When the learning and working area is relatively concentrated, the light needs to be concentrated in the working area. However, the lighting area of the existing desk lamp is usually fixed, and when a long lighting area is needed, the entire desk lamp sometimes needs to be moved to illuminate the target area, which is inconvenient to use. INVENTION CONTENTS

[0005] The utility model aims at overcoming at least one defect (deficiency) of the above prior art, providing a foldable lampshade of lamp and lamp, which is convenient to adjust the lighting area of the lamp.

[0006] One object of the utility model is to provide a foldable lampshade of lamp, which comprises a support rod, the foldable lampshade comprises a fixed lamp arm, a first folding arm and a second folding arm, the fixed lamp arm, the first folding arm and the second folding arm are all provided with light emitting devices,

[0007] The fixed lamp arm is connected to the top end of the lamp rod, the first folding arm is rotatably connected to one end of the fixed lamp arm, and the second folding arm is rotatably connected to the other end of the fixed lamp arm.

[0008] The first folding arm and the second folding arm can be folded back by rotating, when the first folding arm and the second folding arm are rotated forward to fully unfold, the first folding arm and the second folding arm form an obtuse angle with the fixed lamp arm respectively.

[0009] In the technical solution, the fixed lamp arm, the first folding arm and the second folding arm are all components for fixing light emitting devices, the light emitting devices on different arms can be the same or different, for example, different color light emitting devices are installed on different arms according to requirements, so as to meet more use requirements.

[0010] The forward rotation is rotation towards the use side, and the backward rotation is rotation towards the side away from the use side.

[0011] When the two folding arms rotate forward, the lampshade is in an unfolded state, the length of the lampshade is elongated as a whole, and the sides of the fixed lamp arm are also lighting areas, meeting the use requirement of a longer lighting area, for example, when a user uses a computer with double displays, the user can make the area of the two displays have sufficient lighting. When the lampshade is completely unfolded, the first folding arm and the second folding arm form an obtuse angle with the fixed lamp arm respectively, so that the first folding arm, the fixed lamp arm and the second folding arm form an elongated and bent lampshade, which can adapt to the curvature of the fish screen when the user uses a curved fish screen, and ensure the lighting effect of each area of the screen. In addition, the light emitting devices of the folding arms form light sources on the left and right sides of the fixed lamp arm, which can reduce the shadow of objects on the desktop to a certain extent and optimize the user experience.

[0012] When the two folding arms are rotated backward to be retracted, the lampshade is in a folded state, at this time, the lighting area in the middle of the lampshade has light from the fixed lamp arm and light from the two folding arms, which enhances the brightness of the lighting area in the middle of the lampshade.

[0013] Further, the light emitting device has a light emitting surface, when the first folding arm and the second folding arm are completely unfolded, the light emitting surface is inclined to the height direction of the foldable lampshade and faces the front side.

[0014] In the technical solution, the front side refers to the use side, and the inclination refers to that the light emitting surface is neither parallel to the height of the lampshade nor perpendicular to the height of the lampshade. Compared with the perpendicular downward arrangement, the inclined arrangement of the light emitting surface can increase the area of the lighting area and improve the utilization rate of light. The light emitting surface facing the front side can move the lighting area forward and close to the user, so that the user can touch the lighting area without moving the lamp forward, which is convenient for the user to use, and the lamp does not need to be moved forward, so that the user can have a larger learning and working area.

[0015] Further, when the folding arms are retracted, the light emitting surface on the folding arm and the light emitting surface on the fixed lamp arm are opposite, that is, the light emitting surface on the folding arm faces the rear side, and the light emitting surface on the fixed lamp arm faces the front side, which greatly expands the lighting area and improves the lighting brightness of the middle area.

[0018] Further, the rear side sheet is provided with an extension portion downward, and the extension portion, the first inclined sheet and the second inclined sheet openly enclose a light emitting device accommodating space.

[0019] Further, the included angle between the first inclined sheet and the height direction of the foldable lampshade is 40°-70°.

[0020] Further, when the first folding arm and the second folding arm are folded and stored by rotating backward, the first folding arm and the second folding arm are both parallel to the fixed lamp arm.

[0021] Further, the fixed lamp arm is provided with a control panel electrically connected with the light emitting device.

DETAILED DESCRIPTION

[0039] The drawings of the utility model are only used for exemplary illustration and cannot be understood as a limitation of the utility model. In order to better illustrate the following embodiments, some components of the drawings can be omitted, enlarged or reduced, and the size of the actual product is not represented; for those skilled in the art, it can be understood that some well-known structures and their descriptions in the drawings can be omitted.

[0040] Example 1

[0041] Reference Figures 1 to 3 ​​This embodiment provides a foldable lampshade for a lamp fixture. The lamp fixture includes a support rod 500. The foldable lampshade includes a lamp arm assembly, a fixed lamp arm 100, a first folding arm 110, and a second folding arm 120. The fixed lamp arm 100, the first folding arm 110, and the second folding arm 120 are all equipped with light-emitting devices. The fixed lamp arm 100 is connected to the top end of the lamp rod. The first folding arm 110 is rotatably connected to one end of the fixed lamp arm 100, and the second folding arm 120 is rotatably connected to the other end of the fixed lamp arm 100. The first folding arm 110 and the second folding arm 120 can be rotated backward and folded up. When the first folding arm 110 and the second folding arm 120 are rotated forward to be fully unfolded, the first folding arm 110 and the second folding arm 120 respectively form obtuse angles with the fixed lamp arm 100.

[0042] The fixed lamp arm 100, the first folding arm 110, and the second folding arm 120 are all components used to fix the light-emitting devices. The light-emitting devices on different arms can be the same or different. For example, light-emitting devices of different colors can be installed on different arms according to requirements, thereby meeting more usage requirements.

[0043] The forward rotation refers to rotation toward the side of use, while the backward rotation refers to rotation toward the side away from the side of use.

[0044] When the two folding arms rotate forward, the lampshade is in the unfolded state, and its overall length is extended. The sides of the fixed lamp arm 100 also become illuminated areas, meeting the needs of users requiring a longer illumination area. For example, if the user is using a dual-monitor computer, both monitor areas can be adequately illuminated. When the lampshade is fully unfolded, the first folding arm 110 and the second folding arm 120 form an angle α with the fixed lamp arm 100. An angle α is obtuse, causing the first folding arm 110, the fixed lamp arm 100, and the second folding arm 120 to form an extended and bent lampshade. When the user is using a curved ultrawide monitor, the shape of this lampshade can adapt to the curvature of the ultrawide screen, ensuring effective illumination in all areas of the screen. Furthermore, the light-emitting devices of the folding arms form light sources on the left and right sides of the fixed lamp arm 100, which can reduce shadows on objects on the desktop to some extent, optimizing the user experience.

[0045] Combination Figure 7 When the two folding arms rotate backward and retract, the lampshade is in a folded state. At this time, the lighting area in the center of the lampshade receives light from both the fixed lamp arm 100 and the two folding arms, enhancing the brightness of the lighting area in the center of the lampshade. Furthermore, when the first folding arm 110 and the second folding arm 120 rotate backward and retract, both the first folding arm 110 and the second folding arm 120 are parallel to the fixed lamp arm 100. This makes the folded state more aesthetically pleasing.

[0046] refer to Figure 8 andFigure 9 The rotating connection between the first folding arm 110 and the second folding arm 120 and the fixed arm can be hinged or connected through a rotating shaft, etc. The following is an exemplary reference of the rotating connection. The folding arm described below can be the first folding arm 110 or the second folding arm 120. In the present exemplary scheme, the folding arm is connected with the fixed lamp arm 100 through a connecting assembly. The connecting assembly comprises a first rotating block 410 and a second rotating block 420 arranged below the first rotating block 410. The first rotating block 410 is connected with the fixed lamp arm 100, and a rotating column 411 is arranged on the first rotating block 410. The second rotating block 420 is connected with the folding arm, and a fixing piece 421 is arranged in the second rotating block 420. The fixing piece 421 is provided with a limiting protrusion 4211 matched with the rotating column 411. The rotating column 411 is inserted into the limiting protrusion 4211, and the two can rotate relative to each other. When the user bends the folding arm, the folding arm drives the second rotating block 420 to rotate, and the limiting protrusion 4211 rotates relative to the rotating column 411, so as to realize the rotation of the folding arm relative to the fixed lamp arm 100. When the folding arm is fully unfolded, the edge of the folding arm and the fixed lamp arm 100 abut, limiting the folding arm from continuing to rotate forward.

[0047] Reference Figure 5 And Figure 6 The light emitting device has a light emitting surface 210. When the first folding arm 110 and the second folding arm 120 are fully unfolded, the light emitting surface 210 is inclined to the height direction of the foldable lampshade and faces the front side.

[0048] Here, the front side refers to the use side. The inclination refers to that the light emitting surface 210 is not parallel to the height of the lampshade, nor perpendicular to the height of the lampshade. Compared with the perpendicular downward arrangement, the inclined arrangement of the light emitting surface 210 can increase the area of the illumination area and improve the utilization rate of light. The light emitting surface 210 facing the front side can move the illumination area forward and close to the user, so that the user can touch the illumination area without moving the lamp forward, which is convenient for the user to use. Moreover, the lamp does not need to be moved forward, so that the user can have a larger learning and working area.

[0049] Further, when the folding arm is folded, the light emitting surface 210 on the folding arm and the light emitting surface 210 on the fixed lamp arm are opposite, i.e. the light emitting surface 210 on the folding arm faces the rear side, and the light emitting surface 210 on the fixed lamp arm 100 faces the front side, which greatly expands the illumination area and improves the illumination brightness of the middle area.

[0050] Exemplarily, the fixed lamp arm 100, the first folding arm 110 and the second folding arm 120 each comprise a lamp arm body, the lamp arm body comprises a first inclined sheet 350, the first inclined sheet 350 gradually inclines downward from front to back, the light emitting device is installed on the first inclined sheet 350, and the inclination of the light emitting surface 210 is the same as the inclination of the first inclined sheet 350. Further, the included angle between the first inclined sheet 350 and the height direction of the foldable lampshade is 40°-70°.

[0051] In order to make the light emitting surface 210 in an inclined state, if the inclined installation of the light emitting device is difficult and the operation is troublesome, the first inclined sheet 350 is arranged in the scheme, and the inclined installation of the light emitting surface 210 can be realized by directly installing the light emitting device thereon, which is convenient to operate and can be suitable for different types of light emitting devices. In addition, the inclination of the light emitting surface 210 of the light emitting device is the same as the inclination of the first inclined sheet 350, which can be understood as that the light emitting surface 210 is parallel to the first inclined sheet 350, if the light emitting surface 210 is a curved surface, the connecting line of the two end points of the cross section is parallel to the first inclined sheet 350, the first inclined sheet 350 and the lampshade height direction form an included angle β, the included angle β is 40°-70°, for example, 45°, 50°, 60°, etc. The appropriate inclination angle of the first inclined sheet 350 can avoid the illumination area from moving forwardly insufficiently, and also avoid the illumination area from moving forwardly excessively to irradiate the user's eyes.

[0052] Exemplarily, the lamp arm body is formed by sequentially connecting the rear side sheet 310, the top sheet 320, the front side sheet 330, the second inclined sheet 340 and the first inclined sheet 350, the first inclined sheet 350 and the second inclined sheet 340 are integrally connected, the end of the first inclined sheet 350 away from the second inclined sheet 340 gradually inclines downward from front to back to connect the rear side sheet, and the end of the second inclined sheet 340 away from the first inclined sheet 350 gradually inclines downward from back to front to connect the front side sheet 330.

[0053] The first inclined sheet 350 and the second inclined sheet 340 form a similar inverted V-shaped angle, the length of the front side sheet 330 is preferably greater than that of the rear side sheet 310, and the front side sheet 330 and the second inclined sheet 340 form a light blocking part to prevent the light emitting surface 210 from being set too far forwardly to irradiate the user's eyes and avoid causing discomfort to the user.

[0054] Further, the rear side sheet 310 is provided with an extension 311 downwardly, and the extension 311, the first inclined sheet 350 and the second inclined sheet 340 openly enclose a light emitting device containing space.

[0055] The light emitting device is connected to the first inclined plate 350 and placed in the accommodating space, and the extension 311 and the second inclined plate 340 can provide more mounting sites for the light emitting device and improve the connection firmness. Specifically, the extension 311 is arranged in a curved manner, and the curved direction is towards the inside of the accommodating space. The light emitting device can be a lamp strip, and the lamp strip comprises a cover 230 and a base 220 with LED lamps. The cover 230 is a light emitting surface 210. The extension 311 is provided with a first protruding strip 3111, and the second inclined plate 340 is provided with a second protruding strip 341. The first protruding strip 3111 and the second protruding strip 341 form a base clamping groove 351 with the first inclined plate 350 respectively. The first protruding strip 3111 forms a cover clamping groove 3112 with the edge of the extension 311. The second protruding strip 341 is provided with another cover clamping groove 3112 on the second inclined plate 340, away from the side of the base clamping groove. The base 220 of the lamp strip is clamped in the base clamping groove, and the cover 230 of the lamp strip is clamped in the cover clamping groove 3112. The LED lamps on the base 220 emit light through the cover 230.

[0056] Reference Figure 4 For example, the fixed lamp arm 100 is provided with a control panel 131 electrically connected to the light emitting device. Specifically, the fixed lamp arm 100 is connected to the support rod 500 through the connecting mechanism 130, and the control panel 131 is arranged on the connecting mechanism 130. The user can control the switch, brightness and the like of each light emitting device through the keys on the control panel 131.

The top end of the support rod 500 is connected to the foldable lampshade, and the bottom end of the support rod 500 is connected to the lamp holder 600. The bottom end of the support rod 500 is detachably connected to the lamp holder 600. The lamp holder 600 is a clamp or a pedestal. The use of the clamp can greatly reduce the occupied space of the lamp on the desktop. The use of the pedestal can facilitate the user to move and adjust the position of the lamp.
