The name means the Shining One or Lightbearer. He is also known as the Son of the Morning. Lucifer was a spirit son of Heavenly Father and led the rebellion in the premortal life. The name Lucifer appears only once in the Bible (Isa. 14: 12). Latter-day revelation gives more detail on Lucifer's fall (D&C 76: 25-29).

Lucifer fell in the premortal existence, Isa. 14: 12 (Luke 10: 18; 2 Ne. 24: 12). After his fall he became Satan and the devil, D&C 76: 25-29 (Moses 4: 1-4).
