Description

Protective enclosure for outdoor projectors

The present invention relates to an outdoor projector enclosure.

A projector is a type of optical device that projects an image enlarged through a lens unit onto a screen.

It is widely used in educational institutions, businesses, and homes because of the advantage of being able to display a large screen regardless of indoor or outdoor space where the screen can be installed.
