Abstract
The invention discloses low-refractive index titanium dioxide anti-reflection photo-permeability-increased illumining lamp coated glass. A porous titanium dioxide coating film on the surface of the illumining lamp glass has the characteristic of lower refractive index, and has the principle that the refractive index of the air is 1. A method for obtaining the material with lower refractive index comprises the step of forming the porous structure titanium dioxide coating film by a synthesis technology of low-refractive index titanium dioxide sol, wherein the refractive index of a hole is the proportion combination between the refractive index 1 of the air and the used low-refractive index material. According to the mode, the coated glass has the characteristics of being anti-reflection and higher in photo-permeability, and is better in ageing resistance, and the illumining brightness of the illumining lamp glass can be greatly improved due to the photocatalysis efficiency of a photocatalyst.
Description
Technical field
The present invention relates to light fixture coating technique field, particularly relate to a kind of surface through the anti-reflection optical illumination fitting glass of antireflective of low-refraction TiO 2 sol coating film treatment.
Background technology
Illuminating lamp is the indispensable commodity during people live.At present, the illuminating lamp occurring in market and data is mainly by lamp housing, the lampshade that is arranged at the illuminator in lamp housing and is connected with lamp housing, lampshade is provided with the light penetrating object that the light source for illuminator sees through, conventionally, light penetrating object is the glass of individual layer, and in use, the light source being seen through by single-glass body is even not, easily cause dazzle, affected illuminating effect.
Titanium deoxid film has the characteristic that refractive index is high, and wherein rutile-type crystallization refractive index approximately 2.71, anatase titanium dioxide crystallization refractive index approximately 2.55, and therefore, titanium deoxid film has larger reflection and the ability of scattered light.
When incident light passes through glass surface plated film, there are refraction and reflection to produce, when the light of refraction arrives at glass interface, also have refraction and reflection.Second reverberation R2 has walked film plating layer thickness distance twice than first reverberation R1 more.The optical thickness of supposing plated film is d, and the optical path difference of R1 and R2 is 2d, and when optical path difference 2d equals the odd-multiple of half wavelength, the catoptrical phase difference of twice will be 180 °, produces destruction interference and cancels each other.From law of conservation of energy, reduce reverberation and can increase penetrating light.So when 1/4th odd-multiple that the optical thickness of plated film is optical wavelength, the reflection of light rate convergence that just can make its wavelength is zero.To one fixedly the thickness of plated film can only produce interference effect to the light of fixed wave length, the light that is different from this wavelength has higher reflectivity.Except the thickness of plated film, the material of plated film is also very important, the desirable refractive index of film
n=
, wherein
nairfor air refraction,
nglassfor glass refraction.
The way of antireflection film is divided into two large classes, and the 1st class is to form sandwich construction with the mutual storehouse of material of different refractivity together, or by controlling the thickness of storehouse and the refractive index of material.Differ quarter-wave light wave while touching together when two, will produce complete destruction interference, the light of reflection is offseted.Therefore, if the THICKNESS CONTROL of plated film at 1/4th of visible wavelength, can reach anti-reflective effect.The 2nd large class is called low-reflection film, when light enters glass substrate by air, the refractive index of known air (
nair=1) and the refractive index of glass (
nglass=1.52), from air and substrate interface, reflect, the reflection that double-sided glass causes is approximately 7 ~ 8%.
Cellular structure low-refraction antireflective TiO 2 coating film has lower refractive index characteristic, its principle because of the refractive index of air be 1, want to obtain material to be made to loose structure compared with the method for low-index material, the refractive index at hole place is the ratio combination of the refractive index of the refractive index 1 of air and the material that uses.
Owing to not yet there being the technical products of the anti-reflection optical illumination light fixture of low-refraction titanium dioxide antireflective coated glass, and low-refraction titanium deoxid film is that an important technology is broken through in antireflective application, therefore, developing the anti-reflection optical illumination light fixture of low-refraction titanium dioxide antireflective coated glass is main purpose of the present invention.
