The lighting area of ​​a single table lamp is often limited, and it can only illuminate part of the area, which easily creates a sense of claustrophobia. In order to ensure that the user has a larger field of vision, the surrounding environment needs to be illuminated. Users usually turn on the indoor lights and then turn on the table lamp at the same time to make up for the problem of insufficient light source in the desktop environment. Therefore, the existing table lamp structure often has the problem that a single table lamp cannot meet the lighting needs of users, and it needs to be used in combination with indoor lights, which causes a certain degree of energy waste and limits the limitations of the use of table lamps.

[0062] Example:

[0063] See also Figures 1 to 9 In the preferred embodiment of the utility model, the combined lamp panel includes a first lamp panel 3 and a second lamp panel 4, wherein the first lamp panel 3 has a first light-emitting surface, and the second lamp panel 4 has a second light-emitting surface. A connecting member 5 is provided between the first lamp panel 3 and the second lamp panel 4, and the connecting member 5 includes a first fixing portion 509 connected to the first lamp panel 3 and a second fixing portion connected to the second lamp panel 4; and an adjusting portion is provided between the first fixing portion 509 and the second fixing portion, and the adjusting portion is used to drive the first lamp panel 3 and the second lamp panel 4 to rotate relative to each other, so as to realize the first light-emitting surface and the second light-emitting surface are arranged in the same direction or in reverse. At the same time, the first fixing portion 509 includes a first surface and a second surface, the first surface is connected to the second surface, and the first surface and the second surface are in different planes, and a mounting portion is correspondingly provided on the first lamp panel 3, and the mounting portion is arranged to fit with the first surface and the second surface. Optionally, the mounting portion here can be a protruding structure extending out of the main body of the first lamp panel 3, or it can be a notch or notch structure recessed in the main body of the first lamp panel 3.

[0064] Specifically, the present application sets a connector 5 between the two lamp panels, and uses the connector 5 to realize the flipping of the first lamp panel 3 and the second lamp panel 4, and rotates the first lamp panel 3 and the second lamp panel 4 through the adjustment part; so that the two lamp panels are in a state of emitting light away from each other and emitting light in the same direction. When the two lamp panels emit light away from each other, the combined lamp panel forms a spherical light source, which can illuminate the entire surrounding environment and avoid the user from feeling claustrophobic when using the table lamp; when the second lamp panel 4 is flipped to the same side as the first lamp panel 3, the light sources of the two lamp panels emit light in parallel, thereby expanding the illumination range of the table surface and improving the brightness of the table surface. The combined lamp panel structure in the present application realizes the effects of lighting the surrounding area, increasing the lighting area of ​​the desktop, and increasing the brightness of the illuminated area by changing the direction angle of the first lamp panel 3 and the second lamp panel 4. The user's daily reading and life use needs are met through the combination of lamp panels, and the sense of claustrophobia is not caused, which improves the applicable scenarios of the lamp. At the same time, the present application sets the first fixing part 509 to the first surface and the second surface which are not in the same plane. The first surface and the second surface can limit the installation part of the first lamp panel 3 to ensure the connection stability between the first lamp panel and the first fixing part 509.

[0065] Furthermore, the adjustment part includes a first connection part and a second connection part, and the first connection part and the second connection part are arranged to rotate with each other, and there is rotation damping between the first connection part and the second connection part, and the first connection part is connected to the first fixing part 509, and the second connection part is connected to the second fixing part. Specifically, the present application uses the rotation damping between the first connection part and the second connection part to enable the first fixing part 509 and the second fixing part to stay at a set angle when they rotate relative to each other, thereby allowing the first lamp panel 3 and the second lamp panel 4 to remain at the set angle, so as to achieve stable lighting of the combined lamp panel in different states.

[0066] Furthermore, the first connection part of the present application has a rotating rod extending toward the second connection part, the rotating rod has at least one abutment part extending radially, and the rotating rod is inserted into the second connection part, the inner peripheral side wall of the second connection part has two notches matching the abutment part, and the abutment part can match the two notches respectively. Although the rotation damping between the first connection part and the second connection part can make the first lamp panel 3 and the second lamp panel 4 stay at the set angle, the fixing method of the rotation damping is not firm. In order to ensure that the two lamp panels can be locked at the set angle, the present application sets the abutment part and the notch accordingly. By matching the abutment part with different notches, the first connection part and the second connection part can be locked at different angles, thereby realizing the stable use of the foldable double-sided light-emitting lamp panel eye protection lamp in different states.

[0067] Further preferably, the notch includes a first notch and a second notch, and the first notch is the same width as the abutment portion, and the second notch is larger than the abutment portion, so that the abutment portion is movably arranged in the second notch. When the first lamp panel 3 and the second lamp panel 4 are stacked, the two lamp panels form a vertically opposite light source, and the two do not need to be movable, so the abutment portion and the first notch are exactly matched to lock the two lamp panels into a stable state, maintain the overall beauty of the foldable double-sided light panel eye protection lamp, and ensure the uniformity of the spherical light source formed to avoid the situation where the two light sources deviate and cause the lighting space to be partially bright and partially dark. When the light sources of the first lamp panel 3 and the second lamp panel 4 are facing downward at the same time, there is a need to increase the desktop lighting area and enhance the brightness of some areas, so the first lamp panel 3 and the second lamp panel 4 need to have a certain activity space, and the lamp panels are restricted by rotation damping to facilitate the adjustment of the lighting method.

[0068] Further, as an optional embodiment of the utility model, the first connection part in the present application includes a second connection part connected to the first lamp panel 3, a first connection part connected to the second lamp panel 4, and a rotation axis, the first connection part and the second connection part are rotatably sleeved on the rotation axis, and the end surface of the first connection part and / or the second connection part connected to the rotation axis has rotation damping. Specifically, the present application can connect the first lamp panel 3 and the second lamp panel 4 respectively through the first connection part and the second connection part, and then pass the rotation axis between the two, and use the rotation axis and the rotation damping of the two to achieve the first lamp panel 3 and the second lamp panel 4 staying at a set angle.

[0069] It is worth noting that the function of the first connecting part and the second connecting part in the present application is to enable the first lamp panel 3 and the second lamp panel 4 to be misaligned through the first connecting part and the second connecting part even when they are stacked on each other, so that the two can rotate relative to the rotation axis, so as to avoid the rotation axis being stuck between the first lamp panel 3 and the second lamp panel 4, failing to form a complete stack, resulting in the problem of uneven spherical light source.

[0070] Correspondingly, one end of the rotating shaft in the present application extends into the first connecting part, and the end surface of the first connecting part and the rotating shaft is provided with at least one abutment portion, and the outer peripheral wall surface of the rotating shaft has at least two notches matching the abutment portion. Similarly, the first lamp panel 3 and the second lamp panel 4 cannot be completely locked by rotation damping alone. The present application corresponds to setting an abutment portion and a notch on the connecting wall surface of the first connecting part and the rotating shaft, and the abutment portion is matched with the notch respectively to achieve locking of the first connecting part and the second connecting part at different angles.

[0071] Optionally, when the first connection portion and the rotation axis can be matched and locked at different angles, the second connection portion and the rotation axis are in a relatively fixed state to achieve locking of the first lamp panel 3 and the second lamp panel 4 at different angles.

[0072] Preferably, the notch here includes a first notch and a second notch, and the first notch is the same width as the abutment portion, and the second notch is larger than the abutment portion, so that the abutment portion is movably arranged in the second notch. When the first lamp panel 3 and the second lamp panel 4 are stacked, the abutment portion matches the first notch to lock the two lamp panels with each other to form a spherical light source with good uniformity; when the light-emitting surfaces of the first lamp panel 3 and the second lamp panel 4 are on the same side, the first lamp panel 3 and the second lamp panel 4 are arranged in a straight state or at a certain angle, and the movable arrangement of the abutment portion in the second notch enables the first lamp panel 3 and the second lamp panel 4 to be at a certain angle, thereby converging the light source to light up a part of the area, so as to increase the applicability of the foldable double-sided light panel eye protection lamp.

[0073] Further, as a preferred embodiment of the utility model, the first connection part in the present application includes a first fixing part 509, and the second connection part includes a second fixing part. The first fixing part and the second fixing part are arranged side by side, and the first fixing part 509 is embedded in the second lamp panel 4, and the second fixing part is embedded in the first lamp panel 3. The end faces of the first fixing part 509 and the second fixing part are in the same plane as the axis of the rotating shaft. In order to prevent the first connection member 5 from protruding too much from the first lamp panel 3 and the second lamp panel 4, resulting in a large gap between the first lamp panel 3 and the second lamp panel 4 when they are in a straight state, the present application partially embeds the first fixing part 509 and the second fixing part into the first lamp panel 3 and the second lamp panel 4. At this time, the first fixing part 509 and the second fixing part will not affect the stacking of the first lamp panel 3 and the second lamp panel 4, ensuring the stacking stability of the two while forming a spherical light source with good lighting uniformity; at the same time, the connection gap between the first lamp panel 3 and the second lamp panel 4 is made as small as possible, so that the first lamp panel 3 and the second lamp panel 4 completely light up the area below. The end faces of the first fixing portion 509 and the second fixing portion connected to each other and the axis of the rotating shaft are located in the same plane, so that when the first lamp panel 3 and the second lamp panel 4 are in a stacked state, the first connecting portion and the second connecting portion will not pull the first lamp panel 3 and the second lamp panel 4 accordingly, so that the two are in a stable and straight state. Of course, in the actual production process, when there is a slight deviation between the end faces of the first fixing portion 509 and the second fixing portion connected to the axis of the rotating shaft in the plane, it is a manufacturing error and should also be covered within the protection scope of this application.

[0074] Further preferably, in the present application, the first lamp panel 3 and the second lamp panel 4 are circular, and the first fixing portion 509 and the second fixing portion are respectively connected to the side wall surfaces of the first lamp panel 3 and the second lamp panel 4, and the adjustment portion includes a rotating shaft, and the axial length of the rotating shaft is 10mm~30mm. The circular lamp panel structure has a relatively large light-emitting area, which is suitable for conventional lighting and learning use. At the same time, since the first lamp panel 3 and the second lamp panel 4 of the present application are both circular structures, the connection surface between the two lamp panels is relatively small. In order to ensure that the first connecting member 5 stably connects the first lamp panel 3 and the second lamp panel 4, and to avoid the adjustment portion protruding too much from the end faces of the two lamp panels, the length of the rotating shaft inside the adjustment portion in the present application is between 10mm~30mm, so as to take into account both connection stability and aesthetics.

[0075] Furthermore, the first connection part and the second connection part in the present application are arranged side by side, and a rotation axis is passed through the first connection part and the second connection part, and the first connection part and / or the second connection part are arranged to rotate with the rotation axis. Specifically, when the first connection part and / or the second connection part can rotate relative to the rotation axis, the first lamp panel 3 and the second lamp panel 4 can rotate relative to each other. Specifically, the side-by-side arrangement of the first connection part and the second connection part here means that the two are in a state of being adjacent to each other in space, and when the rotation axis is used as a calibration object, the first connection part and the second connection part are simultaneously passed through the rotation axis.

[0076] Further, as an optional embodiment of the present invention, the first connection part in the present application includes a first connection ring 501, and the second connection part includes a second connection ring 502. The first connection ring 501 and the second connection ring 502 are coaxially arranged, and a rotation axis is provided between the first connection ring 501 and the second connection ring 502. When the first connection part and the second connection part are used to realize the relative rotation of the first lamp panel 3 and the second lamp panel 4, the present application sets the first connection ring 501 and the second connection ring 502, and sets the rotation axis to constrain the two, so that the first connection ring 501 and the second connection ring 502 can both rotate around the rotation axis, thereby realizing the relative rotation of the first lamp panel 3 and the second lamp panel 4.

[0077] Further preferably, the rotating shaft comprises a first rotating part 503 and a second rotating part 504 arranged along the axial direction of the first connecting ring 501, the first rotating part 503 is coaxially sleeved in the second connecting ring 502, the second rotating part 504 is coaxially sleeved in the first connecting ring 501, and the first rotating part 503 and the second rotating part 504 are connected by screws. When the conventional first connecting ring 501, the second connecting ring 502 and the rotating shaft structure are adopted, the first connecting ring 501 and the second connecting ring 502 cannot be relatively locked, and both can rotate relative to the rotating shaft, so that the lamp panel structure connected with the first fixing part 509 and the second fixing part cannot be locked to a set position, and the two lamp panels cannot be combined to form multiple light-emitting forms in the same direction or opposite directions. Therefore, the present application sets the rotating shaft in the form of a combination of the first rotating part 503 and the second rotating part 504, so that the first rotating part 503 and the second rotating part 504 can be designed separately, and the two rotating parts cooperate with the first connecting ring 501 and the second connecting ring 502 respectively to achieve the locking of the first lamp panel 3 and the second lamp panel 4 at the set position and angle.

[0078] Furthermore, in the present application, a damping surface 505 is radially provided inside the first connecting ring 501, the first rotating part 503 and the second rotating part 504 are respectively provided on both sides of the damping surface 505, and a first through hole for screws to pass through is provided on the damping surface 505; the second rotating part 504 is provided with a fitting surface 506 on the side facing the damping surface 505, the fitting surface 506 is in contact with the damping surface 505, and a second through hole for screws to pass through is provided on the fitting surface 506. The structure in which the damping surface 505 and the fitting surface 506 are in close contact with each other enables relative friction to be generated between the second rotating part 504 and the first connecting ring 501 when the first connecting ring 501 and the second connecting ring 502 rotate relative to each other, thereby enabling the first connecting ring 501 and the second connecting ring 502 to stop at any angle, so that the two lamp panels connected to the first fixing part 509 and the second fixing part can be fixed at any angle. At the same time, the first rotating part 503 of the present application is provided with a threaded hole, and the screw passes through the first through hole and the second through hole, and the first rotating part 503 and the second rotating part 504 are connected as a whole. The threaded connection form makes the damping between the damping surface 505 and the fitting surface 506 adjustable, so that the rotating shaft can adapt to lamp panels of different sizes, ensuring that the lamp panel can stay at any position, while increasing the convenience of adjusting the two lamp panels, so as to avoid the problem of difficulty in adjustment caused by excessive damping.

[0079] Further, as a preferred embodiment of the utility model, the first rotating part 503 in the present application includes at least two planes along the circumferential direction, and the inner circumferential wall surface of the second connecting ring 502 and the outer circumferential wall surface of the first rotating part 503 are mutually engaged; the present application requires that the first connecting ring 501 and the second connecting ring 502 can rotate relative to each other, and at the same time, the two can be stopped at any angle, wherein the first connecting ring 501 and the second rotating part 504 realize damped rotation through the cooperation of the damping surface 505 and the fitting surface 506, if the second connecting ring 502 and the first rotating part 503 can rotate arbitrarily, the first connecting ring 501 and the second connecting ring 502 cannot stop at any angle. Based on this, the present application sets at least two planar structures on the outer circumference of the first rotating part 503, and the planes are offset against the planes on the inner circumference of the second connecting ring 502, so as to prevent the first rotating part 503 and the second connecting ring 502 from rotating relative to each other at will. In addition, the inner wall surface of the first connecting ring 501 is provided with at least one limiting strip 507, and the outer wall surface of the second rotating part 504 is provided with at least two notches matching the limiting strip 507. Although the damping rotation form can keep the first connecting ring 501 and the second connecting ring 502 at different angles, its stability is poor. During the long-term use of the lamp panel, it will cause relative wear between the damping surface 505 and the fitting surface 506, and eventually make the lamp panel unable to be locked at the set angle. Based on this, the present application corresponds to setting a limiting strip 507 on the inner wall surface of the first connecting ring 501, and correspondingly setting a notch on the outer wall surface of the second rotating part 504. When the limiting strip 507 is stuck in the notch, the first connecting ring 501 and the second connecting ring 502 are relatively locked, thereby fixing the two lamp panels at different angles. When the light-emitting form of the lamp panel needs to be changed, the first connecting ring 501 and the second connecting ring 502 rotate relative to each other, and the limiting strip 507 is disengaged from one of the notches and then falls into the other notch, so as to lock the first connecting ring 501 and the second connecting ring 502 at another angle, thereby realizing the locking of the first lamp panel 3 and the second lamp panel 4 at different angles. Furthermore, the two notches are distributed at two positions of the same radial direction of the second rotating part 504, so that a single limiting strip 507 can match the two notches respectively, thereby realizing the locking of the two connecting rings at different angles.

[0080] Optionally, in addition to the above-mentioned matching form of a single limiting strip 507 and two notches, a matching form of multiple limiting strips 507 and multiple notches can also be used, thereby achieving locking of the two lamp panels at different angles.

[0081] Further, as an optional embodiment of the utility model, the outer peripheral wall surface of the second rotating part 504 in the present application has a first notch and a second notch, and the limit strip 507 can match the first notch and the second notch respectively. Moreover, the opening width of the first notch is the same as the width of the limit strip 507, and the opening width of the second notch is not less than the width of the limit strip 507. When the direction and angle of the two lamp panels are limited by the rotating shaft, when the two lamp panels are stacked on each other, the two lamp panels are in a stable position. At this time, the two lamp panels do not need to have a large activity space. The first lamp panel 3 and the second lamp panel 4 are locked by the limitation of the first notch and the limit strip 507, so as to facilitate the use of the lamp panels at this angle and facilitate the collection and placement of the lamp panels. When the first connecting ring 501 and the second connecting ring 502 rotate 180° relative to each other, the two lamp panels change from being stacked on each other to being arranged side by side, and the limit strip 507 falls into the second notch. In actual use, when the two lamp panels are in a straight state, users usually need to adjust the angle of the lamp panel appropriately according to actual use needs, so as to adjust the illuminated area and the brightness of the set position. If the second notch completely locks the limit strip 507, it is not convenient to adjust the angle of the lamp panel. Based on this, the present application appropriately increases the width of the second notch, so that the width of the second notch is greater than the width of the limit strip 507, so that the limit strip 507 can move slightly in the second notch, and the angle of the lamp panel is locked by the cooperation of the damping surface 505 and the fitting surface 506, so as to achieve slight adjustment of the lamp panel in a straight state.

[0082] Further preferably, the second connection part in the present application also includes a third connection ring 508 arranged side by side with the second connection ring 502, the second connection ring 502 and the third connection ring 508 are arranged integrally, and the first connection ring 501 is arranged between the second connection ring 502 and the third connection ring 508. When the first connection ring 501 and the second connection ring 502 are used to rotate relative to each other, the two cannot form a constraint, resulting in the relative rotation of the two being not stable enough. Based on this, the present application sets the third connection ring 508, and the first connection ring 501 is restricted by the second connection ring 502 and the third connection ring 508, so that the first connection ring 501 is set to rotate in a direction to ensure the stable rotation and matching of the first lamp panel 3 and the second lamp panel 4, avoid mutual wear caused by mismatched rotation between the various structural parts of the combined lamp panel, and improve the service life of the combined lamp panel while ensuring the appearance.

[0083] Further preferably, in the present application, the first fixing portion 509 is detachably connected to the second lamp panel 4, and / or the second fixing portion is detachably connected to the first lamp panel 3. The present application needs to be connected to the first lamp panel 3 and the second lamp panel 4 respectively through the first fixing portion 509 and the second fixing portion, so that when the first connecting ring 501 and the second connecting ring 502 rotate relative to each other, the first lamp panel 3 and the second lamp panel 4 rotate accordingly. The detachable connection between the first fixing portion 509 and the second lamp panel 4, and the detachable connection between the second fixing portion and the first lamp panel 3, facilitate the replacement of various structural parts of the combined lamp panel. At the same time, the provision of the first fixing portion 509 and the second fixing portion facilitates the arrangement of the first lamp panel 3 and the second lamp panel 4, and increases the contact area between the lamp panel and the fixing portion, thereby avoiding the problem of stress concentration at the connection portion between the two and ensuring the overall stability of the combined lamp panel.

[0084] Optionally, the first fixing portion 509 in the present application includes a first surface and a second surface, and the first surface and the second surface are arranged perpendicular to each other, and a notch is correspondingly arranged on the first lamp panel 3, and the notch is arranged to fit the first surface and the second surface. The present application sets a matching plane of a "┐" structure at the first fixing portion 509 and the first lamp panel 3, so that there is a horizontal and vertical abutment plane between the first fixing portion 509 and the first lamp panel 3. When the first lamp panel 3 is rotating, the first surface and the second surface can form an abutment to distribute the force at the contact point, avoid stress concentration at the connection between the first lamp panel 3 and the first fixing portion 509, and ensure the reliability of the connection between the two.

[0085] Furthermore, the first fixing portion 509 of the present application is provided with a first connection groove, and the second lamp panel 4 extends toward the first connection groove with a first fixing protrusion, and the first fixing protrusion is embedded in the first connection groove. When the first fixing portion 509 is used to connect with the second lamp panel 4, the present application adopts a protrusion and a groove matching form so that the two are mutually embedded, thereby realizing the connection between the second lamp panel 4 and the first fixing portion 509. Preferably, the structure of the second fixing portion in the present application is the same as that of the first fixing portion 509, and correspondingly, the structure of the first lamp panel 3 is also the same as that of the second lamp panel 4, so that when the first lamp panel 3, the second lamp panel 4 or the connecting member 5 is damaged, the same accessories can be used for replacement.

[0086] Further preferably, the second connecting portion is connected to the side wall of the first lamp panel 3, and a rotating member 6 is further provided on the side of the first lamp panel 3 facing away from the second connecting portion, and the rotating member 6 correspondingly includes a third connecting portion and a fourth connecting portion, and the third connecting portion and the fourth connecting portion are also rotatably arranged, the third connecting portion is connected to the first lamp panel 3, and the fourth connecting portion has a connecting head. The combination lamp panel in the present application also needs to be assembled to the rod or the base 1 to form a table lamp structure. Based on this, the present application correspondingly sets a rotating member 6, and connects to the outside through the matching structure of the third connecting member 5 and the fourth connecting member 5 through the connecting head of the fourth connecting member 5, so as to assemble the combination lamp panel to the table lamp body. The rotatable connection between the third connecting member 5 and the fourth connecting member 5 makes the light-emitting angle of the combination lamp panel adjustable to meet the user's usage requirements.

[0087] Preferably, the third connection part in the present application has the same structure as the first connection part, and the fourth connection part has the same structure as the second connection part. This ensures that the overall angle of the combined lamp panel is adjustable and can be locked at a set angle. Correspondingly, the connector structure of the fourth connection part of the present application is equivalent to the second fixing part of the second connection part, and both are used to connect with other components.

[0088] Further, as a preferred embodiment of the utility model, the first lamp panel 3 and the second lamp panel 4 in the present application have the same structure. Taking the first lamp panel 3 as an example, the first lamp panel 3 includes a first shell and a second shell, and the first shell and the second shell are surrounded to form a receiving cavity, and the light-emitting component is arranged in the receiving cavity.

Preferably, the light-transmitting plate is a rhombus plate, which allows the light emitted by the light-emitting components to be refracted through the rhombus grids of the rhombus plate and spread out for illumination, making the light more uniform, soft and not glaring.

[0091] Correspondingly, in the present application, heat dissipation holes are provided on the circumferential wall surfaces of the first shell and the second shell, and the heat dissipation holes are mainly used for heat dissipation of the light-emitting components inside the first lamp panel 3 to ensure the stable use of the first lamp panel 3.

[0092] Furthermore, based on the combination lamp panel in the present application, the present application also corresponds to an eye protection lamp, which includes a connecting rod 2, one end of which is open, and the connecting rod 2 is detachably connected to the combination lamp panel in the present application, and the connecting head of the fourth connecting part of the present application is inserted into the opening of the connecting rod 2.
