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.
