Commissioned for the Gao family hotels in Ordos, Inner Mongolia and Beijing, Ar. Margot Krasojević designs seismic lighting using electro-magnetic induction LEDs…

Ar. Margot Krasojević has been developing a dialogue between architectural form, geometry, sustainability and smart materials as an inherent part of the design process, dictating the terms of architectural design criteria rather than referring to sustainable technology as a polite afterthought.

She now designs the seismic LED light that consists of a 3d printed net, whose recycled polymer geometry is elastic, yet strong enough to stretch and reform, when subjected to tremors and shifting changes in its immediate environment.

.

This net is designed to give the illusion of intensifying the emitted light due to the dome shape, which channels the light around the surface of the semi-transparent geometry. When charged, the LED is a bright 60 Candela white light visible for 3 metres in a dark room. A main structural thread pipe is at the core of the LED and can be inserted into the ground for stability. It holds a series of magnets and a copper coil used to induce an electrical current.

.

The 3d printed net resonates and amplifies kinetic energy transforming it into electrical current, lighting the series of LED'S embedded within the geometry. All reverberations within the vicinity of the light induce a current by moving the magnets through the copper coil placed within the main structural thread pipe, using the principle of electromagnetic induction.

The net's spiral envelope is constructed from a flexible recycled polymer, whose geometry intensifies its displacement moving the magnets inside the supporting thread pipe to create a current, which can either be stored or dissipated immediately by lighting the LED.

To summarise, the main body of the light acts as a moveable piston intensified by the harmonic oscillating motion of the weighted 3d printed net as it stretches and expands. Currently, the light is being adapted so that the inner surface of the 3d printed net is coated with copper. This will strengthen the magnetic field causing to induce a higher and more constant electric current that lights the LED. The LED will light brighter whilst charging the battery as it is used.

Also in consideration, is the application of a piezoelectric zinc element to produce a current strong enough to light a 9V LED. Investigations in the field of semi-conductors contribute to affordable, sustainable lighting for the future, a quest for free energy.

Ar. Margot Krasojević, as always, continues to work on optimising renewable energy and the collaboration between program, typology, and architecture.
