Glass tube of novel high-efficiency energy-saving lamp

Abstract

The invention discloses a glass tube of a novel high-efficiency energy-saving lamp, comprising the following components in percentage by mass: 67.2-67.5 percent of SiO2, 10.3-10.9 percent of Na2O, 5.6-6 percent of PbO, 5.1-5.3 percent of K2O, 3.9-4.1 percent of BaO, 2-2.3 percent of B2O3, 2.1-2.3 percent of Al2O3, 3.1-3.4 percent of CaO and 0.2-0.5 percent of MgO. When used, the invention greatly reduces lead content in a lamp tube and dust precipitation quantity of red lead at the same time and lightens environmental pollution.

Description

technical field [0001] The invention relates to an energy-saving lamp glass tube. Background technique [0002] As we all know, electric light source products are generally glass products, and lead glass is usually used. Lead glass is divided into light red lead (low lead) glass according to the PbO (red lead) content, and its content is 11%; medium red lead (medium lead) glass Glass, its content is 20% and heavy red lead (high lead) glass, its content is 28%. Because of the needs of glass processing, all kinds of energy-saving lamps use low-lead glass, generally lead glass with a lead content of 11%. The lead in lead glass is introduced by adding lead oxide or lead silicate in the batching process. During the use of lead glass, the dust of red lead will slowly precipitate out, seriously polluting the environment. Contents of the invention [0003] The object of the present invention is to provide a new type of high-efficiency energy-saving lamp glass tube, which can eff...
