The invention discloses an energy-saving LED bulb lamp. The energy-saving LED bulb lamp comprises a lamp cap, a radiator, a lampshade, an arc-surface mounting plate, LED packages, LED lamp beads, a transformer rectifier, a starter, a lamp cap head, a threaded connector and the like; the radiator is arranged on the lamp cap through screws on the side surface of the lamp cap; the lampshade is connected to the radiator through threads; the lamp cap head and the threaded connector are arranged on the lamp cap; the top end of the lamp cap head and the threaded connector are made of metal materials;a plurality of circuit elements including the transformer rectifier, an internally-installed electric lead and the starter are arranged inside the radiator; and the input end of the transformer rectifier is connected to the top end of the lamp cap head and the inner side of the threaded connector through two leads. The energy-saving LED bulb lamp has the advantages that a large number of LED lampbeads are arranged on the arc-surface LED lamp bead mounting plate, so that on the premise of reducing the through current of a single LED lamp bead, the brightness of the energy-saving lamp can be improved to the maximum degree; and in addition, a homogeneous fluorescent coating is sprayed on the inner side of the lampshade, and the yield of the color region of the energy-saving lamp can be improved.
