surface 33 close to the second step surface 32 can adopt a gradually tapered inclined surface design, and the height of the third step surface 33 gradually decreases along the radial direction. The low inclined surface angle can be 15 to 25 degrees. The inclined surface structure at a specific angle can, on the one hand, serve as a light reflection surface to directional reflect the light overflowing from the light guide plate 60; on the other hand, it can form a visual level transition on the light to enhance the appearance of the floor lamp 10. At the same time, the edge of the step surface adopts a micro-arc transition treatment, which not only avoids the safety hazards caused by sharp edges, but also improves the diffuse reflection effect of light. The third step surface 33 can usually adopt a PC (polycarbonate) composite material with high reflectivity, and nano-level reflective particles are added to the inner layer to ensure efficient use of light.

[0026] In some embodiments, the second step surface 32 and the third step surface 33 may be connected by structural ribs, which are evenly distributed radially, ensuring structural rigidity and forming a natural airflow channel. A waterproof groove structure is designed on the inner side of the second step surface 32 to prevent condensed water from affecting electrical components. A water guide groove is provided at the bottom edge of the third step surface 33 to quickly guide accidentally spilled liquid, which is beneficial to the maintenance of the floor lamp 10.

[0027] See also Figure 3~Figure 6 The second step surface 32 and the light guide plate 60 are both annular structures, and a clamping platform 61 is formed on the inner ring wall of the light guide plate 60. The light guide plate 60 is overlapped on the second step surface 32 through the clamping platform 61, which can achieve accurate positioning of the light guide plate 60. For example, the light guide plate 60 and the light board 50 can be made into a circular ring shape. The light guide plate 60 can be set to a silicone material, and the surface can be made into a sun-textured matte effect, so that the reflection effect is uniform and there is no black shadow.

[0028] The minimum diameter of the card platform 61 is smaller than the maximum diameter of the second step surface 32. When installed, the light guide plate 60 is naturally buckled on the second step surface 32 through the card platform 61 of its inner ring wall to achieve automatic centering and firm fixation. This overlapping method does not require additional fasteners, which simplifies the assembly process and ensures the position accuracy of the optical components. The contact surface of the card platform 61 adopts a micro-bevel design to avoid stress concentration while ensuring a close fit. The annular matching structure of the light guide plate 60 and the second step surface 32 enables the light to be evenly transmitted 360 degrees. In some embodiments, the light guide plate 60 is fixed to the second step surface 32 to form a reliable optical platform. The light guide plate 60 can be made of optical grade materials, and the surface of the light guide plate 60 is specially textured to efficiently transmit and evenly diffuse light. The lamp board 50 is provided with lamp beads 51, and the lamp beads 51 are distributed in an array on the lamp board 50 to ensure uniform and stable light emission. The lamp beads 51 face the light guide plate 60 in the height direction, and each lamp bead 51 is precisely aligned with the light incident surface of the light guide plate 60 to form a corresponding light path relationship, so that the light emitted by the LED (light emitting diode) can enter the light guide plate 60 at the best angle, thereby maximizing the utilization rate of light energy.

[0029] In some embodiments, the light guide plate 60 may be designed with a double-layer light guide plate 60 stacked. Specifically, the upper layer is a scattering light guide plate 60 responsible for the main lighting, and the lower layer is an atmosphere light guide plate 60 to achieve auxiliary light effects. A light-transmitting isolation layer may be provided between the two layers of light guide plates 60, and dynamic switching of light effects may be achieved through independently controlled LED (light-emitting diode) light groups. In some embodiments, the light guide plate 60 may be divided into multiple independent optical areas, each area corresponding to an independent LED (light-emitting diode) light group. Advanced lighting functions such as local dimming and dynamic light effects may be achieved through an intelligent control system.

[0030] In some embodiments, the light board 50 and the light guide plate 60 may be provided with a hinged connection structure, so that the angle between the light board 50 and the light guide plate 60 is adjustable, and the user may change the incident angle of the light as needed to obtain different lighting effects. For example, a micro damping hinge may be used to connect the light board 50 and the light guide plate 60, the hinge axis is located at the upper edge of the joint between the two, the light board 50 may be adjusted in an axial direction by 15° to 75°, and the light guide plate 60 remains in a horizontal fixed state.

[0031] See also Figure 1 to Figure 6The outer peripheral wall of the base body 30 above the second step surface 32 is a cylindrical surface 34, and the radial dimension of the cylindrical surface 34 is smaller than the second step surface 32. The inner diameter of the lamp panel 50 matches the outer diameter of the cylindrical surface 34. When the lamp panel 50 is installed in place, its inner edge forms a seamless connection with the outer wall of the cylindrical surface 34, which not only ensures the stability of the assembly, but also creates a beautiful visual effect. The inner diameter of the lamp panel 50 matches the outer diameter of the cylindrical surface 34 and can also effectively prevent the lamp panel 50 from being displaced or loosened during long-term use, thereby ensuring the stability of the optical effect of the floor lamp 10. In some embodiments, the surface treatment of the cylindrical surface 34 can adopt a special frosting process, which not only maintains the metal texture but also provides friction, so that the lamp panel 50 can slide in smoothly and be firmly positioned when installed. At the transition between the cylindrical surface 34 and the second step surface 32, a chamfering process can be added, which not only avoids sharp edges, but also strengthens the streamlined beauty of the overall appearance, thereby improving the aesthetics of the appearance of the floor lamp 10.

[0032] The top of the base body 30 forms a first step surface 31, and the upper cover 41 overlaps the first step surface 31 and is sleeved on the cylindrical surface 34. Specifically, the upper cover 41 can be fixed on the first step surface 31 of the base body 30 by 4 screws to form a stable support, which can ensure the precise alignment of the assembly. During installation, when the upper cover 41 is installed in place, the inner wall of the upper cover 41 and the cylindrical surface 34 of the base body 30 can form a stable sleeve relationship. The sleeve relationship between the upper cover 41 and the cylindrical surface 34 can ensure the precise alignment between the upper cover 41 and the base body 30, effectively avoid assembly deviations, and enhance the stability of the overall structure to prevent the upper cover 41 from shaking during use. At the same time, the above-mentioned assembly method is convenient for daily disassembly and maintenance, which is convenient for users to maintain the floor lamp 10 on a daily basis.

[0033] A heat dissipation space is reserved between the upper cover 41 and the base body 30 to form a surround ventilation area, providing continuous and effective heat dissipation protection for internal components. The side of the lamp board 50 facing away from the light guide plate 60 faces the heat dissipation space, so that the heat generated by the LED lamp beads 51 during operation can be directly conducted to the open heat dissipation area to avoid heat accumulation in a confined space. In some embodiments, the heat dissipation space takes into account the physical properties of air convection, with an air inlet at the bottom and an air outlet at the top to form a natural air flow path. The inner wall of the heat dissipation space adopts a heat dissipation fin structure, and the evenly arranged fin structure greatly increases the heat dissipation surface area. At the same time, the reasonable gap retained inside the space ensures that the air can circulate freely without forming hot air stagnation. The high-temperature area on the back of the lamp board 50 is opposite to the widest part of the heat dissipation space, so that the heat can be quickly dispersed to the surrounding environment.

[0034] The floor lamp 10 also includes a connector 80 and a lamp tube 90. A through hole 35 is provided at the top of the base body 30. The lamp tube 90 and the connector 80 are fixed in the through hole 35. The lamp tube 90 is the main light-emitting element of the floor lamp 10 and can provide an atmosphere light. The bottom of the lamp tube 90 is firmly fixed inside the through hole 35 through the connector 80. The connector 80 is made of high-strength material and has a hollow columnar structure. It is cleverly embedded in the internal space of the lamp tube 90 to provide a stable support from the inside, effectively preventing the lamp tube 90 from shaking or shifting during use. The connector 80 is located inside the lamp tube 90 to support the lamp tube 90. In one embodiment, the lamp tube 90 is assembled with the base body 30, and the connector 80 is fixed to the base body 30 by two symmetrical screws. In some embodiments, the outer surface of the connector 80 is provided with anti-rotation lines to ensure that no circumferential displacement occurs after installation; at the same time, its bottom is provided with an elastic buckle structure, which can be firmly fixed by simply pressing, which is convenient for installation and ensures stability. The interface between the lamp tube 90 and the connector 80 uses a soft cushioning material to ensure a close fit and avoid damage caused by hard contact. In some embodiments, the inner wall of the through hole 35 is specially treated and provided with a waterproof and dustproof sealing ring to protect the internal electrical connection from environmental influences. A wiring channel is reserved inside the connector 80 so that the power cord can pass through it in a hidden and orderly manner. In some embodiments, the outer peripheral wall of the base body 30 forms a plurality of ribs 331 below the third step surface 33, and the ribs 331 extend in the height direction, and the plurality of ribs 331 are evenly spaced and arranged around the base circumferentially. The ribs 331 gradually narrow from the bottom to the top, which can ensure the support strength of the lower part of the base. The spacing between adjacent ribs 331 can ensure structural rigidity while maintaining good air circulation.

[0035] The floor lamp 10 further includes a decorative cover 42, which is sleeved on the base body 30 and covers the ribs 331. When the decorative cover 42 is installed in place, the ribs 331 are hidden, which can improve the stability of the floor lamp 10 on the basis of increasing the stability of the base of the floor lamp 10. The light-emitting gap 70 is located between the upper cover 41 and the decorative cover 42, ensuring that the light can overflow evenly and softly, which is neither too glaring nor too bright. When used at night, this light strip will emit ambient light, which can not only provide an indication function but also create a warm atmosphere. The wall thickness of the decorative cover 42 can be set to 2.5 to 3.0 mm to ensure sufficient strength and rigidity. In some embodiments, the decorative cover 42 is provided with 4 buckles, and the third step surface 33 of the base bracket is provided with 4 slots, and the buckles correspond to the slots one by one to realize the assembly of the decorative cover 42. In some embodiments, the decorative cover 42 is also provided with a square notch for avoidance, which can serve as an assembly alignment mark.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
