Enhanced Brightness in Automotive Headlights

Lighting device for cars with uniform lighting effect without glare or dark spots. It uses phosphor-coated reflective bowls that slide over an invisible LED source. The bowls have phosphor layers with different colors. When a bowl slides directly under the LED, the phosphor lights up for uniform illumination. A micro servo moves the bowls. A sensor positions them. This allows adjusting the lit bowl color. The invisible LED prevents direct glare. The bowls reflect light. Patterns on the bowls and lens further scatter the illumination.

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.

LED car headlight design that eliminates the need for professional dimming and provides better coverage without blind spots. The headlight uses a multi-faceted LED array that emits light from all sides, eliminating shadows. The LED module is mounted on a heat sink with a snap ring to secure it in place. The snap ring snaps onto matching features on the headlight housing. This allows self-contained installation without needing to dim the light during assembly. The snap ring also centers the LED module for alignment. The LED array has a heat conducting body on the bottom, and the snap ring prevents it from moving. The LED module connects to the headlight's power and cooling system through the snap ring.

LED automotive exterior lamp with customizable color output and improved light quality. The lamp uses a specialized LED tube core with a phosphor conversion layer to emit secondary light with specific color characteristics. The phosphor converts the primary LED light into secondary light that can have customized color points like yellow or warm white. The phosphor material used in the conversion layer is a ceramic garnet phosphor with specific compositions, pore sizes, and grain sizes. This allows fine control over the secondary light spectrum. The customizable color output of the lamp is achieved by using this specialized LED tube core with the optimized phosphor material.

LED headlight for vehicles that provides better low beam lighting with reduced glare to other drivers and pedestrians. The headlight has a ceramic substrate with multiple LED chips attached, some covered by a phosphor diaphragm. A light blocking member is flush with the uncovered LED chips. This configuration creates a low beam pattern that illuminates the ground well without dazzling opposing drivers. The LED chips are driven by separate current loops to control on/off states.

High-intensity LED automotive lamp with improved light output and beam pattern compared to conventional LED headlights. The lamp uses a unique design where two integrated reflectors emit light from corresponding SMD LEDs. The reflectors are aligned and fixed above the circuit board with the LEDs. This allows both reflectors to reflect light in the same direction, increasing intensity compared to separate reflectors and LEDs. It also avoids the issues of low intensity and narrow beams from single high-power LEDs. The central control sends a signal to drive the LEDs, which emit through the reflectors to achieve bright headlights.

Light-emitting device with adjustable color temperature and high color rendering index in low color temperature range without compromising luminous flux. The device has separate red, green, blue, and white LEDs with a circuit to control their fluxes. In low color temperature white, the red LED weight is reduced compared to other colors. This reduces phosphor usage, increasing flux. The red and green fluxes are adjusted by the circuit to compensate. This allows higher flux, better color rendering white light at lower color temps compared to reducing overall flux.

LED lamp for automotive headlights that provides high initial brightness and improves safety by gradually reducing power as the lamp heats up. The lamp has an LED substrate on the lamp holder, a heat sink below, and a power lead on the heat sink. An LED driver is connected to the power lead. The driver initially provides high power to the LEDs until they stabilize, then reduces power as the heat sink temperature rises. This gives high initial brightness for safety and reminding, then reduces power as the lamp warms.

A light-emitting device for vehicles like cars with improved appearance using multi-color LED units. Each multi-color LED unit contains multiple monochromatic LEDs and a microcontroller integrated in the same housing. The microcontroller adjusts the brightness and chromaticity of each LED based on the local temperature to compensate for variations. This prevents color shifts and non-uniformity across units when powered. The microcontrollers communicate internally to coordinate brightness and color adjustments. The main controller sends commands via an internal bus. This allows each unit to adapt and maintain consistent appearance despite temperature differences.
