Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a stage light head housing structure. Background Technology

[0002] The lamp head 101 of a stage light typically includes a heat sink module 10 and a housing 20 on top of the heat sink module 10; the housing 20 contains a light-emitting unit; the connection between the housing 20 and the heat sink module 10 requires the cooperation of a boss 12 / second boss 21 structure to complete the fixed connection between the two; such as Figure 1 As shown, the heat sink module 10 includes two opposing side plates 11; the top of the side plates 11 is provided with an outwardly extending boss 12 / second boss 21; the interior of the outer casing 20 is provided with an inwardly extending second boss 21, and a sealing ring 30 is provided between the boss 12 / second boss 21 and the second boss 21. The side plates 11 and the outer casing 20 are connected and sealed by screws 40; in another structure, the second boss 21 can also protrude outward 130; in another structure, when the heat sink module 10 does not have side plates 11 and the outer casing 20 is directly installed on the top of the heat sink module 10, the second boss 21 needs to be provided on the outside. The outer side of the shell 20; the principle of the above structure is to form a wider platform for the connection between the two, and the boss 12 / second boss 21 needs to extend outward to facilitate the installation of the screw 40. This results in the expansion of the size of the lamp product and the irregular protrusion 130 on the outer contour, which affects the aesthetics and increases the cost. Since the thickness of the shell 20 would exceed the standard if it were set to accommodate the size of the conventional screw 40, it would not only increase the cost but also increase the weight of the lamp. Therefore, there is an urgent need for a structure that can eliminate the boss 12 / second boss 21 structure and effectively achieve a stable connection between the shell 20 and the heat sink module 10. Utility Model Content

[0003] In order to solve the above-mentioned problems of the prior art, the present invention provides a stage light head housing structure.

[0004] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0005] A stage light head housing structure includes a heat dissipation assembly; a lamp housing is connected to the heat dissipation assembly; a connecting plate extending along a first direction and connected to the heat dissipation assembly is provided on the lamp housing; a sealing ring receiving groove is provided on the lamp housing; a sealing ring is provided in the sealing ring receiving groove; the dimension of the sealing ring receiving groove in the first direction is smaller than the dimension of the sealing ring in the first direction; the sealing ring abuts against the heat dissipation assembly along the first direction; a plurality of mounting holes are provided at intervals on the connecting plate; the central axis of the mounting holes is arranged at an angle to the first direction; a mating hole is provided on the heat dissipation assembly to mate with the mounting holes; the connecting plate uses a fixing screw passing through the mounting hole to press the sealing ring against the mating hole.

[0006] Furthermore, the heat dissipation assembly includes two first side plates arranged opposite to each other; the connecting plate is connected to the first side plates; and the mating hole is provided on the first side plates.

[0007] Furthermore, the inner side of the first side plate is provided with a protrusion arranged along the length direction of the first side plate; the mating hole is located inside the protrusion.

[0008] Furthermore, two protrusions are arranged in parallel; each protrusion has a mating hole spaced apart; the connecting plate has a first mounting hole and a second mounting hole that respectively mate with the mating holes on the two protrusions.

[0009] Furthermore, the thickness of the connecting plate is less than the thickness of the lamp housing; the sealing ring is an O-ring.

[0010] Furthermore, the lamp housing is provided with a hollowed-out portion along its length.

[0011] The beneficial effects of this utility model are as follows: the fixing direction of the heat dissipation component and the lamp housing is changed from the original vertical direction to the horizontal direction, or a direction with a small angle to the horizontal direction, thereby eliminating the need for a boss structure for installing fixing screws. The fixing screws are accommodated by the heat dissipation component, and the connection and sealing between the heat dissipation component and the lamp housing utilizes the interference fit between the fixing screw and the mating hole to compress the sealing ring, rather than relying on the pressure of the screw tightening directly acting on the sealing ring as in the traditional structure. In other words, the purpose of designing a boss in the traditional structure is to provide sufficient pressure to compress the sealing ring when the screw is fixed, requiring the cooperation of the boss structure in the direction of the screw's force application. In this application, however, the threaded rod structure of the fixing screw applies pressure to the sealing ring through an interference fit, thus eliminating the need for a boss structure. This reduces material usage and lowers raw material costs, simplifies the production process, improves production efficiency, and indirectly reduces production costs. The absence of a boss structure and the optimized design of the shell thickness reduce the overall weight of the lamp, greatly improving the flexibility of the stage light during installation, transportation, and use.

[0023] For an example, please refer to... Figure 2-5 As shown:

[0024] A stage light head housing structure includes a heat dissipation assembly 100; a lamp housing 200 is connected to the heat dissipation assembly 100; a connecting plate 210 extending along a first direction and connected to the heat dissipation assembly 100 is provided on the lamp housing 200; a sealing ring receiving groove 220 is provided on the lamp housing 200; a sealing ring 30 is provided in the sealing ring receiving groove 220; the dimension of the sealing ring receiving groove 220 in the first direction is smaller than the dimension of the sealing ring 30 in the first direction; the sealing ring 30 abuts against the heat dissipation assembly 100 along the first direction; a plurality of mounting holes 211 are provided at intervals on the connecting plate 210; the central axis direction of the mounting holes 211 is arranged at an angle to the first direction; the heat dissipation assembly 100 is provided with mating holes 111 that mate with the mounting holes 211; the connecting plate 210 uses a fixing screw 120 passing through the mounting holes 211 to press the sealing ring 30 by interference fit with the mating holes 111.

[0025] Existing technology relies on the connection of boss 12 / second boss 21, resulting in an enlarged lamp size and irregular protrusions 130 on the outer contour. This structure eliminates the need for boss 12 / second boss 21. By setting a connecting plate 210 extending along the first direction and connecting it to the heat dissipation assembly 100, the problem of increased lamp size and unsightly appearance caused by the outward extension of boss 12 / second boss 21 is avoided, making the lamp more compact and aesthetically pleasing overall. The fixing direction of the heat dissipation assembly 100 and the lamp housing 200 is changed from the original vertical direction to the horizontal direction, or a direction with a small angle to the horizontal direction, thus eliminating the need for the boss 12 / second boss 21 structure for mounting screw 40. The fixing screw 120 is accommodated by the heat dissipation assembly 100. The connection and sealing between the heat dissipation assembly 100 and the lamp housing 200 utilizes the interference fit between the fixing screw 120 and the mating hole 111 to compress the sealing ring 30, rather than using the pressure of the screw 40 when tightening to directly act on the sealing ring 30 as in the traditional structure; it can also be understood that the traditional structure uses... The purpose of the boss 12 / second boss 21 is to provide sufficient pressure to compress the sealing ring 30 when the screw 40 is fixed, requiring the engagement of the boss 12 / second boss 21 structure from the direction of force applied by the screw 40. However, in this application, the threaded rod of the fixing screw 120 is used to apply pressure to the sealing ring 30 through an interference fit, thus eliminating the need for the boss 12 / second boss 21 structure. This reduces material usage and lowers raw material costs, while also simplifying the manufacturing process, improving production efficiency, and indirectly reducing production costs. The elimination of the boss 12 / second boss 21 structure and the optimized design of the outer shell 20 reduce the overall weight of the lamp, significantly improving the flexibility of installation, transportation, and use of the stage lamp.

[0026] The lamp housing 200 is provided with a sealing ring receiving groove 220, and the dimension of the sealing ring receiving groove 220 in the first direction is smaller than the dimension of the sealing ring 30 in the first direction. When the connecting plate 210 is pressurized with the mating hole 111 of the heat dissipation component 100 using the fixing screw 120, the sealing ring 30 will be squeezed, so that the sealing ring 30 is tightly abutted against the heat dissipation component 100 along the first direction, thereby forming a good sealing effect, effectively preventing dust, moisture and other substances from entering the lamp head 101, protecting the light-emitting unit and other components, and extending the service life of the lamp. The connecting plate 210 is provided with several mounting holes 211 at intervals, and the central axis of the mounting holes 211 is arranged at an angle to the first direction. The fixing screw 120 passing through the mounting hole 211 is pressurized with the mating hole 111 on the heat dissipation component 100. Compared with the traditional boss 12 / second boss 21 plus screw 40 connection method, this design can provide a more stable connection force, ensuring that the lamp housing 200 and the heat dissipation component 100 will not easily loosen during use, ensuring the normal operation of the stage lamp. In traditional connection structures, screw 40 can only provide vertical force to lamp housing 200. However, in this structure, the shank of fixing screw 120 is used to provide vertical force, and it can also provide lateral force when threaded, which can further increase the connection stability between lamp housing 200 and heat dissipation component 100.

[0027] In one embodiment, the heat dissipation assembly 100 includes two opposing first side plates 110; the connecting plate 210 is connected to the first side plates 110; and the mating hole 111 is provided on the first side plates 110. The opposing first side plates 110 can support and connect the lamp housing 200 from both sides, making the structure of the entire lamp head 101 more stable and symmetrical. This also increases the usable space inside the lamp head 101. This structure is commonly used in long, narrow lamps. In circular stage lamp structures, the first side plates 110 are generally not provided; in this case, the connecting plate 210 can be directly connected to the side of the heat dissipation assembly 100.

[0028] In one embodiment, a protrusion 130 is provided on the inner side of the first side plate 110 along the length of the first side plate 110; the mating hole 111 is located within the protrusion 130. The protrusion 130 is equivalent to adding a reinforcing rib structure to the inner side of the first side plate 110. It can effectively improve the structural strength of the first side plate 110, making it less prone to deformation when subjected to the forces from the lamp housing 200 and the fixing screw 120. Especially when the stage light may be subjected to external forces such as vibration and collision during use, this protrusion 130 structure can better maintain the shape and stability of the first side plate 110, thereby ensuring the stability of the entire lamp head 101 structure and reducing problems such as loosening of connections caused by deformation of the side plate 11. Setting the mating hole 111 within the protrusion 130 allows for more precise positioning of the mating hole 111. When installing the fixing screw 120, since the protrusion 130 plays a certain limiting and guiding role on the mating hole 111, the fixing screw 120 is more easily and accurately inserted into the mating hole 111, improving the installation accuracy and success rate. The protrusion 130 increases the surface area of ​​the first side plate 110, further expanding the contact area between the heat dissipation component 100 and the air. This means that during heat dissipation, heat can be transferred to the air over a larger area, optimizing the heat dissipation path. The protrusion 130 is located on the inner side, so it does not significantly increase the product size of the lamp holder 101. Furthermore, the size of the protrusion 130 is related to the length of the fixing screw 120, allowing for reasonable adjustment based on requirements, ensuring both cost-effectiveness and fixing strength.

[0029] In one embodiment, two protrusions 130 are arranged in parallel; each protrusion 130 has a spaced-apart mating hole 111; the connecting plate 210 has a first mounting hole 212 and a second mounting hole 213 that respectively mate with the mating holes 111 on the two protrusions 130. Compared to a single protrusion 130, the two parallel protrusions 130 provide stronger support and reinforcement for the first side plate 110. When subjected to various forces such as the weight of the lamp housing 200 and the tensile force generated when the fixing screws 120 are tightened, the stress can be more effectively dispersed, greatly reducing the possibility of deformation of the first side plate 110. Even when the stage lamp encounters extreme situations such as severe vibration or accidental collision, the integrity of the overall structure can be better maintained, ensuring the stable connection of each component of the lamp head 101, reducing failures caused by structural instability, and extending the service life of the stage lamp. The spaced-apart mating holes 111 and the corresponding first mounting holes 212 and second mounting holes 213 make the connection points between the lamp housing 200 and the heat dissipation assembly 100 more evenly distributed. When using the fixing screws 120 for connection, the multiple connection points work together to more evenly fix the lamp housing 200 to the heat dissipation component 100, avoiding situations where the force is too great or too small in some areas due to uneven distribution of connection points. This not only enhances the reliability of the connection, but also ensures a more stable sealing effect between the lamp housing 200 and the heat dissipation component 100, preventing dust, moisture and other impurities from entering the lamp and protecting the core components of the lamp.

[0030] In one embodiment, the thickness of the connecting plate 210 is less than the thickness of the lamp housing 200; the sealing ring 30 is an O-ring. Designing the thickness of the connecting plate 210 to be less than the thickness of the lamp housing 200 allows for a reasonable allocation of materials while ensuring the strength of the connection structure. Since the connecting plate 210 primarily connects the lamp housing 200 to the heat dissipation assembly 100, it does not require materials of the same thickness as the lamp housing 200 to guarantee its function. This design reduces material usage, thereby lowering production costs and reducing the overall weight of the lamp, making installation and use more convenient. The thinner connecting plate 210 better adapts to the connection points on the heat dissipation assembly 100, especially in the connection design with the first side plate 110, resulting in a more compact overall structure. Excessive thickness of the connecting plate 210 will not occupy too much space, affecting the layout and installation of other internal components of the lamp, which is beneficial for achieving miniaturized lamp design and meeting the size requirements of stage lights in different scenarios. The thinness of the connecting plate 210 facilitates the installation of the fixing screw 120 when it is interference-fitted, and allows the fixing screw 120 to be tilted at a certain angle after passing through the mounting hole 211, so as to mate with the mating hole 111.

[0031] In one embodiment, the lamp housing 200 has a hollow portion 230 along its length. The hollow portion 230 reduces the amount of material used in the lamp housing 200, and significantly reduces the overall weight of the lamp without affecting the basic structural strength and function of the lamp housing 200.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
