Those skilled in the art will recognize that equivalent modifications and variations can be made in light of the following description without departing from the spirit of the invention. Like elements in different embodiments and drawings will be denoted by like reference numerals.

Referring to fig. 1A and fig. 1B, fig. 1A is a perspective view illustrating a structure of a lamp 10 according to an embodiment of the present disclosure; fig. 1A is a schematic cross-sectional view illustrating a lamp clip 100 applied to the lamp 10 of fig. 1A. As shown in fig. 1A, the lamp 10 is a lighting device that uses a lamp clip 100 to fix a lamp source 11 on an object 12 for providing local illumination to the object 12.

In some embodiments of the present description, the article 12 may be a display screen, a bookcase, a desk, a bedside table, a work table, or other device or hardware requiring localized illumination. In this embodiment. The object 12 is a screen of a display, the light source 11 can be a lamp tube held in the lamp holder 100, and the combination of the lamp holder 100 and the light source 11 can form a lamp 10 for selectively holding on the upper edge of the display 12.

Wherein lamp clip 100 includes: a first clamping member 101 and a second clamping member 102. A first clamp 101 comprising: a lamp source fixing part 101A, a connecting part 101B and a stopper 101C. The lamp fixing portion 101A is used to fix the lamp 11. The connection portion 101B is connected to the lamp source fixing portion 101A. The stopper 101C is movably connected to the connecting portion 101B and has a stopping surface 101C1 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 for clamping the object 12 between the stopping surface 101C1 of the stopping portion 101C of the first clamping member 101 and the second clamping member 102.

In some embodiments of the present disclosure, the lamp fixing portion 101A includes a C-shaped elastic clip, and the lamp 11 is clamped in the C-shaped elastic clip. In this embodiment, one end of the C-shaped elastic clip of the lamp source fixing portion 101A is directly connected to the connecting portion 101B in an integrally formed manner. However, the connection mode between the lamp source fixing portion 101A and the connection portion 101B is not limited thereto. In other embodiments of the present disclosure, the C-shaped elastic clip of the light source fixing portion 101A may be movably connected to the connecting portion 101B by a slot, a slide rail, or other movable connecting members (not shown).

In some embodiments of the present description, second clamp 102 includes a pivot 102a, a clamp portion 102b, and a weight 102 c. The pivot 102a is disposed through a connection point between the second clamping member 102 and the connection portion 101B, and pivotally connects the clamping portion 102B to the connection portion 101B, so that the clamping portion 102B can movably rotate around the pivot 102 a. In addition, the weight block 102C is located in the clamping portion 102b, when the weight block 102C is acted by gravity, a clockwise moment is generated relative to the pivot 102a, the lamp source 11 and the first clamping member 101 generate a counterclockwise moment relative to the pivot 102a, and the stopping portion 101C of the first clamping member 101 and the second clamping member 102 are close to each other and abut against the object 12 by the driving of the two moment drives, so as to form a clamping force for clamping the object 12.

When the housing of the second retaining wall 104 is detached 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 be used as the stopping surface 101C1 of the stopping portion 101C to clamp the display (object 12) together with the second clamping member 102.

When the stopper surface 101C1 is located at the connecting portion 101B first position 101B1, the distance between the stopper surface 101C1 (the first surface 103a of the first retaining wall 103) and the pivot 102a of the second retainer 102 is a distance H11; when the stopping surface 101C1 is located at the second position 101B2, the distance between the stopping surface 101C1 (the second surface 104a of the second stopper wall 104) and the pivot 102a of the second clip 102 is a distance H12. Wherein distance H11 is greater than distance H12. By selecting the first retaining wall 103 or the second retaining wall 104 as the stopping surface 101C1 of the stopping portion 101C, the lamp clip 100 can be applied to displays (objects 12) with different thicknesses.

In addition, on the premise that the thickness of the display (the object 12) is not changed and the second clamping piece 102 is freely pivoted, when the stopping surface 101C1 is located at the first position 101B1, the distance between the position where the stopping surface 101C1 (the first surface 103a of the first retaining wall 103) touches the display surface (the upper edge 12a of the display surface) and the light source 11 is the distance S11; when the stopping surface 101C1 is located at the second position 101B2, the distance between the position (the upper edge 12a of the display surface) where the stopping surface 101C1 (the second surface 104a of the second blocking wall 104) touches the display surface and the light source 11 is the distance S12. Wherein the distance S12 is greater than the distance S11.
