Description

Technical Field

[0001] This utility model relates to the field of projection technology, specifically to a projection floor lamp. Background Technology

[0002] Floor lights are low-mounted lighting fixtures installed at the bottom of interior walls, on the ground, or near baseboards. They are mainly used for auxiliary lighting at night, and their light is soft and non-glaring, ensuring the safety of people walking in low-light environments and can also be used for ambiance decoration.

[0003] To expand usage scenarios, many floor lights on the market have added projection functions. These typically achieve light and shadow effects through built-in fixed-pattern projection sheets or films. However, the projected patterns are mostly fixed and cannot be flexibly changed according to usage scenarios or personal preferences. While some floor lights now support pattern switching by manually replacing individual projection sheets, this method is not only cumbersome and unable to achieve quick and convenient scene adaptation, but frequent operation can also shorten product lifespan and negatively impact user experience.

[0021] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the projection foot lamp in the embodiment. Figure 2 This is a schematic diagram of the internal structure of the projection floor lamp in this embodiment. The projection floor lamp in this embodiment includes a housing assembly 1 and a projection assembly 2. The housing assembly 1 has a first projection port 111 and an adjustment port 112 on its surface. The projection assembly 2 includes a light source 21 and a switching component 22. The light source 21 is disposed inside the housing assembly 1. The switching component 22 has multiple pattern areas. The switching component 22 is movably disposed inside the housing assembly 1, and part of the switching component 22 is exposed outside the housing assembly 1 through the adjustment port 112. By moving the switching component 22, the light source 21 is aligned with one of the pattern areas, and the light source of the light source 21 passes through one of the pattern areas and the first projection port 111 and is emitted to the outside to form a projection.

[0023] The projection floor lamp in this embodiment is applicable to various lighting scenarios such as hotels, shops, and homes. Since the switching element 22 has multiple pattern areas, each with a different projection pattern, the light source of the light source 21 passes through different pattern areas and projects different patterns outwards through the first projection port 111. When the user needs to switch the projection pattern, they only need to toggle the switching element 22 so that the light source 21 is aligned with the different pattern area on the switching element 22. In this way, the light source of the light source 21 passes through the pattern area and the first projection port 111 and projects outwards, forming different pattern projections. This allows for pattern replacement to adapt to different application scenarios, while improving convenience and user experience.

[0024] Preferably, multiple pattern areas are arranged around the switching element 22, which is rotatably mounted within the housing assembly 1. In specific applications, the switching element 22 is disc-shaped, with multiple pattern areas arranged circumferentially to form a ring array. When the user rotates the switching element 22, each pattern area moves accordingly and sequentially passes through a projection working position directly opposite the light source 21. When a pattern area rotates to this working position, that is, when the pattern area is directly opposite the light source 21, the light from the light source 21 passes through this pattern area to form a projection, while the other pattern areas surrounding it are in idle positions outside the light path and do not interfere with each other. The ring layout is compact, accommodating more pattern areas within a limited space. Furthermore, the method of rotating the switching element 22 for switching is intuitive and quick, allowing users to accurately locate the target pattern with a simple rotation, achieving convenient pattern switching and improving user experience and convenience.

[0025] Reference Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the switching component in the embodiment. Figure 4The diagram illustrates the structure of the first and second rotating disks in the embodiment. Preferably, the switching component 22 includes a first rotating disk 221, a second rotating disk 222, and a projection sheet 223. The first and second rotating disks 221 and 222 are rotatably disposed within the housing assembly 1, and a clamping space exists between them. The projection sheet 223 is clamped within this clamping space and has multiple patterned areas. The first and second rotating disks 221 and 222 each have multiple patterned holes 2211 corresponding to the patterned areas. In practical applications, the first and second rotating disks 221 and 222 are interlocked and fixed together by a snap-fit ​​structure on their periphery, thereby forming a clamping space between them to accommodate the projection sheet 223 and connecting them into a synchronously rotating whole. The projector 223 is tightly clamped within the clamping space. The projector 223 has multiple patterned areas. The first rotating disk 221 and the second rotating disk 222 each have a patterned hole 2211 corresponding to a patterned area. The user can rotate the entire structure synchronously by turning the exposed first and second rotating disks 221 and aligning the different patterned areas on the projector 223 with the light source 21 in sequence. When a patterned area is aligned with the light source 21, light passes sequentially through the patterned holes 2211 of the first rotating disk 221, the patterned area, and the second rotating disk 222 before being emitted to form a projection. The snap-fit ​​fixing structure between the first rotating disk 221 and the second rotating disk 222 is easy to assemble and reliably connected, providing a stable support for the projector 223 and effectively preventing displacement or deformation during use, ensuring accurate projection alignment and stable imaging. Meanwhile, the integrated design of the first rotating wheel 221 and the second rotating wheel 222 enables high-density integration of a large number of patterns and fast, reliable cyclic switching within a compact space, significantly improving the product's practicality and user experience.

[0026] Reference Figure 5 and Figure 6 , Figure 5 This is another structural schematic diagram of the projection floor lamp in the embodiment. Figure 6The diagram illustrates the structure of the base shell in this embodiment. Preferably, the shell assembly 1 includes a cover 11 and a base shell 12. The cover 11 covers the base shell 12. A first projection port 111 and an adjustment port 112 are respectively formed on the surface of the cover 11. A light source 21 is disposed on the base shell 12, and a switching component 22 is movably disposed on the base shell 12. In practical applications, the cover 11 and the base shell 12 together form the internal cavity of the projection floor lamp. The back of the base shell 12 has an installation structure that matches a standard wall socket box, allowing it to be directly fixed to a universal 86-type box. This eliminates the need for additional wall modifications, adapting to existing building environments. Specifically, the base shell 12 has multiple mounting holes 121. The positions of the mounting holes 121 correspond to the fixing screw holes on the standard 86-type wall socket box. During installation, screws are passed through the mounting holes 121 and screwed into the screw holes of the wall-mounted base box to securely fix the base shell 12 to the wall, achieving quick and reliable installation of the projection floor light. Specifically, the base shell 12 is a load-bearing base shell.

[0027] Rereference Figure 1 Preferably, the pressure cover 11 has an adjustment groove 113 on its surface, and an adjustment port 112 is formed in the groove wall of the adjustment groove 113. The housing assembly 1 also includes a cover plate 13, which can cover the opening of the adjustment groove 113. In specific applications, the main body of the switching component 22 is housed in the bottom housing 12, while a portion of the switching component 22 passes through the adjustment port 112 and extends into the space of the adjustment groove 113, allowing the user to directly move the exposed part within the adjustment groove 113 to switch patterns. After selecting a pattern, the cover plate 13 is closed onto the opening of the adjustment groove 113, thus protecting and shielding the internal operating part of the switching component 22 and the adjustment port 112, preventing dust and accidental contact. Specifically, the cover plate 13 is a cover plate, and the pressure cover 11 is a pressure cover.

[0028] Reference Figure 7 , Figure 7As shown in another structural diagram of the projection floor lamp in this embodiment, preferably, the housing assembly 1 further includes a panel 14 with a second projection port 141. The panel 14 can be covered outside the bottom housing 12, and the second projection port 141 is connected to the first projection port 111. In specific applications, the panel 14 is an outer protective panel covering the cover 11, which can be installed after the internal pattern adjustment is completed, forming the final external protection for the cover 11 and the overall structure of the projection floor lamp. After the panel 14 is installed, the second projection port 141 on the panel 14 is precisely aligned with the first projection port 111 on the cover 11 and remains connected. Thus, the light emitted by the light source 21, after passing through the pattern area on the switching member 22, forms a projection beam that sequentially passes through the first projection port 111 and the second projection port 141, and finally shines out completely to present a clear pattern. This detachable panel 14 design effectively protects the internal structure of the floor lamp, while the second projection port 141 on it serves as the final projection outlet, ensuring a smooth light path and projection effect. Specifically, the panel 14 and the base shell 12 can be detached and installed using a snap-fit ​​structure, which will not be elaborated here.

[0029] Reference Figure 8 , Figure 8 The exploded view of the light source and switching mechanism in the embodiment is shown below. Preferably, the light source 21 includes a controller 211, a light source section 212, a condensing lens 213, and a shaping lens 214. The controller 211 is disposed inside the base housing 12, and the light source section 212 is electrically connected to the controller 211. The light source section 212, the condensing lens 213, the switching mechanism 22, and the shaping lens 214 are arranged sequentially inside the base housing 12. In specific applications, the controller 211 is a PCB circuit board, and the light source section 212 is an LED light source. Its working light path is as follows: The light emitted by the LED light source first illuminates the condensing lens 213, which converges the originally divergent light, making it more concentrated, bright, and uniform. Subsequently, this converged light passes through the pattern hole 2211 of the first rotating wheel 221, the pattern area, and the pattern hole 2211 of the second rotating wheel 222, where the light is cut into the corresponding pattern shape. Finally, the beam of light carrying the pattern reaches the forming lens 214, which acts like a projection lens, optically magnifying, correcting, and clearly projecting the pattern onto the wall or floor via the first projection port 111 and the second projection port 141.

[0030] Reference Figure 9 and Figure 10 , Figure 9 This is an exploded view of the carrier and switching components in the embodiment. Figure 10The exploded view of the carrier in the embodiment shows that, preferably, the housing assembly 1 further includes a carrier 15, which is disposed within the bottom shell 12. A condensing lens 213, a switching element 22, and a forming lens 214 are sequentially arranged on the carrier 15, and the switching element 22 is movably disposed on the carrier 15. In specific applications, the carrier 15 is a support frame. Rotating shafts 2212 are provided at the center positions of the opposite sides of the first rotating disk 221 and the second rotating disk 222. Corresponding rotating grooves 152 are provided within the support frame, and the support frame has receiving slots 153 that can accommodate the first rotating disk 221 and the second rotating disk 222. During assembly, the first rotating disk 221 and the second rotating disk 222 are inserted into the receiving slots. The rotating shafts 2212 of the first rotating disk 221 and the second rotating disk 222 are rotatably disposed within the rotating grooves 152 on both sides of the inner wall of the support frame, thereby allowing the entire switching element 22 to rotate stably and smoothly relative to the support frame. When the user moves the switch 22, the force is transmitted through the rotating shaft 2212, so as to realize the synchronous rotation of the first rotating wheel 221, the second rotating wheel 222 and the projection sheet 223 held therein, thereby driving different pattern areas to enter the light path in sequence.

[0031] Reference Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the bottom shell component in the embodiment. Figure 12 The diagram illustrates the structure of the pressure cap in this embodiment. Specifically, the support member 15 has fixing posts 154 on both sides, and the pressure cap 11 has two opposing support mounting brackets 114. Each support mounting bracket 114 has an engagement opening 1141 at its end that matches the fixing post 154. The engagement opening 1141 has an arc shape slightly larger than 180 degrees, and its inner diameter matches the outer diameter of the fixing post 154. During assembly, the fixing posts 154 on both sides of the support member 15 are aligned with the engagement openings 1141 at the corresponding ends of the support mounting brackets 114. The fixing posts 154 are then pressed into the engagement openings 1141. Because the arc of the engagement opening 1141 is slightly larger than a semicircle, the elastic arms on both sides of the opening will slightly expand elastically when the fixing posts 154 are pressed in. After the fixing posts 154 are fully inserted, the elastic arms rebound, thus clamping the fixing posts 154 within the engagement openings 1141, forming a stable and tight fit. A support frame 122 is provided on the side of the bottom shell 12 facing the cover 11. When the fixing post 154 is inserted into the engagement opening 1141 and the cover 11 is placed on the bottom shell 12, the support frame 122 extends into the engagement opening 1141 and contacts the fixing post 154 to prevent the fixing post 154 from coming out of the engagement opening 1141. Of course, in other embodiments, the fixing post 154 can also be provided on the bottom shell 12, and the support frame 122 can be provided on the side of the cover 11 facing the bottom shell 12; this is not limited here.

[0032] Preferably, the switching component 22 has multiple limiting holes 2213 on its surface, and the carrier component 15 has limiting protrusions 151. When the switching component 22 is moved so that the light source component 21 is aligned with one of the pattern areas, the limiting protrusions 151 extend into one of the limiting holes 2213. In specific applications, the opposite sides of the first rotating wheel 221 and the second rotating wheel 222 are both provided with multiple limiting holes 2213, and the inner wall of the carrier component 15 is provided with two opposing limiting protrusions 151, that is, the carrier component 15 is provided with two opposing elastic strips, and each elastic strip has a limiting protrusion 151. When the user rotates the switch 22 to bring a pattern area to the projection position directly opposite the light source 21, the elastic strip undergoes elastic deformation. Under the action of the elastic force, the limiting protrusion 151 on it is engaged in a corresponding limiting hole 2213 on the rotating wheel. In this way, the cooperation between the limiting hole 2213 and the limiting protrusion 151 not only provides the user with a clear positioning feel, but also keeps the switch 22 in the working position, achieving limiting fixation and preventing accidental rotation or shaking, which helps to maintain the stability of the projected image. Furthermore, the outer edges of the first rotating wheel 221 and the second rotating wheel 222 have multiple spaced teeth, and the inner side of the cover plate 13 has a corresponding limiting groove. It can be understood that when the user needs to adjust the position of the switching element 22, he / she opens the cover plate 13 to move the switching element 22. After the user has adjusted the position of the switching element 22, the limiting protrusion 151 extends into one of the limiting holes 2213 for limiting and positioning. After the cover plate 13 is closed, the teeth of the first rotating wheel 221 and the second rotating wheel 222 extend into the limiting groove on the inner side of the cover plate 13, thereby limiting the position of the switching element 22 a second time and preventing the switching element 22 from rotating or shaking accidentally.

[0033] Preferably, the projection assembly 2 further includes a sensor 23, which is electrically connected to the controller 211. In a specific application, the sensor 23 is a photosensitive cap, which is mounted on the surface of the panel 14 and electrically connected to the controller 211 via wires to obtain operating power and transmit sensing signals. The sensor 23 integrates a human body sensing module and a light sensing module. The human body sensing module (infrared sensor) is used to detect whether a human body is approaching, and the light sensing module (photosensitive sensor) is used to detect the brightness of the ambient light. The controller 211 receives and processes the signals from these two modules and controls the light source 212 to turn on and off accordingly. When the light sensing module detects that the ambient light is below a set threshold (e.g., at night) and the human body sensing module detects that someone is approaching, the controller 211 controls the light source 212 to light up and project. When the human body leaves or the ambient light becomes sufficient (e.g., during the day), the controller controls the light source 212 to turn off. In this way, energy-saving control of "lights on when people come and off when people leave" and intelligent light control of "projection at night and no projection during the day" can be achieved, improving the convenience of use while achieving energy-saving effects.

[0034] In summary, since the switching element 22 has multiple pattern areas, each with a different projection pattern, the light source of the light source element 21 can project different patterns outward through the first projection port 111 after passing through different pattern areas. When the user needs to switch the projection pattern, they only need to move the switching element 22 so that the light source element 21 is aligned with the different pattern area on the switching element 22. In this way, the light source of the light source element 21 can pass through the pattern area and the first projection port 111 and be emitted outward to form different pattern projections, realizing the replacement of the projection pattern to adapt to different application scenarios, while improving convenience and user experience.
