Technical Field

[0001] This application relates to the field of lighting fixtures, and in particular to a night light with projection function. Background Technology

[0002] A night light is a low-brightness light fixture typically used at night. Its main purpose is to provide a soft, reassuring light in the dark, avoiding the inconvenience or danger of complete darkness, or for nighttime illumination.

[0003] Most nightlights on the market include a switch, which needs to be triggered to control the light's brightness. However, users may not easily find the switch in a dark environment, making the nightlight inconvenient to use and even posing a risk of accidental bumping. Furthermore, nightlights are usually only used for illumination, and their function is generally quite limited. Utility Model Content

[0004] To improve the ease of use and versatility of nightlights, this application provides a nightlight with a projection function.

[0005] This application provides a night light with projection function, which adopts the following technical solution: A night light with projection function includes a lampshade and a plug socket that are fixedly connected. The lampshade has a projection cover and a circuit board inside its cavity. The projection cover has multiple light-transmitting holes and is placed on the circuit board. The circuit board has a light source and a photosensitive sensor that are electrically connected.

[0006] By adopting the above technical solution, a night light with integrated projection function is provided. By embedding the projection cover and circuit board within the lampshade and creating multiple light-transmitting holes on the projection cover, the night light can not only provide basic illumination but also project patterns or shadows into the surrounding environment, enhancing its functional versatility. Simultaneously, the electrical connection between the light source and the photosensor enables automatic sensing of ambient light. When the light dims to a certain level, the night light turns on; when the light brightens to a certain level, the night light turns off, improving ease of use and intelligence.

[0007] Optionally, the circuit board is provided with a control switch electrically connected to the light source, and a button is slidably disposed on the lampshade, the button being able to slide to trigger the control switch.

[0008] By adopting the above technical solution, a sliding button electrically connected to the control switch is set on the circuit board. Users can trigger the switch of the night light with a simple sliding action. When the night light is not needed, the power to the night light is turned off by pressing the button. There is no need to unplug the night light from the wall socket. When it is needed next time, just press the button. It is convenient to use and improves the convenience of user operation.

[0009] Optionally, the projection cover surface is an arc surface.

[0010] By adopting the above technical solution, the projection mask is designed with a curved surface, which allows light to produce a softer and more diffused projection effect when passing through the light-transmitting hole. The curved structure helps to distribute light evenly, avoiding harsh light spots or edges, and improving the aesthetics and visual comfort of the projected pattern.

[0011] Optionally, the lampshade is spherical.

[0012] By adopting the above technical solution, the lampshade is designed in a spherical shape, which is not only more aesthetically pleasing and modern in appearance, but also ergonomically designed for easy gripping and placement. The spherical structure also helps to scatter light in all directions, allowing the nightlight to provide uniform illumination and projection effects from different angles.

[0013] Optionally, the lampshade includes a detachably connected hemispherical upper cover and a lower cover, the projection cover being hemispherical and located within the inner cavity of the upper cover.

[0014] By adopting the above technical solution, the lampshade is designed as a detachable upper and lower cover, with the projection cover placed inside the upper cover, making the assembly and maintenance of the night light more convenient. Users or manufacturers can easily disassemble the lampshade to clean or replace internal components, such as the projection cover or circuit board, improving the maintainability and lifespan of the product.

[0015] Optionally, the inner cavity of the lower cover is provided with a positioning plate and a plurality of limiting plates. Each of the limiting plates is arranged along the extension direction of the plate surface of the positioning plate. The plate surfaces of the positioning plate and the limiting plate are perpendicular. A plurality of positioning blocks that abut against the circuit board are formed on both the positioning plate and the limiting plate. A plurality of limiting blocks that abut against the upper cover and the projection cover are formed on the limiting plate.

[0016] By adopting the above technical solution, a positioning plate and multiple limiting plates are set inside the lower cover, and positioning blocks and limiting blocks are formed on them, achieving precise positioning of the circuit board, projection cover, and upper cover. This structure effectively prevents internal components from shifting or loosening during use, improving the structural stability and reliability of the product.

[0017] Optionally, a cleaning component is also included, which is provided with a cleaning sponge. The cleaning component is movably connected to the lampshade, so as to drive the cleaning sponge to wipe the outer surface of the lampshade. The cleaning component can also be fixedly connected to the plug socket.

[0018] By adopting the above technical solution and adding a cleaning component with a cleaning sponge, users can easily wipe the outer surface of the lampshade to maintain its light transmission and aesthetics. The cleaning component can also be fixed to the plug socket for easy storage and retrieval, preventing it from blocking the light emitted from the lampshade and further enhancing the product's practicality and user experience.

[0019] Optionally, the lampshade is a rotating body, the structure of the cleaning component is adapted to the structure of the lampshade, a rotating rod is formed on the cleaning component, and a rotating groove for inserting the rotating rod is provided on the lampshade. The central axis of the rotating rod is collinear with the central axis of the lampshade, and the cleaning component can rotate on the lampshade around the central axis of the rotating rod.

[0020] By adopting the above technical solution, the cleaning component is designed to fit the lampshade structure, and a rotating rod is incorporated into the rotating groove, allowing the cleaning component to rotate and wipe around the central axis of the lampshade, achieving comprehensive cleaning of the lampshade's outer surface. This design not only simplifies operation but also improves cleaning efficiency and coverage.

[0021] Optionally, the cleaning component includes two identical and detachably connected cleaning rods. Inserts are formed on the surfaces of the two cleaning rods that are close to each other, and slots are provided on the surfaces of the two cleaning rods that are close to each other. The slots on the cleaning rods are for inserts on the adjacent cleaning rods to be inserted.

[0022] By adopting the above technical solution, the cleaning component is designed as two detachably connected cleaning rods, with inserts and slots on their contact surfaces, allowing for flexible assembly and disassembly. This modular design improves the maintainability and usability of the cleaning component, and the identical cleaning rod structure allows for standardized production, reducing processing costs.

[0023] Optionally, slots are provided on both opposite surfaces of the plug socket, and the two slots are respectively for inserting different cleaning rods. When the insert is inserted into the slot, the surfaces of the two cleaning rods that are far apart from each other are coplanar with the surface of the plug socket that is far away from the lampshade.

[0024] By adopting the above technical solution, a slot is opened on the plug socket for the insertion of the cleaning rod, allowing the cleaning component to be securely stored in the plug socket when not in use, preventing loss. At the same time, the coplanar design of the cleaning rod and the plug socket allows the cleaning rod to fit snugly against the wall, providing auxiliary support for the nightlight and minimizing the risk of the plug socket becoming loose.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. This allows the night light to not only provide basic lighting but also project patterns or shadows into the surrounding environment, enhancing its functional versatility. At the same time, it enables the night light to automatically turn on in dark environments, improving its ease of use and level of intelligence. 2. The cleaning component can rotate and wipe around the central axis of the lampshade to achieve a thorough cleaning of the outer surface of the lampshade. This design is not only easy to operate, but also improves cleaning efficiency and coverage. 3. When not in use, the cleaning device can be securely stored on the plug socket to prevent loss. At the same time, the design of the cleaning rod and the plug socket being coplanar allows the cleaning rod to fit against the wall, which can provide auxiliary support for the night light and minimize the risk of the plug socket coming loose.

[0032] The following combination Figures 1-5 This application will be described in further detail.

[0033] Example 1: Embodiment 1 of this application discloses a night light with projection function. (See also...) Figure 1The night light with projection function includes a lampshade 1 and a plug socket 2. The lampshade 1 and the plug socket 2 are fixedly connected by adhesive or other means, which facilitates the overall installation and use of the night light. The night light can be used by simply inserting it into the socket through the plug socket 2. This achieves the effect of the night light being stably connected to the power supply. This is because the fixed connection ensures that the two will not easily separate, ensuring the stability of the night light during use.

[0034] Reference Figure 1 The lampshade 1 serves to protect the internal light source and scatter and focus the light for better illumination. The lampshade 1 can be made of transparent or semi-transparent plastic, such as polycarbonate, which offers good light transmission and impact resistance. The lampshade 1 is spherical, which is not only more aesthetically pleasing and modern in appearance but also ergonomically designed for easy gripping and placement. The spherical structure also facilitates all-around light scattering, allowing the nightlight to provide uniform illumination and projection effects from different angles. This is because the spherical surface reflects and refracts light in all directions, reducing blind spots. In other embodiments, the lampshade 1 can also be other shapes.

[0035] Reference Figure 1 and Figure 2 The lampshade 1 includes a detachably connected hemispherical upper cover 11 and lower cover 12, which together form the inner cavity of the lampshade 1. The upper cover 11 and lower cover 12 are generally made of plastic and are detachably connected via threaded connections, snap-fit ​​connections, or magnetic connections. This design makes the assembly and maintenance of the night light more convenient. Users or manufacturers can easily disassemble the lampshade 1 to clean or replace internal components, improving the maintainability and lifespan of the product.

[0036] Reference Figure 2A positioning plate 9 and multiple limiting plates 100 are fixedly connected within the inner cavity of the lower cover 12. The positioning plate 9 and limiting plates 100 are generally made of plastic or metal and possess a certain strength and hardness. Each limiting plate 100 is arranged along the extension direction of the surface of the positioning plate 9, and the surfaces of the positioning plate 9 and limiting plates 100 are perpendicular. They are installed in the inner cavity of the lower cover 12 by integral molding, adhesive bonding, or screw fixing. Multiple positioning blocks 110 are fixedly connected to both the positioning plate 9 and the limiting plates 100. Multiple limiting blocks 101 are also fixedly connected to the ends of the limiting plates 100. These positioning blocks 110 and limiting blocks 101 can be protruding structures, formed by injection molding or machining. The limiting blocks 101 are distributed around the central axis of the lamp cover 1, and there are two rings of limiting blocks 101. The height of the limiting blocks 101 in the inner ring is higher than that in the outer ring, so that the limiting blocks 101 in the inner ring and the limiting blocks 101 in the outer ring are stepped. The limiting blocks 101 in the outer ring are used to abut against the inner wall of the upper cover 11 to position the upper cover 11.

[0037] Reference Figure 2 A projection mask 3 is placed inside the inner cavity of the upper cover 11. A limiting block 101 located on the inner ring abuts against the inner wall of the projection mask 3 to position it. The projection mask 3 is made of opaque plastic and is hemispherical with an inner cavity (bowl-shaped). The structural dimensions of the projection mask 3 are adapted to the structural dimensions of the upper cover 11. Multiple light-transmitting holes 31 are provided on the projection plate. These light-transmitting holes 31 can be circular, square, star-shaped, or other shapes to project different patterns or shadows. In other embodiments, the side surface of the projection mask 3 can also be flat.

[0038] Reference Figure 2 A circuit board 4 is fixedly connected to the inner cavity of the lower cover 12. The circuit board 4 is connected to the positioning plate 9 by bolts. The projection cover 3 is placed on the circuit board 4, so that the circuit board 4 is located in the inner cavity of the projection cover 3. The positioning block 110 is used to abut against the circuit board 4 to position the circuit board 4. The setting of the positioning block 110 and the limiting block 101 realizes the precise positioning of the circuit board 4, the projection cover 3 and the upper cover 11, effectively preventing the internal components from shifting or loosening during use, and improving the structural stability and reliability of the product.

[0039] Reference Figure 2 The circuit board 4 includes a substrate on which electronic components are mounted. The substrate is generally made of a material with good insulation properties, such as fiberglass board. The electronic components include a light source 5 and a photosensitive sensor 6. The light source 5 can be an LED lamp bead, which has the characteristics of high luminous efficiency and low energy consumption. The photosensitive sensor 6 can sense the intensity of ambient light. They are fixed on the substrate by welding and electrically connected by circuit lines.

[0040] Reference Figure 2 The circuit board 4 also features a control switch 7 electrically connected to the light source 5. This control switch 7 is typically a microswitch, characterized by its small size and high sensitivity. It is fixed to the circuit board 4 by soldering and electrically connected to the light source 5 via circuit lines. A button 8 is slidably mounted on the lampshade 1. Button 8 is usually made of plastic with a non-slip surface treatment, such as textured or frosted finish. A sliding groove is provided on the lampshade 1, and button 8 slides along this groove. Button 8 can slide to trigger the control switch 7. When the user needs to turn off the night light, simply slide button 8 to trigger the control switch 7, cutting off the power to the light source 5. There is no need to unplug the night light from the wall socket. The next time the light is needed, simply slide button 8, making it convenient and improving user operation.

[0041] The implementation principle of a night light with projection function in Embodiment 1 of this application is as follows: When the ambient light is dim, the photosensor 6 senses the change in light and transmits the signal to the circuit board 4. The circuit board 4 controls the light source 5 to emit light. The light passes through the light-transmitting hole 31 on the projection cover 3 and projects patterns or shadows into the surrounding environment, which not only provides basic lighting but also enhances the functional versatility of the night light. At the same time, due to the electrical connection between the light source 5 and the photosensor 6, automatic sensing of ambient light is achieved, enabling the night light to automatically start in dark environments, improving the convenience and intelligence of use.

[0042] Example 2: Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the night light with projection function also includes a cleaning component 120. The cleaning component 120 includes two identical and detachably connected cleaning rods 122. The cleaning rods 122 are arc-shaped, and the cross-sectional shape of the cleaning component 120 is semi-circular. The cleaning rods 122 are generally made of plastic, which is lightweight and corrosion-resistant. Inserts 123 are formed on the surfaces of the two cleaning rods 122 that are close to each other. The inserts 123 can be square, round, or other shapes, and are integrally formed with the cleaning rods 122 by injection molding. Slots 124 are provided on the surfaces of the two cleaning rods 122 that are close to each other. The shape of the slots 124 is adapted to the inserts 123, and the slots 124 on the cleaning rods 122 allow the inserts 123 on adjacent cleaning rods 122 to be inserted.

[0043] The cleaning component 120 is designed as two detachably connected cleaning rods 122, with inserts 123 and slots 124 provided on their contacting surfaces, allowing for flexible assembly and disassembly of the cleaning component 120. This modular design improves the maintainability and usability of the cleaning component 120, and the identical structure of the cleaning rods 122 allows for standardized production, reducing processing costs. In other embodiments, the two cleaning rods 122 can be detachably connected via bolts or snap-fit ​​connections.

[0044] Reference Figure 3 A cleaning sponge 130 is fixedly connected to the concave surface of the cleaning rod 122 by means of Velcro, adhesive, or clips. The cleaning sponge 130 has good water absorption and cleaning ability, and can effectively clean dust and stains on the surface of the lampshade 1. The addition of the cleaning component 120 with the cleaning sponge 130 allows users to easily wipe the outer surface of the lampshade 1, maintaining its light transmission and appearance.

[0045] Reference Figure 3 and Figure 5 A rotating rod 121 is fixedly connected to the cleaning component 120. The rotating rod 121 is generally integrally formed with the cleaning rod 122, and is made of the same material as the cleaning rod 122. The rotating rod 121 is a cylindrical rod. A rotating groove 13 is provided on the lampshade 1 for the rotating rod 121 to be inserted and rotated. The central axis of the rotating rod 121 is collinear with the central axis of the lampshade 1, allowing the cleaning component 120 to rotate around the central axis of the rotating rod 121 on the lampshade 1. The combination of the rotating rod 121 and the rotating groove 13 allows the cleaning component 120 to rotate and wipe around the central axis of the lampshade 1, achieving a thorough cleaning of the outer surface of the lampshade 1. This design not only simplifies operation but also improves cleaning efficiency and coverage.

[0046] In other embodiments, the lampshade 1 can be of other shapes, as long as it is a rotating body, and the structural shape of the cleaning component 120 is adapted to the structural shape of the lampshade 1. In other embodiments, the lampshade 1 and the cleaning component 120 can be of any shape, and the cleaning component 120 can be movably connected to the lampshade 1, driving the cleaning sponge 130 to wipe the outer surface of the lampshade 1.

[0047] Reference Figure 3 and Figure 4 and Figure 5The plug socket 2 has slots 21 on its two opposing surfaces arranged horizontally. The shape of the slots 21 matches the inserts 123 on the cleaning rod 122. Each slot 21 allows for the insertion of a different cleaning rod 122's insert 123. When the insert 123 is inserted into the slot 21, the surfaces of the two cleaning rods 122 that are far apart are coplanar with the surface of the plug socket 2 that is far from the lampshade 1. The slots 21 on the plug socket 2 allow the cleaning component 120 to be securely stored on the plug socket 2 when not in use, preventing loss and blocking light from the lampshade 1. Simultaneously, the coplanar design of the cleaning rod 122 and the plug socket 2 allows the cleaning rod 122 to fit snugly against the wall, providing auxiliary support for the nightlight and minimizing the risk of the plug socket 2 becoming loose.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
