DETAILED DESCRIPTION
(7) To help those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail in combination with particular embodiments below.
(8) The fluorescent film of the present invention is a film made from fluorescent powder. The present invention preferably uses the fluorescent powder or a fluorescent film as a light wavelength conversion component, which can also select different fluorescent powder or fluorescent films to regulate different performance parameters of light according to different requirements, in addition to regulating the wavelength of light. For example, when only a light transmissive binding material is used, the light effect of secondary light emitted by an LED light source can be regulated; and the refractive index of the light transmissive binding material is greater than that of the air, so that the light effect of the secondary light can be changed by changing the angle of light refraction. The light wavelength conversion component can also be used alone, which functions, by means of wavelength convention, to regulate the performance parameters, such as the colour, the proportion of blue light, the colour temperature and the colour tolerance, of the secondary light emitted by the LED light source. The combination of the light transmissive binding material and the light wavelength conversion component can also be further used, especially the fluorescent powder or the fluorescent film, etc., thereby functioning to regulate the performance parameters, such as the colour temperature, the light effect, the colour rendering index, the colour tolerance, the emitted light colour, the proportion of blue light and the fluctuation depth, of the secondary light emitted by the LED light source.

The surface of a label is a layer of hardened transparent thin film, and the middle is a printed pattern layer; and by means of an injection manufacturing process, the back of the label is combined with plastic, with luminescent powder printing ink of the printed pattern layer being sandwiched, so as to prevent the surface of a product from being shaved, and can keep the colour vibrant for a long term without fading easily.
