Description

Adaptive Transparent LED Matrix Surface Vehicle Lighting System TECHNICAL FIELD This invention enables the active and functional operation of exterior surfaces (hood, grille, bumper or windshield) in motor vehicles. Micro-LED technology, graphene, enables it to be transformed into an invisible source of light. laminated glass supported by transparent electrodes and autonomous fault tolerance algorithms. It relates to the integrated adaptive transparent vehicle lighting system. STATE OF THE ART In the automotive world, vehicle lighting systems (headlights) are related to vehicle design and aerodynamics. a voluminous space composed of mechanical and electronic components that imposes significant restrictions on it They are (bulky) structures. Current headlight systems use halogen, standard LED, or gas discharge as light sources. It uses lamps and movable components for light direction (Adaptive Driving Beam - ADB). It requires lenses, mirrors, or mechanical shutters. These mechanical components both increase the risk of failure and increase the weight and volume of the system. It is growing. In addition, current technology exposes vehicles to headlights, flying stones, moisture, corrosion, and oxidation. It is quite vulnerable to external factors such as these. Headlights exposed to water or moisture may experience yellowing, oxidation, and a significant reduction in LED lifespan in their interior parts. Shortenings are occurring. However, existing methods for obtaining screens or light on transparent surfaces... ITO (Indium Tin Oxide) is mostly used in systems for electrical conduction and heat management purposes. Layers are used. However, ITO structures are fragile, and problems arise when high illumination power (lumens) is reached. by failing to dissipate the intense heat load, the system experiences "thermal breakdown". is happening. Finally, in current headlight systems, when a single LED blows or short-circuits, all The headlight or a large module needs to be replaced; this makes repair costs incredibly high. This increases the risk to a certain degree and creates a security vulnerability (loss of lighting). THE PURPOSE OF THE INVENTION The primary purpose of the invention is to overcome the dependence on traditional headlight housings and shaping mechanical parts. a transparent design that aerodynamically enhances the front of the vehicle by completely eliminating the need for it. An adaptive headlight system embedded in laminated hardware, with fault tolerance (self-healing). to accomplish. 2 Another objective of the invention is to place flexible graphene electrode layers between two glass layers. By combining them using the "vacuum autoclave" method, the LEDs are completely protected from contact with air and moisture. By cutting off (by resetting) and providing mechanical protection, the module lifespan is extended to over 100,000 hours. to remove. Another objective of the invention is to integrate a "Thermal Stress Damping Layer" into the structure, sudden temperature changes ranging from system freezing points to extreme heat or engine temperature Its purpose is to ensure structural integrity against changes (thermal shocks). One of the main aims of the invention is to replace mechanical coolers with Chemical Vapor Deposition. Using graphene-based transparent conductive electrodes produced by (CVD) method, the thermal system to create an active cooling surface function that distributes its load across the body; at the same time this graphene layered panel with capacitive touch functionality (e.g., trunk opening when approaching the vehicle) to make a profit. Another aim of the invention is to transmit light not randomly, but according to homologation (UNECE R112 / R123). with the Total Internal Reflection (TIR) ​​principle which ensures that it is directed in accordance with standards Using micro-reflective (nano-printed / optical polymer) structures, mechanical parts It is possible to control the high / low beam (HDB) function programmatically without using it. Another aim of the invention is to eliminate the risk of "single-point failure"; malfunction In this case, nanoscale electronic fuses (e-fuses) isolate the short circuit, preventing damage. The field's function is to increase the power / angle value of the remaining neighboring micro-LEDs (Dynamic The goal is to provide a fail-safe lighting architecture that compensates for (Mapping / Compensation). DETAILED DESCRIPTION OF THE INVENTION In its most basic form, the invention is a micro-machine embedded between two layers of glass to provide light to a road. The graphene electrode layers, which house the LED matrix and provide thermal and electrical conductivity, are optical. micro-reflective units that provide control and an electronic control that manages fault tolerance. It is a lighting system with unit (8). The system described in the invention involves the production phase of flexible graphene electrode layers and micro-LEDs. the matrix is ​​formed between an outer glass layer and an inner glass layer using a "Vacuum Autoclave" process. It is obtained by combining them in an airless environment. Thanks to this embedded structure within laminated glass, micro-LEDs are protected from air, liquids, and moisture. Contact is completely severed (by resetting), oxidation is prevented, and the LED lifespan is extended to 100,000 hours. It is applied over the surface. It also provides armor against tooth decay, corrosion, and stone chips. 35 level of protection is provided. The invention features a customized thermal stress damping system integrated into the laminated glass structure. It has layers. The thermal stress relief layer absorbs heat as the ambient temperature drops to freezing in winter, affecting the matrix. "Thermal shock" is the term used to describe the extremely high temperatures reached due to the working temperature or the effect of the summer sun. by absorbing expansion and contraction forces in (thermal shock) situations, the system It maintains its mechanical resistance and structural integrity. The system's energy transmission and heat management are handled by Chemical Vapor, instead of traditional ITO components. This is achieved with a flexible graphene electrode layer produced by the CVD (cold deposition) method. Graphene, one of the materials with the highest thermal conductivity coefficient in the world, is microscopic. By acting as an active heat sink, it reduces the thermal load generated during the intense operation of the LEDs. It spreads evenly across the vehicle body (preventing thermal degradation / yellowing). Graphene electrode layers are used not only for lighting but also for vehicle panels (for example, the windshield or The hood is also designed to provide capacitive touch sensitivity. The user can see this from the outside. You can open the trunk by touching it, and you can see the charging status information via the light. The invention involves directing light to specific distances (50-100 meters) and focal points in accordance with standards. a photonic crystal integrated on a microscopic scale on its surface that enables the transmission of light or It contains free-form micro-reflective units. The micro-reflector unit consists of transparent micro-pyramids placed on top of each micro-LED, or It consists of parabolic troughs and uses Total Internal Reflection (TIR) ​​strategy to direct light to the target. It directs (collimation). The prismatic structures within this unit create a "low beam" effect by widening the light horizontally and narrowing it vertically. While emitting light, the spherical structures distribute the light over a wide area, creating a Daytime Running Light (DRL) effect. These structures create a diffuser effect, making the LED points visible to the driver when viewed from the outside. No, it allows him to see a homogeneous "wall of light". The system described in the invention complies with legal regulations (UNECE R112 / R123) for mechanical blinds. It performs Photometric Zoning (Pixel Duty Cycle) using software without the need for a sensor barrier. Data received from Lidar / Camera and other similar equipment on board is used for Electronic Control. It is covered in the unit. When a vehicle approaches from the opposite direction, or when a pedestrian crossing is detected, micro-LED pixels are positioned in that area. Pixel dimming is performed by scanning at speeds above 60 Hz per second. The system's main headlight element offers a white spectrum, while layered colored RGB LED films provide additional lighting. While the vehicle performs its functions such as turn signals, fog lights, welcome and farewell (animation), the headlights In this mode, it enables purely white lighting via a hardware lock. It provides security. One of the most fundamental innovations of the invention is fault management; "Distributed Lighting Architecture". It operates on three different levels based on this principle. The first stage is CAN-Bus Feedback Health Screening. By performing this procedure, if no current flows even when the LED is off, an "open circuit fault" is detected. In the second stage... Dynamic Compensation comes into play. 35 When a regional fault occurs, the electronic control unit monitors the area around the faulty part. It increases the brightness of the "neighboring LEDs" (by increasing the PWM value) and the micro-reflectors (6) 4 By utilizing the advantage of reflection, it prevents the formation of dark areas through software and light. It recalculates the distribution. If the percentage of malfunctions threatens the legal limits, a warning message is generated for the driver. Third At the next layer, the Fail-Safe protocol is activated, preventing any short circuits from occurring. Nanometric-scale electronic fuses (81 - e-fuses) that provide insulation in the circuit, faulty The microblock is isolated (quarantined) from the physical circuit within microseconds, and the system It prevents the entire structure from burning down. Thanks to its modular architecture, the relevant block can be repaired. A light intensity sensor integrated into the system detects obstacles such as snow and mud on the panel's outer surface. If it detects that it has switched off, it can legally increase the power factor of the existing micro-LEDs. It supports achieving the desired lighting intensity. A projection module, which can be added to the system upon request, displays micro-projections on graphene and laminated glass. Working with optical guidance principles via reflectors, it displays speed limit signs and navigation / direction arrows on the road. or data such as pedestrian warnings can be reflected using DLP tools. With Over-the-Air (OTA) software updates, the capabilities of the headlights (light pattern, etc.) can be improved. It can be updated without making any changes.
