Abstract: A light emitting device controlled by placement angle thereof includes a housing space disposed inside a shell element, wherein a light emitting element, a power supply element, and a conductive element are disposed in the housing space. The conductive element has a passage having a conductor therein. By a tilt of the shell element, a placement angle thereof is changed, whereby the conductor moves inside the passage between a conducting position and a disconnecting position. The wire set between the light emitting element and the power supply element is conductive when the conductor is at the conducting position, and is not conductive when the conductor is at the disconnecting position. Thus, the light emitting element is able to be controlled by changing the placement angle of an object to which the light emitting device attached, thereby achieving the convenience for usage.
