Beschreibung
Zusammenfassung:	The utility model discloses a heart-shaped light emitting diode (LED) bulb lamp which comprises a lamp holder connected with a power source, a driver, a radiator, an LED light source component and an outer cover and further comprises a pointed portion which is formed at the top of the outer cover and recessed downwards towards the inner side of the outer cover. The pointed portion is a slewing body formed by an arc wire. Due to arrangement of the pointed portion, an inner wall of the pointed portion reflects a part of light rays facing the top. Due to the reflection of the light rays, on one hand, the shortage that the top of the outer cover is over strong in light can be avoided, and on the other hand, the reflected light rays formed by the pointed portion further enable a light-emitting angle of the whole bulb lamp to be enlarged, and the effect of large angle light emission is achieved. In addition, the structure can further beautify the LED bulb lamp.
