Description
Technical Field
[0001] The present invention relates to the technical field of light intensity detection of lamps, and specifically relates to a continuous light intensity detection device for LED indoor lamps. Background Art
[0002] A continuous light intensity detection device for LED indoor lamps is a device specifically used to measure and evaluate the luminous intensity of LED indoor lamps in a continuous working state. With the wide application of LED lighting technology, the requirements for the quality and performance of LED lamps are also increasing day by day. The continuous light intensity detection device plays an important role in ensuring the quality and performance of LED lamps;
[0003] In the Chinese invention with the application publication number CN119124572A, a clamping device for lamp testing is disclosed, which includes a base, a rotating seat, and a clamping frame. The rotating seat is rotatably arranged on the base around a first rotating shaft, and the clamping frame is rotatably arranged on the rotating seat around a second rotating shaft. The first rotating shaft and the second rotating shaft are skew intersecting. A plurality of clamping members for clamping the lamp are slidably arranged on the clamping frame, and the clamping members are connected to the clamping frame through elastic members. The elastic members are used to drive the plurality of clamping members to slide towards the center of the clamping frame. The clamping device for lamp testing of the present invention enables the lamp clamped on the clamping frame to change multiple different angles through the rotational cooperation of the rotating seat and the clamping frame, and can perform light intensity detection in multiple different directions, and the detection of the light intensity of the lamp is very comprehensive;
[0004] However, the device in the cited document still has the following defects in specific use:
[0005] 1. Compared with the device in the cited document, through the rotational cooperation of the rotating seat and the clamping frame, the lamp clamped on the clamping frame can change multiple different angles, and light intensity detection in multiple different directions can be performed. At the same time, the plurality of clamping members on the clamping members can switch clamping surfaces of different shapes to adapt to clamping lamps with different side shapes, and the clamping range of the plurality of clamping members can be adjusted;
[0006] In the actual use process, when using a symmetrical fixture to clamp the lamp, the lamp can only be limited in a single dimension, and the restraint in other directions is relatively weak. Therefore, when the lamp rotates, in addition to the limited dimension, forces in other directions, such as gravity and inertial force, will affect the lamp. Also, since the shapes of most LED indoor lamps are not completely regular and symmetrical, the center of gravity of the lamp is not necessarily at the geometric center. When the lamp is clamped and rotated, due to the fixture only providing single-dimensional limitation, the center of gravity of the lamp will deviate from the support point as the rotation angle changes, resulting in an unstable center of gravity of the lamp during rotation;
[0007] The unstable center of gravity causes the lamp to shake or tilt during rotation, resulting in uncontrollable changes in the light-emitting angle and direction of the lamp. This directly affects the light intensity signal received by the light intensity detector, leading to large errors in the measurement results and unable to accurately reflect the true light intensity distribution of the lamp at various angles;
[0008] 2. Moreover, while this symmetric structure ensures the clamping stability of the lamp, it also brings the problem of light blockage. When the light intensity detector receives the light emitted by the lamp from a certain angle, the corresponding side of the fixture will be directly in the propagation path of the light, thus blocking the light;
[0009] Due to the light blockage by the fixture, the detector cannot receive the complete light intensity signal of the lamp at certain angles, which will lead to the missing of light intensity distribution measurement data and unable to accurately draw the complete light intensity distribution curve of the lamp. For example, when measuring the side light intensity of the lamp, if the fixture blocks part of the light, then the light intensity value received by the detector will be less than the actual value, making the measurement result unable to truly reflect the light intensity of the lamp at this angle;
[0010] 3. Finally, for the device in the cited document, by switching the clamping surfaces of different shapes, it can adapt to clamping lamps with different side shapes, and the clamping ranges of multiple clamping parts can be adjusted to facilitate clamping lamps of different sizes and specifications. In actual operation, to adapt to lamps of different shapes and switch the clamping surface, a series of operation steps are required. Moreover, after each switching of the clamping surface, it is necessary to re-calibrate the clamping position and angle to ensure the accurate and stable position of the lamp during the detection process. Repeatedly switching the clamping surface will cause wear and looseness of the clamping parts, thus affecting the clamping stability. When the clamping is unstable, the lamp will move or shake slightly during the detection process, thereby affecting the accuracy of the detection result;
[0011] Therefore, in view of this, the present invention proposes a continuous light intensity detection device for LED indoor lamps to make up for and improve the deficiencies of the prior art. Summary of the Invention
[0012] To solve the above technical problems, the present invention provides a continuous light intensity detection device for LED indoor lamps to solve the technical problems raised in the above background technology.
[0013] To achieve the above object, the technical solution adopted by the present invention is: a continuous light intensity detection device for LED indoor lamps, used for detecting the light intensity of a lamp body, including a main body bracket, a driving module is installed above the main body bracket, and a multi-dimensional limiting mechanism is arranged above the main body bracket, and the multi-dimensional limiting mechanism is used to ensure the stability of the lamp body during detection.
[0014] Further, the multi-dimensional limiting mechanism includes an adjustment disk installed outside the driving module. The surface of the adjustment disk is evenly penetrated with curved grooves. A connecting rod group is installed inside the curved grooves. A limiting frame is installed outside the connecting rod group. A driving disk is fixedly connected to the side wall of the limiting frame. One end of the connecting rod group away from the adjustment disk is fixedly connected to a fixed shell. A clamping member is installed on the side wall of the fixed shell. A mounting seat is rotatably connected to the surface of the adjustment disk. The mounting seat is located at the exact center position on the surface of the adjustment disk. The adjustment disk and the lamp body are threadedly connected through the mounting seat.
[0015] Further, the adjustment disk and the connecting rod group are slidably connected through the curved grooves, and the connecting rod group is initially located at one end away from the adjustment disk.
[0016] Further, rectangular grooves are provided at the positions corresponding to the connecting rod group on the surface of the limiting frame. The connecting rod group and the limiting frame are slidably connected through the rectangular grooves.
[0017] Further, the clamping member is integrally composed of an elastic curved rod and a rubber pad. The two ends of the elastic curved rod are respectively fixedly connected to the fixed shell and the rubber pad.
[0018] Further, the connecting rod group is integrally composed of no less than three connecting rods. The three connecting rods are evenly distributed around the center of the adjustment disk. The lengths of the connecting rods in the connecting rod group are different, and the connecting rods respectively correspond to different parts on the outside of the lamp body.
[0019] Further, a centering detection mechanism is provided outside the driving module. The centering detection mechanism is used to centrally collect and detect the light emitted by the lamp body. The centering detection mechanism includes a main control shaft installed above the driving module. A detector is installed at one end of the main control shaft away from the driving module. A converging frame is installed inside the detector. Shading groups are fixedly connected to both side walls of the main control shaft.
[0020] Further, the converging frame is integrally composed of no less than four rectangular plates. Every two of the four rectangular plates form a group. The rectangular plates in each group are installed obliquely in a form with a narrower upper part and a wider lower part. The central positions of the detector, the lamp body, and the adapter pad are all located in the same vertical plane.
[0021] Further, a transmission member is installed on the outer wall of the driving module. A support shaft is installed inside the transmission member. One end of the support shaft away from the transmission member is fixedly connected to a threaded shaft. A threaded sleeve ring is threadedly connected to the outer wall of the threaded shaft. A driving ring is fixedly connected to the outer wall of the threaded sleeve ring. Elastic plates are symmetrically installed on the outer wall of the driving ring.

[0022] Further, the transmission member as a whole is composed of an upper and a lower pulley and a belt. A ball screw structure is formed between the threaded shaft and the threaded collar. Bending grooves are provided on the outer wall of the drive ring corresponding to the positions of the elastic plates.

[0023] Further, the drive module includes a drive motor and a circuit controller. The adjustment disc is rotatably connected to the outer wall of the output shaft end of the drive motor in the drive module. The drive disc is fixedly connected to the outer wall of the output shaft end of the drive motor in the drive module. The pulleys in the transmission member are respectively fixedly connected to the output shaft end of the drive motor in the drive module and the support shaft.
[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0025] By introducing the connecting rod group, the device adopts an asymmetric multi-dimensional clamping method. Through the connection and layout of the connecting rod group, stable binding forces can be applied to the lamp from multiple directions, thereby providing supporting forces in the axial direction and other inclined directions of the lamp. When the lamp is affected by gravity, the multi-dimensional clamping assembly can disperse the gravity from multiple angles to prevent the lamp from sinking or tilting due to gravity. When inertial forces are generated during the rotation of the lamp, the clamping assembly can resist the inertial forces from different directions to ensure that the lamp always remains in the set position during rotation without shaking or displacement.
[0026] Compared with the prior art which can only provide limit in a single dimension and has weak constraints in other directions, the multi-dimensional clamping assembly can firmly clamp and limit the lamp in multiple directions. Through this design, the influence of external forces such as gravity and inertial forces received by the lamp during rotation is effectively resisted, ensuring that the center of gravity of the lamp remains stable at any rotation angle and avoiding the occurrence of shaking or tilting phenomena.
[0027] Particularly importantly, during the light intensity detection process, when the detector receives the light emitted by the lamp, the asymmetric clamping design can ensure that the fixture is not directly in the light propagation path, enabling the detector to receive complete light intensity signals of the lamp at various angles, thereby accurately drawing a complete light intensity distribution curve of the lamp, truly reflecting the light intensity conditions of the lamp at different angles, and effectively improving the accuracy and reliability of the light intensity detection.
[0028] Among them, when the clamping member is attached to the outside of the lamp, it can provide a certain elastic support. During the process of clamping the lamp, this elastic support can better enable the rubber pad in the clamping member to change its own shape, thereby adapting to lamps of different shapes and sizes, making the clamping more stable and firm. At the same time, the elastic support can also buffer the impact force received by the lamp during rotation, avoiding damage to the lamp due to excessive force, and further improving the safety and stability of the lamp during the detection process;
[0029] Among them, this device adopts a clamping method similar to three-point clamping. From the perspective of high triangle stability, this clamping method has higher stability. During the rotation of the lamp, three-point clamping can effectively limit the movement and shaking of the lamp in multiple directions, ensuring that the light-emitting angle and direction of the lamp remain stable, so that the light intensity signal received by the light intensity detector is more accurate and stable. At the same time, three-point clamping can also better adapt to the center-of-gravity changes of lamps of different shapes and sizes, improving the versatility and adaptability of the device;
[0030] By ensuring that the position of the detector remains unchanged and only changing the detection position of the lamp, this device can precisely control the distance between the light source and the detector. No matter how the lamp changes its angle or position, the detector always remains in a fixed position, thus ensuring that the distance from the light source to the detector during each measurement remains the same, and further making the measurement results more accurate and reliable, and being able to truly reflect the light intensity distribution of the lamp at various angles;
[0031] Particularly importantly, a converging frame composed of no less than four rectangular plates is arranged at the output end of the detector, and the rectangular plates are installed obliquely in a form with a narrower upper part and a wider lower part, which can effectively converge the light emitted locally by the lamp. When the lamp emits light, the light will diverge in all directions during propagation, resulting in a weakening of the light signal intensity received by the detector. However, the special structure of the converging frame can change the propagation direction of the light, converge the originally divergent light onto the detector, increase the light signal intensity received by the detector, and further enable the detector to receive a stronger light signal, thereby improving the sensitivity and accuracy of the detection;
[0032] Among them, the light-shielding group is also installed obliquely on both sides of the detector, which can, to a certain extent, block the interference of external stray light. In the actual detection environment, there will be various light sources and reflectors around, which will all generate stray light and affect the accurate measurement of the light intensity of the lamp by the detector. However, the light-shielding group structure can form a relatively enclosed space for receiving light, reducing the possibility of external stray light entering the detector, so that the detector mainly receives the light emitted by the lamp, further improving the accuracy and stability of the detection result;
[0033] By setting the other side of the light illumination as the shadow surface and adopting a light-absorbing and anti-reflection design on both sides of the adapter pad, this device can effectively absorb stray light from all directions. When the lamp body emits light, some light will irradiate onto other components inside the device and be reflected. Without light-absorbing materials, some of these reflected lights will enter the detector, resulting in the light signal received by the detector containing components of stray light, making the measurement result on the high side and inaccurate. However, the light-absorbing materials can absorb these stray lights, ensuring that the detector mainly receives the light directly emitted by the lamp body, thereby improving the accuracy of light intensity detection;
[0034] Moreover, the introduction of the adapter pad helps to create a stable and uniform detection environment. By absorbing the excess light, it provides a reliable detection atmosphere for the detector, ensuring the consistency and reliability of each detection result, which is beneficial to improving the detection accuracy and repeatability;
[0035] Particularly importantly, during the process of the lamp switching angles, the adapter pad can perform intermittent flipping movements through the driving ring below, and then cooperate with the switching of the position and angle of the lamp. Through this design of synchronously flipping movements to adjust the position, the light-absorbing material on the adapter pad can always be in the best light-absorbing position. According to different angles of the lamp, it can absorb the stray light that may be generated in real time. When the lamp body rotates to a certain specific angle, the adapter pad will correspondingly flip to the appropriate position to ensure that its light-absorbing material can effectively absorb the scattered light and reflected light generated by the lamp at this angle, further reducing the interference of stray light on light intensity detection;
[0036] Furthermore, different types of lamps or different detection requirements need the lamp to perform light intensity detection at different angles, and the adapter pad can perform synchronous flipping movements along with the change of the position and angle of the lamp, enabling the device to adapt to various complex detection scenarios and lamp types. No matter how the angle of the lamp changes, the adapter pad can timely adjust its position to ensure the consistency and effectiveness of the light-absorbing effect, improving the versatility and flexibility of the device;
[0037] In addition, the linkage design between the adapter pad and the lamp body makes the entire device more coordinated and stable during operation. When the lamp body rotates to switch angles, the adapter pad performs synchronous flipping movements through the coordinated action of components such as the driving ring, threaded shaft, and threaded collar. The movements of each component cooperate with each other, avoiding problems such as device instability or structural looseness caused by the movement of a single component. Through this way of coordinated movement, it helps to maintain the overall structural stability of the device, extend the service life of the device, and reduce detection errors caused by mechanical failures.

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0054] Please refer to Figures 1 to 2As shown in the figure, a continuous light intensity detection device for an LED indoor lamp is used to detect the light intensity of the lamp body 12. It includes a main body bracket 1. Above the main body bracket 1, a driving module 11 is installed. Above the main body bracket 1, a multi-dimensional limiting mechanism 2 is provided. The multi-dimensional limiting mechanism 2 is used to ensure the stability of the lamp body 12 during detection. It should be noted that the driving module 11 includes a driving motor and a circuit controller. The adjusting disk 21 is rotatably connected to the outer wall of the output shaft end of the driving motor in the driving module 11, and the driving disk 25 is fixedly connected to the outer wall of the output shaft end of the driving motor in the driving module 11.
[0055] Please refer to Figures 2 to 6 As shown in the figure, the multi-dimensional limiting mechanism 2 includes an adjusting disk 21 installed outside the driving module 11. The surface of the adjusting disk 21 is evenly penetrated with curved grooves 22. Inside the curved grooves 22, a connecting rod group 23 is installed. Outside the connecting rod group 23, a limiting frame 24 is installed. A driving disk 25 is fixedly connected to the side wall of the limiting frame 24. One end of the connecting rod group 23 away from the adjusting disk 21 is fixedly connected to a fixed shell 26. A clamping member 27 is installed on the side wall of the fixed shell 26. A mounting seat 28 is rotatably connected to the surface of the adjusting disk 21. The mounting seat 28 is located at the center position of the surface of the adjusting disk 21. The adjusting disk 21 is threadedly connected to the lamp body 12 through the mounting seat 28.
[0056] It should be noted that the adjusting disk 21 is slidably connected to the connecting rod group 23 through the curved grooves 22, and the connecting rod group 23 is initially located at the end far from the adjusting disk 21. Rectangular grooves are provided on the surface of the limiting frame 24 corresponding to the position of the connecting rod group 23. The connecting rod group 23 is slidably connected to the limiting frame 24 through the rectangular grooves. The clamping member 27 is integrally composed of an elastic curved rod and a rubber pad. The two ends of the elastic curved rod are respectively fixedly connected to the fixed shell 26 and the rubber pad. The connecting rod group 23 is integrally composed of no less than three connecting rods. The three connecting rods are evenly distributed around the center of the adjusting disk 21. The connecting rods in the connecting rod group 23 are of different lengths, and the connecting rods respectively correspond to different parts on the outside of the lamp body 12.
[0057] Specifically, when the device detects the lamp body 12, the staff can install the lamp body 12 on the mounting seat 28, so that one end of the lamp body 12 is stably on the surface of the adjusting disk 21. Subsequently, by rotating the adjusting disk 21, since the adjusting disk 21 is slidably connected to the connecting rod group 23 through the curved grooves 22, the rotating adjusting disk 21 will apply a squeezing force to the connecting rod group 23 through the curved grooves 22, thereby driving the connecting rod group 23 to move together along the rectangular grooves on the surface of the limiting frame 24 until the clamping member 27 at one end of the connecting rod group 23 fits against the outer wall of the lamp body 12.
[0058] In a mechanical system, to keep an object at rest or in a uniform linear motion state, the resultant force acting on the object must be zero. In the context of the lamp body 12 being clamped, through the connection and layout of the connecting rod group 23, an asymmetric multi-dimensional clamping assembly is formed. This clamping assembly can apply forces to the lamp from multiple directions. These forces act together on the lamp body 12. When the lamp body 12 is subjected to external forces, such as gravity and inertial forces, the multi-directional constraint forces exerted by the connecting rod group 23 can cancel out the external forces, making the resultant force on the lamp zero, thus keeping the lamp body 12 at rest, that is, the lamp body 12 will not shake or displace;
[0059] When the lamp body 12 is rotating, due to the change in its speed, including changes in magnitude and direction, inertial forces will be generated. The direction of the inertial force is opposite to the direction of the object's acceleration. In this case, the multi-dimensional clamping exerted by the connecting rod group 23 can resist the inertial forces from different directions. For example, when the lamp body 12 is rotating, a centrifugal inertial force will be generated, and its direction is radially outward. The connecting rod group 23 can apply a force equal in magnitude and opposite in direction to the inertial force in the corresponding direction according to the rotation situation of the lamp body 12 to balance the inertial force, and further make the resultant force on the lamp body 12 zero during rotation, so as to ensure that the lamp body 12 always remains in the set position during rotation. Embodiment
[0060] Based on Embodiment 1, please refer to Figures 7 to 11 As shown, a centering detection mechanism 3 is provided outside the drive module 11. The centering detection mechanism 3 is used to centrally collect and detect the light emitted by the lamp body 12. The centering detection mechanism 3 includes a main control shaft 31 installed above the drive module 11. A detector 32 is installed at one end of the main control shaft 31 away from the drive module 11. A converging frame 33 is installed inside the detector 32. Shading groups 34 are fixedly connected to both side walls of the main control shaft 31;
[0061] It should be noted that the converging frame 33 is integrally composed of no less than four rectangular plates. Every two of the four rectangular plates form a group, and the rectangular plates in each group are installed obliquely in a form with a narrower upper part and a wider lower part. The central positions of the detector 32, the lamp body 12, and the adapter pad 311 are all located in the same vertical plane.
[0062] Specifically, in the design of the converging frame 33, the rectangular plate is installed obliquely in a form that is narrower at the top and wider at the bottom. When the divergent light emitted by the lamp body 12 irradiates the surface of the rectangular plate, the light will be reflected according to the law of reflection. This is because the rectangular plate is installed obliquely, and the normal direction of its surface forms a certain angle with the incident direction of the light. According to the law of reflection, after the light is reflected on the surface of the rectangular plate, its propagation direction will change. By adjusting the inclination angle of the rectangular plate, the light can be reflected towards the direction of the detector 32, thereby gradually converging the light that was originally diverging upward from the lamp body 12 towards the detector 32;
[0063] The emitted light will diverge in all directions during the propagation process. This is due to the characteristics of light traveling in a straight line and scattering. According to the law of light propagation, light travels in a straight line in a uniform medium. However, in the actual environment, due to the characteristics of the light-emitting surface of the lamp body 12 and the influence of the surrounding medium, the light will scatter in all directions. This divergence causes the energy of the light to be dispersed in space, resulting in a decrease in the intensity of the optical signal received by the detector 32;
[0064] The converging frame 33 composed of rectangular plates installed obliquely in a form that is narrower at the top and wider at the bottom can utilize the reflection characteristics of light to gradually guide and converge the divergent light onto the detector 32. From a geometric perspective, the inclined surfaces of multiple rectangular plates form a funnel-like structure. After multiple reflections, the light will gradually gather towards the central area of the converging frame 33. As the light is continuously reflected and converged, the intensity of the optical signal in the area where the detector 32 is located is significantly enhanced. Through the continuous reflection of the symmetrically arranged rectangular plates, more and more light is converged near the detector 32, thereby increasing the intensity of the optical signal received by the detector 32.
[0065] It should be noted that a transmission member 35 is installed on the outer wall of the drive module 11. A support shaft 36 is installed inside the transmission member 35. One end of the support shaft 36 away from the transmission member 35 is fixedly connected to a threaded shaft 37. The outer wall of the threaded shaft 37 is threadedly connected to a threaded collar 38. The outer wall of the threaded collar 38 is fixedly connected to a drive ring 39. Elastic plates 310 are symmetrically installed on the outer wall of the drive ring 39. At a position away from the drive ring 39, the elastic plates 310 are fixedly connected to an adapter pad 311. The transmission member 35 is integrally composed of an upper and a lower pulley and a belt combination. A ball screw structure is formed between the threaded shaft 37 and the threaded collar 38. Bending grooves are provided at positions on the outer wall of the drive ring 39 corresponding to the elastic plates 310. The drive ring 39 and the elastic plates 310 are slidably connected through the bending grooves, and both sides of the adapter pad 311 are made of light-absorbing materials.
[0066] Specifically, since the pulleys in the transmission member 35 are fixedly connected to the output shaft end of the driving motor in the driving module 11 and the support shaft 36 respectively, when the driving module 11 drives the lamp body 12 to rotate and switch the angle, the support shaft 36 will rotate synchronously by relying on the transmission of the belt in the transmission member 35. Since a ball screw structure is formed between the threaded shaft 37 and the threaded collar 38, and the pitch of the outer wall of the threaded shaft 37 is equal to the inner diameter of the threaded collar 38, and at the same time, the tangential of the thread and the cylinder is greater than 45 degrees with respect to the horizontal plane. Therefore, when the threaded shaft 37 rotates, the rotational force on its outer wall can be smoothly transmitted to the threaded collar 38, thereby driving it to move linearly along the outer wall of the threaded shaft 37. Since the driving ring 39 and the elastic plate 310 are slidably connected through the bending groove, when the driving ring 39 moves synchronously with the threaded collar 38, the bending groove on the outer wall of the driving ring 39 will continuously squeeze the elastic plate 310, thereby driving the elastic plate 310 to move according to the inner wall bending degree of the bending groove, so as to drive the adapter pad 311 above the main body bracket 1, and make its two sides flip and move under the position change of the elastic plate 310;
[0067] The introduction of the adapter pad 311 helps to create a stable and uniform detection environment. By absorbing excess light, it provides a reliable detection atmosphere for the detector 32, ensuring the consistency and reliability of each detection result, which is beneficial to improving the detection accuracy and repeatability. Moreover, during the process of the lamp switching angles, the adapter pad 311 can perform intermittent flipping movements through the driving ring 39 below, and then cooperate with the switching of the position and angle of the lamp. Through this design of synchronously flipping and moving to adjust the position, the light-absorbing material on the adapter pad 311 can always be in the best light-absorbing position, and absorb the stray light that may be generated in real time according to different angles of the lamp.
[0068] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
