Bonfire is one of the most reliable as well as conventional sources to keep warm during the chilly season. However, bonfires do have an adverse impact on the environment and can also be dangerous because of its flying sparks. Designer Kang Kyung Lee has now come up with a LED lamp that will not just keep the dangers at bay but also help in sustaining the environment. Known as ‘Bonfire,’ the LED lamp resembles an assortment of lighted sticks. All, the users need to do is twist the lamp around repeatedly in their hands to turn them on. Though, there is no info on the power source of the conceptual lamp, but it seems to be running on the kinetic energy generated from the hands of the users or an induction charging base. Users may arrange the Bonfire lamp in two different ways, they can set it up as a pillar of three light poles or they can twist it into a more conventional shape. But I’m not too sure if the LED lights will be good enough to keep you warm in the freezing winters.
