Yu Ito, Yoshimi Kemmotsu, and Bin Sugawara of SOL style design Lei Aroma diffuser, an ultimately sustainable aroma diffuser, creating electricity from the heat of a candle instead of a power source.
Utilizing the thermoelectric effect, Lei generates electricity through the temperature difference in the metal part.
Lei Non-Electric Aroma Diffuser recently won a 2021 Good Design Award from The Chicago Athenaeum: Museum of Architecture and Design and The European Centre for Architecture Art Design and Urban Studies.
The generated electricity creates a gentle breeze that allows the volatilized aroma to permeate space.
It is a self-sufficient, sustainable product patented for its innovative invention which redefines existing home appliances.
Every aspect is crucial and designed to make an effective pathway for fragrance and breeze, such as the glass cylindrical dome which raises the heat of the flame, the optimal gap above the dome, the single blade fan to introduce oxygen, and oval shape for heat dissipation.
The manufacturer only used recyclable materials including packages (metal, glass, aluminum, paper).
Being a cordless product, Lei can be transported and used anywhere. The oil is dropped straight into a tray, making it easy to replenish or clean.
The product is also designed to allow users to enjoy the aroma with minimal consumption.
While other products tend to overheat oils, Lei uses gentle heat which preserves aroma quality.
It guarantees safe usage with the sturdy steel platform which prevents tipping, while the glass dome protects users from the candle’s flame.
The concept and execution of Lei reinforce the designers’ ethics of being greatly aware of the products’ environmental lifespan, through both manufacturing and up-cycling, as well as raising questions about the industry’s sustainability issues.
It also stands as an important hint for future “home appliances” which function with electricity without using a power source.
