Description

Technical Field

[0001] The utility model belongs to the field of stage lights, and particularly relates to a stage light capable of quickly installing, replacing and adjusting a bulb. Background Art

[0002] In modern stage performances, the design and application of lighting equipment are crucial for the success of the performance. However, the bulbs of stage lights are consumables, and after a period of use, there is a risk of bulb failure. To improve the maintenance efficiency of stage light bulbs, the installation structure of stage light bulbs in existing stage lights is usually designed to be quickly installable to improve the replacement efficiency of bulbs and avoid great inconvenience in replacing bulbs of stage lights hanging in the air or the falling of accessories. However, after replacing the bulb, it is necessary to re-adjust and calibrate the stage light, and most existing stage lights only consider the problem of quick installation, resulting in the inability to quickly adjust the bulbs of stage lights.

[0003] In the prior art, for example, the patent document with the publication number of CN207350266U discloses a device for quickly loading and unloading a bulb. The bulb can be quickly installed and disassembled by clamping the bulb in a way that the clamping block on the limiting plate is tightened by a tension spring. However, clamping the bulb by tightening the tension spring will cause the position of the bulb to be unable to be adjusted, and there is a risk of deviation in the lighting effect. Summary of the Invention

[0004] Aiming at the problems in the prior art, the utility model provides a stage light capable of quickly installing, replacing and adjusting a bulb. By pressing the edge of the bulb against the blocking unit, the blocking unit is pushed open to realize the quick installation and replacement of the stage light bulb. At the same time, the position of the light-emitting center of the bulb can be adjusted by rotating the eccentric shaft to quickly calibrate the replaced bulb, so that the replaced bulb can quickly achieve the best lighting effect.

[0005] The utility model is realized as follows: A stage light capable of quickly installing, replacing and adjusting a bulb includes a mounting plate. A bulb assembly and a heat dissipation assembly corresponding to the bulb assembly are provided on the mounting plate. The heat dissipation assembly includes at least one heat dissipation fan with a blowing port facing the bulb assembly.

[0006] The bulb assembly includes a bulb mount and a bulb. The bulb mount is slidably mounted on the mounting plate. The interior of the bulb mount is hollow to form a mounting hole for mounting the bulb. The inner wall of the mounting hole is provided with a plurality of blocking units, so the bulb mount is also provided with a spring clip adapted to the blocking unit. The blocking unit is partially exposed in the mounting hole under the pressure of the spring clip. When the bulb is inserted into the mounting hole, the bulb presses against the blocking unit and overcomes the elastic force of the spring clip, thereby pushing the blocking unit open to complete the installation. After the bulb is inserted into the mounting hole, the blocking unit is reset under the elastic force of the spring clip, contacts the outer surface of the bulb and generates resistance to prevent the installed bulb from loosening or falling off.

[0007] The bulb is provided with a rib adapted to the mounting hole. When the bulb is installed, the rib pushes away the blocking unit. After the bulb is installed, the blocking unit is reset under the pressure of the spring to fix the bulb and prevent it from falling out of the mounting hole. The outer layer of most existing bulbs is made of glass or other materials and is fragile. The rib is used to prevent the blocking unit from directly pressing the bulb and causing damage to the bulb, thereby improving the reliability of the bulb.

[0008] The bulb assembly also includes an eccentric shaft, which is in driving connection with the bulb mount and drives the bulb mount to reciprocate. By rotating the eccentric shaft, the user can easily adjust the position of the bulb mount without complicated steps. This not only improves adjustment efficiency but also reduces operational difficulty, making it easy for non-professionals to quickly learn how to use the device.

[0009] Preferably, the bulb assembly further includes a plurality of pre-tightening assemblies, one end of each of which passes through the bulb mount and is screwed onto the mounting plate; the other end of each of the pre-tightening assemblies presses against the bulb mount. The pre-tightening assemblies are used to apply a pre-tightening force to the bulb mount when adjusting the position of the bulb mount, thereby preventing the bulb mount from moving during adjustment and improving adjustment accuracy.

[0010] Specifically, the preload assembly includes an adjustment rod screwed to the mounting plate. An elastic unit is sleeved onto the adjustment rod. One end of the elastic unit elastically presses against the adjustment rod, and the other end is provided with a gasket. The elastic unit presses against the bulb mount via the gasket. Rotating the adjustment rod compresses or releases the elastic unit to adjust the preload force applied by the preload assembly to the bulb mount, thereby improving the compatibility and practicality of the preload assembly.

[0011] Preferably, the bulb includes a reflector cup, and the edge stop is arranged on the peripheral side of the reflector cup; the bulb mounting base further includes a blocking portion adapted to the edge stop, and an avoidance hole is formed between the blocking portions. The inner diameter of the reflector cup is smaller than the inner diameter of the avoidance hole. The blocking portion is used to prevent the bulb from falling out of the mounting hole, improving the reliability of the bulb installation. The inner diameter of the reflector cup being smaller than the inner diameter of the avoidance hole can prevent the blocking portion from blocking part of the light, enabling all the light reflected by the reflector cup to be utilized, thereby improving the lighting effect of the bulb.

[0012] Preferably, the upper peripheral side of the mounting hole increases from bottom to top to form a guiding portion. To prevent the bulb from shaking in the mounting hole, the radial dimension of the bulb is adapted to the inner diameter of the mounting hole. The guiding portion is used to guide the bulb when it enters the mounting hole, preventing the bulb from being difficult to align with the mounting hole and improving the convenience during the installation of the bulb.

[0013] Preferably, an avoidance groove penetrating the side wall of the mounting hole horizontally is further provided on the peripheral side of the mounting hole, and the bottom height of the avoidance groove is the same as the height of the edge stop after installation. The avoidance groove enables direct contact between the hand and the edge stop when installing the bulb, causing the force applied during bulb installation to act on the edge stop, avoiding the force directly acting on the bulb during bulb installation, and thereby reducing the risk of damage to the bulb during installation.

[0014] Preferably, a plurality of adjustment holes are further provided on the bulb mounting base, and the extending direction of the adjustment holes is the same as the adjustment direction of the bulb mounting base. The adjustment holes provide a margin for adjustment of the bulb mounting base and can also guide the adjustment of the bulb mounting base, improving the adjustment accuracy of the bulb mounting base.

[0015] Preferably, the blocking unit is a steel ball. As a metal product, the steel ball has extremely high strength and rigidity. When installing and removing the bulb, it can maintain its original shape and size, is not easily deformed, and improves the service life of the blocking unit. At the same time, the outer surface of the steel ball is an arc surface, which can provide a transition during the installation and removal of the bulb, improving the operational convenience during the installation and removal of the bulb.

[0016] Preferably, the heat dissipation component includes a first heat dissipation fan and a second heat dissipation fan arranged in parallel. The air outlets of the first heat dissipation fan and the air inlets of the second heat dissipation fan both face the back of the bulb, forming an effective back heat dissipation channel, significantly increasing the back heat dissipation area and accelerating the dissipation of heat from the back of the bulb. It also includes a third heat dissipation fan. A duct is provided at the air outlet of the third heat dissipation fan, and the air outlet of the duct faces the front of the bulb. The third heat dissipation fan takes into account the heat dissipation of the front of the bulb and can directly blow away the heat generated on the front of the bulb, avoiding the accumulation of heat on the front of the bulb.

[0017] Preferably, it further includes a heat insulation unit installed and fixed on the mounting plate. The heat insulation unit is arranged directly below the bulb, reducing the direct heat conduction of the heat generated by the bulb to the surrounding environment, and reducing the potential damage to sensitive components or materials existing below the bulb due to high temperature, thus improving the service life of the stage light.

[0018] Advantages of the present utility model:

[0019] The present utility model provides a stage light that can quickly install, replace and adjust the bulb. By pressing the edge of the bulb against the blocking unit to push the blocking unit open, the quick installation and replacement of the stage light bulb can be realized. At the same time, the position of the light-emitting center of the bulb can be adjusted by rotating the eccentric shaft, enabling users to easily adjust the position of the bulb mounting seat without complex operation steps. This not only improves the adjustment efficiency but also reduces the operation difficulty, allowing non-professional personnel to quickly get started and quickly calibrate the replaced bulb to quickly achieve the best lighting effect.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0027] As Figures 1 - 4 shown, a stage light that can quickly install, replace and adjust the bulb includes a mounting plate 1. A bulb assembly 2 and a heat dissipation assembly 3 corresponding to the bulb assembly 2 are provided on the mounting plate 1. The heat dissipation assembly 3 includes at least one heat dissipation fan with an air outlet facing the bulb assembly 2.

[0028] In this embodiment, the heat dissipation assembly 3 includes a first heat dissipation fan 31 and a second heat dissipation fan 32 arranged in parallel. The air outlet of the first heat dissipation fan 31 and the air inlet of the second heat dissipation fan 32 both face the back of the bulb 22, forming an effective back heat dissipation channel, significantly increasing the back heat dissipation area and accelerating the dissipation of the heat on the back of the bulb 22. It also includes a third heat dissipation fan 33. A duct is provided at the air outlet of the third heat dissipation fan 33, and the air outlet of the duct faces the front of the bulb 22. The third heat dissipation fan 33 takes into account the heat dissipation on the front of the bulb 22 and can directly blow away the heat generated on the front of the bulb 22, avoiding the accumulation of heat on the front of the bulb 22.

[0029] The bulb assembly 2 includes a bulb mounting base 21 and a bulb 22. The bulb mounting base 21 is slidably mounted on the mounting plate 1. The interior of the bulb mounting base 21 is hollow, forming a mounting hole 211 for mounting the bulb 22. A plurality of blocking units 23 are provided on the inner wall of the mounting hole 211.

[0030] In this embodiment, the blocking unit 23 is a steel ball. As a metal product, the steel ball has extremely high strength and rigidity. When installing and removing the light bulb 22, it can maintain its original shape and size, is not easily deformed, and improves the service life of the blocking unit 23. At the same time, the outer surface of the steel ball is an arc surface, which can make a transition when installing and removing the light bulb 22, improving the operation convenience when installing and removing the light bulb 22. Therefore, a spring piece 24 adapted to the blocking unit 23 is further provided on the lamp socket 21. Under the pressing of the spring piece 24, a part of the blocking unit 23 is exposed outside the mounting hole 211. When the light bulb 22 is inserted into the mounting hole 211, the light bulb 22 presses against the blocking unit 23 and overcomes the elastic force of the spring piece 24, thereby pushing open the blocking unit 23 to complete the installation. After the light bulb 22 is inserted into the mounting hole 211, the blocking unit 23 resets under the elastic force of the spring piece 24, contacts the outer surface of the light bulb 22 and generates resistance, preventing the installed light bulb 22 from loosening or falling off.

[0031] In this embodiment, the upper circumference of the mounting hole 211 increases from bottom to top to form a guiding portion 214. To prevent the light bulb 22 from shaking in the mounting hole 211, the radial dimension of the light bulb 22 is adapted to the inner diameter of the mounting hole 211. The guiding portion 214 is used to guide the light bulb 22 when it enters the mounting hole 211, preventing the light bulb 22 from being difficult to align with the mounting hole 211, and improving the convenience when installing the light bulb 22.

[0032] In this embodiment, an avoidance groove 213 that horizontally penetrates the side wall of the mounting hole 211 is further provided on the circumference of the mounting hole 211. The bottom height of the avoidance groove 213 is the same as the height of the installed edge 221. The avoidance groove 213 enables the human hand to directly contact the edge 221 when installing the light bulb 22, so that the force applied when installing the light bulb 22 acts on the edge 221, avoiding the force applied when installing the light bulb 22 from directly acting on the light bulb 22, and thereby reducing the risk of damage to the light bulb 22 during installation.

[0033] In this embodiment, the lamp assembly 2 further includes a plurality of pre-tightening assemblies 26. One end of the pre-tightening assembly 26 passes through the lamp socket 21 and is screwed to the mounting plate 1; the other end presses against the lamp socket 21. When the pre-tightening assembly 26 is used to adjust the position of the lamp socket 21, a pre-tightening force is applied to the lamp socket 21 to prevent the lamp socket 21 from randomly moving during adjustment, and the adjustment accuracy is improved.

[0034] Specifically, the pre-tightening assembly 26 includes an adjustment rod 261 screwed to the mounting plate 1. An elastic unit 262 is sleeved on the adjustment rod 261. One end of the elastic unit 262 elastically presses against the adjustment rod 261, and the other end is provided with a gasket 263. The elastic unit 262 presses against the bulb mount 21 via the gasket 263. By rotating the adjustment rod 261, the elastic unit 262 can be compressed or released to adjust the pre-tightening force applied by the pre-tightening assembly 26 to the bulb mount 21, thereby improving the compatibility and practicality of the pre-tightening assembly 26.

[0035] The bulb 22 is provided with a rib 221 that is compatible with the mounting hole 211. When the bulb 22 is installed, the rib 221 pushes away the blocking unit 23. After the bulb 22 is installed, the blocking unit 23 is reset under the pressure of the spring 24 to fix the bulb 22 and prevent the bulb 22 from falling out of the mounting hole 211. The outer layer of most existing bulbs 22 is made of glass or other materials and is fragile. The rib 221 is used to prevent the blocking unit 23 from directly pressing the bulb 22, causing damage to the bulb 22, thereby improving the reliability of the bulb 22.

[0036] In this embodiment, the bulb 22 includes a reflector cup, and the retaining edge 221 is disposed around the circumference of the reflector cup. The bulb mount 21 also includes a blocking portion 212 that matches the retaining edge 221. A clearance hole is formed between the blocking portions 212. The inner diameter of the reflector cup is smaller than the inner diameter of the clearance hole 215. The blocking portion 212 prevents the bulb 22 from falling out of the mounting hole 211, thereby improving the reliability of the bulb 22 installation. The smaller inner diameter of the reflector cup than the inner diameter of the clearance hole prevents the blocking portion 212 from partially blocking light, allowing full utilization of the light reflected by the reflector cup, thereby improving the lighting effect of the bulb 22.

[0037] The bulb assembly 2 also includes an eccentric shaft 25, which is in transmission connection with the bulb mount 21, driving the reciprocating movement of the bulb mount 21. By rotating the eccentric shaft 25, the user can easily adjust the position of the bulb mount 21 without complicated steps. This not only improves adjustment efficiency but also reduces operational difficulty, making it easy for even non-professionals to quickly master the technique.

[0038] In this embodiment, the bulb mount 21 is further provided with a plurality of adjustment holes 216, the extension direction of which is aligned with the adjustment direction of the bulb mount 21. The adjustment holes 216 not only provide adjustment margin for the bulb mount 21 but also serve as a guide during adjustment of the bulb mount 21, thereby improving the adjustment accuracy of the bulb mount 21.

[0039] In this embodiment, it further includes a heat insulation unit 4 fixedly installed on the mounting plate 1. The heat insulation unit 4 is disposed directly below the bulb 22, reducing the direct heat conduction of the heat generated by the bulb 22 to the surrounding environment, and reducing the potential damage caused by high temperature to the sensitive components or materials existing below the bulb 22, thereby improving the service life of the stage light.

[0040] According to the disclosure and teachings of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
