Spontaneous light material is a kind of functional material can glow in dark environment, it relies on absorb light energy and the principle of slow release of fluorescent or afterglow effect. Choose appropriate self-luminous materials, need to consider its luminous effect, time and applicability of luminescence. First of all, the glowing effect directly determine product visual effect. At present common self-luminous materials are blue powder, green and red powder, etc., can produce, blue, green and red fluorescence. Blue and green fluorescence effect is downy and bright, suitable for the identification and warning; Red fluorescence effect is more prominent, often used in emergency exit and other places of warning. In addition, the luminous intensity is also a important factor, high brightness material can produce a strong visual impact. Second, the luminous time directly affects the service life of the product. General requirements light-emitting time in 6 to 12 hours, high-performance products can reach more than a day's time. Light-emitting products with long time service life is longer, but the cost is higher also. Therefore, according to the actual application needs to choose the appropriate light time. Furthermore, the applicability of the self-luminous materials also need to consider. It must have high chemical stability and light fastness, color shading is not easy to happen and performance attenuation. At the same time, the self-luminous material also should have good mechanical strength and adhesion, can be closely combined with base material for a long time. In addition, non-toxic harmless also is vital to choose the self-luminous materials, especially used in confined Spaces. All in all, choosing the self-luminous material should be considered using various factors such as purpose, technical performance and economic benefit. High-performance self-luminous materials can produce the ideal visual effect and longer luminescence time, but the cost is higher also. Can also according to the actual need to select cost-effective products. No matter seem а seem, security, environmental friendliness and stability are important standard judgment illuminated material. With the development of science and technology, the self-luminous material performance and species are also increasing. Believe that through the overall understanding of the different products and summary, can choose the most suitable self-luminous materials, to achieve the ideal decorative effect or instruction. It also provides related industries with more broad space for development
