Throughout the 1950s, Mouille designed a series of angular, insect-like wall-mounted and standing lamps and smaller, more curved wall sconces. His works are characterized by their sculptural aesthetic by eschewing the complexity of Italian models, which were becoming popular in the market during the 1950s.
Mouille’s contributions to the field of lighting design extended beyond his works. He established the Société de Création de Modèles (SCM) in 1961 as a means of fostering young and emerging lighting designers. Mouille continued to work and teach for the rest of his life, exhibiting his lighting and jewelry designs at various exhibitions.
Mouille’s contributions to the field of lighting design were recognized through various awards and honors, including a medal from the City of Paris and the Charles Plumet prize. He also undertook institutional lighting design projects, including at the University in Antony, schools in Strasbourg and Marseilles, and the Bizerte Cathedral. Mouille’s later works, such as his “Colonnes” collection, which combined incandescence and fluorescence, debuted at the 1962 Salon for interior design and cemented his reputation as an innovative and influential designer in the field of lighting design.
