Healthy Lighting

Delta provides various solutions for healthy lighting. Many experiments have confirmed that lighting in line with circadian rhythm can not only improve work efficiency but also improve sleep quality. Delta's LED power supply, luminaire manufacturing, and automatic lighting control technology can simulate the changes in natural lighting that conform to circadian rhythms.

In collaboration with USHIO, a major Japanese light source manufacturer, Delta obtained the Care222® light source that effectively disinfects viruses and bacteria on the surface of objects and in the air with UV light harmless to humans. Delta has developed a variety of products suitable for venues such as major hospitals, clinics, and factory offices.
