Description

Technical Field

[0001] The present invention relates to the technical field of light propagation, and in particular to a method and device for drawing a reflective bowl curve. Background Art

[0002] The stage skylight is a lamp specially used for stage lighting. Its main function is to provide uniform lighting for the stage curtain, helping the visual effect of the stage scene to be more complete and unified. The reflector is a very important optical component in the stage skylight. Its main function is to reflect and concentrate the light emitted by the light source in a specific direction to form uniform lighting on the curtain.

[0003] At present, traditional skylights usually adopt a conventional symmetrical reflective bowl curve design, which concentrates the light in the central area, resulting in excessive intensity of the light beam in some areas to form obvious bright spots, resulting in uneven light distribution. In addition, due to the flat placement of the lamp bead board, the light perpendicular to the lamp beads is uncontrollable, resulting in the inability to determine the landing point of the light on the wall after multiple reflections. The flat placement design of the lamp beads makes it impossible to accurately control the light perpendicular to the lamp beads, resulting in uncertain landing points on the wall after multiple reflections. Even if light-blocking blades are installed, the light still cannot be cut sharply, resulting in blurred light boundaries and the appearance of ghost images. Summary of the invention

[0004] The invention provides a method and device for drawing a reflective bowl curve, so as to improve the light control effect of the reflective bowl curve.

[0005] In order to solve the above technical problems, an embodiment of the present invention provides a method for drawing a reflective bowl curve, comprising:

[0006] Acquire scene requirements and light source parameters, acquire a plurality of reflective bowl segments based on the scene requirements, and acquire target light intensities corresponding to the reflective bowl segments based on the light source parameters;

[0007] Obtaining a reflection angle range of the reflective bowl segment based on the target light intensity, the light source parameters and a preset light intensity integral equation;

[0008] The respective reflector bowl segment curves are acquired based on the reflection angle range and preset reflector bowl position information, and a target reflector bowl curve is generated based on the reflector bowl segment curves.

[0009] The present invention divides a reflective bowl into a plurality of reflective bowl segments according to scene requirements. Since different reflective bowl segments have different reflection positions and light intensities, the target light intensity of each reflective bowl segment is set by light source parameters, and the light intensity required to be reflected by each light segment is clarified by the target light intensity. The reflection angle range of each segment is determined according to the target light intensity, and the reflective bowl curve of each segment is generated by the reflection angle range, thereby forming a target curve of the entire reflective bowl. By segmenting the reflective bowl according to scene requirements, it is ensured that the light distribution meets the scene design requirements, so as to finely control the reflection path of each segment area, avoid the light intensity concentration problem of the traditional symmetrical reflective bowl, and improve the light control effect of the reflective bowl curve.

[0010] Furthermore, the light source parameters include total light intensity and light distribution curves, and the step of obtaining a plurality of reflective bowl segments based on the scene requirements and obtaining target light intensities corresponding to the reflective bowl segments based on the light source parameters includes:

[0011] Acquire a curtain height and a number of light segments based on the scene requirements, and evenly divide the curtain into a plurality of curtain segments based on the curtain height and the number of light segments;

[0012] A plurality of reflective bowl segments are obtained based on the plurality of curtain segments, and a target light intensity corresponding to each reflective bowl segment is obtained based on the total light intensity and the light distribution curve, wherein the curtain segments correspond to the reflective bowl segments one by one.

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

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

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

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

[0017] The present 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 reflective bowl segment. By performing segmented calculation on the reflective bowl curve, the reflection path of each reflective bowl light segment can be significantly optimized, and the reflection angle range corresponding to each light segment can be accurately determined, ensuring that the light is distributed to a specific area of ​​the curtain according to the design requirements, while improving the uniformity of light distribution and the accuracy of the design.

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

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

[0022] Acquire the height of the reflective bowl based on the reflective bowl position information, and determine the apex of the reflective bowl based on the reflective bowl height;

[0025] A target reflector bowl curve is generated based on the reflector bowl segment curve.

[0026] Since each reflective bowl segment corresponds to a reflection angle range and a light segment endpoint, the present invention accurately calculates the incident light and the reflected light of each reflective bowl segment based on the position information of the reflective bowl, the reflection angle range and the light segment endpoint of the curtain segment, thereby determining the reflective bowl segment curve, and generating an overall target reflective bowl curve based on the reflective bowl segment curves, thereby achieving accurate control of the light reflection path and improving the uniformity of light distribution and the flexibility of design.

[0027] In a second aspect, the present invention provides an asymmetric reflective 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 a number of reflective bowl segments based on the scene requirements, and obtain target light intensities corresponding to the reflective bowl segments based on the light source parameters;

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

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

[0032] Acquire a curtain height and a number of light segments based on the scene requirements, and evenly divide the curtain into a plurality of curtain segments based on the curtain height and the number of light segments;

[0033] A plurality of reflective bowl segments are obtained based on the plurality of curtain segments, and a target light intensity corresponding to each reflective bowl segment is obtained based on the total light intensity and the light distribution curve, wherein the curtain segments correspond to the reflective bowl segments one by one.

[0051] Example 1

[0052] See also Figure 1 , Figure 1The present invention provides a flow chart of a method for drawing an asymmetric reflective bowl curve according to an embodiment of the present invention. The present invention provides a method for drawing an asymmetric reflective bowl curve, including steps 101 to 103, which are as follows:

[0053] Step 101: acquiring scene requirements and light source parameters, acquiring a plurality of reflective bowl segments based on the scene requirements, and acquiring target light intensities corresponding to the reflective bowl segments based on the light source parameters;

[0054] In this embodiment, the light source parameters include total light intensity and light distribution curves, and the steps of obtaining a plurality of reflective bowl segments based on the scene requirements and obtaining target light intensities corresponding to the reflective bowl segments based on the light source parameters include:

[0055] Acquire a curtain height and a number of light segments based on the scene requirements, and evenly divide the curtain into a plurality of curtain segments based on the curtain height and the number of light segments;

[0056] A plurality of reflective bowl segments are obtained based on the plurality of curtain segments, and a target light intensity corresponding to each reflective bowl segment is obtained based on the total light intensity and the light distribution curve, wherein the curtain segments correspond to the reflective bowl segments one by one.

[0057] In the embodiment, the curtain or wall is evenly divided into several sections according to the scene requirements, so as to calculate the light intensity corresponding to each section.

[0058] In this embodiment, the illumination range of the light is determined according to the height of the curtain in the actual scene. The curtain height is an important reference parameter for lighting design. According to the scene requirements (such as lighting uniformity, beam distribution, etc.), it is determined how many segments the curtain is divided into. The more light segments there are, the more refined the lighting distribution is.

[0059] In this embodiment, by clarifying 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 curtain is evenly divided into several segments of equal height according to the curtain height and the number of light segments. Each segment corresponds to a specific lighting area, so that the lighting demand of each segment can be calculated independently, thereby achieving more refined light intensity control.

[0061] In this embodiment, according to the division of the curtain segments, the reflective bowl is also divided into a number of corresponding light segments. Each reflective bowl segment is responsible for reflecting light to the corresponding curtain segment, ensuring that each curtain segment can receive precisely controlled light, and then by combining the total light intensity and the light distribution curve, the target light intensity of each reflective bowl segment can be accurately calculated to ensure that the distribution of light on the curtain meets the design requirements.

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

[0063] In this embodiment, the angular direction of the light source is 0 degrees from the vertical direction, and the angle of the reflected light is calculated as the angle with the horizontal plane.

[0064] In this embodiment, after the wall is divided into X segments based on the scene requirements, the light intensity distribution of the light source can be obtained by combining the light distribution curve and the pre-selection theorem, with the central light intensity being 0° and being cosine distributed, that is:

[0065] I=I0cosθ (1)

[0066] Among them, I is the light intensity at any angle in the direction of the light source, I0 is the light intensity at the center of the light source's direction, and θ is the angle between the light source's direction and the horizontal plane, that is, the reflection angle.

[0067] In this embodiment, according to the cosine distribution, the total light intensity of the light source is I=2I0. If the corresponding light intensity needs to be evenly distributed on the curtain, the target light intensity required for the reflective bowl segment is:

[0068]

[0069] Among them, I X The target light intensity for the reflector bowl segment.

[0070] In this embodiment, the screen height and the number of light segments are determined by 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 demand of each segment can be calculated independently, thereby achieving more refined light intensity control.

[0071] As a specific example in the embodiment of the present invention, the height of the curtain obtained based on the scene requirement is 5M, and the curtain is divided into 10 sections according to the scene requirement, so that the corresponding reflective bowl sections are determined according to the 10 curtain sections, so that the target light intensity corresponding to each reflective bowl section is obtained based on the total light intensity and the light distribution curve.

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

[0073] In this embodiment, after determining the target light intensity, since the positions of each segment in each reflective bowl segment relative to the light source are different, it is necessary to subtract the light intensity directly emitted by the light source from the target light intensity to obtain the light intensity offset, and determine the reflective bowl curve based on the light intensity offset so that the light intensity reflected by the reflective bowl onto each screen plus the light intensity directly emitted by the light source is equal to the target light intensity of each reflective bowl segment.

[0074] In this embodiment, the step of obtaining the reflection angle range of the reflective bowl segment 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 reflective bowl segment based on the target light intensity and the total light intensity;

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

[0077] The present 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 reflective bowl segment. By performing segmented calculation on the reflective bowl curve, the reflection path of each reflective bowl light segment can be significantly optimized, and the reflection angle range corresponding to each light segment can be accurately determined, ensuring that the light is distributed to a specific area of ​​the curtain according to the design requirements, while improving the uniformity of light distribution and the accuracy of the design.

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

[0079]

[0080] Among them, I X is the target light intensity, θ is the reflection angle I0, is the central light intensity in the direction of the light source, ΔI is the light intensity offset, α and β are the curvature coefficients of the reflective bowl, and the curvature coefficients of the reflective bowl are calculated based on the endpoints of the reflective segment and the center of the light source.

[0081] In this embodiment, after the light intensity offset of each reflective bowl segment is obtained, the angle range of each reflective bowl curve is calculated according to the light intensity offset, the central light intensity in the light emitting direction of the light source, and the total light intensity.

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

[0083] In this embodiment, the vertical direction is the curtain, and the curtain is evenly divided into 10 curtain segments, thereby obtaining 10 corresponding reflector segments. Each reflector segment has two endpoints. For the calculation of the reflection angle range of each reflector segment, the angle between the direction of the two endpoints of the reflector segment directly from the center of the light source to the reflector segment and the horizontal plane can be determined based on the endpoint of the reflector segment connecting the center of the light source, and the reflector curvature coefficient is calculated based on the angle. For example, in the second reflector segment, the angle between the direction of the two endpoints of the reflector segment directly from the center of the light source to the horizontal plane is 13 degrees and 11 degrees, respectively, then α is β is According to the light intensity integral equation: Then, the reflection angle range of the second end reflective bowl segment can be obtained by reverse deduction.

[0084] Step 103: acquiring each reflector bowl segment curve based on the reflection angle range and preset reflector bowl position information, and generating a target reflector bowl curve based on the reflector bowl segment curves.

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

[0086] Acquire the height of the reflective bowl based on the reflective bowl position information, and determine the apex of the reflective bowl based on the reflective bowl height;

[0087] Based on the vertex of the reflective bowl, the light segment endpoint of the reflective segment and the reflection angle range, determining the reflective bowl incident light and the reflective bowl reflected light corresponding to the reflective segment;

[0088] Determine a reflective surface based on the incident light of the reflective bowl and the reflected light of the reflective bowl, and generate a reflective bowl segmented curve based on the reflective surface;

[0089] A target reflector bowl curve is generated based on the reflector bowl segment curve.

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

[0091] In this embodiment, the incident light of the reflector bowl is the light incident on the surface of the reflector bowl from the light source or other positions. The reflected light of the reflector bowl is the light reflected from the surface of the reflector bowl. The direction and position of the incident light and the reflected light can be calculated through the vertex of the reflector bowl, the endpoint of the light segment and the reflection angle range. Then, the normal position can be determined according to the direction and position of the incident light and the reflected light. After the position is determined, the reflective surface can be determined, and the reflective bowl segment curve corresponding to each reflective bowl segment is generated based on the reflective surface. Then, the target reflective bowl curve, that is, the overall reflective bowl curve, is drawn and generated according to the reflective bowl segment curves of all reflective bowl segments to ensure that the reflective bowl can reflect light in the expected manner.

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

[0093] In this embodiment, since each reflective bowl segment corresponds to a reflection angle range and a light segment endpoint, the incident light and reflected light of each reflective bowl segment are accurately calculated based on the position information of the reflective bowl, the reflection angle range and the light segment endpoint of the curtain segment, and then the reflective bowl segment curve is determined, and the overall target reflective bowl curve is generated based on the reflective bowl segment curves, thereby achieving precise control of the light reflection path and improving the uniformity of light distribution and design flexibility.

[0094] In this embodiment, the reflective bowl is divided into several reflective bowl segments according to scene requirements. Since different reflective bowl segments have different reflection positions and light intensities, the target light intensity of each reflective bowl segment is set by light source parameters, and the light intensity required to be reflected by each light segment is clarified by the target light intensity. The reflection angle range of each segment is determined according to the target light intensity, and the reflective bowl curve of each segment is generated by the reflection angle range, thereby forming the target curve of the entire reflective bowl. By segmenting the reflective bowl according to scene requirements to ensure that the light distribution meets the scene design requirements, the reflection path of each segment area is finely controlled, the light intensity concentration problem of the traditional symmetrical reflective bowl is avoided, and the light control effect of the reflective bowl curve is improved.
