摘要： A discharge lamp lighting circuit 100 supplies power to a discharge lamp 226 used as a light source of a vehicle lighting device capable of switching between a first state and a second state by light distribution change means. A light distribution pattern of the second state is different from a light distribution pattern of the first state. The power supplied to the discharge lamp 226 is changed at a timing of switching from the first state to the second state.

摘要： A lighting control device for a vehicle lighting device is arranged so that loads applied to switching regulators are about equal when driving multiple semiconductor light sources (e.g., LEDs) as multifunctional lamps through the switching regulators. The LEDs are divided into two groups. The LEDs belonging to the first group are driven to be turned ON through a first switching regulator and the LEDs belonging to the second group are driven to be turned ON through a second switching regulator. Maximum values of power to be supplied to the LEDs are set to be about equal to each other, and loads to be applied to the switching regulators are about equal to each other.
