Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a control method for an explosion-proof portable lamp. Background Technology

[0002] Explosion-proof portable lights are mobile lighting devices used in flammable and explosive environments. They are commonly used in rescue operations in petroleum, chemical, mining, metallurgy, and fire fighting industries, serving as on-site lighting and operational assistance in environments containing explosive gases, vapors, or dust.

[0003] Existing explosion-proof portable lights have relatively limited lighting modes, supporting only high beam or floodlight modes, and typically lack switching functionality, preventing them from adapting to changes in the activity environment. In contrast, fixed explosion-proof portable lights are typically capable of adjusting lighting according to environmental changes. For example, Chinese invention patent CN118488630B discloses an explosion-proof light control method. Specifically, it discloses a technical solution that determines the initial brightness by acquiring environmental information and area type of the target explosion-proof light, then adjusts the target brightness based on the behavior of personnel within the illumination range, and finally determines the final brightness by coordinating the brightness of adjacent explosion-proof lights. This achieves multi-level intelligent control of the explosion-proof light brightness to match the lighting needs of mines.

[0004] While the aforementioned disclosed technical solutions can determine lighting brightness based on environmental information and area type to improve the adaptability of explosion-proof lights to different environments, their implementation involves the joint control of multiple fixed explosion-proof lights in different areas. This makes them unsuitable for direct application to explosion-proof portable lights that can adapt to changes in the environment as workers move around. Furthermore, the existing lighting control strategies merely adjust the brightness of the lights to adapt to environmental changes, altering only the intensity of the illumination but not its spatial distribution. Therefore, even if the control methods for existing fixed explosion-proof lights were directly applied to explosion-proof portable lights that move with operators, the technical problem of their limited lighting modes—supporting only high beam or floodlight modes and typically lacking switching functionality—remains unresolved, preventing them from adapting to changing lighting needs based on the environment.

[0005] Therefore, this invention application provides a control method for an explosion-proof portable lamp, aiming to solve the above-mentioned problems. Summary of the Invention

[0006] In view of this, embodiments of the present invention provide a control method for explosion-proof portable lamps to solve the technical problem that existing explosion-proof portable lamps have a relatively simple lighting mode, which makes them unable to change lighting requirements with changes in the activity environment.

[0007] This invention provides a control method for an explosion-proof portable lamp. The explosion-proof portable lamp includes a lamp head assembly and a lamp body assembly, which are hinged together. The lamp head assembly includes a lamp plate, a light-distributing lens, and a light-diffusing cover. The light-distributing lens side can form focused and / or floodlight output, and the light-diffusing cover side can form uniform light output. The method includes: The system acquires a first start signal and outputs a voice prompt asking whether to turn on the lighting. If a second start signal is acquired within a first preset time, the system drives the light panel to illuminate. If a second start signal is not acquired within the first preset time, the system returns to the state of acquiring the first start signal. Obtain environmental change information and determine the target lighting mode recommendation result based on the environmental change information; wherein, the target lighting mode includes spotlight mode, floodlight mode, spotlight and floodlight simultaneously on mode, uniform light mode and warning mode; Based on the recommended target lighting mode, a voice prompt is output. If a mode confirmation signal is obtained within a second preset time, the corresponding area of ​​the light panel is controlled to light up or flash according to the mode confirmation signal to switch the lighting mode. If no mode confirmation signal is obtained within the second preset time, the lighting mode at startup is maintained.

[0008] Preferably, the step of acquiring a first activation signal and outputting a voice prompt to ask whether to turn on the lighting, and if a second activation signal is acquired within a first preset time, then driving the lamp panel to illuminate; if the second activation signal is not acquired within the first preset time, then returning to the state of acquiring the first activation signal includes: Obtain the first start signal from the switch button; The first activation signal is a short press of the switch button; Within the first preset time period, a second activation signal of the switch button or a second activation signal of the voice button is acquired; wherein, the second activation signal of the switch button is a long press of the switch button, and the second activation signal of the voice button is a short press of the voice button; If a second start signal is received from the switch button, the lamp panel will be directly driven to provide illumination. If a second activation signal is received from the voice button, the system enters voice interaction mode and outputs a voice prompt again asking whether to turn on the lighting. When a voice command to turn on the lighting is received, the light panel is driven to illuminate.

[0009] Preferably, the explosion-proof portable lamp further includes an ambient light sensor, a distance sensor, and a gas sensor, which are disposed on the lamp body assembly or the lamp head assembly; the step of acquiring environmental change information and determining the target lighting mode recommendation result based on the environmental change information includes: The ambient light sensor collects the ambient brightness value, the target distance value collected by the ranging sensor, and the gas concentration value collected by the gas sensor are obtained. When the target distance value is greater than the first distance threshold, the target illumination mode is recommended to be the spotlight mode; When the target distance value is greater than the second distance threshold and less than or equal to the first distance threshold, and the ambient brightness value is lower than the first brightness threshold, the recommended target lighting mode is a simultaneous spotlight and floodlight mode. When the target distance value is greater than the third distance threshold and less than or equal to the second distance threshold, the recommended target illumination mode is floodlight mode; When the target distance value is less than or equal to the third distance threshold, the target illumination mode is recommended to be uniform light mode; When the gas concentration value meets the preset warning value, the target lighting mode is recommended as the warning mode, and the recommendation priority of the warning mode is higher than the spotlight mode, floodlight mode, spotlight and floodlight simultaneously mode, and uniform light mode. Wherein, the first distance threshold is greater than the second distance threshold, and the second distance threshold is greater than the third distance threshold.

[0010] Preferably, the lamp assembly includes a main control board, which integrates a voice broadcast module; the step of outputting voice prompts based on the target lighting mode recommendation result, and if a mode confirmation signal is obtained within a second preset time, controlling the lamp panel to light up or flash the corresponding area according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is obtained within the second preset time, the step of maintaining the lighting mode at startup further includes: The voice broadcast module is invoked to output voice prompts corresponding to the target lighting mode. The voice prompts include at least a mode name and a switching suggestion. The mode names include spotlight, floodlight, spotlight and floodlight on simultaneously, uniform light, and warning. When the target lighting mode is warning mode, the voice prompt content also includes risk warning information to remind the operator to pay attention to the abnormality of the current environment; After the voice prompt, a confirmation message is output via voice to prompt the operator to confirm the mode using the preset input method among the switch button, voice button, or warning button.

[0011] Preferably, the step of outputting a confirmation prompt via voice after the voice prompt, to guide the operator to complete the mode confirmation through a preset input method among the switch button, voice button, or warning button, includes: Obtain the voice button trigger signal or the warning button trigger signal; After the voice button trigger signal is obtained, the operator's voice confirmation command is obtained within a third preset time period, the voice confirmation command is recognized, and the mode confirmation result is obtained. If no voice confirmation command is received within the third preset time, the switch button trigger signal is obtained, and the corresponding mode confirmation result is obtained based on the number of times the switch button triggers the signal within the fourth preset time. Based on the mode confirmation result, control the light panel to adopt the target lighting mode recommendation result or switch to the lighting mode specified by the operator; When a warning button trigger signal is received, the warning button trigger signal is used as a warning mode confirmation input to control the light panel to enter the warning mode.

[0012] Preferably, the light-distributing lens includes a focusing part and a floodlight part, with the floodlight parts respectively disposed on both sides of the focusing part; the step of outputting a voice prompt based on the target lighting mode recommendation result, and if a mode confirmation signal is obtained within a second preset time, controlling the lamp panel to light up or flash the corresponding area according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is obtained within the second preset time, maintaining the lighting mode at startup includes: When the target lighting mode is focused mode, the LED beads in the area corresponding to the focusing part on the side of the light distribution lens are lit. When the target lighting mode is floodlight mode, the LED beads in the area corresponding to the floodlight section on the side of the light distribution lens are lit. When the target lighting mode is the simultaneous activation of spotlight and floodlight, the LED beads in the area corresponding to the spotlight and floodlight in the control lens side are lit up simultaneously. When the target lighting mode is uniform lighting mode, control the LED beads in the corresponding area on the uniform light cover side to light up, and turn off the LED beads in the corresponding area on the light distribution lens side. When the target lighting mode is warning mode, the LED beads in the preset warning light area are controlled to flash according to the preset warning frequency and duty cycle.

[0013] Preferably, the lamp body assembly and the lamp head assembly are hinged via a rotating hole and a rotating shaft; the explosion-proof portable lamp further includes a magnetic encoder, which includes a magnetic rotor and a magnetic sensor, the magnetic rotor and the magnetic sensor being respectively disposed at the hinge positions corresponding to the rotating hole and the rotating shaft; the step of acquiring environmental change information and determining the target lighting mode recommendation result based on the environmental change information further includes: Obtain the hinge angle information of the lamp head assembly relative to the lamp body assembly; The target lighting pattern recommendation result is corrected based on the hinge angle information and the environmental change information; When the hinge angle information indicates that the lamp head is facing a close-range working surface, the recommended priority of floodlight mode or uniform light mode is increased. When the hinge angle information indicates that the lamp head is facing a distant area, the recommended priority of the focusing mode is increased.

[0014] Preferably, the explosion-proof portable light further includes an indicator light, which is disposed on the light body assembly; the step of outputting a voice prompt based on the target lighting mode recommendation result, and if a mode confirmation signal is obtained within a second preset time, controlling the light panel to light up or flash the corresponding area according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is obtained within the second preset time, the step of maintaining the lighting mode at startup further includes: While outputting voice prompts, the indicator light is turned on or flashed to prompt the operator to confirm the mode. The lighting status of the indicator light is controlled according to the preset indication rules corresponding to the current target lighting mode; Different lighting modes correspond to different indicator light flashing rhythms or number of times the lights are on, so that operators can quickly identify the current recommended mode in dark environments; When the current target lighting mode is warning mode, the indicator light is controlled to emit a warning indication with a high-frequency flashing rhythm.

[0015] Preferably, the method further includes: The system continuously samples environmental change information and determines whether the magnitude of environmental change within adjacent sampling periods exceeds a preset change threshold; wherein the environmental change information includes at least one of environmental brightness information, target distance information, and environmental risk information. When the preset change threshold is exceeded, the voice prompt update process is triggered to regenerate the target lighting mode recommendation result and output new voice prompt information; When environmental risk information meets the preset warning trigger conditions, the voice prompt update process of the warning mode will be triggered first. When the preset change threshold is not exceeded and the preset warning trigger condition is not met, the current lighting mode is maintained to reduce operational interference caused by frequent switching.

[0016] Preferably, the method further includes: After switching to the target lighting mode, record the current environmental changes, the target lighting mode, and the operator's confirmation results; When similar environmental change information is detected in the future, the lighting mode corresponding to the historical confirmation result is used as the target lighting mode recommendation result, and a voice prompt message is output for confirmation. Among them, similar environmental change information is determined at least based on threshold range matching of environmental brightness information, target distance information and environmental risk information; When historical confirmation results correspond to an alert mode and the current environmental risk information again meets the corresponding alert triggering conditions, the alert mode is recommended first.

[0017] Beneficial effects: Compared with the prior art, the control method for an explosion-proof portable lamp provided in this embodiment of the invention includes a lamp head assembly and a lamp body assembly, which are hinged together. The lamp head assembly includes a lamp panel, a light-distributing lens, and a light-diffusing cover. The light-distributing lens side can form focused and / or floodlight output, and the light-diffusing cover side can form uniform light output. The method includes: acquiring a first start signal and outputting a voice prompt to indicate whether to turn on the lighting; if a second start signal is acquired within a first preset time, then driving the lamp panel to illuminate; if the second start signal is not acquired within the first preset time, then... Return to the state of obtaining the first start signal; obtain environmental change information, and determine the target lighting mode recommendation result based on the environmental change information; wherein, the target lighting mode includes spotlight mode, floodlight mode, spotlight and floodlight simultaneously on mode, uniform light mode, and warning mode; output voice prompts based on the target lighting mode recommendation result; if a mode confirmation signal is obtained within a second preset time, control the light panel to light up or flash the corresponding area according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is obtained within the second preset time, maintain the lighting mode at startup. The explosion-proof portable lamp of the present invention has a hinged structure between the lamp head assembly and the lamp body assembly, and a lamp plate, a light distribution lens and a light diffuser are set on the lamp head assembly, so that the lamp naturally has multiple light output bases such as focusing, floodlighting and light diffusion, and is no longer limited to a single lighting mode. On this basis, by acquiring environmental change information and determining the target lighting mode recommendation result accordingly, a direct correspondence is established between the external environmental state and the lighting mode selection, so that lighting control no longer depends on the operator's fixed habits or single manual switching. Furthermore, the recommended result is output through voice prompts and a mode confirmation signal is received within a preset time to realize the linkage control of environmental perception, mode recommendation and human-computer interaction confirmation. While ensuring the prevention of accidental touch and the safety of use, the lamp plate is driven to light up or flash the corresponding area to switch to the matching mode. Thus, the explosion-proof portable lamp can adjust the lighting mode in a timely manner according to the changes in the working environment, solving the problem that the existing explosion-proof portable lamps have relatively single lighting modes and cannot adapt to lighting needs with changes in the environment.

[0021] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0023] It should be noted that all actions involving the acquisition of signals, information, or data in this invention are carried out in compliance with the relevant data protection laws and regulations of the locality and with authorization from the owner of the relevant device.

[0024] Please see Figures 1 to 3 This invention provides a control method for an explosion-proof portable lamp, the explosion-proof portable lamp comprising a lamp head assembly 1 and a lamp body assembly 2, the lamp head assembly 1 and the lamp body assembly 2 being hinged together; the lamp head assembly 1 includes a lamp plate 11, a light-distributing lens 12 and a light-diffusing cover 13, the light-distributing lens 12 being capable of forming focused and / or floodlight emission, and the light-diffusing cover 13 being capable of forming uniform light emission; the method includes: The system acquires a first start signal and outputs a voice prompt asking whether to turn on the lighting. If a second start signal is acquired within a first preset time, the system drives the lamp panel 11 to illuminate. If a second start signal is not acquired within the first preset time, the system returns to the state of acquiring the first start signal. In this embodiment, the first start signal is an initial trigger signal used to activate the lighting control process, the second start signal is a secondary confirmation signal used to confirm the lighting is turned on, and the first preset time is a time parameter used to limit the confirmation window, such as a confirmation period of 1 to 5 seconds. The lamp board 11 is the light-emitting execution carrier that carries the LED beads and the driver connection relationship. This step establishes an anti-accidental activation mechanism in explosion-proof scenarios, preventing operators from accidentally turning on the lighting fixture after carrying, bumping, or wearing gloves, thereby reducing unnecessary power consumption and the risk of accidental triggering; it balances response speed and operational safety.

[0025] Specifically, in the above embodiment, the main control board continuously monitors key inputs or the low-power wake-up channel. Upon detecting the first start signal, it first calls the voice broadcast module to prompt whether to turn on the lighting and starts the first preset timer. If the second start signal is detected within the timer window, the main control board sends a power-on command to the LED driver circuit, driving the light board 11 into the default lighting state. If the second start signal is not detected within the timeout period, the main control board clears the current wake-up state and returns to standby monitoring. This step establishes an anti-accidental touch control link through a secondary confirmation mechanism, which is especially suitable for use scenarios with complex and frequent actions and a high probability of accidental touch in explosion-proof operations. At the same time, it uses voice prompts instead of pure key prompts, improving the accessibility of interaction in dark environments and when wearing protective equipment.

[0026] Obtain environmental change information and determine the target lighting mode recommendation result based on the environmental change information; wherein, the target lighting mode includes spotlight mode, floodlight mode, spotlight and floodlight simultaneously on mode, uniform light mode and warning mode; In this embodiment, environmental change information refers to input information that reflects changes in the current working environment's lighting requirements, such as ambient brightness, target distance, and risk status. The target lighting mode recommendation result is a suggested mode calculated by the main control board based on the environmental conditions, including spotlight mode, floodlight mode, simultaneous spotlight and floodlight mode, uniform lighting mode, and warning mode. This step transforms the lighting mode selection from manual experience-based switching to environment-driven intelligent recommendation, enabling the luminaires to proactively provide more suitable lighting methods as the environment changes.

[0027] Specifically, in the above embodiments, the main control board can periodically collect environmental data or collect data triggered by events, and perform threshold comparison, priority judgment, or rule matching on the collected results to generate a recommended result for the target lighting mode. If there are many sources of environmental change information, validity verification and simple filtering can be performed first before entering the mode judgment module. This step provides a clear basis for subsequent voice prompts and mode switching, enabling the lamp to have scene adaptation capabilities, solving the problem of fixed modes and reliance on frequent manual switching in traditional explosion-proof portable lamps, and leaving expansion interfaces for the addition of more sensors in the future.

[0028] Based on the recommended target lighting mode, a voice prompt is output. If a mode confirmation signal is obtained within a second preset time, the corresponding area of ​​the light panel 11 is controlled to light up or flash according to the mode confirmation signal to switch the lighting mode. If no mode confirmation signal is obtained within the second preset time, the lighting mode at startup is maintained.

[0029] In this embodiment, the mode confirmation signal is an input signal from the operator to confirm or change the recommended mode, which can come from a button or voice. The second preset time is the mode confirmation window, used to avoid the system from waiting for a long time and causing the control state to be suspended. The corresponding area is the LED bead area on the light panel 11 corresponding to different light output functions, such as a spotlight area, a floodlight area, a uniform light area, or a warning area. This step adds a human-machine confirmation link between environmental perception and actual switching, which improves efficiency by utilizing intelligent recommendations while retaining the operator's final control, meeting the controllability requirements of explosion-proof operation scenarios.

[0030] In the above embodiment, after generating the recommendation result, the main control board first announces the recommended mode and switching prompt, and starts a second preset timer. If a mode confirmation signal is received within the window, the signal is parsed to receive the recommended or specified other mode, and then a zone lighting or flashing control command is sent to the driver module; if no confirmation is received within the timeout, the mode remains unchanged at startup to avoid frequent switching of the lights due to misidentification or lack of response. This step establishes a three-stage closed-loop control of recommendation, confirmation, and execution, balancing intelligence and stability, reducing visual interference caused by erroneous switching, and achieving multi-mode output through zone lighting and warning flashing.

[0031] In the above embodiments, the explosion-proof portable lamp of the present invention has a hinged structure of lamp head assembly 1 and lamp body assembly 2, and a lamp plate 11, a light distribution lens 12 and a light dome 13 are provided on the lamp head assembly 1, so that the lamp naturally has multiple light output bases such as focusing, floodlighting and light domeing, and is no longer limited to a single lighting mode. On this basis, by acquiring environmental change information and determining the target lighting mode recommendation result accordingly, a direct correspondence is established between the external environmental state and the lighting mode selection, so that lighting control no longer depends on the operator's fixed habits or single manual switching. Furthermore, the recommended result is output through voice prompts and a mode confirmation signal is received within a preset time to realize the linkage control of environmental perception, mode recommendation and human-computer interaction confirmation. While ensuring the prevention of accidental touch and the safety of use, the lamp plate 11 is driven to light up or flash the corresponding area to switch to the matching mode, so that the explosion-proof portable lamp can adjust the lighting mode in a timely manner according to the change of the working environment, solving the problem that the existing explosion-proof portable lamps have a relatively single lighting mode and cannot adapt to lighting needs with changes in the environment.

[0032] Please see Figures 1 to 3 In one embodiment, the step of acquiring a first activation signal and outputting a voice prompt to ask whether to turn on the lighting, and if a second activation signal is acquired within a first preset time, then driving the lamp panel 11 to illuminate; if the second activation signal is not acquired within the first preset time, then returning to the state of acquiring the first activation signal includes: Obtain the first start signal from the switch button; wherein, the first start signal is a short press of the switch button; In this embodiment, the switch button is a human-machine input component on the lighting fixture used for power supply and basic control. A short press is a trigger action with a short duration, which can be clearly distinguished from a long press. Specifically, the main control board can read the button scanning signal, determine whether it is a short press based on the press duration threshold, and generate a first start signal flag after determining it to be a short press. Button scanning can be performed using either timed interrupt polling or button interrupt wake-up. This step clarifies the start entry point, reduces the probability of false judgment, and provides a clear action distinction for subsequent long presses as a second start signal, improving the consistency of interaction rules.

[0033] Within the first preset time period, a second activation signal of the switch button or a second activation signal of the voice button is acquired; wherein, the second activation signal of the switch button is a long press of the switch button, and the second activation signal of the voice button is a short press of the voice button; In this embodiment, the voice button is a dedicated button used to enter voice interaction or trigger the voice recognition process. This step splits the second activation signal into two confirmation paths: one is to continue pressing and holding the switch button to confirm, and the other is to enter voice confirmation through the voice button. This step provides a dual-channel confirmation mechanism, satisfying both users familiar with button operation and users who prefer voice interaction, and taking into account different usage habits and operating conditions while preventing accidental touches.

[0034] Specifically, the main control board simultaneously monitors the power button and voice button signals within a first preset time window. It determines whether the power button press duration is a long press or a short press, and if either condition is met, it considers a second activation signal received. If both occur simultaneously, they can be processed according to a preset priority, such as prioritizing voice interaction or prioritizing button confirmation. This step improves the flexibility of activation confirmation; the button can be used in noisy or difficult situations, while the voice path can be switched when hand operation is inconvenient, enhancing on-site adaptability.

[0035] If a second start signal is received from the switch button, the lamp panel 11 will be directly driven to provide illumination. In this embodiment, since the long press of the switch itself constitutes a secondary confirmation, it can be executed directly, avoiding unnecessary delays in secondary voice broadcasting. Direct drive means that the main control board directly outputs the lighting turn-on command without entering the voice confirmation branch, providing the operator with a quick start channel and reducing interaction layers when rapid lighting is needed.

[0036] Specifically, after confirming a long press of the switch button, the main control board can immediately recall the default lighting configuration, such as the last used mode or the preset start mode, and send a lighting command to the LED driver module. When the system supports soft start, current ramp-up control can also be added to protect the LED and power supply. This step can shorten the start-up response time, making it suitable for scenarios such as sudden inspections and emergency access, while still retaining the previous anti-accidental touch mechanism without sacrificing safety.

[0037] If a second start signal is received from the voice button, the system enters the voice interaction state and outputs a voice prompt again asking whether to turn on the lighting. When a voice command to turn on the lighting is received, the light panel 11 is driven to illuminate.

[0038] In this embodiment, a short press of the voice button indicates that the operator wishes to use voice control, therefore the system should enter the voice acquisition and recognition process. The voice interaction state is the working state in which the main control board activates its voice acquisition, recognition, and command parsing functions. The voice command to turn on the lighting can be a preset phrase, such as "turn on the lighting" or "turn on the light." This step forms a complete voice confirmation chain, allowing the second activation signal to not only serve a confirmation function but also switch to hands-free operation mode.

[0039] Specifically, after detecting a short press of the voice button, the main control board can play a prompt tone or message again, open the microphone acquisition window, and call the local speech recognition model or rule recognition module to recognize the voice command. If the lighting is recognized as being turned on, the driver board 11 will light up. If no valid command is recognized, it can retry once or exit after a timeout. This step enhances the operability of the lighting fixture in scenarios where hands are restricted, insulated gloves are worn, or tools are being handled, and the repeated voice prompts improve the clarity of the interaction, reducing erroneous actions caused by misrecognition.

[0040] Please see Figures 1 to 3 In one embodiment, the explosion-proof portable lamp further includes an ambient light sensor, a distance sensor, and a gas sensor, which are disposed on the lamp body assembly 2 or the lamp head assembly 1; the step of acquiring environmental change information and determining the target lighting mode recommendation result based on the environmental change information includes: The ambient light sensor collects the ambient brightness value, the target distance value collected by the ranging sensor, and the gas concentration value collected by the gas sensor are obtained. In this embodiment, lighting requirements are primarily determined by distance and brightness, while warning requirements can be triggered by the presence of hazardous gases. An ambient light sensor, such as a photoresistor, photodiode, or digital illuminance sensor, is used to detect the intensity of surrounding light. The target distance value is the distance parameter from the target object in the current direction of illumination by the luminaire, which can be obtained by a ranging sensor. The gas concentration value is the detected concentration of the target gas in the working environment and can be used for early warning judgment. This step concretizes environmental change information into quantifiable inputs, establishing a foundational data source for lighting recommendations and risk warnings.

[0041] Specifically, each sensor can collect data at a fixed sampling period and send it to the main control board. The main control board performs jitter reduction, filtering, or outlier removal on the brightness, distance, and gas concentration values. Distance measurement can use TOF, ultrasound, or infrared reflection methods, and gas detection can use semiconductor or electrochemical sensors. This step upgrades mode switching from a single-button logic to a multi-sensor fusion logic, improving the accuracy of mode recommendations and enabling the lighting fixtures to trigger safety warnings.

[0042] When the target distance value is greater than the first distance threshold, the target illumination mode is recommended to be the spotlight mode; In this embodiment, the greater the distance, the more concentrated the light beam needs to be to improve illuminance and visibility. The first distance threshold can be understood as the dividing line between long-distance and medium-distance lighting, such as 3 meters or 5 meters. The spotlight mode is a lighting method that concentrates the light and illuminates further. This step prioritizes the use of light patterns with stronger long-distance visibility when the target is far away, ensuring the identification of distant devices, passages, or obstacles. Specifically, the main control board compares the measured target distance value with the first distance threshold. If it is greater than the threshold, the spotlight mode is matched in the rule table as the recommended result. This judgment can be calculated in parallel with other conditions, and then prioritized. This step improves the efficiency of long-distance inspection lighting and reduces the problem of insufficient illuminance at a distance caused by the use of floodlight or uniform lighting.

[0043] When the target distance value is greater than the second distance threshold and less than or equal to the first distance threshold, and the ambient brightness value is lower than the first brightness threshold, the recommended target lighting mode is a simultaneous spotlight and floodlight mode. In this embodiment, the second distance threshold is the boundary between medium and near distances, and the first brightness threshold is the low-light environment judgment threshold. The simultaneous activation mode of spotlight and floodlight is a composite mode that simultaneously takes into account both center long-distance recognition and peripheral illumination. This step can cover complex working conditions with medium distances and relatively dark environments, where a single spotlight may not be sufficient for the perimeter, and a single floodlight may not provide enough illumination for the center. It is understandable that when the distance is in the middle range and the brightness is low, it is necessary to enhance both center and peripheral illumination. Specifically, the main control board first completes the distance range judgment, and then superimposes the brightness threshold judgment. If all three conditions are met simultaneously, the composite mode is recommended. If necessary, a brightness hysteresis range can be added to prevent boundary jitter. This step can improve environmental adaptability and is particularly suitable for scenarios such as equipment maintenance and passageway inspection, where it is necessary to see both distant signs and nearby operating areas, reducing the operator's frequent switching between spotlight and floodlight.

[0044] When the target distance value is greater than the third distance threshold and less than or equal to the second distance threshold, the recommended target illumination mode is floodlight mode; In this embodiment, the third distance threshold is the dividing line between near-field and medium-field lighting. The floodlight mode emphasizes a larger illumination range and more uniform coverage. This step provides a larger illuminated area within the near-to-medium distance range, facilitating observation of the overall work area. It is understood that when the target distance is not far, the advantage of high brightness at the center of the focused light decreases, while large-area uniform lighting becomes more practical. Specifically, when the distance value falls within this range, the main control board writes the floodlight mode into the recommendation result cache; if no higher-priority warning conditions exist simultaneously, it outputs the recommended mode. This step improves the comfort of near-field inspection and area observation, reducing the problems of localized overbrightness and peripheral underbrightness caused by strong focused light.

[0045] When the target distance value is less than or equal to the third distance threshold, the target illumination mode is recommended to be uniform light mode; In this embodiment, the uniform lighting mode creates a softer, more uniform illumination pattern by emitting light from the sides of the uniform light shield 13, making it suitable for close-range operations. This step meets the low-glare lighting requirements for close-range work surfaces, such as close-range maintenance, tag reading, and wiring checks. It is understood that at close range, excessively strong focused light or wide-area flooding can cause glare or shadows; uniform lighting is more conducive to detail observation. Specifically, the main control board compares the distance value with a third distance threshold; if the condition is met, the uniform lighting mode is recommended, and historical preferences can be used to further confirm whether uniform lighting should be prioritized. This step improves close-range work comfort and detail visibility, reduces glare interference, and is particularly beneficial for prolonged close-range operations.

[0046] When the gas concentration value meets the preset warning value, the target lighting mode is recommended as the warning mode, and the recommendation priority of the warning mode is higher than the spotlight mode, floodlight mode, spotlight and floodlight simultaneously mode, and uniform light mode. Wherein, the first distance threshold is greater than the second distance threshold, and the second distance threshold is greater than the third distance threshold.

[0047] In this embodiment, the preset warning value is a safety threshold set for the target gas, used to determine whether a risk warning state has been entered. The warning mode is a mode that highlights abnormal environmental conditions by flashing a preset area and providing a prompt. This step allows the safety risk state to be directly incorporated into the lighting control decision, enabling the lamp to not only provide illumination but also to perform an active warning function. Specifically, after each round of sensor sampling, the main control board first determines whether the gas concentration has reached the warning value. If it does, it directly sets the recommended result to the warning mode and overrides other recommended results, and then triggers subsequent voice prompts and warning flashing control. This can be combined with threshold hysteresis to avoid repeated switching near the critical concentration. This step enhances the safety assistance capability of the explosion-proof portable lamp, enabling operators to perceive risks more quickly and reducing the delayed response caused by relying solely on visual inspection or external instruments.

[0048] Please see Figures 1 to 3 In one embodiment, the lamp assembly 2 includes a main control board, which integrates a voice broadcast module; the step of outputting voice prompts based on the target lighting mode recommendation result, and if a mode confirmation signal is obtained within a second preset time, controlling the lamp panel 11 to light up or flash the corresponding area according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is obtained within the second preset time, the step of maintaining the lighting mode at startup further includes: The voice broadcast module is invoked to output voice prompts corresponding to the target lighting mode. In this embodiment, the voice broadcast module is a voice output function unit integrated on the main control board, which may include voice storage, decoding, and power amplifier driving. The voice prompt content is broadcast information generated for the current recommended mode. This step informs the operator of the system's internal recommendation results in a perceptible way, establishing a bridge for human-computer interaction. Specifically, the main control board reads the target lighting mode identifier, matches the corresponding broadcast segment from the voice resource table, and plays it; alternatively, a template splicing method can be used to combine the mode name and prompt for output. This step improves operational transparency and reduces the operator's uncertainty about the current system status, especially in dark environments where interaction can be completed without relying on a screen display.

[0049] The voice prompts include at least a mode name and a switching suggestion. The mode names include spotlight, floodlight, spotlight and floodlight on simultaneously, uniform light, and warning. In this embodiment, the mode name is a clear identifier for the recommended mode, and the switching suggestion is a prompt to guide the operator on how to confirm or adjust, such as "Please confirm switching to spotlight mode." This step ensures that the voice prompt not only tells the operator what the current recommendation is, but also explains how to proceed next, avoiding hesitation caused by overly simplistic prompts. Specifically, the voice content can be templated according to the mode, with the mode name fixed and the switching suggestion section either uniform or differentiated by mode. When playing, the main control board can first announce the mode name, followed by the confirmation prompt. This step improves the clarity and executability of voice interaction, reducing incorrect confirmations caused by mishearing or misunderstanding.

[0050] When the target lighting mode is warning mode, the voice prompt content also includes risk warning information to remind the operator to pay attention to the abnormality of the current environment; In this embodiment, the risk warning information is additional broadcast content for abnormal environmental conditions, such as indicating the presence of abnormal gas, requesting evacuation, or requiring enhanced protection. This step distinguishes the warning mode from the normal lighting mode at the voice level, highlighting the safety attributes of the warning mode. Specifically, after determining that the target mode is warning mode, the main control board calls a dedicated warning broadcast template, which can include risk reminder words, confirmation prompts, and warning sounds. If the system supports multiple risk sources, it can also output different content according to the risk type. This step enhances risk perception, enabling operators to quickly recognize environmental anomalies even when their vision is limited or their attention is distracted, thus improving on-site safety response speed.

[0051] After the voice prompt, a confirmation message is output via voice to prompt the operator to confirm the mode using the preset input method among the switch button, voice button, or warning button.

[0052] In this embodiment, the confirmation prompt is an interactive message guiding the operator to complete the mode confirmation action, and the preset input method is a confirmation path predefined by the system. This step clearly connects the mode recommendation with the confirmation action, preventing the operator from being unsure how to proceed after hearing the recommendation. Specifically, after announcing the mode content, the main control board continues to announce the confirmation prompt, such as "Press the voice button to confirm" or "Press the power button to select the mode," and then opens a second preset time window to wait for the mode confirmation signal. This step reduces interaction interruptions and misoperations, improves the confirmation success rate, and ensures that the multi-button, multi-mode system maintains good usability even under complex operating conditions.

[0053] Please see Figures 1 to 3 In one embodiment, the step of outputting a confirmation prompt via voice after the voice prompt, to prompt the operator to complete the mode confirmation through a preset input method among the switch button, voice button, or warning button, includes: Obtain the voice button trigger signal or the warning button trigger signal; In this embodiment, the voice button trigger signal is used to enter the voice confirmation branch, and the warning button trigger signal is used to quickly enter the warning mode branch. This step prioritizes listening to two types of input during the confirmation phase: one for voice confirmation and one for emergency warning. Specifically, the main control board scans the status of the voice button and the warning button within a second preset time window, and enters the corresponding branch for processing upon detecting either trigger. Debounce and press duration determination can be added to prevent accidental touches. This step makes the mode confirmation process branches clear, especially the warning button, which can serve as a fast channel, shortening the time to enter the warning mode in abnormal situations.

[0054] After the voice button trigger signal is obtained, the operator's voice confirmation command is obtained within a third preset time period, the voice confirmation command is recognized, and the mode confirmation result is obtained. In this embodiment, the third preset time is a voice acquisition window used to limit the duration of voice confirmation. The mode confirmation result is a control conclusion after parsing the voice command, such as accepting the recommendation, switching floodlight, or switching uniform light. This step provides the operator with the ability to confirm or change modes via voice, reducing the burden of key combination operations. It is understood that the operator can accept the recommendation or specify other modes based on experience, and voice recognition can support this flexibility. Specifically, after detecting the triggering of the voice button, the main control board activates the microphone for acquisition and calls the voice recognition algorithm to match the preset command vocabulary within the third preset time. The recognition result is mapped to the mode confirmation result after command parsing for subsequent drive execution. This step can improve the naturalness of human-computer interaction in mode confirmation and significantly improve interaction efficiency when hands are inconvenient to operate or the environment is dark.

[0055] If no voice confirmation command is received within the third preset time, the switch button trigger signal is obtained, and the corresponding mode confirmation result is obtained based on the number of times the switch button triggers the signal within the fourth preset time. In this embodiment, the fourth preset time is a button count window used to count the number of times the switch button is triggered. For example, single click, double click, and triple click correspond to different modes. This step provides a backup button confirmation path when voice confirmation fails or is not used, ensuring the reliability of mode confirmation. It is understood that explosion-proof environments may have noise, masks, or respiratory protection that could reduce voice recognition performance, so a button-based technical solution must coexist. Specifically, the main control board automatically switches to button count monitoring mode after voice timeout, records the number of switch button triggers within the fourth preset time window, and converts it into a mode confirmation result through a preset mapping table. If no valid count is detected when the window ends, the recommended or current mode can be maintained. This step enhances system robustness, avoids the inability to complete mode switching due to unstable voice recognition, and does not increase additional hardware costs.

[0056] Based on the mode confirmation result, control the light panel 11 to adopt the target lighting mode recommendation result or switch to the lighting mode specified by the operator; In this embodiment, the recommended result indicates that the operator confirms the system's recommendation, and switching to a specified mode indicates that the operator actively overrides the recommendation. This step executes the mode confirmation logic, completing the transition from interaction to control. Specifically, the main control board reads the mode confirmation result and calls the corresponding mode's drive parameters, such as the lighting area, drive current, flashing frequency, and duty cycle, and sends them to the LED driver module. If the mode confirmation result is empty or invalid, the recommended result can be used or the current mode can be maintained. This step balances intelligent recommendation and manual control, catering to different operator habits, while ensuring a consistent execution exit for the mode switching logic, facilitating system maintenance and expansion.

[0057] When a warning button trigger signal is received, the warning button trigger signal is used as a warning mode confirmation input to control the light panel 11 to enter the warning mode.

[0058] In the above embodiments, the warning button is a dedicated input component for quickly triggering the warning function. This step provides a one-click emergency warning channel, allowing for rapid entry into warning mode without complex confirmation. It can be directly used to serve abnormal or emergency situations, and its triggering path should be shorter and more direct. Specifically, after the main control board detects the warning button triggering during the mode confirmation stage or other permitted stages, it can skip the conventional voice confirmation and mode recommendation confirmation process, directly switch the mode status to warning mode, and load the warning flashing parameters and voice risk prompts. This step can shorten the emergency response time and improve the alarm and self-protection capabilities of operators in sudden dangerous scenarios.

[0059] Please see Figures 1 to 3 In one embodiment, the light-distributing lens 12 includes a focusing portion and a floodlight portion, with the floodlight portion disposed on both sides of the focusing portion; the step of outputting a voice prompt based on the target lighting mode recommendation result, and if a mode confirmation signal is obtained within a second preset time, controlling the lamp panel 11 to light up or flash the corresponding area according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is obtained within the second preset time, maintaining the lighting mode at startup includes: When the target lighting mode is focused mode, the LED beads in the area corresponding to the focused part on the side of the light distribution lens 12 are lit; In this embodiment, the focusing section is the light distribution area on the light-distributing lens 12 used to form a concentrated beam. This step concretizes the abstract focusing mode into the area control action of the lamp board 11, so that different modes are illuminated through different LED areas. The focusing mode corresponds to the LED beads below or at the corresponding position of the focusing section. Specifically, the main control board selects the focusing area channel according to the area mapping table of the lamp board 11, sets the corresponding drive current, and illuminates it. If necessary, PWM dimming can be used to control the brightness. This step enables long-distance illumination output, ensures that the mode control matches the optical structure, and improves the actual illumination effect of the focusing mode.

[0060] When the target lighting mode is floodlight mode, the LED beads in the area corresponding to the floodlight section on the side of the light distribution lens 12 are lit. In this embodiment, the floodlight section is located on both sides of the focusing section to form a wider light emission angle. This step enables wide-range lighting coverage. Specifically, the main control board controls the LED channels corresponding to the floodlight area, which can be lit symmetrically on both sides simultaneously, or grouped and lit as needed. This step enhances the visibility range of near-to-mid-distance areas, reduces overly bright centers and dark edges, and improves the effectiveness of inspection and area observation.

[0061] When the target lighting mode is the simultaneous activation of spotlight and floodlight, the LED beads in the areas corresponding to the spotlight and floodlight on the side of the control lens 12 are lit up simultaneously. In this embodiment, the simultaneous activation of the spotlight and floodlight is a composite light emission mode, balancing center penetration and peripheral coverage. This step transforms the composite lighting requirements in mid-range, low-brightness environments into the simultaneous control of multiple emitting areas. Specifically, the main control board simultaneously activates the spotlight and floodlight channels and can set different drive current ratios, such as slightly higher at the center and slightly lower at the sides, to optimize the overall appearance. This step improves the lighting adaptability in complex work scenarios and reduces the need for operators to repeatedly switch between different modes.

[0062] When the target illumination mode is uniform light mode, the LED beads in the corresponding area on the side of the uniform light cover 13 are turned on, and the LED beads in the corresponding area on the side of the light distribution lens 12 are turned off. In this embodiment, the area corresponding to the side of the light-diffusing mask 13 is a light-emitting area used to form soft and uniform illumination. This step enables low-glare illumination during close-range precision work and avoids glare caused by the superposition of light emitted from the side of the light-distributing lens 12. Specifically, the main control board closes the channel on the side of the light-distributing lens 12, opens the channel of the light-diffusing area, and can control the brightness using a lower current or a specific dimming curve. This step significantly improves the comfort of close-range operation and the ability to recognize details, while reducing strong light reflection and visual fatigue.

[0063] When the target lighting mode is warning mode, the LED beads in the preset warning light area are controlled to flash according to the preset warning frequency and duty cycle.

[0064] In this embodiment, the warning illumination area is a dedicated warning display area on the light panel 11, which can overlap with or be set independently of the normal lighting area. The warning frequency and duty cycle are parameters describing the flashing rhythm. This step presents the warning mode with a more visually striking flashing pattern, highlighting the abnormal state. Specifically, the main control board calls the warning mode parameters and outputs periodic switching control or PWM flashing control signals to the LED driver module. The frequency and duty cycle can be executed according to preset values ​​or adjusted according to the risk level. This step enhances the visibility and recognizability of the warning, enabling the light fixture to not only illuminate in abnormal environments but also serve as an active reminder.

[0065] Please see Figures 1 to 3 In one embodiment, the lamp body assembly 2 and the lamp head assembly 1 are hinged via a rotating hole and a rotating shaft; the explosion-proof portable lamp further includes a magnetic encoder, which includes a magnetic rotor and a magnetic sensor, the magnetic rotor and the magnetic sensor being respectively disposed at the hinge positions corresponding to the rotating hole and the rotating shaft; the step of acquiring environmental change information and determining the target lighting mode recommendation result based on the environmental change information further includes: Obtain the hinge angle information of lamp head assembly 1 relative to lamp body assembly 2; In this embodiment, the hinge angle information is the rotation angle parameter of the lamp head relative to the lamp body, which can be detected by a magnetic encoder. The magnetic rotor and magnetic sensor in the magnetic encoder are respectively arranged at the corresponding hinge positions, generating a change in the magnetic field through relative rotation and outputting an angle signal. This step obtains information related to the current illumination direction of the lamp, providing a geometric basis for pattern recommendation correction. It is understandable that under the same distance and brightness conditions, different lamp head orientations may result in different actual lighting needs. Specifically, the main control board reads the magnetic sensor output signal, converts it into a hinge angle value through a lookup table or calibration curve, and can filter the continuously sampled values ​​to obtain stable angle information. This step allows pattern recommendation to consider not only environmental parameters but also the lamp's posture, improving the consistency between the recommended results and actual usage actions.

[0066] The target lighting pattern recommendation result is corrected based on the hinge angle information and the environmental change information; In this embodiment, correction refers to adjusting the priority or reselecting the mode based on the basic recommendation results and the orientation of the lamp head. This enhances the scene perception capability of the mode recommendation and avoids inaccuracies caused by judging solely based on distance and brightness. It is understood that environmental change information reflects external conditions, while hinge angle information reflects the operator's current lighting intention; combining the two yields a more reasonable recommendation. Specifically, the main control board can first generate basic mode recommendations, then read angle ranges and apply correction rules, such as increasing the priority of uniform lighting in one angle range and increasing the priority of focused lighting in another. The corrected result then enters the voice prompt process. This step improves recommendation accuracy and human-machine consistency, reducing the probability of the operator repeatedly changing modes.

[0067] When the hinge angle information indicates that the lamp head is facing a close-range working surface, the recommended priority of floodlight mode or uniform light mode is increased. In this embodiment, the near-field working surface can be understood as the state where the lamp head is pointing downwards or towards the nearby operating area. This step can infer from the lamp head posture that the operator may be performing near-field work, thereby prioritizing the recommendation of modes more suitable for the near field. Specifically, the main control board can set angle range thresholds. For example, when the hinge angle falls into the downward or near-field range, the priority of the floodlight or uniform light mode is increased by one level, and then combined with distance and brightness conditions for a comprehensive judgment. This step makes the lamp control more in line with the operator's movement habits, improving the naturalness and accuracy of mode recommendations.

[0068] When the hinge angle information indicates that the lamp head is facing a distant area, the recommended priority of the focusing mode is increased.

[0069] In this embodiment, the distant area corresponds to the lamp head being held horizontally or facing forward. This step enhances the recommended focusing mode when the lamp head is clearly facing away from the distance, meeting the needs of long-distance recognition. Specifically, the main control board increases the priority weight of the focusing mode when the angle enters the distant range, giving priority to focusing suggestions even when brightness and other conditions are at the boundary. This step improves the adaptability of long-distance lighting, reduces mode instability caused by fluctuations in environmental parameters, and enhances the actual user experience.

[0070] Please see Figures 1 to 3 In one embodiment, the explosion-proof portable light further includes an indicator light, which is disposed on the light body assembly 2; the step of outputting a voice prompt based on the target lighting mode recommendation result, and if a mode confirmation signal is obtained within a second preset time, controlling the light panel 11 to light up or flash the corresponding area according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is obtained within the second preset time, the step of maintaining the lighting mode at startup further includes: While outputting voice prompts, the indicator light is turned on or flashed to prompt the operator to confirm the mode. In this embodiment, the indicator light is a visual cue component mounted on the lamp assembly 2, which can be used for status feedback. This step adds a visual cue channel in addition to the voice prompt, forming a dual-channel interactive feedback. Specifically, the main control board controls the indicator light to remain constantly lit or flashing while triggering the voice broadcast, and maintains this state synchronously with the mode confirmation window. This step improves the reliability of the prompt; even if the operator does not clearly hear the voice, they can still determine that they have entered the mode confirmation process through the indicator light.

[0071] The lighting status of the indicator light is controlled according to the preset indication rules corresponding to the current target lighting mode; Different lighting modes correspond to different indicator light flashing rhythms or number of times the lights are on, so that operators can quickly identify the current recommended mode in dark environments; In this embodiment, the preset indication rules are the indicator light display encoding rules corresponding to different modes, such as the number of flashes, flashing rhythm, or constant illumination duration. This step allows the indicator light to not only indicate that confirmation is in progress but also convey the currently recommended mode category. Specifically, the main control board retrieves the corresponding indicator light control parameters from the rule table according to the target mode and executes them, such as single flash in spotlight mode, double flash in floodlight mode, and slow flash in uniform light mode. This step improves mode recognition in dark or high-noise environments, allowing voice and visual cues to complement each other. Specifically, different flashing sequences can be generated by the main control board's timer and played in a loop within the confirmation window. This step enhances the environmental adaptability of the interaction, enabling pattern recognition and confirmation to be completed even in noisy, windy, or protective gear-wearing conditions.

[0072] When the current target lighting mode is warning mode, the indicator light is controlled to emit a warning indication with a high-frequency flashing rhythm.

[0073] In this embodiment, the main control board switches the indicator light to a high-frequency flashing parameter, which can be output synchronously with the voice risk prompt. This step creates a triple warning system consisting of voice, main lighting, and indicator light, improving perceptibility and response speed in abnormal environments.

[0074] Please see Figures 1 to 3 In one embodiment, the method further includes: The system continuously samples environmental change information and determines whether the magnitude of environmental change within adjacent sampling periods exceeds a preset change threshold; wherein the environmental change information includes at least one of environmental brightness information, target distance information, and environmental risk information. In this embodiment, continuous sampling refers to periodically acquiring environmental data during operation. The magnitude of environmental change is the amount of change between adjacent sampling results, reflecting the speed or intensity of environmental change. A preset change threshold is used to determine whether the mode recommendation needs to be updated. It is understood that handheld explosion-proof lights are mainly used in scenarios where the working environment changes, therefore the lighting requirements should also be updated accordingly, but frequent switching due to minor fluctuations should be avoided, thus requiring a change threshold. Specifically, the main control board maintains the sampling cache, calculates brightness differences, distance differences, or changes in risk status, and compares them with the corresponding thresholds. A single-variable threshold or a weighted comprehensive threshold can be used. This step enables real-time mode recommendation while suppressing meaningless updates through threshold judgment, maintaining stable lighting.

[0075] When the preset change threshold is exceeded, the voice prompt update process is triggered to regenerate the target lighting mode recommendation result and output new voice prompt information; In this embodiment, the voice prompt update process refers to re-executing the process of environmental assessment, mode recommendation, and voice broadcast. This step can proactively remind the operator to update the lighting mode when the environment changes significantly.

[0076] Specifically, after the main control board detects a change exceeding the threshold, it calls the mode recommendation module to recalculate the target mode, then triggers the voice broadcast module to output a new prompt and opens a new mode confirmation window. This process ensures that the lighting fixtures continuously adapt to dynamic operating conditions, reducing the operator's burden of manual observation and switching.

[0077] When environmental risk information meets the preset warning trigger conditions, the voice prompt update process of the warning mode will be triggered first. In this embodiment, environmental risk information can come from gas concentration, abnormal temperature, or other risk sensor inputs. Preset warning trigger conditions are the criteria for entering the warning process. This step sets risk events as the highest priority trigger source in the dynamic update process. It is understood that risk events are more important than lighting comfort; a detected risk should immediately initiate the warning notification process without waiting for the normal mode update sequence. Specifically, the main control board prioritizes risk condition checks during continuous sampling. Once met, it directly invokes the recommended warning mode and warning voice broadcast. If necessary, the current normal mode confirmation process can be interrupted. This step improves the response speed to abnormal operating conditions and enhances the system's safety attributes.

[0078] When the preset change threshold is not exceeded and the preset warning trigger condition is not met, the current lighting mode is maintained to reduce operational interference caused by frequent switching.

[0079] Specifically, if the main control board determines that the update conditions are not met, it will continue to maintain the current mode driving parameters and may only update the sampling cache without triggering any prompts. This step improves system stability and user comfort, and reduces noise and visual interference caused by frequent prompts.

[0080] In one embodiment, the method further includes: After switching to the target lighting mode, record the current environmental changes, the target lighting mode, and the operator's confirmation results; In this embodiment, the operator confirmation result refers to the mode selection ultimately accepted or specified by the operator. This step establishes a historical mapping between the environment and mode selection, providing a basis for rapid recommendations in similar scenarios. It is understood that the same operator often has stable preferences in similar environments, and recording history can improve the accuracy and efficiency of subsequent recommendations. Specifically, after each mode confirmation, the main control board writes the environmental parameters, recommended mode, and final confirmed mode into local memory, which can be managed using a timestamp and record item method. If necessary, the storage quantity can be limited and an overwrite strategy can be adopted. This step enables the system to have simple memory capabilities, gradually aligning with actual usage habits and improving its level of intelligence.

[0081] When similar environmental change information is detected in the future, the lighting mode corresponding to the historical confirmation result is used as the target lighting mode recommendation result, and a voice prompt message is output for confirmation. In this embodiment, similar environmental change information refers to environmental states that are close to historical records within a threshold range. This step reduces re-judgment and trial-and-error in repetitive scenarios, prioritizing the use of previously confirmed effective patterns. It is understood that historical confirmation results reflect actual operational preferences and are generally closer to actual usage needs than single rule judgments. Specifically, before generating basic recommendations, the main control board performs historical matching. If a match is successful, it reads the corresponding historical confirmation pattern as the priority recommendation, then informs the operator via voice prompts and awaits confirmation. This step improves recommendation hit rate and interaction efficiency, reducing repetitive adjustments by the operator.

[0082] Among them, similar environmental change information is determined at least based on threshold range matching of environmental brightness information, target distance information and environmental risk information; In this embodiment, threshold interval matching refers to comparing the current sampled value with historical records; if the difference falls within a preset tolerance range, the values ​​are considered similar. This step clarifies the criteria for determining similar environments, ensuring the implementation of historical recall logic. Specifically, the main control board can set brightness tolerance, distance tolerance, and risk status matching rules respectively, comparing or weighting the three types of information item by item, and determining similarity if the conditions are met. This step improves the stability and practicality of the historical memory mechanism, preventing the failure to hit historical records due to minor fluctuations.

[0083] When historical confirmation results correspond to an alert mode and the current environmental risk information again meets the corresponding alert triggering conditions, the alert mode is recommended first.

[0084] Specifically, after a successful historical match, the main control board first checks whether the historical confirmation mode is in alert mode, and simultaneously verifies whether the current risk conditions meet the corresponding trigger conditions. If they do, it directly sets the alert mode as the preferred recommendation and broadcasts a risk warning. This step further enhances the system's ability to respond quickly to risky environments and improves proactive safety in explosion-proof scenarios.

[0085] In summary, the control method for the explosion-proof portable lamp provided by this embodiment of the invention includes a lamp head assembly 1 and a lamp body assembly 2, which are hinged together. The lamp head assembly 1 includes a lamp plate 11, a light-distributing lens 12, and a light-diffusing cover 13. The light-distributing lens 12 can form focused and / or floodlight output, and the light-diffusing cover 13 can form uniform light output. The method includes: acquiring a first start signal and outputting a voice prompt to indicate whether to turn on the lighting; if a second start signal is acquired within a first preset time, driving the lamp plate 11 to illuminate; if no second start signal is acquired within the first preset time, driving the lamp plate 11 to illuminate. If a start signal is received, the system returns to the state of receiving the first start signal; environmental change information is acquired, and a target lighting mode recommendation result is determined based on the environmental change information; wherein, the target lighting mode includes spotlight mode, floodlight mode, spotlight and floodlight simultaneously on mode, uniform lighting mode, and warning mode; a voice prompt is output based on the target lighting mode recommendation result; if a mode confirmation signal is received within a second preset time, the corresponding area of ​​the light panel 11 is controlled to light up or flash according to the mode confirmation signal to switch the lighting mode; if no mode confirmation signal is received within the second preset time, the lighting mode at startup is maintained. The explosion-proof portable lamp of the present invention has a hinged structure of lamp head assembly 1 and lamp body assembly 2, and a lamp plate 11, a light distribution lens 12 and a light dome 13 are provided on the lamp head assembly 1, so that the lamp naturally has multiple light output bases such as focusing, floodlighting and light domeing, and is no longer limited to a single lighting mode. On this basis, by acquiring environmental change information and determining the target lighting mode recommendation result accordingly, a direct correspondence is established between the external environmental state and the lighting mode selection, so that lighting control no longer depends on the operator's fixed habits or single manual switching. Furthermore, the recommended result is output through voice prompts and a mode confirmation signal is received within a preset time to realize the linkage control of environmental perception, mode recommendation and human-machine interaction confirmation. While ensuring the prevention of accidental touch and the safety of use, the lamp plate 11 is driven to light up or flash the corresponding area to switch to the matching mode, so that the explosion-proof portable lamp can adjust the lighting mode in a timely manner according to the change of the working environment, solving the problem that the existing explosion-proof portable lamps have relatively single lighting modes and cannot adapt to lighting needs with changes in the environment.
