Description

Technical Field

[0001] The present disclosure relates to a lamp clip and its application, and more particularly to a lamp clip with an adjustable clamping member and its application. Background Art

[0002] Traditional lighting fixtures, such as pendant lights, recessed lights, and table lamps, are often fixed and bulky. When users only need localized lighting or enhanced illumination, such as for a monitor screen (such as a desktop or laptop), they typically use a fixture that can be fixed to the screen, placing the light source adjacent to the monitor screen.

[0003] Currently, there are lamps on the market that can be fixed to screens. For example, a lamp is fixed using a clamp, and the entire structural weight is supported by the clamp. One end of the clamp is clamped to the (upper) edge of the screen, and the other end holds the lamp. Because the clamp is clamped between the monitor's screen frame and screen back panel with two opposing surfaces, with the design trend of gradually narrowing screen frames, the clamp's clamping area is compressed, making it possible for traditional clamps to provide sufficient clamping force to firmly fix the lamp. Coupled with the emergence of curved screens and ultra-thin screens, how to provide a stable clamping function for the lamp in response to the frame design of different types of screens, while taking into account the overall aesthetics and integrity of the clamp, has become a major issue in this technical field.

[0004] Therefore, there is a need to provide an advanced lamp clip and its application to solve the problems faced by the prior art. Summary of the Invention

[0032] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0033] This specification provides a lamp clamp and its application. The clamping distance or the distance between the light source and the object can be adjusted according to the user's operational requirements, thereby improving ease of use and reliability. To facilitate understanding of the aforementioned embodiments and other purposes, features, and advantages of this specification, several preferred embodiments are described below with accompanying drawings for detailed explanation.

[0034] However, it must be noted that these specific implementation cases and methods are not intended to limit the present invention. The present invention may still be implemented using other features, components, methods, and parameters. The preferred embodiments are merely intended to illustrate the technical features of the present invention and are not intended to limit the scope of the present invention. A person skilled in the art will be able to make equivalent modifications and changes based on the description below without departing from the spirit of the present invention. In different embodiments and figures, the same elements will be represented by the same element symbols.

[0035] Please refer to Figure 1A and Figure 1B , Figure 1A A structural perspective view of a lamp 10 according to an embodiment of this specification; Figure 1A Draw application Figure 1A A schematic cross-sectional view of the structure of a lamp clip 100 in the lamp 10. Figure 1A As shown, the lamp 10 is a lighting device that uses a lamp clip 100 to fix a light source 11 on an object 12 to provide local lighting to the object 12 .

[0036] In some embodiments of this specification, object 12 may be a display screen, a bookcase, a desk, a nightstand, a workbench, or other device or hardware requiring localized lighting. In this embodiment, object 12 is a display screen, and light source 11 may be a lamp tube secured to a lamp clip 100. The combination of lamp clip 100 and light source 11 forms a lamp 10 that can be selectively clamped to the upper edge of display 12.

[0037] The lamp clamp 100 includes a first clamping member 101 and a second clamping member 102. The first clamping member 101 includes a light source fixing portion 101A, a connecting portion 101B, and a stop portion 101C. The light source fixing portion 101A is used to fix the light source 11. The connecting portion 101B is connected to the light source fixing portion 101A. The stop portion 101C is movably connected to the connecting portion 101B and has a stop surface 101C1 that can be selectively fixed to one of a plurality of positions on the connecting portion 101B. The second clamping member 102 is connected to the connecting portion 101B to clamp the object 12 between the stop surface 101C1 of the stop portion 101C of the first clamping member 101 and the second clamping member 102.

[0038] In some embodiments of this specification, the light source fixing portion 101A includes a C-shaped elastic clip, and the light source 11 is clamped in the C-shaped elastic clip. In this embodiment, one end of the C-shaped elastic clip of the light source fixing portion 101A is directly connected to the connecting portion 101B in an integral manner. However, the connection method between the light source fixing portion 101A and the connecting portion 101B is not limited to this. In other embodiments of this specification, the C-shaped elastic clip of the light source fixing portion 101A can be movably connected to the connecting portion 101B via a slot, a slide rail, or other movable connection member (not shown).

[0039] In some embodiments of the present disclosure, the second clamping member 102 includes a pivot 102a, a clamping portion 102b, and a counterweight 102c. The pivot 102a extends through the connection point between the second clamping member 102 and the connecting portion 101B, pivotally connecting the clamping portion 102b to the connecting portion 101B, thereby allowing the clamping portion 102b to flexibly rotate about the pivot 102a. Furthermore, the counterweight 102c is located within the clamping portion 102b. When gravity acts on the counterweight 102c, it generates a clockwise torque relative to the pivot 102a. The light source 11, together with the first clamping member 101, generates a counterclockwise torque relative to the pivot 102a. These two torques drive the stopper 101C of the first clamping member 101 and the second clamping member 102 toward each other, pressing against the object 12 and generating a clamping force to hold the object 12. In this embodiment, the stopper 101C of the first clamping member 101 can press against the upper edge 12a of the display surface of the display (object 12), while the second clamping member 102 can press against the back surface 12b of the display.

[0040] The stopper portion 101C of the first clamping member 101 includes a first retaining wall 103 and a second retaining wall 104. The first retaining wall 103 protrudes from the first position 101B1 of the connecting portion 101B and has a first surface 103a facing the second clamping member 102. The second retaining wall 104 is detachably connected to the connecting portion 101B and extends to a second position 101B2 of the connecting portion 101B. It also has a second surface 104a facing the second clamping member 102. The second surface 104a of the second retaining wall 104 is closer to the pivot 102a of the second clamping member 102 than the first surface 103a of the first retaining wall 103.

[0041] Specifically, the second retaining wall 104 may be a housing. When the housing of the second retaining wall 104 is detachably attached to the first retaining wall 103, the second surface 104a is located at the second position 101B2 of the connecting portion 101B and can function as the stop surface 101C1 of the stop portion 101C, thereby clamping the display (object 12) together with the second clamping member 102. When the housing of the second retaining wall 104 is removed from the first retaining wall 103, the first surface 103a of the first retaining wall 103, located at (corresponding to) the first position 101B1 of the connecting portion 101B, can function as the stop surface 101C1 of the stop portion 101C, thereby clamping the display (object 12) together with the second clamping member 102.

[0042] When the stop surface 101C1 is at the first position 101B1 of the connection portion 101B, the distance between the stop surface 101C1 (the first surface 103a of the first retaining wall 103) and the pivot 102a of the second clamping member 102 is distance H11. When the stop surface 101C1 is at the second position 101B2, the distance between the stop surface 101C1 (the second surface 104a of the second retaining wall 104) and the pivot 102a of the second clamping member 102 is distance H12. Distance H11 is greater than distance H12. By selecting either the first retaining wall 103 or the second retaining wall 104 as the stop surface 101C1 of the stop portion 101C, the lamp clip 100 can be adapted for displays (objects 12) of varying thicknesses.

[0043] Furthermore, without changing the thickness of the display (object 12) and allowing the second clamping member 102 to pivot freely, when the stop surface 101C1 is in the first position 101B1, the distance between the location where the stop surface 101C1 (the first surface 103a of the first retaining wall 103) contacts the display surface (the upper edge 12a of the display surface) and the light source 11 is distance S11. When the stop surface 101C1 is in the second position 101B2, the distance between the location where the stop surface 101C1 (the second surface 104a of the second retaining wall 104) contacts the display surface (the upper edge 12a of the display surface) and the light source 11 is distance S12. Distance S12 is greater than distance S11. By selecting either the first retaining wall 103 or the second retaining wall 104 as the stop surface 101C1 of the stop portion 101C of the first clamping member 101, the distance between the display surface and the light source 11 can be adjusted.

[0044] Please refer to Figure 2A and Figure 2B , Figure 2A and Figure 2B According to another embodiment of the present disclosure, partial perspective views of the structure of the lamp 20 in different operating states are respectively shown. The structure of the lamp 20 is substantially similar to that of the lamp 10, except that the structure of the first clamping member 201 of the lamp 20 is different.

[0045] In this embodiment, the lamp 20 uses a lamp clamp 200 to fix the light source (not shown) on the display (not shown). The lamp clamp 200 includes: a first clamping member 201 and a second clamping member 202. The first clamping member 201 includes: a light source fixing portion 201A, a connecting portion 201B and a stop portion 201C. The stop portion 201C of the first clamping member 201 includes: a first retaining wall 203 and a second retaining wall 204. The first retaining wall 203 is protruded from the first position 201B1 of the connecting portion 201B, and has a fixed surface 203a facing the second clamping member 202. The second retaining wall 204 is rotatably connected to the connecting portion 201B, and has a first surface 204a and a second surface 204b located on the opposite side. When the second retaining wall 204 is in the first rotation position (such as Figure 2A As shown in FIG, the first surface 204a is coplanar with the fixed surface 203a; when the second retaining wall 204 is located at the second rotation position (as shown in FIG, Figure 2B As shown in FIG. 2 , the second surface 204b faces the second clamping member 202 and is closer to the pivot 202a of the second clamping member 202 than the first surface 204a.

[0046] Specifically, the stopper portion 201C of the first clamping member 201 includes a rotating disk 205 pivotally connected to the connecting portion 201B. The rotating disk 205 has a rotating surface 205a perpendicular to the extension direction Z of the first retaining wall 203. The second retaining wall 204 is parallel to the extension direction Z of the first retaining wall 203 and protrudes from the edge of the rotating surface 205a. The first surface 204a of the second retaining wall 204 is flat and parallel to the fixed surface 203a of the first retaining wall 203; the second surface 204b of the second retaining wall 204 is an arcuate surface.

[0047] When the rotating disk 205 is rotated so that the second retaining wall 204 is located at the first rotating position (such as Figure 2A When the second retaining wall 204 is engaged with the first retaining wall 203 (as shown), the second retaining wall 204 can be engaged with the first retaining wall 203. At this point, the first surface 204a of the second retaining wall 204 is coplanar with the fixing surface 203a of the first retaining wall 203, located at (corresponding to) the first position 201B1 of the connecting portion 201B, and facing the second clamping member 202. The first surface 203a of the first retaining wall 203 and the first surface 204a of the second retaining wall 204 can serve as the stop surface 201C1 of the stop portion 201C, and together with the second clamping member 202, clamp a display (not shown).

[0048] When the rotating disk 205 is rotated so that the second retaining wall 204 is located at the second rotation position (such as Figure 2B(as shown), the second retaining wall 204 is away from the first retaining wall 203. At this point, the second surface 204b of the second retaining wall 204 is located at (corresponding to) the second position 201B2 of the connecting portion 201B and faces the second clamping member 202. The second surface 204b of the second retaining wall 204 can serve as the stop surface 201C1 of the stop portion 201C, and together with the second clamping member 202, clamps a display (not shown).

[0049] When the stop surface 201C1 is at the first position 201B1 of the connection portion 201B, the distance between the stop surface 201C1 (the first surface 204a and the fixed surface 203a of the first retaining wall 203) and the pivot 202a of the second clamping member 202 is distance H21. When the stop surface 201C1 is at the second position 201B2, the distance between the stop surface 201C1 (the second surface 204b of the second retaining wall 204) and the pivot 202a of the second clamping member 202 is distance H22. Distance H21 is greater than distance H22. By rotating the dial 205 to select either the first retaining wall 204a or the second retaining wall 204b of the second retaining wall 204 as the stop surface 201C1 of the stop portion 201C, the lamp clip 200 can be adapted to displays (objects 12) of varying thicknesses.

[0050] Furthermore, without changing the thickness of the display and allowing the second clamping member 202 to pivot freely, when the stop surface 201C1 is in the first position 201B1, the distance between the location where the stop surface 201C1 (the first surface 204a of the second retaining wall 204) contacts the display surface (not shown) and the light source (represented by the center point of the light source fixing portion 201A) is distance S21. When the stop surface 201C1 is in the second position 201B2, the distance between the location where the stop surface 201C1 (the second surface 204a of the second retaining wall 204) contacts the display surface (not shown) and the light source is distance S22. Distance S22 is greater than distance S21. By rotating the dial 205 to select either the first retaining wall 204a or the second retaining wall 204b of the second retaining wall 204 as the stop surface 201C of the stop portion 201C, the distance between the display surface (not shown) and the light source can be adjusted.

[0051] Please refer to Figure 3A and Figure 3C , Figure 3A and Figure 3B According to another embodiment of the present specification, partial structural perspective views of the lamp 30 in different operating states are respectively illustrated. Figure 3C according to Figure 3B The illustrated portion is a side view of the structure of the lamp 30. The structure of the lamp 30 is similar to that of the lamp 10, except that the structure of the first clamping member 301 of the lamp 30 is different.

[0052] In this embodiment, the lamp 30 uses a lamp clamp 300 to secure a light source (not shown) to a display (not shown). The lamp clamp 300 includes a first clamping member 301 and a second clamping member 302. The first clamping member 301 includes a light source securing portion 301A, a connecting portion 301B, and a stopper 301C. The stopper 301C of the first clamping member 301 includes a slider 303 and a retaining wall 304. The slider 303 is slidably connected to the connecting portion 301B. The retaining wall 304 protrudes from a surface 303a of the slider 303 and has a retaining surface 304a perpendicular to the surface 303a of the slider 303, facing the second clamping member 302.

[0053] Specifically, the connecting portion 301B has a guide groove 305 parallel to the long axis L of the connecting portion 301B for accommodating the slider 303. In this embodiment, the slider 303 has a bottom surface 303b located on the side opposite to the surface 303a, and the bottom surface 303b faces the bottom 305b of the guide groove 305. The guide groove 305 has a guide groove 305a parallel to the long axis L of the connecting portion 301B (see FIG. Figure 3A and Figure 3B ), and the guide groove 305a is connected to the guide rail 303c (see Figure 3C ) are interlocked with each other, so that the slider 303 can be slidably set in the sliding groove 305, thereby driving the retaining wall 304 to move at multiple positions (such as the first position 301B1 and the second position 301B2) in the direction of the long axis L of the parallel connection part 301B.

[0054] When the retaining wall 304 is moved to the first position 301B1 of the connecting portion 301B (eg Figure 3A When the retaining wall 304 is moved to the second position 301B2 of the connecting portion 301B (as shown in FIG. 1 ), the retaining surface 304a of the retaining wall 304 faces the second clamping member 302 and clamps the display (not shown) together with the second clamping member 302. At this time, the distance between the retaining surface 304a and the pivot 302a of the second clamping member 302 is a distance H31. Figure 3B When the lamp clamp 300 is positioned (as shown), the stop surface 304a of the retaining wall 304 faces the second clamping member 302 and, together with the second clamping member 302, clamps the display (not shown). At this point, the distance between the stop surface 304a and the pivot axis 302a of the second clamping member 302 is distance H32. Distance H31 is greater than distance H32. By sliding the slider 303 to select the position of the stop surface 304a, the lamp clamp 300 can be adapted to displays (objects 12) of varying thicknesses.

[0055] Furthermore, without changing the thickness of the display and allowing the second clamping member 302 to pivot freely, when the stop surface 301C1 is located at the first position 301B1 of the connecting portion 301B, the distance between the position where the stop surface 301C1 (304a) contacts the display surface (not shown) of the display and the light source (represented by the center point of the light source fixing portion 201A) is distance S31. When the stop surface 301C1 is located at the second position 301B2 of the connecting portion 301B, the distance between the upper edge of the display surface (not shown) of the display and the light source is distance S32. Distance S32 is greater than distance S31. The distance between the display surface and the light source is adjusted by sliding the slider 303 to select the position of the stop surface 304a.

[0056] In addition, in some embodiments, the slide groove 305 also includes a plurality of recessed chambers 305c recessed in the bottom 305b of the slide groove 305; at the same time, the slider 303 also has at least one (preferably multiple) protrusions 303d protruding from the bottom surface 303b of the slider 303, and engaging with at least one of the plurality of recessed chambers 305c to fix the stop surface 304a at the first position 301B1 or the second position 301B2 of the connecting portion 301B.

[0057] Based on the above embodiments, the present disclosure provides a lamp clamp and its application, comprising two clamping members for securing a lamp source to an object. At least one of the two clamping members has a movable stopper that is movably connected to the corresponding clamping member in a non-elastic reciprocating manner to provide a secure clamping force, thereby securing the lamp source to the object.

[0058] Furthermore, by adjusting the position of the stopper, the clamping distance between the two clamping members can be flexibly adjusted to accommodate objects of varying shapes or thicknesses. Alternatively, without changing the shape or thickness of the clamped object, the distance between the clamped object and the light source can be adjusted by adjusting the position of the stopper. Therefore, the clamping distance or the distance between the light source and the object can be varied to meet user needs without affecting the structural integrity and aesthetics of the lamp clamp, improving ease of use and reliability.

[0059] The present invention has been described with reference to the above embodiments. However, the above embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements that do not depart from the spirit and scope of the present invention are intended to be protected by the present invention.
