Betty is a home portable lantern that resonates with the ancient Betty lamp contemporary. It allows people to use it as a portable illumination. The archetype is assembled by a diffuser and a base that has a handle in a race shape, the device could be sitting on a charging tray.

The interaction has two ways. Turn it on and off by pressing the diffuser in the normal stand or pressing the base once it stands in update side down status. The dimming feature could be achieved by rotating the diffuser.
