Abstract
A manufacturing method of a snow goggles device includes: providing an optical substrate layer on a snow goggles frame; providing the optical substrate layer with a first surface and a second surface, and forming at least one transparent conductive film on the first surface, the second surface or therebetween; electrically connecting the at least one transparent conductive film with a power supply unit and a switch unit, with providing the power supply unit and the switch unit on the snow goggles frame; and operating the power supply unit to supply a current to the at least one transparent conductive film via the switch unit to thereby heat the optical substrate layer.
Claims20
A snow goggles device comprising:
- an optical substrate layer provided with a first surface and a second surface;
- a snow goggles frame provided with a predetermined area, with providing the optical substrate layer on the predetermined area of the snow goggles frame;
- at least one transparent conductive film provided on the first surface, the second surface or therebetween;
- at least one power supply unit electrically connecting with the at least one transparent conductive film, with providing the power supply unit on the snow goggles frame;
- and
- a switch unit electrically connecting between the at least one transparent conductive film and the power supply unit, with providing the switch unit on the snow goggles frame;
- wherein the power supply unit is operated to supply a current to the at least one transparent conductive film via the switch unit to thereby heat the optical substrate layer for preventing the optical substrate layer turning into a frozen state.
