Abstract

The invention discloses an optical film with a blue light inhibition function. The optical film comprises a transparent substrate which is in a diaphragm film form with a thickness, an area and light transmittance and consists of a first surface and a second surface, a bottom coating arranged on the first surface or the second surface of the transparent substrate, and an anti-blue-light optical surface layer which is molded in a form through glue applying and additionally arranged on the surface of the bottom coating, and is transparent. The structure of the anti-blue-light optical surface layer is uniformly mixed with anti-blue-light fine particles which have a light diffusion effect and can inhibit blue light within the wavelength range from 380nm to 500nm in light rays to a certain extent. Thus, the optical film has a blue light inhibition function with the aid of the technical characteristics of the anti-blue-light fine particles in the structure of the anti-blue-light optical surface layer, and the adverse effects caused by blue light produced by LED products can be significantly reduced.

Description

There is the blooming suppressing blue light function

Technical field

The present invention relates to a kind of blooming; In particular to a kind of, there is the blooming suppressing blue light function.

Background technology

In recent years, traditional type light fixture and light source all have by the situation in LED product fast fetching generation, but also because so, the probability touching blue light in people's living environment is caused also relatively to increase, described " blue light ", refer to the high light of a kind of area of light between 380nm to 500nm wavelength, because its ripple is longer than shorter in visible light, there is height energy, point out through current relevant medical report, if human eye is through the long-time irradiation of blue light, easily cause retinal damage, eye strain, eyesight reduces and age-related macular degeneration, the illnesss such as sleep-disorder, as can be seen here, along with the generally use of LED product, the negative effect that blue light produces human body, vast use consumer certainly will be become next must pay close attention to and the major issue of worrying.

With regard to current visible LED product on the market, if LED is applied on fitting structure, the problem of its blue light perhaps can construct through the refraction at lampshade position or reflective etc. solves easily or improves, but, when LED applies the backlight as various liquid crystal display, directly inject user's eyes because its blue light outwards can appear from glass metal crystal panel, therefore in this case, blue light for the injury of user's eyes in fact not second to aforementioned LED lamp, generally no matter live because of current majority or work, be the state of long-time visual liquid crystal display, and in current visible lcd products structural design, do not consider and the problem solving described blue light, the great shortcoming of real genus.

Summary of the invention

Fundamental purpose of the present utility model is that providing a kind of has the blooming suppressing blue light function.

For achieving the above object, the present invention by the following technical solutions:

Have and suppress the blooming of blue light function to comprise: a transmitting substrate, for having the membrane body form of a thickness, area and light transmission, this transmitting substrate comprises a first surface and a second surface; One undercoat, is located at first surface or the second surface of transmitting substrate; The optics top layer of one anti-blue light, set up in base coating surface for jelly coating is combined into form sample, the optics top layer of this anti-blue light has light transmission; And wherein, in the optics surface structure of this anti-blue light, Homogeneous phase mixing has anti-blue light particulate, described anti-blue light particulate has light diffusion, can to the blue light of light medium wavelength between 380nm to 500nm generation inhibition to a certain degree.

Main efficacy results of the present invention and advantage, can by being mixed with the atomic technical characteristic of anti-blue light in the optics surface structure of this anti-blue light, make blooming have and suppress the function of blue light, significantly can reduce harmful effect and special tool practical improvement that blue light that LED product sends causes.

Embodiment

Refer to shown in Fig. 1,2, the present invention has the preferred embodiment of the blooming suppressing blue light function, and only these embodiments are only for explanation, and patented claim is not subject to the restriction of this structure; Described blooming A comprises following formation:

One transmitting substrate 10, for having the membrane body form of a thickness, area and light transmission, this transmitting substrate 10 comprises first surface 11 and a second surface 12;

One undercoat 20, is located at first surface 11 or the second surface 12 of transmitting substrate 10;

The optics top layer 30 of one anti-blue light, set up in undercoat 20 surface for jelly coating is combined into form sample, the optics top layer 30 of this anti-blue light has light transmission; And wherein, in optics top layer 30 structure of this anti-blue light, Homogeneous phase mixing has anti-blue light particulate 40(TECHPOLYMER), as shown in Figure 3, described anti-blue light particulate 40 has light diffusion (as shown in arrow L1), can to the blue light of light medium wavelength between 380nm to 500nm (as shown in arrow L2) generation inhibition to a certain degree; By this, made blooming A have and suppressed the function of blue light (the difference in size change that please contrast arrow L2, L3 is shown).

Wherein, this transmitting substrate 10 can select PET, PC material to form.

Wherein, the surface on the optics top layer 30 of this anti-blue light can be plane, tool diffusion unit, at many levels brightened type let alone middle a kind of form; The optics top layer 30 of the concrete anti-blue light as shown in Figure 1, 2 of this part, is set to plane configuration; The optics top layer 30B of another anti-blue light as shown in Figure 4, is set to the form of tool diffusion unit 31; The optics top layer 30C of anti-blue light as shown in Figure 5 again, be set to multi-level blast form, these optics top layers being this anti-blue light can specific embodiment.
