Abstract
A heating device for a camera module comprises: a resistance heating film formed on a lens through which external light is introduced for generating heat by electric current; a power applying member for supplying the electric current to the resistance heating film; and a connecting member for electrically connecting the resistance heating film and the power applying member in close contact with each other.
Claims20
A heating device for a camera module, comprising;
- a resistance heating film disposed on a first lens;
- a connecting member disposed on the resistance heating film;
- and
- a power applying member disposed on the connecting member,
- wherein the connecting member is disposed on a first portion of the resistance heating film, the first portion of the resistance heating film being disposed on a peripheral part of the first lens,
- wherein the connecting member comprises a sheet member disposed at a bottom surface facing an upper surface of the power applying member facing the resistance heating film and having an elasticity closely connecting the power applying member to the resistance heating film,
- wherein the power applying member comprises a terminal part in physical contact with the connecting member,
- wherein the power applying member comprises a first power applying part disposed on the connecting member and comprising an upper surface facing the connecting member, a second power applying part spaced apart from the first power applying part in an optical axis direction and comprising an upper surface that is parallel to the upper surface of the first power applying part, and a connecting part connecting the first power applying part and the second power applying part,
- wherein the upper surface of the first power applying part of the power applying member and the upper surface of the second power applying part of the power applying member are both perpendicular to the optical axis direction, and
- wherein the connecting part of the power applying member extends away from the first power applying part in the optical axis direction.
