Abstract
Description
Technical Field
[0001] This utility model relates to the field of distributed light source lighting technology, and in particular to a lighting device based on an umbrella-shaped structure. Background Technology
[0002] While traditional distributed lighting systems can achieve multi-area illumination coverage in specific scenarios, their design concepts and control methods still have shortcomings. Distributed lighting systems often use fixed lamp arrays or fixed lighting modules, thus relying too heavily on external supports or complex wiring. This results in traditional distributed lighting systems being bulky and heavy, unable to be easily stored and adapted to dynamic scenarios. Furthermore, traditional distributed lighting systems rely on experience-based design, making it easy for point light sources to create shadows in complex environments due to their fixed angles, requiring significant compensation for dynamic light intensity. Additionally, traditional distributed lighting systems require additional wiring and support installations, necessitating disassembly and repair of each lamp and wiring during maintenance, consuming considerable time and effort.
[0003] Based on the characteristics of distributed light sources, due to the presence of supports and auxiliary devices, distributed light sources can only be built by selecting locations based on experience, and cannot be moved freely after being built. Consequently, the light source control scheme can only rely on algorithms. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a lighting device based on an umbrella-shaped structure. It improves upon traditional distributed light source optimization methods to overcome the limitations of traditional light sources. This device can be mounted on a multi-degree-of-freedom robotic arm, leveraging the arm's flexible movement capabilities to enhance the overall performance of the distributed light source. The device incorporates a dynamic supplementary lighting algorithm, which calculates the difference between the opening angle of the lighting bracket, the constantly changing light field conditions, and the ideal conditions, thereby continuously adjusting the lighting intensity to achieve dynamic supplementary lighting. Specifically, it includes:
[0005] A lighting device based on an umbrella-shaped structure includes: a lighting device,
[0006] The lighting device includes a main support column, a collar, a light source mounting assembly, a servo motor, and a light source body;
[0007] The collar is fitted onto the main support column and supports vertical movement along the main support column;
[0008] The top sidewall of the main support column has a plurality of hinge lugs evenly arranged around its circumference.
[0009] The outer side wall of the collar is uniformly arrayed with ears, and the mounting ears of the collar correspond to the hinge ears on the main support.
[0010] Each light source mounting assembly is installed on the main support and collar via corresponding hinges and mounting ears;
[0011] The light source is mounted on the light source mounting assembly, and the servo motor is connected to the light source;
[0012] When the collar moves upward along the main support column, the light source mounting assembly drives the light source to move away from the main support column; when the collar moves downward along the main support column, the light source mounting assembly drives the light source to move closer to the main support column.
[0013] Optionally, the mounting arm is a rectangular groove, and a cover plate that supports disassembly is provided on the upper surface of the rectangular groove in the axial direction; a through groove is provided at the bottom of the end of the rectangular groove away from the main support column, and the light beam of the light source passes through the through groove.
[0014] The servo motor is mounted on the side wall of the rectangular through slot. The output end of the servo motor passes through the side wall of the rectangular through slot and is connected to the light source. The servo motor supports the rotation of the light source toward the main support column or toward the direction away from the main support column.
[0015] Optionally, the number of mounting ears is equal to the number of hinged ears, and the lighting device further includes a base on which the bottom of the main support is mounted.
[0016] Optionally, the lighting device further includes a connecting base, which is vertically disposed on the base and supports connection to a robotic arm.
[0017] The above technical solution has at least the following advantages compared with the existing technology:
[0018] This invention addresses the problems of traditional distributed light source structures, such as their inability to be freely stored and adapted to dynamic scenes, complex structures hindering maintenance, and lack of mobility for better illumination. It designs a distributed light source lighting device with a light intensity compensation algorithm that can be installed on a multi-degree-of-freedom robotic arm. This design allows for free storage and expansion of the distributed light source, better adapting to dynamic scenes. The addition of a maintenance cover facilitates easy inspection and maintenance of the device structure and control circuitry. Furthermore, the addition of a compatible connector allows the entire device to be installed on a multi-degree-of-freedom robotic arm, maximizing the lighting advantages of the distributed light source. Considering the multiple factors involved in compensating for the difference between the current light intensity and the ideal light intensity, a light intensity compensation control scheme is established. By acquiring current light intensity data and pre-set ideal light intensity data, a superior light intensity compensation effect is achieved, enabling the auxiliary equipment to perform precise light intensity compensation as the light intensity changes.

[0029] like Figures 1 to 4 As shown, a lighting device based on an umbrella-shaped structure includes: a lighting device,
[0030] The lighting device includes a main support column 3, a collar 4, a light source mounting assembly, a servo motor 7, and a light source 6 body. The collar 4 is fitted onto the main support column 3 and supports vertical movement along the main support column 3. Multiple hinge ears 9 are evenly arrayed around the top sidewall of the main support column 3. Mounting ears 10 are evenly arrayed around the outer sidewall of the collar 4, and the mounting ears 10 of the collar 4 correspond to the hinge ears 9 on the main support column 3. Each light source mounting assembly is mounted on the main support column 3 and the collar 4 via corresponding hinge ears 9 and mounting ears 10. The light source 6 is mounted on the light source mounting assembly, and the servo motor 7 is connected to the light source 6. When the collar 4 moves upward along the main support column 3, the light source mounting assembly drives the light source 6 to move away from the main support column 3; when the collar 4 moves downward along the main support column 3, the light source mounting assembly drives the light source 6 to move closer to the main support column 3.
[0031] The light source mounting assembly includes: a servo motor 7, a mounting arm 11, and a connecting rod 5; one end of the mounting arm 11 is rotatably connected to a corresponding hinge lug 9 on the main support column 3, and the mounting arm 11 supports up-and-down rotation around the hinge point between the mounting arm 11 and the main support column 3; a servo motor 7 is mounted on the other end of each mounting arm 11, and a light source 6 is provided at the output end of the servo motor 7 and installed inside the mounting arm 11; one end of the connecting rod 5 is hinged to the middle of the mounting arm 11, and the other end of the connecting rod 5 is hinged to the mounting lug 10 of the corresponding collar 4; when the collar 4 moves upward, the connecting rod 5 pushes the mounting arm 11 to rotate upward; when the collar 4 moves downward, the connecting rod 5 pulls the mounting arm 11 to rotate downward.
[0032] The mounting arm 11 is a rectangular slot, and a removable cover plate is provided on the upper surface of the rectangular slot in the axial direction. A through slot is provided at the bottom of the end of the rectangular slot away from the main support column 3, through which the light beam of the light source 6 passes. The servo motor 7 is mounted on the side wall of the rectangular through slot, and its output end passes through the side wall of the rectangular through slot and connects to the light source 6. The servo motor 7 supports rotating the light source 6 towards the main support column 3 or away from the main support column 3. The number of mounting ears 10 is equal to the number of hinge ears 9. The lighting device also includes a base 1, on which the bottom of the main support column 3 is mounted. The lighting device also includes a connecting seat 2, which is vertically mounted on the base 1 and supports connection to the robotic arm.
[0033] The specific structure of the lighting device of this utility model is as follows:
[0034] This device includes a base 1 and a connecting seat 2. The base 1 and the connecting seat 2 can be selected according to requirements. One of the bases is connected to a robotic arm (the robotic arm is existing technology, meaning that this device can be mounted on a robotic arm that can rotate or move with multiple degrees of freedom, so that this device also moves to the target). The robotic arm can be a six-degree-of-freedom or other multi-degree-of-freedom robotic arm. The connecting seat 2 is set on the base 1 and is vertically set on the upper surface of the base 1.
[0035] The main support column 3 is a hollow cylinder, and the main support column 3 is vertically installed on the base 1.
[0036] The bottom of the main support column 3 and the base 1 can be connected by threads or assembled together by bolts or other connection methods.
[0037] Multiple hinged ears 9 are evenly arranged around the top of the main support column 3, such as 6, 8 or 10, or other numbers.
[0038] The collar 4 is also a hollow cylinder, but it can be fitted onto the main support column 3 and move up and down along it. Furthermore, the collar 4 has positioning holes 8. When the collar 4 moves to a suitable height, there can be multiple positioning holes 8. By screwing bolts into the positioning holes 8, the collar 4 is fixed in place against the outer wall of the main support column 3. Therefore, the collar 4, through the positioning holes 8 and the bolts, can be fixedly installed on the main support column 3 at any height, thereby controlling the extension degree of the mounting arm 11 of the device.
[0039] Mounting arms 11 are evenly installed around the main support column 3. Therefore, if there are two mounting arms 11, the angle between the two mounting arms 11 is 180 degrees. If there are six mounting arms 11, the angle between adjacent mounting arms 11 is 60 degrees. That is, the corresponding hinge lug 9 is selected to install one end of the mounting arm 11. The number of mounting arms 11 is generally set according to the requirements.
[0040] Each mounting arm 11 is paired with a connecting rod 5 to drive the extension of the mounting arm 11. One end of the connecting rod 5 is mounted on the collar 4, and the other end of the connecting rod 5 is mounted on the lower middle part of the mounting arm 11.
[0041] Furthermore, the base 1 has anti-collision guard edges on both sides.
[0042] Further, a reinforcing rib is provided between one side of the bottom cylindrical portion of the main support column 3 and the base 1.
[0043] Furthermore, the connector 2 supports the provision of six screw holes, which are distributed in a regular hexagonal pattern.
[0044] Further defined, the collar 44 has several hinge structures with a connecting screw hole and a limiting screw hole evenly distributed on its outer side, and the collar 44 can be fitted on the main support column 32 and can slide freely up and down along the main support column 32.
[0045] Further specifying, the connecting rod 5 is in the shape of a flat, elongated rod, with hinged structures at both ends.
[0046] When using this device, the number of mounting arms 11 is set according to the requirements, and the extension degree of the robotic arms is adjusted according to the requirements. After all adjustments are made, it may be necessary to make a fine adjustment to the angle of each light source 6, which drives the corresponding servo motor 7 of the light source 6. The servo motor 7 can adjust the illumination angle of the light source 6.
[0047] This invention addresses the problems of traditional distributed light source 6 structures, such as their inability to be freely stored and adapted to dynamic scenes, complex structures hindering maintenance, and inability to be moved for better illumination. It designs a distributed light source 6 lighting device with a light intensity compensation algorithm that can be installed on a multi-degree-of-freedom robotic arm. This design allows the distributed light source 6 to be freely stored and expanded, better adapting to dynamic scenes. The addition of a maintenance cover makes the device structure and control circuitry extremely convenient for inspection and maintenance. The addition of a matching connector 2 allows the entire device to be installed on a multi-degree-of-freedom robotic arm, maximizing the illumination advantages of the distributed light source 6. Furthermore, considering the multiple factors involved in compensating for the difference between the current light intensity and the ideal light intensity, a light intensity compensation control scheme is established. By acquiring current light intensity data and pre-set ideal light intensity data, a superior light intensity compensation effect is achieved, assisting the equipment in performing precise light intensity compensation as the light intensity changes.
