[0035] In order to solve the problem of inconvenient glue filling in the light bar structure in the prior art, the utility model provides a lamp, which comprises a shell and a light bar structure, wherein the light bar structure is arranged inside the shell.

[0036] In this embodiment, one or more light bar structures are provided. When multiple light bar structures are provided, the multiple light bar structures are connected and provided along the second direction.

[0037] Among them, the lamp can be a structural part such as an advertising light box; the light strip structure is a diffuse reflection light strip.

[0038] like Figures 1 to 9 As shown, the light bar structure includes a light board 10, which extends along a first direction. The light bar structure also includes a shell 40, a colloid and an end cover 50. The shell 40 has an installation cavity with a top opening, and the installation cavity extends along the first direction. The light board 10 is installed inside the installation cavity. A glue pouring cavity is formed between the light board 10 and the shell 40. The light-emitting surface of the light board 10 is exposed through the top opening. The end covers 50 are arranged at both ends of the shell 40 along the first direction to block the installation cavity. The end covers 50 have installation grooves 510. At least a portion of the shell 40 and the light board 10 extends into the installation grooves 510. The installation grooves 510 are connected to the glue pouring cavity and have avoidance holes 520 on the top. The avoidance holes 520 are used to avoid the light-emitting surface of the light board 10. The colloid enters the glue pouring cavity through the avoidance holes 520 and the installation grooves 510 to form a glue layer. The light board 10 and the shell 40 are bonded by the glue layer.

[0039] The first direction is the length direction of the light board 10. Figure 1 The width direction of the light board 10 is the second direction, and the second direction is Figure 1 The Y direction shown; the height direction of the light bar structure is Figure 1 The Z direction is shown.

[0040] Specifically, the housing 40 is used to accommodate the lamp board 10 to provide protection; the end caps 50 are disposed at both ends of the housing 40 , so that the overall structure formed by the housing 40 and the lamp board 10 can be connected to the part to be installed, such as the housing of the lamp, through the end caps 50 .

[0041] The housing 40 is an extruded plastic part.

[0042] To facilitate installation of the lamp board 10 , both ends of the housing 40 along the first direction are opened, and the end covers 50 are also used to block the openings at both ends of the housing 40 , thereby improving the stability of installation of the lamp board 10 .

[0043] In the present embodiment, the end cover 50 can not only avoid the light-emitting surface of the lamp board 10 through the setting of the avoidance hole 520, but also facilitate the glue filling operation. The setting of the glue filling cavity structure in the present embodiment is convenient when the lamp board 10 and the outer shell 40 need to be fixed, that is, during the installation process of the lamp board 10, the structure of the avoidance hole 520 on the end cover 50 can avoid the glue filling equipment, thereby avoiding the occurrence of collision. The colloid can flow into the interior of the mounting groove 510 through the avoidance hole 520, and then enter the interior of the glue filling cavity through the mounting groove to achieve bonding and fixation between the lamp board 10 and the outer shell 40. The setting of the glue filling cavity is conducive to providing installation for the glue layer, thereby improving the stability of the installation of the lamp board 10 through the glue layer. The structural setting of the end cover 50 and the glue filling cavity of the light bar structure of the present application facilitates the glue injection operation, simplifies the glue filling process, and improves the efficiency of the installation of the lamp board 10 and the stability of the installation of the lamp board 10.

[0044] Specifically, a groove 401 is provided on the bottom plate of the outer shell 40, and the lamp board 10 is covered at the notch of the groove 401. The lamp board 10 and the groove 401 form a glue filling cavity. The lamp board 10 has a chamfer, and a gap is formed between the chamfer and the outer shell 40. The gap is connected with the groove 401. The colloid enters the interior of the groove 401 through the avoidance hole 520 and the gap to form a glue layer.

[0045] By forming a glue layer inside the groove 401, a stable connection between the lamp board 10 and the housing 40 is achieved, and the avoidance holes 520 and the gap form a flow channel for the colloid filling process to facilitate the smooth flow of the colloid, which is beneficial to improve the filling efficiency.

[0046] The colloid has a heat dissipation function, so that the heat dissipation effect of the lamp panel 10 is improved by setting the colloid.

[0047] like Figure 6 As shown, the bottom plate of the outer shell 40 includes a first support plate segment 410, a bending segment 420 and a second support plate segment 430 which are bent in sequence, and two side walls of the outer shell 40 facing each other are provided with ribs 440, and the two ribs 440 respectively form limiting grooves with the first support plate segment 410 and the second support plate segment 430, and a part of the lamp board 10 is arranged inside the limiting groove.

[0048] The first support plate segment 410 has a first support surface 411, and the second support plate segment 430 has a second support surface 431. The first support surface 411 and the second support surface 431 are used to support the bottom surface of the lamp board 10, and the rib 440 is used to abut against the top surface of the lamp board 10, thereby fixing the lamp board 10 in the height direction of the light strip structure, thereby achieving a stable cover of the lamp board 10 on the notch of the groove 401.

[0049] In this embodiment, a mounting plate section 530 is provided on the side of the end cover 50 facing away from the lamp board 10 along the first direction, and a long hole 531 for fixing is provided on the mounting plate section 530 extending along the first direction. The long hole 531 is used to install the cover plate and the part to be installed, such as the housing of the lamp. The structural setting of the long hole 531 can realize the adjustable position, thereby improving the applicable range of the installation of the end cover 50. The long hole 531 can be a U-shaped hole structure.

[0050] like Figure 7 and Figure 8 As shown, along a second direction perpendicular to the first direction, a clamping structure 540 and a matching structure 550 are provided on both sides of the end cover 50 , and the clamping structure 540 is used to be clamped and fixed with the matching structure 550 of the adjacent light bar structure.

[0051] Among them, one of the snap-fit ​​structure 540 and the matching structure 550 is a protruding structure and the other is a snap-fit ​​groove.

[0052] In this embodiment, when the interior of the lamp is provided with a plurality of light bar structures, the plurality of light bar structures are fixedly connected along the second direction by means of the clamping structure 540 and the matching structure 550 .

[0053] In this embodiment, the protruding structure can be a T-shaped structure, and the slot is adapted to the protruding structure; of course, the protruding structure can also be other structural settings, such as an L-shaped structure, etc., and the specific structure is based on whether the protruding structure can be snap-fitted and fixed inside the slot.

[0054] Figures 1 to 6 As shown, the light bar structure also includes a power box 20 and a wire crimping cover 30, which are arranged on the light board 10, and the power box 20 and the wire crimping cover 30 cooperate to form a cavity 201 for accommodating the power supply 80, and the power box 20 and the wire crimping cover 30 both have a hot pressing column 60, and the hot pressing column 60 is a hollow structure 610 with an open end, and the end of the hot pressing column 60 passes through the light board 10, and the end opening is used for a hot pressing jig to extend into, and the surrounding wall of the end of the hot pressing column 60 is used to be fixed to the light board 10 after hot melting.

[0055] Specifically, the light bar structure of the present application adopts a hot pressing column 60 with a hollow structure 610 set on the power box 20 and the wire crimping cover 30. After the hot pressing column 60 penetrates the lamp board 10, the outer peripheral wall of the end of the hot pressing column 60 is hot-melted to achieve a fixed connection between the end of the hot pressing column 60 and the lamp board 10. Since the present application adopts the hot pressing column 60 with a hollow structure 610, an annular hot melting area will be formed in the process of thermal capacitance connection, which effectively increases the area of ​​the hot pressing connection. By increasing the area of ​​the hot pressing connection, the stability of the connection between the power box 20 and the wire crimping cover 30 is improved.

[0056] Furthermore, the structural arrangement of the hot pressing column 60 of the present application penetrating the lamp board 10 improves the installation accuracy and stability of the power box 20 and the wire crimping cover 30, avoids the phenomenon of the power box 20 and the wire crimping cover 30 being offset, and further improves the installation stability of the power box 20 and the wire crimping cover 30.

[0057] In this embodiment, the light bar structure also includes a light source, which is arranged on the light board 10, wherein the surface of the light board 10 where the light source is located is the light-emitting surface, the power supply 80 is installed on the light-emitting surface, and the power supply 80 is electrically connected to the light source.

[0058] Among them, the light source is LED lamp beads.

[0059] The hot pressing column 60 passes through one end of the lamp board 10 and has an opening on its end, so that when a hot melting operation is required, the hot melting head of the hot pressing jig can be inserted into the hollow structure 610 of the hot pressing column 60, and the heat of the hot pressing jig is used to melt the hot pressing column 60, thereby fixing the hot pressing column 60 to the lamp board 10.

[0060] It can be understood that another function of the hollow structure 610 of the hot pressing column 60 of the present application is to provide positioning for the hot pressing jig. The conical hot melt head of the hot pressing jig is aligned with the center of the hollow structure 610 and extends into it, which is beneficial to improve the accuracy of the hot pressing process.

[0061] In this embodiment, the hot pressing column 60 passes through the light-emitting surface of the lamp board 10 to the back side of the lamp board 10 opposite to the light-emitting surface. The hot pressing fixture will hot-melt the hot pressing column 60 exposed on the back side of the lamp board 10 to achieve a fixed connection between the hot pressing column 60 and the back side of the lamp board 10.

[0062] like Figure 1 and Figure 2 As shown, the power box 20 and the wire pressing cover 30 are spaced apart along a first direction, and both the power box 20 and the wire pressing cover 30 have at least one wiring hole 70 arranged along a second direction perpendicular to the first direction.

[0063] Specifically, one or more wiring holes 70 are provided on the power box 20. When one wiring hole 70 is provided on the power box 20, the wiring hole 70 is preferably provided in the central area of ​​the first direction of the power box 20; when multiple wiring holes 70 are provided on the power box 20, the multiple wiring holes 70 are spaced apart on the power box 20 along the first direction, and the multiple wiring holes 70 are preferably symmetrically arranged with respect to the central area of ​​the first direction of the power box 20.

[0064] One or more wiring holes 70 are provided on the wire crimping cover 30. When one wiring hole 70 is provided on the wire crimping cover 30, the wiring hole 70 is preferably provided in the central area of ​​the wire crimping cover 30 in the first direction; when multiple wiring holes 70 are provided on the wire crimping cover 30, the multiple wiring holes 70 are arranged on the wire crimping cover 30 at intervals along the first direction, and the multiple wiring holes 70 are preferably arranged in a symmetrical structure with respect to the central area of ​​the wire crimping cover 30 in the first direction.

[0065] In this embodiment, the hot pressing columns 60 are arranged at both ends of the power box 20 along the first direction, and the power box 20 is formed into a symmetrical structure. The symmetrically arranged power box 20 can be installed on the light board 10 without distinguishing the direction during the installation of the power box 20, which is conducive to improving the installation efficiency of the power box 20.

[0066] In this embodiment, the hot pressing columns 60 are arranged at both ends of the wire pressing cover 30 along the first direction, and the wire pressing cover 30 is formed into a symmetrical structure. The symmetrically arranged wire pressing cover 30 can be installed on the light board 10 without distinguishing the direction during the installation of the wire pressing cover 30, which is conducive to improving the installation efficiency of the wire pressing cover 30.

[0067] like Figures 1 to 4 As shown, the power box 20 also includes a box body 220, and the side of the box body 220 facing the lamp board 10 has a boss 210 abutting against the lamp board 10, and the hot pressing column 60 is arranged on the end surface of the boss 210 facing the lamp board 10, and the boss 210 has a mounting hole 211 connected to the hollow structure 610 of the hot pressing column 60, and the mounting hole 211 is used for locking with the fastener.

[0068] The boss 210 abuts against the light-emitting surface of the lamp board 10 , and the heat-pressing column 60 is connected to the back side of the lamp board 10 , so as to realize a relatively fixed structure of the power box 20 and the lamp board 10 .

[0069] Specifically, by providing a mounting hole 211 on the boss 210 , it is convenient to use fasteners to connect with the housing of the lamp or other fixing parts. The fasteners can be structural parts such as bolts.

[0070] Furthermore, the diameter of the boss 210 is larger than the diameter of the heat pressing column 60. The lamp board 10 is provided with a via hole, and the heat pressing column 60 penetrates the lamp board 10 through the via hole. The diameter of the boss 210 is larger than the diameters of the heat pressing column 60 and the via hole, so that the boss 210 abuts against the light-emitting surface side of the lamp board 10, and the heat pressing column 60 penetrates the via hole to achieve a hot pressing connection with the back side of the lamp board 10.

[0071] In this embodiment, the hollow structure 610 is a through hole, the aperture of which is smaller than the aperture of the mounting hole 211 , thereby forming an abutment surface in the connecting area between the mounting hole 211 and the through hole to facilitate supporting the fastener through the abutment surface.

[0072] like Figure 5 As shown, the wire crimping cover 30 also includes a cover body 310 abutting against the lamp board 10, and the hot pressing column 60 is arranged on the cover body 310.

[0073] The cover 310 abuts against the light-emitting surface of the lamp board 10 , and the hot pressing column 60 is connected to the back side of the lamp board 10 , so as to realize a relatively fixed structure of the wire pressing cover 30 and the lamp board 10 .

[0074] Specifically, by providing a locking hole 311 on the box body 220, it is convenient to use a locking member to connect with the housing of the lamp or other fixing members. The locking member can be a structural member such as a bolt.

[0075] In this embodiment, the wire pressing cover 30 is used to press on the input wire to prevent people from touching the soldering pad and getting an electric shock, and to prevent the soldered input wire from being pulled out during transportation or installation of the product.

[0076] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0077] The end cap 50 of the light bar structure of the present application can not only avoid the light-emitting surface of the light board 10 through the setting of the avoidance hole 520, but also facilitate the glue filling operation. The setting of the glue filling cavity structure in this embodiment is convenient when the light board 10 and the outer shell 40 need to be fixed, that is, during the installation process of the light board 10, the structure of the avoidance hole 520 on the end cap 50 can avoid the glue filling equipment, thereby avoiding the occurrence of collision. The colloid can flow into the interior of the mounting groove 510 through the avoidance hole 520, and then enter the interior of the glue filling cavity through the mounting groove to achieve bonding and fixation between the light board 10 and the outer shell 40. The setting of the glue filling cavity is conducive to providing installation for the glue layer, and then improving the stability of the installation of the light board 10 through the glue layer. The structural setting of the end cap 50 and the glue filling cavity of the light bar structure of the present application facilitates the glue injection operation, simplifies the glue filling process, and improves the efficiency of the installation of the light board 10 and the stability of the installation of the light board 10.

[0078] The light bar structure of the present application adopts a hot pressing column 60 with a hollow structure 610 set on the power box 20 and the wire crimping cover 30. After the hot pressing column 60 penetrates the light board 10, the outer peripheral wall of the end of the hot pressing column 60 is hot-melted to achieve a fixed connection between the end of the hot pressing column 60 and the light board 10. Since the present application adopts the hot pressing column 60 with a hollow structure 610, an annular hot-melt area will be formed in the process of thermal connection, which effectively increases the area of ​​the hot pressing connection. By increasing the area of ​​the hot pressing connection, the stability of the connection between the power box 20 and the wire crimping cover 30 is improved.

[0079] The structural setting of the hot pressing column 60 of the present application penetrating the lamp board 10 improves the installation accuracy and stability of the power box 20 and the wire crimping cover 30, avoids the phenomenon of deviation of the power box 20 and the wire crimping cover 30, and further improves the installation stability of the power box 20 and the wire crimping cover 30.
