Impact of damaging and recovery on the temperature dependence of the work function of oxide electrodes in fluorescent lamps

Autor: Reinhard Langer, Reinhard Tidecks, Irina Paul

Publikováno v: The European Physical Journal Applied Physics. 96:11301

In the present work the work function of electrons for oxide cathodes in operating fluorescent lamps is measured before and after damaging the cathodes by cold starting of the lamp. A strong increase of the absolute value and a decrease of the temper

Preheated ignition and work function studies on alkaline earth metal oxides coated tungsten electrodes of fluorescent lamps

Autor: Reinhard Langer, Farrukh Dar, Achim Hilscher, Siegfried Horn, Reinhard Tidecks

This paper describes measurements on the alkaline earth (Ba, Sr, Ca) oxide layers utilized as emitting material in fluorescent lamp electrodes. In a first approach we compared the emission capabilities of the different materials (BaO, SrO and CaO coa

Cold starting of fluorescent lamps – part II: experiments on glow times and electrode damaging

Autor: Reinhard Langer, Siegfried Horn, Achim Hilscher, Irina Paul, Reinhard Tidecks

Publikováno v: The European Physical Journal Applied Physics. 76:30802

In the present work we present experiments on cold start and the resulting electrode damaging (reducing lamp life) of AC driven fluorescent lamps. The crucial parameter is the glow time, determined from time resolved measurements of lamp voltage and

Cold starting of fluorescent lamps – part I: a description of the transient regime

Autor: Reinhard Tidecks, R.C. Garner, Reinhard Langer, Irina Paul, Siegfried Horn

Publikováno v: The European Physical Journal Applied Physics. 76:10802

In this paper we give a proposal for the transient behaviour of a cold-started fluorescent lamp, from the generation of the first conductive channel over the normal and abnormal glow discharge and the glow-to-arc (GTA) transition to the arc discharge
