Abstract
An LED lamp bulb, comprising: an LED lamp substrate (5) having at least one LED light source (51) mounted thereon; and an electrical isolation assembly (6a) disposed on the LED lamp substrate (5), wherein, the electrical isolation assembly (6a) electrically isolates the LED lamp substrate's charged part from outside of the LED lamp substrate (5). The LED lamp bulb can protect user from contacting the charged part inside the lamp housing (7) when the LED lamp bulb is broken and thereby avoid electric shock accidents. In addition, the directions of the light emitted by the LED light sources (51) can be changed to achieve different kinds of lighting effects.
