Description
Technical field
The utility model relates to light fixture coating technique field, particularly relates to a kind of surface through the anti-reflection optical illumination fitting glass of the antireflective of low-refraction TiO 2 sol coating film treatment.
Background technology
Head light is the indispensable daily necessities during people live.At present, the head light that occurs on market and the data mainly by lamp housing, be arranged at the twinkler in the lamp housing and the lampshade that is connected with lamp housing, lampshade is provided with the light penetrating object that the light source for twinkler sees through, usually, light penetrating object is the glass of individual layer, and is in use, even inadequately by the light source that the single-glass body sees through, cause dazzle easily, influenced illuminating effect.
Titanium deoxid film has the high characteristic of specific refractory power, and wherein rutile-type crystallization specific refractory power is about 2.71, and anatase titanium dioxide crystallization specific refractory power is about 2.55, and therefore, titanium deoxid film has bigger reflection and the ability of scattered light.
When incident light passes through the 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.The second road reflected light R2 has walked coatings thickness distance twice than the first road reflected light R1 more.The optical thickness of supposing plated film is d, and then the path difference of R1 and R2 is 2d, and when path difference 2d equals the odd-multiple of half wavelength, the catoptrical phase differential of twice will be 180 °, produces destruction interference and cancels each other.From law of conservation of energy, reducing reflected light then can increase and penetrate light.So when the optical thickness of plated film was 1/4th odd-multiple of optical wavelength, the reflection of light rate convergence that just can make its wavelength was zero.Fixedly the thickness of plated film can only be to the light generation interference effect of fixed wave length to one, and the light that is different from this wavelength has higher reflectivity.Except the thickness of plated film, the material of plated film also is very important, the desirable specific refractory power of film
N=
, wherein
NairBe air refraction,
NglassBe glass refraction.
The way of antireflection film is divided into two big classes, and the 1st class is to form multilayered structure with the mutual storehouse of the material of different refractivity together, or by the thickness of control storehouse and the specific refractory power of material.Differ quarter-wave light wave when bumping together when two, will produce complete destruction interference, the light of reflection is offseted.Therefore, if the gauge control of plated film at 1/4th of visible wavelength, can reach anti-reflective effect.The 2nd big class is called low-reflection film, when light during by the air admission glass substrate, the specific refractory power of known air (
Nair=1) and the specific refractory power of glass (
Nglass=1.52), reflect from air and substrate interface, then the reflection that causes of double-sided glass approximately is 7 ~ 8%.
Cellular structure low-refraction antireflective TiO 2 coating film has lower refractive index characteristic, its principle is 1 because of the specific refractory power of air, the method of wanting to obtain than low-index material can be made vesicular structure to material, and the specific refractory power at hole place then is the ratio combination of the specific refractory power of the specific refractory power 1 of air and the material that uses.
Because the technical products of the anti-reflection optical illumination light fixture of low-refraction titanium dioxide antireflective coated glass is not arranged as yet, and the low-refraction titanium deoxid film is that an important technology is broken through in the antireflective Application Areas, therefore, developing the anti-reflection optical illumination light fixture of low-refraction titanium dioxide antireflective coated glass is main purpose of the present utility model.
