Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and more particularly to a lighting device having a flashlight mode and a table lamp mode. Background Technology

[0002] Desk lamps and flashlights are two widely used lighting products in daily office, home, and outdoor settings, but their functional positioning differs significantly: desk lamps focus on providing wide-area, uniform illumination, suitable for static scenarios such as reading and writing on a desktop; flashlights focus on directional, focused illumination, suitable for mobile lighting, emergency lighting, and other scenarios. Traditionally, desk lamps and flashlights are separate products, requiring users to purchase and store them separately.

[0003] Currently, in order to integrate the functions of both desk lamps and flashlights, some dual-purpose lighting devices have emerged in existing technology, achieving switching between the two working modes through structures such as folding lamp bodies and flipping lamp heads. However, after long-term use and verification, existing dual-purpose lighting devices still have some technical shortcomings:

[0004] 1. It is difficult to balance the storage capacity and stability of the supporting structure. Some dual-purpose lamps use fixed lamp posts, which are bulky and have poor portability and storage capabilities.

[0005] 2. Poor dual-mode adaptability of the light-emitting components. Existing solutions mostly use a single light source with different optical structures to achieve mode switching, making it difficult to simultaneously guarantee the illumination breadth of the desk lamp mode and the focused light intensity of the flashlight mode.

[0006] This invention is based on the above circumstances. Summary of the Invention

[0007] This invention overcomes the shortcomings of the prior art and provides a lighting device with both flashlight and desk lamp modes.

[0008] This invention is achieved through the following technical solution:

[0009] A lighting device with flashlight and desk lamp modes includes a base, a light-emitting component, and an electronic control component. A switching structure is provided between the light-emitting component and the base to allow the lighting device to switch between desk lamp and flashlight modes. The switching structure includes a support rod slidably connected to the base and capable of extending from the top of the base or retracting into the base. The top of the support rod is connected to the light-emitting component. A limiting structure is provided between the support rod and the base to restrict the sliding of the support rod relative to the base when the lighting device is in desk lamp mode. The light-emitting component includes a first light-emitting part and a second light-emitting part, both of which are equipped with light sources. A first hinge structure is provided between the first and second light-emitting parts to allow them to rotate relative to each other, enabling the backlight sides of both parts to open and close.

[0010] As described above, a lighting device with a flashlight mode and a desk lamp mode is provided. The base is provided with a sliding groove with an open upper end. The support rod is slidably assembled in the sliding groove. The limiting structure includes an elastic block provided at the lower part of the support rod. The groove wall is provided with a limiting hole for the elastic block to be inserted when the support rod slides to a preset position.

[0011] As described above, a lighting device with a flashlight mode and a desk lamp mode is provided with a guide inclined surface at the lower part of the elastic block; when the downward pressure applied to the support rod exceeds a preset value, the wall of the limiting hole moves along the guide inclined surface, pushing the elastic block to exit the limiting hole radially, thereby releasing the sliding limit between the support rod and the base.

[0012] As described above, a lighting device having a flashlight mode and a desk lamp mode is provided, wherein a second hinge structure is provided between the first light-emitting part and the support rod to allow the two to rotate and connect, and the upper end of the base is provided with an embedding groove. When the lighting device is in flashlight mode, the light-emitting side of the first light-emitting part is embedded in the embedding groove.

[0013] As described above, a lighting device with a flashlight mode and a desk lamp mode is provided at the upper end of the base, which is connected to the open end of the slide groove so that the support rod can rotate around the axis of the limiting hole by a first preset angle.

[0014] As described above, a lighting device having a flashlight mode and a desk lamp mode, wherein the second hinge structure is disposed inside the first light-emitting part, and the lower end of the first light-emitting part is provided with a second clearance opening that allows it to rotate relative to the support rod by a second preset angle.

[0015] As described above, a lighting device having a flashlight mode and a desk lamp mode includes an electronic control component comprising a control circuit board disposed inside the base, a rechargeable battery electrically connected to the control circuit board, and a switch disposed on the outer wall of the base.

[0016] As described above, a lighting device with a flashlight mode and a desk lamp mode is provided on the outer wall of the base, which also has a charging input interface and a power output interface that are electrically connected to a rechargeable battery.

[0017] As described above, a lighting device with flashlight mode and desk lamp mode is provided with a charging indicator light electrically connected to the control circuit board on the outer wall of the base.

[0018] As described above, a lighting device having a flashlight mode and a desk lamp mode is provided with a support block extending from the outer wall of the base at the lower part of the base.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The first and second light-emitting parts of this invention are each independently equipped with a light source, and the backlight side is opened and closed relative to each other through the first hinge structure. In the unfolded state, the two light-emitting parts are arranged at a certain angle, and the light-emitting side can cover a wider lighting area to meet the reading and writing lighting needs of the desk lamp mode. When the support rod is retracted into the base, the device relies on the second light-emitting part to provide directional lighting, thereby switching to the flashlight mode.

[0021] The support rod, which slides with the base, serves as the switching support structure. In table lamp mode, the support rod extends upward and is locked in the sliding position by a limiting structure, which can stably support the light-emitting component and prevent accidental retraction during use. In flashlight mode, the support rod can be completely stored inside the base, significantly reducing the overall size of the device, making it easy to hold and carry when going out, with outstanding storage and portability.

[0030] The present invention will now be further described with reference to the accompanying drawings:

[0031] like Figures 1 to 7The lighting device shown includes a base 1, a light-emitting component 2, and an electronic control component 3. A switching structure 4 is provided between the light-emitting component 2 and the base 1 to allow the lighting device to switch between the desk lamp mode and the flashlight mode. The switching structure 4 includes a support rod 41 that is slidably connected to the base 1 and can extend from the top of the base 1 or be stored in the base 1. The top of the support rod 41 is connected to the light-emitting component 2. A limiting structure 5 is provided between the support rod 41 and the base 1 to restrict the sliding of the support rod 41 relative to the base 1 when the lighting device is in the desk lamp mode. The light-emitting component 2 includes a first light-emitting part 21 and a second light-emitting part 22. Both the first light-emitting part 21 and the second light-emitting part 22 are provided with a light source 23. A first hinge structure 6 is provided between the first light-emitting part 21 and the second light-emitting part 22 to allow them to rotate relative to each other, so as to realize the mutual opening and closing of the backlight side of the two.

[0032] The first light-emitting part 21 and the second light-emitting part 22 of this invention are each independently equipped with a light source 23, and the backlight side is opened and closed relative to each other through the first hinge structure 6. In the unfolded state, the two light-emitting parts are arranged at a certain angle, and the light-emitting side can cover a wider illumination area to meet the reading and writing illumination needs of the desk lamp mode. When the support rod 41 is stored back into the base 1, the device relies on the second light-emitting part 22 for directional illumination, thereby switching to flashlight mode. The support rod 41, which slides with the base 1, is used as the switching support structure. In the desk lamp mode, the support rod 41 extends upward and is locked in the sliding position by the limiting structure 5, which can stably support the light-emitting component 2 and prevent accidental retraction during use. In the flashlight mode, the support rod 41 can be completely stored inside the base 1, which significantly reduces the size of the whole device, making it easy to hold and carry when going out, and its storage and portability are outstanding.

[0033] Furthermore, the base 1 is provided with an open upper groove 11, the support rod 41 is slidably assembled in the groove 11, the limiting structure 5 includes an elastic block 51 provided at the lower part of the support rod 41, and the groove wall of the groove 11 is provided with a limiting hole 52 for the elastic block 51 to be inserted when the support rod 41 slides to a preset position.

[0034] No separate locking button is required; the limiting structure 5 is fully integrated into the support rod 41 and the slide groove 11. This reduces the number of parts, simplifies processing and assembly, and effectively lowers the overall manufacturing cost. When the support rod 41 slides upward to the preset working height of the desk lamp, the elastic block 51 automatically engages in the limiting hole 52, forming a stable axial limiting constraint. This effectively restricts the sliding of the support rod 41 relative to the base 1, preventing the support rod 41 from unexpectedly retracting due to external force or vibration during desk lamp mode.

[0035] Furthermore, the lower part of the elastic block 51 is provided with a guide inclined surface 53; when the downward pressure on the support rod 41 exceeds a preset value, the wall of the limiting hole 52 moves along the guide inclined surface 53, pushing the elastic block 51 radially out of the limiting hole 52, thereby releasing the sliding limit between the support rod 41 and the base 1. By providing a guide inclined surface 53 at the lower part of the elastic block 51, the axial downward pressure borne by the support rod 41 can be decomposed into a radial pushing force. There is no need to configure an external unlocking button. The user only needs to press down on the support 41 directly, and the wall of the limiting hole 52 can slide along the guide inclined surface 53 and push the elastic block 51 radially retract, automatically releasing the axial limit. The storage action of the support rod 41 is completed in one step, greatly simplifying the operation process of switching from table lamp mode to flashlight mode, and providing a smooth and intuitive user experience.

[0036] Specifically, the bottom of the support rod 41 is provided with an elastic sleeve, the elastic block 51 is provided on the elastic sleeve, and the elastic sleeve is provided with a cut to facilitate its deformation.

[0037] In some embodiments, a second hinge structure 7 is provided between the first light-emitting part 21 and the support rod 41 to allow them to rotate and connect. The upper end of the base 1 is provided with an embedding groove 12. When the lighting device is in flashlight mode, the light-emitting side of the first light-emitting part 21 is embedded in the embedding groove 12, which can form a stable position constraint on the first light-emitting part 21 in flashlight mode, avoiding the problem of loosening, swaying, and random rotation after storage. At the same time, after storage, the first light-emitting part 21 and the base 1 fit together as one, and the overall outline of the device is flat without any protruding structure, which not only greatly improves the handheld grip comfort in flashlight mode, but also ensures the compactness and portability of the overall structure.

[0038] Furthermore, the sidewall of the embedding groove 12 is provided with a protrusion for restricting the light-emitting side of the first light-emitting part 21 from dislodging.

[0039] The first hinge structure 6 and the second hinge structure 7 described above are common connection structures in the art and will not be described in detail further. Furthermore, the first hinge structure 6 uses its own damping to maintain the adjustable angle of the first light-emitting part 21 and the second light-emitting part 22.

[0040] In some embodiments, the second light-emitting part 22 is provided with a light-concentrating cover 231 and a light-concentrating lens 232 that can focus the light of its light source 23.

[0041] In some embodiments, the upper end of the base 1 is provided with a first clearance opening 13 that communicates with the open end of the slide groove 11, thereby allowing the support rod 41 to rotate around the axis of the limiting hole 52 by a first preset angle. In desk lamp mode, after the support rod 41 extends and is axially locked, it can tilt and swing around the axis of the limiting hole 52 within the first preset angle range defined by the first clearance opening 13. This, combined with the hinge angle adjustment of the light-emitting component 2 itself, allows the first light-emitting part 21 and the second light-emitting part 22 to be in a better lighting position. In one embodiment, the rotation angle of the support rod 41 after rotation relative to its vertically upward position is 15° to 45°.

[0042] Furthermore, the second hinge structure 7 is disposed inside the first light-emitting part 21. The lower end of the first light-emitting part 21 is provided with a second clearance opening 211 that allows it to rotate relative to the support rod 41 by a second preset angle, thereby enabling fine adjustment of the light emission direction of the first light-emitting part 21. When the rotation angle of the support rod 41 relative to its vertically upward position is 15° to 45°, the first light-emitting part 21 can still be kept horizontal.

[0043] In some embodiments, the base 1 is provided with a jog switch that can control the opening and closing of the light source 23 of the first light-emitting part 21. When the support rod 41 retracts into the slide groove 11, the support rod 41 presses the jog switch to turn off the light source 23 of the first light-emitting part 21. When the support rod 41 extends out of the slide groove 11 and is in table lamp mode, the light source 23 of the first light-emitting part 21 is connected to the control circuit of the switch 33 and is controlled by the switch 33.

[0044] In some embodiments, the lower part of the base 1 is provided with a support block 8 that can extend from the outer wall of the base 1, so that the base 1 can be placed more stably. In flashlight mode, the support block 8 can be retracted into the base 1.

[0045] In some embodiments, the electronic control component 3 includes a control circuit board 31 disposed inside the base 1, a rechargeable battery 32 electrically connected to the control circuit board 31, and a switch 33 disposed on the outer wall of the base 1. Furthermore, multiple brightness levels and light on / off states can be achieved by pressing the switch a certain number of times.

[0046] In some embodiments, the outer wall of the base 1 is further provided with a charging input interface 34 and a power output interface 35 that are electrically connected to the rechargeable battery 32. The outer wall of the base 1 is also provided with a charging indicator light 36 that is electrically connected to the control circuit board 31. The charging input interface 34 is a USB charging interface, and the power output interface 35 is a TYPE-C external power output interface.

[0047] In some embodiments, the lower part of the base 1 is further provided with a rope-tying part 9 for tying a rope.
