[0030] Figure 2 This is a flowchart illustrating the LED strip light emission control method of the present invention.

[0031] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0032] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0033] like Figure 1 As shown, Figure 1 This is a schematic diagram of the terminal structure of the hardware operating environment involved in the embodiments of the present invention.

[0034] like Figure 1 As shown, the terminal may include: a processor 1001, such as a CPU; a communication bus 1002; a user interface 1003; a network interface 1004; and a memory 1005. The communication bus 1002 is used to enable communication between these components.

The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0035] Optionally, the terminal may also include a camera, RF (Radio Frequency) circuitry, sensors, audio circuitry, a WiFi module, and so on. Sensors may include light sensors, motion sensors, and other sensors. Specifically, light sensors may include ambient light sensors and proximity sensors. The ambient light sensor can adjust the display brightness according to the ambient light level, while the proximity sensor can turn off the display and / or backlight when the mobile terminal is moved to the ear. As a type of motion sensor, a gravity accelerometer can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity, and can be used for applications that identify the mobile terminal's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition functions (such as pedometers, taps), etc. Of course, the mobile terminal may also be equipped with other sensors such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, which will not be elaborated here.

[0036] Those skilled in the art will understand that Figure 1 The terminal structure shown does not constitute a limitation on the terminal and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0037] like Figure 1As shown, the memory 1005, which serves as a computer storage medium, may include an operating system, a network communication module, a user interface module, and a data calculation program.

[0038] exist Figure 1 In the terminal shown, network interface 1004 is mainly used to connect to the backend server and communicate with it; user interface 1003 is mainly used to connect to the client (user terminal) and communicate with it; while processor 1001 can be used to call the data calculation program stored in memory 1005 and perform the following operations:

[0039] Ambient light intensity is monitored in real time using an ambient light sensor;

[0040] When a human activity signal is detected, the brightness of the light strip is automatically adjusted according to the ambient light intensity to bring the light strip to a preset illuminance level.

[0041] Furthermore, the processor 1001 can call the data calculation program stored in the memory 1005 and also perform the following operations:

[0042] The system detects human movement trajectories using motion sensors and generates the direction of human movement.

[0043] The light strip's luminous area and brightness are dynamically adjusted according to the direction of human movement.

[0044] Furthermore, the processor 1001 can call the data calculation program stored in the memory 1005 and also perform the following operations:

[0045] The light strip is divided into multiple independent control sections.

[0046] Furthermore, the processor 1001 can call the data calculation program stored in the memory 1005 and also perform the following operations:

[0047] The control sections of the light strip are illuminated sequentially according to the direction of human movement;

[0048] The brightness of the controlled sections is controlled by the multi-interval segmented light emission control model.

[0049] The specific embodiments of the data storage device used in this invention are basically the same as the embodiments of the data storage method described below, and will not be repeated here.

[0050] Reference Figure 2 The first embodiment of the present invention provides a method for controlling the light emission of a light strip, the method comprising:

[0051] Step S10: Monitor ambient light intensity in real time using an ambient light sensor;

[0052] Step S20: When a human activity signal is detected, the brightness of the light strip is automatically adjusted according to the ambient light intensity to bring the light strip to a preset illuminance level.

[0053] In this embodiment, the brightness of the light strip can be adjusted according to the intensity of ambient light, and the state of the light strip can also be adjusted according to human activity signals, thus improving the practicality of the light strip.

[0054] In the initial stage of use, a light strip light control model can be established based on the acquired ambient light intensity. Specifically, the light strip light control model is a multi-interval segmented light emission control model, which is as follows:

[0055]

[0056] Where E is the ambient light intensity and L(E) is the target brightness of the light strip.

[0057] The target brightness of the light strip is in the low-light zone when the ambient light intensity E≤50lux, satisfying the following:

[0058] L(E) = K1E 3 +K2E 2 +K3E;

[0059] Among them, 0.001≤K1≤0.005, -0.05≤K2≤-0.01, 0.3≤K3≤0.7, the cubic gain coefficient K1 can enhance the sensitivity in the dark area: even a slight change in light can cause a significant brightness response, the quadratic damping coefficient K2 can suppress overshoot in the low light area: to prevent excessive brightness in extremely weak light, and the linear adjustment coefficient K3 is the basic brightness adjustment slope.

[0060] The target brightness of the light strip falls into the medium light zone when the ambient light intensity is lux ≤ E ≤ 200 lux, satisfying the following conditions:

[0061] L(E) = K4E 2 +K5E+K6;

[0062] Among them, 0.0003≤K4≤0.0008, 0.08≤K5≤0.12, 4≤K6≤6, the curvature control coefficient K4 is used to smooth the brightness transition and counteract the mechanical feeling of linear growth, the slope coefficient K5 is mainly used to adjust the amplitude (the brightness adjustment rate caused by each lux change), and the brightness base coefficient K6 ensures minimum visibility: even when the ambient light is sufficient, it still maintains 5% base backlight.

[0063] The target brightness of the light strip falls into the high-brightness zone when the ambient light intensity E > 200 lux, satisfying the following:

[0064]

[0065] Among them, 0.5≤K7≤0.8, 10≤K8≤20, the compression gain coefficient K7 is used to control the response speed and slow down the brightness increase under strong light, while the brightness lower limit coefficient K8 prevents the light strip from being completely turned off when the ambient light is extremely strong, maintaining 15% basic lighting.

[0066] In addition, the step of automatically adjusting the brightness of the light strip according to the ambient light intensity when a human activity signal is detected includes:

[0067] The system detects human movement trajectories using motion sensors and generates the direction of human movement.

[0068] The light strip's luminous area and brightness are dynamically adjusted according to the direction of human movement.

[0069] The light strip is divided into multiple independent control sections, each of which can be turned on and off independently. Therefore, the control sections of the light strip can be lit sequentially according to the direction of human movement. The brightness of each control section is controlled by the multi-section segmented light emission control model.

[0070] When a user walks from the bedroom to the bathroom at night, the right light strip lights up sequentially according to the direction of movement, and the brightness automatically increases to 80% of the maximum brightness as the ambient light decreases.

[0071] When the light is first turned on, it is suitable for low-light areas. As more light strips are activated, it will gradually be used in medium-light and high-light areas, thereby achieving a gradual increase in brightness. This allows users to adapt to the environment more easily as they move around.

[0072] Furthermore, embodiments of the present invention also propose a light strip controller, the light strip controller comprising:

[0073] The acquisition module is used to monitor ambient light intensity in real time via an ambient light sensor;

[0074] The acquisition module is used to automatically adjust the brightness of the light strip according to the ambient light intensity, so that the light strip is at a preset illuminance level.

[0075] It should be noted that those skilled in the art will understand that, for the sake of convenience and brevity, the specific working processes of the above-described apparatus and modules can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

[0076] Furthermore, embodiments of the present invention also propose a light strip, the light strip comprising:

[0077] Power adapter;

[0078] Multiple light-emitting units, each light-emitting unit including a driver chip and at least one LED bead, wherein the driver chip is used to drive at least one of the LED beads;

[0079] The controller executes the above-described LED strip illumination control method.

[0080] The controller includes a computer-readable storage medium storing a light strip illumination control program. When executed by a processor, the light strip illumination control program implements the method described above. Specific embodiments of the computer-readable storage medium of this invention are essentially the same as the embodiments of the light strip illumination control method described above, and will not be repeated here.
