What Are Inorganic Light-Accumulating Self-Luminous Materials and the Applications of Self-Luminous

　　Inorganic light-accumulating self-luminous materials are long twilight light-storing materials. They are made by sintering various inorganic minerals as substrates with rare earth ions as activators at ultra-high temperatures of thousands of degrees, and can continuously emit light in the dark after being excited by light energy. Known as an electricity-free natural light source, they are core innovative materials widely used in emergency safety and green lighting fields.

I. Derivative Product Matrix of Inorganic Light-Accumulating Self-Luminous Materials

　　Based on inorganic light-accumulating self-luminous materials, Globright Optics has built a complete "Luminescence Plus" product ecosystem.

　　The product series includes inorganic light-accumulating self-luminous wall and floor tiles, inorganic light-accumulating self-luminous plates, inorganic self-luminous particles, inorganic self-luminous sign boards, inorganic self-luminous anti-slip boards, inorganic self-luminous color plates, inorganic self-luminous camouflage plates, inorganic self-luminous marking lines, inorganic self-luminous power signs, inorganic self-luminous water conservancy signs and more. Besides, luminous powder can be used as base material and added into coatings, plastics and ceramics to develop various finished products, such as luminous paint, luminous plastic toys, luminous cups and other luminous supplies.

II. Luminescence Principle and Essential Characteristics of Self-Luminous Materials

　　1. Luminescence Principle

　　Simply put, these materials can absorb light under any visible light environment, including natural light on sunny and cloudy days as well as indoor lighting. It takes about 5 to 20 minutes to finish light storage, and higher illuminance shortens the light absorption time. After sufficient light storage, they can keep emitting light for more than 10 hours in darkness, realizing all-weather safety warning and direction guidance round the clock.

　　2. Core Characteristics

　　Non-toxic, radiation-free and environmentally friendly, non-combustible, high hardness with excellent wear resistance, anti-aging, anti-corrosion, wide temperature resistance ranging from -40℃ to 180℃, long self-luminous duration and stable optical performance.

III. Industrial Application Scenarios of Inorganic Self-Luminous Derivative Products

　　1. Public Safety and Emergency Response Field

　　Fire Evacuation: In case of power failure caused by fire accidents, self-luminous signs can provide escape route guidance lighting for over 10 hours, mainly including emergency indicator signs and evacuation guide marking lines.

　　Municipal Tunnels: They can replace part of electric-powered signboards, effectively reduce operation and maintenance costs and improve urban landscape, covering self-luminous signage and guide lines.

　　2. Transportation Infrastructure

　　Rural Roads: Luminous marking lines greatly improve visibility in rainy and foggy weather to lower traffic accident risks, including self-luminous road studs and all kinds of self-luminous traffic marking lines.

　　Rail Transit: Applied to metro platform edges, stair treads for anti-slip treatment and warning in high-risk areas via self-luminous marking signs.

　　3. Green Buildings and Cultural Tourism Industry

　　Zero-carbon Buildings: Served as passive self-luminous design elements to cut down night power consumption, mainly adopting self-luminous identification signs.

　　Night Tour Economy: Widely used for scenic trails and wetland park starry sky walkways (taking Jinhua Baideli night tour trail as a typical case), including luminous pavement, luminous marking lines and customized self-luminous patterns and texts.

　　4. Power Industry and Special Industrial Fields

　　Substation Facilities: Apply non-electromagnetic interference and explosion-proof self-luminous sign systems for warning lines in high-risk areas.

　　Water Conservancy Engineering: Suitable for dam inspection marks and water level gauges, adaptable to water immersion and corrosive environments, including self-luminous inspection marking lines, luminous water level rulers and special regional self-luminous signs.

　　To sum up, inorganic self-luminous materials are long twilight light-storing materials that can emit light stably and independently in dark conditions. This new type of material was officially released by Zhejiang Globright Optics Technology Co., Ltd. at the main venue activity of Zhejiang National Popular Science Day in 2018. Its diversified derivative products bring brand-new solutions and development opportunities for all walks of life.
