Description

Technical Field

[0001] This invention relates to the field of light propagation technology, and in particular to a method and apparatus for drawing a reflector bowl curve. Background Technology

[0002] A cyclorama light is a lighting fixture specifically designed for stage lighting. Its main function is to provide uniform illumination to the stage curtain, helping to create a more complete and unified visual effect for the stage scene. The reflector is a crucial optical component of a cyclorama light; its main function is to reflect and focus the light emitted from the light source in a specific direction to create uniform illumination on the curtain.

[0003] Current traditional cyclorama lights typically employ a conventional symmetrical reflector bowl curve design, which concentrates light in the central area. This results in excessively high beam intensity in certain areas, creating noticeable bright spots and causing uneven light distribution. Furthermore, the flat placement of the LED chips makes the light perpendicular to the chips uncontrollable. This leads to multiple reflections and an uncertain point of impact on the wall. Even with the addition of light-blocking blades, the light cannot be sharply cut off, resulting in blurred light boundaries and ghosting. Summary of the Invention

[0004] This invention provides a method and apparatus for drawing reflector bowl curves to improve the light control effect of reflector bowl curves.

[0005] To address the aforementioned technical problems, embodiments of the present invention provide a method for drawing the curve of a reflective bowl, comprising:

[0006] Obtain scene requirements and light source parameters, obtain several reflector bowl segments based on the scene requirements, and obtain the target light intensity corresponding to the reflector bowl segments based on the light source parameters;

[0007] The reflection angle range of the reflector bowl segment is obtained based on the target light intensity, the light source parameters, and the preset light intensity integral equation.

[0008] Based on the reflection angle range and the preset reflector position information, the segmented curves of each reflector are obtained, and the target reflector curve is generated based on the segmented curves of the reflector.

[0009] This invention divides the reflector bowl into several segments according to scene requirements. Since different reflector bowl segments have different reflection positions and light intensities, the target light intensity of each reflector bowl segment is set by the light source parameters. The target light intensity clarifies the light intensity that each segment needs to reflect. The reflection angle range of each segment is determined based on the target light intensity. The reflector bowl curve of each segment is generated based on the reflection angle range, thus forming the overall target curve of the reflector bowl. By segmenting the reflector bowl according to scene requirements, the light distribution is ensured to meet the scene design requirements, thereby finely controlling the reflection path of each segment area, avoiding the light intensity concentration problem of traditional symmetrical reflectors, and improving the light control effect of the reflector bowl curve.

[0010] Furthermore, the light source parameters include total light intensity and light distribution curve. The step of obtaining several reflector bowl segments based on the scene requirements, and obtaining the target light intensity corresponding to each reflector bowl segment based on the light source parameters, includes:

[0011] Based on the scenario requirements, obtain the screen height and the number of light segments, and divide the screen into several screen segments on an average basis based on the screen height and the number of light segments.

[0012] Several reflector bowl segments are obtained based on the aforementioned several screen segments, and the target light intensity corresponding to each reflector bowl segment is obtained based on the total light intensity and the light distribution curve, wherein the screen segments and the reflector bowl segments correspond one-to-one.

[0013] This invention determines the screen height and the number of light segments based on scene requirements. Since screen height is an important reference parameter for lighting design, the screen is evenly divided into several segments of equal height according to the screen height and the number of light segments. Each segment corresponds to a specific lighting area, so that the lighting requirements of each segment can be calculated independently, thereby achieving more refined light intensity control.

[0014] Furthermore, obtaining the reflection angle range of the reflector bowl segments based on the target light intensity, the light source parameters, and the preset light intensity integral equation includes:

[0015] Calculate the light intensity offset of the reflector bowl segment based on the target light intensity and the total light intensity;

[0016] The reflection angle range of the reflector bowl segment is obtained based on the light intensity offset and the light intensity integral equation.

[0017] This invention calculates the light intensity offset and combines it with the light intensity integral equation to accurately determine the reflection angle range corresponding to each segment of the reflector bowl. By performing segmented calculations on the reflector bowl curve, the reflection path of the light from each segment of the reflector bowl can be significantly optimized, and the reflection angle range corresponding to each light segment can be accurately determined. This ensures that the light is distributed to the specific area of ​​the screen according to the design requirements, while improving the uniformity of the illumination distribution and the accuracy of the design.

[0018] Furthermore, the light intensity integral equation includes:

[0019]

[0020] in, For the target light intensity, Reflection angle , where is the central luminous intensity in the direction of light emission from the light source. This represents the light intensity shift. and The reflector bowl curvature coefficient is calculated based on the endpoints of the reflector bowl segments and the center of the light source.

[0021] Furthermore, the step of obtaining the segmented curves of each reflector bowl based on the reflection angle range and the preset reflector bowl position information, and generating the target reflector bowl curve based on the segmented reflector bowl curves, includes:

[0022] The height of the reflector bowl is obtained based on the position information of the reflector bowl, and the apex of the reflector bowl is determined based on the height of the reflector bowl;

[0023] Based on the vertex of the reflector bowl, the endpoints of the light segments of the reflector bowl segments, and the range of reflection angles, the corresponding incident light rays and reflected light rays of the reflector bowl segments are determined.

[0024] The reflecting surface is determined based on the incident light and reflected light from the reflector bowl, and a piecewise curve of the reflector bowl is generated based on the reflecting surface;

[0025] The target reflector curve is generated based on the segmented reflector curve.

[0026] This invention addresses the issue that each reflector segment corresponds to a reflection angle range and a light segment endpoint. By accurately calculating the incident and reflected light rays of each reflector segment based on the reflector's position information, reflection angle range, and light segment endpoints of the screen segment, the present invention determines the reflector segment curve and generates the overall target reflector curve based on the curves of each reflector segment. This enables precise control of the light reflection path, improving the uniformity of light distribution and design flexibility.

[0027] In a second aspect, the present invention provides an asymmetric reflector bowl curve drawing device, comprising: a segmentation module, a reflection angle determination module, and a drawing module;

[0028] The segmentation module is used to obtain scene requirements and light source parameters, obtain several reflector bowl segments based on the scene requirements, and obtain the target light intensity corresponding to the reflector bowl segment based on the light source parameters.

[0029] The reflection angle determination module is used to obtain the reflection angle range of the reflector bowl segments based on the target light intensity, the light source parameters, and the preset light intensity integral equation.

[0030] The drawing module is used to obtain the segmented curves of each reflector bowl based on the reflection angle range and the preset reflector bowl position information, and to generate the target reflector bowl curve based on the segmented curves of the reflector bowl.

[0031] Furthermore, the light source parameters include total luminous intensity and light distribution curve, and the segmentation module is used for:

[0032] Based on the scenario requirements, obtain the screen height and the number of light segments, and divide the screen into several screen segments on an average basis based on the screen height and the number of light segments.

[0033] Several reflector bowl segments are obtained based on the aforementioned several screen segments, and the target light intensity corresponding to each reflector bowl segment is obtained based on the total light intensity and the light distribution curve, wherein the screen segments and the reflector bowl segments correspond one-to-one.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] Example 1

[0052] See Figure 1 , Figure 1 This is a flowchart illustrating an asymmetric reflector bowl curve drawing method according to an embodiment of the present invention. The embodiment of the present invention provides an asymmetric reflector bowl curve drawing method, including steps 101 to 103, as detailed below:

[0053] Step 101: Obtain scene requirements and light source parameters, obtain several reflector bowl segments based on the scene requirements, and obtain the target light intensity corresponding to the reflector bowl segments based on the light source parameters;

[0054] In this embodiment, the light source parameters include total light intensity and light distribution curve. The step of obtaining several reflector bowl segments based on the scene requirements and obtaining the target light intensity corresponding to each reflector bowl segment based on the light source parameters includes:

[0055] Based on the scenario requirements, obtain the screen height and the number of light segments, and divide the screen into several screen segments on an average basis based on the screen height and the number of light segments.

[0056] Several reflector bowl segments are obtained based on the aforementioned several screen segments, and the target light intensity corresponding to each reflector bowl segment is obtained based on the total light intensity and the light distribution curve, wherein the screen segments and the reflector bowl segments correspond one-to-one.

[0057] In the example provided, the screen or wall is divided into several segments according to the needs of the scene, and the light intensity corresponding to each segment is calculated.

[0058] In this embodiment, the illumination range is determined based on the height of the screen in the actual scene; screen height is an important reference parameter for lighting design. The number of segments the screen is divided into is determined according to scene requirements (such as illumination uniformity and beam distribution). The more light segments, the higher the precision of the illumination distribution.

[0059] In this embodiment, by specifying the screen height and the number of light segments, basic data is provided for subsequent screen division and light intensity control.

[0060] In this embodiment, the screen is evenly divided into several segments of equal height according to the screen height and the number of light segments. Each segment corresponds to a specific lighting area, so that the lighting requirements of each segment can be calculated independently, thereby achieving more refined light intensity control.

[0061] In this embodiment, the reflector bowls are also divided into several corresponding light segments according to the division of the screen segments. Each reflector bowl segment is responsible for reflecting light to the corresponding screen segment, ensuring that each screen segment can receive precisely controlled light. By combining the total light intensity and the light distribution curve, the target light intensity of each reflector bowl segment can be accurately calculated, ensuring that the distribution of light on the screen meets the design requirements.

[0062] In this embodiment, the light source parameters include total luminous intensity and light distribution curve. The total luminous intensity emitted by the light source is the basis for calculating the target luminous intensity of each reflector segment. Based on the total luminous intensity, the total illumination can be allocated to each reflector segment. The light distribution curve provides information on the luminous intensity distribution of the light source in different directions. By using the light distribution curve and Lambert's cosine theorem to calculate the luminous intensity distribution in each direction, the target luminous intensity of the reflector segment in a specific direction can be calculated.

[0063] In this embodiment, the angle of the light source is defined as 0 degrees vertically, and the angle of the reflected light is calculated as the angle between the light source and the horizontal plane.

[0064] In this embodiment, after dividing the wall into X segments based on scene requirements, and combining the light distribution curve and a pre-selected theorem, the light intensity distribution of the light source can be obtained as a cosine distribution with the central light intensity at 0°, that is:

[0065] (1)

[0066] Where I represents the light intensity at any angle along the direction of light emission. This is the light intensity at the center of the direction in which the light source emits light. The angle between the direction of light emission from the light source and the horizontal plane is the reflection angle.

[0067] In this embodiment, based on the cosine distribution, the total luminous intensity of the light source is: If the corresponding light intensity needs to be evenly distributed on the screen, then the target light intensity required for each segment of the reflector bowl is:

[0068] (2)

[0069] in, The target light intensity for segmenting the reflector bowl.

[0070] In this embodiment, the screen height and the number of light segments are determined based on the scene requirements. Since the screen height is an important reference parameter for lighting design, the screen is evenly divided into several segments of equal height according to the screen height and the number of light segments. Each segment corresponds to a specific lighting area, so that the lighting requirements of each segment can be calculated independently, thereby achieving more refined light intensity control.

[0071] As a specific example in this embodiment of the invention, the screen height is obtained as 5M based on scene requirements, and the screen is divided into 10 equal segments according to scene requirements. Then, a corresponding reflector segment is determined based on the 10 screen segments. Finally, the target light intensity corresponding to each reflector segment is obtained based on the total light intensity and the light distribution curve. .

[0072] Step 102: Obtain the reflection angle range of the reflector bowl segment based on the target light intensity, the light source parameters, and the preset light intensity integral equation;

[0073] In this embodiment, after determining the target light intensity, since the positions of each segment in each reflector bowl relative to the light source are different, it is necessary to subtract the direct light intensity from the light intensity of the light source from the target light intensity to obtain the light intensity offset. The reflector bowl curve is determined based on the light intensity offset so that the light intensity reflected by the reflector bowl onto each screen plus the direct light intensity of the light source equals the target light intensity of each reflector bowl segment.

[0074] In this embodiment, obtaining the reflection angle range of the reflector bowl segments based on the target light intensity, the light source parameters, and a preset light intensity integral equation includes:

[0075] Calculate the light intensity offset of the reflector bowl segment based on the target light intensity and the total light intensity;

[0076] The reflection angle range of the reflector bowl segment is obtained based on the light intensity offset and the light intensity integral equation.

[0077] This invention calculates the light intensity offset and combines it with the light intensity integral equation to accurately determine the reflection angle range corresponding to each segment of the reflector bowl. By performing segmented calculations on the reflector bowl curve, the reflection path of the light from each segment of the reflector bowl can be significantly optimized, and the reflection angle range corresponding to each light segment can be accurately determined. This ensures that the light is distributed to the specific area of ​​the screen according to the design requirements, while improving the uniformity of the illumination distribution and the accuracy of the design.

[0078] In this embodiment, the light intensity integral equation includes:

[0079]

[0080] in, For the target light intensity, Reflection angle , where is the central luminous intensity in the direction of light emission from the light source. This represents the light intensity shift. and The reflector bowl curvature coefficient is calculated based on the endpoints of the reflector bowl segments and the center of the light source.

[0081] In this embodiment, after obtaining the light intensity offset of each reflector segment, the angle range of each reflector curve is calculated based on the light intensity offset, the center light intensity of the light source emission direction, and the total light intensity.

[0082] Please refer to Figure 2 , Figure 2 This is a schematic diagram of a segmented reflector bowl provided in an embodiment of the present invention.

[0083] In this embodiment, the vertical direction is the screen, which is divided into 10 equal segments, thus corresponding to 10 reflector segments. Each reflector segment has two endpoints. The reflection angle range for each reflector segment is calculated by connecting the endpoints of the reflector segment to the center of the light source, determining the angle between the direction of the light source center directly hitting the two endpoints of the reflector segment and the horizontal plane. Based on this angle, the reflector's radian coefficient is calculated. For example, in the second reflector segment, the angles between the direction of the light source center directly hitting the two endpoints of the reflector segment and the horizontal plane are 13 degrees and 11 degrees respectively. for , for According to the integral equation of light intensity, This allows us to deduce the range of reflection angles for the second reflector segment.

[0084] Step 103: Based on the reflection angle range and the preset reflector position information, obtain the segmented curves of each reflector, and generate the target reflector curve based on the segmented curves of the reflector.

[0085] In this embodiment, the step of obtaining the segmented curves of each reflector bowl based on the reflection angle range and preset reflector bowl position information, and generating the target reflector bowl curve based on the segmented reflector bowl curves, includes:

[0086] The height of the reflector bowl is obtained based on the position information of the reflector bowl, and the apex of the reflector bowl is determined based on the height of the reflector bowl;

[0087] Based on the vertex of the reflector bowl, the endpoints of the light segments of the reflector bowl segments, and the range of reflection angles, the corresponding incident light rays and reflected light rays of the reflector bowl segments are determined.

[0088] The reflecting surface is determined based on the incident light and reflected light from the reflector bowl, and a piecewise curve of the reflector bowl is generated based on the reflecting surface;

[0089] The target reflector curve is generated based on the segmented reflector curve.

[0090] In this embodiment, the height of the reflector bowl is determined by the position information of the reflector bowl, so as to determine the apex of the reflector bowl. The apex of the reflector bowl is the highest point of the reflector bowl and also the starting point of the reflected light.

[0091] In this embodiment, the incident light ray is the light rays that enter the surface of the reflector bowl from the light source or other positions. The reflected light ray is the light rays after reflection on the surface of the reflector bowl. The directions and positions of the incident and reflected light rays can be calculated using the apex of the reflector bowl, the endpoints of the light segments, and the range of reflection angles. Then, the normal position can be determined based on the directions and positions of the incident and reflected light rays. After determining the detection position, the reflecting surface can be determined, and segmented curves corresponding to each reflector bowl segment are generated based on the reflecting surface. Finally, the target reflector bowl curve, i.e., the overall reflector bowl curve, is drawn based on the segmented curves of all reflector bowl segments to ensure that the reflector bowl reflects light in the expected manner.

[0092] In this embodiment, the shape of the reflective surface of the reflector bowl is determined according to the geometric relationship between the incident light and the reflected light, and the light segment curve of the reflector bowl is generated based on the geometry of the reflective surface.

[0093] In this embodiment, since each reflector segment corresponds to a reflection angle range and a light segment endpoint, the incident and reflected light rays of each reflector segment are accurately calculated based on the reflector's position information, reflection angle range, and light segment endpoint of the screen segment. This determines the reflector segment curve, and the overall target reflector curve is generated based on the curves of each reflector segment. This enables precise control of the light reflection path, improves the uniformity of the illumination distribution, and enhances the design flexibility.

[0094] In this embodiment, the reflector bowl is divided into several reflector bowl segments according to scene requirements. Since the reflection positions and light intensities of different reflector bowl segments are different, the target light intensity of each reflector bowl segment is set by the light source parameters. The required light intensity to be reflected by each light segment is determined by the target light intensity. The reflection angle range of each segment is determined according to the target light intensity. The reflector bowl curve of each segment is generated by the reflection angle range, thereby forming the target curve of the reflector bowl as a whole. By segmenting the reflector bowl according to scene requirements, the light distribution is ensured to meet the scene design requirements, so as to finely control the reflection path of each segment area, avoid the light intensity concentration problem of traditional symmetrical reflector bowls, and improve the light control effect of the reflector bowl curve.
