Fluorescent lamp tube in rotary central symmetry

Abstract

The invention discloses the method for the design and manufacture of a novel compact fluorescent lamp tube, wherein the two sections of glass tubes bent into a predetermined shape are arranged in plane surface 180 degree rotary symmetry, then are connected into the discharge path of the tube through opposition method. The method according to the invention can be applied to the design and manufacture of lamp tube with lateral S shape discharge passage, which has higher power capacity and light effect with the same size.

Description

Technical field [0001] The invention belongs to the lighting field and relates to the design and manufacture technology of compact fluorescent lamp tubes. Background technique [0002] The planar fluorescent tubes used with lamps such as ceiling lamps are generally single-ring tubes, double-ring tubes, and 2D tubes; among them, 2D tubes have the best lighting effect, but due to the limitations of tube design and manufacturing technology, the largest The power is only 55W, and it is difficult to increase the power to a higher level; in view of the above defects, some people have tried to produce the so-called "2C" lamp tube, that is, two bent lamp tubes are arranged in an axisymmetric manner and connected by the "bridge method". Form the lamp. Its concept is very creative, but it is not accepted by the market because the bridge part of the lamp tube is too easy to break. [0003] The object of the present invention is to introduce a design and manufacture scheme of a novel ...
