[0002] With the rapid development of technology, the computing performance of processors has increased significantly, but this also generates a large amount of heat. To ensure that the processor is not damaged by high heat, fans must be installed on electronic products to dissipate excess heat from the processor, allowing the processor to operate within a certain operating temperature range.

[0003] In addition to focusing on the existing heat dissipation function, manufacturers of fans are now also beginning to pay attention to the aesthetics of the fan during operation. Generally speaking, manufacturers will set up multiple light-emitting diodes and multiple light-guiding elements in the fan to emit light on each side of the fan through these light-emitting diodes and these light-guiding elements, so that the fan produces a cool visual effect when it is running. However, the light is currently mainly set on the fan frame, especially when it is in the double halo form, which increases the difficulty of making the fan frame and its shape and size. In addition, when assembling the light-emitting fan, multiple additional fixings are usually required for fixing, making the assembly steps too cumbersome and time-consuming. In addition, the lights of existing cooling fans can only serve a simple decorative effect and cannot be changed or serve other purposes. Summary of the Invention

[0022] The technical solutions in the embodiments of the invention will be described clearly and completely below with reference to the drawings in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all the embodiments.

[0023] refer to Figure 1-2 , a cooling fan with a double halo, comprising a fan frame 1 and a fan blade 2 installed therein, and also comprising a motor 3 for driving the fan blade 2 to rotate, a accommodating space 11 is provided in the fan frame 1, a convex sleeve 12 is provided in the accommodating space 11, the fan blade 2 comprises a light-transmitting central axis portion 21, in this embodiment, the central axis portion 21 is a transparent object made of plastic material, and one side of the central axis portion 21 is provided with a convex boss 211, and the other side is provided with a concave central hole 212 for sleeve-fitting the sleeve 12, the fan blade 2 is further provided with an annular groove 213 surrounding the outer ring of the central hole 212, and the fan blade 2 is installed in the accommodating space 11, the motor 3 is installed outside the sleeve 12 and placed in the central hole 212, the motor 3 A main board 4 and a sub-board 5 are provided on both sides respectively, so that in this embodiment, the motor 3, the main board 4 and the sub-board 5 are connected together to form an integrated installation module. It should be noted that the main board 4 is at the root of the sleeve 12 and supplies power to the motor 3 and the sub-board 5. The motor 3 is connected to the main board 4 through the corresponding legs and forms electrical conduction, and the main board 4 also leads out the corresponding pins to graft the sub-board 5 and form electrical conduction, so as to realize the connection of the motor 3, the main board 4 and the sub-board 5 into an integrated installation module, and the motor 3, the main board 4 and the sub-board 5 have through holes that match the sleeve 12, so that they can be fitted with the middle hole 212 on the sleeve 12. This method is easy to install and uses the sleeve 12 for positioning, making the installation stable and accurate.

[0024] Specifically, the main board 4 is provided with a first light-emitting element 61, and the position of the first light-emitting element 61 corresponds to the annular groove 213 to form a first halo. Specifically, when the first light-emitting element 61 is lit, the light emitted by the first light-emitting element 61 will be injected into the annular groove 213 and guided out from the central axis 21 to form a first halo. The sub-board 5 is located in the middle hole 212 and is provided with a second light-emitting element 62, and its position corresponds to the boss 211 to form a second halo. Specifically, after the sub-board 5 sinks to the inner bottom of the middle hole 212, the second light-emitting element 62 is lit, and the light emitted by the second light-emitting element 62 is injected into the boss 211 and guided out from the boss 211 to form a second halo, so that the first halo and the second halo form a double halo setting, thereby producing a cool visual effect when the fan is running.

[0025] It should be noted that, in this embodiment, the fan blades 2 also include a plurality of blades 22 extending outward from the outer ring of the central axis 21 and distributed at equal intervals. The blades 22 are fixed on the outer ring of the annular groove 213. The central hole 212 and the annular groove 213 are coaxially arranged. A rotating shaft 214 located at the center of symmetry is provided in the central hole 212. The annular groove 213 is mounted on the sleeve 12 through a bearing 215. The inner wall of the central hole 212 is provided with an annular rubber magnet 216, which cooperates with the motor 3. It should be noted that, in this embodiment, the motor 3 in the figure is marked with a stator core and a coil. During operation, the motor 3 cooperates with the annular rubber magnet 216 to realize that the coil of the motor 3 is energized to generate a magnetic field, and the magnetic field acts on the annular rubber magnet 216, thereby driving the fan blades 2 to rotate, thereby achieving heat dissipation.

[0026] It should also be noted that if Figure 2 As shown, the boss 211 and the middle hole 212 are coaxially arranged, and the boss 211 protrudes from the front of the middle axis 21. The diameter of the boss 211 is smaller than the diameter of the middle hole 212, which makes the whole more layered and is conducive to forming a double halo luminous effect.

[0027] Secondly, it should be noted that, in this embodiment, the first light emitting element 61 and the second light emitting element 62 are both LED lamp beads, which makes it easy to manufacture and assemble. The first light emitting element 61 is front-emitting, and the second light emitting element 62 is side-emitting. Figure 2 As shown, the first light-emitting element 61 is facing the notch of the annular groove 213, the middle hole 212 extends into the boss 211, and the second light-emitting element 62 is located in the extension of the middle hole 212, so that the light emitted by 6161 enters the annular groove 213 and is guided out from the inner bottom of the annular groove 213 to form a first halo. The first halo is located on the front of the central axis 21, and the light emitted by the second light-emitting element 62 is emitted toward the peripheral side of the boss 211, so that a second halo is formed on the peripheral side of the boss 211. The two double haloes are staggered to obtain a cool visual effect on the fan blades.

[0028] The present invention forms a double halo on the fan blade 2 by designing the structure of the fan blade 2 and matching different light-emitting elements, so as to produce a cool visual effect when the fan is running. At the same time, the structure of the fan frame 1 will not be increased, and the main board 4 and the sub-board 5 can be installed and positioned by installing the motor 3, without the need for additional fixings for assembly. Therefore, the overly complicated assembly steps of the light-emitting fan can be simplified, making it easier to manufacture and assemble.

[0029] See Figure 3 FIG. 1 is a flow chart of a method for controlling light of a cooling fan with dual light rings according to an embodiment of the present invention, including:

[0030] S1. Query the light-emitting elements of the cooling fan, where the light-emitting elements include a first light-emitting element and a second light-emitting element, wherein the first light-emitting element emits light from the front and the second light-emitting element emits light from the side.

[0031] By querying the light-emitting elements of the cooling fan, the present invention can clearly understand the lighting configuration of the fan and clarify the type of light-emitting elements, which helps to adjust the use of the fan according to actual needs to achieve the best lighting effect, thereby ensuring that the normal use and lighting function of the fan are not affected.

[0032] The light-emitting element refers to a component installed in the cooling fan for producing a light effect, specifically a first light-emitting element (61) and a second light-emitting element (62), which are usually LED lamp beads, playing the role of lighting and creating special light effects in the fan. Different positions and light-emitting characteristics of the light-emitting elements form different halo effects, such as the first light-emitting element (61) and the ring groove (213) form a first halo, and the second light-emitting element (62) and the boss (211) form a second halo.

[0033] Specifically, the light-emitting element includes a first light-emitting element and a second light-emitting element. The first light-emitting element is front-emitting, and the second light-emitting element is side-emitting. The front-emitting element means that the first light-emitting element can provide direct, bright, and relatively uniform light, fully illuminating the entire front area of the fan, enhancing the overall visual brightness and transparency. For example, in a dark environment, the outline and presence of the fan can be clearly displayed. The side-emitting element means that the second light-emitting element can create a unique atmosphere and sense of layering. It can project light from the side, forming a unique light and shadow effect, increasing the three-dimensional sense and depth of the light. For example, inside a computer case, the side light of the second light-emitting element can illuminate the space around the fan.

[0034] S2. In response to the light control voice of the cooling fan, analyzing the light control signal in the cooling fan by the light control voice, and determining the controlled light emitting element corresponding to the light control signal from the light emitting elements;

[0035] The present invention greatly improves the convenience of user operation by responding to the light control voice of the cooling fan, enhances the interactive experience between the user and the device, makes the operation of the device more natural and intuitive, and can obtain the ideal lighting environment in time.

[0036] Among them, the lighting control voice refers to specific voice commands issued to control the lighting effects of the cooling fan. These commands may include various lighting-related operation requirements, such as "turn on the light", "turn off the light", "brighten the light", "dim the light", "switch the light color", "set the light flashing mode", etc. Optionally, the lighting control voice in response to the cooling fan can be implemented through intelligent voice tools, such as Alexa, Assistant and other tools.

[0037] The present invention provides a basis for further optimizing and expanding the control function of the fan light by parsing the light control voice in the cooling fan, facilitating the subsequent addition of more complex and innovative control instructions, effectively avoiding misoperation and misunderstanding, and making the control of the fan light more reliable and stable.

[0038] The lighting control signal refers to a specific electrical signal ultimately used to control the lighting of the cooling fan, which can directly act on the lighting system of the fan to achieve corresponding lighting effect changes.

[0039] As an embodiment of the present invention, parsing the light control signal of the light control voice in the cooling fan includes: performing voice preprocessing on the light control voice to obtain a preprocessed control voice; extracting voice features and control features from the preprocessed control voice, and calculating a feature connection degree between the voice features and the control features using the following formula:

[0040]

[0041] Wherein, TL represents the feature connection degree between the speech feature and the control feature, i represents the feature index corresponding to the speech feature and the control feature, n represents the total number of features corresponding to the speech feature and the control feature, fv i represents the value of the i-th speech feature, Represents the mean of speech features, Cz i represents the value of the i-th control feature, represents the mean of the control characteristic;

[0042] Perform semantic analysis on the feature connection degree to obtain speech analysis parameters; generate control instructions corresponding to the cooling fan based on the speech analysis parameters; and analyze the lighting control signal corresponding to the control instruction.

[0043] The preprocessed control speech refers to the speech data obtained after preliminary processing and optimization of the original lighting control speech, for example, after noise removal, audio enhancement, segmentation, and other operations. The speech features refer to parameters or attributes extracted from the preprocessed control speech that reflect the essential characteristics of the speech, such as the frequency, amplitude, duration, and intonation of the speech. The control features refer to features related to specific lighting control operations, such as features that indicate control intent such as light brightness adjustment, color switching, and flashing mode. The feature connectivity is a numerical value used to measure the degree of correlation between speech features and control features. It reflects the close relationship between the two in expressing and conveying control information. The speech analysis parameters are parameters obtained through semantic analysis of the feature connectivity, which are used to further understand and process the speech control intent. The control instructions are instructions generated based on the speech analysis parameters that clearly define specific control actions and requirements, such as "brighten the lights to 50% brightness."

[0044] Furthermore, the speech preprocessing of the light control voice can be achieved through preprocessing methods, such as noise removal, speech enhancement and other methods; the extraction of speech features and control features in the preprocessed control voice can be achieved through feature extraction methods, such as time domain feature extraction, frequency domain feature extraction, cepstrum feature extraction and other methods; the semantic analysis of the feature connectivity can be achieved through semantic analysis tools, such as Stanford CoreNLP, LTP and other tools; the generation of the control instructions corresponding to the cooling fan can be achieved through Python's rule engine library, such as pyke and the like; the analysis of the light control signal corresponding to the control instruction can be achieved through analysis tools, such as oscilloscopes, logic analyzers and other tools.

[0045] The present invention can achieve precise control of the lighting effect by clarifying the controlled light-emitting element corresponding to the light control signal from the light-emitting element, avoiding confusion or disharmony of the overall lighting effect, thereby reducing energy consumption and extending the service life of the equipment.

[0046] Wherein, the control light emitting element refers to a light emitting element that is determined to be required to perform a specific operation (such as brightness adjustment, color switching, flicker control, etc.) according to the received light control signal. For example, in a cooling fan with a double halo, the first light emitting element (61) and the second light emitting element (62) may be respectively identified as control light emitting elements under different control instructions. If the control instruction is to enhance the light effect of the side, then the second light emitting element (62) is identified as the control light emitting element; if the control instruction is to brighten the light of the entire front, then the first light emitting element (61) becomes the control light emitting element. Optionally, the control light emitting element corresponding to the light control signal can be realized by a microcontroller, such as Arduino, STM32 and other tools.

[0047] S3, mining the lighting influence factor of the controlled light-emitting element, and calculating the luminous brightness of the controlled light-emitting element based on the lighting influence factor;

[0048] The present invention contributes to more accurate and optimized lighting control by exploring the lighting influencing factors of the light-emitting elements, and can make extremely detailed adjustments to the lighting effects according to different usage scenarios and requirements to achieve the best visual effects and functional requirements.

[0049] Among them, the lighting influence factor refers to various factors that can affect the luminous effect of the light-emitting element, for example, the input power of the light-emitting element, which directly determines the amount of energy the element can obtain, thereby affecting the brightness of the light; the luminous efficiency, which reflects the ability of the element to convert electrical energy into light energy, and the efficiency will change the final luminous effect; the environmental sensitivity coefficient, changes in environmental conditions such as temperature and humidity may affect the performance and luminous performance of the element; the color correction coefficient, which is related to the color accuracy and stability presented by the light-emitting element; the heat dissipation effect coefficient of the light-emitting element, good heat dissipation can ensure the stable operation of the element, thereby affecting the luminous quality; the distance attenuation coefficient corresponding to the light-emitting element, the distance will cause the observed light intensity to be different. Optionally, the mining of the lighting influence factor of the light-emitting element can be achieved through optical simulation tools, such as COMSOL, TRACEPRO and other tools.

[0050] Furthermore, the present invention calculates the luminous brightness of the controlled light-emitting element based on the light impact factor, which can achieve accurate prediction and control of the luminous brightness. The required luminous brightness can be accurately set according to specific usage requirements and environmental conditions, avoiding excessive brightness or darkness, and providing the most suitable lighting effect.

[0051] The luminance refers to the brightness of the light emitted by the light-emitting element, which is a physical quantity that measures the intensity of light output and is usually expressed in units such as candela (cd) and lumen (lm).

[0052] As an embodiment of the present invention, the calculating the luminous brightness of the controlled light-emitting element based on the light impact factor includes:

[0053] The luminous brightness of the controlled light emitting element is calculated using the following formula:

[0054]

[0055] Among them, L represents the luminous brightness of the controlled light-emitting element, P represents the input power of the light-emitting element, η represents the luminous efficiency of the light-emitting element, S represents the environmental sensitivity coefficient, C represents the color correction coefficient corresponding to the light impact factor, A represents the heat dissipation effect coefficient of the light-emitting element, and D represents the distance attenuation coefficient corresponding to the controlled light-emitting element.

[0056] Specifically, the environmental sensitivity coefficient is a parameter used to measure the degree of influence of environmental factors on the brightness of a light-emitting element. Environmental factors may include temperature, humidity, air pressure, etc. For example, in a high-temperature environment, the performance of a light-emitting element may decline, and the environmental sensitivity coefficient will decrease accordingly, thereby reducing its value when calculating the brightness. The color correction coefficient is used to correct the influence of color deviation caused by the characteristics of the light-emitting element itself or external factors on the brightness. The heat dissipation effect coefficient reflects the influence of the heat dissipation of the light-emitting element on its brightness. Good heat dissipation can keep the light-emitting element at a suitable operating temperature, thereby emitting light stably. The distance attenuation coefficient refers to the degree of brightness attenuation caused by the increase in distance during the propagation of light. The longer the distance, the more serious the light divergence, and the weaker the light intensity reaching the observation point.

[0057] S4. Collecting operating data of the cooling fan, defining a lighting mechanism for controlling the light-emitting element based on the operating data and the light brightness, and performing lighting control of the cooling fan through the lighting mechanism.

[0058] By collecting the operating data of the cooling fan, the present invention can fully understand the performance of the fan under different working conditions, thereby judging whether it meets the design requirements and performance standards, and can adjust the fan's working mode, control parameters, etc. to achieve more efficient cooling effect and lower energy consumption.

[0059] Among them, the operating data refers to various parameters and information related to the actual operation of the cooling fan, such as the fan speed, that is, the number of revolutions per minute of the fan blades, which reflects the working speed of the fan; the temperature of the fan when working, including the temperature of the internal components and the ambient temperature, which is very important for evaluating the heat dissipation effect and the thermal stability of the components; the current and voltage of the fan, which can reflect its energy consumption and the stability of the power supply; the noise level generated by the fan, which affects the comfort of the use environment; the vibration amplitude of the fan, excessive vibration may indicate problems with the installation or components; and data such as the fan's operating time, number of starts and stops, etc. Optionally, the collection of the cooling fan's operating data can be achieved through an interface reading method, such as USB, RS232, etc.

[0060] The present invention defines the lighting mechanism of the light-emitting element based on the operating data and the luminous brightness, which can achieve a close association between the operating status of the cooling fan and the lighting effect, and can realize automatic adjustment and optimization of the fan light, which helps to enhance the user's interactive perception of the device.

[0061] Among them, the light-emitting mechanism refers to the rules, patterns and methods for controlling how the light-emitting element emits light according to the operating data of the cooling fan and the calculated light-emitting brightness, which covers specific operating methods and forms of expression such as turning on or off the light-emitting element, adjusting the brightness, changing the color, setting the flashing frequency under different operating conditions (such as different speeds, temperatures, workloads, etc.). Optionally, the definition of the light-emitting mechanism for controlling the light-emitting element can be implemented through HDL tools, such as Ver il og, VHDL and other tools.

[0062] The present invention controls the lighting of the cooling fan through the light-emitting mechanism, can provide intuitive and real-time feedback, enhance the interactivity between the user and the device, can conveniently perform overall status monitoring and management, and improve the overall efficiency and stability of the system.

[0063] Among them, the lighting control refers to a series of operations and settings for managing and manipulating the lighting effects of the light-emitting elements on the cooling fan, which may include turning the light on and off, adjusting the brightness, switching the color, selecting the flashing mode, the frequency and rhythm of the light changes, etc. Optionally, the lighting control of the cooling fan can be implemented through a serial communication protocol, such as: I2C, SPI and other protocols.

[0064] refer to Figure 4-5, a lighting control system for a cooling fan with a dual halo, comprising a DMX512 lighting control module 300 and an external sensing module 400, and a cooling fan with a dual halo according to any one of claims 1 to 7, the external sensing module 400 being connected to the DMX512 lighting control module 300, the external sensing module 400 being a temperature sensor installed in a device used for the cooling fan, in this embodiment, the external sensing module 400 being a temperature sensor separately arranged in the cooling fan device, which is fixedly arranged on the circumference of the fan frame 1 for detecting the temperature around the fan, the DMX512 lighting control module 300 comprising a lighting unit 301, a Bluetooth connection unit 302 and a control page unit 303 connected in sequence, the lighting unit 301 comprising a first light-emitting element 61 and a second light-emitting element 62, the Bluetooth connection unit 302 being a BLE Bluetooth module 306 arranged on the mainboard 4, the Bluetooth connection unit 302 being connected to the Bluetooth of the fan device, and the control page unit 303 being an operation page controlled by the cooling fan device.

[0065] Specifically, the lighting unit 301 is connected to the main board 4. The lighting unit 301 also includes a relay 304 and an AC to DC power supply module HLK-PM01305 set on 4. The temperature sensor of the external sensing module 400 is electrically connected to the fan using equipment. The first light-emitting element 61 and the second light-emitting element 62 are both composed of multiple color-changing LED lamp beads in series, and are electrically connected to the relay 304 and the AC to DC power supply module HLK-PM01305. The lighting unit 301 can control the lights of the first light-emitting element 61 and the second light-emitting element 62. Specifically, the relay can be controlled by a Bluetooth signal, thereby controlling the switch of the color-changing LED lamp beads and the change of color. The AC to DC power supply module HLK-PM01 provides a stable power supply for the entire system to ensure the normal operation and stable operation of the equipment.

[0066] Take a computer host as an example: the cooling fan with dual halo in the present invention is installed on the computer motherboard, and is connected to the BLE Bluetooth module through the computer's built-in Bluetooth. The control page unit 303 is a web page or APP that the computer needs to download for controlling the DMX512 lighting control module 300. The web page or APP can be used to control the transmission of Bluetooth signals to the Bluetooth connection unit 302. The Bluetooth connection unit 302 receives the signal and transmits the instruction to the lighting unit 301, so that the first light-emitting element 61 and the second light-emitting element 62 can operate, and the color-changing LED lamp beads can also be set to the user's favorite color as needed.

[0067] It should also be noted that the external sensing module 400 also includes collecting the temperature parameters per unit time inside the cooling fan device under normal operating conditions, and setting a high temperature threshold through the parameters. In this embodiment, the high temperature threshold is the highest temperature during normal operation of the device. When the temperature of the device is higher than the threshold during later transportation, the external sensing module 400 transmits the information to the control page unit 303 through the Bluetooth connection unit 302, and the control page unit 303 automatically issues instructions to the lighting unit 301 to emit a specific alarm light.

[0068] Let's take the computer host as an example: when the computer host is transported normally, the external sensing module 400 will record its operating temperature through the temperature sensor. When the temperature exceeds the set threshold, the temperature sensor will transmit the signal to the DMX512 lighting control module 300, and the Bluetooth connection unit 302 will transmit the signal to the control page unit 303. The high temperature alarm information is displayed on the page of the control page unit 303 to remind the user, and the control page unit 303 will also automatically issue instructions to make the first light-emitting element 61 and the second light-emitting element 62 generate an alarm light. It should be noted that the alarm light will not be generated during normal use, so the control page unit 303 will set a backup light color as the alarm light. It should also be noted that as many existing computer motherboards have built-in temperature sensors, the control page unit 303 can directly request temperature information, and there is no need to install a temperature sensor outside the fan frame.

[0069] The above is only a preferred specific embodiment of the invention, but the scope of protection of the invention is not limited to this. Any technician familiar with this technical field can make equivalent substitutions or changes within the technical scope disclosed by the invention based on the technical solution and inventive concept of the invention, which should be covered by the scope of protection of the invention.
