Japanese studio Kairi Eguchi Design, have recently launched their Trans-Lamp Collection that includes four different styles of lamps. An experimental series that is designed based on the idea of applying theoretical mathematic calculation on standard products to form new products. When the products get place in the same space, they naturally link to one and other, and add a graceful rhythm to the space. A luminaire lights the room/atmosphere with a gentle light by covering the light source with a shade and controlling the glare. By shifting the heights in specific levels while preserving the volume of the frustum of cone, we present a new series of lighting equipment that allows your body to feel the same voluminous whilst changing its style depending on the usage.
