Artistic Styling in Automotive Lighting

A lens arrangement for vehicle headlights that allows precise control of light patterns and projects images onto the environment. The lens arrangement includes multiple lenses arranged in a specific order. This allows the light from an LED matrix in the headlight to be focused and projected in a controlled pattern. The lens arrangement can be used in adaptive headlights to dynamically adjust the illumination pattern based on conditions like speed and surrounding obstacles.

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.

Vehicle lamp that improves visibility and miniaturizes the reverse guide lamp while ensuring visibility. The lamp has a housing with two optical modules: one angled downward to illuminate the road behind the vehicle and one forward facing. The angled module protrudes upward from the housing to increase visibility.

A vehicle headlight system that performs an animated sequence using pivoting lights to imitate human eyes, giving the impression that the vehicle is "waking up" and "looking" at the person approaching. The headlights have pivotable modules that can move up and down, as well as left and right. When an authorized user approaches the vehicle, the headlights pivot up from a downward position to a horizontal driving position. Then, depending on the user's direction, the headlights pivot towards them, pausing briefly to "look" before returning to the forward driving position.

A red phosphor for LED lighting that has high reflectance in a specific wavelength range from the emission peak wavelength to 800 nm and that includes a crystal phase with a specific composition, such as SrLi(Al, Ga)3N4:Eu. The phosphor has a red emission peak with favorable characteristics like narrow bandwidth and high intensity, as well as improved efficiency, color rendering, and conversion compared to existing red phosphors.

A vehicle lighting apparatus that can emit different colors from a single red light source while still meeting color regulations. The lighting apparatus has: a red LED, a red phosphor layer, and a color filter. The red LED excites the phosphor to emit red light. The color filter selectively transmits some red light while blocking other wavelengths. This allows only certain red light to pass through and appear white or orange. The color filter properties are tuned to meet regulations.

Vehicle interior dual-lamp head contrasting atmosphere lamp assembly that provides improved contrast and luxury compared to traditional same-color interior lights. The assembly has two separate LED modules mounted on opposite ends of a light guide strip in the instrument panel. Each module contains LED groups that emit monochromatic light. This allows independent control and contrasting colors between the modules to create vivid and distinctive lighting effects in the instrument panel area.

Vehicle lighting system that improves exterior design by extending light from the main illumination area of the vehicle body to adjacent areas like the bumper or grill. The lighting system has a housing with a main lighting area and an extended lighting area. A light source irradiates light into the main lighting area. A movable light guide extends between the main and extended areas. By selectively partitioning the light guide, light can be emitted only in the main area or both main and extended areas. A driving mechanism moves the guide block to selectively emit light in just the main area or both main and extended areas. This allows lighting to be focused just on the main area or extended to the adjacent areas.

Dynamic LED lamp system for vehicles that generates animated lighting effects by shifting LED colors based on temperature changes. The lamp system uses temperature control devices like PTCs, Peltiers, fans, and heat sinks to change the LED temperature. This causes the LEDs to shift colors as they warm up or cool down. The lamp cells are grouped and arranged in patterns like full region, zigzag, outline, partial, sequential, individual rotation, Peltier current control, and Peltier current combination. The lamps can externally emit the shifted colors to create dynamic lighting effects for vehicle design and mood.

Vehicle lighting device that can change the color of the light output by varying the transmittance of an intermediate part between the light source and reflector. The device has a light source, reflector, and variable transmission part. The reflector reflects the light with a different color than the source to change the color. The variable transmission part is between the source and reflector and can adjust the transmittance. When low, the light from the source goes directly out. When high, the light goes through the variable part to the reflector where it reflects and changes color. This allows changing the color of the reflected light without adding color elements.

Vehicle lighting system with customizable color options using a stacked light guide structure. The lighting system has two light source modules, each with a light guide member. One light guide guides light from its source, and the other guides light from the first source as well as its own. This stacked configuration allows interference between the two light sources' emitted light to create a variety of colors.

An in-vehicle lighting device that provides a high decorative effect inside a vehicle. The lighting device has a lighting unit with a light emitting portion and a cover. The cover is transparent when the lighting unit is off or emitting a first color, but becomes opaque when the lighting unit emits a second color different from the first. This allows the light emitting portion to be hidden when emitting the first color, but revealed when emitting the second color, providing a visual contrast and decorative effect.

A vehicle lamp with 3D lighting effects using multiple light sources and light guiding structures. The lamp has adjacent light source modules emitting visible light. Each module has an excitation light-emitting layer for a specific wavelength. A light guiding structure adjacent to the module guides the excitation light emitted from that module to the adjacent module's light-emitting layer. This allows implementing a 3D lighting effect with depth and shape variation by using multiple light sources and guiding the excitation light between them.

A rear position lamp with a unique light distribution pattern that provides a 3D-looking light output. The lamp has an outer lens system that consists of a colored transparent mirror followed by a 3D light reflector. The colored transparent mirror refracts the light and the 3D reflector further shapes and reflects it. This creates a layered, multi-dimensional light pattern.

A vehicle rear lamp module that can produce two distinct light patterns using a single LED. The module has a primary pattern film with an optic to create a first light pattern when the LED is lit. An optical resin and secondary pattern film with a different optic are added to produce a second light pattern. This allows two distinct patterns using just one LED. The films are sandwiched between the PCB and reflective film to increase light efficiency. When the LED is off, the reflective film provides a hidden effect. The optics project opposite directions and angles less than 90° to overlap or cross patterns.

Light-transmissive vehicle component with enhanced aesthetics and nighttime warning capability. The component has a substrate with embedded light-emitting bodies. A translucent decorative cover is attached to one side of the substrate. The cover has a shape and a colored layer on its surface. This allows the embedded lights to shine through the cover when illuminated, providing illuminated branding during the day and night. The colored layer on the cover adds visual interest during the day when light is transmitted through it. The shape of the cover can be a polygon to further enhance visual appeal.

A vehicle illumination method that provides flexible, customizable, and concealable lighting for vehicles that can be remotely controlled and integrated into vehicle styling. The method involves using LEDs, fiber optics, and printed circuit boards (PCBs) programmed to change colors. The LEDs and fiber optics are contained within a photometric lens for illumination control. The PCBs are housed in an outer plastic molding with one surface coated in translucent physical vapor deposition (PVD) and the other surface masked to create desired patterns and shapes. This allows the illuminated areas to appear as concealed ornaments when off and reveal the lighting patterns when activated. The molding is attached to a back molding and roof rail. The LEDs and fiber optics can be remotely controlled to change colors. This allows customizable, concealed lighting that can be integrated into vehicle styling
