For example, connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two components or an interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0036] The light box in the existing technology usually fixes the LED light strip in the U-shaped profile base groove, and then pushes the optical light guide plate into the U-shaped profile base. The various components are arranged in sequence to form an assembly structure. In this way, when quality problems occur in the light box, more complicated disassembly is required to obtain the LED light strip, which leads to problems such as inconvenient maintenance, high maintenance costs, and high professional requirements for maintenance personnel.

[0037] The following is a preferred embodiment of a light bar and light box that is convenient to maintain and can solve the above technical problems, provided by the present invention.

[0038] Please refer to Figure 1-Figure 4 In the figures, units with similar structures are represented by the same reference numerals.

[0039] The utility model provides a light bar light box with convenient maintenance, which comprises: a base 12, an upper cover 1, an LED light bar, a light guide plate 5, a reflective paper 7, and a surface cover 3.

[0040] Among them, multiple bases 12 are enclosed to form a frame structure and an installation groove 123. The installation groove 123 is sequentially arranged with reflective paper 7, a light guide plate 5, and a surface cover 3 from bottom to top. Each base 12 is rotatably connected to a top cover 1, and the top cover 1 includes an extension plate 101. The LED light strip is arranged on the extension plate 101.

[0041] The upper cover 1 rotates in a closed position and an open position. When in the closed position, the upper cover 1 seals the gap between the top cover 3 and the base 12. The extension plate 101 is located within the mounting groove 123, and the LED light strip emits light toward the side of the light guide plate 5, forming a tightly sealed structure. When the upper cover 1 is in the open position, the gap between the top cover 3 and the base 12 is exposed, and the LED light strip faces the space outside the mounting groove 123, making it very easy to repair the LED light strip and reducing maintenance costs.

[0042] Please refer to Figure 3 Specifically, a connecting portion 121 is provided on the side of the base 12 close to the upper cover 1, a rotating shaft 1211 is provided on the side of the connecting portion 121 away from the mounting groove 123, and a connecting groove 103 is provided on one side of the upper cover 1, which wraps the rotating shaft 1211 and forms a rotational fit.

[0043] The light bar light box with convenient maintenance in this embodiment also includes an elastic member 2. A first limiting groove 1212 is provided on one side of the connecting portion 121 near the mounting groove 123. The extension plate 101 is connected to the upper cover 1 via the connecting plate 102. A second limiting groove 104 is formed between the connecting plate 102 and the upper cover 1. One end of the elastic member 2 is limited within the first limiting groove 1212, and as the upper cover 1 rotates, the elastic member 2 has a certain amount of movable space within the first limiting groove 1212. The other end of the elastic member 2 is limited within the second limiting groove 104, and as the upper cover 1 rotates, the elastic member 2 has a certain amount of movable space within the second limiting groove 104. The elastic member 2 is used to keep the upper cover 1 in the closed position or the open position.

[0044] Please refer to Figure 3 and Figure 5 In this embodiment, the elastic member 2 includes a main section 201 and an elastic section 202. The main section 201 is a straight bar structure, with elastic sections 202 connected to both ends of the main section 201. The elastic sections 202 are curved bar structures, and both elastic sections 202 bend and extend toward the center of the main section 201. The main section 201 is restrained in the first restraining groove 1212, and the end of the elastic section 202 away from the main section 201 is restrained in the second restraining groove 104. The elastic member 2 has a low structural cost and good elastic force.

[0045] It is understandable that the elastic member 2 may be provided at a plurality of positions between the upper cover 1 and the base 12 to enable the upper cover 1 to stably rotate to the open position or the closed position.

[0046] Furthermore, the elastic member 2 can also include a connecting section 203, which is connected to the end of the elastic section 202 away from the main section 201. The connecting section 203 is a curved bar structure, and the convex side of the connecting section 203 contacts the inner wall surface of the second limiting groove 104, so that during the rotation of the upper cover 1, the connecting section 203 can form a relative movement with the second limiting groove 104.

[0047] Please refer to Figure 3 In addition, the inner bottom surface of the first limiting groove 1212 is a concave arc surface, and the two inner side surfaces of the first limiting groove 1212 are respectively the first limiting surface and the second limiting surface. Figure 3 In the viewing direction, the left side of the first limiting groove 1212 is the first limiting surface, and the right side is the free limiting surface.

[0048] When the upper cover 1 is in the open position, the main body section 201 contacts the first limiting surface, and in the cross-sectional view of the first limiting groove 1212 (ie Figure 3From the perspective of the present invention, the main section 201, the elastic section 202, and the rotating shaft 1211 form a triangular structure. In this way, the elastic force of the elastic member 2 drives the upper cover 1 to rotate in the direction away from the surface cover 3, and the upper cover 1 is limited and cannot continue to rotate in the direction away from the surface cover 3. Therefore, the upper cover 1 can be stably maintained in the open position.

[0049] When the upper cover 1 is rotated to a set position between the open and closed positions, the main section 201 contacts the concave arc surface, and the main section 201, the elastic section 202, and the rotating shaft 1211 are located on the same plane. That is, as the elastic member 2 moves from the first limiting surface to the direction closer to the second limiting surface during the rotation of the upper cover 1, the elastic force of the elastic member 2 will gradually increase, making it more difficult to move in this direction. On the other hand, when the elastic member 2 moves from the second limiting surface to the direction closer to the first limiting surface, the elastic force of the elastic member 2 will also gradually increase, making it more difficult to move in this direction. This makes it easier for the upper cover to remain in the open or closed position.

[0050] When the upper cover 1 is in the closed position, the main body section 201 contacts the second limiting surface, and in the cross-sectional view of the first limiting groove 1212 (ie Figure 3 From the perspective of the present invention, the main section 201, the elastic section 202, and the rotating shaft 1211 form a triangular structure. In this way, the elastic force of the elastic member 2 drives the upper cover 1 to rotate toward the direction close to the surface cover 3. However, the upper cover 1 is limited by the surface cover 3 and cannot continue to rotate toward the direction close to the surface cover 3. Therefore, the upper cover 1 can be stably maintained in the closed position.

[0051] Please refer to Figure 3 In this embodiment, the circumferential side of the rotating shaft 1211 is connected to the connecting portion 121, and the inner circumference of the connecting groove 103 is smaller than the outer circumference of the rotating shaft 1211. When the upper cover 1 is in the open position, the connection between the rotating shaft 1211 and the connecting portion 121 contacts the edge of the connecting groove 103, thereby forming a rotation limit for the upper cover 1. That is, the connection between the rotating shaft 1211 and the connecting portion 121 can further limit the upper cover 1 from rotating away from the cover 3. When the upper cover 1 is in the closed position, the cover 3 contacts the connecting plate 102, forming a rotation limit for the upper cover 1, and preventing the upper cover 1 from rotating further toward the cover 3.

[0052] Please refer to Figure 3 and Figure 4 In this embodiment, the connecting plate 102 is a bent structure, and the connection position between the connecting plate 102 and the upper cover 1 is a set distance away from the edge of the upper cover 1, so that the edge of the upper cover 1 can be operated to open or close the upper cover 1. When the upper cover 1 is in the closed position, the edge of the upper cover 1 is a set distance away from the surface cover 3.

[0053] Please refer to Figure 1 and Figure 3In this embodiment, the base 12 is provided with an insertion slot 122 along the axial direction. Two adjacent bases 12 are connected by an L-shaped angle bracket 13, which is inserted into the insertion slot 122. The insertion slot 122 also passes through the side of the base 12 away from the connecting portion 121, so that the angle bracket 13 and the base 12 can be fixedly connected using a screw 14.

[0054] The light bar light box with convenient maintenance in this embodiment also includes a light piece 4, which is arranged between the light guide plate 5 and the cover 3. The cover 3 and the light piece 4 work together to ensure that the light is more uniform and comfortable, and the distribution and intensity of the light can be adjusted as needed. The design of the cover 3 facilitates the control of the diffusion range and intensity of the light. The cover 3 can be a plane or a reflective surface with a certain angle, so that the light can be concentrated or dispersed to prevent the light from directly shining into the human eye. At the same time, it can also reduce the scattering of light and make the light more uniform. The light piece 4 is mainly used to filter light, reduce glare, and provide a certain color temperature control. It can adjust the direction and intensity of the light to make the light softer and more uniform, thereby improving the lighting comfort.

[0055] In this embodiment, one side of the reflective paper 7 is bonded to the light guide plate 5 via double-sided tape 6 , the other side of the reflective paper 7 is bonded to the base 12 via double-sided tape 8 , and the LED light strip is bonded to the extension plate 101 via thermal adhesive 9 .

[0056] Please refer to Figure 1 and Figure 6 In this embodiment, the LED light strip includes a first light board module 10 and a second light board module 11. Both ends of the first light board module 10 are provided with positive and negative electrode connection holes 111, and both ends of the second light board module 11 are provided with positive and negative conductive pins 1011 for connecting wires to the positive and negative electrode connection holes 111. This allows the first and second light board modules 10, 11 to be connected or replaced with each other, facilitating partial replacement and maintenance of the LED light strip.

[0057] It should be noted that multiple first light board modules 10 are initially connected into a whole structure, and a cutting line is set between adjacent first light board modules 10. During maintenance and replacement, cutting operations can be performed at the cutting line to remove the partially damaged first light board module 10, and then the second light board module 11 can be used to replace the position connected to the damaged first light board module 10.

[0058] Please refer to Figure 7Specifically, the outer circumferences of the positive and negative conductive pins 1011 are provided with wavy springs 1111, and the inner circumferences of the positive and negative connection holes 111 are provided with wavy convex and concave portions 1012 that mate with the springs 1111. The springs 1111 are elastic and fit tightly against the positive and negative conductive pins 1011 when plugged in. The wavy structure ensures a tighter connection between the two, preventing them from loosening or falling off, while also increasing the conductive area and preventing poor contact.

[0059] Please refer to Figure 2 and Figure 4 In this embodiment, the light bar light box for easy maintenance further includes a spring wire 15, which passes through the base 12 and extends into the mounting groove 123 and is connected to the LED light bar. The spring wire 15 is used to electrically connect the LED light bar to the power supply.

[0060] The working principle of this utility model is as follows: When the LED light strip is damaged, simply apply force to the upper cover 1 to tilt it to the open position. The elastic force of the elastic member 2 will keep the upper cover 1 in the open position, with the LED light strip facing the space outside the mounting slot 123, making it very convenient to repair the LED light strip. After the repair is complete, apply force to drive the upper cover 1 to the closed position. The elastic force of the elastic member 2 will keep the upper cover 1 in the closed position. The entire operation is very convenient and requires minimal professional expertise from the maintenance personnel.

[0061] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
