Products using Acrich technology

Acrich is the technology necessary to realize high voltage and high output. Recently, with the increasing demand for high voltage LEDs above 12V in the lighting field, Acrich's technology has been applied to a wide range of lighting products such as street lamps and LED filament lamps. The more extensive. In addition, Acrich's technology facilitates local dimming, while local dimming improves shading performance, so Acrich's technology is also widely available in high-definition (UHD: Ultra High Definition) high-priced TV products. use.
