Patent number: 10215951Abstract: The present invention relates to a camera module, and the present invention comprises: a lens unit; a lens barrel for fixing the lens unit; a substrate unit, which has an image sensor mounted thereon, for converting light incident through the lens unit into an electric signal; and a housing accommodating the substrate unit in an inner space thereof and of which one side is coupled to the lens barrel, and the present invention can comprise: a transmission coil accommodated inside the housing so as to form an electric field, and a conductive heating element arranged on an outer surface of the lens unit or on an outer circumferential surface of the lens barrel, and in which an induced current is generated by the electric field formed by the transmission coil. Since the present invention heats a lens by wirelessly supplying power to a heating element through simple configurations such as a transmission coil and the heating element, large changes are unnecessary in the volume and the structure of a camera module.Type: GrantFiled: July 8, 2016Date of Patent: February 26, 2019Assignee: LG INNOTEK CO., LTD.Inventors: Seung Ryong Park, Jae Hun Sung, Jung Hoo Seo, Se Kyu Lee, Soo Min Jeong
