Description

Technical Field

[0001] This utility model relates to the field of desk lamp technology, and in particular to a desk lamp with built-in driver and multi-angle adjustment. Background Technology

[0002] A desk lamp is a lighting tool placed on a desk for users to use while working or studying. Existing desk lamps include a base, a connecting rod, a lampshade, and a light source. The light source is located on the lampshade, and the connecting rod is connected to both the base and the lampshade, allowing it to bend relative to the base and / or lampshade to adjust the light emission angle. Because the aforementioned desk lamps adjust the light emission angle by bending the connecting rod, the rod's support strength is insufficient, causing the lampshade to easily swing away from the preset position after adjustment, resulting in unsatisfactory adjustment. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-angle adjustable desk lamp with built-in drive, so as to solve the problem that the existing desk lamp adjusts the light output angle by bending the connecting rod. The supporting strength of the connecting rod is not good, which makes the lampshade easy to swing off the preset position after it is adjusted, resulting in poor adjustment effect.

[0004] This utility model is achieved through the following technical solution:

[0005] The built-in driver multi-angle adjustable desk lamp includes a lamp arm, a lampshade, and a light source. The lamp arm extends to the left and right, and a swing shaft connected to the lampshade is provided on the lamp arm. The swing shaft can rotate relative to the lamp arm, causing the lampshade to swing from below the lamp arm to one side of the lamp arm's axial direction. The light source is located inside the lampshade.

[0006] Furthermore, the lamp arm has a relief groove for receiving the swing shaft, and the swing shaft gradually receives itself in the relief groove or gradually moves out of the relief groove when it rotates relative to the lamp arm.

[0007] Furthermore, the swing shaft is connected to the side wall of the lampshade, and light is emitted from the bottom surface of the lampshade.

[0008] Furthermore, the outer wall of the lampshade is provided with a positioning hole for the insertion of the swing shaft.

[0009] Furthermore, the lamp arm has a drive cavity, and the drive cavity is provided with a driver that is electrically connected to the light source.

[0010] Furthermore, the lampshade has a light source cavity for accommodating the light source element, and the swing shaft has a wire channel connecting the light source cavity and the drive cavity.

[0011] Furthermore, the swing shaft is provided with a locking member to lock the lampshade on the swing shaft. The locking member has a communication channel connecting the wire channel and the light source cavity. One end of the locking member abuts against the lampshade, and the other end is embedded in the wire channel and threadedly connected to the swing shaft.

[0012] Furthermore, the lamp arm has an arm shell and an upper cover, the upper cover and the arm shell being detachably and fixedly connected to form the driving cavity; the lamp cover has a cover shell and a lower cover, the lower cover and the cover shell being detachably and fixedly connected to form the light source cavity, the lower cover being located on the lower side of the cover shell and being translucent.

[0013] Furthermore, it also includes a base and a pole, the pole extending vertically and connecting to the base and the lamp arm respectively.

[0014] The advantages of this technical solution are that by configuring a swing shaft connected to the lampshade on the lamp arm, the swing shaft can rotate relative to the lamp arm, causing the lampshade to swing from below the lamp arm to one side of the lamp arm axis to adjust the light emission angle. Since the adjustment of the light emission angle is completed by the rotation of the swing shaft, there is no deformation of the swing shaft and the lamp arm during the adjustment process. The swing shaft and the lamp arm have good structural strength, so the lampshade is not easy to shake and deviate from the target position after the light emission angle is adjusted to the right position, resulting in a good adjustment effect. Furthermore, since the lampshade swings from below the lamp arm to one side of the lamp arm axis when the swing shaft rotates relative to the lamp arm, the light emission angle adjustment range of the lampshade is wide.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-7 As shown, the built-in drive multi-angle adjustable desk lamp includes a lamp arm 1, a lampshade 2, and a light source 3. The lamp arm 1 extends left and right, and a swing shaft 4 connected to the lampshade 2 is provided on the lamp arm 1. The swing shaft 4 can rotate relative to the lamp arm 1, causing the lampshade 2 to swing from below the lamp arm 1 to one side of the lamp arm 1's axis. The light source 3 is located inside the lampshade 2. The swinging of the lampshade 2 from below the lamp arm 1 to one side of the lamp arm 1's axis means that the lampshade 2 can swing from below the lamp arm 1 to one side of the lamp arm 1's axis or from one side of the lamp arm 1's axis to below the lamp arm 1.

[0026] This embodiment provides a multi-angle adjustable desk lamp with a built-in driver to solve the problem of existing desk lamps adjusting the light output angle by bending a connecting rod. The connecting rod's support strength is insufficient, causing the lampshade to easily swing and deviate from the preset position after adjustment, resulting in poor adjustment effect. The solution mainly involves configuring a swing shaft 4 connected to the lampshade 2 on the lamp arm 1. The swing shaft 4 can rotate relative to the lamp arm 1, causing the lampshade 2 to swing from below the lamp arm 1 to one side of the lamp arm 1's axis to adjust the light output angle. Since the light output angle adjustment is completed through the rotation of the swing shaft 4, neither the swing shaft 4 nor the lamp arm 1 deforms during the adjustment process. The swing shaft 4 and the lamp arm 1 have good structural strength, thus preventing the lampshade 2 from easily shaking and deviating from the target position after the light output angle is adjusted, resulting in a good adjustment effect. Furthermore, because the swing shaft 4 causes the lampshade 2 to swing from below the lamp arm 1 to one side of the lamp arm 1's axis when rotating relative to the lamp arm 1, the light output angle adjustment range of the lampshade 2 is wide.

[0027] In this embodiment of the invention, the lamp arm 1 has a recess 101 for accommodating the swing shaft 4. As the swing shaft 4 rotates relative to the lamp arm 1, it gradually enters or exits the recess 101. This arrangement, by configuring the recess 101 on the lamp arm 1, allows the swing shaft 4 to gradually enter or exit the recess 101 as it rotates relative to the lamp arm 1, resulting in a compact and reasonable structure for the built-in drive multi-angle adjustable desk lamp.

[0028] In this embodiment of the invention, the swing shaft 4 is connected to the side wall of the lampshade 2, and the light source 3 emits light from the bottom surface of the lampshade 2. Specifically, when the lampshade 2 is swung to one side of the lamp arm 1 and abuts against the wall of the relief groove 101, the bottom surface of the lampshade 2 is parallel to the horizontal plane, and the lampshade 2 emits light vertically. When the lampshade 2 is swung below the lamp arm 1 and abuts against the wall of the relief groove 101, the bottom surface of the lampshade 2 is parallel to the vertical plane, and the lampshade 2 emits light horizontally. This configuration, by connecting the swing shaft 4 to the side wall of the lampshade 2 and emitting light from the bottom surface of the lampshade 2, allows for a wide range of adjustment of the light emission angle of the lampshade 2.

[0029] In this embodiment of the invention, the outer wall of the lampshade 2 is provided with a positioning hole 201 for the insertion of the swing shaft 4. The above arrangement, by providing a positioning hole 201 for the insertion of the swing shaft 4 on the outer wall of the lampshade 2, ensures stable assembly between the lampshade 2 and the swing shaft 4.

[0030] In this embodiment of the invention, the lamp arm 1 has a driving cavity 102, and a driver 5 electrically connected to the light source 3 is provided inside the driving cavity 102. This arrangement, by configuring the driving cavity 102 on the lamp arm 1 to house the driver 5, makes the structure of the built-in multi-angle adjustable table lamp compact and reasonable.

[0031] In this embodiment of the invention, the lampshade 2 has a light source cavity 202 for accommodating the light source element 3, and the swing shaft 4 has a wire channel 401 connecting the light source cavity 202 and the drive cavity 102. This arrangement, by configuring the wire channel 401 connecting the light source cavity 202 and the drive cavity 102 on the swing shaft 4, facilitates wiring between the light source element 3 and the driver 5.

[0032] In this embodiment of the invention, the swing shaft 4 is provided with a locking member 6 to lock the lampshade 2 onto the swing shaft 4. The locking member 6 has a connecting channel 601 that connects the wire channel 401 and the light source cavity 202. One end of the locking member 6 abuts against the lampshade 2, and the other end is embedded in the wire channel 401 and threadedly connected to the swing shaft 4. The above arrangement, by configuring the locking member 6 on the swing shaft 4 to detachably connect it to the lampshade 2, and configuring the connecting channel 601 on the locking member 6 to connect the wire channel 401 and the light source cavity 202, makes it convenient to assemble and disassemble the swing shaft 4 and the lampshade 2, while also facilitating the wiring of the light source 3 and the driver 5.

[0033] In this embodiment of the invention, the lamp arm 1 has an arm housing 103 and an upper cover 104, the upper cover 104 and the arm housing 103 being detachably and fixedly connected to form a drive cavity 102. The above arrangement, by configuring the lamp arm 1 to be detachably and fixedly connected to the arm housing 103 and the upper cover 104 forming the drive cavity 102, facilitates the installation and removal of the driver 5.

[0034] In this embodiment of the invention, the lampshade 2 has a housing 203 and a lower cover 204. The lower cover 204 is detachably and fixedly connected to the housing 203 to form a light source cavity 202. The lower cover 204 is located on the lower side of the housing 203 and is light-transmitting. This arrangement, by configuring the lampshade 2 as a detachable and fixedly connected housing 203 and lower cover 204 to form the light source cavity 202, facilitates the assembly and disassembly of the light source component 3.

[0035] In this embodiment of the utility model, a base 7 and a support rod 8 are also included. The support rod 8 extends vertically and is connected to the base 7 and the lamp arm 1 respectively. The support rod 8 is connected to the end of the lamp arm 1 away from the swing axis 4.
