[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Figure 1 A schematic diagram of a smart lamp is provided for an embodiment of the present invention. Figure 1 , including: a control module 110, a plurality of light-emitting modules 120, a lens module 130, an adjustment module 140 and a scene acquisition module 150;

[0052] The light emitting modules 120 are arranged in an array to form a light emitting area;

[0053] In the light-emitting area, the adjustment module 140 is arranged on the same side of the light-emitting path of the light-emitting module 120; the adjustment module 140 corresponds to the axis of the light-emitting path of the light-emitting module 120, and the lens module 130 is arranged on the adjustment module 140; the control module 110 is respectively connected to the adjustment module 140 and the scene acquisition module 150; the scene acquisition module 150 is used to obtain the current application scene of the user and output the current application scene to the control module 110, and the control module 110 selects the adjustment strategy of the lamp according to the current application scene;

[0054] The control module 110 is used to output a first control signal to the adjustment module 140 according to the adjustment strategy, and the adjustment module 140 is used to adjust the distance between the lens module 130 and the light-emitting module 120 in the light-emitting area according to the first control signal to adjust the lighting range output by the light-emitting module 120 to the target area.

[0055] Specifically, the light emitting module 120 is a light source output module, and the light emitting module 120 may be an LED light emitting unit, wherein the number of LED light emitting units in the light emitting module 120 may be one or more, that is, the light emitting module 120 may be composed of one LED light emitting unit, and the light emitting module 120 may be composed of multiple LED light emitting units, and the number of LED light emitting units in the light emitting module 120 may be set according to the requirements of the light emitting power, and is not limited here. The light emitting modules 120 are arranged in an array to obtain a light emitting area of ​​a certain area, and the maximum brightness requirement of the light emitting area may be designed and adjusted according to the number of light emitting modules 120 set or the number of LED light emitting units in the light emitting module 120. Exemplarily, the array arrangement method may be designed according to the shape requirements of the light emitting area, for example, the array method may be a matrix array, a circular array, a regular polygon array, etc., and is not specifically limited here.

[0056] The adjustment module 140 is arranged on the same side of the light emitting path of the light emitting module 120, and the lens module 130 is arranged on the adjustment module 140. The lens module 130 can correspond to the axis line of the light emitting path of each group of the light emitting modules 120, that is, the light emitting path of the light emitting module 120 passes through the lens module 130. The lens module 130 changes the light transmission path, which can be used to diverge light and focus light. Figure 2 This is a schematic diagram of the path of light passing through the lens module, see Figure 2 , after the light passes through the lens module 130, divergent light and focused light can be generated. Exemplarily, the lens module 130 can be an optical system composed of a single lens, or an optical system composed of a lens array composed of multiple lenses. No specific limitation is made here. The lens module 130 can achieve the shaping of the light. Therefore, it can be seen that when the lamp irradiates to the height of the target area, by adjusting the distance between the lens module 130 and the light-emitting module 120, the illumination range of the light irradiating to the target area can be changed. For ease of understanding, for example, the lamp can be a desk lamp. Assume that the height of the desk lamp from the desktop is 45 cm, and the desktop is the target area for illumination. Figure 3This is a light distribution diagram of an embodiment of the present invention when a lens module is not provided, wherein the X-axis is marked as the size distribution in the X-axis direction on the plane, and the scales from left to right are marked as 750, 600, 400, 200, 0, -200, -400, -600, -750, in mm. The Y-axis is marked as the size distribution in the Y-axis direction on the plane, and the scales from top to bottom are marked as 750, 700, 600, 500, 400, 300, 200, 100, 0, -100, -200, -300, -400, -500, -600, -700, -750, in mm. The left side indicates the illumination distribution from black to white, with scales of 0, 0.09, 0.18, 0.27, 0.36, 0.45, 0.54, 0.63, 0.72, 0.81, 0.9, 0.99, 1.08, 1.17, 1.26, 1.35, 1.44, 1.53, 1.62, 1.71, 1.8, in Lux. In the graph, the ordinate is illumination, from 0-1.8, with intervals of 0.1, in Lux, and the abscissa is the length, from -800-800, with intervals of 100, in mm. The blue curve is the distribution curve of illumination along the X-axis with the plane size, and the green curve is the distribution curve of illumination along the Y-axis with the plane size. According to the light distribution diagram, it can be seen that the highest illumination is 1.77 Lux, and the illumination range is relatively dispersed. Figure 4This is a light distribution diagram when a lens module is set according to an embodiment of the present invention, wherein the X-axis is marked as the size distribution in the X-axis direction on the plane, and the scales from left to right are marked as 700, 600, 500, 400, 300, 200, 100, 0, -100, -200, -300, -400, -500, -600, -700, in mm. The Y-axis is marked as the size distribution in the Y-axis direction on the plane, and the scales from top to bottom are marked as 750, 700, 600, 500, 400, 300, 200, 100, 0, -100, -200, -300, -400, -500, -600, -700, -750, in mm. The left side indicates the illumination distribution from black to white, with scales of 0, 0.9, 1.8, 2.7, 3.6, 4.5, 5.4, 6.3, 7.2, 8.1, 9, 9.9, 10.8, 11.7, 12.6, 13.5, 14.4, 15.3, 16.2, 17.1, and 18, in Lux. In the graph, the ordinate is illumination, from 0 to 18, with intervals of 0.5, in Lux, and the abscissa is the length, from -800 to 800, with intervals of 100, in mm. The blue curve is the distribution curve of illumination along the X-axis with the plane size, and the green curve is the distribution curve of illumination along the Y-axis with the plane size. According to the light distribution diagram, it can be seen that when the light-emitting module 120 is in telephoto, the image of the LED will be projected on the desktop, with a maximum illumination of 17.59 Lux, and a relatively concentrated illumination range. Figure 5This is another light distribution diagram when the lens module is set according to an embodiment of the present invention, wherein the X-axis is marked as the size distribution in the X-axis direction on the plane, and the scales from left to right are marked as 750, 700, 600, 500, 400, 300, 200, 100, 0, -100, -200, -300, -400, -500, -600, -700, -750, in mm. The Y-axis is marked as the size distribution in the Y-axis direction on the plane, and the scales from top to bottom are marked as 750, 700, 600, 500, 400, 300, 200, 100, 0, -100, -200, -300, -400, -500, -600, -700, -750, in mm. The left side indicates the illumination distribution from black to white, with the scales of 0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.75, 4, 4.25, 4.5, 4.75, 5, in Lux. In the graph, the ordinate is the illumination, from 0-5, with an interval of 0.2, in Lux, and the abscissa is the length, from -800-800, with an interval of 100, in mm. The blue curve is the distribution curve of the illumination along the X-axis with the plane size, and the green curve is the distribution curve of the illumination along the Y-axis with the plane size. By adjusting the spacing between the light-emitting module 120 and the lens module 130, a softer light distribution diagram can be obtained, with a maximum illumination of 4.9 Lux and an overall luminous flux of 0.5138 lm. In combination with the above light pattern diagram, it can be seen that when the light emitting module 120 is at a far focus, an image of the LED will be projected on the desktop, and when the light emitting module 120 is at one focal length, the light will appear divergent. By combining the focal length formula, it can be obtained through simulation that if a larger lighting range or a specific lighting range is required, the distance between the lens module 130 and the light emitting module 120 can be adjusted to obtain it. That is to say, the distance between the lens module 130 and the light emitting module 120 has a certain mapping relationship with the lighting range.

[0057] Therefore, the control module 110 sends a first control signal, and the control adjustment module 140 adjusts the distance between the lens module 130 and the light emitting module 120, so as to adjust the lighting range. The first control signal here can be a current, a voltage or a pulse width modulation signal after digital processing. The first control signal can be generated by a custom manual input, so as to meet the user's custom adjustment of the lighting range. The first control signal can also be automatically generated, and the intelligent lamp is also provided with a scene acquisition module 150, and the scene acquisition module 150 can be configured with a corresponding image acquisition unit. The user's current action characteristics can be obtained by using image acquisition technology, and the user's current application scenario can be inferred by combining image processing and artificial intelligence control. For example, reading, writing or manual operation under the lamp of the intelligent desk lamp. The scene acquisition module 150 can send the current application scenario to the control module 110, and the control module 110 adapts the current application scenario to the preset application scenario. If it meets the preset application scenario, the adjustment strategy corresponding to the preset application scenario can be called. Among them, the adjustment strategy can include parameters such as the distance between the lamp and the target area and the spacing between the lens module 130 and the light emitting module 120. The control module 110 outputs a first control signal according to the adjustment strategy, and the adjustment module 140 can adjust the distance between the lens module 130 and the light-emitting module 120 in the light-emitting area according to the first control signal to adjust the lighting range output by the light-emitting module 120 to the target area.

[0058] The smart lamp provided by the embodiment of the present invention sets the lens module 130 on the light output path of the light-emitting module 120, uses the scenario acquisition module 150 to obtain the user's current application scenario, and obtains the adjustment strategy of the lamp according to the current application scenario. The control module 110 controls the adjustment module 140 according to the adjustment strategy to adjust the distance between the lens module 130 and the light-emitting module 120, so that the lighting range output by the light-emitting module 120 to the target area can be automatically adjusted under different application scenarios to meet a variety of usage scenarios.

[0059] Based on the above embodiments, Figure 6 A schematic diagram of the structure of the light-emitting area of ​​a smart lamp is provided in an embodiment of the present invention. Figure 6 , the light-emitting area 121 includes a plurality of light-emitting sub-areas 1211 ; each light-emitting sub-area 1211 includes at least one light-emitting module 120 ;

[0060] The adjustment module 140 is provided with a plurality of adjustment sub-areas corresponding to the light-emitting sub-areas 1211; each adjustment sub-area includes at least one lens module 130;

[0061] The first control signal includes a plurality of first control sub-signals;

[0062] The adjustment module 140 is used to adjust the distance between the lens module 130 and the light emitting module 120 in the adjustment sub-area according to the corresponding first control sub-signal to adjust the illumination range outputted to the target area by the light emitting module 120 in the light emitting sub-area 1211 .

[0063] Specifically, as shown in the figure, the light-emitting modules 120 are arranged in a 4*4 array to form a light-emitting area. According to the control requirements of the light-emitting position, multiple light-emitting sub-areas 1211 can be defined in the light-emitting area 121. In the embodiment of the present invention, each light-emitting sub-area 1211 includes 2*2 light-emitting modules 120, and light-emitting sub-areas 1211, 2, 3 and 4 can be defined in the light-emitting area 121. Corresponding to the light-emitting sub-areas 1211, the adjustment module 140 also defines the adjustment sub-areas, and the lens module 130 in the adjustment sub-area corresponds to the light-emitting module 120 in the light-emitting sub-area 1211. By separately controlling the spacing between the lens module 130 and the light-emitting module 120 in the adjustment sub-area, the illumination range of the light-emitting sub-area 1211 in the light-emitting area 121 can be adjusted. Among them, according to the number of adjustment sub-areas, multiple first control sub-signals can be allocated, and each first control sub-signal is connected to the adjustment sub-area. For example, in some application scenarios, it is necessary to adjust the lighting range of light-emitting sub-areas 1, 2, 3 and 4 1211 according to the adjustment strategy, wherein the lighting range of light-emitting sub-areas 1211 2, 3 and 4 is the same, and the lighting range of light-emitting sub-area 1211 is larger than the lighting range of other positions. Then, the control module 110 can output four groups of first control sub-signals, and each group of first control sub-signals is sent to the adjustment sub-areas corresponding to light-emitting sub-areas 1, 2, 3 and 4. The adjustment sub-areas corresponding to light-emitting sub-areas 1, 2, 3 and 4 adjust the distance between the lens module 130 and the light-emitting module 120 in the adjustment sub-areas according to their respective first control sub-signals, thereby realizing the adjustment of the lighting range at different positions in the same light-emitting area 121.

[0064] Optionally, the control module 110 is connected to the light emitting module 120; the control module 110 is further configured to output a second control signal to the light emitting module 120 according to the adjustment strategy, and the light emitting module 120 adjusts the light emission parameters according to the second control signal.

[0065] Specifically, the adjustment strategy may also include light emission parameters such as color temperature and light intensity of the light emitting module 120. In other words, the control module 110 may output a second control signal according to the adjustment strategy, thereby controlling the light emitting module 120 to adjust light emission parameters such as color temperature and light intensity, thereby adjusting the lighting range and light emission parameters of the smart lamp, and further enriching the application scenarios.

[0066] Optional, combined Figure 6, the second control signal includes multiple second control sub-signals; the light-emitting module 120 in the light-emitting sub-area 1211 is used to adjust the light emission parameters of the light-emitting module 120 in the light-emitting sub-area 1211 according to the corresponding second control sub-signal.

[0067] Specifically, according to the number of light-emitting sub-areas 1211, multiple second control sub-signals can be allocated, and each second control sub-signal corresponds to the light-emitting module 120 of the light-emitting sub-area 1211. For example, in some application scenarios, the light emission parameters of light-emitting sub-areas 1211 No. 1, 2, 3 and 4 need to be adjusted according to the adjustment strategy, the light intensity of the light-emitting modules 120 of light-emitting sub-areas 1211 No. 2, 3 and 4 is the same, and the light intensity of the light-emitting module 120 of light-emitting sub-areas 1211 No. 1 is relatively low, then the control module 110 can output four groups of second control sub-signals, each group of second control sub-signals is sent to the light-emitting modules 120 of light-emitting sub-areas 1211 No. 1, 2, 3 and 4, and the light-emitting modules 120 of light-emitting sub-areas 1211 No. 1, 2, 3 and 4 adjust the light emission parameters according to their respective second control sub-signals. Therefore, the brightness of the light-emitting area 121 of the lamp can be adjusted according to the user's application scenario, so as to achieve the effect of saving power and avoiding light pollution.

[0068] Based on the above embodiments, Figure 7 A cross-sectional structural diagram of an adjustment module of an intelligent lamp is provided in an embodiment of the present invention. Figure 7 , the adjustment module 140 includes a plurality of adjustment units;

[0069] Each adjustment unit corresponds to each group of light emitting modules 120 one by one, and is arranged on the axis of the same side of the light emitting path of the light emitting module 120;

[0070] The adjustment unit includes a lens barrel 210, a support barrel 220, a current coil 230 and a magnetic unit 240;

[0071] The lens module 130 is fixedly disposed in the lens barrel 210, and the lens barrel 210 is sleeved in the support barrel 220, wherein a first opening is disposed on a side of the support barrel 220 away from the light emitting module 120, and the lens barrel 210 can move relatively in the first opening under the action of an external force; a side wall of the lens barrel 210 has a limiting protrusion for limiting the relative movement distance of the lens barrel 210;

[0072] The current coil 230 is arranged on the side wall of the lens barrel 210 on the side of the limiting protrusion close to the light-emitting module 120; the magnetic unit 240 is arranged on the side of the current coil 230 close to the light-emitting module 120; the current coil 230 is used to generate a magnetic field signal according to the first control signal, and cooperate with the magnetic unit 240 to provide power for relative movement of the lens barrel 210, so that the lens barrel 210 moves a preset distance to adjust the distance between the lens module 130 and the light-emitting module 120.

[0073] Specifically, the adjustment units are arranged in the same manner as the light emitting modules 120, each adjustment unit corresponds to a group of light emitting modules 120, and the adjustment unit is located on one side of the light emitting path of the light emitting module 120. Figure 7 The adjusting unit includes a lens barrel 210, a support barrel 220, a current coil 230 and a magnetic unit 240. The lens barrel 210 is used to carry the lens module 130. The lens module 130 is installed on a side of the lens barrel 210 away from the light emitting module 120. The lens module 130 can move with the lens barrel 210. The lens barrel 210 is located in the support barrel 220. At least part of the lens barrel 210 can move relatively in the first opening of the support barrel 220 under the action of an external force. Since the light emitting module 120 is in a fixed position, the distance between the lens module 130 and the light emitting module 120 can be adjusted when the lens barrel 210 is moved. In order to prevent the lens barrel 210 from moving away from the light emitting module 120, a limiting protrusion can be set on the side wall of the lens barrel 210. Exemplarily, in order to prevent the lens barrel 210 from moving away from the direction close to the light emitting module 120, the length of the lens barrel 210 can be greater than the length of the support tube 220, so when the lens barrel 210 moves close to the light emitting module 120, the lens barrel 210 is limited by the length of the side wall. The first control signal can be directly a current signal, or the current signal is indirectly generated by the first control signal. When the current coil 230 passes the current, the current coil 230 generates a magnetic field signal, and the magnetic unit 240 can provide an external magnetic field, and the Lorentz force is generated under the interaction of the current and the external magnetic field. By adjusting the direction and intensity of the current flowing into the current coil 230, the direction of the Lorentz force can be adjusted, thereby adjusting the moving direction of the lens barrel 210, and adjusting the distance between the lens module 130 and the light emitting module 120. According to the use requirements, the lens module 130 can be moved away from the light emitting module 120 or close to the light emitting module 120 to adjust the light shape so that the illumination range is diffused or concentrated. Figure 8-Figure 11 A schematic diagram of simulated light patterns at different spacings is provided for an embodiment of the present invention. It can be seen from the figure that different lighting ranges can be obtained by adjusting the spacing between the lens module 130 and the light emitting module 120. When an adjustment sub-area is provided, the adjustment units in the adjustment sub-area can be connected to the same group of first control sub-signals, so that the adjustment units in the adjustment sub-area can be controlled simultaneously.

[0074] Continue to see Figure 7 , Optionally, the regulating unit further includes a Hall sensor unit 250;

[0075] The Hall sensor unit 250 is disposed on the inner wall of the support tube 220 on one side of the current coil 230; the Hall sensor unit 250 is connected to the control module 110, and the Hall sensor unit 250 is used to detect the magnetic field signal and feed the magnetic field signal back to the control module 110;

[0076] The control module 110 is further configured to determine the distance between the lens module 130 and the light emitting module 120 according to the fed-back magnetic field signal.

[0077] Specifically, when the lens barrel 210 moves, the distribution of the magnetic field signal generated by the current coil 230 will also change, so that the magnitude and direction of the potential difference detected by the Hall sensor unit 250 will change. The Hall sensor unit 250 can feed back the change of the detected magnetic field signal to the control module 110, and the control module 110 can obtain the position of the lens barrel 210 through mathematical processing according to the change of the magnetic field signal. If the distance between the lens module 130 and the light emitting module 120 obtained according to the position of the lens barrel 210 is not moved to the right position or moves out of position, the control module 110 can send a corresponding compensation signal to fine-tune the adjustment module 140 again.

[0078] In the above embodiment, the scenario acquisition module 150 may include an image acquisition unit, and the control module 110 includes an artificial intelligence processing unit; the image acquisition unit is used to acquire the status characteristics of the user in the target area; the artificial intelligence processing unit has a preset application scenario, and the artificial intelligence processing unit is connected to the image acquisition unit. The artificial intelligence processing unit is used to match according to the status characteristics and the preset application scenario to obtain the current application scenario, and call the corresponding adjustment strategy according to the current application scenario.

[0079] Specifically, the image acquisition unit may be a camera unit or a camera unit, and the image acquisition unit may obtain the current action characteristics of the user by using image acquisition technology, wherein the action characteristics may include the user's gestures, wherein the gestures may include dynamic gestures or static gestures. For example, sliding up, sliding down, and pointing in a certain direction, etc., the action characteristics may also include the user's actions, such as raising the head, lowering the head, turning the head, and raising the hand. The artificial intelligence processing unit may infer the user's current application scenario by image processing and artificial intelligence processing, wherein the current application scenario may be adjusting the lighting range or light output parameters by using gestures. The current application scenario may also be a specific application scenario, such as reading, writing, or manual operation under the lamp of a smart desk lamp. The scenario acquisition module 150 may adapt the current application scenario to the preset application scenario, and if it meets the characteristics of the preset application scenario, the adjustment strategy corresponding to the preset application scenario may be retrieved. Among them, the adjustment strategy may include the distance between the lamp and the target area, the spacing between the lens module 130 and the light module 120, and the color temperature and light intensity of the light module 120. The control module 110 outputs a first control signal according to the adjustment strategy, and the adjustment module 140 can adjust the distance between the lens module 130 and the light-emitting module 120 in the light-emitting area 121 according to the first control signal to adjust the lighting range output by the light-emitting module 120 to the target area.

[0080] Fig.12This is a flow chart of a control method of a smart lamp provided by an embodiment of the present invention. This embodiment can be applied to the control of the lighting range of a smart lamp. The method can be executed by a smart lamp, and the device can be implemented in hardware and / or software. The method specifically includes the following steps:

[0082] Specifically, the scenario acquisition module 150 can be configured with a corresponding image acquisition unit, and the user's current action characteristics can be obtained by using image acquisition technology. By combining image processing and artificial intelligence control, the user's current application scenario can be inferred, such as reading, writing, or manual operation under the light of the smart desk lamp. The scenario acquisition module 150 can output the current application scenario to the control module.

[0083] S120, the control module selects an adjustment strategy for the lamp according to the current application scenario, and outputs a first control signal according to the adjustment strategy;

[0084] Specifically, the control module adapts the output to the preset application scenario, and if it meets the preset application scenario, the adjustment strategy corresponding to the preset application scenario can be called. The adjustment strategy may include parameters such as the distance between the lamp and the target area and the spacing between the lens module 130 and the light emitting module 120, and then the first control signal is output according to the adjustment strategy.

[0085] S130, the adjustment module adjusts the distance between the lens module and the light-emitting module in the light-emitting area according to the first control signal to adjust the lighting range output by the light-emitting module to the target area.

[0086] Specifically, the adjustment module 140 is arranged on the same side of the light-emitting path of the light-emitting module 120, and the lens module 130 is arranged on the adjustment module 140, and corresponds to the axis of the light-emitting path of each group of the light-emitting modules 120, that is, the light-emitting path of the light-emitting module 120 passes through the lens module 130, and the lens module 130 changes the light transmission path, which can be used to diverge light and focus light. It can be known that the height of the lamp irradiating to the target area, adjusting the distance between the lens module 130 and the light-emitting module 120, can change the illumination range of the light irradiating to the target area.

[0087] The control method of the smart lamp provided in the embodiment of the present invention obtains the user's current application scenario through the scenario acquisition module 150, and obtains the adjustment strategy of the lamp according to the current application scenario. The control module 110 controls the adjustment module 140 according to the adjustment strategy to adjust the distance between the lens module 130 and the light-emitting module 120, so that the lighting range output by the light-emitting module 120 to the target area can be automatically adjusted under different application scenarios to meet a variety of usage scenarios.

[0092] Specific, combined Figure 6, the light-emitting modules 120 are arranged in a 4*4 array to form a light-emitting area 121 as an example for explanation. According to the control requirements of the light-emitting position, a plurality of light-emitting sub-areas 1211 can be delineated in the light-emitting area 121.

Corresponding to the light-emitting sub-areas 1211, the adjustment sub-areas are also delineated on the adjustment module 140, and the lens module 130 in the adjustment sub-area corresponds to the light-emitting module 120 in the light-emitting sub-area 1211. By separately controlling the distance between the lens module 130 and the light-emitting module 120 in the adjustment sub-area, the illumination range of the light-emitting sub-area 1211 in the light-emitting area 121 can be adjusted. Among them, according to the number of adjustment sub-areas set, a plurality of first control sub-signals can be allocated, and each first control sub-signal is connected to the adjustment sub-area. For example, in some application scenarios, it is necessary to adjust the lighting range of light-emitting sub-areas 1, 2, 3 and 4 1211 according to the adjustment strategy, wherein the lighting range of light-emitting sub-areas 1211 2, 3 and 4 is the same, and the lighting range of light-emitting sub-area 1211 is larger than the lighting range of other positions. Then, the control module 110 can output four groups of first control sub-signals, and each group of first control sub-signals is sent to the adjustment sub-areas corresponding to light-emitting sub-areas 1, 2, 3 and 4. The adjustment sub-areas corresponding to light-emitting sub-areas 1, 2, 3 and 4 adjust the distance between the lens module 130 and the light-emitting module 120 in the adjustment sub-areas according to their respective first control sub-signals, thereby realizing the adjustment of the lighting range at different positions in the same light-emitting area 121.

For example, sliding up, sliding down, and pointing in a certain direction, etc., the action characteristics may also include the user's actions, such as raising the head, lowering the head, turning the head, and raising the hand. The artificial intelligence processing unit may infer the user's current application scenario by image processing and artificial intelligence processing, wherein the current application scenario may be adjusting the lighting range or light output parameters by using gestures.
