[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Please see Figure 1-9 This utility model provides a technical solution: a light source module for visual inspection, including a housing 10. Inside the housing 10, from left to right, there are a diffuser plate 60, a base plate 50 and a PCB board 30. The base plate 50 is provided with an LED light strip 52 that can illuminate from multiple angles. The LED light strip 52 is electrically connected to the PCB board 30. The PCB board 30 controls the operation of the LED light strip 52 on the base plate 50.
[0028] The LED light strip 52 is equipped with LED beads that can emit light. The LED beads can form light in different directions by illuminating different directions.
[0029] The housing 10 has a light outlet on the front. The LED light strip 52 generates light at different angles, which is diffused by the diffuser plate 60 and then emitted from the light outlet. The diffuser plate 60, the base plate 50 and the PCB board 30 are assembled inside the housing 10. The PCB board 30 controls the operation of the LED light strip 52 on the base plate 50 at different illumination angles. Different LED light strips 52 can emit light at different angles, which are then diffused by the diffuser plate 60 and emitted from the light outlet, thus forming multi-angle illumination light, which can cope with the visual inspection of various complex surfaces.
[0030] The base plate 50 has a hollowed-out groove at the center of its surface. Support screws 51, which increase in height from the inside to the outside, are arranged around the hollowed-out groove on the surface of the base plate 50. The ends of the support screws 51 are provided with inwardly inclined support plates. LED light strips 52 are set on the support plates. LED light strips 52 on different support plates can form light at different angles. The support plates are supported by support screws 51 of different heights, so as to ensure that different LED light strips 52 are located on different planes. Then, the support plates are bent at different angles to fix LED light strips 52 at different angles, thereby forming LED light strips 52 illuminating light at various angles.
[0031] The hollowed-out groove is equipped with a middle frame light shield 40, which prevents the light emitted by the LED light strip 52 from leaking out of the hollowed-out groove.
[0032] The PCB board 30 has a first slot at the center of its surface that matches the light shield 40 of the middle frame, and the light shield 40 of the middle frame can pass through the PCB board 30 through the first slot.
[0033] The back of the housing 10 is provided with a cover plate 20, which seals the diffuser plate 60, the base plate 50 and the PCB board 30 inside the housing 10, thereby assembling the light source module.
[0034] The cover plate 20 has a second slot on its surface that matches the light shield 40 of the middle frame, and the diffuser plate 60 has a third slot on its surface that matches the light shield 40 of the middle frame. The light shield 40 of the middle frame passes through the third slot, the hollow slot, the first slot and the second slot from left to right. Specifically, during assembly, LED light strips 52 at different angles are first installed on the base plate 50. Then, from left to right, the diffuser plate 60, the base plate 50 and the PCB board 30 are assembled into the housing 10. Then, the cover plate 20 is assembled on the back of the housing 10. The cover plate 20 seals the diffuser plate 60, the base plate 50 and the PCB board 30 into the housing 10. Next, the light shield 40 of the middle frame passes through the third slot, the hollow slot, the first slot and the second slot from left to right and is fixed in place. The light shield 40 of the middle frame blocks the axis of the light source module to prevent light leakage.
[0035] The cover plate 20 is inlaid with two rows of aviation plugs 21, with three aviation plugs 21 in each row, for a total of six aviation plugs 21. The aviation plugs 21 are electrically connected to the PCB board 30, and the PCB board 30 is connected to an external power supply and control switch through the aviation plugs 21, thereby controlling the operation of the light source module.
[0036] Among them, the aviation plug 21 adopts the WS28-24 aircraft carrier head.
[0037] The diffuser plate 60 is made of milky white diffuser plate, which makes the light diffuse more evenly.
[0038] Working principle: In use, first install LED light strips 52 at different angles on the base plate 50. Then, from left to right, assemble the diffuser plate 60, the base plate 50, and the PCB board 30 into the housing 10. Next, assemble the cover plate 20 on the back of the housing 10, sealing the diffuser plate 60, the base plate 50, and the PCB board 30 inside the housing 10. Then, insert the middle frame light shield 40 through the third slot, the hollow slot, the first slot, and the second slot from left to right, and fix the middle frame light shield 40, thus assembling the light source module. Then, the PCB board 30 controls the LED light strips 52 at different illumination angles on the base plate 50 to work. Different LED light strips 52 can emit light at different angles, which are then diffused by the diffuser plate 60 and emitted from the light outlet, thus forming multi-angle illumination light, which can cope with the visual inspection of various complex surfaces.
[0039] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
