Updated:
Automotive lighting has evolved from simple beams to sophisticated systems offering user control and adaptability. Today's vehicles feature lights that adjust intensity, color, and direction, enhancing both safety and aesthetics. These advancements address the growing need for customizable and responsive lighting in diverse driving conditions.
Professionals face the challenge of integrating complex lighting systems without compromising reliability or regulatory compliance. Balancing user control with safety standards requires innovative designs and precise engineering. Ensuring seamless operation while adapting to different environments is a key obstacle in this domain.
This webpage explores solutions like segmented LED matrices, independently controllable segments, and adaptive control systems. These approaches enhance visibility, reduce glare, and offer drivers greater control over their vehicle's lighting. By employing these strategies, professionals can achieve improved performance and compliance with minimal complexity.
1. Adaptive Vehicle Headlights with Segmented LED Matrices and Pre-Stored Intensity Data Sets for Smooth Transitioning
ZKW Group GmbH, 2023
Smoothly transitioning between different light functions for adaptive vehicle headlights that use segmented LED matrices. The headlights are controlled by selecting and superimposing pre-stored data sets specifying segment intensities for different light distributions. A smoothing function limits changes to avoid sudden transitions exceeding a maximum rate. This allows seamless switching between light distributions like dipped and full beams without requiring complex real-time calculations.
2. Vehicle Lighting System with Independently Controllable Segments and Regulatory Compliance Control
AUDI AG, 2023
A vehicle lighting system that allows customizable exterior lighting while meeting legal requirements for light intensity. The lighting system has exterior lights with independently controllable segments. The segments can be individually controlled to create different lighting patterns and graphics. The control device operates the segments in different modes to meet lighting requirements like total intensity while providing flexibility and customization. Users can create their own lighting modes via an interface, but the control prevents them from violating requirements.
3. Optical System with Dual Colored Layers for Multidirectional Light Propagation Control
GM GLOBAL TECHNOLOGY OPERATIONS LLC, 2023
An optical system for multidirectional light propagation and control uses two colored layers placed between cavities to control the transmission, reflection, absorption, and direction of light within and through the cavities.
4. Headlamp with Stacked Light-Emitting Cell Array and Image-Based Dynamic Control System
SAMSUNG ELECTRONICS CO., LTD., 2023
A headlamp with a unique cell array design and control system that enables dynamic control of light emission based on captured images to provide adaptive illumination and avoid dazzling other drivers. The headlamp has three stacked regions of light-emitting cells, with smaller cells stacked on larger ones. This allows finely adjustable illumination by independently controlling the stacked cell regions. An image sensor captures the forward view and sets the emission region. Controllers and drivers turn on/off the cells as needed.
5. Automotive Lamp with Multi-Color Light Sources and Controlled Light Guide Panel
KOITO MANUFACTURING CO., LTD., 2023
Automotive lamp with multi-color light sources for creating flexible and dynamic lighting effects. The lamp has multiple light-emitting units on one end of a light guide panel, each with two differently colored light sources. An onboard controller can control the light sources to vary their luminance and color over time, allowing for changing lighting effects like fading, color shifting, etc.
6. Vehicle Spotlight System with Non-Invasive Electronic Control Assembly and Sensor-Based Actuation
WHELEN ENGINEERING COMPANY, INC., 2023
A spotlight system for vehicles provides intuitive control of a spotlight without requiring drilling holes in vehicle pillars. The system has a control assembly inside the vehicle that replicates the look and feel of traditional mechanical controls and a spotlight assembly mounted outside the vehicle that responds to electronic signals from the control assembly. The control assembly has sensors to detect the rotation of the handle and shafts, and a microcontroller converts those movements into spotlight control signals. The spotlight assembly has motors that move the spotlight in response to the control signals.
7. Vehicle Signal Lights with RGB LED Array and Adaptive Control for Multi-Position Compliance
DEERE & COMPANY, 2023
Vehicle signal lights that comply with on-road vehicle signal light requirements and can be controlled to meet lighting requirements for various vehicle light positions while also providing flexibility for lighting applications in the off-road environment. The lights use a plurality of RGB LEDs behind a clear lens. A controller monitors vehicle conditions and sends lighting commands to activate one or more LEDs based on the conditions. This allows a single light fixture to meet different lighting requirements by controlling the LED colors.
These developments show how user-controlled automotive lighting systems are developing in sophistication. More advanced solutions that enhance driver's comfort, safety on the road, and customization can be expected as automobile lighting technology advances.
