Advancements for Improved Automotive Lighting Distribution

Vehicle lamp system with multi-color light sources that can improve visibility in bad weather conditions. The lamp has at least two light sources that project different colored lights. The light sources are aimed such that the different colored lights partially or fully overlap at the projection target. This can create a composite light of mixed colors that can enhance visibility in conditions like fog, rain, or snow compared to single-color LED lamps.

This vehicle lamp uses a specific arrangement of first and second LEDs to achieve the desired luminance distribution pattern. The lamp has one central LED surrounded by four outer LEDs on a substrate. The luminance from these LEDs is arranged to have a central high-intensity region surrounded by progressively lower-intensity regions. This provides a balanced and uniform overall luminance distribution. The lamp achieves this using specific LED positions, sizes, and intensities.

Vehicle lamps are capable of dynamically changing their light distribution pattern to create different lamp images. The lamp has multiple light source modules that form different light patterns. A movement mechanism moves one light source module while another rotates to vary the light distribution. This dynamically converts the overall light pattern to create various designs.

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.

Front lighting system for vehicles that provides improved high and low beams without dark areas between them. The system uses two separate light sources for high and low beams. A transparent shutter with carved slits redirects and concentrates light from the high-beam source. This allows for the use of large high-beam sources while avoiding shadows. The transparent shutter also has surfaces to control output distribution. The shutter is placed in focal planes of primary and secondary optics for efficient beam shaping.

This is a vehicle headlight system with improved resolution and lower electronic complexity. The system uses two headlamps with light modules containing matrix arrangements of light pixels. Each module generates a light distribution by radiating light from individual pixels. This provides higher resolution without increasing the LED count. It also allows precise shaping of beam patterns. By splitting the beam generation between two lamps, the complexity and heat are reduced compared to one lamp.

A light-guiding component that can enable multi-function vehicle lights using a single light source. The component has two light incidence areas facing different directions that receive light from separate sources. The light is guided by internal reflections to a shared exit surface area. This reduces the light guide's thickness compared to collinear light entry and exit areas.

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.
