By re-focusing on the elements of light, air and scenery that create the ambient environment, FOCUS continually recomposes. A number of thin, lightweight, flat lenses that maintain a mobile-like balance condenses and diffuses the natural light from the window and the ambient light in the room while surrendering itself to the air currents. After dark or when ambient light is weak, lighting devices embedded around the edges of the lenses illuminate the framed scenery, and affordance effects generated by light direct viewers' attention towards another scenery beyond the lenses. 

The aspects of FOCUS are created in response to their surroundings, in the same way that architecture is designed relative to its environment. And while the function and stability of electricity is important in lighting, FOCUS gives people scenery as an art object with the concept of natural light and air flow. This lighting is not limited to the fields of architecture, design and art, continually creating unique light and sceneries in space.

By using PMMA and aluminium, which are renewable materials, we are considering a sustainable recycling-oriented society. It is also important that these are not special materials that require energy costs and that they can be stably supplied. Since the weight of the product has a great impact not only on safety but also on environmental energy and transportation energy, consideration is given to keeping it light. The lenses are made from a specially processed 1mm-thick PMMA plate, which makes them extremely lightweight and safe. 

The electrical cord that forms the mobile is 2mm thick, which makes it light and at the same time give floating lenses sensations. The frames of the lighting and the bars of the mobile are made of aluminium, realizing the ease of molding and weight reduction. Variations of the mobile are 3 ~ 5 lens type with φ364mm and φ284mm lens combination, which can adjust the length of the upper electric cord up to 3m.

Originally, the value of lighting products is evaluated when they are lit, but FOCUS respects natural light while providing lighting design. Taking advantage of the charm of both artificial and natural light, it gives us the opportunity to rethink how we interact with people, environment and energy.
