Abstract
A light emitting bulb is provided. The light emitting bulb comprises a light source and a cover. The light source is for emitting light. The cover defines an inner space and the light source is disposed inside the cover and heat conductively connected to the cover. The cover is made of heat conductive material and capable of reflecting the light emitted by the light source into the inner space. Therein, a plurality of apertures is formed on the cover to let the light emitted by the light source disposed within the cover emit out from the apertures.
