[0027] Please see Figures 1 to 6This utility model provides a synergistic lighting composite light source device, which includes an AOI light source assembly 100, a parallel coaxial light source assembly 200, and a strip light source assembly 300. The AOI light source assembly 100 includes a housing 110 and an annular light-emitting element 120. The housing 110 is provided with a first receiving cavity 111 that extends vertically. Multiple annular light-emitting elements 120 are provided and arranged sequentially along the vertical direction on the inner wall of the first receiving cavity 111, and all of them are inclined downwards. The parallel coaxial light source assembly 200 includes a base 210, a beam splitter 220, and a point light source 230. The base 210 is provided with a first opening 211 and a second receiving cavity 212. The base 210 is located at the top of the housing 110, and the first opening... 211 is disposed at the bottom end of the base 210 and communicates with the second receiving cavity 212, and is disposed opposite to the upper end of the first receiving cavity 111; the beam splitter 220 is obliquely disposed in the second receiving cavity 212 and is located above the first opening 211; the light-emitting end of the point light source 230 is located in the second receiving cavity 212 and is disposed towards the beam splitter 220; the strip light source assembly 300 includes a frame 310 and a strip light-emitting element 320; the top end of the frame 310 is connected to the bottom end of the outer shell 110; the strip light-emitting element 320 is rotatably disposed on the side end of the frame 310, and rotating the strip light-emitting element 320 can cause the light-emitting surface 321 of the strip light-emitting element 320 to rotate to be disposed obliquely downward; multiple strip light source assemblies 300 are provided and are arranged at intervals around the vertical direction.

[0028] In this embodiment of the invention, the workpiece to be inspected can be placed below the outer casing 110; a plurality of annular light-emitting elements 120 are provided on the inner wall of the first receiving cavity 111 of the outer casing 110, and the annular light-emitting elements 120 are inclined downward so as to emit light toward the workpiece to be inspected; a base 210 is provided at the top of the outer casing 110, and the light emitted by the point light source 230 in the base 210 illuminates the inclined beam splitter 220. The beam splitter 220 can reflect the light and make the light enter the first cavity from the upper end of the first receiving cavity 111, so that the light can illuminate the workpiece to be inspected; and a frame 310 is connected to the bottom of the outer casing 110, and a strip light-emitting element 32... The 0 is rotatably mounted on the side of the frame 310. Rotating the strip light-emitting element 320 allows the light-emitting surface 321 of the strip light-emitting element 320 to rotate to face downwards, so that the strip light-emitting element 320 can emit light towards the workpiece to be inspected. The strip light-emitting elements 320 of the multiple strip light source assemblies 300 can illuminate the workpiece to be inspected from different positions to improve the adaptability of the lighting. This collaborative lighting composite light source device can emit light to the workpiece to be inspected through the ring light-emitting element 120, the point light source 230 and the strip light-emitting element 320, which can meet the different lighting needs of the workpiece to be inspected, has good adaptability, and can shorten the inspection process to improve inspection efficiency.

[0029] In some embodiments of this utility model, a control component is also included; the control component is disposed on the housing 110; the control component is electrically connected to the annular light-emitting element 120, the point light source 230 and the strip light-emitting element 320, and is capable of controlling the annular light-emitting element 120, the point light source 230 and the strip light-emitting element 320 to open and close independently.

[0030] When performing illumination inspection on a workpiece with various surface defects, the control unit can independently start and stop the ring light source 120, the point light source 230, and the strip light source 320. This allows the ring light source 120, the point light source 230, and the strip light source 320 to illuminate the workpiece at different times, reducing the mutual interference between the light emitted by the ring light source 120, the point light source 230, and the strip light source 320, thus improving the illumination effect.

[0031] Specifically, the control unit can control multiple ring-shaped light-emitting elements 120 to open and close independently; wherein, the multiple ring-shaped light-emitting elements 120 can be respectively a red-white mixed dual-color light-emitting structure, a blue light-emitting structure, and a blue-white mixed dual-color light-emitting structure.

[0032] Reference Figure 3 In some embodiments of this utility model, the distance between the annular light-emitting element 120 and the vertical axis gradually increases along the vertically downward direction, so as to reduce the degree of mutual obstruction between the multiple annular light-emitting elements 120.

[0034] Reference Figure 3 In some embodiments of this utility model, the angle between the annular light-emitting element 120 and the horizontal plane gradually increases along the vertically downward direction, so that the angles of the light emitted by the multiple annular light-emitting elements 120 are not equal and can be concentrated to illuminate the same position, so as to ensure the lighting effect.

[0035] Specifically, there are three annular light-emitting elements 120. The upper annular light-emitting element 120 has an angle of 30° with the horizontal plane, the middle annular light-emitting element 120 has an angle of 45° with the horizontal plane, and the lower annular light-emitting element 120 has an angle of 70° with the horizontal plane.

[0039] Specifically, the point light source 230 extends at least partially into the second cavity from the mounting port 213, allowing the point light source 230 to move back and forth at the mounting port 213. Limiting bosses are provided along the length of the point light source 230. When the point light source 230 moves back and forth to a predetermined position, one of the limiting bosses of the point light source 230 abuts against the base 210 to limit the position of the point light source 230.

After rotating multiple strip light-emitting elements 320, the light-emitting surface 321 of the strip light-emitting element 320 can be positioned facing downwards towards the inclined first cavity. The housing 110 is provided with an insertion hole, and the top part of the frame 310 can be inserted into the insertion hole. Both the strip light-emitting element 320 and the frame 310 are located below the housing 110 to avoid being positioned below the first cavity, thereby reducing the obstruction of the light emitted by the strip light source assembly 300 to the light emitted by the ring light-emitting element 120 and the point light source 230.

After the strip light-emitting element 320 rotates to the predetermined position, the connector 340 passes through the arc groove 312 and the connecting hole 323 to fix the frame 310 and the strip light-emitting element 320 together, thereby improving the stability of the strip light-emitting element 320 during operation.

[0044] Reference Figures 1 to 3 In some embodiments of this utility model, four strip light source components 300 are provided, wherein two strip light source components 300 are spaced apart along a first horizontal direction, and the other two strip light source components 300 are spaced apart along a second horizontal direction; the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0045] The lighting effect can be further improved by setting up two opposing strip light source components 300.

[0046] Specifically, the four strip light source components 300 are arranged symmetrically in pairs.
