OBELUS | LED Desk Lamp Concept by Igor Lobanov from russia

designer's own words:

OBELUS Desk Lamp.

Base idea is addition of two existing technologies into one solution: LED Edge Lit + Smart Glass.
Edge Lit uses special light guide panel which has small dots inside to diffuse light comes from LEDs positioned along panel's edges.
Smart Glass technology provides an ability to change thin film's transparancy due to changing of electric current properies.
The combining of these features together allows to manipulate with light direction and its intensity in a SUPER SLIM form factor without any mechanical elements.

This principle allows to adjust and redistribute basic luminous flux to provide comfort atmosphere at the workplace and can be extrapolated on different luminaire's types, such as floor task lamp or pendants.

This main feature became possible due to multilayer light guide panel.
The typical light guide panel for edge lit is additionally covered with smart glass film on both sides (its top and bottom).
Smart film is able to change its transparency / matte properties depending on current flow properties, so it provides an ability to control the light goes through it and, in addition with light guide panel, to manipulate with light distribution in up and down directions.

OBELUS has 4 basic states:
- light is switched off;
- uplight;
- downlight;
- uplight + downlight.

There is a stripe of control sensor on the stand part which includes two dimming zones.
One zone controls uplight and another one is for downlight.

It is possible to use both directions at one time and to have smooth control between
limit values by sliding.
