The long-afterglow luminous product easy to be excited disclosed by the invention comprises a light collecting layer, a long-afterglow luminous layer and a reflecting layer, wherein the long-afterglow luminous layer is arranged on the right side of the reflecting layer; the right side of the reflecting layer is arranged on the reflecting surface; the light collecting layer is arranged on the long-afterglow luminous layer and composed of a condenser lens or a condenser lens array; the lens adopts a double-side convex lens, a flat single convex lens, a concave and convex lens and a Fresnel lens, and the color of the reflecting surface of the reflecting layer adopts white. A medium layer is arranged between the light collecting layer and the long-afterglow luminous layer according to the requirement; the medium layer adopts a light-transmission material; the structure of the medium layer can adopt a mesh or point structure form; a base material layer is arranged on the back of the reflecting layer; the base material layer adopts a metal material, glass, plastic or wood; release paper is arranged on the back of the reflecting layer, and a durable and transparent protection layer is arranged on the surface of the light collecting layer.

Description

technical field [0001] The invention relates to the field of energy-storage self-luminous material products, in particular to a long-lasting light-emitting product that is easily excited. Background technique [0002] Long afterglow energy storage luminescent material is a kind of photoluminescent material, and its excitation energy is light energy, which can be ambient light, such as: sunlight, light, etc. The basic luminescent principle of this material is that doped elements form luminescent centers and traps in the matrix during the preparation of the material. When excited by external light, the electrons in the ground state of the luminescence center transition to the excited state, and when these electrons transition from the excited state back to the ground state, luminescence is formed. At the same time, some electrons fall into the center of the trap and are bound when excited. After the light is released, the electrons bound in the trap jump out of the trap and f...

Problems solved by technology

However, although this type of fast-absorbing luminescent material improves the light-absorbing speed of the product, the afterglow time is greatly shortened, and the cost is high, which is not easy to be accepted by the market.

So far, there is no public report on a luminescent product that is not only conducive to rapid excitation under weak light sources, but also can be saturated by excitation as much as possible, and can maintain the afterglow characteristics of the long afterglow material itself.
