[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] The utility model provides a reflective sample measuring optical integrating sphere, such as Figures 1-4As shown, it includes a base 1, a product base 2 is installed on one side of the top of the base 1, a height adjustment component 3 is installed on the other side of the top of the base 1, a product fixture 4 is installed on the top of the product base 2, the fixture 4 clamps the lamp, an integrating sphere fixing frame 5 is installed on the height adjustment component 3, an integrating sphere body 6 is installed on the front of the integrating sphere fixing frame 5, and the integrating sphere body 6 is directly opposite the product fixture 4. The integrating sphere is cleverly designed and compact in structure. The base 1 serves as the support platform for the entire device, ensuring the stability of the test. The use of the product base 2 and the height adjustment component 3 allows the lamp under test to be flexibly installed on the product fixture 4, and its position relative to the integrating sphere body 6 can be adjusted according to the test requirements, especially the fine adjustment of the height, which greatly improves the flexibility and accuracy of the test.
[0026] The integrating sphere mounting bracket 5 securely mounts the integrating sphere body 6 on the height adjustment assembly 3, ensuring its stability and reliability during testing. The design of the integrating sphere body 6 facing the product fixture 4 allows light from the lamp to enter the sphere directly and efficiently. After being reflected and homogenized by the sphere's inner surface, it provides a stable and uniform lighting environment for testing, effectively improving test accuracy and repeatability.
[0027] In this embodiment, the height adjustment assembly 3 includes a vertical plate 31, internally mounted with a screw 32, on which a screw block 33 is mounted. The outer side of the screw block 33 is connected and fixed to the integrating sphere mounting bracket 5. Through the ingenious combination of the vertical plate 31, screw 32, and screw block 33, the height adjustment assembly 3 achieves precise adjustment of the integrating sphere body 6 relative to the product fixture 4 in the height direction. The coordination of the screw and screw block ensures smooth and precise adjustment, allowing for flexible adjustment of the integrating sphere's position during testing based on the size and testing requirements of different products, thereby improving test adaptability and accuracy.
[0028] Specifically, the top end of screw rod 32 is driven by motor 34, while the bottom end of screw rod 32 is rotatably connected to the bottom of riser 31 via a bearing. This design makes the height adjustment process more automated and convenient. The motor drive not only improves adjustment efficiency but also ensures accuracy and stability, avoiding the errors and instabilities that can occur with manual adjustment.
[0029] Furthermore, a pin hole 331 is horizontally opened in the middle of the screw slider 33. The integrating sphere fixing frame 5 includes a slider 51. The slider 51 is a rectangular frame structure that is sleeved on the outside of the vertical plate 31 and slides vertically. A pin 52 is installed inside the slider 51. The side wall of the vertical plate 31 is provided with a strip hole. The middle of the pin 52 passes through the pin hole 331, and the two ends of the pin 52 slide in conjunction with the strip hole. This achieves stable sliding and fixing of the integrating sphere fixing frame on the vertical plate 31. This design not only enhances the structural stability of the integrating sphere system, but also enables the integrating sphere body 6 to be smoothly adjusted up and down as the screw slider moves, further improving the accuracy and reliability of the test.
[0030] Furthermore, the product fixture 4 comprises a base plate 41, with side plates 42 symmetrically mounted on top. Mounted within these plates is a pressure plate 43, which is an outwardly convex arc. This design allows the fixture to securely hold lamps of varying shapes and sizes. The arc-shaped pressure plate conforms better to the product surface, improving both stability and accuracy.
[0031] Furthermore, the inner surface of the side plate 42 is provided with a groove, within which several springs 44 are mounted. One end of the spring 44 is connected to the pressure plate 43, and the other end is connected to the inner wall of the groove. This design provides the clamp with adaptive clamping force. The elastic force of the springs can adapt to the dimensional variations of different products, ensuring a secure clamping position while preventing damage to the product due to excessive clamping force.
[0032] Furthermore, a non-slip pad is installed on the bottom of the base 1. This effectively prevents the entire integrating sphere system from sliding and shaking during the test, ensuring the stability of the test. This design is of great significance for improving the accuracy and safety of the test.
[0033] Furthermore, the front light inlet of the integrating sphere body 6 is horizontally aligned with the product light emitting end on the product fixture 4. This ensures that light from the product can enter the integrating sphere directly and efficiently. This alignment design not only improves light utilization but also optimizes the accuracy and reliability of test results, providing strong support for optical performance testing, which is performed using the light-sensing device on the integrating sphere body 6.
[0034] When using the reflective sample optical integrating sphere of the present invention, first place the entire integrating sphere system on a stable workbench, ensuring that the anti-slip pad at the bottom of the base 1 is in close contact with the table surface to prevent sliding and shaking during the test. Adjust the product fixture 4 according to the size and shape of the lamp to be tested. Through the spring 44 and the arc-shaped pressure plate 43 on the inner side of the side panel 42, the lamp to be tested can be firmly clamped, while ensuring that the clamping force is moderate to avoid damage to the product. Adjust the height adjustment component 3, and drive the screw 32 to rotate through the motor 34, driving the screw slider 33 to move up and down on the vertical plate 31. The pin 52 slides in the bar hole to ensure that the integrating sphere fixing frame 5 and the integrating sphere body 6 thereon can move smoothly with the screw slider 33. Horizontally align the front light inlet of the integrating sphere body 6 with the product light emitting end on the product fixture 4 to ensure that light can directly and efficiently enter the interior of the integrating sphere.
[0035] Turn on the luminaire under test, causing it to emit light. The light is first guided by the product fixture 4 and directly illuminated by the light inlet of the integrating sphere body 6. Once inside, the light is reflected multiple times on the inner surface of the sphere and homogenized, creating a stable, uniform lighting environment. A photosensitive device (such as a photoelectric sensor or spectrometer) within the integrating sphere body 6 receives and measures the homogenized light, converting the optical signal into an electrical signal for subsequent processing and analysis. Based on test requirements, the height adjustment assembly 3 allows precise adjustment of the relative position between the integrating sphere body 6 and the luminaire under test to obtain optical performance data at different angles or distances.
[0036] After the test is complete, the data captured by the photosensitive device is processed and analyzed to determine the optical performance parameters of the lamp under test (such as light intensity distribution, color temperature, and color rendering index). Based on the test results, the optical performance of the lamp under test can be evaluated, providing strong support for product design and improvement.
[0037] Finally, it should be noted that the integrating sphere body 6 and the like in this embodiment, and the electronic components in the above-mentioned parts are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.
