[0036] Certain words are used in the specification and claims to refer to specific components. Those with ordinary knowledge in the field should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but rather use differences in components' functions as the criteria for distinction. The term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".

[0037] The lamp provided by the present invention is suitable for installation on a display screen, bookcase, desk, bedside table, workbench or other device or hardware equipment that requires local lighting. In this embodiment, the lamp is installed on the upper edge of the display screen, see Figures 1 to 4The lamp includes a lamp source 1 and a lamp arm 2. The lamp source 1 includes a first shell 11 and a first connecting member 12. The first shell 11 includes a receiving chamber 111. The first connecting member 12 includes a first end 121 and a second end 122 opposite to each other. The first end 121 is connected to the side wall of the receiving chamber 111, and the second end 122 is located in the receiving chamber 111. The first end 121 and the side wall of the receiving chamber 111 can be fixedly connected by, for example, rivet fastening, screw locking, snap fastening, etc. In this embodiment, the first end 121 and the side wall of the receiving chamber 111 are fixedly fixed by a first screw 6, but the present invention is not limited thereto. The lamp arm 2 includes a second shell 21 and a second connecting member 22. The second connecting member 22 includes a third end 221 and a fourth end 222 opposite to each other. The third end 221 is connected to the second shell 21, and the fourth end 222 extends into the receiving chamber 111, and the fourth end 222 is hinged to the second end 122. The fourth end 222 and the second end 122 are, for example, hinged by a rotating shaft, or mutually clamped or hooked, etc., but the present invention is not limited thereto. The third end 221 and the second shell 21 can be fixedly connected by, for example, rivet fastening, screw locking, snap fastening, etc. In this embodiment, the third end 221 and the second shell 21 are locked and fixed by the second screw 7, but the present invention is not limited thereto. In this way, by the rotation of the first shell 11, the second end 122 is driven to rotate relative to the fourth end 222 around an axis, so that the first shell 11 rotates relative to the second shell 21 to adjust the illumination range of the light source 1 relative to the lamp arm 2, wherein the first shell 11 rotates around the axis, in other words, the axis passes through the center of the first shell 11, wherein the center of the first shell 11 refers to a point located in the accommodating cavity 111, and when the first shell 11 rotates relative to the second shell 21, the distance between any position on the first shell 11 and the point remains unchanged.

[0038] In a preferred embodiment, please refer to Figure 3 and Figure 4 The lamp also includes a rotating shaft 3, and the fourth end 222 of the second connecting member 22 and the second end 122 of the first connecting member 12 are hinged through the rotating shaft 3, that is, the axis around which the first housing 11 rotates is the axis of the rotating shaft 3. Preferably, the rotating shaft 3 includes a fifth end and a sixth end opposite to each other, and the fifth end and the sixth end are located on the same straight line, that is, the rotating shaft 3 is a linear rotating shaft. In other embodiments, the rotating shaft 3 can also be in other shapes, such as a "Z" shape, etc., and the present invention is not limited thereto. In addition, the radial dimension of the rotating shaft 3 can be designed to be smaller (for example, the diameter of the rotating shaft 3 is less than 5 mm), so that the rotating shaft 3 will not interfere with other components (such as light-emitting components, etc.) in the first housing 11. In this way, since the rotating shaft 3 is located in the accommodating cavity 111 of the first housing 11, its rotating structure cannot be directly seen from the outside of the lamp, making the appearance of the lamp more beautiful.

[0039] In a preferred embodiment, please refer to Figure 2 and Figure 3 , the shaft member 3 is fixedly connected to one of the second end 122 of the first connecting member 12 or the fourth end 222 of the second connecting member 22, and the shaft member 3 is rotatably connected to the other of the two, wherein the shaft member 3 is fixedly connected to one of the two by, for example, rivet fastening, screw locking, snap-on clamping, etc. In this embodiment, the shaft member 3 is fastened to one of the two by rivet 4, but the present invention is not limited thereto. In a preferred embodiment, the fastening direction y of the rivet 4 is perpendicular to the extension direction x of the axis of the shaft member 3. Furthermore, there are at least two rivets 4, and the at least two rivets 4 are arranged along the extension direction x of the axis of the shaft member 3, so that the shaft member 3 is more firmly locked and fixed to one of the second end 122 or the fourth end 222.

[0040] In one embodiment, see Figure 3 and Figure 4 , the other of the second end 122 or the fourth end 222 is wound around the shaft wall of the shaft member 3, so that the shaft member 3 can rotate in the annular cavity formed by the bending of the other of the two, that is, the shaft member 3 is rotatably connected to the other of the two. In another embodiment, please refer to Figure 5 The other of the second end 122 or the fourth end 222 is provided with an opening 223, through which a screw 51 passes, and is fixed to the end of the shaft member 3 and the nut 52 along the extension direction x of the axis of the shaft member 3, so that the shaft member 3 is rotatably connected to the other of the two (the rest of the parts are omitted in the figure). Alternatively, please refer to Figure 6 The other of the second end 122 or the fourth end 222 may also be a sleeve, which is sleeved on the end of the shaft member 3 so that the shaft member 3 can be rotatably connected to the other of the two.

[0041] In a preferred embodiment, please refer to Figures 2 to 4A slot 112 is provided on the side wall of the accommodating cavity 111, and the fourth end 222 passes through the slot 112 to enter the accommodating cavity 111 and is hinged with the second end 122. Since the second connecting member 22 is fixedly connected to the second shell 21, when the first shell 11 rotates relative to the second shell 21, the first shell 11 also rotates relative to the second connecting member 22. Therefore, the slot 112 provides a space for the actuation process of the first shell 11. The slot 112 includes a first edge 1121 and a second edge 1122, and the second connecting member 22 includes a first surface 223 and a second surface 224. When the second connecting member 22 moves to the first position in the slot 112, the first surface 223 abuts against the first edge 1121; when the second connecting member 22 moves to the second position in the slot 112, the second surface 224 abuts against the second edge 1122. That is, when the first shell 11 rotates relative to the second connecting member 22, the second connecting member 22 will follow the rotation direction of the first shell 11 and move accordingly in the slot 112 within the range from the first position to the second position. Please refer to Figures 2 to 4 When the first surface 223 abuts against the first edge 1121, or when the second surface 224 abuts against the second edge 1122, an abnormal sound will be generated due to the collision between the second connecting member 22 and the edge of the slot 112. In order to reduce the abnormal sound, in this embodiment, a sound-absorbing gasket 23 is provided at least on the first surface 223 and the second surface 224 of the second connecting member 22 to improve the user experience of the lamp. In other words, the position where the sound-absorbing gasket 23 is set must at least meet the following conditions: the sound-absorbing gasket 23 can cover all surfaces of the second connecting member 22 that may abut against the edges of the slot 112, so as to effectively reduce the abnormal sound while ensuring that the area of ​​the sound-absorbing gasket 23 is small and the material cost is saved. In another embodiment, the sound-absorbing gasket 23 can also be provided at the first edge 1121 and the second edge 1122 of the slot 112, but the present invention is not limited thereto.

[0042] In a preferred embodiment, the second connecting member 22 includes a first section and a second section, the third end 221 of the second connecting member 22 is located in the first section, and the fourth end 222 of the second connecting member 22 is located in the second section. The first section and the second section are connected (for example, integrally formed), and there is an angle between the first section and the second section. In other words, the shape of the second connecting member 22 has a turning point. In this embodiment, the second connecting member 22 is "L" shaped. In other embodiments, the second connecting member 22 can also be other shapes, and the present invention is not limited thereto. Preferably, the turning point is located in the accommodating cavity 111, that is, the first section is fixedly connected to the housing 21 through the third end 221, and is penetrated in the slot 112, and further extends into the accommodating cavity 111, and the second section is connected to the first section located in the accommodating cavity 111 and extends to the second end 122, so that the fourth end 222 is hinged to the second end 122.

[0043] In a preferred embodiment, please refer to Figure 2 , the side wall of the accommodating cavity 111 includes an arc-shaped wall, the bending direction of the arc-shaped wall is toward the axis around which the first housing 11 rotates and has a curvature radius r, and the distance d between the first end 121 and the second end 122 of the first connecting member 12 is less than or equal to the curvature radius r of the arc-shaped wall, which means that the first connecting member 12 is completely accommodated in the accommodating cavity 111. In other words, the overall shape of the first connecting member 12 is not necessarily a straight plate, and it can also be designed as any other shape (for example, the first connecting member 12 is a bent "L" shape, "Z" shape, etc.), and the present invention is not limited thereto. For the first connecting member 12 of any shape, according to the rotation structure provided by the present invention, it is necessary to ensure that the maximum distance d between the first end 121 and the second end 122 is less than or equal to the curvature radius r of the side wall of the accommodating cavity 111, so that the first connecting member 12 is completely accommodated in the accommodating cavity 111. In this way, the first connecting member 12 cannot be observed from the appearance of the lamp, making the lamp more beautiful. In one embodiment, the side wall of the accommodating cavity 111 further includes a mounting wall, that is, the side wall of the accommodating cavity 111 is not entirely an arc-shaped wall. The first end 121 of the first connecting member 12 is connected to the mounting wall, wherein the mounting wall is a straight wall, so that the first end 121 is more firmly connected to the side wall of the accommodating cavity 111, and the minimum distance between the mounting wall and the axis is less than or equal to the radius of curvature r of the arc-shaped wall. Preferably, in order to facilitate the first end 121 and the mounting wall to be locked and fixed by the first screw 6, the wall thickness of the mounting wall can be greater than or equal to the wall thickness of the arc-shaped wall, and the increasing direction of the wall thickness of the mounting wall extends toward the position of the axis, so when the entire first connecting member 12 is completely accommodated in the accommodating cavity 111, the distance d between the first end 121 and the second end 122 must be less than or equal to the radius of curvature r of the arc-shaped wall. It should also be noted that the distance d between the first end 121 and the second end 122 is less than or equal to the curvature radius r of the arc wall, which does not mean that the distance d between the first end 121 and the second end 122 is infinitely small. The distance d must at least ensure that: the first connecting member 12 can support the first shell 11 to rotate relative to the second shell 21, and other components (such as light-emitting components, etc.) in the accommodating cavity 111 have sufficient accommodating space.

[0044] Furthermore, the light source 1 includes a light-emitting component, which is, for example, a lamp tube (not shown) installed in the accommodating cavity 111, and the configuration direction of the light-emitting component is parallel to the axis around which the first shell 11 rotates. It can be understood that the light-emitting component has a light-emitting surface, and the first shell 11 rotates relative to the second shell 21, so that the first shell 11 drives the light-emitting surface to rotate relative to the second shell 21, so as to adjust the direction of the light-emitting surface of the light-emitting component, and then adjust the illumination range of the light source 1. Because the axis passes through the center of the first shell 11, when the user holds the first shell 11 and rotates it, the torque that the hand needs to apply to the first shell 11 is easy to control, so as to achieve the purpose of a good feel of rotating the light source 1, and the light-emitting surface of the light-emitting component rotates around the axis to make its actuation trajectory more regular, which is conducive to adjusting the direction of the light-emitting surface, and can reduce the impact of the rotation on the angle of reflected light and glare on the display screen. It should be noted that in order to ensure that the structural strength of the lamp is high enough to support the reliable operation of the light source 1, the first connecting member 12 and / or the second connecting member 22 are made of a material with strong rigidity, and the thickness thereof is, for example, in the range of 0.5 mm to 3 mm, but the present invention is not limited thereto.

[0045] Based on the above, a specific embodiment of the rotating structure will be provided below to facilitate the understanding of the solution of the present invention.

[0046] In one embodiment, see Figure 3 and Figure 4 , the second end 122 and the fourth end 222 are hingedly connected by the rotating shaft member 3, the rotating shaft member 3, the second end 122 and the fourth end 222 are at least two, each rotating shaft member 3 is fixedly connected with a fourth end 222 respectively, in this embodiment, each rotating shaft member 3 is fixedly connected with a fourth end 222 respectively by rivet 4; and each rotating shaft member 3 is rotatably connected with a second end 122 respectively, in this embodiment, each second end 122 is wound around a rotating shaft member 3 respectively, so that the rotating shaft member 3 is rotatably connected with the second end 122. In this embodiment, there are two rotating shaft members 3, second ends 122 and fourth ends 222 respectively, wherein there are two first connecting members 12, and each first connecting member 12 includes a second end 122 respectively; there is one second connecting member 22, and the second connecting member 22 includes two fourth ends 222. In other embodiments, there may be one first connecting member 12, and the first connecting member 12 includes two second ends 122; there are two second connecting members 22, and each second connecting member 22 includes a fourth end 222, but the present invention is not limited thereto. Preferably, the axes of the at least two rotating shaft members 3 are colinear with each other and are arranged along the extension direction x of the axis of any rotating shaft member 3.

[0047] In another embodiment, see Figure 6, the second end 122 and the fourth end 222 are hingedly connected by the rotating shaft 3, the second end 122 is at least two, the fourth end 222 and the rotating shaft 3 are respectively one, and the rotating shaft 3 is a straight rotating shaft 3. The straight rotating shaft 3 is fixedly connected to the fourth end 222 (this part is omitted in the figure), and the at least two second ends 122 are rotatably connected to the straight rotating shaft 3. For example, the second end 122 is a sleeve 122, and the two sleeves 122 are respectively sleeved on the two opposite ends of the straight rotating shaft 3, so that the two sleeves 122 are rotatably connected to the straight rotating shaft 3. In other real examples, the at least two second ends 122 can also be respectively wound around the shaft wall of the straight rotating shaft 3 to be rotatably connected, and the present invention is not limited thereto.
