Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a wall lamp that can be rotated and has a detachable package. Background Technology

[0002] Existing wall lamps generally employ a relatively complex connection structure to achieve electrical connection and fixation, while also being smaller in size for subsequent packaging and transportation.

[0003] However, existing desk lamps have relatively complex structures and limited functions.

[0004] For example, Chinese patent CN202322400110.4 uses the combination of a rotating part and a light-emitting body to achieve adjustment in the first and second directions. Consequently, it has more parts and higher production costs. At the same time, the structure of the rotating part is also more complex and more expensive.

[0005] Meanwhile, in order to achieve the linkage control of its multiple light-emitting bodies, its control principle is also quite complex. It mainly involves the rotating parts (which are quite complex in structure) which need to realize the combination of positive and negative poles and control circuits. In addition, in order to hide the circuits, a special wire-hiding cavity is also required, making the structure quite complex. Utility Model Content

[0006] The main purpose of this utility model is to propose a steerable and detachable wall lamp, which aims to improve the existing lamp structure, so that the reflector can be adjusted in all directions and the control circuit can be linked. At the same time, the electrical connection of the circuit is realized through quick connectors, eliminating the need for a hidden wire cavity. The structure is simple and the cost is low.

[0007] To achieve the above objectives, this utility model proposes a steerable and detachable wall lamp, comprising:

[0008] The base is a housing with an inner cavity. The housing is equipped with a transformer and a power supply device. The power supply device includes alternating current and a main battery connected to the alternating current.

[0009] The support column extends upward from the middle of the base, and two transverse columns extend towards each other from the top of the support column.

[0010] The universal joint has a hollow tube. One end of the universal joint is connected to a transverse column, and the other end has a circular first electrical connection part. The hollow tube is used for cables to pass through, and the two ends of the cables are respectively connected to the main battery and the first electrical connection part.

[0011] A light-emitting element is detachably mounted to the end of a universal joint. One end of the light-emitting element has a second electrical connection portion that mates with a first electrical connection portion. The light-emitting element includes a lamp housing and a lamp strip disposed within the lamp housing. One end of the lamp housing has a second electrical connection portion that connects to the first electrical connection portion.

[0012] The light-emitting element can rotate along the axial direction of the first electrical connection and the second electrical connection, and the universal joint can swing and be limited at multiple angles;

[0013] A control device, located in the main battery, is used to control the on and off of the light-emitting element.

[0014] In actual design, the universal joint allows the light-emitting body to swing at any angle. At the same time, by setting the universal joint to a hollow angle, the structure is simpler when the first electrical connection part is connected to the main battery (such as PCB board soldering).

[0015] At the same time, through the cooperation of the first electrical connection and the second electrical connection, the axis can be rotated, and the corresponding irradiation surface can be adjusted.

[0016] Compared to the comparison document, its structure is simpler, more stable, and has lower production costs. For example, the first and second electrical connection parts can be implemented using existing audio connector interfaces, and the switching between positive and negative terminals is possible.

[0017] Meanwhile, during transportation, the light-emitting element can be disassembled and packaged for transport, reducing the overall size of the structure, lowering transportation costs, and simplifying assembly.

[0018] Its design features include the use of standard connectors, such as audio connectors, to reduce production costs. At the same time, it allows for rotation and enables relatively stable current flow to achieve functions such as charging, conduction, and control. Attached Figure Description

[0037] like Figures 1 to 6 As shown, a steerable and removable wall lamp includes:

[0038] The base 1 is a shell with an inner cavity 11. The shell is equipped with a transformer and a power supply device. The power supply device includes AC power and a main battery 12 connected to the AC power.

[0039] Support column 2 extends upward from the middle of the base 1, and two transverse columns 21 extend towards each other from the top of the support column 2.

[0040] Universal joint 8, the universal joint 8 is provided with a hollow tube, one end of the universal joint 8 is connected to the transverse column 21, and the other end is provided with a circular first electrical connection part 41. The hollow tube is used for cables to pass through, and the two ends of the cables are respectively connected to the main battery 12 and the first electrical connection part 41.

[0041] The light-emitting element is detachably mounted to the end of the universal joint 8. One end of the light-emitting element is provided with a second electrical connection part 42 that cooperates with the first electrical connection part 41. The light-emitting element includes a lamp housing 30 and a lamp strip 3 disposed within the lamp housing 30. One end of the lamp housing 30 is provided with a second electrical connection part 42 that connects to the first electrical connection part 41.

[0042] The light-emitting element can rotate along the axial direction of the first electrical connection part 41 and the second electrical connection part 42, and the universal joint 8 can swing and be limited at multiple angles;

[0043] A control device is located in the main battery 12 and is used to control the opening and closing of the light-emitting element.

[0044] In the actual design, the universal joint 8 is set so that the light-emitting body can swing at any angle. At the same time, by setting the universal joint 8 to a hollow angle, the structure is simpler when the first electrical connection part 41 is connected to the main battery 12 (such as the PCB board 31 welding structure).

[0045] At the same time, through the cooperation of the first electrical connection part 41 and the second electrical connection, the axis can be rotated, and the corresponding irradiation surface can be adjusted.

[0046] Compared with the prior art, its structure is simpler, more stable, and has lower production costs. For example, the first electrical connection part 41 and the second electrical connection part 42 can be implemented using existing audio connector interfaces, and the switching between positive and negative terminals is possible.

[0047] Meanwhile, during transportation, the light-emitting element can be disassembled and packaged for transport, reducing the overall size of the structure, lowering transportation costs, and simplifying assembly.

[0048] Specifically, the universal joint 8 includes a base with a pivot cavity 81, a sphere 82 disposed in the pivot cavity 81, and a column 83 extending outward from the sphere 82. Both the sphere 82 and the column 83 are hollow structures.

[0049] The first electrical connection part 41 is disposed inside the main body.

[0050] The sphere 82 can swing circumferentially along the axis of the pivot cavity 81, thereby realizing the swing of the relative angle of the light-emitting body and thus adjusting its relative position.

[0051] In this embodiment of the utility model, the pivot cavity 81 is provided with an opening 81a, the opening 81a being larger than the maximum outer diameter of the column 83, and the maximum outer diameter of the sphere 82 being larger than the inner diameter of the opening 81a.

[0052] The outer wall of the sphere 82 is provided with an elastic ring 84, which enables the relative position of the universal joint 8 to be suspended and fixed. The structure is simple and stable, and the elastic ring 84 can apply a predetermined damping effect.

[0053] Specifically, the base is provided with an external thread 85 at the end away from the column 83, and the transverse column 21 is provided with an internal thread that mates with the external thread 85, which facilitates assembly. Of course, glue can also be used for bonding.

[0054] In this embodiment of the invention, the first electrical connection portion 41 is a plug-in portion 61, and the plug-in portion 61 is provided with a first conductive structure.

[0055] The second electrical connection part 42 is a plug groove 62 that mates with the plug part 61. The inner wall of the plug groove 62 is provided with a second conductive structure that mates with the first conductive structure.

[0056] Specifically, the first conductive structure is at least one conductive ring 51 disposed on the outer peripheral wall of the insertion part 61, the conductive ring 51 is a recessed structure, and the second conductive structure is a contact ring 52 that cooperates with the conductive ring 51.

[0057] When the insertion part 61 extends into the insertion slot 62, the conductive ring 51 and the contact ring 52 elastically abut or fit together. This achieves an electrical connection structure between the base 1 and the light-emitting body. At this time, the power supply of the base 1 can directly power the light-emitting body. The design can be customized according to the circuit requirements. For example, the control switch can be connected to the main switch of the base 1, or only a separate control switch can be provided.

[0058] In this embodiment of the utility model, when two conductive rings 51 are provided, each conductive ring 51 includes a positive terminal and a negative terminal. The positive terminal is connected to the control device, and its structure can be referenced to an audio cable. Because its power is low, a smaller current can be used to supply power.

[0059] Of course, the positions of the conductive ring and the contact ring can also be interchanged to achieve the purpose of conducting electricity.

[0060] When the conductive ring 51 is provided in three parts, namely the negative terminal, the positive terminal and the control terminal, its structure can be referenced to the audio cable. Because its power is low, a small current can be used to power it; for example, to control the brightness of the light-emitting element.

[0061] Specifically, the outer wall of the lamp housing 30 is provided with an elongated through hole, and a light guide plate 33 is provided in the through hole. The lamp strip 3 includes a PCB board 31 and LED beads 32 disposed on the PCB board 31.

[0062] The control device 35, lithium battery 34 and second electrical connection part 42 are all connected to PCB board 31. In actual production, PCB board 31 is used as a carrier, which facilitates assembly and control.

[0063] In this embodiment of the utility model, the outer peripheral wall of the plug-in part 61 is provided with a recessed slot 71, and the slot 71 is provided with a damping ring 72. When the plug-in part 61 extends into the plug-in slot 62, the damping ring abuts against the inner wall of the plug-in slot, thereby allowing the light from the light guide plate 33 to be irradiated at a predetermined angle, while simultaneously fixing the light source and the support column 2.

[0064] Specifically, the lower wall of the base 1 is provided with a hook hole, which is used to hook the base 1 to the wall.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
