Kensaku Oshiro (designer) Light is not a substance, making its presentation a challenge for designers

Kensaku Oshiro was born in Okinawa prefecture in 1977. After graduating from the Scuola Politecnica di Design Milano in 1999 he worked for Lissoni Associati and Barber Osgerby. In 2015, he established his own studio, Kensaku Oshiro, in Milan. He has worked with Italian furniture makers including Boffi, De Padova, Kristalia, Ligne Roset, Poltrona Frau and Zanotta, as well as releasing furniture with Arflex Japan.

When the Milan-based designer Kensaku Oshiro visited Nitto’s “Search for Light” exhibition at Milan Design Week, what were his impressions of RAYCREA? Oshiro studied design at the Polytechnic University of Milan's graduate school, before working as a designer for leading Italian designer Piero Lissoni and British design unit Barber Osgerby. Oshiro went on to establish his own studio in 2015 and currently works with some of Italy's leading furniture makers. He is also working on projects in Japan and a growing number of locations.

"To be honest, I couldn't understand how it worked at first. I saw the expressions produced by RAYCREA, but couldn't get my head around it… I thought that the film itself was connected to a power supply and emitted light on its own, but upon hearing the explanation, I realized that the film actually changes the direction of light. Once I understood that, I felt that the idea and the technology have great potential. The film can provide illumination without showing the light source, and it can also be transparent. These features allow it to produce some interesting effects.”

Poltrona Frau's new Sparkler outdoor lighting was released at Milan Design Week in 2021. The lighting comes in three sizes: two floor lamps and a small-scale table lamp. They are made from a lightweight powder-coated aluminum frame upon which polypropylene rope is handwoven, and can be placed on the floor or hung from the ceiling. The LED light comes with an 8W lithium battery that can be recharged via USB connection. The light and the shadows it creates have been carefully designed.

When asked what kind of products he’d like to design with RAYCREA, Oshiro laughs. "I need to consider it a bit more; it's still hard to imagine," he replies. "The fact that it can be used on a large surface makes it well suited to architecture." Oshiro has been working on a marine education facility on Yoron Island in 2021. Approaching architecture from a product designer's perspective, he's been devising ideas such as a water-based cooling system.

“RAYCREA is a new material, which means we need to explore the lighting effects and their possibilities. It's a one-of-a-kind material with innovative expressions not seen in other materials. Combining it with materials such as glass and mirrors will be sure to produce some interesting effects.”

In 2021, Oshiro also launched Sparkler, an outdoor lantern produced by Italian furniture maker Poltrona Frau. Powered by an LED light, the portable lantern comes in three sizes.

“Light is not a substance. That’s why designers need to consider how to show its presence. At the studio where I used to work, I was involved in a wide range of projects, such as developing lighting objects and architectural lighting with major manufacturers. We had the experience of shifting from incandescent globes to LED light sources. It was difficult to get used to this change, but it's now possible to create expressions aligned with their characteristics. Overcoming the sense of discomfort that comes with new technology and taking advantage of its features may be the key to designing with RAYCREA. I feel that changing the angle of the light creates a lot of possibilities. Additionally, the film has a high degree of flexibility. The technology is there, so you can fuse it together with design. By doing so, new lighting expressions can be created.”
