[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0059] At present, people can only control the stereoscopic light source to light it up or down. For a stereoscopic light source including a color light-emitting unit, they can only further control the corresponding color when it is lit, so that the stereoscopic light source can only be limited to a fixed mode for emitting light, and the luminous effect is single.

[0060] Based on this, an embodiment of the present application proposes a luminous control system for a stereoscopic light source, which aims to generate corresponding control signals according to the light source information of the stereoscopic light source and the luminous effect to be presented, so as to control the stereoscopic light source to emit corresponding light effects, so as to enable the stereoscopic light source to produce a variety of different light effects to meet the needs of rich and varied light effects.

[0061] Embodiment 1

[0062] Reference Figure 1 , Figure 1 Schematic diagram of the structure of the light control system of the stereoscopic light source provided in the first embodiment of the present application. Figure 1 As shown, the light emission control system of the stereoscopic light source includes a stereoscopic light source 1, a driving unit 2 and a main controller 3. The stereoscopic light source 1 includes a plurality of light emitting units 10, the driving unit 2 is electrically connected to each light emitting unit 10, and the main controller 3 is connected to the driving unit 2. The main controller 3 and the driving unit 2 may be electrically connected or may be connected by communication.

[0063] The light-emitting units 10 in the three-dimensional light source 1 can be arranged in different ways, such as linear arrangement, matrix arrangement, circular or ring arrangement, bionic arrangement, random arrangement, etc.

[0064] For example, see Figure 2 and Figure 3 The stereoscopic light source 1 may include a plurality of light panels 11, which are arranged at angles to each other to form light-emitting surfaces at multiple angles, and the multiple light-emitting surfaces are distributed in a three-dimensional space. The stereoscopic light source 1 can reduce its area perpendicular to the irradiation direction, which is conducive to reducing the volume of a high-power stereoscopic light source type movie light 1.

[0065] The light board 11 includes a light-emitting unit 10 and a circuit board 112. The light-emitting unit 10 is arranged on the circuit board 112. The light-emitting unit 10 can be an LED lamp bead, an LED chip, a laser light source, etc. When the light-emitting unit 10 is an LED chip, the LED chip can be directly integrated on the circuit board using the chip on board packaging technology COB (chip on board). Then the light board 11 can also be a COB board. When the light source is lit and emits light, the light source generates heat, and the heat is transferred to the circuit board 112. As an example, the light-emitting unit 10 on the light board 11 includes a plurality of white light LED chips, a plurality of red light LED chips, a plurality of green light LED chips, and a plurality of blue light LED chips, wherein the white light LED chip can be a positive white light LED chip, a warm white light LED chip and / or a cold white light LED chip. The light-emitting unit 10 can also include a yellow light LED chip, a cyan light LED chip, and the like.

[0066] The LED chips are evenly arranged on the circuit board 112, and the arrangement shape of the LED chips corresponds to the shape of the light-emitting surface of the lamp board 11. The arrangement shape of the LED chips can be rectangular, circular, etc. When the density of the LED chips is large, the heat generated by the LED chips is large.

[0067] The light board 11 is also provided with an electrical connection module 113, which can be provided at the outer edge of the circuit board. The circuit of the LED chip on the COB board is integrated in the electrical connection module 113, and the electrical connection module 113 leads outwardly to a cable 114, which can be used to power the light board 11 and transmit data signals.

[0068] The electrical connection modules 113 can be connected to each other through cables 114, and can be electrically connected by plugging. The mutually spliced ​​light panels 11 can be electrically connected and data signal transmitted through the electrical connection module 113. It can be understood that the electrical connection relationship between the light panels 11 can be in series or in parallel. That is, the stereoscopic light source 1 can realize the individual control of the working state of a single light panel 11, and can also realize the simultaneous control of the working state of multiple light panels 11. The working state of the light panel 11 includes lighting, extinguishing, flashing, and the control of LED chips corresponding to different colors to adjust the color temperature.

[0069] The stereoscopic light source 1 may further include a liquid cooling device 20. The stereoscopic light source 1 is disposed on the liquid cooling device 20. Compared with a traditional planar light source, the stereoscopic light source 1 can greatly reduce the projection area of ​​the LED chip on the light emitting surface. In addition, the liquid cooling device 20 can dissipate heat from the stereoscopic light source 1 in a timely manner to ensure high-power light emission.

[0070] The liquid cooling device 20 is in a three-dimensional shape. The liquid cooling device 20 is provided with a plurality of heat-conducting surfaces 201, which are arranged at an angle, and at least two heat-conducting surfaces 201 are equipped with lamp boards 11. Then, the three-dimensional light source 10 can be formed by installing the heat-conducting surfaces 201 of the liquid cooling device 20. Moreover, the lamp board 11 is installed on the heat-conducting surface 201, which can facilitate the heat on the lamp board 11 to be transferred through the heat-conducting surface 201.

[0071] The side of the liquid cooling device 20 can be set as a heat conducting surface 201. Each heat conducting surface 201 corresponds to a light emitting surface. A plurality of light panels 11 can be assembled on the liquid cooling device 20 to form the three-dimensional light source 10. The liquid cooling device 20 can be a cube, a polyhedron, an irregular shape, etc., and the corresponding shape of the three-dimensional light source 10 can also be a cube, a polyhedron, an irregular shape, etc.

[0072] The lamp panels 11 are detachably mounted on the heat conducting surface 201. When one of the lamp panels 11 fails, only the lamp panel 11 needs to be disassembled and replaced, while the other lamp panels 11 can continue to work normally, thus facilitating maintenance and saving maintenance costs.

[0073] See also Figure 3 The liquid cooling device 20 includes a liquid cooling box 21. The liquid cooling box 21 is provided with at least one liquid cooling chamber for circulating cooling liquid. The liquid cooling box 21 is also provided with a liquid inlet and a liquid outlet connected to the liquid cooling chamber. The cooling liquid enters the liquid cooling chamber through the liquid inlet and is discharged from the liquid outlet. The flowing cooling liquid flows out of the liquid cooling chamber and can take away the heat on the heat conducting surface 201, thereby realizing heat dissipation of the lamp board 11.

[0074] The liquid cooling box 21 has six side surfaces. Five of the side surfaces can be used as heat-conducting surfaces 201, and the other side surface can be provided with a liquid inlet 212 and a liquid outlet 213, and is used to lead out the liquid inlet pipe 63, the liquid outlet pipe 64, the cable 114 and other lines. Alternatively, the side surface can also be used for assembly to fix the liquid cooling box 21 on an external bracket. Alternatively, the side surface can also be provided with a snap-fit ​​structure to enable the liquid cooling boxes 21 to be spliced ​​with each other. Alternatively, when the liquid inlet pipe 63, the liquid outlet pipe 64 and the cable 114 do not interfere with the operation of other lamp boards 11, the side surface can also be used as a heat-conducting surface 201 for installing the lamp board 11, thereby increasing the number of lamp boards 11 installed in the liquid cooling box 21.

[0075] Reference Figure 2The stereoscopic light source 1 may further include an external liquid cooling box 60 and a power control device 70. The liquid cooling box 60 is independent of the liquid cooling device 20. Moreover, the liquid cooling box 60 and the liquid cooling device 20 are connected to each other. The liquid cooling box 60 provides low-temperature cooling liquid for the liquid cooling device 20. The cooling liquid may be low-temperature water, low-temperature fluorinated liquid, low-temperature silicone oil, etc. The liquid cooling box 60 is independently arranged from the liquid cooling device 20, does not occupy the space of the liquid cooling device 20, and does not increase the weight of the liquid cooling device 20, which can facilitate the layout of the stereoscopic light source 10. Moreover, the distance between the liquid cooling box 60 and the liquid cooling device 20 can be adjusted according to the use requirements, and can be suitable for a variety of occasions.

[0076] The power control device 70 is used for connecting an external power source. The power control device 70 is electrically connected to the light board 11 and the liquid cooling box 60 , and is used for supplying power to the light board 11 and the liquid cooling box 60 .

[0077] The power control device 70 can be directly electrically connected to the cable 114 of the light board 11. The light boards 11 can be connected in series or in parallel. Alternatively, the power control device 70 is provided with a wire 31, and the power control device 70 is electrically connected to the stereoscopic light source type movie light 1 through the wire 71. The power control device 70 is connected to the light board 11 by electrical signals. The power control device 70 can realize the control of various working states of the light board 11.

[0078] The power control device 70 can also be electrically connected to the liquid cooling box 60 of the liquid cooling device to supply power to the liquid cooling box 60. The power control device 70 can also be electrically connected to the liquid cooling box 60. After the power control device 70 controls the liquid cooling box 60 to start working, it controls the light board 11 to be powered on. Thus, the operation of the liquid cooling box 60 is controlled. The power control device 70 is provided with a wire 72, and the power control device 70 is electrically connected to the liquid cooling box 60 through the wire 72.

[0079] The driving unit 2 may include a driving circuit, and may also include a microprocessor and a control circuit to drive and control the light emitting unit 10 connected thereto.

[0080] The main controller 3 is connected to the driving unit 2 to send the generated control signal to the driving unit 2, so that the driving unit 2 drives and controls the corresponding light-emitting unit 10 according to the received control signal.

[0081] In the embodiment of the present application, a driving unit 2 is provided to be connected to all the light-emitting units 10, and a main controller 3 is provided to be connected to the driving unit 2, so that the brightness, color, switch state, etc. of all the light-emitting units 10 can be uniformly managed by a main controller 3 to achieve different lighting effects. In this case, a corresponding graphical interface can be provided, and the user can adjust the relevant parameters of each light-emitting unit 10 through a computer or a dedicated control device.

[0082] Embodiment 2

[0083] Reference Figure 4 , Figure 4 Schematic diagram of the structure of the light control system of the stereoscopic light source provided in the second embodiment of the present application. Figure 4 As shown, the light emission control system of the stereoscopic light source includes a stereoscopic light source 1, a plurality of driving units 2 and a main controller 3. The stereoscopic light source 1 includes a plurality of light emitting units 10, the driving units 2 are electrically connected to the corresponding plurality of light emitting units 10, and the main controller 3 is connected to each driving unit 2. The main controller 3 and each driving unit 2 may be electrically connected or may be connected by communication.

[0084] In the embodiment of the present application, a plurality of light-emitting units 10 may be grouped in advance according to the arrangement of the light-emitting units 10, such as axial grouping, circumferential grouping, and planar grouping based on the arrangement of the light-emitting units 10. For example, a plurality of light-emitting units 10 arranged and formed on the same light-emitting surface may be regarded as a group, or a plurality of light-emitting units 10 arranged axially may be regarded as a group, or a plurality of light-emitting units 10 arranged circumferentially may be regarded as a group. A plurality of light-emitting units 10 in the same group are electrically connected to a driving unit 2, and each group of light-emitting units is electrically connected to a corresponding driving unit 2, so that a driving unit 2 can simultaneously control each light-emitting unit 10 in a group to emit light. In other words, a plurality of light-emitting units 10 in a group are driven by a driving unit 2. Among them, each light-emitting unit 10 in a group may be connected in series, in parallel, or in mixed series.

[0085] In the embodiment of the present application, the main controller 3 is connected to each driving unit 2 to send the generated control signal to the corresponding driving unit 2, so that the corresponding driving unit 2 can drive and control the corresponding light-emitting unit 10 according to the received control signal.

[0086] In the embodiment of the present application, a driving unit 2 is provided to be connected to a corresponding plurality of light-emitting units 10, and a main controller 3 is provided to be connected to each driving unit 2, so that each driving unit 2 can perform driving control on each light-emitting unit 10 to achieve different lighting effects.

[0087] It should be noted that the stereoscopic light source 1 in the embodiment of the present application is the same as the stereoscopic light source described in the first embodiment, and will not be described in detail here.

[0088] For example, refer to Figure 5 , Figure 5 is an example diagram of a stereoscopic light source provided by an embodiment of the present application. Figure 5As shown, the stereoscopic light source 1 includes a plurality of lamp panels 11, which are arranged circumferentially inside the cooling base 14. A reflective cup is provided at the center of the cooling base 14. The reflective cup is used to concentrate and reflect the light emitted by each lamp panel 11 to a specific direction, thereby improving the lighting efficiency and the intensity of the light beam. Taking the lamp panels 11 arranged circumferentially in two circles inside the cooling base 14, each lamp panel 11 is an RGBW LED as an example, each lamp panel 11 includes a red LED, a green LED, a blue LED and a white LED. The red LEDs in each lamp panel 11 in the inner circle are taken as a group, the green LEDs in each lamp panel 11 in the inner circle are taken as a group, the blue LEDs in each lamp panel 11 in the inner circle are taken as a group, and the white LEDs in each lamp panel 11 in the inner circle are taken as a group. The red LEDs in each lamp panel 11 in the outer circle are taken as a group, the green LEDs in each lamp panel 11 in the outer circle are taken as a group, the blue LEDs in each lamp panel 11 in the outer circle are taken as a group, and the white LEDs in each lamp panel 11 in the outer circle are taken as a group. The light-emitting units can be divided into 8 groups, each of which is driven by a corresponding driving unit 2, that is, there are 8 driving units 2. Among them, the same color LEDs are connected in series. The main controller 3 can generate corresponding control signals and output the control signals to each driving unit 2 to control the luminous brightness and switching state of each light-emitting unit 10. For example, when all the light-emitting units 10 in the two circles of light boards 11 are controlled to light up at the same time, a relatively large irradiation range can be obtained (the divergence angle of the light emitted by the light board is larger). When only the light boards 11 in the inner circle are controlled to light up, the light concentration range is smaller (the divergence angle is small), which can produce an effect similar to focusing. That is, the focusing effect can be achieved only by circuit control without configuring structures such as focusing mirrors. In addition, by adjusting the ratio of the duty cycle of the drive signal of each driving unit 2, the adjustment of different color temperatures can be achieved.

[0089] It should be noted that the number of circles of the light panels 11 can be greater than 2, for example, 3 circles, 4 circles, or 5 circles. Each circle of light panels 11 can achieve control of different color temperatures, thereby forming an illumination effect similar to colorful concentric apertures within the illumination range, achieving more personalized lighting effects. Since each light panel 11 contains a large number of multi-color light-emitting chips, the light color rendering index formed after mixing is high, and the luminous power and controllable brightness level of the stereoscopic light source can increase exponentially under the same projection area.

[0090] On this basis, further adding timing control can also achieve more dynamic light effects. For example, the red LEDs corresponding to the light boards 11 in the inner circle can be controlled to light up, while the LEDs of other colors corresponding to the light boards 11 in the inner circle can not light up, and the green LEDs corresponding to the light boards 11 in the outer circle can be controlled to light up, while the LEDs of other colors corresponding to the light boards 11 in the outer circle can not light up, that is, the inner circle can be controlled to light up red, while the outer circle can be controlled to light up green. Then the inner circle can be controlled to light up green, while the outer circle can be controlled to light up blue; then the inner circle can be controlled to light up blue, while the outer circle can be controlled to light up red, so as to achieve a light effect with dynamic changes in luminous colors.

Figure 6 As shown, the light control system of the stereoscopic light source includes a stereoscopic light source 1, a plurality of driving units 2 and a main controller 3. The stereoscopic light source 1 includes a plurality of light-emitting units 10. The number of driving units 2 is the same as the number of light-emitting units 10, and each light-emitting unit 10 is electrically connected to a corresponding driving unit 2, and the main controller 3 is connected to each driving unit 2. The main controller 3 and each driving unit 2 may be electrically connected or communicated.

[0093] In the embodiment of the present application, each light-emitting unit 10 is electrically connected to a corresponding driving unit 2 , so that each light-emitting unit 10 can be individually controlled.

[0096] In the embodiment of the present application, the lighting effect that needs to be presented by the stereoscopic light source 1 is first determined. For example, a lower intensity lighting effect can be used in a lyrical scene, a high intensity lighting effect can be used in a passionate scene, a warm yellow lighting effect can be selected to create a warm family atmosphere, and a blue lighting effect can be selected to create a sense of technology.

[0097] Specifically, in some embodiments, the lighting effect to be presented can be determined by analyzing the text description of the user's lighting effect requirements, that is, the user can customize the lighting effect that the stereoscopic light source 1 needs to present according to personal preferences and on-site environment.

[0098] In some embodiments, the current environment conditions can also be obtained, and the luminous effect to be presented can be determined according to the current environment conditions, wherein the luminous effect to be presented matches the current environment. That is, the main controller 3 can identify the current environment conditions to determine the luminous effect that matches the current environment. For example, to match the tense and active atmosphere created on the scene, it can be determined that the stereoscopic light source 1 needs to present a high-frequency flickering luminous effect. To match the soothing and mysterious atmosphere created on the scene, it can be determined that the stereoscopic light source 1 needs to present a low-frequency flickering luminous effect. Or to match the dynamic sound effects played on the scene, it can be determined that the stereoscopic light source 1 needs to emit a high-frequency flickering light effect, and to match the sad sound effects played on the scene, it can be determined that the stereoscopic light source 1 needs to emit a soft light effect.

[0099] Step S720, obtaining light source information of the stereoscopic light source, where the light source information includes an arrangement of light emitting units, a driving method of the light emitting units, and a type of each light emitting unit.

[0100] In the embodiment of the present application, considering that the arrangement of the light-emitting units 10 is different, the corresponding luminous effects that can be presented are different, and the types of the light-emitting units 10 are different, the corresponding luminous effects are also different. That is, the luminous effect is related to the arrangement and type of the light-emitting units 10 in the stereoscopic light source 1. For example, if it is necessary to present luminous effects of different colors, the type of the light-emitting units 10 needs to be lamp beads that can emit different colors. If it is necessary to present a circular luminous effect, the light-emitting units 10 need to be arranged in a circle. In addition, how to control each light-emitting unit 10 to emit light to present the corresponding luminous effect is also related to the driving mode of the light-emitting unit 10. For example, for the driving mode in which each light-emitting unit 10 is driven separately, a richer luminous effect can be achieved, while for the driving mode in which multiple light-emitting units 10 are driven by one driving unit 2, the luminous effect that can be presented is relatively limited. Therefore, in order to control the stereoscopic light source 1 to emit different luminous effects, the embodiment of the present application needs to first obtain the light source information of the stereoscopic light source 1, wherein the light source information includes the arrangement mode of the light-emitting units 10, the driving mode of the light-emitting units 10, and the type of each light-emitting unit 10. Among them, the type of the light-emitting unit 10 can be directly obtained through the product description of the stereoscopic light source 1, the arrangement of the light-emitting unit 10 can be obtained through the structure of the stereoscopic light source 1, and the driving method of the light-emitting unit 10 can be obtained by analyzing the driving circuit of the stereoscopic light source 1.

[0101] Step S730: Generate a control signal according to the lighting effect to be presented and the light source information.

[0102] In the embodiment of the present application, after determining the lighting effect to be presented and the light source information of the stereoscopic light source 1, the main controller 3 can generate a control signal according to the lighting effect to be presented and the light source information. Among them, the control signal can be a driving signal (i.e., a control instruction) or a sequence of driving signals (i.e., multiple control instructions). For example, for a simple lighting effect, it can be achieved by sending a corresponding control instruction to the corresponding driving unit 2. For dynamic or complex lighting effects, it is necessary to send multiple control instructions to the corresponding driving unit 2 to achieve it.

[0103] It should be noted that for complex dynamic light effects, the light emission of each light emitting unit 10 can be controlled by writing a program. The program can be run on the main controller 3 or on the microprocessor of each driving unit 2. For simple light effects, it can be realized by a control circuit.

[0104] Reference Figure 8 , Figure 8 It is a first step flowchart of generating a control signal according to the lighting effect to be presented and the light source information provided by an embodiment of the present application, including but not limited to steps S810 to S820.

[0105] Step S810, determining the lighting order and lighting time interval of each lighting unit according to the lighting effect to be presented and the arrangement of the lighting units;

[0106] Step S820, generating control signals corresponding to the respective driving units according to the light-emitting sequence and light-emitting time interval of the respective light-emitting units and the driving mode of the respective light-emitting units, wherein the control signals include timing control signals.

[0107] In the embodiment of the present application, the light-emitting sequence and the time interval of each light-emitting unit 10 can be determined according to the light-emitting effect to be presented and the arrangement of the light-emitting units 10, so that the control signals corresponding to each driving unit 2 can be generated according to the light-emitting sequence and the time interval of each light-emitting unit 10 and the driving mode of each light-emitting unit 10, and the control signal includes a timing control signal. For example, if the light-emitting effect to be presented is the light-emitting effect of flowing light, and the arrangement mode of the light-emitting units 10 is a linear arrangement, a dynamic light-emitting effect can be created by controlling the light-emitting sequence and time interval of each light-emitting unit 10. Here, if each light-emitting unit 10 is driven separately, the light effect of the light-emitting units 10 lighting up in sequence can be achieved by timing control. For example, in some light strips (stereoscopic light sources) for architectural decoration, each light-emitting unit 10 is arranged linearly, and by controlling each light-emitting unit 10 to light up in sequence according to a certain order and interval, a flowing light effect can be formed, flowing along the light strip like flowing water. Among them, the spacing between the light-emitting units 10 is small, and the light will look more uniform. For another example, if the arrangement of the light-emitting units 10 is a bionic arrangement, and the light-emitting effect to be presented is a light-emitting effect that imitates biological luminescence, a dynamic light-emitting effect can also be created by controlling the light-emitting sequence and time interval of each light-emitting unit 10. For example, to imitate the light-emitting effect of fireflies, the light-emitting sequence and time interval of each light-emitting unit 10 can be determined according to the characteristics of the light-emitting of fireflies, and the control signals corresponding to each driving unit 2 are generated according to the light-emitting sequence and time interval of each light-emitting unit 10 and the driving mode of each light-emitting unit 10, so that the three-dimensional light source 1 can be controlled to emit light according to the flashing law and rhythm of fireflies.

[0108] Reference Fig. 9 , Fig. 9 It is a second step flowchart of generating a control signal according to the lighting effect to be presented and the light source information provided by an embodiment of the present application, including but not limited to steps S910 to S920.

[0109] Step S910, determining the lighting state of each lighting unit according to the lighting effect to be presented and the type of each lighting unit, the lighting state including on or off, lighting color or lighting brightness;

[0110] Step S920, generating control signals corresponding to the respective driving units according to the light-emitting states of the respective light-emitting units and the driving modes corresponding to the respective light-emitting units, wherein the control signals include light-emitting state control signals.

[0111] In the embodiment of the present application, the luminous state of each luminous unit 10 can also be determined according to the luminous effect to be presented and the type of each luminous unit 10, wherein the luminous state includes on or off, luminous color or luminous brightness. Thus, according to the luminous state of each luminous unit 10 and the driving mode corresponding to each luminous unit 10, the control signal corresponding to each driving unit 2 can be generated, and the control signal includes a luminous state control signal. Exemplarily, if the luminous effect to be presented is a blue light effect, the luminous type of the luminous unit 10 is a colored lamp bead that can emit multiple colors (including blue). If the driving mode of the luminous unit 10 is that all blue lamp beads are driven by one driving unit B, then the luminous state control signal corresponding to each driving unit 2 can be generated accordingly, so that the driving unit B can control all blue lamp beads to light up based on the corresponding luminous state control signal, and other driving units 2 can control the lamp beads of other colors not to light up based on the corresponding luminous state control signal. For another example, if the light-emitting effect to be presented is a star-like twinkling light effect, the light-emitting type of the light-emitting unit 10 is a monochrome lamp bead, and each light-emitting unit 10 can be randomly arranged. At this time, if the driving mode of each light-emitting unit 10 is individual driving, then according to the light-emitting state of each light-emitting unit 10 (some lamp beads emit stronger light, and the other part emits weaker light) and the corresponding driving mode of each light-emitting unit 10, a control signal corresponding to each driving unit 2 is generated, and the three-dimensional light source 1 can be controlled to present a star-like twinkling light effect.

[0112] Reference Fig.10 , Fig.10 It is a flowchart of the third step of generating a control signal according to the lighting effect to be presented and the light source information provided by an embodiment of the present application, including but not limited to steps S1010 to S1020.

[0113] Step S1010, determining the brightness difference between the light-emitting units at different positions according to the light-emitting effect to be presented and the arrangement of the light-emitting units;

[0114] Step S1020, generating control signals corresponding to the respective driving units according to the brightness difference between the light-emitting units at different positions and the driving modes corresponding to the light-emitting units, wherein the control signals include light-emitting brightness control signals.

[0115] In the embodiment of the present application, the brightness difference between the light-emitting units 10 at different positions can also be determined according to the light-emitting effect to be presented and the arrangement mode of the light-emitting units 10, so as to generate control signals corresponding to each driving unit 2 according to the brightness difference between the light-emitting units 10 at different positions and the driving mode corresponding to each light-emitting unit 10, and the control signal includes a light-emitting brightness control signal. Exemplarily, the arrangement mode of the light-emitting units 10 is a ring arrangement, and the light-emitting effect to be presented is a concave or convex visual effect. It can be determined that the light-emitting units 10 in the middle part of the ring have a higher brightness, and the light-emitting units 10 in the surrounding part gradually reduce the brightness, so as to give people a concave or convex visual effect and enhance the three-dimensional layering. That is, according to the brightness difference between the light-emitting units 10 at different positions and the driving mode corresponding to each light-emitting unit 10, the light-emitting brightness control signals corresponding to each driving unit 2 are generated, so that each driving unit 2 controls the corresponding light-emitting unit 10 to emit light of the corresponding target brightness according to the corresponding light-emitting brightness control signal to achieve a concave or convex visual effect.

[0116] It should be noted that when a complex and dynamically changing light effect needs to be presented, the light information corresponding to each light emitting unit 10 can be determined according to the light effect to be presented, the arrangement of the light emitting units 10, and the type of each light emitting unit 10. The light emitting information includes the light emitting sequence, light emitting time interval, light emitting state, and light emitting brightness. Then, according to the light emitting information of each light emitting unit 10 and the driving mode corresponding to each light emitting unit 10, the control signal corresponding to each driving unit is generated.

[0117] Step S740: sending the control signal to the driving unit, so that the driving unit controls the corresponding light-emitting unit to emit light according to the control signal and mixes the light to present a light-emitting effect.

[0118] In the embodiment of the present application, after generating control signals corresponding to each driving unit 2, the main controller 3 can send the corresponding control signals to the corresponding driving unit 2, so that the corresponding driving unit 2 controls the corresponding light-emitting unit 10 to emit light according to the corresponding control signals, so that the stereoscopic light source 1 can emit corresponding light effects. In this way, the stereoscopic light source 1 can be controlled to produce different light effects to meet the needs of rich and varied light effects.

[0119] Reference Fig.11 , Fig.11 It is a flowchart of the second step of the light emission control method of the stereoscopic light source provided in one embodiment of the present application, which is executed by the main controller 3 described in any embodiment of the present application, including but not limited to steps S1110 to S1130.

[0120] Step S1110, calculating the brightness of light-emitting units at different positions under different zoom states according to the arrangement of the light-emitting units;

[0121] Step S1120, generating control signals corresponding to the respective driving units according to the brightness of the light-emitting units at different positions in different zoom states and the driving modes corresponding to the light-emitting units, wherein the control signals include light-emitting brightness control signals;

[0122] Step S1130, sending the control signal to the driving unit, so that the driving unit controls the corresponding light-emitting unit to emit light according to the control signal, so as to achieve a light-controlled zoom effect.

[0123] In the embodiment of the present application, the main controller 3 can calculate the brightness of the light-emitting units 10 at different positions under different zoom states according to the arrangement of the light-emitting units 10, that is, determine the corresponding relationship between the brightness of the light-emitting units 10 at different positions and the irradiation range. Then, according to the brightness of the light-emitting units 10 at different positions under different zoom states and the driving modes corresponding to each light-emitting unit 10, the light-emitting brightness control signals corresponding to each driving unit 2 are generated, that is, according to the corresponding relationship between the brightness of the light-emitting units at different positions and the irradiation range and the driving modes corresponding to each light-emitting unit, the light-emitting brightness control signals corresponding to each driving unit 2 are generated. Then, each control signal is sent to the corresponding driving unit 2, so that the corresponding driving unit 2 can control the corresponding light-emitting unit according to the control signal to achieve the light-controlled zoom effect. For example, by adjusting the brightness of the light-emitting units close to the center to increase and the brightness of the light-emitting units at the edge to decrease, the stereoscopic light source can be made to look more concentrated, thereby achieving the effect of "focusing". In this regard, the brightness of different light-emitting units 10 under different zoom states is calculated by an algorithm, and then adjusted in real time, so as to achieve a smooth light-controlled zoom effect. For example, through the generated control signal, the illumination range of the stereoscopic light source 1 can be zoomed from large to medium and then to small.

[0124] It should be noted that, in the embodiment of the present application, the range of the luminous brightness can be from 0 to the upper limit of the luminous brightness. When the luminous brightness is 0, it indicates that the corresponding light-emitting unit 10 is not bright.

[0125] It should be noted that in the embodiment of the present application, the control of the light-emitting parameters (such as light-emitting state, light-emitting brightness, light-emitting color, etc.) of the light-emitting unit can be achieved by adjusting the current, voltage or PWM duty cycle.
