Definitions
- the present invention relates to an incandescent lamp comprising a glass bulb of tubular shape in which is arranged axially a filament, bulb of which each end is hermetically closed by a pinch applied around a metal sheet to which are attached a external power outlet and a connected indoor power socket 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 application of FR 2 454 180.
- An object of the invention is to allow the folding of the bulb without have trouble 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 latter and the socket inside, and the bulb is bent at the level of said second flat sheet.
- FIG. 1 represents a lamp according to the invention, before the bulb is bent.
- FIG. 2 represents, seen from above and from the side, the end of the lamp of Figure 1.
- Figure 3 shows in more detail the end of the finished lamp.
- a lamp comprises, in a known manner, a bulb in glass 3 of tubular form, for example quartz glass for a lamp of halogen type, in which is arranged axially a filament 4, and each end of the bulb is sealed by a glass nip 5 applied around a metal sheet 1 to which are fixed a external current 7 and an indoor electrical outlet 6 electrically connected to the filament 4.
- the nip 5 is welded to the tube of the bulb 3.
- a second intermediate flat sheet 2 is connected directly to the end of the filament, between the latter and the indoor socket.
- the second intermediate flat sheet 2 is in a plane parallel to that of sheet 1, whereas in the lamp of FIG. second intermediate flat sheet 2 and sheet 1 are in two planes perpendicular to each other: either of these two situations may to be used.
- the dimensions of the second flat sheet depend on the electrical intensity to be passed, typically the length is 8mm, the width 4mm, and thickness 0.05mm.
- the lamp bulb of Figure 3 is bent at each end by heating, at the level of the second flat sheet 2, which is itself quite thin to bend while bending the tube of the bulb. So the external outlet 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 flat intermediate 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 folding at each end.
