Abstract
A light emitting bulb, a luminary and an illumination device are provided. The light emitting bulb includes a main body and a bulb base. The main body has a plurality of the light emitting units. The bulb base has a plurality of flexible pieces. The flexible pieces are connected to the light emitting units respectively to form a plurality of electrical transmission paths. The luminary further has a lamp holder for holding the light emitting bulb. A control unit in the illumination device is connected to the light emitting bulb through the lamp holder for selectively providing a supply of a power to the light emitting units to control brightness of light emitting units, respectively. The light emitting bulb may facilitate color changing and brightness control without having a control circuit disposed within the light emitting bulb and is associated with a longer lifetime and a lower manufacturing cost.
