Technical Field
[0001] The invention relates to the technical field of lamp light intensity detection, and in particular to a continuous light intensity detection device for an LED indoor lamp. Background Art
[0002] The continuous light intensity detection device of LED indoor lamps is a device specially used to measure and evaluate the luminous intensity of LED indoor lamps in a continuous working state. With the widespread application of LED lighting technology, the quality and performance requirements of LED lamps are also increasing. The continuous light intensity detection device plays an important role in ensuring the quality and performance of LED lamps. In the Chinese invention with application publication number CN119124572A, a clamping device for lamp testing is disclosed, including a base, a rotating seat, and a clamping frame. The rotating seat is rotatably arranged on the base around a first rotating axis, and the clamping frame is rotatably arranged on the rotating seat around a second rotating axis. The first rotating axis and the second rotating axis are skewly intersecting. A plurality of clamping members for clamping lamps are slidably arranged on the clamping frame. The clamping members and the clamping frame are connected by elastic members, and the elastic members are used to drive the plurality of clamping members to slide toward the center of the clamping frame. The clamping device for lamp testing of the present invention can change a plurality of different angles of the lamp clamped on the clamping frame through the rotational cooperation of the rotating seat and the clamping frame, and can perform light intensity detection in a plurality of different directions, and the detection of the light intensity of the lamp is very comprehensive. However, the equipment in the referenced document still has the following defects when used in practice: 1. Compared with the device in the reference document, the lamp clamped on the clamping frame can be changed to multiple different angles through the rotation cooperation of the rotating seat and the clamping frame, and the light intensity detection in multiple different directions can be performed. At the same time, the multiple clamping members on the clamping member can switch the clamping surfaces of different shapes to adapt to the clamping of lamps with different side shapes, and the clamping range of the multiple clamping members can be adjusted; In actual use, when a symmetrical fixture is used to clamp the lamp, the lamp can only be limited in a single dimension, and the constraints in other directions are relatively weak. Therefore, when the lamp is rotating, in addition to the limited dimension, forces in other directions, such as gravity and inertia, will affect the lamp. In addition, 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, since the fixture can only provide a single-dimensional limit, the center of gravity of the lamp will deviate from the support point as the rotation angle changes, causing the center of gravity of the lamp to be unstable during rotation. The unstable center of gravity causes the lamp to shake or tilt during rotation, resulting in uncontrollable changes in the light angle and direction of the lamp, which will directly affect the light intensity signal received by the light intensity detector, resulting in large errors in the measurement results and unable to accurately reflect the actual light intensity distribution of the lamp at various angles; 2. Moreover, this symmetrical structure, while ensuring the stability of the lamp clamping, also brings about the problem of light blocking. 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; Due to the blocking of light by the fixture, the detector cannot receive the complete light intensity signal of the lamp at certain angles, which will lead to the loss of light intensity distribution measurement data and the inability to accurately draw the complete light intensity distribution curve of the lamp. For example, when measuring the light intensity of the side of the lamp, if the fixture blocks part of the light, 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 that angle; 3. Finally, the device in the referenced document can adapt to clamping lamps with different side shapes by switching the clamping surfaces of different shapes. The clamping range of multiple clamps can be adjusted to facilitate the clamping of lamps of different sizes. In actual operation, a series of operation steps are required to switch the clamping surfaces to adapt to lamps of different shapes. Moreover, after each switching of the clamping surface, the clamping position and angle need to be recalibrated to ensure the accurate and stable position of the lamp during the detection process. Switching the clamping surface back and forth will cause the clamping parts to wear and loosen, thereby affecting the stability of the clamping. When the clamping is unstable, the lamp will move or shake slightly during the detection process, thereby affecting the accuracy of the detection results. In view of this, the present invention proposes a continuous light intensity detection device for an LED indoor lamp to make up for and improve the deficiencies of the prior art.

[0008] Furthermore, the clamping member is composed of an elastic curved rod and a rubber pad as a whole, and two ends of the elastic curved rod are fixedly connected to the fixed shell and the rubber pad respectively.
[0009] Furthermore, the connecting rod group as a whole is composed of a combination of no less than three connecting rods, the three connecting rods are evenly distributed around the center of the adjustment disk, the connecting rods in the connecting rod group are of different lengths, and the connecting rods correspond to different parts of the outside of the lamp body.
[0010] Furthermore, a focusing detection mechanism is provided on the outside of the driving module, and the focusing detection mechanism is used to collect the light emitted by the lamp body and then detect it. The focusing detection mechanism includes a main control shaft installed above the driving module, and a detector is installed at the end of the main control shaft away from the driving module. A focusing frame is installed inside the detector, and both side walls of the main control shaft are fixedly connected with a shading group.
[0011] Furthermore, the gathering frame is composed of a combination of no less than four rectangular plates, and each of the four rectangular plates is a group of two. The rectangular plates in each group are installed obliquely in the form of being narrow at the top and wide at the bottom. The center positions of the detector, the lamp body and the adapter pad are all located on the same vertical plane.
[0012] Furthermore, a transmission member is installed on the outer wall of the driving module, a support shaft is installed inside the transmission member, an end of the support shaft away from the transmission member is fixedly connected to a threaded shaft, an outer wall of the threaded shaft is threadedly connected to a threaded ring, an outer wall of the threaded ring is fixedly connected to a driving ring, an elastic plate is symmetrically installed on the outer wall of the driving ring, and an adapter pad is fixedly connected to the elastic plate at a position away from the driving ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The device adopts an asymmetric multi-dimensional clamping method by introducing a connecting rod group. Through the connection and layout of the connecting rod group, a stable restraining force can be applied to the lamp from multiple directions, thereby providing support force on the axial direction and other inclined directions of the lamp. When the lamp is subjected to 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 the lamp generates inertial force during rotation, the clamping assembly can resist the inertial force from different directions to ensure that the lamp always remains in the set position during rotation without shaking or displacement. Compared with the existing technology that can only provide position limiting 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. This design effectively resists the influence of external forces such as gravity and inertia on the lamp during rotation, ensuring that the center of gravity of the lamp can be kept stable at any rotation angle, avoiding shaking or tilting. More 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 propagation path of the light, so that the detector can receive the complete light intensity signal of the lamp at all angles, thereby accurately drawing the complete light intensity distribution curve of the lamp, truly reflecting the light intensity of the lamp at different angles, and effectively improving the accuracy and reliability of light intensity detection; Among them, the clamping piece can provide a certain elastic support when it fits the outside of the lamp. In the process of clamping the lamp, this elastic support can better enable the rubber pad in the clamping piece to change its 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 of the lamp during the rotation process, avoiding damage to the lamp due to excessive force, and further improving the safety and stability of the lamp during the inspection process. Among them, the device adopts a similar three-point clamping method. From the perspective of high triangle stability, this clamping method has higher stability. During the rotation of the lamp, the 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, the three-point clamping can also better adapt to the changes in the center of gravity of lamps of different shapes and sizes, thereby improving the versatility and adaptability of the device. This device can accurately control the distance between the light source and the detector by ensuring that the position of the detector remains unchanged and only changing the detection position of the lamp. No matter how the angle or position of the lamp changes, the detector is always in a fixed position, thereby ensuring that the distance from the light source to the detector remains consistent during each measurement, thereby making the measurement result more accurate and reliable, and being able to truly reflect the light intensity distribution of the lamp at various angles; What is particularly important is that a gathering 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 the form of being narrow at the top and wide at the bottom, which can effectively gather the light emitted locally by the lamp. When the lamp is emitting light, the light will diverge in all directions during the propagation process, resulting in a weakening of the intensity of the light signal received by the detector. The special structure of the gathering frame can change the propagation direction of the light, gather the originally divergent light onto the detector, increase the intensity of the light signal received by the detector, and then enable the detector to receive a stronger light signal, thereby improving the sensitivity and accuracy of the detection; Among them, the shading group is also installed at an angle on both sides of the detector, which can block the interference of external stray light to a certain extent. In the actual detection environment, there will be various light sources and reflectors around, which will generate stray light and affect the detector's accurate measurement of the light intensity of the lamp. The shading group structure can form a relatively closed 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 results; This device can effectively absorb stray light from all directions by setting the other side of the illumination as the shadow side and adopting a light-absorbing and anti-reflective design on both sides of the adapter pad. When the main body of the lamp emits light, part of the light will shine on other parts inside the device and reflect. If there is no light-absorbing material, part of these reflected lights will enter the detector, causing the light signal received by the detector to contain stray light components, making the measurement result high and inaccurate. The light-absorbing material can absorb these stray lights and ensure that the detector receives mainly the light directly emitted by the main body of the lamp, thereby improving the accuracy of light intensity detection; The introduction of the adapter pad helps to create a stable and uniform detection environment. By absorbing excess light, it provides a reliable detection atmosphere for the detector, ensuring the consistency and reliability of each test result, which is conducive to improving the accuracy and repeatability of the test. What is particularly important is that during the angle switching process of the lamp, the adapter pad can intermittently flip through the driving ring below to coordinate with the switching of the lamp position angle. Through this synchronous flipping motion to adjust the position design, the light-absorbing material on the adapter pad can always be in the best light-absorbing position, and absorb the possible stray light in real time according to the different angles of the lamp. When the lamp body is rotated to a certain angle, the adapter pad will flip to the appropriate position accordingly to ensure that its light-absorbing material can effectively absorb the scattered light and reflected light generated by the lamp at that angle, further reducing the interference of stray light on light intensity detection; In addition, different types of lamps or different detection requirements require lamps to perform light intensity detection at different angles, and the adapter pad can flip synchronously with the change of the lamp position angle, so that the device can adapt to various complex detection scenarios and lamp types. No matter how the angle of the lamp changes, the adapter pad can adjust its position in time to ensure the consistency and effectiveness of the light absorption effect, thereby improving the versatility and flexibility of the device. 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 a synchronous flipping motion through the coordinated action of components such as the drive ring, threaded shaft, and threaded collar. The movements of each component cooperate with each other to avoid device instability or structural looseness caused by the movement of a single component. This coordinated movement 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.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] Please refer to Figure 1 to Figure 2 As shown, a continuous light intensity detection device for an LED indoor lamp is used to perform light intensity detection on a lamp body 12, including a main body bracket 1, a driving module 11 is installed above the main body bracket 1, and a multi-dimensional limiting mechanism 2 is arranged above the main body bracket 1, and 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.
[0020] Please refer to Figures 2 to 6As shown, the multi-dimensional limiting mechanism 2 includes an adjusting disk 21 installed on the outside of the driving module 11, and the surface of the adjusting disk 21 is evenly penetrated with curved grooves 22, and a connecting rod group 23 is installed inside the curved groove 22, and a limiting frame 24 is installed outside the connecting rod group 23, and a driving disk 25 is fixedly connected to the side wall of the limiting frame 24, and one end of the connecting rod group 23 away from the adjusting disk 21 is fixedly connected to a fixed shell 26, and a clamping member 27 is installed on the side wall of the fixed shell 26. The surface of the adjusting disk 21 is rotatably connected to a mounting seat 28, and the mounting seat 28 is located at the center of the surface of the adjusting disk 21. The adjusting disk 21 and the lamp body 12 are threadedly connected through the mounting seat 28; It should be noted that the adjusting disk 21 and the connecting rod group 23 are slidably connected through the curved groove 22, and the connecting rod group 23 is initially located at the end away from the adjusting disk 21, a rectangular groove is provided on the surface of the limiting frame 24 at the position corresponding to the connecting rod group 23, and the connecting rod group 23 and the limiting frame 24 are slidably connected through the rectangular groove, the clamping member 27 is composed of a combination of an elastic curved rod and a rubber pad, and the two ends of the elastic curved rod are respectively fixedly connected to the fixed shell 26 and the rubber pad, and the connecting rod group 23 is composed of a combination of no less than three connecting rods, and the three connecting rods are evenly distributed at the center of the adjusting disk 21. The connecting rods in the connecting rod group 23 are of different lengths, and the connecting rods correspond to different parts of the outside of the lamp body 12.
[0021] Specifically, when the device is used to detect 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 stabilized on the surface of the adjustment disk 21, and then the adjustment disk 21 is rotated. Since the adjustment disk 21 and the connecting rod group 23 are slidably connected through the curved groove 22, the rotating adjustment disk 21 will apply a squeezing force to the connecting rod group 23 through the curved groove 22, thereby driving the connecting rod group 23 to gather and move along the rectangular groove on the surface of the limit frame 24 until the clamping piece 27 at one end of the connecting rod group 23 is attached to the outer wall of the lamp body 12; In a mechanical system, to keep an object still or in a uniform linear motion state, the resultant force on the object must be zero. In the case of clamping the lamp body 12, an asymmetric multi-dimensional clamping assembly is formed through the connection and layout of the connecting rod group 23. 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, gravity, and inertia, the multi-directional constraint forces applied by the connecting rod group 23 can offset the external forces, so that the resultant force on the lamp is zero, thereby keeping the lamp body 12 in a stationary state, that is, the lamp body 12 will not shake or move. When the lamp body 12 is rotating, due to the change in its speed, including the change in size and direction, an inertial force is generated, and the direction of the inertial force is opposite to the direction of the object's acceleration. In this case, the multi-dimensional clamping applied by the connecting rod group 23 can resist the inertial force from different directions. For example, when the lamp body 12 rotates, a centrifugal inertial force is generated, and its direction is radially outward. The connecting rod group 23 can apply a force equal to the inertial force and opposite to the inertial force in the corresponding direction according to the rotation of the lamp body 12 to balance the inertial force, thereby making the resultant force on the lamp body 12 during the rotation process zero, thereby ensuring that the lamp body 12 always remains in the set position during the rotation process. Example
[0022] Based on Example 1, please refer to Figures 7 to 11 As shown, a focusing detection mechanism 3 is arranged outside the driving module 11, and the focusing detection mechanism 3 is used to focus and collect the light emitted by the lamp body 12 and then detect it. The focusing detection mechanism 3 includes a main control shaft 31 installed above the driving module 11, and a detector 32 is installed at one end of the main control shaft 31 away from the driving module 11. A focusing frame 33 is installed inside the detector 32, and both side walls of the main control shaft 31 are fixedly connected with a shading group 34; It should be noted that the gathering frame 33 is composed of a combination of no less than four rectangular plates, and each of the four rectangular plates is a group of two. The rectangular plates in each group are installed at an angle in the form of being narrow at the top and wide at the bottom. The center positions of the detector 32, the lamp body 12 and the adapter pad 311 are all located on the same vertical plane.
[0023] Specifically, in the design of the gathering frame 33, the rectangular plate is installed obliquely in the form of being narrow at the top and wide 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. Through the inclination angle of the rectangular plate, the light can be reflected toward the direction of the detector 32, thereby causing the light originally diverging upward from the lamp body 12 to gradually converge toward the detector 32. The emitted light will diverge in all directions during the propagation process. This is because light has the characteristics of rectilinear propagation and scattering. According to the propagation law of light, light propagates in a straight line in a uniform medium. However, in an 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, so that the intensity of the light signal received by the detector 32 is weakened. The gathering frame 33 composed of rectangular plates installed obliquely in a narrow upper and wide lower form can utilize the reflection characteristics of light to gradually guide and converge the divergent light to the detector 32. From a geometric point of view, the inclined surfaces of multiple rectangular plates form a funnel-like structure. After multiple reflections, the light will gradually gather to the central area of the gathering frame 33. As the light is continuously reflected and converged, the light signal intensity in the area where the detector 32 is located is significantly enhanced. After continuous reflection by the symmetrically arranged rectangular plates, more and more light is converged near the detector 32, thereby increasing the light signal intensity received by the detector 32.
[0024] It should be noted that a transmission member 35 is installed on the outer wall of the driving module 11, and a support shaft 36 is installed inside the transmission member 35. A threaded shaft 37 is fixedly connected to the end of the support shaft 36 away from the transmission member 35. A threaded ring 38 is threadedly connected to the outer wall of the threaded shaft 37. A driving ring 39 is fixedly connected to the outer wall of the threaded ring 38. An elastic plate 310 is symmetrically installed on the outer wall of the driving ring 39. An adapter pad 311 is fixedly connected to the position of the elastic plate 310 away from the driving ring 39. The transmission member 35 as a whole is composed of an upper and lower pulley and a belt combination. A ball screw structure is formed between the threaded shaft 37 and the threaded ring 38. Bending grooves are provided on the outer wall of the driving ring 39 at the position corresponding to the elastic plate 310. The driving ring 39 and the elastic plate 310 are slidingly connected through the bending grooves, and both sides of the adapter pad 311 are set to light-absorbing materials.
[0025] Specifically, since the pulley in the transmission member 35 is fixedly connected to the output shaft end of the driving motor in the driving module 11 and the support shaft 36, when the driving module 11 drives the lamp body 12 to rotate and switch the angle, the support shaft 36 will rotate synchronously 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 the angle between the tangent of the thread and the cylinder and the horizontal plane is greater than 45 degrees, when the threaded shaft 37 keeps rotating, The rotational force of 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 curved groove, when the driving ring 39 moves synchronously with the threaded collar 38, the curved 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 curvature of the inner wall of the curved groove, thereby driving the adapter pad 311 above the main bracket 1, so that both sides of it can flip and move under the change of the position of the elastic plate 310; 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 accuracy and repeatability of the detection. In addition, during the angle switching of the lamp, the adapter pad 311 can perform intermittent flipping movements through the drive ring 39 below, and then cooperate with the switching of the lamp position angle. Through this synchronous flipping movement to adjust the position design, the light-absorbing material on the adapter pad 311 can always be in the best light-absorbing position, and according to the different angles of the lamp, it can absorb the possible stray light in real time.
