In this document, we introduce case studies of the implementation of "iEL." At a major steel plant in Nagoya, product defects that were not visible with LED lighting have become much easier to see, resulting in zero complaints. Additionally, various reputable companies are continuously adopting this technology, including a major electronics manufacturer in Mito, a major printing machinery manufacturer in Tsukuba, and a major tire manufacturer in Fukuoka Prefecture. 【Implementing Companies】 ■ Comprehensive heavy machinery manufacturer Company I ■ Major steel manufacturer Company J ■ Major automobile manufacturer Company T ■ Major automobile dealer Company H ■ Comprehensive logistics trading company Company N *For more details, please refer to the PDF document or feel free to contact us.

The "iEL" has no glare or dazzling brightness. It eliminates the diffuse reflection (making surfaces appear blurred) that occurs on object surfaces due to the angle of illumination, making it easier to check for fine scratches and unevenness. It is an essential condition for inspection and quality control tasks, creating no strong shadows at hand or foot level, making it suitable for spaces such as factories, warehouses, and sports facilities. 【Features】 ■ Bright but not glaring ■ High-quality light that suppresses diffuse reflection and makes small scratches easy to see ■ Prevents oversight, avoids dangers in advance, and improves work efficiency ■ Significant energy savings and high color rendering are excellent ■ The way objects appear is the key ■ The light is soft and suitable for on-site use *For more details, please refer to the PDF document or feel free to contact us.

A safe and secure neutral disinfectant (surfactant) developed with cosmetic ingredients. "Glycine" is a component found in natural scallops and shrimp, and is commonly used in shampoos and lotions. Thanks to the unique technology of a major domestic cosmetic ingredient manufacturer, glycine with excellent penetration and disinfection power has been successfully developed. It possesses outstanding penetration and disinfection capabilities, making it effective for cleaning dirt, disinfecting, and preventing mold. Glycine is used as a component in disinfectants and sterilizers due to its high disinfection effectiveness, including for surgical instruments and infection prevention. Regarding the novel coronavirus, experts suggest that "surfactants" found in "soap" or "household neutral detergents" can be effective even without alcohol disinfectants. The "novel coronavirus" is very similar to the "SARS virus," both sharing a common "envelope," which is a "lipid membrane." Alcohol destroys this "envelope," eliminating the virus's infectivity, but the National Institute of Infectious Diseases has announced that the same effect has been confirmed for the "SARS virus" using "surfactants." While it has not yet been confirmed through experiments for the current "novel coronavirus," similar effects are expected. (Refer to NHK Asahi's website)
