▎ 摘　　要

NOVELTY - The device has a graphite heating film formed on a glass surface of a lens through a control switch. The control switch controls a power supply part when the power supply part supplies power to the graphene heating film. The graphene heating film is arranged with the power supply part. USE - Graphene film based lens heating device. ADVANTAGE - The device has better heat generation effect, and utilizes the control switch for controlling the power supply part so as to control operation of the heating film, arranges the graphene heating film on an inner side of the lens glass and outer side of the lens glass so as to coat a surface of the glass in an easy manner and satisfies requirement of defrosting and defogging in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a graphene film based lens heating device. '(Drawing includes non-English language text)'
