An LED bulb lamp, comprising a standard bulb holder (1), a lamp body, a bulb (4) and an LED lamp set. The LED lamp set is disposed inside the lamp body. The bulb (4) is disposed at the front end of the lamp body and covers the LED lamp set. The LED lamp set comprises an aluminum substrate (5), several LED lamps (6) disposed on the aluminum substrate (5) and a driving power source (7). The lamp body comprises an upper body (2) connected to the standard bulb holder (1) and a heat dissipation cover (3) connected between the bulb (4) and the upper body (2). Several heat dissipation air channels (304) are arranged circumferentially and evenly on the heat dissipation cover (3). By adopting the heat dissipation air channel (304) on the heat dissipation cover (3), the heat from the LED lamp (6) is dissipated through the heat dissipation cover (3) and becomes rapidly dissipated through the flowing of air inside the heat dissipation air channels (304), thereby effectively solving the heat dissipation problem for an LED bulb lamp and increasing the reliability of an LED lamp. |
