Publication number: 20210116674Abstract: A lens moving apparatus includes a housing, a bobbin disposed in the housing, a first coil disposed on the bobbin, a magnet configured to move the bobbin in a first direction parallel to an optical axis by an electromagnetic interaction with the first coil, an elastic member coupled to the bobbin, and a second coil disposed on the housing. A first portion of the second coil is coupled to the housing. The second coil generates an induction voltage resulting from an inductive interaction with the first coil when the bobbin moves in the first direction.Type: ApplicationFiled: December 28, 2020Publication date: April 22, 2021Applicant: LG INNOTEK CO., LTD.Inventors: Jung Cheol KIM, Kap Jin LEE
