Description
Technical Field
[0001] The present invention relates to the technical field of optical measurement, in particular to illumination testing. Background Art
[0002] A lux meter is a specialized instrument for measuring illumination. It measures the degree to which an object is illuminated. This measurement ensures that illumination levels in places like gymnasiums, classrooms, and factories meet standards. Complex lighting environments like these often require multiple light sources to achieve uniform, glare-free illumination. To achieve optimal lighting quality and energy efficiency, the position, angle, and even power of each light source must be meticulously arranged and adjusted.
[0003] In a mixed environment containing multiple light sources such as natural light, general lighting, and accent lighting, traditional illuminance meters can only measure the total illuminance value and cannot distinguish the contribution of light intensity in a single area.
[0004] Even with detection equipment for the light intensity of a single area, it is difficult to detect the comprehensive light in a small area.
[0005] When arranging multiple light sources in places such as gymnasiums, classrooms, and factories, existing illuminance meters, even when used in conjunction with other equipment, are unable to accurately assist in the arrangement of light sources. Summary of the Invention
[0006] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the title of the invention of this application to avoid blurring the purpose of this section, the abstract of the specification and the title of the invention, and such simplifications or omissions cannot be used to limit the scope of the invention.
[0007] The illumination test system that integrates the output of the zoned lighting arrangement guidance parameters includes a detection head, the detection head includes an ambient light detection system, and the ambient light detection system includes an illumination test module. A translucent spherical frosted inner cover is provided, and the frosted inner cover covers the illumination test module; A plurality of hollow light cone structures are fixedly arranged outside the frosted inner cover; The light cone structure adopts a hollow channel with a hexagonal cross section, and the cross-sectional area of the hollow channel gradually decreases from the outside to the center; The inner wall of the light cone structure is provided with a reflective layer; The light cone structure is provided with a light inlet facing outward and a light outlet facing inward; The light outlet faces the illumination test module; A plurality of hollow light cone structures are arranged around the frosted inner cover to form a spherical structure with a spherical outer surface, forming a light cone structure spherical cover; The frosted inner cover is arranged concentrically with the light cone structure ball cover; Further comprising a camera, the frosted inner cover covers the camera, and a shooting area of the camera is an inner wall of the frosted inner cover; The light cone structure enhances the received light intensity on the frosted inner cover, and forms optical isolation through the reflective layer, so that different light outlets present relatively independent light spots on the frosted inner cover; The camera and the ambient light detection system are connected to a microprocessor system; The uniform light rays formed after scattering and diffuse reflection of the ambient light through the frosted inner cover are received by the illumination test module to obtain the overall intensity of the ambient light; The camera shoots the relatively independent light spots presented on the frosted inner cover to obtain the local light intensity of the area corresponding to the light cone structure; The overall intensity of the ambient light and the local light intensity provide reference data for the configuration of the ambient light source.
[0008] The above design: the frosted inner cover can fully scatter, refract and mix the incident light to form a light spot, which provides a stable light signal basis for subsequent accurate measurement. The light cone structure ball cover formed by the light cone structure will produce a corresponding light spot with different brightness on the light-emitting surface of the frosted surface for each light source in the environment. The light cone structure mixes the light of the corresponding area to facilitate the detection of the detection element, which converts the complex multi-light source recognition problem into a simple machine vision of finding bright spots on the image. It is convenient to confirm the area of the over-bright or over-dark light source through the over-bright or over-dark bright spot, and it is convenient to assist the arrangement and adjustment of multiple light sources in the environment. The large opening area of the light inlet of the light cone structure allows it to capture light from a relatively wide angle range, which can effectively collect light. The hollow channel gradually reduces the area of the cross section from the outside to the center to form a tapered channel to converge light. The light is emitted from the small light outlet on the inside to form a more concentrated light beam, which is projected to the frosted inner cover, significantly improving the light energy utilization rate and the brightness of the light spot on the surface of the frosted inner cover, and improving the sensitivity of the probe head.
[0009] By adjusting the local area light intensity instead of the light intensity of a certain lamp, the influence of traditional single light source on the overall light layout is reduced, which is beneficial to the macroscopic overall layout of multiple light sources in places such as gymnasiums, classrooms and workshops.
[0010] By adopting the hexagonal hollow channel to form the light cone structure, seamless spherical splicing can be achieved, the mechanical strength and stability are improved, and a uniformly distributed light spot effect is formed, thereby significantly improving the accuracy of subsequent light spot positioning and the reliability of the system.
[0011] When the probe head adjusts the brightness of multiple light sources as a whole, when the illuminance test module detects that the overall intensity of the ambient light is too strong, the microprocessor system finds the brightest light spot through the image captured by the camera, and determines the light cone structure corresponding to the light spot according to the position of the light spot, and then determines the light source corresponding to the direction of the orientation of the light cone structure; the overall intensity of the ambient light is reduced by reducing the intensity of the corresponding light source. When the illuminance test module detects that the overall intensity of the ambient light is too weak, the microprocessor system finds the darkest light spot through the image captured by the camera, and determines the light cone structure corresponding to the light spot according to the position of the light spot, and then determines the light source corresponding to the direction of the orientation of the light cone structure; the overall intensity of the ambient light is increased by increasing the intensity of the corresponding light source.

The rotation axis is connected with a gear, referred to as a rotation gear, and the rotation gear is coaxial with the rotation axis.

The holder includes a horizontal drive motor, and the horizontal drive motor is provided with a horizontal drive gear engaged with the rotation gear. The holder further includes a pitch drive motor, and the pitch drive motor is provided with a pitch drive gear engaged with the pitch adjustment gear. The two-axis holder can be used to adjust the three-dimensional space, and is suitable for adjusting the spatial light source distribution of the probe head. The gear transmission can realize smaller backlash transmission, thereby improving the accuracy of the movement of the holder and the accuracy of the position positioning.
[0014] Preferably, the horizontal drive motor and the pitch drive motor are closed-loop servo motors. The closed-loop servo motors can be used to facilitate the positioning of the holder after the holder is adjusted to a position.
[0015] Preferably, a laser is arranged on the holder, and the laser is arranged in a frosted inner cover. The laser emission direction of the laser is consistent with the orientation of the illuminance test module. A control signal output end of the microprocessor system is connected with a switch signal input end of the laser. After the holder is preliminarily moved to a position according to the image data of the camera, the microprocessor system controls the laser to be turned on, and the laser forms a landing point on the inner side of the frosted inner cover. The camera captures an image of the inner surface of the frosted inner cover again, and the image includes the landing point of the laser. The microprocessor system runs an image recognition algorithm to identify that the landing point of the laser is in the middle position of all light spots in the frosted inner cover. If the laser landing point is not in the center of the light spot, the position deviation is calculated, the fine adjustment instruction is generated and sent to the holder driving system, the holder is driven to fine adjustment until the laser landing point falls in the center of the light spot, and the high-precision alignment is completed.
[0016] The automatic position adjustment of the detection head to the middle position of the space light source is realized, the detection head is adjusted to measure light illumination more quickly and conveniently, and the measurement accuracy of the detection head is improved.

[0019] Preferably, two cameras are arranged, and the two cameras are arranged side by side with the illumination test module and are arranged on both sides of the illumination test module. The pictures photographed by the at least two cameras can be compared and integrated, the centroid coordinates of the same light spot in the two images are calculated respectively, and the average value is taken as the final light spot position information, so as to improve the positioning accuracy; the two images are fused to generate a composite image with a wider field of view or higher details, and the accuracy of light spot recognition is improved.
[0020] Preferably, the light cone structure ball cover is provided with a light-absorbing material isolation grid arranged between the light outlets. The light spots presented on the frosted inner cover are isolated from each other, and the situation of light spot overlapping and interfering with each other is avoided.
[0021] In summary, the present application has the following beneficial effects: through the frosted surface and the light cone structure ball cover, the light source in each area of the environment will generate a corresponding light spot with different brightness on the light-emitting surface of the frosted surface.

[0027] Thirdly, the "one embodiment" or "embodiment" referred to herein can include specific features, structures or characteristics contained in less than one implementation of the present application. "In one embodiment" appearing in different places in the specification does not refer to the same embodiment, nor is it an embodiment that is separate or selectively excluded from other embodiments.
[0028] Embodiment 1, refer to Figures 1-4 The illumination test system of the whole combined sub-area light arrangement guiding parameter output, comprising a probe head 1, the probe head 1 comprising an ambient light detection system, the ambient light detection system comprising an illumination test module 2.
[0029] A translucent spherical diffuser inner cover 3 is arranged to cover the illuminance test module 2; A plurality of hollow light cone structures 4 are arranged on the outer surface of the diffuser inner cover 3; The light cone structure 4 is a hollow channel 41 with a hexagonal cross section, and the cross-sectional area of the hollow channel 41 gradually decreases from the outer side to the center; The inner wall of the light cone structure 4 is provided with a reflective layer; The light cone structure 4 is provided with an entrance on the outer side and an exit on the inner side; The exit is directed towards the illuminance test module 2; A plurality of hollow light cone structures 4 are arranged in a spherical structure on the outer side of the diffuser inner cover 3, forming a light cone structure spherical cover; The diffuser inner cover 3 is concentrically arranged with the light cone structure spherical cover; It also includes a camera 5, and the diffuser inner cover 3 covers the camera 5, and the shooting area of the camera 5 is the inner wall of the diffuser inner cover 3; Through the light cone structure 4, the received light intensity on the diffuser inner cover 3 is enhanced, and the optical isolation is formed through the reflective layer, so that the different light exits on the diffuser inner cover 3 present relatively independent light spots; The camera 5 and the ambient light detection system are connected to a microprocessor system; The illuminance test module 2 receives uniform light that reflects the overall intensity of the ambient light after scattering and diffuse reflection by the diffuser inner cover 3, and obtains the overall intensity of the ambient light; The camera 5 shoots the relatively independent light spots on the diffuser inner cover 3, and obtains the local light intensity of the area corresponding to the light cone structure 4; The overall intensity of the ambient light and the local light intensity provide reference data for the configuration of the ambient light source.
[0030] The above design: through the sanding inner cover 3, the incident light can be fully scattered, refracted and mixed, and the formed light spot provides a stable light signal basis for subsequent accurate measurement. The light cone structure 4 forms a light cone structure dome. The light source in each area of the environment will produce a corresponding light spot with different brightness on the light-emitting surface of the sanding surface. The light cone structure 4 mixes the light of the corresponding area of the light source to facilitate the detection of the detection element, which converts the complex multi-light source recognition problem into a simple machine vision of finding bright spots on the image. It is convenient to confirm the area of the over-bright or over-dark light source through the over-bright or over-dark bright spot, and it is convenient to assist the arrangement adjustment of multiple light sources in the environment. The large opening area of the light inlet of the light cone structure 4 allows it to capture light from a relatively wide viewing angle range, which can effectively collect light. The hollow channel 41 gradually reduces the cross-sectional area from the outside to the center, forming a tapered channel to converge light. The light is emitted from the small light outlet on the inside, forming a more concentrated light beam, which is projected onto the sanding inner cover 3, significantly improving the light energy utilization rate and the brightness of the light spot on the surface of the sanding inner cover 3, and improving the sensitivity of the probe head 1.
[0031] By adjusting the light intensity of the local area instead of the light intensity of a certain lamp, the influence of traditional single light source on the overall light layout is reduced, which is beneficial to the macroscopic overall layout of multiple light sources in places such as gymnasiums, classrooms and workshops.
[0032] By adopting the hexagonal hollow channel 41 to form the light cone structure 4, seamless spherical splicing can be achieved, the mechanical strength and stability are improved, and a uniformly distributed light spot effect is formed, thereby significantly improving the accuracy of subsequent light spot positioning and the reliability of the system.
[0033] When the probe head 1 adjusts the brightness of multiple light sources, the illuminance test module 2 detects that the overall intensity of the environment light is too strong, the microprocessor system finds the brightest light spot through the image captured by the camera 5, and determines the light cone structure 4 corresponding to the light spot according to the position of the light spot, and then determines the light source corresponding to the direction of the light cone structure 4. By reducing the intensity of the corresponding light source, the overall intensity of the environment light is reduced. When the illuminance test module 2 detects that the overall intensity of the environment light is too weak, the microprocessor system finds the darkest light spot through the image captured by the camera 5, and determines the light cone structure 4 corresponding to the light spot according to the position of the light spot, and then determines the light source corresponding to the direction of the light cone structure 4. By increasing the intensity of the corresponding light source, the overall intensity of the environment light is increased.
[0034] A sealed rubber ring is arranged between the mounting edge of the sanding inner cover 3 and the gimbal 6. The sealing effect of the sanding inner cover 3 is guaranteed, and dust falling on the camera 5 and the illuminance test module 2 is prevented to affect the operation accuracy.
[0035] The camera 5 is provided with two, two cameras 5 are arranged side by side with the illumination test module 2, and the two cameras 5 are arranged on both sides of the illumination test module 2. The pictures taken by the at least two cameras 5 can be compared and integrated, the centroid coordinates of the same light spot in the two images are calculated respectively, and the average value is taken as the final light spot position information, which is used to improve the positioning accuracy; the two images are fused to generate a synthetic image with wider field of view or higher detail, improving the accuracy of light spot identification.
[0036] The light cone structure ball cover is provided with an isolation grid of light-absorbing material, which is arranged between the light outlets. The light spots presented on the frosted inner cover 3 are isolated from each other, avoiding the overlapping of light spots and mutual interference.
[0037] In use, when measuring the illumination in a multi-light source environment, the light cone structure 4 collects light in the space through the light inlet, the light is converged through the hollow channel 41 of the light cone structure 4, and the concentrated light beam is projected to the frosted inner cover 3 after being reflected by the light reflection layer, improving the brightness of the light spot on the surface of the frosted inner cover 3. The frosted inner cover 3 can fully scatter, refract and mix the incident light, facilitating the illumination test module 2 to detect the illumination of the environment. Each light source in the environment will produce a corresponding light spot with different brightness on the light-emitting surface of the frosted surface, and the light cone structure 4 mixes the light of the corresponding area, facilitating the detection of the detection element. The two cameras 5 shoot the light spots on the frosted inner cover 3, and the pictures taken by the at least two cameras 5 can be compared and integrated, and the picture after fusion processing has higher details, improving the accuracy of light spot identification. The finally formed image facilitates the adjustment of the brightness of the area light source.

[0041] The horizontal drive motor and the pitch drive motor are closed-loop servo motors, which facilitate the positioning of the holder 6 after the adjustment of the position.
[0042] The holder 6 is provided with a laser 7, which is arranged in the frosted inner cover 3, and the laser emission direction of the laser 7 is consistent with the direction of the illumination test module 2; the control signal output end of the microprocessor system is connected with the switch signal input end of the laser 7; after the holder 6 is preliminarily moved to the position according to the image data of the camera 5, the microprocessor system controls the laser 7 to be turned on, and the laser 7 forms a falling point inside the frosted inner cover 3; the camera 5 takes an image of the inner surface of the frosted inner cover 3 again, which contains the laser falling point; the microprocessor system runs an image recognition algorithm to identify the middle position of the laser falling point among all the light spots in the frosted inner cover 3; if the laser falling point is not in the central light spot, the position deviation is calculated, a fine adjustment instruction is generated and sent to the holder 6 drive system, and the holder 6 is driven to move finely until the laser falling point falls in the central light spot, and the high-precision alignment is completed.
[0043] The automatic position adjustment of the detection head 1 realizes the alignment of the middle position of the spatial light source, and the detection head 1 is adjusted to measure the light illumination more quickly and conveniently.
[0044] A beam collimator is arranged in the front light path of the laser 7, which is used to generate a fine laser spot. The laser beam of the laser 7 is condensed into a small light spot, which can be photographed by the camera while reducing the influence on the illumination test module 2.
[0045] In use, when the probe head 1 is detecting, the camera 5 takes an image of the inner surface of the light-transmitting dome and transmits the image data to the microprocessor system, which runs image processing to identify the position of the bright light source in the image. The microprocessor system converts the position information of the light spot center light cone structure 4 into control instructions for driving the gimbal 6, thereby driving the probe head 1 to point towards the target light source. The laser 7 is turned on to leave a laser landing point on the dome. The camera 5 takes another image to verify whether the landing point is in the center light spot. The verification image information is sent to the microprocessor system to verify whether the probe head 1 is pointing towards the light source. If there is a deviation, fine adjustment is performed until the probe head 1 is pointing towards the center light spot, thereby improving the measurement accuracy of the probe head 1.
