However, a single light source cannot simultaneously meet the different brightness requirements of the central area and the edge area.

If local high brightness is required, LED beads need to be densely arranged, resulting in large thickness and high power consumption. If strip light structure and tunnel light structure are mechanically combined as a combined light source, there will be physical gaps or optical transition discontinuities in the light-emitting surface of the combined light source. This will cause a sudden drop in brightness in the seam area of ​​the light-emitting surface of the combined light source, affecting the inspection effect. Utility Model Content

[0029] Please see Figures 1 to 6This utility model provides a combined light source device for strip light and tunnel light, which includes a housing 300 and a light source component. The housing 300 is provided with a first light outlet 310, a mounting port 320, and a first receiving space 330. The mounting port 320 is located at the top of the housing 300 and communicates with the first receiving space 330. The first light outlet 310 is located at the bottom of the housing 300 and communicates with the first receiving space 330. The mounting port 320 and the first light outlet 310 are arranged opposite each other in the vertical direction. The light source assembly includes a first light source assembly 100 and a second light source assembly 200. The first light source assembly 100 is disposed within a first receiving space 330. The first light source assembly 100 includes a tunnel light source 110 and a reflector 120. The reflector 120 has a reflective surface 123. The reflector 120 has a first end 121 and a second end 122 along its width direction. The first end 121 of the reflector 120 is connected to the wall of the first receiving space 330, and the second end 122 of the reflector 120 is located between the mounting port 320 and the first light outlet 310. The reflective surface 123 of the reflector 120... The first light outlet 310 is positioned towards the first light source 310; the tunnel light source 110 is positioned on the wall of the first accommodating space 330 and facing the reflective surface 123 of the reflector 120; the second light source assembly 200 is positioned at the mounting opening 320 and above the second end 122 of the reflector 120, and is connected to the housing 300; the second light source assembly 200 includes a base 210, a strip light source 220, a diffuser 230, and a mounting plate 240; the base 210 is provided with a second light outlet 211 and a second accommodating space 212; the second light outlet 211 is located on the base 210. The bottom of the base 210 is connected to the second receiving space 212; the light source 220 is disposed in the second receiving space 212 and faces the second light outlet 211; the diffuser plate 230 is disposed at the bottom of the base 210 and covers the second light outlet 211; the mounting plate 240 is disposed between the diffuser plate 230 and the reflector plate 120 and connects the second end 122 of the diffuser plate 230 and the reflector plate 120; the diffuser plate 230 and the second end 122 of the reflector plate 120 are at least partially disposed opposite each other in the vertical direction, and are disposed opposite to the first light outlet 310 in the vertical direction.

[0030] In this embodiment of the invention, the object to be detected can be placed below the first light outlet 310. The reflective surface 123 of the reflector 120 of the first light source assembly 100 is positioned facing downwards from the first light outlet 310, while the tunnel light source 110 is positioned facing the reflector 120. This allows the tunnel light source 110 to illuminate the reflector 120 and the reflective surface 123 of the reflector 120, and then reflect the light back to the first light outlet 310 through the reflector 120, so that the light is emitted from the first light outlet 310. The mounting port 320 is located vertically above the first light outlet 310. The second light source assembly 200 is positioned at the mounting port 320, and the second light outlet 211 is located below the base 210. The strip light source 220 is positioned facing the second light outlet 211, so that the strip light source 220 can illuminate the diffuser 230 and then illuminate the first light outlet 310, so that the light is emitted from the first light outlet 310.

[0031] The reflective surface 123 of the reflector 120 facing the first light outlet 310 is the light-emitting surface of the first light source assembly 100, and the lower end surface of the diffuser 230 is the light-emitting surface of the second light source assembly 200. The diffuser 230 and the second end 122 of the reflector 120 are at least partially arranged opposite each other in the vertical direction, and are also arranged opposite to the first light outlet 310 in the vertical direction, so that the light-emitting surface of the first light source assembly 100 and the light-emitting surface of the second light source assembly 200 can be continuously and seamlessly connected. The brightness of the joint area between the light-emitting surfaces of the first light source assembly 100 and the second light source assembly 200 is high, ensuring the detection effect.

[0032] Specifically, the mounting plate 240 is located between the reflector plate 120 and the diffuser plate 230 to prevent the mounting plate 240 from blocking the light emitted by the tunnel light source 110. The end of the second end 122 of the reflector plate 120 extends below the diffuser plate 230, so that the diffuser plate 230 and the second end 122 of the reflector plate 120 are at least partially vertically opposite each other. The light source 220 emits light and reflects it through the reflector plate 120, while the light emitted by the tunnel light source 110 is transmitted through the diffuser plate 230. Thus, in the vertical direction, the end of the second end 122 of the reflector plate 120 and the diffuser plate 230 are continuously connected, thereby achieving a seamless connection of the light-emitting surfaces.

[0033] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the length direction of the first light source component 100 and the length direction of the second light source component 200 are both the first horizontal direction; two light source components are provided and are symmetrically arranged with respect to the second horizontal direction; the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0034] The length direction of the first light source assembly 100 extends along the first horizontal direction to increase the size of the light-emitting surface of the first light source assembly 100 and ensure the detection effect; the length direction of the second light source assembly 200 extends along the first horizontal direction to increase the size of the light-emitting surface of the second light source assembly 200 and ensure the detection effect.

[0035] The light source component has two parts, which can improve the detection effect. The first horizontal direction and the second horizontal direction are arranged perpendicular to each other, so that the second light source components 200 of the two light source components are arranged adjacent to each other to improve the illumination brightness. The first light source components 100 of the two light source components are located on both sides along the second horizontal direction to improve the uniformity of illumination.

[0036] Specifically, the second light source components are arranged adjacent to each other, while the first light source components are arranged at intervals.

[0037] Reference Figure 3 In some embodiments of this utility model, the bases 210 of the second light source components 200 of the two light source components are spaced apart to ensure heat dissipation and to allow observation of the object to be detected below the first light outlet 310 through the gap between the two second light source components 200, thereby improving the convenience of use.

[0038] Reference Figure 3 In some embodiments of this utility model, the second light source assembly 200 further includes a reflective strip 250, which is disposed on the side wall of the second accommodating space 212.

[0039] By setting reflective strips 250, the light can be collected, reducing the degree of light decay emitted by the tunnel light source 110 in the second accommodating space 212, thereby improving the brightness effect.

[0040] Specifically, the reflective strip 250 extends along the first horizontal direction and covers the sidewalls of the second receiving space 212 to ensure light collection effect.

[0041] Reference Figure 3 In some embodiments of this utility model, two reflective strips 250 are provided, and are respectively provided on the opposite side walls of the second accommodating space 212 along the second horizontal direction.

[0042] Since the length direction of the second light source assembly 200 is the first horizontal direction, the side wall area of ​​the second accommodating space 212 is relatively large. By setting two reflective strips 250 along the second horizontal direction, the light collection effect can be further guaranteed.

[0043] Reference Figure 3In some embodiments of this utility model, the tunnel light source 110 is disposed on the top wall of the second accommodating space 212. When the light emitted by the tunnel light source 110 shines on the side wall of the second accommodating space 212, the side wall of the second accommodating space 212 away from the reflector 120 is an inclined surface that is inclined downward, so that a reflection effect can be achieved.

[0044] Specifically, a reflective strip 250 is provided on the side wall of the second accommodating space 212. By setting an inclined surface that is inclined downward, the reflective strip 250 can also be inclined downward, thereby further improving the light collection effect.

[0045] Reference Figure 1 and Figure 4 In some embodiments of this utility model, a first cooling fan 410 and a heat sink 420 are also included; a heat dissipation port 340 is provided on the outer casing 300, the heat sink 420 is provided on the wall surface of the outer casing 300, and the first cooling fan 410 is provided at the heat dissipation port 340 and is positioned towards the heat sink 420.

[0046] Since the light source 220 is located on the inner wall of the first accommodating space 330, the heat dissipation efficiency of the outer casing 300 can be improved by setting the heat sink 420 on the inner wall surface of the first accommodating space 330. The heat dissipation port 340 on the outer casing 300 connects the first accommodating space 330 and the outside, so that the first cooling fan 410 can blow airflow onto the heat sink 420 to further improve the heat dissipation effect.

[0047] Specifically, multiple heat sinks 420 are provided, and the multiple heat sinks 420 are arranged sequentially at intervals along the second horizontal direction. Multiple first cooling fans 410 are provided, and the multiple first cooling fans 410 are arranged along the first horizontal direction, and all of them are located above the multiple heat sinks 420, so as to further improve the heat dissipation efficiency.

[0048] Reference Figure 1 and Figure 3 In some embodiments of this utility model, a second cooling fan 510 is also included; a heat dissipation groove 213 is provided on the top of the base 210, and multiple heat dissipation grooves 213 are provided and all extend in the first horizontal direction, and the multiple heat dissipation grooves 213 are arranged in sequence at intervals along the second horizontal direction; the second cooling fan 510 is provided on the top of the base 210 and is located above the multiple heat dissipation grooves 213; the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0049] The heat dissipation slot 213 is located on the top of the base 210. By setting the heat dissipation slot 213, the heat dissipation efficiency of the outer shell 300 can be improved. The first cooling fan 410 blows airflow into the heat dissipation slot 213 to further improve the heat dissipation effect.

[0050] Specifically, multiple heat dissipation slots 213 are provided, and the multiple heat dissipation slots 213 are arranged sequentially at intervals along the second horizontal direction. Multiple second cooling fans 510 are provided, and the multiple second cooling fans 510 are arranged along the first horizontal direction, and are all located above the multiple heat dissipation slots 213, so as to further improve the heat dissipation efficiency.

[0051] Reference Figure 3 and Figure 6 In some embodiments of this utility model, the reflector 120 is recessed in a direction away from the first light outlet 310 to ensure the effect of reflecting light.

[0052] In some embodiments of this utility model, the second light source assembly 200 further includes a connector, a connecting hole is provided on the base 210, a first through hole is provided on the diffuser plate 230, and a second through hole is provided on the mounting plate 240. The connector passes through the second through hole, the first through hole, and the connecting hole, and connects the mounting plate 240, the diffuser plate 230, and the base 210.

[0053] By setting up connectors, the stability of the connection can be improved, so that the mounting plate 240 and the diffuser plate 230 can be fixedly installed on the base 210 in sequence.

[0054] Specifically, the second through hole, the first through hole, and the connecting hole can all be threaded hole structures, and the connector can be a screw or other threaded connection structure to improve the stability of installation and the convenience of installation and disassembly.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
