Description

Technical Field

[0001] This utility model relates to the field of LED visual supplement light technology, specifically to a dual-dimensional light source. Background Technology

[0002] In the field of industrial visual inspection, traditional light sources typically provide illumination from only one direction, making it difficult to meet the needs of multi-angle imaging of complex structural components. For example, when inspecting surface pits and protrusions on a product, a single bottom light source may reduce the effective inspection area and cause loss of detail, while a side light source used alone is prone to creating reflections or shadows on flat surfaces, failing to achieve uniform, multi-dimensional integrated illumination. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] In view of this, the present invention provides a dual-dimensional light source that integrates main lighting and auxiliary lighting, which can uniformly illuminate the pits and protrusions on the product surface and coordinate the brightness of the two.

[0005] (II) Technical Solution

[0006] The technical solution adopted by this utility model to solve the above problems is:

[0007] A dual-dimensional light source includes a housing, with a horizontally extending LED light source board at the bottom of the housing, and a light emission port on the side wall adjacent to the LED light source board. A beam splitter for processing the light emitted by the LED light source board is obliquely disposed inside the housing. The housing includes a light transmission port opposite to the light emission port, and an intensifying lens is disposed in the light transmission port. A square frame is disposed around the opening of the housing, and each of the four sides of the frame forms an oblique light source mounting plate. The four oblique light source mounting plates enclose a second light source that gradually expands from the inside of the housing towards the light emission port.

[0008] In the above technical solution, the LED light source board provides the main illumination, the beam splitter is used to change the direction of the main light path, the light-transmitting port provides the supplementary light path, the intensifying lens is used to provide light transmission performance and protect the inside of the box, the tilt angle of the tilted light source mounting plate in the square frame is adjusted according to actual needs, and the second light source provides side illumination to the illuminated object to supplement the lack of main illumination.

[0009] Furthermore, the four tilted light source mounting plates are respectively provided with a first auxiliary light source unit, a second auxiliary light source unit, a third auxiliary light source unit, and a fourth auxiliary light source unit; the brightness of the LED light source board and the first, second, third, and fourth auxiliary light source units can all be adjusted individually.

[0010] In the above technical solution, the first auxiliary light source unit, the second auxiliary light source unit, the third auxiliary light source unit, and the fourth auxiliary light source unit can be adjusted in conjunction with the brightness of the LED light source board, or their brightness can be adjusted individually according to actual needs.

[0011] Furthermore, the light outlet includes a light-diffusing plate and a pressure plate, which cover the second light source and are fixedly mounted on the frame with screws.

[0012] In the above technical solution, the light-diffusing plate and the pressure plate are pressed together by screws and locked onto the frame, thereby fixing the auxiliary light source unit and the heat-conducting pad inside the frame.

[0013] Furthermore, the housing includes a base and a top cover. A front cover, a left cover, and a right cover are vertically connected to the four sides of the base. The top of the front cover, the left cover, and the right cover are all connected to the top cover. The light outlet is located on the side of the base opposite to the front cover.

[0014] Furthermore, both the left and right covers have a beam splitter placement groove on their inner sides, and the two sides of the beam splitter are embedded in the beam splitter placement groove; both the left and right covers have a connecting block on their outer sides, and the connecting block is used to connect external devices.

[0015] In the above technical solution, the beam splitter placement slot is used to fix and install the beam splitter, ensuring that its tilt angle is accurate and stable.

[0016] Furthermore, a light-transmitting opening is provided on the front cover.

The reflective film is set to reflect the stray light from the side wall back, so that it is finally directed to the light outlet. The diffuser is set above the LED light source board and the reflective film to homogenize the light emitted from the LED light source board, so that it is more evenly directed onto the beam splitter and improves the quality of the reflected light.

[0020] Furthermore, the tilted light source mounting plate includes a thermal pad, and the first auxiliary light source unit, the second auxiliary light source unit, the third auxiliary light source unit, and the fourth auxiliary light source unit are all connected to the thermal pad on the tilted surface of the tilted light source mounting plate.

The four oblique light source mounting plates 17 enclose a second light source 5 that gradually expands from the inside of the housing 1 towards the light emission port 3. The four oblique light source mounting plates 17 correspond to... The system includes a first auxiliary light source unit 171, a second auxiliary light source unit 172, a third auxiliary light source unit 173, and a fourth auxiliary light source unit 174. The brightness of the LED light source board 2 and each of the four auxiliary light source units 171, 172, 173, and 174 can be adjusted independently. The tilted light source mounting plate 17 includes a heat-conducting pad 18, and each of the four auxiliary light source units 171, 172, 173, and 174 is connected to the heat-conducting pad 18 on the tilted surface of the tilted light source mounting plate 17. The light outlet 3 includes a light-diffusing plate 6 and a pressure plate 19. The light-diffusing plate 6 and the pressure plate 19 cover the auxiliary light source 5 and are fixedly mounted on the frame 16 with screws. The housing 1 includes a base 12 and a top cover 20. A front cover 9, a left cover 10, and a right cover 11 are vertically connected to the four sides of the base 12.

The inner sides of the left cover 10 and the right cover 11 are each provided with a beam splitter placement slot 13, and the two sides of the beam splitter 4 are embedded in the beam splitter placement slot 13.

This portion of the light mainly illuminates the base plane or specific inclined surface of the workpiece. The second light source 5 integrated at the light outlet 3 emits light directly forward as a side lighting source. Its light is scattered and homogenized by the light homogenizing plate 6 before being emitted, mainly used to highlight the side wall contour of the workpiece or to compensate for areas where the main light reflection path is insufficiently illuminated.

[0040] Near the light outlet 3, the main light reflected by the beam splitter 4 mixes and superimposes with the direct light emitted by the second light source 5 to form a uniform illumination field. The brightness of the second light source 5 is not fixed but is adaptively adjusted according to the brightness of the LED light source board 2.
