Description

[0002] In the field of stage art, lighting has always been a key element in shaping visual beauty and creating an atmosphere. To meet the requirements of stage performances, a relatively large number of lenses are needed inside stage lights. These lenses cooperate with each other to cause various changes in light, thereby creating different atmospheres and visual effects.

[0003] As an important part of stage lights, the lens structure is usually installed on a rotatable bracket and can be quickly rotated and tilted by a motor drive to change the projection direction and angle of light. Among them, the installation design and material of the lens structure are key factors affecting the stage lighting effect. However, due to problems such as unreasonable lens layout in existing stage lights, the presentation effect of light and shadow is restricted, resulting in poor light and shadow effects and affecting the user experience. At the same time, with the popularity and development of high-power stage lights, more and more stage lights use high-power LED lights. Due to the relatively large power of the light source, the light projected onto the stage is too strong or dazzling, lacking softness, and the color temperature of the light cannot be changed, which will greatly affect the stage effect and is also likely to cause eye discomfort to actors and audiences. Moreover, a relatively large-power LED light will also generate a large amount of heat during use. If the heat cannot be discharged in time, it will seriously damage the components inside the stage light and affect the service life of the stage light.

[0032] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1

[0034] Please refer toFigures 1-4 , the lens structure for stage lights of the present application includes a mounting fixing plate 1, a light collecting component 2, a color disk component 3, a light homogenizing component 4, and a lens component 5. The light collecting component 2, the color disk component 3, the light homogenizing component 4, and the lens component 5 are sequentially arranged above the mounting fixing plate 1 from bottom to top.

[0035] Specifically, as Figure 2 shown, an LED light source 11 is provided on the mounting fixing plate 1. The light emitting surface of the LED light source 11 is circular and located at the center of the mounting fixing plate 1. Exemplarily, the mounting fixing plate 1 is circular as a whole, and the light emitting surface of the LED light source 11 is concentric with the mounting fixing plate 1. The light collecting component 2, the light homogenizing component 4, and the lens component 5 are sequentially arranged directly above the LED light source 11 from bottom to top. Among them, the LED light source is an LED lamp that emits white diffused light.

[0036] The light collecting component 2 is arranged directly above the LED light source 11. Specifically, the light collecting component 2 includes a mounting base 21 and a light collecting lens 22. The mounting base 21 is arranged on the mounting fixing plate 1, and the light collecting lens 22 is arranged on the mounting base 21. Exemplarily, as Figure 3 shown, the mounting base 21 includes a connected fixing part 211 and a mounting part 212. The fixing part 211 and the mounting part 212 are integrally in a gantry structure. Two fixing parts 211 are provided and are relatively arranged on both sides of the mounting part 212. The fixing part 211 is provided with screw holes 213, and the mounting fixing plate 1 is also correspondingly provided with screw holes. The mounting base 21 is fixed on the mounting fixing plate 1 by screws.

[0037] The light collecting lens 22 is arranged on the mounting part 212. Specifically, a circular through hole is provided on the mounting part 212. When the mounting base 21 is fixed on the mounting fixing plate 1, the circular through hole is directly opposite to the LED light source 11. The light collecting lens 22 is arranged at the circular through hole, so that the light collecting lens 22 is directly opposite to the LED light source 11, so that the diffused light rays emitted by the LED light source can reach the light collecting lens 22, and the diffused light rays are converted into parallel light rays and emitted through the light collecting lens 22.

[0038] The color disk component 3 is arranged above the light collecting component 2. Specifically, the color disk component 3 includes a driving part 31, a connecting flange 32, and a color disk 33. The driving part 31 is fixed on the mounting fixing plate 1, and the connecting flange 32 is respectively connected to the driving part 31 and the color disk 33. Exemplarily, as Figure 2As shown, the driving part 31 includes a driving motor 311 and an output shaft 312. The driving motor 311 is arranged on the mounting plate 1. The output shaft 312 is connected to the driving motor 311, and the extension direction of the output shaft 312 is perpendicular to the mounting plate 1. The connecting flange 32 is sleeved on the upper end of the output shaft 312, and the color disk 33 is connected to the connecting flange 32. When the driving motor 311 is started, the output shaft 312 rotates, driving the connecting flange 32 and the color disk 33 to rotate synchronously, so that the color disk 33 can rotate to the top of the LED light source 11. When the scattered light emitted by the LED light source is converted into parallel light by the light collecting lens 22, it passes through the color disk 33, thereby changing the color and color temperature of the light, thereby adding a gorgeous effect to the light and shadow, and meeting the requirements of the stage scene for color temperature.

[0039] In order to enrich the color of light and shadow as much as possible and expand the color temperature range of light spots, for example, Figure 4 As shown, the color disk 33 includes a first color patch 331, a second color patch 332 and a CTO patch 333, wherein the first color patch 331, the second color patch 332 and the CTO patch 333 are sequentially arranged along the circumferential direction of the connecting flange 32, and the area of ​​the CTO patch 333 is much larger than the area of ​​the first color patch 331 and / or the second color patch 332, so that the color temperature range of the CTO can reach 3200K-6500K, and can provide comfortable and natural light in different places and environments to meet different needs and preferences. Among them, the colors of the first color patch 331 and the second color patch 332 are different. Exemplarily, the color of the first color patch 331 is rose red, and the color of the second color patch 332 is blue.

[0040] The light homogenizing component 4 and the lens component 5 are sequentially arranged from bottom to top directly above the light receiving component 2. Specifically, the light homogenizing component 4 includes a plurality of mounting posts 41, a mounting plate 42 and a light homogenizing lens 43, wherein the plurality of mounting posts 41 are arranged beside the LED light source 11 and are perpendicular to the mounting fixing plate 1, the mounting plate 42 is fixed to the top of the mounting posts 41, and the light homogenizing lens 43 is arranged on the mounting plate 42 and directly facing the LED light source 11.

[0041] Specifically, one end of the mounting post 41 is fixed on the mounting fixing plate 1, and the other end is provided with a threaded through-hole. The mounting plate 42 is provided with corresponding mounting through-holes. By passing screws through the mounting plate 42 and the mounting post 41 in sequence, the mounting plate 42 is fixed to the top of the mounting post 41. In order to simplify the structure while stabilizing the mounting plate 42, the number of the mounting posts 41 is three. By providing three support points for the mounting plate 42 to form a stable triangular force, the mounting plate 42 can be stably fixed on the mounting post 41. The mounting plate 42 is integrally circular and the center is hollow. The light homogenizing lens 43 is arranged in the hollow part and faces the LED light source 11. When the light emitted by the LED light source passes through the color disk 33, it is transmitted to the light homogenizing lens 43. The strong light is converted into soft light by the light homogenizing lens 43, thus effectively solving the problem of eye discomfort caused by dazzling light.

[0042] It should be noted that in order to facilitate the output rotating shaft 312 to extend out while positioning the relative positions of the color disk and the mounting plate 42, the mounting plate 42 is also provided with a shaft through-hole. When the output rotating shaft 312 and the mounting plate 42 are fixed, the top end of the output rotating shaft 312 extends out of the shaft through-hole.

[0043] The lens assembly 5 can move up and down relative to the LED light source 11, so as to adjust the size of the light spot. Specifically, the lens assembly 5 includes a lifting driving mechanism 51, a mounting disk 52 and a Fresnel lens 53. In order to enable the Fresnel lens 53 to lift steadily, two lifting driving mechanisms 51 are provided. As Figure 2 shown, the lifting driving mechanisms 51 are arranged oppositely on both sides of the LED light source 11. The mounting disk 52 is arranged on the lifting driving mechanisms 51 and moves up and down under the drive of the lifting driving mechanisms 51. The Fresnel lens 53 is arranged on the mounting disk 52 and is located directly above the LED light source 11. Thus, when the light emitted by the LED light source passes through the light homogenizing lens 43, it can reach the Fresnel lens 53.

[0044] More specifically, the lifting drive mechanism 51 includes a lifting motor 511 and a threaded lead screw 512. The lifting motor 511 is fixed on the mounting fixing plate 1, and the threaded lead screw 512 is connected to the output end of the lifting motor 511; a threaded flange is mounted on the mounting plate 52, and the threaded flange is connected to the threaded lead screw 512. The Fresnel lens 53 is fixedly connected to the mounting plate 52. When the lifting motor 511 is driven, it drives the threaded lead screw 512 to rotate, thereby driving the threaded flange to perform a linear up-and-down movement, and further driving the mounting plate 52 and the Fresnel lens 53 to perform a synchronous lifting movement. By driving the Fresnel lens 53 to perform a lifting movement, the distance between the Fresnel lens 53 and the light homogenizing lens 43 (or the LED light source) is changed, thereby changing the size of the light spot. Exemplarily, when the Fresnel lens 53 descends, the distance between the Fresnel lens 53 and the light homogenizing lens 43 (or the LED light source) becomes smaller, making the light spot larger. Conversely, when the Fresnel lens 53 ascends, the light spot becomes smaller. By changing the size of the light spot, the dynamic light and shadow effects of the stage light are enriched.

[0045] In the first embodiment, the lens structure for a stage light of the present application includes a mounting fixing plate, an LED light source, a light collecting assembly, a color disk assembly, a light homogenizing assembly, and a lens assembly. When the white diffused light emitted by the LED light source is collected by the light collecting lens, it becomes parallel white light, and then after passing through the color disk to change the color and color temperature of the light, it is further converted into softer light by the soft light lens, and finally through the lifting Fresnel lens, so that the projected gorgeous light spot can change in size. Through the mutual cooperation of the above-mentioned multiple components, the color and dynamic effects of the light and shadow are further enriched. Compared with the existing lens structure for a stage light, the solution provided by the present application can present rich color dynamic light and shadow effects by optimizing the lens structure, greatly improving the use experience of the stage light, making the strong light emitted by the high-power LED light source softer, effectively solving the problem of eye discomfort caused by the overly strong or dazzling light of the existing stage light, and can effectively change the color temperature of the light to meet the requirements for the color temperature at the stage site.

[0046] Embodiment Two

[0047] With the popularity and development of high-power stage lights, more and more stage lights use high-power LED lights. High-power LED lights will also generate a large amount of heat during use. If the heat cannot be discharged in time, it will seriously damage the components inside the stage light and affect the service life of the stage light. To solve the above problems, the present application proposes a corresponding solution. Please refer to Figures 1-4 , specifically as follows:

[0048] Based on the structure of the first embodiment above, the lens structure for stage lights further includes a heat dissipation component 6, and the heat dissipation component 6 is arranged around the LED light source. Specifically, as Figure 1 shown, the heat dissipation component 6 includes a plurality of heat dissipation fans 61, and the plurality of heat dissipation fans 61 are arranged in a convection manner around the LED light source and are connected to the LED light source. Exemplarily, there are 4 heat dissipation fans 61, and the 4 heat dissipation fans 61 are symmetrically arranged on the opposite side of the LED light source. Among them, 2 of the heat dissipation fans intake air, and the blown air passes through the LED light source and then is blown out by the other 2 heat dissipation fans. By arranging the heat dissipation fans 61, the heat around the LED light source is discharged in time, effectively reducing the temperature around the LED light source.

[0049] To further improve the heat dissipation effect, the heat dissipation component 6 further includes a radiator copper substrate 62, a copper heat pipe 63, and a plurality of heat dissipation fins. The radiator copper substrate 62 is arranged below the mounting fixing plate 1 and is connected to the LED light source 11, that is, the LED light source is mounted on the radiator copper substrate 62. The plurality of heat dissipation fins are arranged below the radiator copper substrate 62. One end of the copper heat pipe 63 is connected to the heat dissipation fins, and the other end is connected to the radiator copper substrate 62 for conducting the heat on the radiator copper substrate 62 to the plurality of heat dissipation fins. At this time, the 4 heat dissipation fans 61 are arranged in a convection manner around the heat dissipation fins.

[0050] After the heat generated by the LED light source is transferred to the radiator copper substrate 62, the copper heat pipe will quickly absorb the heat on the radiator copper substrate 62 and transfer the heat to the plurality of heat dissipation fins. Then 2 of the heat dissipation fans intake air. After the wind blows through the heat dissipation fins, it is blown out by 2 heat dissipation fans, thereby quickly dissipating the heat on the heat dissipation fins.

[0051] In the embodiment of the present application, through the cooperation of the radiator copper substrate and the copper heat pipe, the heat generated by the LED light source is quickly transferred to the heat dissipation fins, and the heat dissipation fins are cooled by the convection heat dissipation fans. Since the area of the plurality of heat dissipation fins is large, the heat dissipation effect is greatly improved, thereby effectively reducing the temperature around the LED light source and extending the service life.

[0052] Embodiment Three

[0053] Corresponding to the above-mentioned first embodiment and second embodiment, the present application further provides a stage light. Please refer to Figures 1-4 , specifically:

[0054] Based on the structures of the above-mentioned First Embodiment and Second Embodiment, the stage light provided by the present application includes a lamp housing and the above-mentioned lens structure for stage lights. A receiving inner cavity is provided in the lamp housing, and the lens structure for stage lights is arranged at the receiving inner cavity.

[0055] For the specific structure of the lens structure for stage lights, please refer to the above-mentioned First Embodiment and Second Embodiment, which will not be elaborated here.

[0056] In the description of the present application, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0057] For the convenience of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "beneath other devices or structures" afterwards. Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations should be made for the spatial relative descriptions used here.

[0058] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
