Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting display technology, and in particular to a stage lighting system. Background Technology
[0002] Stage lights are commonly used in theaters, stadiums, television stations, studios, concert halls, stadiums, and other venues. These venues require a high color rendering index (CRI). The higher the CRI, the better, as it is necessary to accurately reproduce the original color of a substance. Many venues require a CRI greater than 95, or even a CRI of 100.
[0003] However, current stage lights typically use metal halide lamps, which have a theoretical color rendering index (CRI) of 90. In actual use, however, the CRI is affected by various conditions, especially at low color temperatures and low brightness levels, causing it to drop significantly, often falling below 70. Therefore, improving the CRI of stage lights under low color temperature and low brightness conditions is a pressing issue. Utility Model Content

[0011] The first filter is a magenta filter, the second filter is a yellow filter, and the third filter is a cyan filter.
[0012] In some embodiments, the two filter halves of the first filter are comb-shaped at one end facing the optical path transmission direction.
[0013] In some embodiments, the imaging assembly includes a pattern sheet, a focusing lens, a zoom lens, and an objective lens arranged sequentially along the optical path transmission direction.

[0022] The technical solution provided by this utility model has the following advantages compared with the prior art:
[0023] The stage lighting system provided in this embodiment of the utility model includes a stage light and a driving structure. The stage light includes a light source, a reflector, a color temperature mixing component, and an imaging component. The driving structure is mechanically connected to the color temperature mixing component. The reflector, color temperature mixing component, and imaging component are arranged sequentially along the light path transmission direction of the light source. The color temperature mixing component includes a first filter, a second filter, a third filter, and a color temperature adjustment filter. The first filter, second filter, third filter, and color temperature adjustment filter are arranged staggered sequentially along the light path transmission direction. Each filter includes two filter halves, which are arranged opposite each other on both sides of the light path transmission direction. The color temperature adjustment filter includes two color temperature adjustment filter halves, which are arranged opposite each other on both sides of the light path transmission direction. The first filter is a magenta filter, the second filter is a yellow filter, and the third filter is a cyan filter. By configuring a color temperature mixing component including a first filter, a second filter, a third filter, and a color temperature adjustment filter, the first filter is a magenta filter.

Therefore, using a magenta filter that has not yet formed magenta light for filtering can improve the CRI of the light source. Additionally, the color temperature adjustment filter adjusts the color temperature of the light emitted by the light source. When adjusted to low color temperature and low brightness conditions, such as approximately 5600K and reducing the brightness of the white spot of the light source from 100% to 40%, adjusting the magenta filter to approximately one-fifth of its travel can achieve a CRI of over 70 for the stage lights under these conditions. Furthermore, the linear adjustment control function of the magenta filter can be used to achieve consistency across multiple stage lights. Attached Figure Description

Detailed Implementation
[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0035] The stage lighting system provided in this embodiment of the invention includes a color temperature mixing component comprising a first filter, a second filter, a third filter, and a color temperature adjustment filter. The first filter is a magenta filter. When the light emitted by the magenta filter has not yet developed a magenta color, its wavelength is similar to the wavelength required to improve the color rendering index (CRI). Therefore, using the magenta filter, which has not yet formed magenta light, for filtering can improve the CRI of the light source. Furthermore, the color temperature adjustment filter adjusts the color temperature of the light emitted by the light source. When adjusted to low color temperature and low brightness, for example, at approximately 5600K and the brightness of the white spot of the light source is reduced from 100% to 40%, the stage lighting system can achieve a CRI of over 70 under these conditions when the magenta filter is adjusted to approximately one-fifth of its travel. Moreover, the linear adjustment control function of the magenta filter can be used to achieve consistency across multiple stage lights.
[0036] The stage lighting system provided in the embodiments of this utility model will be described exemplarily below with reference to the accompanying drawings.
[0037] Figure 1 This is a structural schematic diagram of a stage lighting system provided in an embodiment of the present utility model. Figure 2 This is a schematic diagram of the optical path structure of a stage lamp provided for an embodiment of this utility model. Figure 1 and Figure 2 As shown, the stage lighting system includes a stage light 10 and a driving structure 11; the stage light 10 includes a light source 12, a reflector 13, a color temperature mixing component 14, and an imaging component 15, and the driving structure 11 is mechanically connected to the color temperature mixing component 14; the reflector 13, the color temperature mixing component 14, and the imaging component 15 are arranged sequentially along the optical path transmission direction X of the light source 12;
[0038] The color mixing and color temperature component 14 includes a first filter 141, a second filter 142, a third filter 143, and a color temperature adjustment filter 144. The first filter 141, the second filter 142, the third filter 143, and the color temperature adjustment filter 144 are arranged in a staggered manner along the optical path transmission direction X.
[0039] Each of the filters includes two filter halves, which are disposed opposite to each other on both sides of the optical path transmission direction X; the color temperature filter 144 includes two color temperature filter halves, which are disposed opposite to each other on both sides of the optical path transmission direction X.
[0040] The light source 12 can be a traditional light source 12 or an LED light source 12; the first filter 141 is a magenta filter, the second filter 142 is a yellow filter, and the third filter 143 is a cyan filter. The three filters, namely the magenta filter, the yellow filter and the cyan filter, are distributed in a staggered manner along the optical path transmission direction X.
[0041] The drive structure 11 is mechanically connected to the color temperature mixing component 14. During operation, the drive structure 11 is used to drive the filter in the color temperature mixing component 14 to move into the optical path for filtering, and the drive structure 11 is also used to drive the color temperature adjusting chip 144 in the color temperature mixing component 14 to move into the optical path for color temperature adjustment, thereby presenting a variety of lighting effects.
[0042] The reflector bowl 13 is arranged around the light source 12, and the light-transmitting area of the color temperature mixing component 14 can be the color mixing area 19. Within the color mixing area 19, the closer to the reflector bowl 13, the more uniform the color mixing effect; the farther away from the reflector bowl 13, the less uniform the color mixing effect. Therefore, to make the color rendering index more consistent across the entire light spot, the first filter 141, i.e., the magenta filter, in the color temperature mixing component 14 is installed closest to the reflector bowl 13 among all the filters. When the light formed by the magenta filter has not yet developed a magenta color, its wavelength is similar to the wavelength required to improve the color rendering index. Therefore, using the magenta filter, which has not yet formed magenta light, for filtering can improve the color rendering index of the light source 12.
[0043] Specifically, each filter includes two filter halves, which are disposed opposite each other on both sides of the optical path transmission direction; the color temperature filter 144 includes two color temperature filter halves, which are disposed opposite each other on both sides of the optical path transmission direction.
[0044] For example, such as Figure 3 The first filter 141 shown includes two first filter halves, namely magenta half, exemplarily indicated by reference numeral 1411; the second filter 142 includes two second filter halves, namely yellow half; the third filter 143 includes two third filter halves, namely cyan half; and the color temperature adjuster 144 includes two color temperature adjuster halves, exemplarily indicated by reference numeral 1441. In operation, the driving structure 11 can drive the two filter halves of each filter to move relative to each other from both sides of the optical path transmission direction X, entering the optical path and approaching each other. Similarly, the driving structure can drive the two color temperature adjuster halves to move relative to each other from both sides of the optical path transmission direction X, entering the optical path and approaching each other.
[0045] For example, Figure 3 This is a schematic diagram of a color temperature mixing component not entering the optical path, provided by an embodiment of the present invention. Figure 4 This is a schematic diagram of the optical path of a color temperature mixing component provided in an embodiment of the present invention. (See Figure 3.) Figure 4As shown, when the first filter 141, i.e., the magenta filter, is adjusted to approximately one-fifth of its travel, meaning that the two halves of the first filter 1411 are each within one-fifth of the reflective range of the reflector bowl 13, the light emitted by the two halves of the first filter 1411 has not yet shown a magenta color. Similarly, when the color temperature adjustment filter 144 is adjusted to approximately one-third of its travel, meaning that the two halves of the color temperature adjustment filter 1441 are each within one-third of the reflective range of the reflector bowl 13, adjusting the color temperature of the light emitted by the light source 12 at these times helps to improve the color rendering index (CRI) of the stage light 10. Practical experience has shown that even at low color temperatures and low brightness, such as when adjusted to approximately 5600K and the brightness of the white spot of the light source 12 is reduced from 100% to 40%, a CRI greater than or equal to 70 can be fully achieved.
[0046] It should be noted that the travel of each filter and color temperature control plate can be adjusted in this embodiment of the invention to ensure that the stage light 10 achieves the optimal display effect.
[0047] Therefore, the stage lighting system provided in this embodiment of the invention, by setting a color temperature mixing component including a first filter, a second filter, a third filter, and a color temperature adjustment filter, wherein the first filter is a magenta filter, when the light formed by the magenta filter has not yet shown a magenta color, its wavelength is similar to the wavelength required to improve the color rendering index. Therefore, by using the magenta filter, which has not yet formed magenta light, for filtering, the color rendering index of the light source can be improved. In addition, the color temperature adjustment filter adjusts the color temperature of the light emitted by the light source. When adjusted to a low color temperature and low brightness, for example, adjusted to about 5600K, and the brightness of the white spot of the light source is reduced from 100% to 40%, when the magenta filter is adjusted to about one-fifth of its travel, the stage lighting can achieve a color rendering index of over 70 under these conditions. Furthermore, the linear adjustment control function of the magenta filter can be used to achieve consistency among multiple stage lights.
[0048] In some embodiments, Figure 5 This is a schematic diagram of the light transmission cross-section of a first filter provided in an embodiment of the present invention. Figure 5 As shown, the two filter halves 1411 of the first filter 141 have a comb-like shape at one end facing the optical path transmission direction X.
[0049] Specifically, to prevent the two first filter halves 1411, i.e., the magenta half-pieces, from entering the optical path and significantly affecting the luminous flux, the ends of the two first filter halves 1411 closest to the optical path can be configured in a comb-like shape. For example... Figure 5As shown, from the direction of the optical path, a light-transmitting section 21 is formed in the middle of the two first filter halves 1411. The shaded part on the first filter halves 1411 is the coating area, and the blank part between the comb teeth is completely light-transmitting. Therefore, when the two first filter halves 1411 enter a small distance of the optical path (i.e., before magenta light is formed), the effect on color is small and negligible, and consequently the effect on light flux is also small and negligible.
[0050] In some embodiments, Figure 6 This is a schematic diagram of the light transmission cross section of a color temperature adjustment film provided for an embodiment of this utility model.
[0051] Specifically, to prevent the two color temperature filter halves 1441 from significantly affecting the luminous flux when entering the optical path, the ends of the two color temperature filter halves 1441 closest to the optical path can be configured in a comb-like shape. For example... Figure 6 As shown, from the optical path direction, a light-transmitting section 22 is formed in the middle of the two color temperature control half-body 1441. The shaded area on the two color temperature control half-body 1441 is the coating area, and the blank area between the comb teeth is completely light-transmitting. Therefore, the two color temperature control half-body 1441 enters a small distance in the optical path, and the effect on the color temperature is small and negligible. Consequently, the effect on the light flux is also small and negligible.
[0052] In some embodiments, such as Figure 2 As shown, the imaging assembly 15 includes a patterned sheet 151, a focusing lens 152, a zoom lens 153, and an objective lens 154 arranged sequentially along the optical path transmission direction X. The area where the patterned sheet 151 is located is the imaging area 20.
[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the driving structure 11 includes a color mixing driving structure 111, which is used to drive the filter to move.
[0054] Thus, the two filter halves of the filter are driven by the color mixing drive structure 111 to move relative to each other from both sides of the light path transmission direction X and enter the light path, thereby adjusting the stroke of each filter and presenting a variety of lighting effects.
[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the color mixing driving structure 111 includes a first driving structure 1111, a second driving structure 1112, and a third driving structure 1113;
[0056] The first driving structure 1111 is used to drive the first filter 141 to move, the second driving structure 1112 is used to drive the second filter 142 to move, and the third driving structure 1113 is used to drive the third filter 143 to move.
[0057] Specifically, the first driving structure 1111 drives the two filter halves of the first filter 141 to move relative to each other from both sides of the optical path transmission direction X into the optical path, thereby adjusting the stroke of the first filter 141; the second driving structure 1112 drives the two filter halves of the second filter 142 to move relative to each other from both sides of the optical path transmission direction X into the optical path, thereby adjusting the stroke of the second filter 142; and the third driving structure 1113 drives the two filter halves of the third filter 143 to move relative to each other from both sides of the optical path transmission direction X into the optical path, thereby adjusting the stroke of the third filter 143.
[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, the driving structure includes a color temperature adjustment driving structure 112, which is used to drive the color temperature adjustment plate 144 to move.
[0059] Specifically, by driving the two halves of the color temperature adjustment plate 144 from opposite sides of the light path transmission direction X through the color temperature adjustment driving structure 112, the travel of the color temperature adjustment plate 144 can be adjusted, thereby achieving the adjustment of the color temperature of the light source 12.
[0060] In some embodiments, such as Figure 1 As shown, the stage lighting 10 system also includes:
[0061] The control panel 16 is communicatively connected to the drive structure 11.
[0062] Specifically, during operation, the user can send drive signals to the drive structure 11 via the control panel 16. After receiving the drive signals, the drive structure 11 drives the filter and color temperature adjustment plate 144 in the color mixing and color temperature component 14 to move, that is, to adjust the stroke of the filter and color temperature adjustment plate 144, thereby adjusting the display parameters of the stage light 10. The display parameters may include the display index and color temperature.
[0063] In some embodiments, continue as follows Figure 1 As shown, the control panel 16 includes a user operation panel 17 and a control unit 18, and the control unit 18 is communicatively connected to the user operation panel 17 and the drive structure, respectively.
[0064] Specifically, the user operation panel 17 is used to receive display parameters input by the user. After receiving the display parameters, the control unit 18 determines the corresponding drive signal according to the display parameters and outputs the drive signal to the drive structure 11 to drive the filter and color temperature adjustment plate 144 in the color mixing and color temperature component 14 to move, that is, to adjust the stroke of the filter and color temperature adjustment plate 144, so that the stage light 10 can work according to the input display parameters.
