Light-emitting device capable of achieving clear sky effect

The invention relates to the technical field of illuminating lamps, and particularly discloses a light-emitting device capable of achieving a clear sky effect. The light-emitting device capable of achieving the clear sky effect comprises a lamp cavity, a lamp panel base, wherein the lamp panel base is fixed to the bottom of the lamp cavity, and an LED lamp strip is arranged on the upward face of the lamp panel base. an optical plate, wherein the optical plate and the lamp panel base are arranged in parallel, so that the LED lamp strip is positioned between the lamp panel base and the optical plate; and a clear sky plate, wherein the clear sky plate is arranged at the top of the lamp cavity; and the included angle between the optical plate and the bottom face of the lamp cavity and the included angle between the lamp plate base and the bottom face of the lamp cavity are 30-60 degrees. The light-emitting device for achieving the clear sky effect can well simulate the clear sky effect, so that sky blue lighting
