Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to an underwater array light source. Background Technology

[0002] Underwater light sources are a type of underwater lighting equipment. For example, diving flashlights were originally used only for lighting divers, but as people's interest in the ocean has grown, and with the exploration of underwater ancient artifacts, national marine geographical surveys, and the latest trend of underwater wedding photography, underwater cameras have been widely used on the seabed, which has driven the development of underwater photography lighting, and at the same time, the requirements for underwater light sources have become increasingly higher.

[0003] Currently, the vast majority of light sources used in underwater robots are point light sources, with no area light sources available. The main reason is that area light sources create significant drag underwater, greatly affecting the movement and attitude control of the underwater robot. Point light sources, on the other hand, have limited power per point, resulting in a smaller illumination range and brightness. For objects illuminated by point light sources, under the same power and fixed projection distance conditions: parallel light provides high brightness but a small effective projection area; while diffused light increases the projection area, the unit brightness decreases drastically, making it difficult to meet the requirements for long-distance illumination and imaging. Summary of the Invention

[0004] To meet the requirements of long-distance illumination and imaging, this application provides an underwater array light source.

[0005] The underwater array light source provided in this application adopts the following technical solution: An underwater array light source includes several individual light sources, several light source mounting bases, and several connecting bridges. The individual light sources are disposed on the light source mounting bases. Both ends of each connecting bridge are connected to the light source mounting bases. Several connecting bridges are connected around the periphery of the light source mounting bases. The light source mounting bases and the connecting bridges are combined to form a mesh structure.

[0006] Optionally, the light source mounting base and the connecting bridge are combined to form a honeycomb-shaped equilateral hexagonal structure.

[0007] By adopting the above technical solution, the light source mounting base and the connecting bridge are connected to form a honeycomb equilateral hexagonal structure. Individual light sources are then installed on the light source mounting base, and the individual light sources are combined into a light source array, which can provide large-area illumination and ensure sufficient underwater light, thereby meeting the requirements for long-distance lighting and imaging. At the same time, the honeycomb equilateral hexagonal structure formed by the individual light sources and the connecting bridge can greatly reduce the resistance of water flow to the underwater light source array by pushing the light source array underwater.

[0008] Optionally, one end of the water-facing side of the light source mounting base is circular, and one end of the water-repellent side of the light source mounting base is a flow guide tail cone, and the light source mounting base as a whole is streamlined.

[0009] By adopting the above technical solution, when the light source mounting base is pushed in the water, the water-facing end of the light source mounting base is circular, and the water-repellent end includes a guide tail cone. The overall structure of the light source mounting base is streamlined, which makes the resistance at the water-facing end of the light source mounting base smaller, and the eddy current generated at the water-repellent end is also smaller, further reducing the resistance of the underwater array light source.

[0010] Optionally, the backwater side of the connecting bridge is recessed towards the water-facing side to form an arched bridge opening, and the connecting bridge has a biomimetic arched truss structure.

[0011] By adopting the above technical solution, the connecting bridge is set as a biomimetic arched truss structure. The arched truss structure can improve the strength between the two light source mounting bases connected by the connecting bridge and improve the stability of the underwater array light source structure. At the same time, the biomimetic honeycomb equilateral hexagonal structure has the characteristic of parallelizing the water flow passing through it, which can parallelize the turbulent water flow and make the underwater robot connected to the underwater array light source more stable in posture.

[0012] Optionally, the water-facing side of the connecting bridge is recessed towards the water-repellent side to form an arc-shaped bridge surface, and the water-facing side of the connecting bridge is arc-shaped from the middle to both sides, and the water-facing side of the connecting bridge is streamlined.

[0013] By adopting the above technical solution, when the connecting bridge moves underwater, the streamlined shape of the water-facing side of the connecting bridge reduces the resistance of the water flow to the connecting bridge, thereby further reducing the resistance to the underwater array light source.

[0014] Optionally, the single light source includes a pressure-bearing cylinder, a lens group, an illumination source, and a drive assembly. The pressure-bearing cylinder is mounted on the light source mounting base, the lens group is mounted at the end of the pressure-bearing cylinder, the illumination source is mounted inside the pressure-bearing cylinder, and the illumination source refracts light to the outside through the lens group. The drive assembly is mounted inside the pressure-bearing cylinder and is used to drive the illumination source to move in order to adjust the emission angle of the light from the illumination source.

[0015] By adopting the above technical solution, when it is necessary to adjust the emission angle of each lighting source, its internal drive assembly drives the lighting source to move relative to the lens group. By changing the position of the lighting source, the divergence angle of the output light can be adjusted, enabling various light output modes such as converging light, parallel light, and diverging light. Multiple individual light sources, combined through a biomimetic honeycomb equilateral hexagonal truss structure, can achieve effective illumination surfaces at different underwater distances and different illumination effects under the effect of converging light at different focal points.

[0016] Optionally, the end of the water-facing side of the light source mounting base is provided with a mounting groove, and the individual light source is sealed and disposed in the mounting groove.

[0017] By adopting the above technical solution, the individual light source is installed in the mounting groove, which facilitates the installation and fixation of the individual light source, and also seals the individual light source to reduce water ingress into it. The individual light source is better protected by being wrapped by the light source mounting base.

[0018] Optionally, a reinforcing rod is connected between the two light source mounting bases connected by the connecting bridge, and the reinforcing rod is located on the side of the connecting bridge away from the water-facing side.

[0019] By adopting the above technical solution, since there is a reinforcing rod connecting the two light source mounting bases connected by the connecting bridge, and the reinforcing rod is located on the side of the connecting bridge away from the water-facing side, the connection strength between the two light source mounting bases is stronger, thereby further improving the stability of the underwater array light source structure.

[0020] Optionally, the light source mounting base is provided with a wiring groove, and the reinforcing rod is provided with a wiring groove. The two ends of the wiring groove are respectively connected to the wiring groove. The wiring groove and the wiring groove are provided with wires, which are electrically connected to the individual light source, providing energy to the individual light source and transmitting control signals at the same time. By adopting the above technical solution, a wiring groove is set in the light source mounting base, and a wiring groove is set in the reinforcing rod. The wires are installed in the wiring groove and the wiring groove, and then the wires are connected to the individual light source. This reduces the erosion of the wires by the current, and on the other hand, it can prevent objects in the water from snagging on the wires, which is beneficial to protecting the wires.

[0021] Optionally, the light source mounting base includes multiple streamlined structural blocks, which are sequentially spliced ​​together to form a ring around the light source mounting base. The number of streamlined structural blocks is twice the number of connecting bridges. Each connecting bridge includes two side bridges, which are spliced ​​together to form a connecting bridge. Each reinforcing rod includes two side rods, which are spliced ​​together to form a reinforcing rod. The number of side rods and side bridges connected to the same light source mounting base is the same as the number of streamlined structural blocks. Each side rod and each streamlined structural block is connected in a one-to-one correspondence. Each side bridge and each streamlined structural block is also connected in a one-to-one correspondence.

[0022] By adopting the above technical solution, since the mesh structure of the underwater array light source is formed by splicing together multiple streamlined structural blocks, multiple side bridges, and multiple side rods, the number of individual light sources to be assembled is set according to the underwater exploration situation. The streamlined structural blocks are spliced ​​into the required number of light source mounting bases, and then the individual light sources are installed on the light source mounting bases. The underwater array light source adopts a detachable splicing method, which makes it convenient to adjust the size of the underwater array light source, and also makes it convenient to disassemble and assemble the underwater array light source.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Connect the light source mounting base and the connecting bridge to form a honeycomb equilateral hexagonal structure. Then, install individual light sources on the light source mounting base. The individual light sources are combined into a light source array, which can provide wide-area illumination and ensure sufficient underwater light, thereby meeting the requirements for long-distance illumination and imaging. At the same time, the honeycomb equilateral hexagonal structure formed by the individual light sources and the connecting bridge can greatly reduce the resistance of water flow to the underwater light source array when pushing the light source array underwater. 2. When the light source mounting base is pushed in the water, the water-facing end of the light source mounting base is round and the water-repellent end is pointed. The overall structure of the light source mounting base is streamlined. Because of the streamlined shape, the water-facing end of the light source mounting base has less resistance and the eddy current generated at the water-repellent end is also smaller, which further reduces the resistance of the underwater array light source moving forward. 3. When it is necessary to adjust the emission angle of the lighting source, the drive assembly drives the lighting source to move relative to the lens group. By changing the position of the lighting source, the divergence angle of the output light can be adjusted, enabling various light output modes such as converging light, parallel light, and diverging light, thus making it more versatile.

[0034] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0035] This application discloses an underwater array light source.

[0036] Example 1 Reference Figure 1 and Figure 2The underwater array light source includes several individual light sources 1, several light source mounting bases 2, and several connecting bridges 3. Each end of a connecting bridge 3 is connected to a light source mounting base 2. Three connecting bridges 3 are connected to the periphery of each light source mounting base 2. The three connecting bridges 3 are of equal length and are evenly distributed around the light source mounting base 2. The included angle between two adjacent connecting bridges 3 is 120°. The six light source mounting bases 2 and the six connecting bridges 3 form a regular hexagon. The combination of several light source mounting bases 2 and several connecting bridges 3 forms a honeycomb equilateral hexagonal structure. When the mesh structure moves underwater, the resistance of the water flow is small.

[0037] Reference Figure 1 and Figure 2 The light source mounting base 2 includes six streamlined structural blocks 23 of the same size, which are sequentially assembled into a circle to form the light source mounting base 2. The connecting bridge 3 includes two side bridges 31, which are spliced ​​together to form the connecting bridge 3. The three connecting bridges 3 connected to the same light source mounting base 2 have a total of six side bridges 31, which are integrally formed on the outer peripheral surface of the six streamlined structural blocks 23. The connecting bridge 3 connects two light source mounting bases 2. There are reinforcing rods 4 connecting the light source mounting base 2. Three reinforcing rods 4 are connected around the same light source mounting base 2. The three reinforcing rods 4 are evenly distributed around the light source mounting base 2. The three reinforcing rods 4 correspond one-to-one with the three connecting bridges 3. The reinforcing rods 4 are located on the side of the connecting bridge 3 away from the water-facing side. The reinforcing rod 4 includes two side rods 42. The two side rods 42 are spliced ​​together to form the reinforcing rod 4. There are a total of six side rods 42 connected to the three reinforcing rods 4 of the same light source mounting base 2. The six side rods 42 are integrally formed on the outer peripheral surface of the six streamlined structural blocks 23.

[0038] Since the honeycomb-shaped equilateral hexagonal structure of the underwater array light source is formed by splicing together multiple streamlined structural blocks 23, multiple side bridges 31 and multiple side rods 42, the number of individual light sources 1 to be assembled is set according to the underwater exploration situation. The streamlined structural blocks 23 are spliced ​​together to form the required number of light source mounting bases 2, and then the individual light sources 1 are installed on the light source mounting bases 2. The underwater array light source adopts a detachable splicing method, which makes it convenient to adjust the size of the underwater array light source, and also makes it convenient to disassemble and assemble the underwater array light source.

[0039] Reference Figure 2 and Figure 3A mounting groove 21 is provided at the middle position of the end of the water-facing side of the light source mounting base 2. The mounting groove 21 is arranged along the length direction of the light source mounting base 2 and is divided into six parts by six streamlined structural blocks 23. The single light source 1 includes a pressure-bearing cylinder 11, a lens group 12, an illumination source 13, and a drive assembly 14. The pressure-bearing cylinder 11 is sealed in the mounting groove 21. The lens group 12 is sealed in the end of the pressure-bearing cylinder 11 away from the bottom of the mounting groove 21. The lens group 12 includes a convex lens and a concave lens. The illumination source 13 is installed in the pressure-bearing cylinder 11 and is located in the pressure-bearing cylinder. The cylinder 11 is located near the end of the lens group 12. The drive assembly 14 includes a battery 141 and a motor 142. The battery 141 is fixedly connected to the inner wall of the pressure cylinder 11. The motor 142 is installed at the end of the battery 141 near the lighting source 13. The output shaft of the motor 142 is threadedly connected to the lamp bracket 143. The lamp bracket 143 is threadedly driven to the output shaft of the motor 142. The lamp bracket 143 is slidably connected to the inner wall of the pressure cylinder 11. The lighting source 13 is installed on the lamp bracket 143. Each individual light source 1 can independently adjust the brightness, chromaticity, and color temperature of the light source through the battery 141.

[0040] The individual light source 1 is installed in the mounting slot 21, and the individual light source 1 is protected and sealed by the light source mounting base 2, which reduces the damage to the individual light source 1 and helps to extend the service life of the individual light source 1. When it is necessary to adjust the emission angle of the light from the individual light source 1, the battery 141 supplies power to the motor 142, the motor 142 drives the lamp bracket 143 to slide in the pressure cylinder 11, the lamp bracket 143 drives the lighting source 13 to move, and adjusts the distance between the lighting source 13 and the lens group 12 to adjust the emission angle of the lighting source 13. It can realize multiple light output modes such as converging light, parallel light, and diverging light, and has a wider range of applications.

[0041] Reference Figure 2 and Figure 3 The bottom of the mounting groove 21 is provided with a wiring groove 22. One end face of the pressure-bearing cylinder 11 near the bottom of the mounting groove 21 is connected to the mounting groove 21. The wiring groove 22 is connected to the pressure-bearing cylinder 11. The reinforcing rod 4 is provided with a wiring groove 41. Both ends of the wiring groove 41 are connected to the wiring groove 22. Both the wiring groove 22 and the wiring groove 41 are provided with wires. The wires extend into the pressure-bearing cylinder 11. When assembling the underwater array light source, the wires are inserted into the wiring groove 22 and the wiring groove 41 in sequence and electrically connected to the circuit board on the battery 141. The circuit of the entire underwater array light source is controlled by the wires.

[0042] Reference Figure 2The lens at the end of the single light source 1 furthest from the bottom of the mounting groove 21 protrudes outward in an arc shape. The end of the light source mounting base 2 on the water-facing side is round, and the end of the light source mounting base 2 on the back side is pointed. The overall structure of the light source mounting base 2 is streamlined. The back side of the connecting bridge 3 is recessed towards the water-facing side to form an arched bridge opening.

The two ends of the biomimetic arched truss structure formed by the reinforcing rod 4 and the connecting bridge 3 are integrally formed.

[0043] When the underwater array light source moves underwater, the streamlined shape of the light source mounting base 2 and the streamlined shape of the connecting bridge 3 on the water-facing side reduces the resistance of the underwater array light source. The connecting bridge 3 has a biomimetic arched truss structure, which, with the cooperation of the reinforcing rod 4, enhances the structural strength between the light source mounting bases 2, which is beneficial to improving the overall structural strength and stability of the underwater array light source. Moreover, the biomimetic arched truss structure experiences less resistance from the water flow and has the characteristic of parallelizing the water flow, which can parallelize turbulent water flow and make the underwater robot connected to the underwater array light source more stable in posture.

Individual light sources 1 are installed within the light source mounting bases 2 to form an array light source, enabling wide-area illumination and ensuring sufficient underwater light to meet long-distance lighting and imaging requirements. Simultaneously, the honeycomb-shaped equilateral hexagonal structure formed by the individual light sources 1 and connecting bridges 3 pushes the light source array underwater. This honeycomb-shaped equilateral hexagonal structure greatly reduces the resistance of water flow to the underwater array light source. Connecting bridge 3 is a biomimetic arched truss structure, which has the characteristic of parallelizing water flow, thus balancing turbulent water flow and stabilizing the posture of the underwater robot connected to the underwater array light source. Multiple individual light sources 1, combined through the biomimetic honeycomb-shaped equilateral hexagonal truss structure, can achieve effective illumination surfaces at different underwater distances and different illumination effects under the effect of light focusing at different focal points.
