Technical Field

[0002] Existing lighting and defogging equipment generally suffers from independent functions and cumbersome control. For example, traditional bathroom lighting requires manual adjustment of brightness and color temperature, while defogging functions often rely on manual switches or timers, failing to automatically trigger based on ambient fog concentration, leading to energy waste or untimely defogging. In the automotive field, traditional fog lights lack environmental adaptive adjustment capabilities, requiring drivers to manually switch light modes, posing a safety hazard. Furthermore, landscape lights and streetlights are prone to fogging in humid environments, affecting their illumination. Therefore, we propose an intelligent lighting defogging control system.

[0055] The color temperature MOS driver module 4 is connected to the light strip 5, and the microcontroller 3 controls the brightness and color temperature of the light strip 5 through the color temperature MOS driver module 4.

[0056] The panel backlight module 9 is directly controlled by the microcontroller 3;

[0057] The microcontroller 3 adjusts the brightness and color temperature of the light strip 5 by controlling the color temperature MOS driver module 4; the panel backlight module 9 is directly controlled by the microcontroller 3 to provide backlight for the operation interface.

[0058] The defogging module includes a defogging MOS drive module 7 and a defogging device 8, which are used to perform defogging operations;

[0059] The defogging MOS drive module 7 is connected to the defogging device 8, and the microcontroller 3 controls the start and stop of the defogging device 8 through the defogging MOS drive module 7;

[0060] Composed of a defogging MOS drive module 7 and a defogging device 8, when the infrared processing chip 12 detects that the fog concentration exceeds the standard through the infrared receiving module 14, it triggers the microcontroller to start the defogging MOS drive by outputting the defogging signal unit 10, thus starting the defogging device.

[0061] The sensing and interaction module includes a touch sensing interface module 6, an infrared processing chip 12, an infrared transmitting module 13, and an infrared receiving module 14, which are used to collect user operation signals and environmental fog data.

[0064] The touch sensing interface module 6 receives user operation signals; the infrared processing chip 12 monitors the ambient fog in real time through the infrared transmitting module 13 and the infrared receiving module 14 to achieve automatic sensing control.

[0065] like Figure 1-15 As shown, the workflow of the intelligent lighting defogging control system includes:

[0066] Power supply:

[0067] An external DC power supply, such as 12V, is connected to the system through DC power input 1. The input DC to 5V module 2 outputs a stable 5V voltage through its internal step-down circuit, such as the U1 chip, to power the microcontroller 3 and the 5V to 3.3V module 11.

[0068] The 5V to 3.3V module 11 converts 5V to 3.3V through a linear regulator or DC-DC converter such as the LM1117 chip to provide the operating voltage for the infrared processing chip 12.

[0069] Lighting control:

[0070] Manual mode: When the user touches the touch sensing interface 6, it triggers a resistor voltage divider or capacitor sensing signal, which is then filtered and transmitted to the microcontroller 3.

[0071] After the microcontroller 3 analyzes the signal, it outputs a PWM signal to the color temperature MOS driver 4.

[0072] Adjust the PWM duty cycle to control the brightness of LED strip 5; for example, the higher the duty cycle, the brighter the LED strip.

[0073] By switching PWM channels such as PWM_C / PWM_W to control the color temperature of the light strip 5, the switching between cool light 6500K and warm light 3000K can be achieved.

[0074] The microcontroller 3 synchronously controls the backlight 9's on / off state and brightness, such as automatically enhancing the backlight in low-light environments to improve operational visibility;

[0075] Automatic defogging:

[0076] The infrared processing chip 12 continuously emits infrared signals, such as those with a wavelength of 940nm, via the infrared transmitter 13, and the infrared receiver 14 monitors the intensity of reflected or transmitted signals in real time.

[0077] When the ambient fog concentration increases, the infrared signal is attenuated due to fog scattering. The infrared receiver 14 detects that the signal strength is lower than the threshold and triggers the comparator or ADC module inside the infrared processing chip 12.

[0078] The infrared processing chip 12 sends an interrupt request to the microcontroller 3 by outputting a defogging signal 10. The microcontroller 3 immediately turns on the defogging MOS driver 7 and turns on the defogging device 8, such as the heating resistance wire, until the infrared receiver 14 detects that the fog concentration has dropped to a safe range.

[0079] When there is fog on the mirror surface, the infrared processing chip 12 sends a signal to start the defogging function, and the microcontroller 3 sends a signal to the output defogging unit 10 to start the defogging function. When the fog disappears, the defogging function is turned off.

[0080] After the defogger is turned on, it will be turned off after a delay.
