Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of an illumination device 10 provided in the present application. It should be noted that fig. 1 schematically illustrates X, Y and Z directions of the lighting device, mainly for illustrating XY, XZ and YZ planes, so as to facilitate the corresponding description hereinafter. Therefore, all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present application are mainly used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in fig. 1), and if the specific posture is changed, the directional indicator is changed accordingly.

In the embodiment of the present application, the lighting device 10 may be a lamp such as a desk lamp, a wall lamp, a floor lamp, etc. In the embodiment of the present application, the lighting device 10 is exemplified as a desk lamp. The lighting device 10 may include a lamp body assembly 11, a bracket assembly 12, and a control assembly 13. Wherein the bracket assembly 12 is used for connecting and supporting the lamp body assembly 11.

Specifically, the stand assembly 12 may include a light pole 121, a support pole 122, and a base 123. The support rod 122 is disposed between the lamp post 121 and the base 123.

The base 123 is primarily used to support the lighting device 10 as a whole to increase the stability of the lighting device 10 in the overall structure. The base 123 is connected to one end of the supporting rod 122 away from the lamp body assembly 11. In some embodiments, the base 123 may be a disk-like structure, a ring-like structure, a block-like structure, etc. to facilitate placement of the lighting device 10 on a carrying surface of a desk, a bedside table, etc. In other embodiments, the base 123 may also be a clip structure or the like to facilitate holding the lighting device 10 to the edge of a desk, a bedside table, or the like.

The lamp post 121 is mainly used for supporting the lamp body assembly 11, so that the lamp body assembly 11 can at least form a certain illumination area on the bearing surface, thereby satisfying the daily illumination of a user. The lamp post 121 may be a column structure, a plate structure, etc., and the lamp post 121 is connected to one end of the supporting rod 122 far away from the base 123.

The supporting rod 122 is mainly used for connecting the lamp post 121 and the base 123, so that a certain distance is kept between the lamp post 121 and the base 123, and the lamp body assembly 11 forms a complete illumination area. Preferably, one end of the supporting rod 122 is inserted into the base 123.

In the embodiment of the present application, the lighting device 10 may further include a wire 15. The bracket assembly 12 may be hollow, so that the wires 15 can be inserted into the bracket assembly 12, and the wires 15 are hidden in the lighting device 10, thereby increasing the uniformity of the lighting device 10 in appearance structure.

Further, the lamp body assembly 11 includes at least one lamp body, which may be a bar structure, a disc structure, a ring structure, etc., so as to satisfy the daily illumination of the user. The lead wire 15 is electrically connected to the lamp body in the lamp body assembly 11, and is mainly used for guiding electric energy to the lamp body so that the lamp body can emit light.

Referring to fig. 2 in combination, fig. 2 is a partially exploded view of the bracket assembly 12 of fig. 1. It should be noted that the bracket assembly 12 is illustrated in fig. 2, mainly to implicitly illustrate one possible assembly relationship between the supporting rod 122 and the base 123. The conductor 15 is illustrated in fig. 2, also primarily to implicitly illustrate one possible routing of the conductor 15.

The base 123 may include a bottom plate 1231 and a front plate 1232, wherein the bottom plate 1231 and the front plate 1232 enclose a receiving space 1230. The accommodating space 1230 is provided with a control board 125 therein, and the control board 125 is electrically connected to the lamp body assembly 11. The base 123 is primarily for supporting the lighting device 10 as a whole. The control board 125 is mainly used for converting the user's operation into a corresponding control signal so as to control the lamp body assembly 11. Wherein the control board 125 can be electrically connected with the lamp body assembly 11 through the wire 15.

In some embodiments, base 123 may further include a weight 1233. The panel 1232 can be assembled with the bottom plate 1231 by one or a combination of assembling manners such as clamping, gluing, riveting, screwing and the like, and the two can form an accommodating space 1230 with a certain volume; the weight 1233 and the control board 125 are accommodated in the accommodating space 1230. Further, the weight 1233 may be made of a material with a greater density, so that when the lighting device 10 is placed on the bearing surface, the weight 1233 can lower the center of gravity of the lighting device 10, thereby increasing the stability of the lighting device 10 in the overall structure.

The weight 1233 may be a horseshoe nail-shaped structure, a disc-shaped structure, an annular structure, etc., and its density may be as high as possible. The weight 1233 may be assembled with the bottom plate 1231 by one or a combination of clamping, gluing, riveting, screwing, and the like. With such an arrangement, on one hand, the weight 1233 is convenient to lower the center of gravity of the lighting device 10 to the maximum extent; on the other hand, the control board 125 can be easily accommodated in the cavity. For example: the weight 1233 is a stud-like structure, as shown in fig. 2, the weight 1233 can leave a space for the control board 125. At this time, the control board 125 may be fixed to the base plate 1231 so that the control board 125 receives a force applied thereto by a user when performing a related operation.

Further, the panel 1232 defines a first mounting hole 12321, and the weight 1233 defines a second mounting hole 12331. So configured, after the panel 1232 is assembled with the bottom plate 1231, the second installation hole 12331 and the first installation hole 12321 may be coaxial in the Z direction, so as to install the support rod 122. For example: the support rod 122 is coupled to the weight 1233 through the second mounting hole 12331 and the first mounting hole 12321, and is coupled to the weight 1233 by means of a screw. At this time, the position relationship between the supporting rod 122 and the base 123 is relatively fixed. Of course, a rotating shaft, a hinge, and other similar rotating or moving mechanisms may be disposed between the supporting rod 122 and the base 123, so that the supporting rod 122 can rotate or move relative to the base 123.

In some embodiments, the control board 125 can be provided with a switch element, a photosensitive element, a dimming element, and the like (none labeled in fig. 2), so that a user can realize the functions of turning on or off the lamp body assembly 11, adjusting the light intensity, and the like through the control board 125. Accordingly, a switch button, a dimming knob, and the like (none labeled in fig. 2) may be correspondingly disposed on the panel 1232, so as to facilitate the user to perform corresponding operations. Of course, the switch button and the dimming knob may be of a touch structure. At this time, only the corresponding logo or icon needs to be designed on the panel 1232. For example, the lighting device 10 includes a power switch 126, and the power switch 126 is electrically connected to the control board 125, so that the user can turn on or off the lamp body assembly 11 through the power switch 126, i.e. the power switch 126 is used for conducting the power supply to the lamp body assembly 11; wherein the power source may be an external power source (e.g., mains power) or an internal power source (e.g., battery) of the lighting device 10. Accordingly, a switch button 12322 is correspondingly disposed on the panel 1232, so as to facilitate the corresponding operation of the user.

In other embodiments, the control board 125 may also be provided with a processing module, a transceiver module, a storage module, etc. (none shown in fig. 2) coupled thereto to enable a user to interact with the control board 123 via a portable device such as a remote control, a cell phone, a tablet, a wearable device, etc., to enable the user to remotely control the lighting device 10.

Referring to fig. 3, fig. 3 is an enlarged partial structure view of a region a in the embodiment of fig. 1, wherein the bracket assembly 11 may include a plurality of brackets, which may be frame structures of the lighting device 10, such as the lamp post 121, the supporting rod 122, and the base 123. Wherein, some brackets in the plurality of brackets can be movably connected or fixedly connected.

In an embodiment of the present application, the plurality of brackets includes a set of two adjacent brackets that are movably connected. For example, the plurality of brackets may include a lamp post 121, a supporting rod 122, and a base 123, which are sequentially connected. The two adjacent brackets may be a lamp post 121 and a supporting rod 122 movably connected, and/or the supporting rod 122 and a base 123 movably connected. The lamp body assembly 11 can be disposed on at least one of the lamp post 121, the supporting rod 122 and the base 123 to achieve an illumination function.

The control assembly 13 may include a signal emitting part 131 and a signal receiving part 132, which are correspondingly provided to control the lamp body assembly 11. Wherein one of the signal emitting and receiving parts 131 and 132 is connected to one of the adjacent two brackets of the movable connection, and the other of the signal emitting and receiving parts 131 and 132 is connected to the other of the adjacent two brackets of the movable connection.

For example, when the light pole 121 and the supporting rod 122 are movably connected, the signal transmitter 131 is connected with the supporting rod 122, and the signal receiver 132 is connected with the light pole 121. Of course, in other embodiments, the signal emitting element 131 may be connected to the supporting rod 122, and the signal receiving element 132 may be connected to the light pole 121. When the supporting rod 122 and the base 123 are movably connected, the signal emitting element 131 can be connected with the base 123, and the signal receiving element 132 can be connected with the supporting rod 122; alternatively, the signal emitting element 131 may be connected to the supporting rod 122, and the signal receiving element 132 may be connected to the base 123. It is understood that other connection relationships between the control assembly 13 and the support assembly 12 are also possible, and this is not illustrated in the embodiments of the present application.

Further, the signal receiving part 132 controls the lighting state of the lamp body assembly 11 according to the received signal intensity of the signal emitting part 131. When the adjacent brackets of the movable connection are relatively moved, the distance between the signal emitting part 131 and the signal receiving part 132 is changed.

In the embodiment of the application, the movable connection mode of two adjacent brackets may be a connection mode that enables two adjacent brackets to move relatively, such as a rotary connection mode, a hinge connection mode, a sliding connection mode, and the like. Preferably, when the relative position of two adjacent brackets is shifted, the distance between the signal emitting element 131 and the signal receiving element 132 respectively connected to the two adjacent brackets is changed, so that the signal receiving element 132 can receive the signal emitted by the signal emitting element 131, or so that the signal receiving element 132 can receive part of the signal emitted by the signal emitting element 131, or so that the signal receiving element 132 cannot receive the signal emitted by the signal emitting element 131. Specifically, the signal emitting member 131 may emit a signal such as a magnetic field signal, an optical signal, or the like.

For example, when the spacing between the signal emitting part 131 and the signal receiving part 132 is relatively short, the signal receiving part 131 may receive a strong signal strength. When the distance between the signal emitting part 131 and the signal receiving part 132 is relatively long, the signal receiving part 131 receives a weak signal strength or receives no signal.

The signal receiving part 132 may control the lighting state of the lamp body assembly 11 according to the received intensity of the signal emitted from the signal emitting part 131. Wherein, the signal emitting element 131 is spaced apart from the signal receiving element 132 to facilitate the emission and reception of signals. Further, the signal receiving part 132 may be used to sense a position change of the signal emitting part 131 and perform a corresponding control state according to different positions of the signal emitting part 131.

In some embodiments, the signal receiving part 132 may control the lighting state of the lamp body assembly 11 based on the received signal strength, and the lighting state may include a lamp brightness value and a lamp brightness level. For example, the brightness state includes a lamp brightness level, wherein the lamp brightness level includes a first brightness level, a second brightness level, a third brightness level, and the like. The first brightness grade is the grade when the lamp body is brighter, the third brightness grade is the grade when the lamp body is darker, and the lamp body brightness of the second brightness grade is between the first brightness grade and the third brightness grade.

Further, when the distance between the signal receiving part 132 and the signal emitting part 131 is short, the intensity of the signal received by the signal receiving part 132 is strong, and the light of the first lamp body 11 maintains the first brightness level. When the signal emitting part 131 rotates to increase the distance from the signal receiving part 132 to a certain extent, the intensity of the signal received by the signal receiving part 132 decreases, and the light of the first lamp body 11 is switched from the first brightness level to the second brightness level. When the signal emitting part 131 continues to rotate until the distance between the signal receiving part 132 increases to a larger value, the intensity of the signal received by the signal receiving part 132 is further reduced or no signal is received, and the light of the first lamp body 11 is switched from the second brightness level to the third brightness level. It is understood that the brightness of the lamp body assembly 11 may be continuously changed or may be changed in a jumping manner during the rotation of the signal emitting member 131, and the embodiment of the present invention is not limited in this respect.

The lighting device that this application embodiment provided, through the bracket component that sets up swing joint to connect control assembly in the bracket component, with when relative movement takes place for the bracket component, the interval between signal emission spare and the signal receiving spare in the control assembly changes, and then control lamp body component's bright lamp state, promote the user and use experience.

Further, the bracket assembly 12 may further include a connector 124, the connector 124 being used to connect two adjacent brackets, wherein at least one of the two adjacent brackets in a group is movable relative to the connector 124.

The stand assembly 12 includes a lamp post 121, a supporting rod 122 and a base 123 connected in sequence. The lamp post 121 and the supporting rod 122 may be connected by a connector 124, and/or the supporting rod 122 and the base 123 may be connected by a connector 124. Further, the connecting member 124 may be fixedly connected or movably connected.

In the embodiment of the present application, the light pole 121 and the supporting rod 122 may be movably connected by a connecting member 124, and the light pole 121 and/or the supporting rod 122 can move relative to the connecting member 124.

Specifically, the stand assembly 12 may include a first stand, which may be a light pole 121, and a second stand, which may be a support pole 122. Further, the connecting member 124 includes a first connecting member 1241, and the first bracket and the second bracket are movably connected by the first connecting member 1241. Of course, in other embodiments, the first bracket may support the rod 122, and the second bracket may be the lamp post 121, which is not particularly limited in this embodiment of the present application.

Wherein the signal emitting part 131 is connected to one of the first and second brackets, and the signal receiving part 132 is connected to the other of the first and second brackets. When the first bracket and the second bracket move relatively, the distance between the signal emitting part 131 and the signal receiving part 132 changes, and thus the lighting state of the lamp body assembly 11 is controlled. Preferably, the signal receiving part 132 is disposed on the first bracket, i.e., the lamp post 121, and the signal emitting part 131 is disposed on the second bracket, i.e., the supporting rod 122. The signal receiving part 132 is hidden in the lamp post 121, and the signal emitting part 131 is arranged at the side part of the supporting rod 122, so that the appearance consistency of the lighting device 10 can be ensured; on the other hand, when the first and second brackets are relatively moved, the distance between the signal emitting element 131 and the signal receiving element 132 may be changed.

It should be noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

As shown in fig. 3, the first connecting member 1241 may include a rotating shaft which is connected to the first bracket and the second bracket, respectively, and the first bracket and/or the second bracket can rotate around the axis of the rotating shaft. In other words, at least one of the first support and the second support can rotate in the XY plane through the rotating shaft, so that the relative positions of the first support and the second support can be changed, and further, the change of the distance between the signal receiving part and the signal emitting part is realized.

The signal emitting piece and the signal receiving piece are located on the side of the axis of the rotating shaft, so that when the first support and the second support rotate around the rotating shaft, the distance between the signal emitting piece and the signal receiving piece can be changed.

Of course, in other embodiments, referring to fig. 4, fig. 4 is a partial structural schematic view of a bracket assembly 12 according to other embodiments of the present disclosure. It should be noted that the bracket assembly 12 is illustrated in fig. 4, primarily to implicitly illustrate one possible configuration of the first connector.

The first connector 1241 may include a hinge, and the hinge is connected to the first bracket and the second bracket, respectively, and the first bracket and the second bracket can move relatively through the hinge. In other words, at least one of the first support and the second support can move in the space where XYZ is located through the hinge, so that the relative position of the first support and the second support can be changed, and further, the change of the distance between the signal receiving part and the signal emitting part is realized.

In other embodiments, referring to fig. 5, fig. 5 is a schematic cross-sectional view of a portion of a bracket assembly 12 according to other embodiments of the present disclosure. It should be noted that the bracket assembly 12 is illustrated in fig. 5, primarily to implicitly illustrate one possible configuration of the first connector.

The first connecting member 1241 may include a sliding slot 12411 and a sliding block 12412, the sliding slot 12411 may be disposed on one side of the lamp post 121 close to the supporting rod 122, and the sliding block 12412 may be disposed on one side of the supporting rod 122 close to the lamp post 121. The first and second brackets can move relative to each other via the slide groove 12411 and the slider 12412. In other words, at least one of the first bracket and the second bracket can move in the XY plane through the cooperation of the sliding slot 12411 and the sliding block 12412, so that the relative positions of the first bracket and the second bracket can be changed, and the change of the distance between the signal receiving part and the signal emitting part is realized.

It is understood that the sliding slot 12411 can also be disposed on the side of the supporting rod 122 close to the lamp post 121, and the sliding block 12412 can also be disposed on the side of the lamp post 121 close to the supporting rod 122. That is, the sliding slot 12411 is provided on one of the first bracket and the second bracket, and the sliding block 12412 is provided on the other of the first bracket and the second bracket, so that the sliding slot 12411 and the sliding block 12412 cooperate to enable the first bracket and the second bracket to move relatively.

In some embodiments, the signal emitter 131 may include a magnet, which may be a permanent magnet. Generally, a magnet forms a spherical magnetic field in space, and the magnetic field strength of the spherical magnetic field gradually weakens in a direction away from the magnet. Further, a magnet is provided on one of the adjacent two brackets of the movable connection, and a signal receiving member 132 is provided on the other of the adjacent two brackets of the movable connection. Taking the example of the first bracket and the second bracket movably connected, the signal receiving part 132 is disposed on the first bracket, and the magnet is disposed on the second bracket. When the first bracket and the second bracket are relatively moved, the distance between the magnet and the signal receiving part 132 can be changed, so that the signal receiving part 132 can receive signals with different magnetic field strengths. Wherein the magnet is used for emitting a magnetic field strength signal, the signal receiving part 132 is a device that can perform different actions according to different magnetic field strengths, for example, the signal receiving part 132 can be a hall switch, a reed switch, etc.

It can be understood that when the magnetic field intensity of the magnet acting on the hall switch is greater than or equal to the magnetic field intensity threshold value, that is, the magnet is closer to the hall switch, the hall switch generates an induced current, and the induced current can be converted into a control signal to enable the lamp body to be in a conducting state. When the magnet is far away from the Hall switch, the magnetic field intensity acting on the Hall switch is lower than the threshold value of the magnetic field intensity, the trigger inside the Hall switch is turned, the level state output by the Hall switch is also turned along with the turning, and the lamp body is in a disconnected state at the moment. When the magnetic field intensity of the magnet acting on the magnetic reed switch is larger than or equal to the magnetic field intensity threshold value, namely the distance between the magnet and the magnetic reed switch is short, reeds of the magnetic reed switch are contacted with each other, so that the lamp body is in a conducting state. When the magnet is far away from the magnetic reed switch, so that the magnetic field intensity acting on the magnetic reed switch is lower than the magnetic field intensity threshold value, the elastic sheets of the magnetic reed switch are separated from each other, and the lamp body is in an off state.

Of course, in other embodiments, the signal emitting member 131 may include an optical signal emitter, which may be specifically a laser emitter, an infrared emitter, and the like. Generally, light signal emitters may be incorporated into the bracket assembly 12 to enhance the uniformity of the appearance of the lighting device 10. The signal receiving part 132 may include an optical signal receiver for receiving an optical signal emitted from the optical signal emitter. The optical signal receiver may be a laser receiver, an infrared light receiver, or the like.

Taking the movable connection of the first bracket and the second bracket as an example, the optical signal receiver is arranged on the first bracket, and the optical signal transmitter is arranged on the second bracket. It is understood that when the first support and the second support are relatively moved, the optical signal transmitter and the optical signal receiver may be disposed oppositely or in a staggered manner. When the optical signal transmitter is opposite to the optical signal receiver, the optical signal transmitted by the optical signal transmitter can basically completely act on the optical signal receiver, i.e. the optical signal that can be received by the optical signal receiver is stronger. When the relative state of the optical signal transmitter and the optical signal receiver changes into the dislocation state, the optical signal transmitted by the optical signal transmitter cannot necessarily act on the optical signal receiver, that is, the optical signal that can be received by the optical signal receiver is weakened.

Referring to fig. 6, fig. 6 is a schematic structural diagram of an illumination device 10 according to another embodiment of the present application. It should be noted that fig. 6 shows the lighting device 10, mainly for the purpose of implicitly illustrating one possible structure of the lighting device 10. The lamp body assembly 11 includes a first lamp body 111 and a second lamp body 112 connected in parallel. For example, the first bracket 121 is a lamp post, and the second bracket 122 is a support rod.

Specifically, the second lamp body 14 is connected in parallel to the first lamp body 11 by a wire, that is, the second lamp body 14 is connected in parallel to the first lamp body 11 by a wire, so that the signal receiving part 132 can control the lighting state of the first and second lamp bodies 111 and 112 according to the intensity of the received signal emitted from the signal emitting part 131. Due to the parallel relationship between the second lamp body 112 and the first lamp body 111, when one of the first lamp body 111 and the second lamp body 112 is turned on, the other is turned off.

Referring to fig. 7, fig. 7 is a schematic view illustrating a usage state of the lighting device 10 in the embodiment of fig. 6. In the embodiment shown in fig. 6, the signal emitting element 131 and the signal receiving element 132 are located on the same side of the second bracket 122, and the distance between the signal emitting element 131 and the signal receiving element 132 is the shortest, that is, the signal receiving element 132 can receive the strongest signal emitted by the signal emitting element 131. In this state, the signal receiving part 132 controls the first lamp body 111 to be lighted, i.e., the light emitting direction of the lighting device 10 is the F1 direction as shown in fig. 6. When the first support 121 is moved from the position shown in fig. 6 to the position shown in fig. 7, the signal emitting element 131 and the signal receiving element 132 are located on opposite sides of the second support 122, and the distance between the signal emitting element 131 and the signal receiving element 132 is the farthest, i.e. the signal receiving element 132 can receive a signal emitted by the signal emitting element 131 with a weak strength. In this state, the signal receiving part 132 controls the second lamp body 112 to be lighted, i.e., the light emitting direction of the lighting device 10 is the F2 direction as shown in fig. 7.
