Detailed Implementation
[0028] The core of this utility model is to provide a sunshade and its supplementary lighting circuit, which can adjust the brightness and intensity of the warm-colored supplementary lighting array and the cool-colored supplementary lighting array respectively by using the supplementary lighting adjustment parameters determined by the signal generation module, so that the supplementary lighting of the sunshade can adjust the brightness and color temperature, realize the intelligent supplementary lighting of the sunshade, and meet the supplementary lighting needs.
[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] For details, please see Figure 1 As shown, Figure 1 This is a schematic diagram of the supplementary lighting circuit for a sunshade disclosed in this utility model.
[0031] The supplementary lighting circuit of the sun visor includes a signal generation module 1, a processor 2, a first driving circuit 3, a second driving circuit 4, a warm-colored supplementary lighting array 5, and a cool-colored supplementary lighting array 6. The signal generation module 1 is connected to the input terminal of the processor 2. The output terminal of the processor 2 is connected to the input terminal of the first driving circuit 3 and the input terminal of the second driving circuit 4. The output terminal of the first driving circuit 3 is connected to the warm-colored supplementary lighting array 5. The output terminal of the second driving circuit 4 is connected to the cool-colored supplementary lighting array 6.
[0032] Specifically, signal generation module 1 sends the determined fill light adjustment parameters to processor 2. Processor 2 outputs a first control signal to first drive circuit 3 and a second control signal to second drive circuit 4 based on the fill light adjustment parameters. First drive circuit 3 generates a first current signal based on the first control signal, and controls the brightness and intensity of warm-colored fill light array 5 by the magnitude of the first current signal. Second drive circuit 4 generates a second current signal based on the second control signal, and controls the brightness and intensity of cool-colored fill light array 6 by the magnitude of the second current signal. The magnitude of the first current signal is positively correlated with the brightness and intensity of warm-colored fill light array 5, and the magnitude of the second current signal is also positively correlated with the brightness and intensity of cool-colored fill light array 6. Both the first and second control signals can be pulse signals.
[0033] As can be seen, this application uses the adjustment parameters of the fill light determined by the signal generation module 1 to adjust the brightness and intensity of the warm color fill light array 5 and the cool color fill light array 6 respectively, so that the fill light of the sun shade can adjust the brightness and color temperature, realize the intelligentization of the fill light of the sun shade and meet the fill light needs.
[0034] Based on the above embodiments:
[0035] Please refer to Figure 2 As shown, Figure 2 This is a schematic diagram of the supplementary lighting circuit for the first specific sunshade disclosed in this utility model.
[0036] As an optional embodiment, it also includes a third driving circuit 7 and an ultraviolet lamp array 8. The input terminal of the third driving circuit 7 is connected to the output terminal of the processor 2, and the output terminal of the third driving circuit 7 is connected to the ultraviolet lamp array 8.
[0037] Considering that the ultraviolet light intensity provided by the natural light or warm-colored supplementary light array 5 and the cool-colored supplementary light array 6 is relatively low, it may not be able to meet the supplementary lighting needs when high-intensity and stable ultraviolet light is required. When the supplementary light adjustment parameters require adjustment of the ultraviolet light, the processor 2 will output a third control signal to the third drive circuit 7 based on the supplementary light adjustment parameters. The third drive circuit 7 generates a third current signal based on the third control signal, and controls the brightness and intensity of the ultraviolet supplementary light array 8 by controlling the magnitude of the third current signal. The magnitude of the third current signal is also positively correlated with the brightness and intensity of the ultraviolet supplementary light array 8, and the third control signal can also be a pulse signal.
[0038] As can be seen, this embodiment adds a third driving circuit 7 and an ultraviolet supplementary light array 8, which can adjust the brightness and intensity of the ultraviolet supplementary light array 8 to meet the supplementary lighting requirements when there is a need to adjust the ultraviolet light by adjusting the parameters of the supplementary light.
[0039] As an optional embodiment, it also includes a touch screen and a UV camera, wherein the touch screen is attached to the mirror display and the UV camera is disposed inside the mirror display for detecting the image information of the mirror display when the touch screen is activated in the intelligent assisted makeup mode.
[0040] Many substances fluoresce under ultraviolet light, and UV cameras can capture images in the ultraviolet light band. Therefore, a UV camera is installed inside the mirror display screen, which also functions as a makeup mirror. The UV camera can detect the image information displayed on the mirror display screen. When the touchscreen activates the intelligent makeup assistance mode, the UV camera detects the image information on the mirror display screen. Users can then check the current level of sun protection makeup evenness or makeup removal cleansing based on the image information displayed on the mirror display screen, and adjust the makeup or makeup removal effect accordingly.
[0041] As can be seen, this embodiment is equipped with a touch screen and a UV camera. When the intelligent assisted makeup mode is activated on the touch screen, the UV camera can detect the image information on the mirror display screen and determine the areas that need to be concealed or modified based on the image information on the mirror display screen, thereby improving the makeup or makeup removal effect.
[0042] As an optional embodiment, the warm-color fill light array 5, the cool-color fill light array 6, and the ultraviolet fill light array 8 are all LED light arrays.
[0043] LED lights are characterized by high luminous efficiency and low power consumption, which can significantly reduce energy consumption and are suitable for long-term use. Moreover, LED lights can provide stable illumination, are not easily affected by voltage fluctuations, and ensure consistent lighting effects. In addition, LED lights can achieve precise control of brightness and color temperature by adjusting the current, adapting to different scene requirements.
[0044] Therefore, in order to ensure energy saving and stability while flexibly controlling the warm color fill light array 5, the cool color fill light array 6 and the ultraviolet fill light array 8, this embodiment uses an LED light array as the warm color fill light array 5, the cool color fill light array 6 and the ultraviolet fill light array 8.
[0045] Please see Figure 3 As shown, Figure 3 This is a schematic diagram of the supplementary lighting circuit for the second specific type of sunshade disclosed in this utility model.
[0046] As an optional embodiment, the signal generating module 1 is a light sensing module 9, which is connected to the input terminal of the processor 2 and is located on the back of the mirror display screen.
[0047] Specifically, the light sensor module 9 is located on the back of the mirror display screen, facing the windshield of the car. When the sun visor is folded down, the light sensor module 9 can detect the brightness and color temperature of the ambient light from the windshield, specifically the ambient light at the passenger side, and output these values to the processor 2. The processor 2 compares the ambient light brightness with a preset brightness threshold and the ambient light color temperature with a preset color temperature threshold. Based on the comparison results, it generates a first control signal and a second control signal, sending the first control signal to the first drive circuit 3 and the second control signal to the second drive circuit 4. The first drive circuit 3 adjusts the magnitude of the first current signal based on the first control signal, and the second drive circuit 4 adjusts the magnitude of the second current signal based on the second control signal, so that the brightness and color temperature of the warm-colored fill light array 5, the cool-colored fill light array 6, and the ambient light reach the preset brightness threshold and preset color temperature threshold, respectively. The preset brightness threshold and preset color temperature threshold can be adjusted by the user according to their own makeup preferences.
[0048] As can be seen, this embodiment uses the light sensing module 9 to detect the brightness and color temperature of the ambient light, so that the supplementary light can be automatically adjusted to the appropriate brightness and color temperature for the user in different environments, thus meeting the user's supplementary lighting needs.
[0049] Please see Figure 4 As shown, Figure 4 This is a schematic diagram of the supplementary lighting circuit for the third specific sunshade disclosed in this utility model.
[0050] As an optional embodiment, the signal generation module 1 is a manual control module 10, which is connected to the input terminal of the processor 2.
[0051] Specifically, users can manually adjust the brightness and color temperature of the fill light to suit their own needs through the control module 10 and save the settings. They can also select from preset lighting modes, including but not limited to the intelligent makeup assistance mode. When the user manually sets the brightness and color temperature thresholds, processor 2 directly generates a first control signal and a second control signal based on these thresholds. The first control signal is sent to the first drive circuit 3, and the second control signal is sent to the second drive circuit 4. The first drive circuit 3 adjusts the magnitude of the first current signal based on the first control signal, and the second drive circuit 4 adjusts the magnitude of the second current signal based on the second control signal, so that the brightness and color temperature of the warm-colored fill light array 5 and the cool-colored fill light array 6 reach the brightness and color temperature thresholds. When the user manually selects any preset lighting mode, processor 2 directly generates a first control signal and a second control signal based on that preset lighting mode. The first control signal is sent to the first drive circuit 3, and the second control signal is sent to the second drive circuit 4. The first drive circuit 3 adjusts the magnitude of the first current signal based on the first control signal, and the second drive circuit 4 adjusts the magnitude of the second current signal based on the second control signal, so that the brightness and color temperature of the warm-colored fill light array 5 and the cool-colored fill light array 6 reach the brightness and color temperature of the preset lighting mode. The manual control module 10 can be a touchscreen, which is attached to the mirror display screen.
[0052] As can be seen, in this embodiment, the manual control module 10 is used as the signal generation module 1, which can provide real-time adjustment feedback to make personalized settings according to the supplementary lighting needs and adapt to different lighting scenarios.
[0053] As an optional embodiment, the signal generation module 1 includes a manual control module and a light sensing module; the manual control module is connected to the input terminal of the processor 2 and is used to preset the brightness threshold and color temperature threshold, or to select a preset lighting mode; the light sensing module is connected to the input terminal of the processor 2 and is located on the back of the mirror display screen, and is used to detect the brightness and color temperature of the ambient light.
[0054] Specifically, users can manually adjust the brightness and color temperature of the supplementary light to their preferred settings using the control module and save the settings, or select from preset lighting modes. When the sun visor is folded down, the light sensor module detects the brightness and color temperature of ambient light from the car's windshield, specifically the ambient light at the passenger side, and outputs these values to processor 2. Processor 2 compares the ambient light brightness with a preset brightness threshold, the ambient light color temperature with a preset color temperature threshold, and generates a first comparison result. Alternatively, processor 2 compares the ambient light brightness with the brightness, ambient light color temperature, and color temperature under a preset lighting mode, generating a second comparison result. Then, based on either the first or second comparison result, a corresponding first control is generated. The system generates a control signal and a second control signal, and sends the first control signal to the first drive circuit 3 and the second control signal to the second drive circuit 4. The first drive circuit 3 adjusts the magnitude of the first current signal based on the first control signal, and the second drive circuit 4 adjusts the magnitude of the second current signal based on the second control signal, so that the brightness and color temperature of the warm color fill light array 5, the cool color fill light array 6 and the ambient light reach the preset brightness threshold and preset color temperature threshold, or so that the brightness and color temperature of the warm color fill light array 5, the cool color fill light array 6 and the ambient light reach the brightness and color temperature of the preset lighting mode.
[0055] As can be seen, the manual control module provides an intuitive adjustment method, while the light sensor module enables automatic adjustment. The combination of the two can meet the diverse lighting needs of users, providing an intelligent, flexible, and efficient way to adjust brightness and color temperature.
[0056] Please see Figure 5 As shown, Figure 5 This is a schematic diagram of the supplementary lighting circuit for the fourth specific sunshade disclosed in this utility model.
[0057] As an optional embodiment, it also includes an angle sensing module 11, which is connected to the processor 2 and is located inside the sunshade body.
[0058] During makeup application, the sun visor will flip down from the horizontal position on the roof. Since the angle sensing module 11 is located inside the sun visor body, the position of the angle sensing module 11 will change accordingly when the position of the sun visor body changes. Therefore, the usage status of the sun visor can be determined by the real-time X-axis data, Y-axis data and Z-axis data of the angle sensing module 11.
[0059] Specifically, the angle sensing module 11 transmits its current X-axis, Y-axis, and Z-axis data to the processor 2. The processor 2 compares the current X-axis, Y-axis, and Z-axis data with preset X-axis, Y-axis, and Z-axis data. If the angle at which the sun visor body tilts down, as represented by the current X-axis, Y-axis, and Z-axis data, is less than the preset opening angle, the processor 2 will turn off the supplementary light by default. The preset X-axis, Y-axis, and Z-axis data are the X-axis, Y-axis, and Z-axis data corresponding to when the sun visor body tilts down to the preset opening angle. The preset opening angle can be manually set. For example, if the preset opening angle is 60 degrees, when the sun visor body tilts down to less than 60 degrees, the processor 2 will turn off the supplementary light by default.
[0060] As can be seen, this embodiment uses the angle sensing module 11 to determine the usage status of the sun visor in real time using its own X-axis data, Y-axis data and Z-axis data. While realizing the automatic activation of the supplementary light, it can turn off the supplementary light when it is not needed, thereby reducing energy consumption and lowering operating costs.
[0061] This utility model also provides a sun visor, including the supplementary lighting circuit of the sun visor as described above, as well as a sun visor body and a mirror display screen. The supplementary lighting circuit of the sun visor is disposed inside the sun visor body, and the mirror display screen is embedded on the side of the sun visor body that faces away from the windshield.
[0062] Furthermore, for an introduction to the sunshade provided by this utility model, please refer to the above embodiment of the supplementary lighting circuit of the sunshade; this utility model will not be described again here.
[0063] As can be seen, this application uses the signal generation module 1 in the sun shade to determine the adjustment parameters of the supplementary light to adjust the brightness and intensity of the warm-colored supplementary light array 5 and the cool-colored supplementary light array 6 respectively, so that the supplementary light of the sun shade can adjust the brightness and color temperature, realize the intelligent supplementary light of the sun shade and meet the supplementary light needs.
