LIGHTING APPARATUS, LAMP, VEHICLE, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM

A lighting apparatus includes a step-up converter, at least one step-down converter, and a controller. The step-up converter is configured to step up a voltage of a direct-current power supply to obtain an output voltage having a first voltage value and output the output voltage. The at least one st...

Beschreibung
Zusammenfassung:	A lighting apparatus includes a step-up converter, at least one step-down converter, and a controller. The step-up converter is configured to step up a voltage of a direct-current power supply to obtain an output voltage having a first voltage value and output the output voltage. The at least one step-down converter is configured to step down the output voltage of the step-up converter to have a second voltage value to output a current having a current value according to the second voltage value to a light source. The controller is configured to acquire information about a specification of the light source, control the step-down converter such that the current value becomes a current value according to the specification, and control the step-up converter such that the first voltage value changes in accordance with the specification.
