US 12,377,773 B2 · Lighting control apparatus

Abstract

A lighting control apparatus is configured to be applied to a vehicle lamp. The lighting control apparatus includes a first switching converter, a substrate on which the first switching converter is provided, and a first cover. The first switching converter includes a switching element, a coil, and a first output capacitor and is configured to generate a first drive voltage corresponding to a first light source of the vehicle lamp based on a power source voltage. The first cover is formed of a conductive material and covers at least a part of components of the first switching converter in one surface of the substrate. The substrate includes a first conduction part and a second conduction part which are in conductive contact with the first cover. The first switching converter is provided between the first conduction part and the second conduction part. The first output capacitor is provided in a vicinity of one part of the first conduction part and the second conduction part.
