Definitions
- the present invention relates to an incandescent lamp comprising a tubular glass bulb in which is axially arranged a filament, bulb, each end of which is hermetically sealed by a pinch applied around a metal sheet to which are fixed a outdoor power outlet and a connected indoor power outlet electrically to the filament.
- Such a lamp is used inter alia for cooking food in so-called “glass-ceramic” plates, or for heating applications in industry.
- a lamp according to the preamble above is known from the request for Patent FR 2 454 180.
- An object of the invention is to allow the folding of the bulb without encounter a problem with the alignment of the filament in the bulb during the life of the lamp.
- a second intermediate flat sheet is connected directly at the end of the filament, between the filament and the outlet inside, and the bulb is bent at the level of said second flat sheet.
- a lamp comprises, in a known manner, a bulb in glass 3 of tubular shape, for example quartz glass for a lamp halogen type, in which a filament 4 is disposed axially, and each end of the bulb is hermetically closed by a glass pinch 5 applied around a metal sheet 1 to which are attached a plug external current 7 and an internal electrical outlet 6 connected electrically to the filament 4.
- Pinch 5 is bonded by welding to the bulb tube 3.
- a second intermediate flat sheet 2 is connected directly to the end of the filament, between the latter and the interior outlet.
- the second intermediate flat sheet 2 is in a plane parallel to that of sheet 1, while in the lamp of Figure 1, the second intermediate flat sheet 2 and sheet 1 are in two planes perpendicular to each other: either of these two situations can be used.
- the dimensions of the second flat sheet depend on the electrical current to pass, typically the length is 8mm, the width 4mm, and thickness 0.05mm.
- the bulb of the lamp in Figure 3 is bent at each end, by heating, at the second flat sheet 2, which is itself quite thin to bend while bending the bulb tube. So the external socket 7 is directed in a direction perpendicular to the main axis of the lamp, which may be desired in some applications.
- the filament 4, of the spiral type, is here welded at 9 by one of its turns on the second intermediate flat sheet 2. It is supported at regular intervals on its entire length by known supports 8.
- the lamp has a second intermediate flat sheet and a fold at each end.
