Description

Technical Field

[0002] Stage lights are important equipment in stage performances. Their structure generally includes a base chassis, a support arm, and a lamp head. The lamp head is the main part that integrates the light source and various optical modules. When installing the internal accessories of the lamp head, it is necessary to install a variety of optical components (such as focusing lenses, light-emitting lenses, and various light-effect lenses) on the light path of the light source. It is also required that the optical components and the light source, as well as the various optical components, are coaxial on the light path of the light source to ensure high-quality stage light output and light effect.

[0003] However, in actual assembly, due to the inevitable errors that often occur during the processing, manufacturing or assembly of the internal parts of the lamp head, it is easy to cause the optical components in the lamp head that pass through the light path of the light source to be misaligned. It is difficult for the optical components and the light source, as well as the various optical components, to be coaxial with each other in the light path of the light source. Therefore, there is a problem of poor centering inside the stage lamp head and it cannot be adjusted, which ultimately leads to poor light output of the stage lamp product and difficulty in achieving high-quality stage lighting effects.

[0020] The strip-shaped pulling hole passes through the through hole together with the sliding plate and passes out to the outside of the fixing bracket.

[0041] like Figures 1 to 7 As shown, a stage light of the present embodiment is convenient for correcting the optical path position of an optical module. The main structure of the stage light includes a base chassis 100, a support arm 200 and a lamp head 300. The support arm 200 is pivotally connected to the base chassis 100, and the lamp head 300 is pivotally connected between the support arms 200 on both sides. A light source 400 and a light-emitting lens 500 are installed inside the lamp head 300. An optical module 600 is installed between the light source 400 and the light-emitting lens 500. One or more optical elements are provided in the optical module 600, and the optical module 600 and the optical elements are located on the light path of the light source 400. In addition, a fixed bracket 1 and a correction bracket 2 are additionally installed in the lamp head 300. The optical module 600 is mounted and fixed on the correction bracket 2, and the correction bracket 2 is movably connected to the fixed bracket 1, and the moving direction of the correction bracket 2 on the fixed bracket 1 is perpendicular to the optical path of the light source 400. In addition, in order to facilitate locking the correction bracket 2, a locking piece is detachably provided between the fixed bracket 1 and the correction bracket 2, and the movable position of the correction bracket 2 on the fixed bracket 1 is locked by the locking piece.

[0042] It can be understood that the stage lamp structure of this embodiment has an additional fixed bracket 1 installed in the lamp head and a correction bracket 2 movably connected to the fixed bracket 1. The optical module 600 containing one or more optical elements in the lamp head 300 is mounted on the correction bracket 2. Since the movable direction of the correction bracket 2 in the lamp head is perpendicular to the optical path of the light source 400, it is equivalent to being able to radially displace the optical module 600 on the light path of the light source through the correction bracket 2. Therefore, when the optical element in the optical module 600 is not coaxial with the light source or other optical elements on the light path of the light source, the radial position of the optical module 600 on the light path of the light source inside the lamp head can be adjusted by controlling the movement of the correction bracket 2 on the fixed bracket 1, so as to facilitate the adjustment and correction of the coaxiality of the optical element in the optical module 600 on the light path of the light source. Furthermore, since a locking piece is detachably provided between the fixed bracket 1 and the correction bracket 2, when the optical module 600 is adjusted to a suitable position, the movable position of the correction bracket 2 on the fixed bracket 1 can be locked by the locking piece, and the optical elements in the optical module 600 can be locked in a working position that meets the coaxiality requirements, effectively solving the problem of centering deviation of the optical elements inside the stage light in the optical path.

[0043] In one embodiment, specifically, a guide assembly 4 is provided on the fixed bracket 1, and the guide assembly 4 extends in a direction perpendicular to the optical path of the light source. Accordingly, a sliding plate 5 is provided on the correction bracket 2, and the sliding plate 5 is slidably fitted in the guide assembly 4, so that the sliding plate 5 and the correction bracket 2 are guided by the guide assembly 4 to slide along the extension direction of the guide assembly 4, so that the optical module 600 mounted on the correction bracket 2 can smoothly generate radial displacement on the optical path of the light source.

[0044] In one embodiment, regarding the specific structure of the aforementioned guide assembly 4, the guide assembly 4 includes a through-hole 41 defined in the fixed bracket 1. The fixed bracket 1 is a sheet metal component, and clamping plates 42 are formed on opposite sides of the through-hole 41 through a process of punching and bending. Accordingly, the sliding plate 5 is also a sheet metal component, and positioning side plates 51 corresponding to the clamping plates 42 are extended from opposite sides of the sliding plate 5 through a process of punching and bending. When the correction bracket 2 is assembled to the fixed bracket 1, the two positioning side plates 51 pass through the through-hole 41 along with the sliding plate 5 and are slidably clamped between the two clamping plates 42. Therefore, the correction bracket 2 can move more stably under the restraining action of the clamping plates 42 on both sides, thereby improving the stability of the optical module 600 during movement.

[0045] In one embodiment, specifically, outward-extending clamping grooves 43 are formed on the left and right sides of the through hole 41, that is, a clamping groove 43 is formed between the inner wall of the top of the through hole 41 and the top side surface of the clamping plate 42. During assembly, the left and right ends of the sliding plate 5 passing through the through hole 41 are respectively fitted in the clamping grooves 43, and the bottom plate surface of the sliding plate 5 also slides with the top end surface of the clamping plate 42. In this structure, the clamping grooves 43 can be used to limit the up and down displacement of the sliding plate 5, and the sliding plate 5 can also slide more stably on the top side surfaces of the two clamping plates 42, ultimately ensuring that the optical module 600 can slide stably along the direction perpendicular to the light path of the light source along with the sliding plate 5.

[0046] In one embodiment, preferably, regarding the structure of the locking part, a strip hole 44 is respectively opened on each clamping plate 42, and the extension direction of the strip hole 44 is consistent with the sliding direction of the sliding plate 5 on the guide assembly 4, which is equivalent to the strip hole 44 extending in a direction perpendicular to the light path of the light source, and the locking part includes an adjusting screw 3. When the correction bracket 2 is assembled to the fixed bracket 1, the adjusting screw 3 passes through the strip hole 44 from the outside of the clamping plate 42 and then is inserted into the screw hole on the positioning side plate 51, and is threadedly connected with the screw hole on the positioning side plate 51. Therefore, when the adjusting screw 3 is fully tightened, the screw head of the adjusting screw 3 can press the clamping plate 42 and the positioning side plate 51 together. At this time, the sliding plate 5 cannot move, which is equivalent to locking the correction bracket 2 on the fixed bracket 1, and the optical module 600 can also be fixed in the working position. However, when it is necessary to adjust the position of the optical module 600, the pressing state of the adjusting screw 3 on the clamping plate 42 and the positioning side plate 51 can be loosened by rotating the adjusting screw 3. At this time, the adjusting screw 3 can be translated in the strip hole 44 of the clamping plate 42 along the length direction of the strip hole 44. Therefore, it is equivalent to using the strip hole 44 to stably limit the moving direction of the adjusting screw 3 and the sliding plate 5, ensuring that the sliding plate 5, the correction bracket 2 and the optical module 600 mounted on the correction bracket 2 can slide stably and accurately along the direction perpendicular to the light path of the light source, which is beneficial to ensure the accuracy when adjusting the coaxial position of the optical module 600.

[0047] In one embodiment, optionally, a strip-shaped pull hole 52 is provided on the slide plate 5, and the extension direction of the strip-shaped pull hole 52 is perpendicular to the translation direction of the slide plate 5 on the guide assembly 4. When the correction bracket 2 is assembled to the fixed bracket 1, the strip-shaped pull hole 52 passes through the through hole 41 together with the slide plate 5 and passes out to the outside of the fixed bracket 1. Therefore, the maintenance personnel can conveniently control the translation of the slide plate 5 by pressing the strip-shaped pull hole 52 on the slide plate 5 with their fingers outside the fixed bracket 1, so that the working position of the correction bracket 2 and the optical module 600 can be conveniently adjusted.

[0048] In one embodiment, optionally, the fixing bracket 1 is a sheet metal part, and a mounting position 11 is formed on the inner side of the fixing bracket 1 by multiple bending. During assembly, the correction bracket 2 is sleeved in the mounting position 11, thereby facilitating the positioning and installation of the correction bracket 2.

[0049] In one embodiment, in order to facilitate the installation of the fixing bracket 1 in the lamp holder 300, four circumferentially distributed connecting plates 12 are processed on the fixing bracket 1. The four connecting plates 12 are distributed at the four diagonals of the fixing bracket 1, and each connecting plate 12 is provided with a mounting hole for inserting screws. Each connecting plate 12 is connected to the lamp holder in the lamp holder 300 from different positions.

[0050] In one embodiment, the optical module 600 optionally includes multiple optical elements, and the number of correction brackets 2 is also set to multiple, and each correction bracket 2 carries a respective optical element in the optical module 60. The correction brackets 2 are arranged along the optical path of the light source 400 and are respectively movably connected to the fixed bracket 1. Therefore, the working position of each optical element can be adjusted by a different correction bracket 2, which can help to separately adjust the coaxiality of each optical element in the light path of the light source.

[0051] In one embodiment, optionally, the number of the correction brackets 2 is at least two, and in this embodiment, the number of the correction brackets 2 is two, and a guide rod 6 extending along the light path of the light source is connected between the two correction brackets 2, and a supporting plate 7 is slidably sleeved on the guide rod 6. Specifically, in this embodiment, the optical module 600 includes a magnifying glass 601 and a focusing lens 602 located in the light path of the light source, the magnifying glass 601 is mounted on the correction bracket 2, and the focusing lens 602 is mounted on the supporting plate 7, so that the focusing lens 602 can move back and forth along the light path of the light source. It can be seen that the above structure can not only adjust the radial displacement of the magnifying glass 601 and the focusing lens 602 in the light path of the light source and adjust the coaxiality through the correction bracket 2, but also ensure that the focusing lens 602 can normally move back and forth in the light path of the light source, ultimately ensuring the normal focusing function of the stage light.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
