BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 FIG. is a schematic flow chart of a control method for a mobile lighting device provided by an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0028] Existing head-mounted lamps usually only have the function of manually controlling the brightness and color temperature of the mobile lighting device. In order to enable the mobile lighting device to have a long-distance illumination ability, the lighting unit of the mobile lighting device usually adopts a spotlight design, resulting in the need for repeated manual adjustments when the user needs to adjust the light source output of the mobile lighting device according to the actual lighting environment, which causes inconvenience in use.

[0029] Based on this, the present application provides an illumination control method and a mobile illumination device to automatically adjust the proportion of illumination types according to the distance data of the target user and automatically adjust the illumination brightness according to the ambient brightness, thereby improving the user experience.

[0030] As Figure 1 shown, Figure 1 is a schematic flow chart of a control method for a mobile illumination device provided by an embodiment of the present application. The control method is used to control an illumination unit including at least a first type of light source and a second type of light source when the mobile illumination device is turned on to achieve illumination adjustment.

[0031] It can be understood that the mobile illumination device in the embodiment of the present application has a first type of light source and a second type of light source that can be independently controlled respectively. The light projected by the first type of light source forms a floodlight light pattern, and the light projected by the second type of light source forms a spotlight light pattern. The floodlight light pattern has dispersed light, evenly irradiates in all directions, forms a large-area uniform illumination, the overall light is soft, and the brightness is evenly distributed, avoiding local overbrightness or overdarkness. The spotlight light pattern has concentrated light, forms a bright central light spot, the beam boundary is clear, can focus the light in a smaller area, the central light spot has a high brightness, and the illumination intensity is large.

[0032] It should be noted that the embodiment of the present application does not limit the arrangement manner of the first type of light source and the second type of light source. It can be a concentric setting with the spotlight area in the center and the floodlight area on the outside, or a side-by-side setting with the spotlight area and the floodlight area adjacent to each other on the left and right.

[0033] It can be understood that several mutually independent light-emitting lamp beads are provided in both the first type of light source and the second type of light source, so that the control board can change the projection intensity and projection color temperature of the first type of light source and the second type of light source by controlling the number of energized lamp beads and the magnitude of the current, thereby changing the proportion of the illumination parameters of the two light sources.

[0034] The above introduces the architecture of the embodiment of the present application. Taking the illumination parameter as the illumination intensity as an example, the illumination control method is specifically described as follows. The control method includes:

[0035] S1. When controlling the illumination parameters of each type of light source in the illumination unit of the mobile illumination device according to a preset ratio, obtain environmental parameters, where the environmental parameters include environmental brightness information and the real-time distance value between the mobile illumination device and the target object;

[0036] In this embodiment, the real-time distance value between the mobile illumination device and the target object is continuously obtained through a distance sensor. The distance sensor can be an infrared sensor, a laser sensor, an ultrasonic radar, a millimeter-wave radar, etc. When obtaining the real-time distance value, only the real-time distance value of the object closest in distance is obtained as the subsequent calculation basis.

[0037] In this embodiment, in the initial state, the illumination parameter ratios of various types of light sources are fixed preset ratios. This preset ratio does not directly mean that the sum of the luminous fluxes of various types of light sources is equal to 100%, but rather refers to the sum of the ratios of the illumination parameters of various types of light sources. Exemplarily, if the preset ratio is 100%, the ratio of the illumination parameters of the first type of light source and the second type of light source in the initial state is 50%:50%. To ensure the constancy of the total illumination parameter, when increasing the illumination parameter of one type of light source, the illumination parameter of the other type of light source is simultaneously reduced. For example, when the illumination parameter of the first type of light source is adjusted to 75%, the illumination parameter of the second type of light source is 25%.

[0038] It can be understood that the values of the actual illumination parameters of various types of light sources are set according to the application scenario. The total illumination parameter is also set according to requirements. By adjusting the proportions of the first type of light source and the second type of light source in the total illumination parameter, automatic adjustment of the mobile lighting device is achieved.

[0039] In some other embodiments, a third type of light source, a fourth type of light source, etc. are also included, and so on. The sum of the illumination parameters of multiple types of light sources is still equal to 100%. By obtaining the real-time distance value between the mobile lighting device and the target object, the proportions of various types of light sources are adjusted.

[0040] S2. Match the corresponding target illumination condition parameters according to the real-time distance value, and adjust the illumination parameters of various types of light sources according to the target illumination condition parameters, so as to adjust the illumination parameter of the target type of light source to the set proportion;

[0041] In this embodiment, the target type of light source is the first type of light source, that is, the floodlight source. When the two parties gradually approach, increase the proportion of the illumination parameter of the first type of light source to reach the preset proportion. At the same time, to ensure that the total illumination parameter of the lighting unit is still the preset ratio, it is necessary to reduce the illumination parameter of the other type of light source, that is, the second type of light source, to avoid the spotlight source still shining on the face of the oncoming user at close range. By adjusting the target type of light source in multiple types of light sources to reach the preset proportion, the light of the mobile lighting device can be made softer while ensuring that the overall illumination parameter remains unchanged.

[0042] In some embodiments, when the real-time distance value is lower than the set threshold, it is determined whether the mobile lighting device is in the automatic control mode that can automatically adjust the lighting parameters; if so, it is determined that the distance between the mobile lighting device and the target object is too close, and the real-time distance value is input into the preset comparison range for comparison, otherwise the mobile lighting device does not perform any action.

[0043] S3. Match the corresponding illumination brightness according to the ambient brightness information, and adjust the illumination unit to the set brightness;

[0044] In this embodiment, when matching the corresponding illumination brightness according to the ambient brightness information, it can be a pre-set brightness table. By obtaining the illuminance unit lux corresponding to the illumination brightness, the output brightness corresponding to this unit is obtained to control the illumination unit; it can also be by setting an adjustment function. By inputting the ambient illuminance value, the matching output brightness is calculated to adjust the illumination unit. Specifically, when the ambient brightness increases, the illumination brightness of the illumination unit is reduced, and when the ambient brightness weakens, the illumination brightness of the illumination unit is increased.

[0045] In some embodiments, the matching of the corresponding target illumination condition parameters according to the real-time distance value includes:

[0046] S2a. When the real-time distance value between the mobile lighting device and the target object is less than or equal to a preset first threshold, adjust the illumination parameter ratio of the target type light source to a preset first ratio;

[0047] It can be understood that when the real-time distance value between the mobile lighting device and the target object is less than or equal to the first threshold, it can be determined that the distance between the target object and the wearer of the mobile lighting device is too close. At close range, by completely using the first type of light source to ensure wide-area illumination, while avoiding the sudden illumination of the second type of light source on the face of the oncoming user, ensuring the illumination effect while guaranteeing the experience of both parties during the meeting, and improving the convenience of communication between users at close range.

[0048] S2b. When the real-time distance value is within a preset comparison range between the preset first threshold and the second threshold, calculate the relative position ratio of the real-time distance value within the preset comparison range, query the illumination parameter table according to the relative position ratio, obtain the target illumination condition parameters corresponding to the relative position ratio, and adjust the illumination parameters of each type of light source according to the target illumination condition parameters to adjust the illumination parameter of the target type light source to the preset ratio;

[0049] It can be understood that in the actual scenario, the distance of the target object will gradually move away or gradually approach. Therefore, the mobile lighting device needs to obtain the distance value of the target object in real time, so as to control the ratio of the illumination parameters of the target type light source and the second type of light source, and adjust the illumination parameter ratio of each type of light source at all times in the form of a function curve or stage control within the preset comparison range.

[0050] S2c. When the real-time distance value is greater than or equal to the second threshold, adjust the illumination parameters of each type of light source in the illumination unit of the mobile lighting device to a second ratio.

[0051] It can be understood that upper and lower limits for increasing and decreasing the target type light source and the second type light source are set in the second ratio. When the distance data is greater than or equal to the second threshold, it can be determined that the oncoming object (or user) has moved away from the mobile lighting device. At this time, the target type light source gradually decreases and the second type light source gradually increases until the light parameter ratios of the two light sources reach a preset second ratio. The second ratio can be that the light parameter ratios of the first type light source and the second type light source each account for half, enabling the mobile lighting device to take into account both the lighting range and the lighting distance during normal use, and making the transition of the target type light source and the second type light source above the second threshold smoother within the preset comparison range.

[0052] In some embodiments, the control method further includes: adjusting the light parameters of the target type light source and the second type light source, which also includes the number of lighting elements of the corresponding type of light source turned on and controlling the power of the lighting elements of the corresponding type of light source. The number of lighting elements turned on can be set according to a preset rule. Exemplarily, when the light ratio of the target type light source increases, the lighting elements in the target type light source array are gradually turned on (for example, 1 lighting element is turned on for every 10% increase in the ratio). Controlling the power of the lighting elements can adopt PWM dimming technology. By adjusting the proportionality coefficient k, the drive current of the light source is adjusted. By combining the control of the number and power of the light sources, the energy efficiency ratio is increased by more than 20% to avoid overloading of a single light source. It can be understood that in step S3, when matching the corresponding lighting brightness according to the ambient brightness information and adjusting the lighting part, the lighting brightness of the lighting part can also be adjusted by changing the number of lighting elements turned on and the power of the lighting elements.

[0053] In some embodiments, the preset comparison range where the real-time distance value is between the first threshold and the second threshold includes:

[0054] Mapping the real-time distance value to an adjustment proportionality coefficient k ranging from 0 to 1 within the preset comparison range;

[0055] Controlling the light parameter ratio of the target type light source according to the adjustment proportionality coefficient k.

[0056] Specifically, let the two endpoints of the preset comparison distance be the first threshold d min and the second threshold d max , and the adjustment proportionality coefficient is obtained by linear interpolation Let the intensity P 聚光 of the second type light source (spotlight) = k, and the intensity P 泛光 of the target type light source (floodlight) = 1 - k. Exemplarily, if the preset comparison range is 3m to 5m, it can be obtained that:

[0057] When the distance data d = 3.5m, At this time, the lighting parameter of the spotlight source is 25%, and the lighting parameter of the floodlight source is 75%; when the distance data d = 4.5m, At this time, the lighting parameter of the spotlight source is 75%, and the lighting parameter of the floodlight source is 25%.

[0058] In some other embodiments, the preset comparison range can be sequentially divided into several intervals, and the lighting parameter ratios of the corresponding target type light source and the second type light source are set for each interval. When the distance data of the target object passes through different intervals, different lighting parameter ratios are output to control the lighting unit, so that the lighting parameters of the first and second type light sources change in a stepped manner.

[0059] In some other embodiments of the present application, the second type light source is provided with an intensity upper limit, so that after the distance data of the target object exceeds the preset comparison distance, a certain proportion of the floodlight source is still retained. When there is no nearby user in front of the user and the mobile lighting device needs to be used normally, the second type light source provides a lighting effect at a relatively long distance, and the target type light source with a lower lighting parameter ratio still provides a certain lighting effect for the surrounding environment.

[0060] In some embodiments, the adjustment ratio coefficient is calculated by the linear interpolation method or the exponential smoothing algorithm, and the lighting parameter changes linearly or exponentially. When the lighting parameter changes linearly, the adjustment ratio coefficient k is a linear function. If it is necessary to adapt to the human eye perception or specific scene requirements, the adjustment ratio coefficient k can be mapped to a non-linear function (such as an exponential function or a logarithmic function) to meet more diverse lighting control requirements.

[0061] In some embodiments, when the real-time distance value is within the preset comparison range between the first threshold and the second threshold, the lighting color temperature table is queried according to the relative position ratio, and the target projection color temperature corresponding to the relative position ratio is obtained, and the lighting unit is adjusted according to the target projection color temperature.

[0062] It can be understood that the adjustment principle of the projection color temperature is roughly the same as that of the lighting parameter ratio. Within the preset comparison range, a fixed color temperature change range is set, such as 3000K to 6000K, to match the first type light source and the second type light source with continuously changing lighting parameter ratios. For the floodlight source, the low-color-temperature lighting is softer, and for the spotlight source, the high-color-temperature visual experience is brighter. When the real-time distance value between the target object and the mobile lighting device decreases within the preset comparison range, the color temperature also linearly decreases within the fixed color temperature change range.

[0063] In some other embodiments, the projected color temperature of the lighting unit is also controlled in a phased manner. The preset comparison range is sequentially divided into several intervals, and a corresponding projected color temperature of the lighting unit is set for each interval. When the distance data of the target object passes through different intervals, different projected color temperatures are output to control the lighting unit, so that the projected color temperature changes in a stepped manner.

[0064] In some embodiments, the proportion of the light parameters changes smoothly when passing through the first threshold and the second threshold. Specifically, a transition space with a certain distance (such as 30 cm) is set at the first threshold and the second threshold. When the light parameters change at the boundary of the preset comparison range, the S-shaped curve is used to gradually change the light proportion to avoid the problem of light jitter. If the distance data fluctuates beyond the threshold within 0.5 seconds, the distance data is frozen and adjusted until the data is stable.

[0065] In some embodiments, when the real-time distance value is less than the set threshold, the overall light intensity of the lighting unit is linearly reduced. The lighting unit refers to the first type of light source and the second type of light source that are currently emitting light in the current lighting unit. When reducing the overall light intensity, the light parameters of the two types of light sources are reduced simultaneously through a linear function, that is, the overall light parameters are reduced. When reducing the overall light parameters, the ratio of the light parameters between the first type of light source and the second type of light source remains unchanged.

[0066] In some other embodiments, the range of reducing the overall light intensity is larger than the preset comparison range. When meeting an oncoming user at a short distance, first reduce the overall light intensity of the lighting unit. As the distance between the mobile lighting device and the oncoming user gets closer, and the distance data enters the preset comparison range, then start to adjust the proportion of the target type of light source and the second type of light source, and gradually reduce the overly strong and overly concentrated light beam from irradiating the face of the oncoming user in two stages.

[0067] In some embodiments, when the mobile lighting device is in the on state, when it recognizes the recognition signal sent by the target object for matching, it controls the mobile lighting device to make adjustments; otherwise, it maintains the current projection state. It judges whether the recognition signal exists in the matching information library. If so, it controls the mobile lighting device to make adjustments; otherwise, it maintains the current projection state. By judging whether the oncoming mobile lighting device is its own product, if so, it executes the corresponding brightness adjustment plan. When the distance between the two reaches a certain limit (below the set threshold), it directly starts to obtain the recognition signal and execute the corresponding matching process. Thereby ensuring that the target object is only a mobile lighting device with the same function and the wearer, avoiding the change of the mobile lighting device being affected by the environment, and not triggering the control method of the mobile lighting device when approaching an obstacle at a short distance, ensuring that the mobile lighting device is only adjusted and controlled when pedestrians meet.

[0068] In summary, through the above method, the present application obtains the environmental parameters of the lighting environment of the mobile lighting device, adaptively adjusts the lighting parameters of the mobile lighting device, obtains the real-time distance value between the mobile lighting device and the target object, and determines that the distance between the mobile lighting device and the target object is too close when the real-time distance value is too small. The corresponding target lighting condition parameters are matched according to the real-time distance value, and the lighting parameters of various types of light sources are adjusted according to the target lighting condition parameters to adjust the lighting parameters of the target type light source to a set proportion. At the same time, the corresponding lighting brightness is matched according to the environmental brightness information, and the lighting unit is adjusted to the set brightness, further adjusting the mobile lighting device to automatically reach the set brightness that conforms to the lighting environment without manual operation by the user, improving the convenience of use.

[0069] An embodiment of the present application also proposes a mobile lighting device, which includes a lighting unit and a lighting controller. The lighting unit includes a spotlight source and a floodlight source. The lighting controller is used to control the lighting unit to execute the control method described in any one of the above.

[0070] The beneficial effects of the mobile lighting device have been fully described in the above control method and will not be repeated here.

[0071] It should be understood that the application of the present application is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present application.
