Abstract

The invention relates to an electric light source glass method, and especially relates to a preparation method of environmental-protection and low-softening-point lead-free glass products for electric light sources. The low-softening-point lead-free glass products for electric light sources are prepared through the steps of batch preparation, glass melting and mechanical shaping. A rare earth element additive is added to the formula of present lead-free glass to form the components of the batch. An up-conversion luminescence principle is applied to carry out conversion luminescence of infrared lights and ultraviolet lights to realize visible light luminescence; the rare earth additive is simultaneously used as a clarifying agent, a color complementation agent and a conversion luminescence couplant, so the visible light transmittance of the glass is improved; and beryllium oxide and bismuth oxide are added, so the softening point of the glass is further reduced, and the melting and shaping processes and the performances of the products are improved. The glass products have the advantages of high visible light transmittance, ultraviolet and insolation resistances, and no harmful elements.

Description

technical field [0001] The invention relates to a glass method for an electric light source, in particular to a method for preparing a green low softening point lead-free glass product for an electric light source. The invention is mainly applicable to the use of electric light sources. The invention belongs to the technical field of functional glass. Background technique [0002] Electric light source glass is an important basic material for energy-saving lighting source lamps. At present, with the accelerated elimination of incandescent lamps and the national industry orientation of energy conservation and emission reduction, the market for energy-saving lamps is growing at a rate of about 20% every year. and glass covers) demand has a lot of room for development. [0003] The lead-free glass with low softening point for electric light source prepared in the prior art has disadvantages such as high softening point, low light transmittance and low energy utilization effi...
