Abstract
The invention provides a method for producing lamp anti-reflection glass and relates to the technical field of production of lamp glass. The method comprises the following steps of: completely washing and drying lamp glass; coating an anti-reflection coating solution which is synthesized by a sol-gel method on the surface of the lamp glass by a dip-coating method; and after drying at room temperature, placing the lamp glass in the environment at the temperature of 100 to 720 DEG C and solidifying to obtain the anti-reflection lamp glass. Or the method comprises the following steps of: cutting float glass into the specification of the lamp to be produced; edging, completely washing and drying; coating an anti-reflection coating solution which is synthesized by a sol-gel method on the surface of the lamp glass by a dip-coating process; and performing hot press molding on the lamp glass by a thermal pressure method to obtain the anti-reflection lamp glass. The two methods are simple in production process, low in cost and suitable for industrial scale production. The light transmittance of the lamp glass is obviously increased. When the lamp glass is applied to a lampshade cover plate of the lamp, the luminous flux of the lamp is obviously increased, the luminous efficiency of the lamp is improved, and the energy consumption of the lamp is reduced.
Description
Technical field
The present invention relates to light fixture production, particularly relate to the fitting glass production technical field that improves optical throughput.
Background technology
Fitting glass is the important accessory of light fixture, and for the protection of light source, but light is when the glass, can cause the loss of optical throughput due to self absorption of the surface reflection of glass and glass, causes the waste of the energy.Anti-reflective glass is widely used at the show window in indicating meter, solar cell, shop, but the application at fitting glass is less, patent CN102506383 discloses and has adopted vacuum coating method to prepare the method for anti-reflection fitting glass, this method is loaded in workpiece glass on work rest, by transmission system, workpiece is imported vacuum chamber; Be provided with in advance Nb, Si or Ti, Si target in vacuum chamber, then pass into Ar and O to vacuum chamber

2, and be deposited on the surface of workpiece glass, prepare anti-reflection fitting glass.
This method production unit is expensive, and productive expense is high, and plated film can only plate one side at every turn, obtain double-sided coated glass, the glass of the good one side of plating must be cleaned, and then repeats plated film, and production efficiency is low.Antireflecting coating will remain on certain thickness in addition, adopt physical method to be difficult to accurately control the thickness of rete, thereby cause product quality to be difficult to control, and for the fitting glass that obtains by hot pressing, it also has special shape mostly, is difficult to obtain by the mode plated film of vacuum plating.
Summary of the invention
The purpose of this invention is to provide the convenient preparation method who produces, can improve the anti-reflection fitting glass of optical throughput.
A kind of technical scheme of the present invention is: fitting glass is cleaned up and drying, adopt the method for dip-coating, to adopt the synthetic anti-reflection film coating liquid of sol-gel method to be plated on the fitting glass surface, after drying at room temperature is good, the temperature environment that fitting glass is placed in 100～720 ℃ is solidified, and obtains anti-reflection fitting glass.
Another kind of technical scheme of the present invention is: the float glass cutting is become the specification will produce light fixture, through edging, clean up and dry, then adopt the technique of dip-coating, to adopt the synthetic anti-reflection film coating liquid plated film of sol-gel method in the fitting glass surface, then adopt the thermal pressure method that fitting glass is carried out hot-forming, also can obtain anti-reflection fitting glass.
Above two kinds of method production technique are simple, and cost is low, are fit to commercial scale production, the transmittance of fitting glass obviously improves, and is applied to the lampshade cover plate of light fixture, can obviously improve the optical throughput of light fixture, increase the luminous efficiency of lamp, reduced the energy consumption of lamp.
