Light emitting device and vehicle

Abstract

The application provides a light emitting device and a vehicle. The light emitting device comprises a cover, a light source assembly and a piezoelectric component. The cover is capable of transmitting light. The light source assembly is arranged on one side of a light entrance surface of the cover and is used for generating light. The piezoelectric component is arranged on one side of the light entrance surface of the cover. In the case that the cover is deformed, the piezoelectric component generates an electric signal under the action of the deformation of the cover. The electric signal is used for controlling the working state of the light source assembly. The light emitting device can improve the reliability of the light emitting device and reduce the volume of the light emitting device.
