Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting, in particular to a lamp. BACKGROUND

[0002] At present, the realization of the anti-pulling performance of the lamp wire is mostly through setting a wire clamp or a wire tail structure on the wire, and then fixing a U-shaped plastic piece on the shell of the lamp through a fastener such as a screw bolt, so as to press and fix the wire through the U-shaped plastic piece. The wire and the U-shaped plastic piece can also be engaged and fixed through a sawtooth structure, so that the wire can have good anti-pulling performance. However, this method needs to additionally process a wire clamp or a wire tail structure on the wire, and the processing procedure is complex and the assembly efficiency is low.

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.

[0029] The lamp will be described in detail through specific embodiments as follows:

[0030] Referring to Figures 1 to 5 Some embodiments of the present application provide a lamp, which comprises a shell 1, a light source plate 2 and a connecting line 3.

[0031] The light source plate 2 is arranged in the inside of the shell 1, the first through hole 21 and the second through hole 22 are arranged on the light source plate 2, one end of the connecting wire 3 is bent and passes through the first through hole 21 from one side of the light source plate 2 to the other side of the light source plate 2, the part of the connecting wire 3 passing through the light source plate 2 is bent again and passes back through the second through hole 22 from the other side of the light source plate 2 and is connected with the light source plate 2, and the other end of the connecting wire 3 passes out of the shell 1.

[0032] That is, part of the connecting wire 3 is located in the inside of the shell 1, part of the connecting wire 3 is located in the outside of the shell 1, and the end of the connecting wire 3 located in the inside of the shell 1 passes through the first through hole 21 and the second through hole 22 on the light source plate 2 in sequence before being connected with the light source plate 2. In this way, the connecting wire 3 can be wound on the light source plate 2, and when the connecting wire 3 has a tendency to come out due to tension, the side walls of the first through hole 21 and the second through hole 22 can exert an anti-extrusion force on the connecting wire 3.

[0033] Further, the connecting wire 3 needs to pass through the second through hole 22 and the first through hole 21 in reverse in sequence before it can be completely pulled out, the extrusion path of the connecting wire 3 is relatively complex, which can further improve the anti-pulling performance, so that the connecting wire 3 can be stably connected with the light source plate 2. The lamp of the present application does not need additional wire clamping or wire tail structure, only needs to arrange the first through hole 21 and the second through hole 22 on the light source plate 2, which can meet the anti-pulling requirement of the connecting wire 3, and the structure is simple and convenient to install.

[0034] In some embodiments, referring to Figure 2 and Figure 3 , the connecting wire 3 comprises a main body part 31, a bending part 32 and a connecting part 33 connected in sequence.

[0035] In specific implementation, the connecting part 33 is connected with the light source plate 2, part of the main body part 31 is located in the inside of the shell 1, and the other part of the main body part 31 is located in the outside of the shell 1, that is, the main body part 31 can pass through the shell 1, the main body part 31 located in the inside of the shell 1 and the connecting part 33 are located on one side of the light source plate 2, the two ends of the bending part 32 pass through the first through hole 21 and the second through hole 22 respectively and are bently connected with the main body part 31 and the connecting part 33 respectively, and the rest of the bending part 32 is located on the other side of the light source plate 2.

[0036] That is, referring to Figure 1 and Figure 2 , the middle part of the bending part 32 is located on the other side of the light source plate 2 away from the main body part 31 and the connecting part 33, one end of the bending part 32 is bent and passes through the first through hole 21 and can be connected with the main body part 31, the other end of the bending part 32 is bent and passes through the second through hole 22 and can be connected with the connecting part 33, so that the bending part 32 can pass through the light source plate 2 twice and the side walls of the first through hole 21 and the second through hole 22 can exert an anti-extrusion force on the bending part 32.

[0037] Specifically, referring to Figure 3 As shown in the figure, the bending part 32 is formed in a U-shaped bending structure to adapt to the first through hole 21 and the second through hole 22, and passes through the light source plate 2 through the first through hole 21 and the second through hole 22, so that the connecting line 3 can be wound on the light source plate 2, and the anti-pulling performance of the connecting line 3 is improved.

[0038] In some embodiments, referring to Figure 2 and Figure 4 As shown in the figure, the light source plate 2 is fixed on the inner bottom wall of the shell 1, and the inner bottom wall of the shell 1 is recessed to form an avoiding groove 11. One end of the connecting line 3 is located on the side of the light source plate 2 facing the inner bottom wall of the shell 1 and is located in the avoiding groove 11, so that the part of the connecting line 3 protruding from the light source plate 2 can be avoided through the avoiding groove 11. In this way, when the light source plate 2 is arranged on the inner bottom wall of the shell 1, a large gap can be avoided between the light source plate 2 and the inner bottom wall of the shell 1, and the internal space of the shell 1 can be fully utilized.

[0039] Referring to Figure 4 As shown in the figure, the inner wall of the avoiding groove 11 is coated with a glue layer 111, and the part of the connecting line 3 located in the avoiding groove 11 is bonded to the avoiding groove 11 through the glue layer 111. Specifically, when the light source plate 2 is fixed on the inner wall of the shell 1, the connecting line 3 located on the side of the light source plate 2 facing the inner bottom wall of the shell 1 can press the glue layer 111, so that the glue layer 111 can be uniformly distributed during the pressing process, and the connecting line 3 can be bonded to the inner wall of the avoiding groove 11 through the glue layer 111, which can improve the connection stability between the connecting line 3 and the shell 1, and further improve the anti-pulling performance of the connecting line 3 to further ensure the connection stability of the connecting line 3 and the light source plate 2.

[0040] In specific implementation, the glue can be directly dripped into the avoiding groove 11, and the glue can be uniformly dispersed to form the glue layer 111 during the process of the connecting line 3 entering the avoiding groove 11, so as to realize the bonding of the connecting line 3 and the avoiding groove 11, which is simple in operation and convenient to install.

[0041] Further, referring to Figure 4 As shown in the figure, part of the inner wall of the avoiding groove 11 expands away from the inside of the avoiding groove 11 to form a glue overflow groove 112, and the glue overflow groove 112 communicates with the avoiding groove 11.

[0042] It can be understood that the avoiding groove 11 is adapted to the connecting line 3 located on the side of the light source plate 2 facing the inner bottom wall of the shell 1, so that the connecting line 3 can be bonded to the inner wall of the avoiding groove 11, thereby meeting the anti-pulling requirement of the connecting line 3.

[0043] It should be noted that the glue is easy to overflow the avoiding groove 11, by setting the glue overflow prevention groove 112 on the inner wall surface of the avoiding groove 11, the excess glue can enter the glue overflow prevention groove 112, so the setting can not only limit the connecting line 3 on the inner wall surface of the avoiding groove 11, but also avoid the glue overflow affecting the installation of the light source plate 2.

[0044] Specifically, referring to Figure 4 , the glue overflow prevention groove 112 is arranged at the top of the end of the avoiding groove 11, so that the glue can be evenly distributed on the inner wall surface of the avoiding groove 11, avoiding the glue from entering the glue overflow prevention groove 112 too much, and further ensuring the bonding performance between the connecting line 3 and the avoiding groove 11. Of course, it should be noted that the glue overflow prevention groove 112 can also be arranged at other positions of the avoiding groove 11, and the present application does not limit this, which can be arranged according to actual needs.

[0045] In some embodiments, referring to Figure 4 , the avoiding groove 11 is formed as a wedge-shaped groove, which gradually shrinks from the slot opening to the slot bottom of the avoiding groove 11. That is, the size of the avoiding groove 11 gradually decreases from the slot opening to the slot bottom of the avoiding groove 11, and further guides the connecting line 3 on the side of the light source plate 2 towards the inner bottom wall of the shell 1 to gradually enter the avoiding groove 11.

[0046] Specifically, the inner side wall and the inner bottom wall of the avoiding groove 11 form an included angle greater than 90°, when the connecting line 3 is located in the avoiding groove 11, the connecting line 3 can be prevented from being excessively bent, and at the same time, the connecting line 3 and the inner wall surface of the avoiding groove 11 have a larger contact area, thereby increasing the bonding performance between the connecting line 3 and the inner wall surface of the avoiding groove 11, and improving the anti-pulling performance of the connecting line 3.

[0047] In some embodiments, referring to Figure 5 , the outer side of the part of the connecting line 3 passing through the first through hole 21 and the second through hole 22 is covered with a protective sleeve 4, so as to protect the connecting line 3 by the protective sleeve 4, and avoid the first through hole 21 and the second through hole 22 from colliding or damaging the connecting line 3 when the connecting line 3 is pulled due to stress.

[0048] In specific implementation, the protective sleeve 4 is in interference fit with the inner wall of the first through hole 21 and the inner wall of the second through hole 22, so as to increase the friction between the protective sleeve 4 and the inner wall of the first through hole 21 and the inner wall of the second through hole 22, and further improve the anti-pulling performance of the connecting line 3. It can be understood that even if the protective sleeve 4 and the inner wall of the first through hole 21 and the inner wall of the second through hole 22 are in abutment and interact with each other, the connecting line 3 arranged in the protective sleeve 4 can still be prevented from being damaged when the connecting line 3 is pulled, and the lamp can have high anti-pulling performance and safety performance, and also have a long service life.

[0049] In some embodiments, referring to Figure 1 and Figure 4 , a through hole 12 is formed in the side wall of the shell 1, and the other end of the connecting line 3 passes out of the shell 1 through the through hole 12. The outer side of the part of the connecting line 3 passing through the through hole 12 is covered with a protective sleeve 4, so as to prevent the connecting line 3 from being bumped or damaged by the through hole 12 when the connecting line 3 is pulled under stress.

[0050] In specific implementation, referring to Figure 2 and Figure 5 , the protective sleeve 4 is at least correspondingly sleeved on the outer side of the part of the connecting line 3 extending from the through hole 12 to the first through hole 21 and the second through hole 22, and the protective sleeve 4 can complete the protection of multiple positions at one time.

[0051] In some embodiments, the protective sleeve 4 is a heat-shrinkable tube. It can be understood that the heat-shrinkable tube can shrink after being heated. When the protective sleeve 4 is installed, the protective sleeve 4 can be tightly sleeved on the connecting line 3 by heating, which is convenient to install, and can also prevent the relative movement between the connecting line 3 and the protective sleeve 4, so as to fix the position of the connecting line 3 relative to the light source board 2 and improve the anti-pulling performance of the connecting line 3.

[0052] In some embodiments, a limiting buckle 13 is arranged on the inner side wall of the shell 1, and the light source board 2 is limited between the inner bottom wall of the shell 1 and the limiting buckle 13. Specifically, the number of the limiting buckle 13 is multiple, the multiple limiting buckles 13 are located at the same height of the inner side wall of the shell 1, and the multiple limiting buckles 13 are arranged at intervals to jointly apply a limiting force to the light source board 2, so as to fix the light source board 2 inside the shell 1 and prevent the light source board 2 from coming out.

[0053] In specific implementation, the limiting buckle 13 includes a buckle seat and a buckle arm. The buckle seat is arranged on the inner side wall of the shell 1, the top of the buckle arm is connected with the buckle seat, the bottom of the buckle arm can move towards or away from the inner side wall of the shell 1 relative to the buckle seat, and the side surface of the buckle arm away from the inner side wall of the shell 1 is formed as an inclined surface which gradually inclines to the central axis of the shell 1 in the direction in which the light source board 2 is loaded into the shell 1.

[0054] In the installation process of the light source plate 2, the inclined surface can guide the light source plate 2 to pass over the clamping arm, so that the light source plate 2 can be limited between the inner bottom wall of the shell 1 and the clamping arm, so that the light source plate 2 can be fixed inside the shell 1.

[0055] Of course, it should be pointed out that the limiting buckle 13 can also be other forms of structure, and the present application does not make any limitation, as long as the light source plate 2 can be limited between the inner bottom wall of the shell 1 and the limiting buckle 13, so as to realize the installation and fixation of the light source plate 2.
