Flashlight device for generating light flash over extended light surface, has flashlight source, where light surface is realized by light guide plate, and coupling device is provided for coupling light over coupling surface

摘要

The flashlight device has a flashlight source (5), where a light surface (3) is realized by a light guide plate (2). A coupling device (6) is provided for coupling the light over a coupling surface (4) of the light guide plate. The light guide plate has a structure formed for homogeneous coupling of the light over the light surface. the structure has a structured surface of the light guide plate or scattering center within the light guide plate or a pressure structure (14).
