Description

Technical Field

[0001] This disclosure pertains to the field of lighting, specifically relating to a night light, lighting device, and electrical device. Background Technology

[0002] A nightlight is a light fixture used at night or in dim lighting conditions. Typically, the nightlight's prongs are inserted into a socket to position it. However, the nightlight may block other sockets, rendering them unusable. While this can sometimes be avoided by inserting the prongs into a different socket or reversing the nightlight's orientation, this is not always feasible. For example, reversing the nightlight's orientation can unintentionally change the direction of the light, causing problems such as glare. In some existing technologies, the nightlight's body is designed to rotate about an axis perpendicular to the socket surface when the prongs are inserted into a socket. However, this rotation may require significant lateral space, potentially causing interference with surrounding objects such as furniture. Utility Model Content

[0003] This disclosure provides a night light comprising: a housing; a light source for emitting light, housed within the housing; and a plug connected to the housing and including pins for insertion into a socket; the night light further comprising: a guide rail disposed within the housing and configured to guide linear movement of the plug relative to the housing; and an intermediate conductor configured to electrically contact the pins to electrically connect the pins and the light source.

[0004] In this disclosure, by setting a guide rail and an intermediate conductor, the plug and housing can move linearly relative to each other, allowing the housing to avoid the socket, thus facilitating user operation. Furthermore, compared to rotation, linear movement does not change the orientation of the nightlight, ensuring that the nightlight does not occupy lateral space or cause glare due to adjustment, thereby improving the user experience.

[0005] Furthermore, the guide rail is integral with at least a portion of the housing.

[0006] In this disclosure, by integrating the guide rail with at least a portion of the housing, the guide rail and housing can be arranged compactly together, thereby facilitating the miniaturization of the night light.

[0007] Furthermore, the guide rail includes a narrow hole provided on the housing, through which the pin passes.

[0008] In this disclosure, by setting a narrow hole, the night light can have a relatively simple structure, making the night light easy to implement and thus reducing the cost of the night light.

[0009] Furthermore, the night light also includes a dustproof part configured to cover the portion of the narrow hole not occupied by the pin.

[0010] In this disclosure, by providing a dustproof section, external water or dust can be prevented from entering the interior of the housing through the narrow opening, thus enabling the night light to have high reliability. Furthermore, by providing the dustproof section, relative movement between the plug and the housing is hindered, allowing the plug to be stably held in the set position on the guide rail.

[0011] Furthermore, the night light also includes a circuit board, on which the light source and the intermediate conductor are integrated.

[0012] In this disclosure, by integrating the light source and the intermediate conductor onto a circuit board, the light source, circuit board, and intermediate conductor can be arranged compactly together, which is beneficial for the miniaturization of the night light.

[0013] Furthermore, the intermediate conductor is configured to make sliding contact with the pin.

[0014] In this disclosure, by configuring the intermediate conductor to slide in contact with the pins, the night light can have a simpler structure, making the night light easier to implement and thus reducing the cost of the night light.

[0015] Furthermore, the intermediate conductor is continuous.

[0016] In this disclosure, by providing a continuous intermediate conductor, the pins and the intermediate conductor can maintain electrical contact during the movement of the plug relative to the housing, so that the relative movement of the plug and the housing does not affect the power supply to the light source.

[0017] Furthermore, the intermediate conductor includes a plurality of discrete portions configured to allow the pin to selectively contact one of the discrete portions to electrically connect the pin and the light source.

[0018] In this disclosure, by setting multiple discrete parts, if one or some of these discrete parts are damaged, the remaining discrete parts are not easily affected by the damaged discrete parts, so that the pins can still be electrically connected to the light source through the remaining undamaged discrete parts, thereby enabling the night light to have high reliability.

[0019] Furthermore, the pin is configured to remain in contact with at least one of the plurality of discrete portions during the movement of the plug relative to the housing.

[0020] In this disclosure, by ensuring that the pins are always in contact with at least one discrete part, the pins and the intermediate conductor can maintain electrical contact during the movement of the plug relative to the housing, so that the relative movement of the plug and the housing does not affect the power supply to the light source.

[0021] Furthermore, the discrete portion is configured to elastically deform under the push of the pin.

[0022] In this disclosure, by causing the discrete portion to elastically deform under the push of the pin, the pin and the discrete portion can be tightly abutted together by elastic force, enabling stable electrical contact between the pin and the discrete portion, thereby improving the performance of the electrical device. Furthermore, a certain frictional force can be generated between the pin and the discrete portion, which can impede relative movement between the plug and the housing, allowing the plug to be stably held in a set position on the guide rail.

[0023] Furthermore, the pin includes a contact for contacting the discrete portion, the two opposite ends of the contact in the longitudinal direction of the guide rail being tilted away from the discrete portion.

[0024] In this disclosure, by tilting the two ends of the contacts upwards, the plug and the housing can move smoothly relative to each other, making the night light easy to use.

[0025] Furthermore, the intermediate conductor also includes a base adjacent to the plurality of discrete portions, the plurality of discrete portions being configured to be electrically connected to the light source via the same base.

[0026] In this disclosure, by setting a base, the intermediate conductor can have a compact structure, which is beneficial for the miniaturization of the night light.

[0027] Furthermore, the intermediate conductor is a flexible conductor and includes a first end and a second end, the first end being fixed to the plug and electrically connected to the pins, and the second end being fixed to the housing and electrically connected to the light source.

[0028] In this disclosure, by setting a flexible intermediate conductor, the night light can have a relatively simple structure, making the night light easy to implement and thus reducing the cost of the night light.

[0029] Furthermore, the first end is configured to approach the second end as the plug moves from both ends of the guide rail toward the middle portion of the guide rail.

[0030] In this disclosure, by bringing the first end closer to the second end as the plug moves from both ends of the guide rail to the middle portion of the guide rail, the intermediate conductor can have a shorter length, thereby reducing the cost of the nightlight. Furthermore, this arrangement prevents the intermediate conductor from tangling or interfering with other components, resulting in higher reliability for the nightlight.

[0031] This disclosure also provides a lighting device, comprising: a housing; a light source for emitting light, housed within the housing; and a plug connected to the housing and including pins for insertion into a socket; the lighting device further comprising: a guide rail disposed within the housing and configured to guide linear movement of the plug relative to the housing; and an intermediate conductor configured to electrically contact the pins to electrically connect the pins and the light source.

[0032] Furthermore, the guide rail is integral with at least a portion of the housing.

[0033] Furthermore, the guide rail includes a narrow hole provided on the housing, through which the pin passes.

[0034] This disclosure also provides an electrical device comprising: a housing; a light source for emitting light, housed within the housing; and a plug connected to the housing and including pins for insertion into a socket; the electrical device further comprising: a guide rail disposed within the housing and configured to guide linear movement of the plug relative to the housing; and an intermediate conductor configured to electrically contact the pins to electrically connect the pins and the light source.

[0035] Furthermore, the guide rail is integral with at least a portion of the housing.

[0036] Furthermore, the guide rail includes a narrow hole provided on the housing, through which the pin passes. Attached Figure Description

[0072] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0073] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0074] The following is for reference. Figures 1 to 5 The first embodiment of this disclosure is described.

[0075] refer to Figures 1 to 5 A first embodiment of this disclosure provides an electrical device including a housing 230, a light source 210 for emitting light, a plug 100, a guide rail 220, and an intermediate conductor 300. The light source 210 is housed within the housing 230. The plug 100 is connected to the housing 230 and includes pins 110 for insertion into sockets (not shown). The guide rail 220 is disposed within the housing 230 and configured to guide linear movement of the plug 100 relative to the housing 230. The intermediate conductor 300 is configured to make electrical contact with the pins 110 to electrically connect the pins 110 and the light source 210.

[0076] As an example, an electrical device can be a lighting device, such as a night light.

[0077] As an example, housing 230 may include a first housing portion 231 and a second housing portion 232, the first housing portion 231 being detachably connected to the second housing portion 232. For example, the second housing portion 232 may be provided with an opening 233 through which light emitted by the light source 210 can pass. Preferably, the opening 233 may be oriented along the longitudinal direction L of the guide rail 220.

[0078] As an example, the light source 210 can be an LED light source, such as the light source 210 may include one or more LED beads.

[0079] As an example, the plug 100 may also include a body 120 that can support the prongs 110. For example, the body 120 may be made of an insulating material, and the two prongs 110 may pass through the body 120 and be spaced apart by the body 120.

[0080] It should be understood that the movement of plug 100 relative to housing 230 can be either the movement of plug 100 or the movement of housing 230. For example, when prong 110 is inserted into the socket, plug 100 can be stationary while housing 230 moves. When prong 110 is separated from the socket, housing 230 can be stationary while plug 100 moves. Of course, in other cases, plug 100 and housing 230 can also move simultaneously.

[0081] In this disclosure, by setting the guide rail 220 and the intermediate conductor 300, the plug 100 and the housing 230 can move linearly relative to each other, allowing the housing 230 to avoid the socket, thus facilitating user operation. Furthermore, compared to rotation, linear movement does not change the orientation of the electrical device, ensuring that the device does not occupy lateral space or cause glare due to adjustment, thereby improving the user experience.

[0082] As an example, the intermediate conductor 300 can be made of metal, such as copper.

[0083] refer to Figure 2 The guide rail 220 is integral with at least a portion of the housing 230.

[0084] As an example, the guide rail 220 can be integral with the first housing portion 231. For instance, the guide rail 220 and the first housing portion 231 can be obtained by injection molding.

[0085] In this disclosure, by integrating the guide rail 220 with at least a portion of the housing 230, the guide rail 220 and the housing 230 can be arranged compactly together, thereby facilitating the miniaturization of the electrical device.

[0086] refer to Figure 2 The guide rail 220 includes a narrow hole 221 provided on the housing 230, through which the pin 110 passes.

[0087] As an example, the guide rail 220 may include two parallel apertures 221, through which two pins 110 may pass respectively.

[0088] As an example, the guide rail 220 may also include a guide groove 222, in which the main body 120 can be positioned and guided. For example, a narrow hole 221 may be provided at the bottom of the guide groove 222.

[0089] As an example, the electrical device may also include a cover plate 400, which can cover the guide groove 222 and hold the body 120 within the guide groove 222.

[0090] In this disclosure, by providing the narrow hole 221, the electrical device can have a simpler structure, making the electrical device easier to implement and thus reducing the cost of the electrical device.

[0091] refer to Figures 2 to 5 The electrical device also includes a dustproof part 240, which is configured to cover the portion of the orifice 221 not occupied by the pin 110.

[0092] As an example, the dustproof part 240 can be made of an elastic material, such as silicone.

[0093] As an example, the dustproof part 240 can be integral with at least a portion of the housing 230. For instance, if the first housing portion 231 is made of plastic, the dustproof part 240 and the first housing portion 231 can be obtained by two-color injection molding.

[0094] As an example, such as Figure 3 As shown, the dustproof part 240 may include a plurality of first dustproof teeth 241 and a plurality of second dustproof teeth 242. The plurality of first dustproof teeth 241 and the plurality of second dustproof teeth 242 may be oriented oppositely in the transverse direction T of the guide rail 220, and may be arranged alternately in the longitudinal direction L of the guide rail 220.

[0095] In this disclosure, by providing a dustproof section 240, external water or dust can be prevented from entering the interior of the housing 230 through the narrow hole 221, thereby enabling the electrical device to have high reliability. Furthermore, by providing the dustproof section 240, relative movement between the plug 100 and the housing 230 is prevented, allowing the plug 100 to be stably held in a predetermined position on the guide rail 220. This configuration is particularly advantageous when the guide rail 220 is oriented vertically.

[0096] refer to Figure 4 and Figure 5 The electrical device also includes a circuit board 250, a light source 210, and an intermediate conductor 300 integrated on the circuit board 250.

[0097] As an example, circuit board 250 may include a first circuit board portion 251 and a second circuit board portion 252 perpendicular to each other. An intermediate conductor 300 may be disposed on the first circuit board portion 251, and a light source 210 may be disposed on the second circuit board portion 252. For example, the first circuit board portion 251 may be parallel to the cover plate 400 and disposed between the cover plate 400 and the first housing portion 231, and the second circuit board portion 252 may pass through the cover plate 400.

[0098] In this disclosure, by integrating the light source 210 and the intermediate conductor 300 onto the circuit board 250, the light source 210, the circuit board 250, and the intermediate conductor 300 can be arranged compactly together, thereby facilitating the miniaturization of the electrical device.

[0099] refer to Figure 5 The intermediate conductor 300 is configured to make sliding contact with the pin 110.

[0100] As an example, pin 110 is configured to remain in contact with intermediate conductor 300 during movement of plug 100 relative to housing 230. In other examples, pin 110 may be disengaged from intermediate conductor 300 when plug 100 is located at certain positions on rail 220, thereby turning off the electrical device (i.e., light source 210 does not emit light).

[0101] In this disclosure, by configuring the intermediate conductor 300 to slide in contact with the pin 110, the electrical device can have a simpler structure, making the electrical device easier to implement and thus reducing the cost of the electrical device.

[0102] refer to Figure 5 The intermediate conductor 300 is continuous.

[0103] As an example, the intermediate conductor 300 can have an elongated shape. For instance, the intermediate conductor 300 can be parallel to the guide rail 220 and have approximately the same length.

[0104] In this disclosure, by providing a continuous intermediate conductor 300, the pin 110 and the intermediate conductor 300 can maintain electrical contact during the movement of the plug 100 relative to the housing 230, so that the relative movement of the plug 100 and the housing 230 does not affect the power supply to the light source 210.

[0105] The following is for reference. Figure 6 and Figure 7 A second embodiment of this disclosure is described. The second embodiment is a variation of the first embodiment. For features that are the same as or similar to those in the first embodiment, the same reference numerals are used in this embodiment, and detailed descriptions of these features are omitted.

[0106] refer to Figure 7The intermediate conductor 300 includes a plurality of discrete portions 310, which are configured to allow the pin 110 to selectively contact one of the discrete portions 310 to electrically connect the pin 110 and the light source 210.

[0107] As an example, multiple discrete parts 310 can be arranged side by side in the longitudinal direction L of the guide rail 220.

[0108] In this disclosure, by providing multiple discrete parts 310, if one or some of these discrete parts 310 are damaged, the remaining discrete parts 310 are not easily affected by the damaged discrete parts 310, so that the pin 110 can still be electrically connected to the light source 210 through the remaining undamaged discrete parts 310, thereby enabling the electrical device to have high reliability.

[0109] refer to Figure 6 The pin 110 is configured to always be in contact with at least one of the plurality of discrete portions 310 during the movement of the plug 100 relative to the housing 230.

[0110] As an example, pin 110 may be configured to always be in contact with at least two adjacent discrete portions 310 of a plurality of discrete portions 310 during movement of plug 100 relative to housing 230. For example, pin 110 may be configured to be in contact with up to three adjacent discrete portions 310 of a plurality of discrete portions 310 during movement of plug 100 relative to housing 230.

[0111] In this disclosure, by ensuring that the pin 110 is always in contact with at least one discrete portion 310, the pin 110 and the intermediate conductor 300 are able to maintain electrical contact during the movement of the plug 100 relative to the housing 230, so that the relative movement of the plug 100 and the housing 230 does not affect the power supply to the light source 210.

[0112] refer to Figure 6 The discrete part 310 is configured to elastically deform under the push of the pin 110.

[0113] As an example, the discrete portion 310 may have a flat shape and be configured to oscillate elastically. For example, the discrete portion 310 may be a copper sheet capable of oscillating elastically.

[0114] In this disclosure, by causing the discrete portion 310 to elastically deform under the push of the pin 110, the pin 110 and the discrete portion 310 can be tightly pressed together by elastic force, enabling stable electrical contact between the pin 110 and the discrete portion 310, thereby improving the performance of the electrical device. Furthermore, a certain amount of friction can be generated between the pin 110 and the discrete portion 310, which can prevent relative movement between the plug 100 and the housing 230, allowing the plug 100 to be stably held in a set position on the guide rail 220.

[0115] refer to Figure 6 The pin 110 includes a contact 111 for contacting the discrete part 310, and the two opposite ends of the contact 111 in the longitudinal direction of the guide rail 220 are raised in a direction away from the discrete part 310.

[0116] As an example, pin 110 can be formed integrally from a sheet of material. For instance, pin 110 can be obtained by methods such as stamping or bending.

[0117] In this disclosure, by tilting the two ends of the contact 111, the plug 100 and the housing 230 can move smoothly relative to each other, making the electrical device easy to use.

[0118] refer to Figure 7 The intermediate conductor 300 also includes a base 320 adjacent to a plurality of discrete portions 310, the plurality of discrete portions 310 being configured to be electrically connected to the light source 210 via the same base 320.

[0119] As an example, the base 320 may be parallel to the first circuit board portion 251, and the discrete portion 310 may extend from the base 320 and be at an angle to the base 320. For example, the discrete portion 310 and the base 320 may be formed in a generally V-shaped configuration.

[0120] In this disclosure, by providing the base 320, the intermediate conductor 300 can have a compact structure, which is beneficial for the miniaturization of electrical devices.

[0121] The following is for reference. Figure 8 A third embodiment of this disclosure is described. The third embodiment is a variation of the first embodiment. For features that are the same as or similar to those in the first embodiment, the same reference numerals are used in this embodiment, and detailed descriptions of these features are omitted.

[0122] refer to Figure 8 The intermediate conductor 300 is a flexible conductor and includes a first end 330 and a second end 340. The first end 330 is fixed to the plug 100 and electrically connected to the pin 110, and the second end 340 is fixed to the housing 230 and electrically connected to the light source 210.

[0123] As an example, the intermediate conductor 300 can have an elongated shape. For instance, the intermediate conductor 300 can be part of a wire.

[0124] As an example, the second end 340 can be disposed on the circuit board 250, for example, it can be disposed on the first circuit board portion 251.

[0125] In this disclosure, by providing a flexible intermediate conductor 300, the electrical device can have a simpler structure, making the electrical device easier to implement and thus reducing the cost of the electrical device.

[0126] refer to Figure 8 The first end 330 is configured to approach the second end 340 as the plug 100 moves from both ends of the guide rail 220 to the middle portion of the guide rail 220.

[0127] In this disclosure, by bringing the first end 330 closer to the second end 340 as the plug 100 moves from both ends of the guide rail 220 to the middle portion of the guide rail 220, the intermediate conductor 300 can have a shorter length, thereby reducing the cost of the electrical device. Furthermore, this arrangement prevents the intermediate conductor 300 from tangling or interfering with other components, resulting in higher reliability of the electrical device.

[0128] The above are merely preferred embodiments of this disclosure. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this disclosure, and these improvements and modifications should also be considered within the scope of protection of this disclosure.
