[Technical Field]

[0001] FIELD OF THE INVENTION This application relates to the field of lighting fixtures, and more particularly to rotatable sleep lamps. [Background technology]

[0002] Currently, most commonly available sleep lamp products on the market mainly use fixed brightness adjustment or simple timing start-up / shutdown functions. These products usually use buttons or touch controls to turn the light on and off. In addition, in terms of brightness adjustment, most of the prior art uses step-by-step brightness adjustment, which pre-sets multiple fixed brightness levels for users to choose from, and is unable to achieve gradual changes in brightness at specific times according to user needs. As a result, the brightness adjustment of the rotatable sleep lamps in the prior art is not continuous, has a single function, and is inconvenient to operate.

[0003] Therefore, the prior art still needs improvement and development. Summary of the Invention [Problem to be solved by the invention]

[0029] In one possible embodiment of the present application, the lighting assembly 200 is disposed inside the lampshade 100 and connected to the support assembly 400, as shown in FIG.

[0030] Furthermore, the lighting assembly 200 is a lighting module, and as shown in FIG. 4, the lighting module has a plate-like structure, and the bottom of the lighting module is connected to the support frame 402 of the support assembly 400 .

[0031] 4, the lighting assembly 200 may be provided in multiple layers. The support assembly 400 penetrates the lighting assembly 200 to further fix the position of the lighting assembly 200.

[0033] Furthermore, the main body 300 is made of a solid, hard material, and the cylindrical structure of the main body 300 defines an accommodation space for accommodating and protecting the support assembly 400 and the control assembly 500. The main body 300 is provided with a button hole, the shape and position of which correspond to the shape and position of an adjustment key 520 provided in the accommodation space, and the adjustment key 520 extends through the button hole to the outside of the main body 300, thereby allowing a user to operate it from the outside and maintaining the sealing and protection of the internal space of the main body 300.

[0034] In one possible embodiment of the present application, as shown in FIG. 1, the support assembly 400 is provided in the main body 300 and is connected to the control assembly 500 and the lampshade 100 respectively, and the support assembly 400 can realize coaxial rotation of the lampshade 100 and the control assembly 500.

[0035] Furthermore, the support assembly 400 is detachably connected to the control assembly 500, and when the lampshade 100 rotates, it transmits the rotational motion to the control assembly 500, which further changes the current in the circuit, thereby realizing the brightness adjustment function.

[0036] 1 , the support assembly 400 includes a support wall 401, a connecting portion 403, and a support frame 402, where the support wall 401, the connecting portion 403, and the support frame 402 are integrally molded and connected in order, the support wall 401 has a gooseneck-shaped cross section, and the support frame 402 is a vertical frame. The support wall 401 is detachably connected to the lampshade 100, one end of the support frame 402 is connected to the lighting assembly 200, and the other end of the support frame 402 is vertically connected to the control assembly 500, which is supported above the main body 300 via the support assembly 400. The support wall 401 and the support frame 402 extend vertically downward to form the connecting portion 403, which is provided above the control assembly 500.

[0037] Furthermore, the support assembly 400 is manufactured using a one-piece molding process and includes three parts: the support wall 401, the support frame 402, and the connecting part 403. The support wall 401 adopts a gooseneck design and has bending characteristics. The support frame 402 is a vertical frame structure and provides rigid support. The connecting part 403 is connected to the support wall 401 and the support frame 402 as a transition part. The support wall 401 of the support assembly 400 is connected to the lampshade 100, the bottom of the support frame 402 is perpendicular to the control assembly 500, and the connecting part 403 extends vertically downward from the support wall 401 and the support frame 402 and is provided above the control assembly 500, so that the control assembly 500 is stably provided on the main body and the support assembly.

[0038] 5 and 11, in one possible embodiment of the present application, the control assembly 500 is provided inside the main body 300 and detachably connected to the support assembly 400, and the encoder 514 of the control assembly 500 can rotate with the rotation of the support assembly 400 to further adjust the brightness and mode of the rotatable sleep lamp. The control assembly 500 is provided with the adjustment key 520, which can pass through a button hole of the support assembly 400. The adjustment key 520 can further adjust the brightness, color temperature, and mode of the rotatable sleep lamp.

[0039] Furthermore, as shown in FIG. 6, the control assembly 500 is provided inside the rotatable sleep lamp and is coaxially connected to the lampshade 100 via the support assembly 400, and the encoder 514 of the control assembly 500 can rotate with the rotation of the lampshade 100, and further adjust the brightness and mode of the rotatable sleep lamp.

[0040] Specifically, as shown in Figures 7 and 9, the control assembly includes an adjustment part 510 and the adjustment key 520, and the adjustment part 510 includes, arranged from top to bottom, a first circuit board 511, a sleeve 517, an encoder 514, a connector 515, a second circuit board 512, a third circuit board 513 and a PIN 516.

[0041] 10 , the bottom of the encoder 514 is connected to the third circuit board 513, and the third circuit board 513 is electrically connected to the second circuit board 512. The first circuit board 511 is movably mounted above the second circuit board 512 via the sleeve 517. The encoder 514 is a rotary incremental encoder and is connected to the second circuit board 512 and the third circuit board 513 via the sleeve 517, respectively, with the central axis of the encoder 514 being parallel to the central axis of the sleeve 517. The connector 515 is used to realize the electrical connection between the second circuit board 512 and the first circuit board 511. The pin 516 is perpendicular to the third circuit board 513 and is used to connect the second circuit board 512 and the third circuit board 513.

[0042] Rotating the encoder 514 causes the encoder 514 to output a pulse signal, and the microcontroller dynamically adjusts the pulse width modulation based on the signal output from the encoder 514 to change the brightness and color temperature of the rotatable sleep lamp. The number of counted pulses determines the number of rotation steps, thereby obtaining information on the rotation angle and determining the rotation direction. When the encoder 514 rotates clockwise, the color temperature and brightness gradually increase, and when the encoder 514 rotates counterclockwise, the color temperature and brightness gradually decrease. In this application, the encoder 514 is used to achieve stepless adjustment of the brightness and color temperature of the rotatable sleep lamp.

[0043] Furthermore, the adjustment part 510 adopts a multi-layer circuit board structure design, and the third circuit board 513 is horizontally fixed to the main body 300. The second circuit board 512 and the third circuit board 513 are electrically connected by welding to form a stable circuit. The first circuit board 511 is movably installed above the second circuit board 512 via the sleeve 517, and when the power switch is pressed, the first circuit board 511 is electrically connected to the second circuit board 512 via the connector 515.

[0044] Specifically, as shown in FIG. 9 , the PIN 516 is a rigid metal conductor, one end of the PIN 516 is welded vertically to the third circuit board 513, and the other end of the PIN 516 extends to the second circuit board 512, thereby realizing an electrical connection between the third circuit board 513 and the second circuit board 512 and maintaining circuit continuity between the second circuit board 512 and the third circuit board 513.

[0045] Furthermore, the PINs 516 are attached perpendicularly to the surface of the third circuit board 513, so that the second circuit board 512 can be arranged parallel to and stacked above the third circuit board 513, and the PINs 516 provide a stable mechanical connection and an efficient electrical connection between them.

[0046] Specifically, as shown in Figures 8 and 9, the outer wall of the sleeve 517 has a limiting structure 5171, and the second circuit board 512 is supported by the limiting structure 5171, thereby ensuring that the second circuit board 512 is arranged parallel to the first circuit board 511, and the second circuit board 512 is movably connected to the sleeve 517 via the limiting structure 5171.

[0047] Furthermore, the first circuit board 511, the second circuit board 512, and the third circuit board 513 all adopt a concentric disk structure, and the first circuit board 511, the second circuit board 512, and the third circuit board 513 are stacked with the sleeve 517 as a common axis, and the second circuit board 512 and the third circuit board 513 are connected to the support structure as a basic fixing layer.

[0048] Furthermore, as shown in FIG. 10 , a plurality of limiting structures 5171 are provided on the outer wall of the sleeve 517, and the upper surfaces of the limiting structures 5171 are in contact with the bottom of the second circuit board 512. The second circuit board 512 is supported by the limiting structures 5171 and connected to the sleeve 517 via a gap, thereby ensuring that when the second circuit board 512 is stationary, the sleeve 517 can smoothly pass through the central hole of the second circuit board 512 and move up and down.

[0049] Specifically, as shown in FIG. 10 , the second circuit board 512 is provided with the connector 515, and when the power switch is pressed, the relative positions of the first circuit board 511 and the second circuit board 512 change, and the first circuit board 511 moves downward until the first circuit board 511 achieves circuit conduction with the second circuit board 512 through the connector 515.

[0050] Furthermore, a sensor element is provided at the bottom of the first circuit board 511. When the power switch is pressed, the sensor element on the first circuit board 511 connects to the connector 515, and the sleeve 517 moves downward, and the first circuit board moves downward along with the sleeve 517, until the circuit is turned on and the lighting function is realized.

[0051] Specifically, as shown in FIG. 8, the first circuit board 511 is fitted into the sleeve 517 through a central hole, thereby realizing a rigid connection with the sleeve 517 and allowing the first circuit board 511 to move in accordance with the movement of the sleeve 517.

[0052] Furthermore, the first circuit board 511 is fitted onto the outer periphery of the tip of the sleeve 517 through a central hole drilled in the center, and is firmly connected to the sleeve 517 by a fastener or a clamping fit. The encoder 514 is mounted vertically through a predetermined position of the third circuit board 513, and its pins are electrically connected to corresponding pins on the third circuit board 513. The displacement or angle change of the encoder 514 is converted into an electric signal, and the microcontroller on the third circuit board 513 receives the electric signal output from the encoder 514 in real time to further adjust the color temperature and brightness change.

[0053] Furthermore, the third circuit board 513 continuously and stably receives and processes the electrical signal output from the encoder 514 through internal wiring and a signal collection circuit, and then realizes corresponding functions, such as adjusting lighting parameters or switching working modes, based on the changes in the electrical signal.

[0054] In one possible embodiment of the present application, the encoder 514 rotates to generate two sets of orthogonal pulse signals, called Phase A and Phase B, with a phase difference of 90 degrees. Since the frequency of the pulse signals is directly proportional to the rotation speed of the encoder 514, the phase relationship of the pulses is used to determine the direction of rotation. The microcontroller determines whether the encoder is rotating clockwise or counterclockwise based on the order of the level changes of Phase A and Phase B. When rotating clockwise, the phase of the Phase A pulse is earlier than Phase B, while when rotating counterclockwise, the phase of the Phase A pulse is later than Phase B. When rotating clockwise, the microcontroller realizes this by pulse width modulation. When Phase A changes before Phase B, the microcontroller recognizes clockwise rotation and increases the brightness or color temperature control parameters accordingly.

[0055] 1, when the lampshade 100 is rotated, the support assembly 400 rotates together with the lampshade 100, and the support assembly 400 rotates the encoder 514 around its central axis, causing the encoder 514 to rotate together with the support assembly 400. When the encoder 514 rotates, it generates a pulse signal that changes with the direction and angle of rotation. The microcontroller receives this signal, calculates brightness adjustment parameters, and drives the light source module of the lighting assembly 200 by a method such as pulse width modulation, thereby achieving brightness and color temperature changes of the lighting assembly 200.

[0056] 11 , the control assembly 500 further includes mode keys 521 provided on the outer wall of the main body 300 and a timing key 522 provided at the bottom of the main body 300. The mode keys 521 include at least one independent button, and each mode key 521 corresponds to one status mode of the rotatable sleep lamp, and the mode keys 521 are assembled in button holes on the outer wall of the main body 300.

[0057] The mode key 521 is connected to a pin of the microcontroller. When the mode key 521 is pressed, a circuit is turned on, and the microcontroller detects the level change and turns on the corresponding indicator lamp, simultaneously activating a preset status mode. The microcontroller has a built-in timer. When the preset time arrives, the microcontroller outputs a pulse width modulation signal to drive the circuit to achieve gradational change adjustment of brightness and color temperature. The microcontroller dynamically adjusts the color temperature of the lighting assembly 200 based on the input signal of the color temperature adjustment button and the actual change of the built-in timer.

[0058] Furthermore, the control assembly 500 is provided with the adjustment key 520, which controls the on / off state and operation mode of the rotatable sleep lamp. For example, the rotatable sleep lamp includes three mode keys 521, corresponding to sleep mode, power switch, and wake-up mode, respectively. The mode keys 521 are assembled and fixed into button holes drilled on the outer wall of the main body 300, ensuring a flat appearance, a comfortable touch, and structural stability. The timing key 522 includes different timing duration ranges, such as, but not limited to, 5 hours, 6 hours, and 7 hours. The timing duration range can be selected by sliding the timing key 522.

[0059] Furthermore, the mode keys 521 are connected to corresponding general-purpose input / output pins of the microcontroller. When a user presses a mode key 521, the circuit where the mode key 521 is located is turned on, and the microcontroller detects the level change of the corresponding pin in real time, thereby driving the indicator lamp related to the mode to light up, providing visual feedback, and synchronously activating the corresponding status mode built into the device.

[0060] Furthermore, the microcontroller is equipped with a programmable timer module. In response to the input signal from the timing key, the microcontroller can dynamically adjust the control signal output to the lighting assembly 200 based on the actual setting change of the built-in timer. When the device runs to a preset time, the microcontroller automatically outputs a pulse width modulation signal to drive the circuit to smoothly modulate the power supply current and voltage of the lighting assembly 200, further realizing stepless gradation adjustment of the brightness and color temperature of the light to meet the lighting needs of users in different usage scenarios.

[0061] To summarize, as shown in FIG. 1 , the rotatable sleep lamp described in the present application can achieve stepless adjustment by rotating the lampshade 100 and then rotating the support assembly 400 to change the encoder 514. When the mode key corresponding to the power switch is pressed, the first circuit board 511 is electrically connected to the second circuit board 512, realizing circuit connection and further realizing the lighting function. When the lampshade 100 is rotated, force is transmitted to the support frame 402 of the support assembly 400, which then rotates the encoder 514. When the encoder 514 rotates, it generates a pulse signal that changes with the rotation direction and angle. The microcontroller receives the signal, calculates brightness adjustment parameters, and drives the light source module of the lighting assembly 200 by a method such as pulse width modulation, thereby realizing the brightness change of the lighting assembly 200.

[0062] Specifically, the encoder 514 is the encoder EC11. When the lampshade 100 rotates, the support assembly 400 rotates with the lampshade 100, thereby rotating the encoder 514. When the knob of the encoder EC11 is rotated clockwise, the phase of the A-phase pulse is earlier than the B-phase pulse, whereas when the knob is rotated counterclockwise, the phase of the A-phase pulse is later than the B-phase pulse. The direction of rotation of the encoder can be determined by detecting the rising and falling edges of the A-phase and B-phase pulses and the level relationship between the A-phase and B-phase pulses. For example, if a falling edge occurs in the A-phase and the B-phase pulse is high, the lamp will rotate clockwise. If the B-phase pulse is high, the lamp will rotate counterclockwise. The encoder 514 converts the motion signal into an electrical signal, and a circuit receives the signal and adjusts the pulse width modulation to continuously brighten the brightness and color temperature.

[0063] According to one possible embodiment of the present application, commands for the sleep mode and the wake-up mode are input via the adjustment key 520. When the "sleep mode" button is pressed, the circuit system receives this command, performs timing via the microcontroller in the third circuit board 513, and controls the lighting assembly 200 to change the current magnitude of the lighting assembly 200 based on the command. As the current continues to decrease, the brightness of the lighting assembly 200 gradually decreases from bright to dark, until the current decreases until no light is emitted, creating a lighting environment suitable for bedtime. When the "wake-up mode" button is pressed, the power supply current of the lighting assembly 200 gradually increases, and the light gradually increases from dark to bright, eventually reaching the brightest state determined by the circuit design, achieving a gentle wake-up effect for the user.

[0064] In terms of timing length range adjustment, the timing function of the rotatable sleep lamp has different timing length ranges, each timing length range corresponding to a different time length, including but not limited to 4 hours, 6 hours, 8 hours, etc. When a user selects a timing length range, e.g., 6 hours, and an operation mode, e.g., the wake-up mode, the timing circuit of the sleep lamp begins to operate.

[0065] According to one possible embodiment of the present application, as shown in FIG. 12 , the microcontroller is a microcontroller MCU, and the control component 500 is connected to the control module, which includes the microcontroller MCU, a rotary encoder EC11, at least three mode selection buttons, i.e., a first button SW1, a second button SW2, and a third button SW3, and two status indicators, i.e., a first indicator LED1 and a second indicator LED2. The first button SW1 is configured as a wake-up mode selection key, the second button SW2 is configured as a power switch button, and the third button SW3 is configured as a sleep mode selection key. The first indicator LED1 controls a green light and is connected to the microprocessor MCU of the control module and configured to indicate a timing operating state. The second indicator LED2 controls a yellow light and is connected to the microprocessor MCU of the control module and configured to operate in a sleep mode.

[0066] 12, the microprocessor MCU includes a plurality of pins, and the first button SW1, the second button SW2, and the third button SW3 are directly connected to the microprocessor MCU via the pins, respectively. The anode of the first indicator lamp LED1 is connected to a first current-limiting resistor R14, the cathode of the first indicator lamp LED1 is connected to the microcontroller MCU, the anode of the second indicator lamp LED2 is connected to a second current-limiting resistor R15, and the cathode of the second indicator lamp LED2 is connected to the microcontroller MCU. The first current-limiting resistor R14 and the second current-limiting resistor R15 are used to limit the current flowing through the first indicator lamp LED1 and the second indicator lamp LED2 to ensure that the first indicator lamp LED1 and the second indicator lamp LED2 operate normally and prevent them from being burned out due to excessive current.

[0067] The microcontroller MCU includes a timing module, which is connected to the control module and has a built-in timer that is a multi-channel timer and is configured to provide a plurality of different timing time length ranges. For example, as shown in FIG. 12, the timing time length ranges of the present application include at least 5H, 6H, 7H, 8H, and 9H.

[0068] As shown in FIG. 12 , the built-in timer includes a fourth switch SW4, which is a multi-range switch connected to the timing key 522. The user can adjust the fourth switch SW4 by adjusting the timing key 522 to change the timing duration range of the timing mode. The built-in timer also includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a fifth resistor R5. The first resistor R1, the second resistor R2, the third resistor R3, the fourth resistor R4, and the fifth resistor R5 are all pull-up resistors, corresponding to different timing duration ranges. They ensure that the pulse signal remains stable at a high level in the circuit and act as current limiters. For example, when the timing duration range is selected as 5H and the fourth switch SW4 is operated, the fourth switch SW4 conducts the path associated with the first resistor R1, which pulls the corresponding pin high, transmitting a 5H timing duration range selection signal to the microcontroller MCU. The microcontroller MCU sets corresponding timing parameters according to the received signals, thereby realizing timing functions of different time lengths.

[0069] The circuit board of the control module integrates a DIM TO WARM unit for synchronously controlling the change of color temperature and brightness. As shown in Figure 13, the DIM TO WARM unit includes a first LED driving chip U1 and a second LED driving chip U2. The DIM TO WARM unit is provided with two sets of lighting elements with different color temperatures, a set of warm yellow light pulse width modulation (PWM_W) and a set of cool white light pulse width modulation (PWM_C). One end of the cool white light pulse width modulation (PWM_C) is connected to the first LED driving chip U1, the other end of the cool white light pulse width modulation (PWM_C) is connected to the microcontroller MCU, one end of the warm yellow light pulse width modulation (PWM_W) is connected to the second LED driving chip U2, and the other end of the warm yellow light pulse width modulation (PWM_W) is connected to the second LED driving chip U2 and the microcontroller MCU. The DIM TO WARM unit includes a first electrolytic capacitor EC1, a second electrolytic capacitor EC2, and a third electrolytic capacitor EC3. The electrolytic capacitors have charge / discharge characteristics that remove high-frequency ripple in the input voltage, such as noise mixed in during power transmission, and quickly release stored electrical energy when the load changes suddenly, ensuring voltage stability.

[0070] The dim to warm unit further includes a first inductor L1, a second inductor L2, and a first Schottky diode D1 and a second Schottky diode D2. The first inductor L1 and the second inductor L2 are used to store energy and smooth current. The inductor current's characteristic of not changing suddenly is used to smooth the current in the circuit when the circuit is turned off, reducing current fluctuations and improving circuit stability. When the circuit is turned off, the current in the first inductor L1 and the second inductor L2 does not change suddenly, generating back electromotive force. The first Schottky diode D1 and the second Schottky diode D2 conduct forward, providing a continuous path for the inductor current and limiting the back electromotive force within a safe range to protect the circuit.

[0071] Furthermore, both the first LED driver chip U1 and the second LED driver chip U2 include a DIM pin, which is a dimming control pin primarily used to adjust the LED brightness. The DIM pin receives a pulse-width modulation signal, which is a square-wave signal with alternating high and low levels at different time intervals. When the DIM pin of the LED driver chip receives the pulse-width modulation signal, the internal circuit of the LED driver chip adjusts the magnitude of the current output to the LED based on the duty ratio of the pulse-width modulation signal, i.e., the percentage of high-level duration in one pulse-width modulation period, thereby adjusting the LED brightness. For example, when the duty ratio of the pulse-width modulation signal is 100%, the LED driver chip outputs the maximum current, and the LED emits light at maximum brightness. When the duty ratio is 0%, the output current is 0, and the LED is turned off. The microcontroller MCU programs the duty ratio of the pulse-width modulation signal to dynamically adjust the LED brightness in real time. The microcontroller MCU controls the brightness ratio of the two sets of beads using warm yellow light pulse width modulation (PWM_W) and cool white light pulse width modulation (PWM_C), respectively. By adjusting the mix of strong and weak brightness, any color temperature from 1900K to 5000K can be synthesized. The rotary encoder EC11 is used to enter the DIM TO WARM adjustment mode. When rotated clockwise, it sends a signal to the control module to increase brightness and color temperature, and when rotated counterclockwise, it sends a signal to the control module to decrease brightness and color temperature, realizing continuous adjustment from the lowest brightness and lowest color temperature to the highest brightness and highest color temperature.

[0072] In one possible embodiment of the present application, as shown in Figure 12, when setting the timing operation mode, the first button SW1 is triggered to turn on the first indicator LED1, and after the preset time, the light gradually changes from 10% brightness and 1900K color temperature to 100% brightness and 5000K color temperature within one hour, and then remains the same. When setting the power-on / shutdown mode, the second button SW2 is pressed for two seconds to turn on the power, i.e., the brightness increases to 60% and the color temperature increases to 3000K, and then changes to the gradation, or to shut down, i.e., the current state changes to the gradation and then turns off, both of which take two seconds. When setting the sleep mode, the third button SW3 is triggered to turn on the second indicator LED2, and the brightness automatically adjusts to not exceed 60%, and after the preset time, the light gradually changes to the gradation and then turns off.

[0073] The timing module's timing time length range includes multiple timing time length ranges. In wake-up mode, a brightness gradation change is automatically initiated upon completion of timing. The first indicator light LED1 lights up during timing activation and turns off after the brightness gradation change is completed. The second indicator light LED2 remains lit during the sleep mode activation period until the rotatable sleep lamp is turned off.

[0074] As shown in Figure 12, the first button SW1, the second button SW2, and the third button SW3 are each connected to pins of the microcontroller MCU. The second button SW2 needs to detect a 2-second press, and the microcontroller MCU firmware needs to implement button timing judgment logic. The EC11 rotary encoder needs to connect two pins, and a hardware jitter elimination circuit is combined to detect clockwise / counterclockwise rotation to adjust brightness and color temperature in DIM TO WARM mode. The first indicator lamp LED1 and the second indicator lamp LED2 can be directly driven by the microcontroller MCU. The lighting module uses a pulse-width modulation dimming solution. Color temperature control requires two pulse-width modulations to control warm white light and cool white light, respectively, and adjusts the color temperature according to the light mixing ratio.

[0075] For example, the preset time of the timing module is 5 hours. Pressing the first button SW1 once briefly wakes up the timing function. The microcontroller MCU starts the 5-hour timer and remains in standby mode for the first four hours. The light change begins one hour before the end of the timer, i.e., four hours into the timer, and the circuitry begins to operate. The light changes in a one-hour brightness gradient, linearly changing from 10% brightness and 1900K color temperature to 100% brightness and 5000K color temperature within one hour. The sleep mode offers an adjustable timing time range, including but not limited to 4-hour, 6-hour, and 8-hour options. The light automatically changes in a gradient and turns off when the preset time arrives. In the wake mode, the light changes in a gradient from dim to bright, reaching its brightest state when the preset time arrives. Pressing the third button SW3 once briefly activates the sleep mode, forcing the brightness to be limited to ≦60% and automatically turning off after 30 minutes. The awake and sleep modes share the same time and duration range settings, but implement opposite lighting change processes. All lighting changes are smooth gradations without step changes in brightness or color temperature. The second button, SW2, controls system startup and shutdown. When pressed for 2 seconds to power on, the lighting will change gradually from 5% to 60% brightness and 3000K color temperature within 2 seconds.
