[0001] The present application belongs to the technical field of lamps and lanterns, and specifically provides a desk lamp. BACKGROUND

[0002] A desk lamp is a lamp used to provide local lighting, which is usually placed on a flat surface such as a desktop, a bookshelf, or a bedside table, to meet the light requirements of various close-range work or activities such as reading, writing, handicraft making, computer operation, and leisure reading.

[0003] The existing desk lamp generally includes a lamp head for lighting and a lamp base for supporting the lamp head. In use, the lamp base needs to be placed flat on the aforementioned flat surface, and cannot be placed on a vertical or inclined flat surface, resulting in limited use scenarios of the desk lamp and difficulty in meeting the increasing personalized needs of users. Especially for special scenarios such as student dormitories, workshops, and warehouses, users often need to fix the desk lamp to a vertical flat surface. SUMMARY

[0004] One object of the present application is to solve the problem that the existing desk lamp cannot be placed on a vertical flat surface.

[0005] To achieve the above object, the present application provides a desk lamp, comprising:

[0006] a lamp head comprising a light-emitting module;

[0007] a lamp base comprising a seat body and a magnet installed on the seat body, the seat body being provided with an avoidance hole with an opening facing downward, the magnet being arranged in the avoidance hole, and the magnet being exposed by the avoidance hole; in the up-down direction of the desk lamp, the bottom surface of the magnet is located inside the avoidance hole, and the spacing between the bottom surface of the magnet and the bottom surface of the lamp base is selected from any value in the range of 0.05mm to 3mm.

[0008] Optionally, the spacing between the bottom surface of the magnet and the bottom surface of the lamp base is selected from any value in the range of 0.05mm to 1mm.

[0009] Optionally, the spacing between the bottom surface of the magnet and the bottom surface of the lamp base is 0.1mm.

[0010] Optionally, the ratio of the diameter of the avoidance hole to the diameter of the bottom surface of the lamp base is selected from any value in the range of 2 / 5 to 7 / 9.

[0011] Optionally, the ratio of the diameter of the avoidance hole to the diameter of the bottom surface of the lamp base is 2 / 3 or 3 / 5 or 4 / 7; and / or the avoidance hole is formed at the center of the lamp base in the lateral direction of the desk lamp.

[0012] Optionally, the base body comprises a bottom shell connected with the lamp head and opening downward, a bottom plate for shielding the bottom shell, and a base plate arranged between the bottom shell and the bottom plate, the base plate being provided with a charging connector; the avoiding hole is formed on the bottom plate; the magnet is fixedly connected with the base plate.

[0013] Optionally, the base plate is provided with a U-shaped hole penetrating the base plate in the up-down direction of the desk lamp, the base plate is provided with a base plate threaded hole on each of opposite sides of the U-shaped hole; the magnet is provided with a magnet through hole corresponding to the base plate threaded hole; the lamp holder further comprises a magnet fixing screw, the magnet fixing screw penetrates the magnet through hole and is screwed into the base plate threaded hole.

[0014] Optionally, the base plate is further provided with a base plate mounting hole on the outer side of the base plate threaded hole away from the U-shaped hole; the base plate is fixed to the bottom shell through the base plate mounting hole.

[0015] Optionally, the lamp holder further comprises an annular fixing plate arranged between the base plate and the bottom plate, the fixing plate being provided with a fixing plate through hole; the bottom shell is provided with a bottom shell threaded hole corresponding to the base plate mounting hole; the lamp holder further comprises a base plate fixing screw, the base plate fixing screw penetrates the fixing plate through hole and the base plate mounting hole and is screwed into the bottom shell threaded hole; the magnet is gap-fitted with the bottom plate and the fixing plate respectively.

[0016] Optionally, the desk lamp further comprises a lamp rod arranged between the lamp head and the lamp holder; and / or the magnet is a circular sheet structure.

[0017] Based on the foregoing description, those skilled in the art can understand that, in the foregoing technical solutions of the present application, by arranging an opening downward avoiding hole on the base body, arranging a magnet in the avoiding hole, and exposing the magnet by the avoiding hole, the lamp holder of the desk lamp can be adsorbed on a metal surface by the magnet, so that the desk lamp of the present application can be adsorbed on a vertical or inclined metal plane. For example, the desk lamp of the present application can be adsorbed on the side wall of a bed frame in a student dormitory, adsorbed on the side of a metal cabinet in a warehouse, adsorbed on a machine in a workshop, etc. By arranging a gap between the bottom surface of the magnet and the bottom surface of the lamp holder, and selecting the gap from any value in the range of 0.05mm to 3mm, the magnet can be adsorbed on the metal surface while ensuring that the bottom surface of the base can be attached to the metal surface. When the magnet protrudes from the bottom surface of the base body, the base can be prevented from being warped or having a raised edge when the magnet is adsorbed on the metal surface.

[0018] Further, by selecting the ratio of the diameter of the avoiding hole to the diameter of the bottom surface of the lamp holder from any value in the range of 2 / 5 to 7 / 9, the magnet is ensured to be fixed to the seat body while having sufficient area to adsorb the metal surface, thereby ensuring the stability of the lamp holder when adsorbed to the metal surface.

[0019] Further, by providing a U-shaped hole penetrating the base plate in the upward and downward direction of the desk lamp, the base plate is fixedly connected with the magnet through the magnet fixing screw, fixedly connected with the bottom shell through the base plate fixing screw, and the base plate fixing screw is located outside the magnet fixing screw, so that the base plate can be slightly deformed when the magnet is adsorbed to the metal surface, making the magnet closer to the metal surface, the adsorption force is greater, and the fixation is more secure.

[0020] Further, by setting the magnet as a circular sheet structure, the material cost is reduced while ensuring that it can provide sufficient magnetic force to the desk lamp.

[0021] Other beneficial effects of the present application will be described in detail in the following with reference to the accompanying drawings, so that those skilled in the art can more clearly understand the improvement purposes, features and advantages of the present application.

[0065] As shown in FIGS. 3-5, in some embodiments of the present application, the plug-in part 110 is further provided with an upper connecting hole 1103, so that the plug-in part 110 is plugged together with the lamp rod 300 through the upper connecting hole 1103.

[0066] Similarly, the plug-in hole 1026 and the lamp rod 300 can be fixed together in an interference fit manner, so as to ensure the connection strength therebetween. Alternatively, the skilled in the art can also bond the two together by using adhesive or other adhesive substances according to the needs.

[0067] As shown in FIG. 6, in some embodiments of the present application, the lamp rod 300 is provided with a plug-in head 310 at each end, so that the lamp rod 300 is plugged together with the connecting hole on the plug-in part 110 through the plug-in head 310 at one end, thereby realizing the connection between the lamp rod 300 and the lamp holder 100; and the lamp rod 300 is plugged together with the lamp base 200 through the plug-in head 310 at the other end.

[0068] The lamp base 200 in some embodiments of the present application will be described in detail below with reference to FIGS. 7-10.

[0069] As shown in FIGS. 7-10, in some embodiments of the present application, the lamp base 200 comprises a base body 210 and a magnet 220 mounted on the base body 210.

[0070] The base body 210 is provided with an escape hole 2101 with an opening downward.

[0071] The magnet 220 is arranged in the escape hole 2101, and the magnet 220 is exposed by the escape hole 2101.

[0072] Further, the magnet 220 can be any feasible magnet, such as an aluminum-nickel-cobalt (AlNiCo) alloy magnet, a ferrite magnet, a iron-chromium-cobalt (FeCrCo) alloy magnet, etc.

[0073] Still further, the surface of the magnet 220 can be coated with a protective layer, such as a plastic protective layer, a rubber protective layer, a silica gel protective layer, etc.

[0074] In the up-down direction of the desk lamp 001, the bottom surface of the magnet 220 is located in the avoiding hole 2101, and the spacing L between the bottom surface of the magnet 220 and the bottom surface of the lamp holder 200 is selected from any value in the range of 0.05mm to 3mm.

[0075] As can be understood by those skilled in the art, by providing the avoiding hole 2101 with the opening facing downward on the seat body 210, and by setting the magnet 220 in the avoiding hole 2101 and allowing the magnet 220 to be exposed by the avoiding hole 2101, the lamp holder 200 of the desk lamp 001 can be adsorbed on a metal surface by the magnet 220, and thus the desk lamp 001 of the present application can be adsorbed on a vertical or inclined metal plane. For example, the desk lamp 001 of the present application can be adsorbed on the side wall of a bed frame in a student dormitory, on the side of a metal cabinet in a warehouse, on a machine in a workshop, etc.

[0076] Further, by allowing the spacing between the bottom surface of the magnet 220 and the bottom surface of the lamp holder 200, and by selecting the spacing L from any value in the range of 0.05mm to 3mm, the magnet 220 can be adsorbed on a metal surface while ensuring that the bottom surface of the base can be in close contact with the metal surface. This avoids the situation where the base is warped or has a raised edge when the magnet 220 is adsorbed on the metal surface.

[0077] Further, the spacing L between the bottom surface of the magnet 220 and the bottom surface of the lamp holder 200 is selected from any value in the range of 0.05mm to 1mm. For example, 0.05mm, 0.08mm, 0.09mm, 1mm, etc.

[0078] Preferably, the spacing L between the bottom surface of the magnet 220 and the bottom surface of the lamp holder 200 is 0.1mm.

[0079] As shown in FIG. 9, in some embodiments of the present application, the ratio of the diameter d of the avoiding hole 2101 to the diameter D of the bottom surface of the lamp holder 200 is selected from any value in the range of 2 / 5 to 7 / 9. For example, the ratio of the diameter d of the avoiding hole 2101 to the diameter D of the bottom surface of the lamp holder 200 is 2 / 3 or 3 / 5 or 4 / 7.

[0080] The skilled in the art can understand that by selecting the ratio of the diameter d of the avoiding hole 2101 to the diameter D of the bottom surface of the lamp holder 200 from any value in 2 / 5 to 7 / 9, the magnet 220 has sufficient area to adsorb the metal surface while ensuring that the magnet 220 is fixed to the seat body 210, thereby ensuring the stability of the lamp holder 200 when adsorbed to the metal surface.

[0081] As shown in FIGS. 7-9, in some embodiments of the present application, the avoiding hole 2101 is formed in the center of the lamp holder 200 in the lateral direction X of the desk lamp 001, so that the magnet 220 is located in the center of the lamp holder 200.

[0082] The skilled in the art can understand that by arranging the magnet 220 in the center of the lamp holder 200, the bottom surface of the seat body 210 is more stable when the magnet 220 is adsorbed to the metal surface.

[0083] As shown in FIGS. 7-9, the seat body 210 includes a bottom shell 211 connected to the lamp head 100 and opening downward, a bottom plate 212 for shielding the bottom shell 211, and a base plate 213 arranged between the bottom shell 211 and the bottom plate 212.

[0084] The bottom shell 211 is provided with a lower connecting hole 2111, so that the bottom shell 211 is inserted together with the plug 310 of the lamp stem 300 through the lower connecting hole 2111.

[0085] The base plate 213 is provided with a charging connector 214, which is electrically connected to the battery module 107 through an electric wire, so as to charge the battery module 107 when the charging connector 214 is connected to an external power source.

[0086] As shown in FIGS. 7 and 8, the base plate 213 is provided with a U-shaped hole 2131 extending therethrough in the up-down direction of the desk lamp 001, and a part of the charging connector 214 is located in the U-shaped hole 2131, so as to arrange a part of the electric wire electrically connected to the charging connector 214 in the U-shaped hole 2131.

[0087] Referring back to FIG. 6, the lamp stem 300 is a hollow structure, so that the electric wire connected to the charging connector 214 extends from the lamp stem 300 into the lamp head 100.

[0088] Further, as shown in FIGS. 7-9, the avoiding hole 2101 is formed in the bottom plate 212, and the magnet 220 is fixedly connected to the base plate 213.

[0089] As shown in FIGS. 7-9, the substrate 213 is provided with substrate threaded holes 2132 on opposite sides of the U-shaped hole 2131, and the magnet 220 is provided with magnet through holes 221 corresponding to the substrate threaded holes 2132. The lamp holder 200 further comprises magnet fixing screws 230, which pass through the magnet through holes 221 and are screwed into the substrate threaded holes 2132, thereby fixing the magnet 220 to the substrate 213.

[0090] Continuing to refer to FIGS. 7-9, the substrate 213 is further provided with substrate mounting holes 2133 on the outer side of the substrate threaded holes 2132 away from the U-shaped hole 2131, and the substrate 213 is fixed to the bottom shell 211 through the substrate mounting holes 2133. That is, in the radial direction of the substrate 213, the two substrate threaded holes 2132 are located on the inner side of the two substrate mounting holes 2133.

[0091] Further, the lamp holder 200 can further comprise an annular fixing plate 215 arranged between the substrate 213 and the bottom plate 212, and the fixing plate 215 is provided with a fixing plate through hole 2151. The bottom shell 211 is provided with bottom shell threaded holes 2112 corresponding to the substrate mounting holes 2133.

[0092] Further, the lamp holder 200 can further comprise substrate fixing screws 240, which pass through the fixing plate through hole 2151 and the substrate mounting hole 2133 and are screwed into the bottom shell threaded hole 2112 to achieve the fixation of the substrate 213.

[0093] As can be seen from FIGS. 9 and 10, in some embodiments of the present application, the magnet 220 is gap-fitted with the bottom plate 212 and the fixing plate 215, respectively.

[0094] As can be understood by those skilled in the art, by providing the U-shaped hole 2131 on the substrate 213 in the base that passes through the substrate 213 in the up-down direction of the desk lamp 001, fixing the substrate 213 to the magnet 220 through the magnet fixing screws 230, fixing the substrate 213 to the bottom shell 211 through the substrate fixing screws 240, and locating the substrate fixing screws 240 on the outer side of the magnet fixing screws 230, when the magnet 220 is adsorbed to the metal surface, the substrate 213 can be slightly deformed, so that the magnet 220 is closer to the metal surface, the suction force is greater, and the fixation is more secure.

[0095] Further, as can be seen from FIGS. 7-9, the magnet 220 is a circular sheet structure, which reduces the material cost while ensuring that it can provide sufficient magnetic force to the desk lamp 001.
