Beschreibung
Zusammenfassung:	A light emitting device includes a light emitting unit, a reflective plate, and a diffusion plate. The reflective plate is disposed on the optical path of the light emitting unit. The diffusion plate is pivoted to the reflective plate. When the reflective plate is opened relative to the diffusion plate in an angle, the light emitting unit emits an incident light to the reflective plate, and the reflective plate reflects the incident light to the diffusion plate and generates a reflective light, and the reflective light passes through the diffusion plate and is output as a planar light.
