Application of smart lights in vehicles
In recent years, with the development of artificial intelligence technology and the upgrading of automobile consumption, automobile lighting is also gradually moving towards intelligence. As a visual and safety component, headlights are expected to become the core carrier of the vehicle data flow output end, realizing the functional upgrade from “functional” to “intelligent”.
The requirements of smart car lights for capacitors and the role of capacitors
Due to the upgrade of smart car lights, the number of LEDs used inside has also increased, making the working current of the car lights larger. The increase in current is accompanied by greater ripple disturbance and voltage fluctuation, which greatly shortens the light effect and life of LED car lights. At this time, the capacitor that plays the role of energy storage and filtering is crucial.
YMIN liquid SMD aluminum electrolytic capacitors and solid-liquid hybrid aluminum electrolytic capacitors both have the characteristics of low ESR, which can filter stray noise and interference in the circuit, ensure that the brightness of the car lights is constant and will not be affected by circuit interference. In addition, low ESR can ensure that the capacitor maintains a low ripple temperature rise when a large ripple current passes through, meet the heat dissipation requirements of the car lights, and extend the life of the car lights.
