Method of producing a low-pressure mercury vapor discharge lamp |
摘要 |
Method of producing a low-pressure mercury vapor discharge lamp consisting of two or more parallel discharge tubes which are interconnected by means of a cross-connection. In this method two adjacent discharge tubes are interconnected after the inside of the wall of the tubes has been coated with a luminescent layer and after they have been sealed at one end. The connection between the two tubes is then effected by making an aperture with an outwardly extending collar in the wall of each of the tubes, placing the apertures opposite to one another and fusing the collars together.
