An LED lighting device comprise a lamp cap; a case, connected to the lamp along in a first direction and having a cavity; a power supply disposed in the case; connected to the lamp along in a first direction and having a cavity; and a light emission unit. The light emission unit and the heat exchange unit are connected to form a thermal conduction path, the light emission unit and the power supply are electrically connected. When the first direction is substantially parallel to the horizontal plane, the light emitting unit of the LED lighting device provides downward light emission. The fixing unit comprises a first member, and a second member, the first member and the second member are in a form of slide connection.
