The reflective sheet 130 is stacked on the back plate 110, and the reflective sheet 130 is provided with a locking inlet 131 and a locking opening 132 connected to the locking inlet 131. The base 121 is disposed through the locking entrance 131, the base 121 is locked between the reflective sheet 130 and the back plate 110, and the supporting portion 122 is locked in the locking opening 132. During assembly, one end of the base 121 is moved into the locking entrance 131, and then the base 121 is pushed to be locked between the reflective sheet 130 and the back plate 110. The substrate 121 may be pushed to be clamped between the reflective sheet 130 and the back plate 110 along a direction forming an included angle with the surface of the back plate 110, or the substrate 121 may be pushed to be clamped between the reflective sheet 130 and the back plate 110 along a direction parallel to the surface of the back plate 110.

Preferably, the surface of the supporting portion 122 abuts or abuts against the latching surface 1340 of the latching portion 134 for limiting the position of the supporting portion 122. Specifically, in some embodiments, the distance between the two latching surfaces 1340 is smaller than the thickness of the supporting portion 122 along a plane parallel to the plate surface of the back plate 110, so that the surface of the supporting portion abuts against the latching surfaces 1340 of the latching portions 134, or the distance between the two latching surfaces 1340 is equal to the thickness of the supporting portion 122, so that the surface of the supporting portion and the latching surfaces 1340 of the latching portions 134 are attached to each other. The two engaging portions 134 of the same group are oppositely applied to the supporting portion 122 along the first direction in a plane parallel to the plate surface of the back plate 110, so that the mounting stability of the lamp supporting member 120 is improved.
As shown in fig. 2 and 4, in some embodiments, the blocking surfaces 1340 include a first blocking surface 1341 and a second blocking surface 1342 connected to the first blocking surface 1341, the first blocking surface 1341 is connected to the insertion surface 1345, and the second blocking surface 1342 extends to be connected to the main body 133, so that after the supporting portion 122 enters the blocking opening 132, the supporting portion passes through between two first blocking surfaces 1341 in the same group, and then is located between two second blocking surfaces 1342 in the same group. In a plane parallel to the plate surface of the back plate 110, the interval range between the first blocking surfaces 1341 of the two blocking portions 134 in the same group is smaller than the thickness of the supporting portion 122, and the interval range between the second blocking surfaces 1342 is equal to the thickness of the supporting portion 122, so that when the supporting portion 122 is located between the two second blocking surfaces 1342 in the same group, the surface of the supporting portion 122 is attached to the second blocking surfaces 1342. A transition surface 1343 is further disposed between the first blocking surface 1341 and the second blocking surface 1342, the second blocking surface 1342 extends to be connected with the main body 133, the length of the second blocking surface 1342 can be adjusted, two opposite sides of the support portion 122 are respectively attached to the main body 133 and the transition surface 1343, and therefore in a plane parallel to the surface of the backboard 110, the two blocking portions 134 and the main body 133 in the same group can act on the support portion 122 from a direction perpendicular to the first direction, so that the main body 133 and the blocking portions 134 can act on the support portion 122 in multiple directions to improve the installation stability of the lamp support member 120. First screens face 1341, second screens face 1342 and transition face 1343 can all be set as the plane, first screens face 1341 and second screens face 1342 can parallel arrangement, transition face 1343 sets up with second screens face 1342 is perpendicular, conveniently along same direction propelling movement lamp support piece 120 until support portion 122 card locate between two second screens faces 1342 of same group, rethread transition face 1343, two second screens faces 1342 and main part 133 surface limit support portion 122's position.
In some embodiments, the latching portion 134 may be integrally disposed with the main body portion 133, so as to ensure the connection structural strength between the latching portion 134 and the main body portion 133, and improve the latching stability of the latching portion 134 and the main body portion 133 to the lamp support 120.
After the base 121 of the lamp supporting member 120 needs to penetrate the position-locking entrance 131 of the reflector 130, the supporting portion 122 is locked between the two position-locking portions 134 of the same group, and the structure of the position-locking portion 134 near the position-locking entrance 131 will affect the installation efficiency of the lamp supporting member 120. The orientation of the card access 131 can be changed by designing a space between the end of the card portion 134 adjacent to the inserting surface 1345 and the back plate 110, so as to facilitate the base 121 to quickly enter between the card portion 134 and the back plate 110 from the card access 131.
As shown in fig. 2 and 5, in some embodiments, the position-locking portion 134 may be convex, and in a direction perpendicular to the surface of the back plate 110, there is a space between the position-locking portion 134 and the back plate 110, and the space is equal to the thickness of the base 121, and a surface of the position-locking portion 134 opposite to the position-locking surface 1340 and the inserting surface 1345 extends to be connected to the main body 133, so that the base 121 can be inserted directly between the position-locking portion 134 and the back plate 110 from the position-locking entrance 131, and the base 121 can move between the position-locking portion 134 and the back plate 110 to adjust the position of the lamp supporting member 120.

The reflective sheet 130 is a deformable reflective sheet 130, and when the base 121 of the lamp supporting member 120 is clamped between the clamping portion 134 and the back plate 110, the clamping portion 134 can act on the base 121 under the action of the elastic deformation, so that the base 121 abuts against the back plate 110, thereby improving the mounting stability of the lamp supporting member 120 on the back plate 110. When the reflection sheet 130 is manufactured, the locking entrance 131 and the locking opening 132 can be cut out from the corresponding position of the reflection sheet 130 directly, so that the locking portion 134 and the main body 133 are integrally formed, thereby facilitating the processing of the reflection sheet 130.
The difficulty of the base 121 being clamped between the retaining portion 134 and the back plate 110 is increased to prevent the retaining portion 134 from being attached to the back plate 110. As shown in fig. 6, in some embodiments, a guiding flange 1346 is disposed at an end of the detent 134 adjacent to the detent entrance 131, the guiding flange 1346 extends in a direction away from the back plate 110, and the insertion surface 1345 is disposed on the guiding flange 1346. After the position on the reflector 130 is cut out to form the card-locking entrance 131 and the card-locking opening 132, further, the card-locking part 134 is pressed with a guiding flange 1346, so that a space exists between the inserting surface 1345 and the back plate 110 in a direction perpendicular to the surface of the back plate 110, the base 121 is conveniently clamped between the inserting surface 1345 and the back plate 110 (i.e. between the card-locking part 134 and the back plate 110), the installation of the base 121 is guided, and the installation efficiency of the lamp supporting member 120 is improved.

The length of the positioning opening 132 is greater than or equal to the length of the base 121, so that the positioning portion 134 can be adjusted to limit the position of the supporting portion 122 from multiple directions, thereby improving the installation stability of the lamp supporting member 120.
The base 121 is a plate-shaped base 121, which facilitates the movement of the base 121 between the position-locking portion 134 and the back plate 110 along a direction parallel to the surface of the back plate 110. The supporting portion 122 is disposed on the base 121, so that the projection of the center of gravity of the supporting portion 122 on the plate-shaped base 121 and the structure of the supporting portion 122 overlapped with the center of the plate-shaped base 121 can be applied to the present application, so as to ensure the installation stability of the lamp supporting member 120 on the back plate 110. For example, the supporting portion 122 may be provided as a plate-like or cylindrical structure having a cross section that uniformly decreases in a direction away from the base 121.
