[0026] As a preferred embodiment, as Figure 3As shown, 14 LED lamp beads are arranged on the lamp panel 1 at intervals, including lamp bead R0 in the central area 3, lamp bead R1, lamp bead R2, lamp bead R3, lamp bead R4 in the first peripheral area 41, lamp bead R5, lamp bead R6, lamp bead R7, lamp bead R8 in the second peripheral area 42, and lamp bead R9, lamp bead R10, lamp bead R11, lamp bead R12, lamp bead R13 in the third peripheral area 43, wherein the lamp bead R1, the lamp bead R2, the lamp bead R3, and the lamp bead R4 are arranged around the periphery of the lamp bead R0, and the lamp bead R1 and the lamp bead R2 are located on the left side of the lamp bead R0, the lamp bead R3 and the lamp bead R4 are located on the right side of the lamp bead R0, the lamp bead R5 and the lamp bead R6 are located on the left side of the lamp bead R1 and the lamp bead R2, the lamp bead R7 and the lamp bead R8 are located on the right side of the lamp bead R3 and the lamp bead R4, the lamp bead R9, the lamp bead R10, and the lamp bead R11 are located on the left side of the lamp bead R5 and the lamp bead R6, and the lamp bead R12 and the lamp bead R13 are located on the right side of the lamp bead R7 and the lamp bead R8.

[0027] Preferably, a touch sensor is further arranged on the central area 3, as a preferred embodiment, the touch sensor corresponds to the position of the lamp bead R0 in the central area 3, the control module is electrically connected with the touch sensor, for receiving the touch trigger signal of the user, the touch sensor is preferably a capacitive touch sensor, which is attached or integrated on the lamp panel 1 and located in the central area 3, so that the user can directly touch the light-emitting area to realize interaction, the touch sensor detects the capacitance change of its surface in real time, and when a touch event meeting a preset threshold is detected, a trigger signal is sent to the control module, thereby realizing the touch interaction mode, the touch interaction mode includes a first unlocking mode, which focuses on intuitively feeding back the touch state of the user through significant changes in light brightness, and is suitable for scenes that need to clearly indicate the success of triggering.

[0028] Preferably, the first unlocking mode includes a normal stage and a touch stage. In the normal stage, the control module controls the plurality of light-emitting units 2 of the peripheral area 4 to be always on at a first brightness value, and the light-emitting units 2 of the central area 3 to be always on at a second brightness value lower than the first brightness value, that is, when the user does not touch, the control module controls the light-emitting units 2 of the first peripheral area 41, the second peripheral area 42, and the third peripheral area 43 to be always on at a first brightness value L1 (for example, a 3W lamp bead has a highest luminous value of about 420lm, and the first brightness value L1 is 70% of the highest luminous value, that is, 294lm), as basic lighting or position indication, while controlling the light-emitting units 2 of the central area 3 to be always on at a second brightness value L2 (for example, a 3W lamp bead has a highest luminous value of about 420lm, and the second brightness value L2 is 30% of the highest luminous value, that is, 126lm) which is significantly lower than L1, this brightness difference makes the central area 3 form a "focus" or "button" prompt in vision, guiding the user to touch.

[0029] In the touch phase, the control module controls all light emitting units 2 to switch to a third luminance value constant higher than the first luminance value in response to the trigger signal of the touch sensor, that is, when the control module determines that the user has touched in response to the trigger signal of the touch sensor, the control module immediately enters the touch phase and controls the luminance of all light emitting units 2 (the center area 3, the first peripheral area 41, the second peripheral area 42, and the third peripheral area 43) to switch to a third luminance value L3 higher than the first luminance value L1 (for example, the highest luminous flux value of a 3W lamp bead is about 420 lm, and the third luminance value L3 is 100% of the highest luminous flux value, that is, 420 lm), and the system remains constant. This operation produces strong visual feedback, clearly informing the user that "touch has been recognized".

[0030] Preferably, the first unlocking mode further includes a touch completion phase. In the touch completion phase, the control module controls all light emitting units 2 to be turned off in response to the interruption of the trigger signal of the touch sensor, and automatically switches to the normal phase after a fifth predetermined time period, that is, when the user's finger leaves and the trigger signal of the touch sensor is interrupted, the control module immediately controls all light emitting units 2 to be turned off, and the system enters a short dark state for a fifth predetermined time period T5 (T5 is preferably 2 seconds). After the T5 time period ends, the control module automatically switches the system light state back to the normal phase, that is, the first peripheral area 41, the second peripheral area 42, and the third peripheral area 43 are constant at the first luminance value L1, and the center area 3 is constant at the second luminance value L2, preparing for the next interaction.

[0031] As a preferred embodiment, when the user does not touch, the control module controls the lamp beads R1, R2, R3, R4 located in the first peripheral area 41, the lamp beads R5, R6, R7, R8 located in the second peripheral area 42, and the lamp beads R9, R10, R11, R12, R13 located in the third peripheral area 43 to be always on at a first brightness value L1, and the lamp bead R0 of the center area 3 is always on at a second brightness value L2 which is obviously lower than L1. When the control module determines that the user has touched in response to the trigger signal of the touch sensor, it immediately enters the touch stage, and the control module controls the brightness of the lamp beads R0, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 to be switched to a third brightness value L3 which is higher than the first brightness value L1 and keep on. When the user's finger leaves and the trigger signal of the touch sensor is interrupted, the control module immediately controls the lamp beads R0, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 to be turned off, and the system enters a short dark state for a fifth preset time T5. After the T5 time ends, the control module automatically controls the lamp beads R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 to be always on at the first brightness value L1, and the lamp bead R0 to be always on at the second brightness value L2, preparing for the next interaction.

[0032] In addition, the embodiment also provides a starry night lamp effect external pull handle lighting method, applied to the starry night lamp effect external pull handle system, as shown in the figure, comprising the following steps: Figure 4 Obtaining a trigger signal of a touch sensor; the control module continuously monitors the state of the touch sensor electrically connected thereto. When the user touches the touch sensor integrated on the center area 3, the sensor detects the change in capacitance and generates a trigger signal, which is sent to the control module in real time; In response to the trigger signal, control a plurality of light emitting units 2 to execute a preset unlocking light effect; the control module obtains the trigger signal and enters a preset touch interaction mode in response to the trigger signal.

[0033] ​Preferably, when the trigger signal is not received, the light-emitting unit 2 in the outer area 4 is controlled to be constantly lit at a first brightness value, while the light-emitting unit 2 in the central area 3 is controlled to be constantly lit at a second brightness value lower than the first brightness value; the control module controls all light-emitting units 2 in the first outer area 41, the second outer area 42, and the third outer area 43 to be constantly lit at the first brightness value L1 as background lighting, while the light-emitting unit 2 in the central area 3 is controlled to be constantly lit at a second brightness value L2 that is significantly lower than L1, forming a visual focus and indicating a touchable area.

[0034] During the period when the trigger signal is received (i.e., when the user's finger is continuously touching), all light-emitting units 2 are controlled to switch to the third brightness value and remain constantly lit. That is, the control module immediately issues a new driving command to control the brightness of all light-emitting units 2 to instantly switch to a higher third brightness value L3 and remain constantly lit. This significant brightness jump clearly conveys to the user the immediate feedback that "the touch is effective and the system has been activated".

[0035] When the trigger signal disappears (i.e., the user's finger leaves), all light-emitting units 2 are turned off. After a fifth preset time, the system returns to a state where the outer area 4 is constantly lit at the first brightness value and the central area 3 is constantly lit at the second brightness value. That is, the control module then controls all light-emitting units 2 to turn off simultaneously, and the system enters a brief, continuous dark state for a fifth preset time T5. After the T5 time ends, the control module automatically restores the system to the light state of the normal standby step, completing a complete interactive cycle and waiting for the next trigger.

[0036] Example 2 An external pull handle system with starry sky light effect. The difference between this embodiment and the first specific embodiment is that the touch interaction mode includes a second unlocking mode, which uses a complete dynamic light sequence as feedback, making it more interesting and ritualistic.

[0037] Preferably, the second unlocking mode includes a touch phase; During the touch phase, the control module responds to the touch sensor being triggered by performing the ripple mode a preset number of times, and then remains off after completion. That is, when the control module responds to the touch sensor being triggered, it immediately starts the preset dynamic effect. First, the control module executes the complete ripple mode a preset number of times N1 (N1 is preferably 1 time). Specifically, it starts lighting up from the central area 3, and then lights up the first peripheral area 41, the second peripheral area 42, and the third peripheral area 43 in sequence. Each area is lit for a duration of T3 (T3 is preferably 1 second) and then turns off, forming a light wave that spreads outward. After completing the N1 ripple effect, all light-emitting units 2 remain off.

[0038] Preferably, the second unlocking mode further includes a touch completion phase; In the touch completion stage, after the center area 3 and each of the peripheral areas 4 are turned off, the control module controls all the light emitting units 2 to perform the preset number of breathing modes, that is, the control module controls all the light emitting units 2 to synchronously perform the preset number N2 (N2 is preferably 3) of breathing modes, each breathing mode interval is 2 seconds, all the light emitting units 2 synchronously perform N2 times of breathing cycles from dark to light and then to dark, the dynamic sequence (ripple + breathing) jointly constitutes a complete unlocking feedback, after all the effects are played, the system can be kept off or switched to other modes according to the preset, such as the ripple mode, the constant light mode, or the breathing mode is continuously kept.

[0039] As a preferred embodiment, when the control module responds to the touch sensor being triggered, the preset dynamic effect is immediately started, first, the control module performs the preset number N1 of complete ripple modes, the lamp beads R0 at the center area 3 are first lighted, then the lamp beads R1, R2, R3, R4 located at the first peripheral area 41, the lamp beads R5, R6, R7, R8 located at the second peripheral area 42, and the lamp beads R9, R10, R11, R12, R13 located at the third peripheral area 43 are sequentially lighted, each area is lighted for T3 time length and then turned off, forming a light wave diffusing outward, after N1 times of ripple effects are completed, all the light emitting units 2 are kept off, the control module controls the lamp beads R0, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 to synchronously perform the preset number N2 of breathing modes, each breathing mode interval is 2 seconds, the lamp beads R0, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 synchronously perform N2 times of breathing cycles from dark to light and then to dark, after all the effects are played, the system can be kept off or switched to other modes according to the preset, such as the ripple mode, the constant light mode, or the breathing mode is continuously kept.

[0040] In addition, the embodiment also provides a starry night lamp effect outer pull handle lighting method, which is applied to the starry night lamp effect outer pull handle system and comprises the following steps: Figure 5 As shown in the drawing, the steps are as follows: A trigger signal of a touch sensor is acquired; a control module continuously monitors a state of a touch sensor electrically connected thereto, when a user touches the touch sensor integrated on the center area 3, the sensor detects a capacitance change and generates a trigger signal, the signal is sent to the control module in real time; In response to the trigger signal, the control module controls the plurality of light emitting units 2 to execute a preset unlocking light effect; once the control module acquires the trigger signal, the control module enters a preset touch interaction mode in response to the trigger signal.

[0041] Preferably, when the trigger signal is acquired (usually triggered by a touch instantaneously without needing to be pressed continuously), the corresponding regions are sequentially lighted up in order from the central region 3 to the peripheral regions 4, and each region is extinguished after a third preset time length after being lighted up, that is, the control module immediately starts a preset light animation sequence. First, a preset number N1 of ripple patterns are executed, and the control module sequentially and rapidly light up all the light emitting units 2 of the corresponding regions in a preset order from the central region 3 to the first peripheral region 41, the second peripheral region 42, and the third peripheral region 43. Each region is extinguished after a third preset time length T3, simulating the effect of light waves spreading from the center to the periphery.

[0042] After all the regions are sequentially lighted up and extinguished, that is, the ripple effect is played, the control module controls all the light emitting units 2 to synchronously change in a preset number of cycles of a first preset time length in which the brightness is raised from a minimum value to a maximum value and a second preset time length in which the brightness is lowered from the maximum value to the minimum value until the unlocking action is completed. The system can be kept extinguished, or switched to other modes such as a breathing mode, a constant light mode, or continuously kept in the ripple mode according to a preset.

[0043] As a preferred embodiment, when the trigger signal is not acquired, the control module controls the light emitting units 2 of the peripheral regions 4 to be constantly lighted up at a first brightness value, and the light emitting units 2 of the central region 3 to be constantly lighted up at a second brightness value lower than the first brightness value; or the control module controls all the light emitting units 2 to be lighted up at the same brightness value; or the control module extinguishes all the light emitting units 2 of the peripheral regions 4 and light up the light emitting units 2 of the central region 3 at an arbitrary brightness value.
