The present invention relates to a magnifier provided with an LED, and more particularly, to a magnifier provided with an LED lighting means is provided to observe the object to be observed at night.

In general, a magnifying glass is a mechanism for viewing an enlarged shape when viewing an object to be observed, and is useful when observing a small object.

This magnifier uses the principle that the image of the object becomes larger when the image of the object reaches the human eye as the light passing through the convex lens is refracted inward.

Therefore, the magnifier is generally used as an observation tool for observing a minute object or an auxiliary device for various tasks, and is generally used for glasses for the visually impaired or the elderly. On the other hand, depending on the purpose of the complex configuration that is installed as an accessory of the optical equipment, while the configuration can be classified into a variety of forms, such as a portable magnifier is simple and easy to carry.
