Description

Technical Field

[0001] This invention relates to the field of optical measurement technology, and particularly to illuminance testing. Background Technology

[0002] A lux meter is a specialized instrument for measuring illuminance. It measures the degree to which an object is illuminated and can be used to ensure that the illuminance in places such as gymnasiums, classrooms, and factories meets standards. In complex lighting environments such as gymnasiums, classrooms, and factories, multiple light sources are usually required to achieve uniform, glare-free lighting effects. To obtain optimal lighting quality and energy efficiency, the position, angle, and even power of each light source need to be precisely arranged and adjusted.

[0003] In mixed environments containing various 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 individual areas.

[0004] Even with equipment designed to detect light intensity in a single area, it is difficult to detect the overall light intensity in a small area.

[0005] When multiple light sources are arranged in places such as gymnasiums, classrooms, and factories, existing illuminance meters, even when combined with other equipment, are difficult to accurately assist in the arrangement of light sources. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this section, the abstract and the title of the invention. Such simplifications or omissions shall not be used to limit the scope of the present invention.

[0007] The overall illuminance testing system, which integrates zoned lighting layout guidance parameters, includes a detector head, which in turn includes an ambient light detection system, and the ambient light detection system includes an illuminance testing module.

[0008] A semi-transparent, spherical, frosted inner cover is provided to cover the illuminance testing module;

[0009] The frosted inner cover has multiple hollow light cone structures fixed on the outside;

[0010] The light cone structure adopts a hollow channel with a hexagonal cross-section, and the area of ​​the hollow channel gradually decreases from the outside to the center.

[0011] The inner wall of the light cone structure is provided with a reflective layer;

[0012] The light cone structure is provided with an inlet facing outwards and an outlet facing inwards;

[0013] The light outlet faces the illuminance testing module;

[0014] Multiple hollow light cone structures are arranged around the frosted inner cover to form a spherical structure with a spherical outer surface, thus forming a light cone structure spherical cover;

[0015] The frosted inner cover is concentrically arranged with the light cone structure spherical cover;

[0016] It also includes a camera, which is covered by a frosted inner cover, and the camera's shooting area is the inner wall of the frosted inner cover;

[0017] The light cone structure enhances the light intensity received on the frosted inner cover, and the reflective layer forms optical isolation, thereby making the light spots at different light outlets appear relatively independent on the frosted inner cover.

[0018] The camera and ambient light detection system are connected to the microprocessor system;

[0019] The overall ambient light intensity is obtained by receiving uniform light rays that reflect the overall ambient light intensity after being scattered and diffused by the frosted inner cover through the illuminance test module.

[0020] The camera captures relatively independent light spots on the frosted inner cover to obtain the local light intensity of the area oriented by the corresponding light cone structure.

[0021] The overall intensity and local intensity of ambient light provide reference data for the configuration of ambient light sources.

[0022] The above design utilizes a frosted inner cover to effectively scatter, refract, and mix incident light, forming a light spot that provides a stable optical signal foundation for subsequent accurate measurements. The light cone structure, forming a spherical cover, ensures that each light source in the environment produces a corresponding light spot of varying brightness on the frosted surface. The light cone structure mixes the light from corresponding areas, facilitating detection by the sensor. This transforms the complex problem of multi-light source identification into a simple machine vision task of finding bright spots in an image. It also facilitates the identification of excessively bright or dark light sources by observing these spots, aiding in the adjustment of multiple light source arrangements in the environment. The large opening area of ​​the light cone structure's inlet allows it to capture light from a relatively wide viewing angle, effectively collecting light. The gradually decreasing cross-sectional area of ​​the hollow channel from the outside to the center creates a converging channel that focuses the light. The light exits from the smaller inner outlet, forming a more concentrated beam that is projected onto the frosted inner cover, significantly improving light energy utilization and the brightness of the light spot on the frosted inner cover surface, thus enhancing the sensitivity of the detector.

[0023] By adjusting the light intensity of local areas rather than the light intensity of a single lamp, the impact of traditional single light sources on the overall lighting layout is reduced, which is beneficial for the macro-level overall layout of multiple light sources in places such as stadiums, classrooms, and factories.

[0024] By using a hexagonal hollow channel to form a light cone structure, seamless spherical splicing can be achieved, improving mechanical strength and stability, and forming a uniformly distributed light spot effect, thereby significantly improving the accuracy of subsequent light spot positioning and the reliability of the system.

[0025] When the probe adjusts the brightness of multiple light sources, if the illuminance testing module detects that the overall ambient light intensity is too strong, the microprocessor system uses the image captured by the camera to find the brightest spot; based on the position of the spot, it determines the corresponding light cone structure, and then determines the light source corresponding to the orientation direction of the light cone structure; by reducing the intensity of the corresponding light source, the overall ambient light intensity is reduced. Conversely, if the illuminance testing module detects that the overall ambient light intensity is too weak, the microprocessor system uses the image captured by the camera to find the darkest spot; based on the position of the spot, it determines the corresponding light cone structure, and then determines the light source corresponding to the orientation direction of the light cone structure; by increasing the intensity of the corresponding light source, the overall ambient light intensity is increased.

[0026] Preferably, the device also includes a gimbal, on which the probe is mounted. The gimbal enables stable measurement by the probe after it has been positioned, reducing vibration interference.

[0027] Preferably, the gimbal is a two-axis gimbal, which has a rotation axis and a pitch axis. A gear, called a rotation gear, is connected to the rotation axis, and the rotation gear's axis of rotation coincides with the rotation axis's axis of rotation. Another gear, called a pitch adjustment gear, is connected to the pitch axis, and the pitch adjustment gear's axis of pitch coincides with the pitch axis's axis of pitch. The gimbal includes a horizontal drive motor with a horizontal drive gear meshing with the rotation gear. The gimbal also includes a pitch drive motor with a pitch drive gear meshing with the pitch adjustment gear. The two-axis gimbal enables three-dimensional spatial adjustment, suitable for adjusting the probe's position to suit different spatial light source distributions. Gear transmission allows for minimal backlash, improving the accuracy of gimbal movement and positioning.

[0028] Preferably, the horizontal drive motor and the pitch drive motor are closed-loop servo motors. This facilitates positioning after the gimbal is adjusted.

[0029] Preferably, a laser is mounted on the gimbal, the laser is housed in a frosted inner cover, and the laser emission direction of the laser is consistent with the orientation of the illuminance testing module;

[0030] The control signal output terminal of the microprocessor system controls the switch signal input terminal connected to the laser.

[0031] After the gimbal initially moves into position based on the image data from the camera, the microprocessor system controls the laser to be turned on, and the laser forms a landing point inside the frosted inner cover.

[0032] The camera then captures another image of the inner surface of the frosted inner cover, including the laser's point of impact.

[0033] The microprocessor system runs an image recognition algorithm to identify the laser's landing point as the middle position of all light spots inside the frosted inner cover;

[0034] If the laser point is not in the center of the light spot, its positional deviation is calculated, a fine-tuning command is generated and sent to the gimbal drive system, which drives the gimbal to make fine movements until the laser point falls in the center of the light spot, thus completing high-precision alignment.

[0035] The automatic positioning adjustment of the probe head aligns it with the center of the space light source, making the probe head adjustment for light illuminance measurement faster and more convenient, and improving the measurement accuracy of the probe head.

[0036] Preferably, a beam collimator is provided in the front optical path of the laser to generate a fine, sharp laser spot. This reduces the impact on the contrast test module while ensuring the laser beam is captured by the camera.

[0037] Preferably, a sealing rubber ring is provided between the frosted inner cover and the mounting edge of the gimbal. This ensures the sealing effect of the frosted inner cover and prevents dust from falling onto the camera and illumination test module, thus affecting operational accuracy.

[0038] Preferably, two cameras are provided, arranged side-by-side with the illuminance testing module, with the two cameras positioned on either side of the illuminance testing module. Images captured by at least two cameras can be compared and integrated. The centroid coordinates of the light spot from the same light source in the two images are calculated separately, and the average value is taken as the final light spot position information to improve positioning accuracy. The two images are then fused to generate a composite image with a wider field of view or higher detail, thereby improving the accuracy of light spot recognition.

[0039] Preferably, the light cone structure dome is provided with an isolation mesh of light-absorbing material, and the isolation mesh is disposed between the light outlets. This ensures that the light spots presented on the frosted inner cover are isolated from each other, avoiding overlapping and interference between light spots.

[0040] In summary, this invention offers the following advantages: Through the frosted surface and the light cone-shaped dome, each light source in the environment generates a corresponding light spot of varying brightness on the light-emitting surface of the frosted surface. This facilitates the identification of light sources in areas with excessively bright or dark spots, and aids in the adjustment of the arrangement of multiple light sources in the environment. The tapered channel of the light cone structure effectively converges light, significantly improving light energy utilization and the brightness of the light spot at the light outlet on the frosted inner dome surface, thereby enhancing the sensitivity of the detector.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0051] Example 1, Reference Figures 1-4 The overall illuminance testing system, which combines the output of zonal lighting layout guidance parameters, includes a detector head 1, which includes an ambient light detection system, and the ambient light detection system includes an illuminance testing module 2.

[0052] A semi-transparent spherical frosted inner cover 3 is provided to cover the illuminance testing module 2;

[0053] The frosted inner cover 3 has multiple hollow light cone structures 4 fixed on the outside;

[0054] The light cone structure 4 adopts a hollow channel 41 with a hexagonal cross-section, and the area of ​​the hollow channel 41 gradually decreases from the outside to the center.

[0055] The inner wall of the light cone structure 4 is provided with a reflective layer;

[0056] The light cone structure 4 is provided with an inlet facing outward and an outlet facing inward;

[0057] The light outlet faces the illuminance testing module 2;

[0058] Multiple hollow light cone structures 4 are arranged around the frosted inner cover 3 to form a spherical structure with a spherical outer surface, thus forming a light cone structure spherical cover;

[0059] The frosted inner cover 3 is concentrically arranged with the light cone structure spherical cover;

[0060] It also includes a camera 5, which is covered by a frosted inner cover 3, and the shooting area of ​​the camera 5 is the inner wall of the frosted inner cover 3;

[0061] The light cone structure 4 enhances the light intensity received on the frosted inner cover 3, and the reflective layer forms optical isolation, thereby making the light spots at different light outlets present relatively independent light spots on the frosted inner cover 3.

[0062] The camera 5 and the ambient light detection system are connected to the microprocessor system;

[0063] The illuminance test module 2 receives uniform light rays that reflect the overall intensity of ambient light after being scattered and diffusely reflected by the frosted inner cover 3, thereby obtaining the overall intensity of ambient light.

[0064] The camera 5 captures relatively independent light spots on the frosted inner cover 3 to obtain the local light intensity of the area oriented by the corresponding light cone structure 4.

[0065] The overall intensity and local intensity of ambient light provide reference data for the configuration of ambient light sources.

[0066] The above design utilizes the frosted inner cover 3 to effectively scatter, refract, and mix incident light, forming a light spot that provides a stable optical signal foundation for subsequent accurate measurements. The light cone structure 4, forming a spherical cover, ensures that each light source in the environment generates a corresponding light spot of varying brightness on the frosted surface's light-emitting surface. The light cone structure 4 mixes the light from corresponding areas, facilitating detection by the sensing element. This transforms the complex problem of multi-light source identification into a simple machine vision task of finding bright spots in an image. It also facilitates the identification of excessively bright or dark light sources by observing these spots, aiding in the adjustment of multiple light source arrangements in the environment. The large opening area of ​​the light cone structure 4 allows it to capture light from a relatively wide viewing angle, effectively collecting light. The hollow channel 41 gradually decreases in cross-sectional area from the outside to the center, forming a tapered channel that converges light. The light is emitted from the smaller inner light outlet, forming a more concentrated beam that is directed onto the frosted inner cover 3. This significantly improves the light energy utilization rate and the brightness of the light spot on the surface of the frosted inner cover 3, thereby enhancing the sensitivity of the detector head 1.

[0067] By adjusting the light intensity of local areas rather than the light intensity of a single lamp, the impact of traditional single light sources on the overall lighting layout is reduced, which is beneficial for the macro-level overall layout of multiple light sources in places such as stadiums, classrooms, and factories.

[0068] By using a hexagonal hollow channel 41 to form a light cone structure 4, seamless spherical splicing can be achieved, improving mechanical strength and stability, forming a uniformly distributed light spot effect, thereby significantly improving the accuracy of subsequent light spot positioning and the reliability of the system.

[0069] When the detector 1 adjusts the brightness of multiple light sources, and the illuminance testing module 2 detects that the overall ambient light intensity is too strong, the microprocessor system uses the image captured by the camera 5 to find the brightest spot; and based on the position of the spot, determines the light cone structure 4 corresponding to the spot, and then determines the light source corresponding to the orientation direction of the light cone structure 4; by reducing the intensity of the corresponding light source, the overall ambient light intensity is reduced. When the illuminance testing module 2 detects that the overall ambient light intensity is too weak, the microprocessor system uses the image captured by the camera 5 to find the darkest spot; and based on the position of the spot, determines the light cone structure 4 corresponding to the spot, and then determines the light source corresponding to the orientation direction of the light cone structure 4; by increasing the intensity of the corresponding light source, the overall ambient light intensity is increased.

[0070] A sealing rubber ring is provided between the frosted inner cover 3 and the mounting edge of the gimbal 6. This ensures the sealing effect of the frosted inner cover 3 and prevents dust from falling onto the camera 5 and the illumination test module 2, thus affecting the operational accuracy.

[0071] Two cameras 5 are provided, arranged side-by-side with the illumination test module 2, with the two cameras 5 positioned on either side of the illumination test module 2. Images captured by at least two cameras 5 can be compared and integrated. The centroid coordinates of the light spot from the same light source in the two images are calculated separately, and the average value is taken as the final light spot position information to improve positioning accuracy. The two images are then fused to generate a composite image with a wider field of view or higher detail, thereby improving the accuracy of light spot recognition.

[0072] The light cone structure dome is equipped with a light-absorbing material isolation mesh, which is positioned between the light outlets. This ensures that the light spots appearing on the frosted inner cover 3 are isolated from each other, preventing overlapping and interference between light spots.

[0073] In use, when measuring illuminance in a multi-light source environment, the light cone structure 4 collects light from the space through the light inlet. The light then converges through the hollow channel 41 in the light cone structure 4. The concentrated beam of light from the light source corresponding to each area of ​​the light cone structure 4 is reflected and homogenized by the reflective layer before being projected onto the frosted inner cover 3, increasing 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 illuminance testing module 2 to detect the illuminance 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. The light cone structure 4 mixes the light from the corresponding areas, facilitating detection by the detection element. Two cameras 5 capture the light spots on the frosted inner cover 3. The images captured by at least two cameras 5 can be compared and integrated. The synthesized image after fusion processing has higher detail and improves the accuracy of light spot recognition. The final image facilitates the adjustment of the brightness of the light source in each area.

[0074] Example 2, Reference Figure 1 and Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0075] It also includes a gimbal 6, on which the probe 1 is mounted. The gimbal 6 enables stable measurement by the probe 1 after it has been adjusted to the correct position, reducing vibration interference.

[0076] The gimbal 6 is a two-axis gimbal 6, which has a rotation axis and a pitch axis. A gear, called a rotation gear 61, is connected to the rotation axis, and the rotation gear 61 coincides with the axis of the rotation axis. Another gear, called a pitch adjustment gear 62, is connected to the pitch axis, and the pitch adjustment gear 62 coincides with the axis of the pitch axis. The gimbal 6 includes a horizontal drive motor with a horizontal drive gear meshing with the rotation gear 61. The gimbal 6 also includes a pitch drive motor with a pitch drive gear meshing with the pitch adjustment gear 62. The two-axis gimbal 6 enables three-dimensional spatial adjustment, suitable for adjusting the distribution of spatial light sources in the probe 1. The gear transmission allows for transmission with minimal backlash, improving the accuracy of the gimbal 6's movement and positioning.

[0077] The horizontal drive motor and the pitch drive motor are closed-loop servo motors. This facilitates positioning of the gimbal 6 after adjustment.

[0078] A laser 7 is mounted on the gimbal 6 and is housed within a frosted inner cover 3. The laser emission direction of the laser 7 is aligned with the orientation of the illuminance testing module 2. The control signal output of the microprocessor system controls the switch signal input of the laser 7. After the gimbal 6 initially moves into position based on the image data from the camera 5, the microprocessor system activates the laser 7, which forms a landing point inside the frosted inner cover 3. The camera 5 then captures another image of the inner surface of the frosted inner cover 3, including the laser landing point. The microprocessor system runs an image recognition algorithm to identify the center position of the laser landing point among all light spots inside the frosted inner cover 3. If the laser landing point is not in the center of the light spot, its positional deviation is calculated, a fine-tuning command is generated, and sent to the gimbal 6 drive system to drive the gimbal 6 to perform fine-tuning until the laser landing point falls in the center of the light spot, completing high-precision alignment.

[0079] The detector 1 can be automatically positioned to align with the center of the space light source, making it faster and more convenient to adjust the position of the detector 1 to measure the illuminance.

[0080] A beam collimator is provided in the front optical path of the laser 7 to generate a fine, sharp laser spot. This reduces the impact of the contrast test module 2 on the laser beam from the laser 7, making the laser beam from the laser 7 a small spot that can be captured by the camera.

[0081] In use, when the probe 1 is probing, the camera 5 captures an image of the inner surface of the light-transmitting spherical cover and transmits the image data to the microprocessor system. The microprocessor system performs image processing, identifies the position of the bright light source in the image, and converts the position information of the light cone structure 4 at the center of the light spot into control commands for driving the gimbal 6, thereby driving the probe 1 toward the target light source. The laser 7 is activated, leaving a laser point on the spherical cover. The camera 5 captures an image again to verify whether the point falls within the central light spot. The verification image information is sent to the microprocessor system to verify whether the probe 1 is pointing toward the light source. If there is a deviation, fine-tuning is performed until the probe 1 is pointing toward the central light spot, thereby improving the measurement accuracy of the probe 1.

[0082] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
