Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and in particular to a light-collecting housing for stage lights. Background Technology

[0002] Stage lights are an important component of stage lighting equipment. They provide crucial lighting effects for stage performances. Their main function is to illuminate the stage while creating specific atmospheres and visual effects. Stage lights can highlight the actors' performances, guide the audience's gaze, and enhance the artistic expression of the stage. The lamp housing is a key component of the stage light. It not only prevents the bulb from being damaged by collisions or external factors, but also allows for the adjustment of the light diffusion and projection angle through its design to achieve specific lighting effects.

[0003] An investigation revealed that Chinese utility model patent CN205424814U discloses an LED stage light with multiple light-emitting colors. The LED stage light includes a lamp head, a lamp arm, and a base connected sequentially from top to bottom. The lamp head contains a lens module for light collection, refraction, and color mixing, and an LED light source module with multiple light-emitting colors. The lamp arm contains a Y-axis rotation mechanism for controlling the rotation of the lamp head in the Y-axis direction. The base contains an X-axis rotation mechanism for controlling the rotation of the lamp arm in the X-axis direction. This LED stage light can project light of multiple colors and arbitrary brightness as needed, and the projection angle can be controlled, effectively enhancing the atmosphere of the application environment.

[0004] However, stage lights are often installed at high places. In some theaters and fixed performance venues, stage lights are fixed to the ceiling of the performance hall for a long time, which makes disassembly and cleaning very inconvenient. In order to ensure normal use, stage lights often have heat dissipation vents on the lamp housing, and heat is dissipated through fixed heat dissipation plates. However, open heat dissipation vents can cause dust to fall into the lamp body. Even with filters, dust cannot be effectively intercepted, and the filters can become clogged, resulting in poor heat dissipation efficiency. Moreover, the usage time of stage lights is often shorter than the time they are turned off, and the time that the cooling fan works is not enough to provide good protection. Therefore, the above-mentioned LED stage lights cannot effectively prevent dust from falling into the lamp body, resulting in increased cleaning frequency, inconvenient operation, and high maintenance costs.

[0005] Therefore, it is necessary to design a light-collecting housing for stage lights to solve the above problems. Utility Model Content

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting a servo motor to drive the gear, gear ring and rotating shaft, the heat sink can be rotated to a position perpendicular to the main housing when the equipment is working, maximizing the heat dissipation area, effectively dissipating the heat generated during the operation of the equipment, and extending the service life of the equipment. After the performance, the servo motor reverses, the heat sink automatically resets and overlaps to close the heat dissipation vents, effectively preventing dust from entering the stage light through the heat dissipation vents during idle periods.

A heat dissipation vent 4 is provided on the main housing 2. Two mounting slots 41 are symmetrically provided on the main housing 2 at the position of the heat dissipation vent 4. Several rotating shafts 42 are uniformly rotatably mounted in the mounting slots 41. A heat dissipation plate 43 adapted to the heat dissipation vent 4 is fitted on the rotating shafts 42. A drive mechanism is provided in the mounting slots 41.

[0027] The drive mechanism includes a servo motor 5 fixedly mounted on the bottom wall of the main housing 2 away from the sub-housing 3, and a gear 51 fixedly mounted on the output end of the servo motor 5. A gear ring 52 is rotatably mounted in the mounting groove 41 away from the sub-housing 3. The inner side wall of the gear ring 52 extending into the main housing 2 is provided with internal teeth that mesh with the gear 51, and the outer side wall of the gear ring 52 extending into the mounting groove 41 is provided with external teeth. Several gears 53 corresponding to the rotating shaft 42 are rotatably mounted in the mounting groove 41, and the gears 53 mesh with the external teeth. A vibration mechanism is provided between the rotating shaft 42 and the gears 53. When the stage lights are in use, the heat sink 43 can be rotated to a position perpendicular to the main housing 2, maximizing the area of ​​the heat dissipation vent 4, effectively dissipating the heat generated during equipment operation, and extending the service life of the equipment. Through the linkage of the gear ring 52, all heat sinks 43 can be synchronously adjusted, thereby adjusting the opening area of ​​the heat dissipation vent 4, making the equipment operation more stable.

[0028] Reference Figures 2 to 5The vibration mechanism includes a guide cylinder 6 fixedly mounted on gear 53, a groove fixedly mounted inside the guide cylinder 6, and a fixed cylinder 63 fixedly mounted inside another mounting slot 41. A rotating shaft 42 is rotatably mounted inside the fixed cylinder 63. A guide block 61 adapted to the groove is fixedly mounted on the rotating shaft 42. Both the guide cylinder 6 and the fixed cylinder 63 are slidably connected to the rotating shaft 42. A ring of protrusions arranged in a circular array is fixedly mounted on one end of the fixed cylinder 6 near the guide cylinder 6. A wave ring 64 adapted to the protrusions is fixedly fitted on the rotating shaft 42. A spring 62 is fixedly mounted between the guide cylinder 6 and the rotating shaft 42. This causes the heat sink 43 to vibrate while rotating, effectively shaking off dust from the heat sink 43 and the housing, preventing dust from being brought into the equipment, and further improving the protective effect of the equipment.

[0029] Reference Figure 2 and Figure 3 The height of the heat sink 43 is less than the height of the heat sink 4, and the end of the heat sink 43 away from the base 1 is coplanar with the heat sink 4. A sealing plate 65 is fixedly installed on the bottom wall of the heat sink 4 near the axis of the main housing 2, and the sum of the heights of the sealing plate 65 and the heat sink 43 is greater than the height of the heat sink 4. The sealing plate 65 can cooperate with the heat sink 43 to seal the heat sink 4 and optimize the dustproof effect.

[0030] Reference Figure 2 A groove 7 is provided on the end of the main housing 2 away from the base 1, and the sub-housing 3 is slidably connected to the groove 7; so that the sub-housing 3 can slide smoothly in the groove 7 of the main housing 2, and the distance between the light and the lens can be precisely adjusted to meet the lighting and light collection needs in different scenarios.

[0031] Reference Figure 2 and Figure 6 A fixing plate 71 is fixedly installed on the inner wall of the main housing 2. A servo motor 72 is fixedly installed on the fixing plate 71. A connecting rod 73 is fixedly installed at the output end of the servo motor 72. A worm gear 74 is fixedly installed at the other end of the connecting rod 73. A guide groove 75 is opened on the main housing 2 corresponding to the position of the worm gear 74. A rack 76 that meshes with the worm gear 74 is slidably installed in the guide groove 75. The rack 76 is fixedly connected to the secondary housing 3. The cooperative design of the worm gear 74 and the rack 76 ensures the self-locking of the movement of the secondary housing 3, realizes stepless extension and precise positioning, improves the safety and practicality of use, and ensures the stability and accuracy of the stage lights during performance.

[0032] The specific working principle of this utility model is as follows:

[0033] When in use, the stage lights are turned on, and then the servo motor 5 is started. When the servo motor 5 rotates, it drives the gear 51 to rotate, which in turn drives the meshing gear ring 52 to rotate. The gear ring 52 drives the gear 53 to rotate, which in turn drives the rotating shaft 42 to rotate. This causes the heat sink 43 to rotate in a direction perpendicular to the main housing 2, fully opening the heat dissipation vent 4. This helps to dissipate heat during use and protects the lifespan of the equipment. After the stage performance ends, the stage lights are turned off, and the servo motor 5 reverses, causing the heat sink 43 to rotate and reset. The heat sinks 43 overlap each other, closing the heat dissipation vent 4. This prevents dust from falling into the stage lights through the heat dissipation vent 4 during idle time, effectively ensuring the cleanliness of the stage lights, reducing the frequency of cleaning, reducing the tedious operation of frequent manual disassembly and assembly, saving manpower and cleaning costs, and extending the lifespan of the equipment.

[0034] When gear 53 rotates, it drives guide cylinder 6 to rotate. At the same time, due to the action of guide block 61, rotating shaft 42 can rotate with guide cylinder 6. During rotation, it drives the wave ring 64 fixedly connected to it to rotate. Since fixed cylinder 63 and protrusion are fixedly set, when wave ring 64 rotates, it will drive rotating shaft 42 to slide along guide cylinder 6 under the action of protrusion. At the same time, under the action of spring 62, it will repeatedly slide and reset, causing heat sink 43 to vibrate. This can shake off the dust on heat sink 43 and housing while rotating, preventing dust from being brought into the equipment by heat sink 43, thus better protecting the stage lights. Sealing plate 65 can cooperate with heat sink 43 to seal heat dissipation port 4 and improve dust prevention effect.

[0035] The rotation of servo motor 72 drives worm gear 74 to rotate, and worm gear 74 drives rack 76 that meshes with it, so that the secondary housing 3 slides within the groove 7 on the main housing 2 to adjust the distance, thereby adjusting the distance between the light and the lens. Worm gear 74 and rack 76 can make the movement of secondary housing 3 self-locking, which can ensure the stepless extension and precise positioning of secondary housing 3, and improve the safety and practicality of use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
