Description

[0001] DESCRIPTION

[0002] Dynamic light adjustment device for vehicle windows

[0003] OBJECT OF THE INVENTION

[0004] The invention, as the title of this specification indicates, is a dynamic light adjustment device for vehicle windows. It is an innovation that offers advantages previously unknown within current techniques.

[0005] TECHNICAL SECTOR

[0006] The present invention falls within the sector of diverse industrial techniques and transport, in windows, windshields and accessories for them, as well as in anti-glare equipment combined with windows or windshields.

[0007] STATE OF THE ART

[0008] The present invention arises from observing that photosensitive people experience difficulties driving, especially at night or in conditions of intense light, such as direct solar radiation.

[0009] This sensitivity to light can cause glare from oncoming headlights or from exposure to the sun, affecting their ability to see clearly and hindering safe driving.

[0010] Furthermore, in everyday driving situations, this problem increases the risk of accidents, as the light intensity can cause blurred or dazzling vision.

[0011] Accordingly, this invention presents a dynamic light adjustment device for vehicle windows that minimizes glare and improves visibility, in order to ensure safer and more comfortable driving.

[0012] Currently, there is no known existence of any dynamic light adjustment device for vehicle windows that presents structural and constitutive technical characteristics equal or similar to those described in this descriptive memorandum, as claimed.

[0013] DESCRIPTION OF THE INVENTION

[0014] The object of the present invention is the creation of a dynamic light adjustment device for vehicle windows that provides a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany the present description.

[0015] The present invention describes a dynamic light adjustment device for vehicle windows comprising a front vehicle window incorporating a light management system and protective elements. These components work together to automatically adjust the opacity of the front window according to the received light intensity, providing protection against the effects of glare and solar radiation.

[0016] This invention solves the problem of glare and solar radiation that affect visibility while driving, especially in bright light conditions.

[0017] This innovation is highly beneficial, as it provides an effective tool to address the challenges of photosensitivity while driving.

[0018] By dynamically regulating the opacity of the windshield, the negative effects of glare and intense sunlight are minimized, contributing to a more comfortable and safer driving experience, especially in changing light conditions.

[0019] The windshield of a vehicle uses tinting glass, such as photochromic or electrochromic glass, which allows its opacity to be adjusted according to the lighting conditions. This feature provides automatic protection against bright light, including glare at night.

[0020] The light management system, for its part, is composed of ambient light sensors and a brightness control processor.

[0021] These sensors monitor lighting conditions beyond the adaptability of the photochromic or electrochromic material, allowing precise adjustments to opacity and control of received light, adapting to the intensity of LED lights from other vehicles or to solar radiation throughout the day.

[0022] Ambient light sensors are positioned along the edges of the vehicle's windshield, typically the top and sides, and are configured to detect variations in light intensity. When these changes are detected, the sensors send signals to the brightness control processor, which adjusts the opacity in real time.

[0023] This processor is preferably located on the upper edge of the windshield or in the dashboard area, ensuring that adjustments are made quickly and accurately to improve the driver's visibility.

[0024] Furthermore, the device's protective elements preferably include a UV and anti-glare protective coating applied to the outer surface of the vehicle's windshield. This coating is designed to block ultraviolet radiation and reduce reflections that could interfere with the driver's visibility, thereby improving safety in conditions of high brightness and direct UV radiation, even when the vehicle is off and the light management system is not operating.

[0025] The lighting management system connects to the vehicle's electrical system, powering the control processor, light sensors, and electrochromic lenses, ensuring continuous and independent operation. While less desirable, it can have its own battery.

[0026] This system is also linked to a manual control interface located on the vehicle's dashboard, giving the driver the ability to activate, deactivate, or manually adjust the tint of the windshield according to their needs. For example, a person with photosensitivity can activate enhanced protection.

[0027] In summary, this device automatically adjusts the opacity of the vehicle's windshield according to the light intensity, providing protection against glare and solar radiation without the need for user intervention.

[0028] EXPLANATION OF THE FIGURES

[0029] To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by a figure in which, for illustrative and non-limiting purposes, the following has been represented.

[0030] Figure 1 shows a perspective view of the dynamic light adjustment device for vehicle windows. PREFERRED EMBODIMENT OF THE INVENTION.

[0031] The dynamic light adjustment device for vehicle windows, the subject of this invention, comprises a vehicle windshield (1) incorporating a light management system (2) and protective elements (3). These components work cooperatively to automatically adjust the opacity of the vehicle windshield (1) according to the received light intensity, thus providing protection against the effects of glare and solar radiation, which improves driver safety and comfort.

[0032] In a preferred embodiment, the vehicle's windshield (1) uses tinting glass, such as photochromic or electrochromic glass, which allows the glass's opacity to be adjusted according to the lighting conditions, including nighttime glare. This automatic adjustment provides efficient protection under various lighting conditions.

[0033] Preferably, the light management system (2) includes ambient light sensors and a brightness control processor. These sensors monitor light conditions beyond what the photochromic or electrochromic material of the vehicle's windshield (1) is capable of detecting. Thus, the system can make precise adjustments to the opacity, taking into account the intensity of LED lights from other vehicles or solar radiation at different times of day, ensuring safe and uninterrupted driving.

[0034] In another preferred mode, ambient light sensors are positioned on the upper and side edges of the vehicle's windshield (1). These sensors are configured to detect variations in light intensity and send signals to the brightness control processor, allowing for efficient regulation of opacity changes.

[0035] In another preferred configuration, the brightness control processor is located on the upper edge of the vehicle's windshield (1) or in the vehicle's dashboard area. This processor is designed to receive information from the ambient light sensors, allowing it to adjust the opacity of the vehicle's windshield (1) in real time, quickly adapting to changes in light levels.

[0036] In another preferred mode, the protective elements (3) comprise, among other elements, a UV and anti-reflective protective coating applied to the outer surface of the vehicle's windshield (1). This coating is designed to block ultraviolet radiation and reduce reflections that interfere with the driver's visibility, thereby improving driver safety in conditions of high brightness and direct UV radiation, even when the vehicle is switched off and the light management system (2) is not operational.

[0037] Preferably, the light management system (2) is connected to the vehicle's electrical system, which allows the control processor, light sensors and electrochromic crystals to be powered, ensuring continuous and autonomous operation of the device without the need for additional external sources.

[0038] Preferably, the light management system (2) is connected to a manual control interface located on the vehicle panel, allowing the driver to manually activate, deactivate, or adjust the change in tint of the vehicle's front windshield (1), thus providing additional control for specific situations requiring a customized adjustment.

[0039] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field may understand its scope and the advantages that derive from it, it being noted that, within its essentiality, it may be put into practice in other modes of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought provided that its fundamental principle is not altered, changed or modified.
