To provide a light emitting unit used as a decoration for obtaining a beautiful sight by blinking pales of an artificial flower for a single-flower vase.
In this inclination sensing type light emitting device by which the artificial flower F for the single-flower vase can obtain elegant illumination effects by three color LED, the light emitting unit is formed so that a battery holding member 3 for housing a battery 2, an inclination sensor switch member 4, and a light emitting lamp 5 are provided in the upper part of a base board, a power supply circuit is switched on and off due to the inclination position change of the inclination sensor switch member 4, when the inclination sensor switch member 4 is in an upward position, the power supply circuit is switched on to make the light emitting lamp member 5 emit light, and when the inclination sensor switch member 4 is in a sided state, the power supply circuit is switched off to put out the light emitting lamp member 5.
