How does the anti-fog LED mirror work?

When people take a shower, the shower water temperature is about 40°C, the surface of the bathroom mirror is much lower than the room temperature, that’s the reason why fog is formed on the mirror surface. The anti-fog LED mirrors heat up the mirror to prevent the mirror surface from condensation of steam in bathroom effectively. The anti-fog LED mirrors can be not only used for decoration, but also meet the needs of makeup after shower.
