Description

Technical Field

[0001] The present application relates to the technical field of vehicle lighting, and more particularly to a method, device, computer equipment and storage medium for reducing LED light decay. Background Art

[0002] LED lamps widely used in motorcycle lighting systems have the advantages of low energy consumption and long life. However, as the use time increases, LED lamps will experience light decay, resulting in a decrease in lighting effect. This problem not only affects driving safety, but also reduces the user experience. Therefore, finding an effective solution has become one of the focuses of current research.

[0003] The commonly used methods to solve the problem of LED light decay mainly include: improving the heat dissipation design of LED lamps, such as using more efficient heat sinks or heat pipes to enhance the heat dissipation capacity; selecting high-quality LED chips and packaging materials to improve the durability of LED lamps; adopting modular design to facilitate the replacement of problematic modules; implementing regular maintenance plans to ensure that LED lamps work in the best condition; providing user guides and educational materials to teach users how to properly use and maintain LED lamps.

[0004] Although the above methods can alleviate the light decay problem of LED lamps to a certain extent, there are still some shortcomings, such as the inability to monitor and dynamically adjust the brightness of LED lamps in real time, and it is difficult to achieve precise control, thus limiting the stability of lighting effects in practical applications. Therefore, there is an urgent need for a method that can detect the brightness changes of LED lamps in real time and make corresponding adjustments to further improve and stabilize the lighting quality. Summary of the invention

[0005] In order to improve the flexibility of adjusting the working state of LED lights on motorcycles or electric vehicles, the present application provides a method, an apparatus, a computer device and a storage medium for reducing the light decay of LED lights.

[0006] The above-mentioned invention objective of the present application is achieved through the following technical solutions: A method for reducing LED light decay, the method for reducing LED light decay comprising: Obtaining a vehicle startup message, and obtaining an LED light startup instruction from the vehicle startup message; Acquire the number of LED lamp beads to be started according to the LED lamp start instruction, and calculate the number of power supplies to be started according to the number of LED lamp beads to be started; Respond to the LED lamp start instruction according to the number of power supplies to be started, and detect LED brightness data in real time to obtain real-time LED lamp bead brightness data; When the LED lamp bead brightness data is lower than a preset value, a light decay compensation instruction is generated, and a power supply additional instruction is generated according to the light decay compensation instruction to increase the LED lamp bead brightness data to above the preset value.

[0007] By adopting the above technical solution, the intelligent management and control of LED lights is realized by obtaining the vehicle startup message and extracting the LED light startup instruction from it. On this basis, the number of LED lamp beads to be started is further obtained according to the LED light startup instruction, and the required number of power supplies to be started is calculated based on this, which not only improves the power supply utilization efficiency but also reduces unnecessary energy consumption. Then, the LED light startup instruction is responded to according to the calculated number of power supplies to be started, and the brightness data of the LED lamp beads is detected in real time, so that any brightness change trend can be captured at the first time. If the system detects that the brightness data of the current LED lamp beads has dropped below a predetermined threshold, a light decay compensation instruction will be automatically generated, which triggers a new power module to join the work, thereby supplementing the original light source shortage, and then the overall LED lamp bead brightness is restored or even exceeds the initial setting level. By taking flexible response measures to different light decay phenomena, the stability of the lighting system and the user experience are significantly improved, especially for those application scenarios with high requirements for lighting quality, such as long-distance riding or night driving. In addition, this method can freely adjust parameter settings according to factors such as different vehicle models, road conditions and environmental conditions, and has strong practical operational flexibility and adaptability. It can effectively suppress LED light decay through a combination of intelligent control technology and precise resource allocation, thereby ensuring the long-term and efficient operation of motorcycle lighting devices.

[0008] In a preferred example, the present application can be further configured as follows: responding to the LED lamp start instruction according to the number of power supplies to be started, and detecting LED brightness data in real time to obtain real-time LED lamp bead brightness data, specifically including: Generate a multi-power supply startup instruction according to the number of power supplies to be started, obtain the PWM time base frequency of the first power supply module, and generate a SYNC pulse waveform according to the PWM time base frequency; The SYNC pulse waveform is used to synchronize power modules according to the number of power supplies to be started; After obtaining the module synchronization response corresponding to the power module synchronization, generating a time base synchronization instruction according to the SYNC pulse waveform; After obtaining the time base synchronization response corresponding to the time base synchronization instruction, respond to the LED lamp start instruction according to the number of power supplies to be started.

[0009] By adopting the above technical solution, by obtaining the vehicle startup message and extracting the LED light startup instruction from it, the number of LED lamp beads to be started and the number of power supplies required can be determined. In this process, the synchronous startup of multiple power modules is realized, that is, the multi-power startup instruction is generated according to the number of power supplies to be started, and the PWM time base frequency of the first power module is further obtained, and the SYNC pulse waveform is generated based on this frequency. Then, the SYNC pulse waveform is used to synchronize the various power modules, so as to achieve the synchronous startup of multiple power converters at the same time point. In this way, it is possible to effectively avoid the situation where other modules enter the protection mode in sequence due to overpower detection due to the priority startup of a single power module. When all power modules can start and work normally, the brightness of the LED lamp beads can be maintained at a stable level, reducing the impact of the overpower protection problem caused by the startup sequence of the power modules on the overall lighting system. In addition, by real-time monitoring of the brightness data of the LED lamp beads, and immediately generating a light decay compensation instruction when the brightness is detected to be lower than the preset value, and then triggering the power supply new instruction, the brightness of the LED lamp beads can be quickly restored to above the preset value, which not only helps to delay the development of the light decay phenomenon, but also can ensure the stable output of the LED lamp under various conditions of use. Furthermore, by precisely controlling the PWM time base frequency and sending synchronization instructions, it is effectively ensured that all power modules can work together under optimal conditions, improving the efficiency of the entire system while enhancing the overall service life and performance stability of the LED lamp. Therefore, it can not only significantly improve the over-power protection problem of LED lamps caused by the startup sequence of power modules in the prior art, but also realize a more efficient and reliable brightness maintenance mechanism through intelligent monitoring and control means, thereby greatly improving the user experience of LED lamps in practical applications.

[0010] In a preferred example, the present application can be further configured as follows: when the LED lamp bead brightness data is lower than a preset value, a light attenuation compensation instruction is generated, specifically including: Obtaining the LED light decay value of the LED lamp bead brightness data lower than the preset value, and calculating the additional amount of LED lamp beads according to the LED light decay value; The newly added number of power modules is calculated according to the newly added number of LED lamp beads, and the light attenuation compensation instruction is generated according to the newly added number of power modules.

[0011] By adopting the above technical solution, when it is detected that the brightness data of the LED lamp beads is lower than the preset reference value, the specific value of the LED light decay can be automatically identified, and the number of new LED lamp beads required can be determined based on this value. Furthermore, based on the calculated new amount, the required number of power module additions is estimated, and the corresponding light decay compensation instructions are automatically generated accordingly, thereby achieving the goals of intelligent management and precise regulation, and can also greatly improve the overall brightness level and stability of the light source system without significantly increasing energy consumption. By adopting differentiated strategies for light decay phenomena in different situations, that is, starting the corresponding number of power modules for different degrees of light decay to activate the corresponding LED lamp beads, it is possible to more efficiently and flexibly respond to the challenges brought by various complex environmental conditions. Therefore, the problem of light intensity fluctuations encountered during daily driving or driving under special climatic conditions can be effectively alleviated, thereby greatly improving the application life of the LED light source and its reliability and user experience in the entire vehicle lighting system.

[0012] In a preferred example, the present application can be further configured as follows: the calculation of the number of power modules added according to the number of LED lamp beads added, and the light attenuation compensation instruction generated according to the number of power modules added, specifically including: Obtaining the power supply identifier to be started according to the newly added number of the power supply modules; The current time base frequency data is acquired, a second SYNC pulse waveform is generated according to the current time base frequency data, and a new power supply startup instruction is generated according to the power supply identifier to be started by using the second SYNC pulse waveform to generate the light attenuation compensation instruction.

[0013] By adopting the above technical solution, when it is detected that the brightness data of the LED lamp beads is lower than the preset threshold, a light decay compensation instruction will be automatically generated, and the number of additional power modules required will be calculated based on this instruction. Based on the determined number of additional power modules, the specific identification of the power supply to be started is further obtained. At the same time, by capturing the current time base frequency data and generating a new SYNC pulse waveform based on it, and using the waveform signal to trigger the new power start instruction, the brightness of the LED lamp beads is effectively restored, so that its brightness reaches or exceeds the predetermined standard, which not only helps to prevent the decline in lighting quality caused by light decay, but also can realize refined management by dynamically allocating the corresponding number of power modules for different light decay levels, thereby improving the flexibility and energy efficiency of the overall system, reducing energy consumption and enhancing user experience. Through this precise control mechanism, an appropriate number of fresh power supply points can be added in time according to actual needs, so that the LED lamp always works within an ideal brightness range, and even in the long-term use process, the influence of the natural decay trend of light intensity can be reduced, so that it can still show strong adaptability to complex and changeable application environment conditions and diverse user preferences.

[0014] In a preferred example, the present application may be further configured as follows: the step of obtaining the power supply identifier to be started according to the newly added number of the power supply modules specifically includes: Obtaining the operating battery position and the backup battery identifier, and obtaining the corresponding backup battery position according to the backup battery identifier; The power supply temperature data at the operating battery position is obtained, and the to-be-started power supply identifier is obtained at the backup battery position according to the power supply temperature data and the newly added number of the power modules, so as to reduce the influence of battery heating on light decay.

[0015] By adopting the above technical solution, the backup power source identifier to be activated is selected by combining the battery location information, ensuring that the temperature data of the existing power source is given priority when selecting an additional power supply path. Therefore, while minimizing the heat accumulation problem caused by improper power layout on the printed circuit board or long-term operation, it also minimizes the impact of battery heating on the overall light decay phenomenon.

[0017] By adopting the above technical solution, the intelligent management and control of LED lights is realized by obtaining the vehicle startup message and extracting the LED light startup instruction from it. On this basis, the number of LED lamp beads to be started is further obtained according to the LED light startup instruction, and the required number of power supplies to be started is calculated based on this, which not only improves the power supply utilization efficiency but also reduces unnecessary energy consumption. Then, the LED light startup instruction is responded to according to the calculated number of power supplies to be started, and the brightness data of the LED lamp beads is detected in real time, so that any brightness change trend can be captured at the first time. If the system detects that the brightness data of the current LED lamp beads has dropped below a predetermined threshold, a light decay compensation instruction will be automatically generated, which triggers a new power module to join the work, thereby supplementing the original light source shortage, and then the overall LED lamp bead brightness is restored or even exceeds the initial setting level. By taking flexible response measures to different light decay phenomena, the stability of the lighting system and the user experience are significantly improved, especially for those application scenarios with high requirements for lighting quality, such as long-distance riding or night driving. In addition, this method can freely adjust parameter settings according to factors such as different vehicle models, road conditions and environmental conditions, and has strong practical operational flexibility and adaptability. It can effectively suppress LED light decay through a combination of intelligent control technology and precise resource allocation, thereby ensuring the long-term and efficient operation of motorcycle lighting devices.

DETAILED DESCRIPTION

[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] In one embodiment, if Figure 1 As shown, the present application discloses a method for reducing LED light decay, which specifically includes the following steps: S10: Obtain a vehicle startup message, and obtain an LED light startup instruction from the vehicle startup message.

[0024] In this embodiment, the vehicle start message refers to a message of starting a motorcycle, an electric cycle, or other small vehicles equipped with LED headlights.

[0025] Specifically, when a user needs to turn on the headlights when starting a motorcycle, electric bike or other vehicle equipped with LED headlights, after the vehicle start message is triggered and the vehicle is started, the LED light start instruction is triggered to control the operation of the vehicle's headlights.

[0026] S20: Obtain the number of LED lamp beads to be started according to the LED lamp start instruction, and calculate the number of power supplies to be started according to the number of LED lamp beads to be started.

[0027] Specifically, in this embodiment, a plurality of power modules are installed in parallel to share the current to power the LED lamp, and the number of power modules that need to be started is calculated based on the number of lamp beads started, the brightness, and the output power.

[0028] Furthermore, after obtaining the LED lamp start instruction, the number of LED lamp beads that need to be started is determined according to the ambient light data, as the number of LED lamp beads to be started, and the total power to be started is calculated based on the output power required to start each LED lamp bead, and the output power of each power module is combined to calculate the number of power supplies to be started.

[0029] S30: responding to the LED lamp start instruction according to the number of power supplies to be started, and detecting the LED brightness data in real time to obtain the real-time LED lamp bead brightness data.

[0030] Specifically, after obtaining the specific number of power sources to be started, the corresponding power supply modules are started according to the number to supply power to the LED lamp beads, so as to control the operation of the same number of LED lamp beads as the number of LED lamp beads to be started.

[0031] Furthermore, while the LED lamp beads are working, the LED brightness data is detected in real time to obtain the real-time brightness data of all LED lamp beads, that is, the brightness data of the LED lamp beads.

[0032] S40: When the LED lamp bead brightness data is lower than the preset value, a light decay compensation instruction is generated, and a power supply additional instruction is generated according to the light decay compensation instruction to increase the LED lamp bead brightness data to above the preset value.

[0033] Specifically, when the vehicle is started continuously, so that the LED headlights are continuously turned on, due to temperature and other reasons, the LED lamp beads will experience light decay, thereby reducing the brightness of the lighting. Therefore, when it is detected that the LED lamp bead brightness data is lower than the preset value, it proves that the light decay phenomenon has affected the driver's normal night driving, and the light decay compensation instruction is triggered to control other backup power supplies to turn on more LED lamp beads and / or increase the output power of the LED lamp beads that have been turned on, thereby increasing the LED lamp bead brightness data to above the preset value.

[0034] In this embodiment, by obtaining the vehicle startup message and extracting the LED light startup instruction from it, the intelligent management and control of the LED light is realized. On this basis, the number of LED lamp beads to be started is further obtained according to the LED light startup instruction, and the number of power supplies to be started is calculated based on this, which not only improves the power supply utilization efficiency, but also reduces unnecessary energy consumption. Then, the LED light startup instruction is responded to according to the calculated number of power supplies to be started, and the brightness data of the LED lamp beads is detected in real time, so that any brightness change trend can be captured at the first time. If the system detects that the brightness data of the current LED lamp beads has dropped below a predetermined threshold, a light decay compensation instruction will be automatically generated, and the new power module will be triggered to join the work in this instruction, so as to supplement the original light source shortage, and then the overall LED lamp bead brightness will be restored or even exceed the initial setting level. By taking flexible response measures to different light decay phenomena, the stability of the lighting system and the user experience are significantly improved, which is particularly suitable for those application scenarios with high requirements for lighting quality, such as long-distance riding or night driving. In addition, this method can freely adjust parameter settings according to factors such as different vehicle models, road conditions and environmental conditions, and has strong practical operational flexibility and adaptability. It can effectively suppress LED light decay through a combination of intelligent control technology and precise resource allocation, thereby ensuring the long-term and efficient operation of motorcycle lighting devices.

[0035] In one embodiment, if Figure 2 As shown, in step S30, the LED lamp start instruction is responded to according to the number of power supplies to be started, and the LED brightness data is detected in real time to obtain the real-time LED lamp bead brightness data, which specifically includes: S31: Generate a multi-power startup instruction according to the number of power supplies to be started, obtain the PWM time base frequency of the first power module, and generate a SYNC pulse waveform according to the PWM time base frequency.

[0036] In this embodiment, the multi-power startup instruction refers to an instruction that needs to control multiple power supplies to start simultaneously to meet the requirements of load use. The first PWM time base frequency refers to the clock signal frequency in one of the power modules.

[0037] Specifically, when it is necessary to control multiple power supply modules to start simultaneously to meet the number of power supplies to be started, the clock signal frequency of one of the power supply modules is first obtained as the PWM time base frequency of the first electrical module, and a pulse waveform with the same frequency as the first PWM time base frequency is generated on the SYNC of the power supply of the module as the SYNC pulse waveform.

[0038] S32: Synchronize the power modules with the SYNC pulse waveform according to the number of power supplies to be started.

[0039] Specifically, when the multi-power startup instruction is triggered, the multi-power startup instruction is triggered according to the number of power supplies to be started. Therefore, when the multi-power startup instruction is obtained, the number of power supplies to be started is obtained from the multi-power startup instruction.

[0040] Furthermore, after obtaining the number of power supplies to be started and generating a SYNC pulse waveform in the first power module, the specific other power modules that need to be started are confirmed, and the SYNC pulse waveform is generated to synchronize the power modules so as to synchronize the SYNC pulse waveform to other power modules.

[0041] S33: After obtaining the module synchronization response corresponding to the power module synchronization, a time base synchronization instruction is generated according to the SYNC pulse waveform.

[0042] Specifically, after completing the synchronization of the SYNC pulse waveform to other power modules, the module synchronization response is generated, and the PWM clock signal frequency of the power module that receives the SYNC pulse waveform is synchronized, that is, the PWM clock signal frequency of the corresponding power module is synchronized to be consistent with the SYNC pulse waveform.

[0043] S34: After obtaining the time base synchronization response corresponding to the time base synchronization instruction, respond to the LED light start instruction according to the number of power supplies to be started.

[0044] Specifically, after the PWM clock signal frequency synchronization of other power modules is completed, the corresponding power modules are controlled to start PWM output according to the number of power supplies to be started, so as to respond to the LED lamp start instruction.

[0045] In one embodiment, if Figure 3 As shown, in step S40, when the LED lamp bead brightness data is lower than the preset value, a light attenuation compensation instruction is generated, which specifically includes: S41: Obtaining LED light decay values ​​whose LED lamp bead brightness data is lower than a preset value, and calculating the additional amount of LED lamp beads according to the LED light decay values.

[0046] Specifically, when it is detected that the LED lamp bead brightness data is lower than the preset value, the specific value below is used as the LED light attenuation value, and the additional amount of the LED lamp bead is calculated based on the amount that each LED lamp bead to be started can compensate.

[0047] S42: Calculate the number of new power modules according to the number of new LED lamp beads, and generate a light attenuation compensation instruction according to the number of new power modules.

[0048] Specifically, the total output power is calculated based on the output power of each LED lamp bead to be started and the newly added number of LED lamp beads, and then the newly added number of power modules is calculated based on the output power of each power module when it is working, and the light attenuation compensation instruction is generated based on the newly added number of power modules.

[0049] In one embodiment, if Figure 4 As shown, in step S42, the number of new power modules is calculated according to the number of new LED lamp beads, and a light attenuation compensation instruction is generated according to the number of new power modules, which specifically includes: S421: Obtain the identifier of the power supply to be started according to the number of newly added power modules.

[0050] In this embodiment, the power increase request refers to an instruction requesting to add a power module.

[0051] Specifically, real-time re-forecasting is performed based on the current actual power consumption situation. When the power consumption is predicted to exceed the power change trend corresponding to the current time, the number of power modules that need to be added and the identification of the specific power module that needs to be started are calculated based on the excess amount and the output power of each power module as the identification of the power supply to be started.

[0052] S422: Acquire current time base frequency data, generate a second SYNC pulse waveform according to the current time base frequency data, and generate a new power supply startup instruction according to the power supply identifier to be started, so as to generate a light attenuation compensation instruction.

[0053] Specifically, the clock signal frequency of the started power module is obtained as the current time base frequency data, a second SYNC pulse waveform with the same frequency is generated according to the current time base frequency data, and a new power startup instruction is generated according to the second SYNC pulse waveform to control each power module corresponding to the power identification to be started to start PWM output according to the second SYNC pulse waveform to respond to the light attenuation compensation instruction.

[0054] In one embodiment, if Figure 5 As shown, in step S421, the power source identifier to be started is obtained according to the number of newly added power modules, which specifically includes: S4211: Obtain the operating battery position and the backup battery identifier, and obtain the corresponding backup battery position according to the backup battery identifier.

[0055] In this embodiment, the operating battery position refers to the relative position of the power module currently in working state in the entire battery. The standby battery identifier refers to the unique identifier corresponding to the power module not in working state.

[0056] Specifically, when the power supply is installed, the corresponding power modules are installed in a predetermined arrangement order, and when starting, the corresponding number of power modules are started in a preset first order to obtain the running battery position, and the identifier of the remaining unstarted power module is used as the backup battery identifier, and its corresponding installation position is used as the backup battery position.

[0057] S4212: Acquire power temperature data at the operating battery position, and acquire a power identification to be started at the standby battery position according to the power temperature data and the number of newly added power modules, so as to reduce the impact of battery heating on light decay.

[0058] Specifically, the temperature of the currently started power module is detected in real time as the power temperature data. If the power temperature data is at a normal value, the power module to be started is obtained according to the first order in step S4211 and the newly added number of power modules as the identification of the power supply to be started. If the power module data is higher than the normal value, the identification of the power supply to be started is obtained according to the preset second order, so that the position of the power supply to be started is away from the position of the running battery, thereby reducing the influence of power supply heating on light attenuation.

[0059] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
