Description

Technical Field

[0001] The present invention relates to the technical field of lighting equipment, and in particular to a high-heat dissipation hanging type stadium lamp which is convenient for adjusting the irradiation angle. Background Art

[0002] Stadium lights are a type of high-power lamp commonly used in stadiums. Stadium lights are generally installed at higher locations, so they have a larger lighting coverage area, thus being able to meet the lighting needs of large venues.

[0003] Although stadium lights can provide a large area of ​​lighting, they also have some defects, such as glare. The glare problem of stadium lights is that the light emitted from the light source cannot be concentrated and illuminated to one place, and there is too high brightness in a certain part of the field of vision or too much brightness change before and after. To solve this problem, people set a sunshade on the stadium lights to reflect the light to solve the glare problem.

[0004] However, since different scenes have different requirements for the lighting of the stadium lights, the lighting effects of the stadium lights will also be different. The means to change the lighting effect can be achieved by adjusting the light direction of the lamp and adjusting the reflection angle of the sunshade;

[0005] Generally, a sunshade is arranged on the outside of the light source module of the lamp, and its semi-enclosed structure is used to refract the light emitted by the light source module. At present, the sunshades of the stadium are all separate and need to be added later. The actual sunshade is relatively large in size, which leads to the large size of the stadium lamp and inconvenience in installation. In order to minimize the size of the sunshade, the sunshade and the stadium lamp are formed into one piece, which can reduce the size of the stadium lamp. However, when the sunshade and the stadium lamp are formed into one piece, the illumination effect of the light can only be changed by adjusting the light output direction of the lamp. When adjusting the angle of the existing angle adjustment structure, the hinged structure with a smaller angle is prone to slipping and falling under the weight of the stadium lamp after the locking mechanism is released, which imposes a momentary high load on the bracket, affecting the life of the bracket and easily causing it to fall.

[0006] High-power stadium lights are heavy and large in size. As the power increases, the heat dissipation requirements become higher and the power load becomes greater. Often, due to the problem of power heat dissipation, the life of the lamp will not meet the expected requirements, which is not conducive to increasing the practicality of the stadium lights. Summary of the invention

[0007] In view of the technical defects existing in the background technology, the present invention proposes a high heat dissipation hanging type stadium lamp which is easy to adjust the illumination angle, solves the above technical problems and meets the actual needs.

[0012] As an improvement of the above solution, the hinge structure includes a first cover body, a second cover body, a rotating member and a locking member;

[0013] The first cover is disposed at an end of the first support rod in a direction facing the second support rod, and the second cover is disposed at an end of the second support rod in a direction close to the first support rod.

[0014] As an improvement of the above solution, the outer edge of the first cover body is buckled with the outer edge of the second cover body, the locking member is arranged in the first cover body, and the rotating member is arranged in the second cover body.

[0015] As an improvement of the above solution, the inner wall of the second cover body is provided with a second fixing groove for clamping the outer edge of the rotating member, and the second cover body has a side surface 1 that is hemispherically convex toward the outside, and the inner wall of the side surface 1 is provided with clamping grooves distributed in an annular manner;

[0016] The inner wall of the first cover body is provided with a fixing groove 1 for clamping the outer edge of the locking member, the side of the rotating member facing the side 1 is provided with a hemispherical side 2, the outer surface of the side 2 is provided with spherical protrusions distributed in a ring shape, and the number and shape of the spherical protrusions are adapted to the clamping grooves.

[0017] As an improvement of the above solution, a square clamp is provided on the side where the rotating member and the locking member fit together, and the end face of the locking member facing the rotating member is provided with a square groove adapted to the square clamp, and spherical cylinders distributed in a ring shape around the square groove.

[0018] As an improvement on the above scheme, a tightening screw is passed through the horizontal direction of the first cover body, the second cover body, the locking member and the rotating member, and the locking member reciprocates along the length direction of the tightening screw. When the tightening screw is screwed toward the second cover body to the maximum stroke, the locking member contacts and fits with the rotating member, and the spherical cylinder contacts and fits with the back side of the spherical protrusion.

[0019] As an improvement of the above solution, the lamp body includes a shell and a first side plate and a second side plate arranged on both sides of the shell in the longitudinal direction, the first side plate and the second side plate form a first heat dissipation groove and a second heat dissipation groove for accommodating the heat dissipation assembly at the back of the shell, and the first side plate and the second side plate form a first light groove and a second light groove for accommodating the light source assembly at the front of the shell;

[0020] As an improvement of the above scheme, the heat dissipation component is arranged in the heat dissipation slot, and the heat dissipation component includes fins and heat pipes passing through the fins. The heat pipes and fins are connected and fixed by solder paste, and the fins are fixed in the heat dissipation slot by aluminum paste welding.

[0023] The beneficial effects of the present invention are:

[0024] 1. The illumination angle of the lamp body is adjusted by adjusting the hinge structure between the first support rod and the second support rod. When the tightening screw is loosened, the friction between the spherical protrusion on the rotating part and the clamping groove in the second cover body forms a rotation resistance, which plays a blocking role and prevents the lamp body from suddenly slipping and falling, thereby having high safety.

[0025] 2. After loosening the tightening screw, manually unfold the first support rod and the second support rod, and the fastener drives the rotating part to rotate. The spherical protrusions on the rotating part are squeezed and deformed during rotation and then shrink. As the fastener rotates, they reset and pop out one by one in the adjacent clamping grooves, preventing the main body of the lamp from slipping and falling.

[0026] 3. The shell and the first side panel and the second side panel are die-cast to form a light trough opening downward and a heat dissipation trough opening upward. By combining the die-casting with the fins and the heat pipe, the heat dissipation effect is improved while reducing the overall structural weight of the lamp body, which is convenient for installation.

[0027] 4. The shading hood is formed integrally with the shell, and plays an anti-glare role and has a small size. Compared with traditional lamps with shading hoods, the small structure means it is lighter, occupies a small installation area, and is more convenient to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] It should be noted that the hot air generated by the lamp body 1 when in use flows upward, and the shell 101 is provided with a heat dissipation hole 54 at the connection position corresponding to the first light slot 41 and the second light slot 42, through which the heat generated by the light source assembly 6 is channeled, thereby enhancing the heat dissipation effect of the heat dissipation assembly 8.

[0048] In the mounting structure of the lamp body 1 of the present invention, the lamp body 1 is fixed to the mounting bracket by a longitudinal adjustment mechanism 3, a mounting base 2 is provided between the top of the first support rod 31 and the mounting bracket, the mounting base 2 is fixed to the mounting bracket by screws, the top of the first support rod 31 is screwed and fixed to the mounting base 2 by screws, and the bottom of the second support rod 32 is screwed and fixed to the fixed base of the lamp body 1 by screws;

[0050] In the technical solution of the hinge structure of the present invention, the hinge structure includes a first cover body 311, a second cover body 321, a rotating member 33 and a locking member 34;

[0051] According to the principle of the hinge structure of the present invention, a first cover body 311 is provided at the end of the first support rod 31, and a second cover body 321 is provided at the end of the second support rod 32. A locking member 34 is provided in the first cover body 311, and a rotating member 33 is provided in the second cover body 321. The locking member 34 drives the rotating member 33 to rotate synchronously. A loosening screw 35 for driving the loosening member to move axially is provided along the direction from the first cover body 311 to the second cover body 321. A blocking structure for limiting the rotation speed between the first support rod 31 and the second support rod 32 is provided between the inner surface of the rotating member 33 and the second cover body 321. When the loosening screw 35 drives the locking member 34 to move toward the rotating member 33 to the maximum working process, the rotating member 33 is abutted and locked to achieve the purpose of locking the hinge structure.

[0052] Further, in the above scheme, the first cover body 311 is arranged at the end of the first support rod 31 in the direction toward the second support rod 32, the second cover body 321 is arranged at the end of the second support rod 32 close to the first support rod 31, the rotating member 33 and the locking member 34 are arranged between the first cover body 311 and the second cover body 321 in the buckled state, specifically, the outer edge of the first cover body 311 is buckled with the outer edge of the second cover body 321, the locking member 34 is arranged in the first cover body 311, and the rotating member 33 is arranged in the second cover body 321;

[0053] In the technical solution of the blocking structure of the present invention, the inner wall of the second cover body 321 is provided with a second fixing groove 322 for clamping the outer edge of the rotating member 33. The rotating member 33 is a cylinder with a spherical surface at one end. The outer surface of the rotating member 33 is clamped with the first fixing groove 312 to limit the axial movement of the rotating member 33 but not the circumferential rotation of the rotating member 33.

[0054] Furthermore, the second cover body 321 has a side surface 323 that is hemispherically protruding outward, and the inner wall of the side surface 323 is provided with a ring-shaped snap-in groove 324, and the side of the rotating member 33 that faces the side surface 323 is provided with a hemispherical side surface 331, and the outer surface of the side surface 331 is provided with spherical protrusions 332 that are distributed in a ring shape, and the number and shape of the spherical protrusions 332 are adapted to the snap-in grooves 324.

[0055] It should be noted that the rotating member 33 is clamped in the fixing groove 1 312, and one end of the rotating member 33 having a spherical surface is in contact with the inner wall of the second cover body 321, that is, the outer surface of the side 2 331 is in contact with the inner surface of the side 1 323, and a spherical protrusion 332 is provided at the position of the rotating member 33 corresponding to the side 2 331, and a clamping groove 324 matching the spherical protrusion 332 is provided at the bottom of the second cover body 321. When the side 1 323 and the side 2 331 are in contact, the spherical protrusion 332 and the clamping groove 324 play a blocking role in the hinge structure to prevent the lamp body 1 from suddenly slipping and falling, thereby having high safety.

[0056] It should be noted that the rotating member 33 is a plastic member with certain structural strength and elastic deformation performance. The rotating member 33 reserves a space sufficient for the spherical protrusion 332 to be compressed by force at the back of the spherical protrusion 332, so that the rotating member 33 and the second cover body 321 are in an incompletely stuck state. When the second support rod 32 rotates, it needs to exert a force sufficient to compress the spherical protrusion 332 to achieve rotation.

[0057] In the technical solution of the locking member 34 of the present invention, the locking member 34 plays the role of locking the spherical protrusion 332 and driving the rotating member 33 to rotate synchronously in the hinge structure;

[0058] Specifically, the inner wall of the first cover body 311 is provided with a fixing groove 312 for clamping the outer edge of the locking member 34, and the difference between the first cover body 311 and the connection structure between the second cover body 321 and the rotating member 33 is that the fixing groove 312 limits the circumferential rotation of the locking member 34, but does not limit the axial movement of the locking member 34, the first support rod 31 drives the locking member 34 to rotate circumferentially, and the loosening screw 35 drives the locking member 34 to move axially;

[0059] Further, in the above scheme, a square clamp 333 is provided on the side where the rotating member 33 and the locking member 34 are in contact, and a square groove 341 adapted to the square clamp 333 is provided on the end surface of the locking member 34 facing the rotating member 33, and the square clamp 333 is inserted into the square groove 341, so that when the first support rod 31 drives the locking member 34 to rotate circumferentially, the elastic member drives the rotating member 33 to rotate;

[0060] Furthermore, in the above solution, the side of the locking member 34 facing the rotating member 33 has a spherical cylinder 342 distributed in an annular manner around the square groove 341, and the shape of the end of the spherical cylinder 342 matches the shape of the spherical protrusion 332 on the rotating member 33;

[0061] Specifically, a tightening screw 35 is penetrated in the horizontal direction of the first cover body 311, the second cover body 321, the locking member 34 and the rotating member 33, and the locking member 34 reciprocates along the length direction of the tightening screw 35. When the tightening screw 35 is screwed to the maximum direction toward the second cover body 321, the locking member 34 and the rotating member 33 are in contact with each other, and the spherical cylinder 342 and the back side of the spherical protrusion 332 are in contact with each other. After the spherical cylinder 342 and the back side of the spherical protrusion 332 are in contact with each other, the rotating member 33 and the second cover body 321 are locked, and the spherical protrusion 332 cannot be deformed and contracted by force. The spherical protrusion 332 is fixed to the clamping groove 324, and the spherical protrusion 332 cannot be compressed by rotating the first support rod 31 or the second support rod 32, thereby achieving the locking of the first support rod 31 and the second support rod 32.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
