In the rapidly evolving world of automotive technology, lighting systems play a crucial role in safety and design. High luminous automotive lighting not only enhances visibility but also contributes to the aesthetic appeal of vehicles. As cars become more advanced, the demand for efficient and adaptable lighting solutions grows, challenging engineers to balance brightness, heat management, and energy consumption.
Professionals face numerous challenges in this field, including managing heat dissipation in compact spaces and achieving precise light distribution. The integration of advanced materials and innovative designs is necessary to address these issues, ensuring that lighting systems perform reliably under varying conditions without compromising on safety or functionality.
This webpage explores a range of solutions, such as integrated heat dissipation structures and multifunctional light assemblies. These innovations improve thermal management, enhance luminosity, and allow for flexible light distribution. By implementing these strategies, automotive lighting systems can achieve higher performance and efficiency, meeting the needs of modern vehicles while maintaining safety and style.
1. Integrated Heat Dissipation Structure for Automotive LED Headlights with Combined Radiator, Heat Pipes, and LED Board
SHENZHEN AURORA TECHNOLOGY LIMITED, 2023
Heat dissipating structure for automotive LED headlights to improve brightness, power, and lifetime while keeping the lights cool. The structure integrates the radiator, heat pipes, and LED board into a single unit to efficiently transfer heat from the LEDs to the fins. This eliminates the need for separate parts that can compromise heat dissipation. The integrated structure allows quick heat transfer and dissipation, reducing LED temperatures to improve brightness and longevity. The design also enables higher-power LEDs without overheating. By welding the parts together, heat is directly conducted from the LEDs to the fins. This ensures better heat transfer compared to separate components.
2. Integrated Headlight Assembly with Combined High and Low Beam LED Modules and Rotatable Support
Foshan Sunway Auto Electrical Co., Ltd, 2022
Motor vehicle headlight design that combines main high beam and secondary low beam functions in a single headlight. The headlight has a power supply driver, structure modules with LEDs, a light guide element, a reflector, and a heat sink. The secondary LEDs are surrounded by the light guide element. The main LED is in a through hole. This allows the secondary LEDs to diffuse light through the guide and reflector for low beams. The main LED provides high beam intensity. The driver controls both. Adjustable support rotates the LED positions for customization.
3. Vehicle Lighting Device with Pivotable Reflectors for Independent Sub-Light Distribution Adjustment
ZIZALA LICHTSYSTEME GMBH, 2016
A lighting device for vehicles like headlights that allows independent orientation of sub-light distributions from multiple light units to improve overall light distribution. The device has pivotable reflectors mounted on a fixed body. This allows adjusting the orientation of each sub-light distribution produced by the corresponding light unit. The pivoting reflectors can be fixed in a desired position. The body has separate vertical and horizontal sections with reflector pivot points. This enables independent vertical and horizontal adjustment. The reflectors can be formed as a single unit with the pivot holder.
4. Vehicle Headlight System with Central and Peripheral White LED Arrays Featuring Enhanced Scotopic/Photopic Ratio
STANLEY ELECTRIC CO., LTD., 2013
A vehicle headlight design that improves visibility and safety at night by facilitating earlier awareness of peripheral objects. The headlight uses white LEDs with enhanced blue light components (higher scotopic/photopic ratio) to illuminate the central area of the road. The blue-rich light stimulates rod cells for better peripheral vision. For the outer areas, regular white LEDs are used. This provides earlier awareness of objects in the peripheral vision, reducing reaction times and missing objects. The central white LED has a lower blue content to prevent glare.
5. LED Chip with Enhanced Brightness Through Internal Light Recycling and Scattering Mechanisms
Frank Shum, 2013
Increasing the brightness of LED lights by using techniques like recycling light within the LED chip, scattering light inside the chip, and reducing the angular spread of the emitted light. The goal is to make the LED source itself brighter, rather than just increasing optical power, by preventing light loss, trapping, and scattering. This allows smaller, more compact optics to be used and enables applications like high-brightness headlights, projectors, and flashlights with florescent-like power using smaller LED sources.
Headlights can now attain increased luminance and efficiency because of advances in automobile lighting systems, including dual-function LED designs, integrated heat dissipation systems, and methods for improving LED brightness. These developments have had a direct impact on improving road visibility and driving safety generally at night.
