Acriche is the world’s first semiconductor light source that operates directly from AC power without a converter. This makes it suitable for many residential and commercial lighting applications where the main source of available power is AC. A design with Acriche product minimizes component count and board space. Acriche (pronounced ‘Ak rich) comes from the Greek “Acro” which means “the top” and the French “riche” meaning richness.
