Abstract
A light emitting device is switchable in a first state and a second state, and includes light emitting elements and an optical element. A first portion of the light emitting elements is configured to emit first lights. A second portion of the light emitting elements is configured to emit second lights. The optical element is configured to guide the first lights for switching the light emitting device in the first state. In the first state, the light emitting device has output lights, a first intensity of the output lights is measured at a viewing angle of 0°, a second intensity of the output lights is measured at a viewing angle of θand an azimuth angle of Φ, and a ratio of the second intensity to the first intensity is less than or equal to 0.1, wherein θranges from 30° to 60°, and Φis 14° or 166°.
