Innovations in High Luminous Automotive Lighting

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.

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.

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.

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.

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.
