Blue light is not only present in general light, but is more commonly present in light emitted from various electronic products, such as smart phone screens, computer screens, liquid crystal television screens, or other L ED-related products, etc., and blue light with a stronger intensity than that of a conventional image tube is generally used for maintaining high brightness, furthermore, the white light L ED production technology in the market is mainly divided into two main streams, the first is to use yellow fluorescent powder to convert blue light generated by blue light L ED into white light respectively, which is called Phosphor Converted white light L ED (Phosphor Converted-L ED), the second is multi-chip white light L ED, and white light is formed by combining L EDs of two (or more) different colors, however, the white light L ED commercial product in the market at present time, blue light L ED chip yellow fluorescent powder is most commonly used as a yellow fluorescent powder, so that L ED light source commonly used for illumination in daily life and blue light with high intensity can also be emitted.
Researches show that blue light (short-wave light with the wavelength of 380-500 nm) in visible light can penetrate through the crystalline lens to reach the retina, the retina can generate free radicals after long-term irradiation of the blue light, and the free radicals can cause the retinal pigment epithelial cells to die, so that the photosensitive cells lack nutrients, and finally the vision is damaged. And the degree of damage increases rapidly with decreasing wavelength of the light wave. Blue light has been investigated to prove the most harmful visible light. Medical research also shows that human eyes are not sensitive to visual objects and color discrimination of purple light and partial blue light in the 380-470nm wave band, namely, the eyes have limited color discrimination capability to colored light in the wave band, but the wave band of the light in the wave band is short in wavelength and high in energy, and has great harm to the eyes. Therefore, effective avoidance of irradiation with blue light below 470nm is critical to eye protection.
Therefore, more and more people buy products with blue light resisting function, such as blue light resisting lenses, blue light resisting screens, blue light resisting lamp covers and the like, so as to prevent blue light from damaging eyes of a human body and causing eye diseases (such as macular degeneration); in order to solve the above problems, the prior art uses plastic collagen particles as the main raw material, and processes and forms the outer cover of the lighting lamp by the injection, extrusion or extrusion and pultrusion techniques, however, since the raw material itself does not have the function of absorbing and blocking blue light, a blue light resistant layer is required to be added on the product, or Coating a blue-light resistant film on the product by Coating process (such as Taiwan patent publication No. M463663 "blue-light resistant protective paste composition", it discloses a functional layer and a protective film covering on a substrate, wherein the functional layer contains a blue light blocking agent, so that the protective paste can effectively reduce the damage of blue light to eyes when an object is used, the manufacturing process is complicated, and the brightness of the coated product is reduced, so that the difference in visual brightness is caused, and therefore, the existing blue light prevention material is to be further improved.
