Abstract

The proposal is for a power-saving lamp with transverse reinforcement (4 or 5) joining the glass loops together, thus rendering them less sensitive to transverse forces.

Description

/07259 _ 1 Energiesparlampe/ 07259 _ 1 energy saving lamp
Die Erfindung betrifft Energiesparlampen mit schlaufenformigen Glaskörpern.The invention relates to energy-saving lamps with loop-shaped glass bodies.
Bei Energiesparlampen mit mehr als einer aus dem Sockel 1 des Zündgerätes herausragenden schlaufenformigen Glasröhren 3 besteht das Risiko, dass bei der Glasverbindung 2 an der Basis leicht Spannungsrisse entstehen können, wenn an den Schlaufen-Enden eine laterale Kraft ausgeübt wird. Dieses Problem tritt vor allem bei der Montage, Demontage oder bei Quer-Beschleunigungskräften beim Umschlag und Transport auf, was bisher oft zur Funktionsuntüchtigkeit und zum Austritt von Gasen geführt hat.With energy-saving lamps with more than one loop-shaped glass tube 3 protruding from the base 1 of the igniter, there is a risk that stress cracks can easily occur at the base of the glass connection 2 if a lateral force is exerted at the loop ends. This problem occurs especially during assembly, disassembly or with transverse acceleration forces during handling and transport, which has often led to inoperability and the escape of gases.
Figur 1 zeigt eine typische Stromsparlampe der neueren, superkompakten elektronischen Art, bei der die Glasröhren mit der Fluoreszenzbeschichtung in paralleler Doppel-Anordnung U- formig ausgebildet sind. In der linken Seitenansicht ist die bisherige Ausführung mit dem offenen Spalt bis zur Verbindungsstelle 2, rechts die verbesserte, mit kraftschlüssiger Verbindung 4 versehene Ausführung dargestellt.FIG. 1 shows a typical energy-saving lamp of the newer, super-compact electronic type, in which the glass tubes with the fluorescent coating are designed in a U-shape in a parallel double arrangement. In the left side view the previous version with the open gap up to the connection point 2 is shown, on the right the improved version provided with a non-positive connection 4.
Figur 2 zeigt den Glasteil einer Lampenvariante ge äss Patentanspruch beispielsweise mit vier U-formigen Schlaufen auf der linken Seite un drei verschiedene Varianten der Gestaltung des oberen Teils auf der rechten Seite.Figure 2 shows the glass part of a lamp variant according to claim, for example with four U-shaped loops on the left side and three different variants of the design of the upper part on the right side.
Typische Anordnungen des Patentgegenstandes sind aus Fig. 1 und 2 ersichtlich, wobei zu beachten ist, dass doppelte, dreifache oder mehrfache Schlaufen-Konfigurationen mit den Formen A, B oder C in Figur 2 möglich sind.Typical arrangements of the subject matter of the patent can be seen from FIGS. 1 and 2, it being noted that double, triple or multiple loop configurations with the shapes A, B or C in FIG. 2 are possible.
Durch eine kraftschlüssige Verbindung zwischen den Enden 3 (Fig 1 und 2) der Schlaufen kann das Risiko eines Glasbruchs wesentlich reduziert werden. Dies kann entweder durch Verschmelzen eines Glastropfens 4 zwischen den Schlaufen erfolgen oder durch gegenseitige Neigung der Schlaufen, sodass diese sich berühren und an der Berührungsstelle 5 verschmolzen werden können. Solche kraftschlüssige Verbindungen können mit geringen Kosten angebracht werden und bringen einen Nutzen im mehrfachen Betrag durch Reduktion von Garantie- Reklamationen und Austauschkosten, nebst der Entlastung der Umwelt durch unkontrolliert austretende Gase und/oder Quecksilber. The risk of glass breakage can be significantly reduced by a non-positive connection between the ends 3 (FIGS. 1 and 2) of the loops. This can be done either by melting a glass drop 4 between the loops or by mutual inclination of the loops so that they touch and can be fused at the point of contact 5. Such positive connections can be installed at low cost and bring multiple benefits by reducing warranty complaints and replacement costs, as well as relieving the environment from uncontrolled escaping gases and / or mercury.
