In traditional underground facilities such as caves and shelters, electric storage emergency lamps are widely used for emergency guidance. However, lamps are with high maintenance and repairing costs, and exist safety risks. Most of current luminous products on the market are made from resin and luminous powder, which has limitations like poor hardness, low abrasion and short service life. In order to improve problems above, our company has cooperated with the Chinese Academy of Sciences, focuses on the area of emergency materials in the dark, and invented the new inorganic light-storage self-luminous material.
