Description

Technical Field

[0001] This utility model specifically relates to an LED office lamp. Background Technology

[0002] LED lighting fixtures are a general term for LED lamps, referring to devices that can transmit, distribute, and change the light distribution of LED light sources. This includes all components and parts required to fix and protect the LED light source, as well as the wiring accessories necessary for connecting to the power supply. In the 21st century, the design of residential lighting fixtures will be dominated by LED lighting fixtures, while fully reflecting the development trends of energy saving, health, artistry, and humanization, becoming the leader of residential lighting culture.

[0003] LED office lamps, also known as LED desk lamps, are energy-saving and do not harm eyesight. They are commonly used in offices and studies. To facilitate user operation, the lighting and fixing parts of the lamps are rotatably connected, allowing for easy adjustment of the lighting angle. However, the current rotatable connection between the lighting and fixing parts is not convenient for users to disassemble, preventing the lighting part from being removed for portable use. Consequently, the lamps are limited in function and can only be used as a whole.

[0004] Therefore, it is necessary to provide an LED office light structure to improve upon the problems mentioned above. Utility Model Content

[0005] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide an LED office lamp.

[0006] An LED office lamp includes a base and a support rod mounted on the base. The upper end of the support rod is provided with a lamp holder, and the lamp holder is provided with an LED lamp module. One end of the support rod has a circular protrusion, and one end of the lamp holder has a circular cavity that can rotate with the circular protrusion. The side wall of the circular protrusion has a limiting groove recessed along its circumference. A cover plate is detachably connected to one side of the lamp holder, and a limiting flange protrudes outward from one side of the cover plate. The limiting flange is movably disposed in the limiting groove and can rotate circumferentially with the lamp holder around the circular protrusion.

[0007] In one embodiment, the lamp holder has a battery cavity with an opening on one side, and the battery cavity is connected to the circular recess by an opening. The cover plate is detachably placed over the opening of the battery cavity, and the limiting flange is movably accommodated in the limiting groove through the opening.

[0008] In one embodiment, one end of the cover plate is rotatably connected to the lamp holder, and the other end of the cover plate is provided with a snap-fit ​​strip that can be elastically deformed. One side of the lamp holder is provided with a slot that can engage with the snap-fit ​​strip. When the snap-fit ​​strip is engaged in the slot, the cover plate remains in a connected state with the battery cavity opening.

[0009] In one embodiment, the inner wall of the circular cavity is provided with a rubber friction pad that can abut against the circular protrusion.

[0010] In one embodiment, the lamp holder further has a lamp cavity with an opening on one side, and the LED lamp module is disposed inside the lamp cavity.

[0011] In one embodiment, the LED light module includes an LED light panel and a light-transmitting cover.

[0012] In one embodiment, the support rod includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably mounted on a fixed base via a damping structure, and the other end of the first connecting rod is rotatably connected to the second connecting rod via a damping structure. The circular protrusion is formed at one end of the second connecting rod.

[0013] In one embodiment, an anti-slip pad is provided on the underside of the mounting base.

[0014] In summary, the advantages of this utility model over the prior art are:

[0015] This invention utilizes the interlocking of a circular cavity in the lamp holder with a circular protrusion on the support rod to allow the lamp holder to rotate circumferentially around the protrusion. This allows the user to rotate the lamp holder to change the lighting direction of the LED module on it, thus meeting the user's needs. Furthermore, when the cover plate is fixed to the lamp holder, the limiting flange on the cover plate is located within the limiting groove of the circular protrusion. This ensures that the circular protrusion and the circular cavity maintain a fitted fit while also allowing the lamp holder to rotate relative to the circular protrusion. When the lamp holder needs to be separated, only the cover plate needs to be removed so that the limiting flange on the cover plate disengages from the limiting groove. This satisfies the user's need to disassemble and carry the lamp holder separately, making assembly and disassembly simple. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 4 The present invention preferably provides an LED office lamp, including a fixed base 1 and a support rod 2 disposed on the fixed base 1. The upper end of the support rod 2 is provided with a lamp holder 3, and the lamp holder 3 is provided with an LED lamp module 4. One end of the support rod 2 has a circular protrusion 5. One end of the lamp holder 3 has a circular cavity 6 that can rotate with the circular protrusion 5. The side wall of the circular protrusion 5 has a limiting groove 7 recessed along the circumference. A cover plate 8 is detachably connected to one side of the lamp holder 3. One side of the cover plate 8 has a limiting flange 9 protruding outward. The limiting flange 9 is movably disposed in the limiting groove 7 and can rotate circumferentially with the lamp holder 3 around the circular protrusion 5.

[0022] Specifically, the circular cavity of the lamp holder engages with the circular protrusion of the support rod, allowing the lamp holder to rotate circumferentially around the protrusion. This enables the user to rotate the lamp holder to change the lighting direction of the LED module on it, meeting the user's needs. When the cover plate is fixed to the lamp holder, the limiting flange on the cover plate is located within the limiting groove of the circular protrusion. This ensures that the circular protrusion and the circular cavity maintain a fitted engagement while also allowing the lamp holder to rotate relative to the circular protrusion. When the lamp holder needs to be separated, simply remove the cover plate to disengage the limiting flange from the limiting groove. This allows users to easily disassemble and carry the lamp holder, making assembly and disassembly simple.

[0023] Furthermore, the lamp holder 3 has a battery cavity 10 with an opening on one side. An opening 11 connects the battery cavity 10 to the circular recess 6. The cover plate 8 is detachably placed over the opening of the battery cavity 10, and the limiting flange 9 is movably accommodated within the limiting groove 7 through the opening 11. Moreover, when the cover plate is installed and fixed on the lamp holder, it can also serve as a cover for the battery cavity, reducing component costs. Furthermore, when the battery inside the battery cavity needs to be replaced, the user can remove the cover plate, allowing the lamp holder to separate and the battery to be directly replaced, avoiding the drawback of having to remove the battery cover after separating the lamp holder to replace the battery.

[0024] Furthermore, one end of the cover plate 8 is rotatably connected to the lamp holder 3, and the other end of the cover plate 8 is provided with a snap-fit ​​strip 12 that can elastically deform. One side of the lamp holder 3 is provided with a slot 13 that can engage with the snap-fit ​​strip 12. When the snap-fit ​​strip 12 is engaged in the slot 13, the cover plate 8 remains in a connected state where it is placed over the opening of the battery cavity 10. Thus, the snap-fit ​​connection between the cover plate and the lamp holder is achieved through the snap-fit ​​strip engaging with the slot.

[0025] Furthermore, the inner wall of the circular cavity 6 is provided with a rubber friction pad that can abut against the circular protrusion 5. This rubber friction pad effectively increases the friction between the circular cavity and the circular protrusion, thereby increasing the damping between them and facilitating adjustment of the lamp holder after rotation relative to the circular protrusion.

[0026] Furthermore, the lamp holder 3 also has a lamp cavity 14 with an opening on one side, and the LED lamp module 4 is disposed in the lamp cavity 14.

[0027] Furthermore, the LED lamp module 4 includes an LED lamp board and a light-transmitting cover.

[0028] Furthermore, the support rod 2 includes a first connecting rod 21 and a second connecting rod 22. One end of the first connecting rod 21 is rotatably mounted on the fixed base 1 via a damping structure, and the other end of the first connecting rod 21 is rotatably connected to the second connecting rod 22 via the damping structure. The circular protrusion 5 is formed at one end of the second connecting rod 22. Specifically, the damping structure is a relatively mature existing technology, and its structural principle will not be described in detail here. The first and second connecting rods work together to facilitate multi-directional adjustable illumination of the LED lamp module on the lamp holder.

[0029] Furthermore, an anti-slip pad 23 is provided on the lower side of the fixing base 1, thereby effectively increasing the friction when the fixing base is placed.
