Abstract
A vehicle lamp using a fluid lens and a control method of the vehicle lamp are provided. The vehicle lamp notifies the driving status of a vehicle to the drivers of following vehicles via a tail lamp. In particular the vehicle lamp includes a light source and a fluid lens that changes a curvature shape of the fluid lens based on an input current and generates a light emission image that corresponds to a driving status of a vehicle to the exterior of the vehicle lamp. Additionally, the input current varies based on the driving status of the vehicle.
