Definitions
- ABSTRACT An electric incandescent lamp having a filament, a glass flare, a bulb, a base, a pumping stem for evacuating the bulb during manufacture and electrical conductors connecting the base and the filament.
- the base is connected to the pumping stem, which thus connects the base with the bulb which is located at a distance therefrom.
- the object of the present invention is to solve the aforementioned problem, and to provide an incandescent lamp which when illuminated has the appearance of a candle flame.
- This object is fulfilled by means of the incandescent lamp of the invention which is mainly characterized in that the base is connected to the pumping stem, which thus connects the base with the bulb which is located at a distance therefrom.
- FIG. 1 is a vertical view of an electric incandescent lamp according to the invention in enlarged scale
- FIG. 2 is a vertical view of another embodiment of the incandescent lamp of theinvention.
- FIG. 3 is an enlarged view of a portion of the lamp of FIG. 2.
- the incandescent lamp shown in the figures comprises a bulb l, a base 2, a glass flare 3, a filament 4, a pumping stem 5 for evacuating the bulb during manufacture, and electrical conductors 6 and 7 which connect the base to the filament.
- the pumping stem opens out into the bulb through an orifice 8 in the glass flare.
- the filament is supported by a support member 9, the free end of which abuts the inside of the bulb.
- the base 2 is connected direct to the pumping stem 5 instead of to the bulb. In this way it is possible to make the base very small, as shown in FIG. 2
- a standard base can be fitted and a narrow neck portion obtained between the bulb and the base.
- the bulb can be made long and narrow, to present a candle flamelike fon'n without a visible attachment to impair the appearance.
- the bulb and the glass flare extend freely around the pumping stem towards the base.
- the pumping stem can be surrounded above the base by an insulating sleeve 10, which, for example, can be darkly colored to simulate in the embodiment of FIG. 1 a candlewick, and in the embodiment of FIG. 2 the dark core flame.
- the sleeve also surrounds the electrical conduits and thus also forms a protective cover for the same.
- the base can also be darkly colored to give the impression of a wick.
- the glass flare can be darkly colored, to simulate the dark core flame.
- FIG. 1 is intended for standard fittings for Christmas tree illuminations etc., and is therefore provided with a standard base.
- the embodiment of FIG. 2 is intended for chandelier lighting with a special base, which can also be movably arranged to simulate the fluttering of a candle flame.
- An electric incandescent lamp including a filament, a glass flare, a bulb connected to said flare and surrounding said filament, a base, a pumping stem for evacuating the bulb during manufacture and electrical conductors connecting the base and the filament, wherein the base is fixed to one end of the pumping stem and the glass flare is mounted on the pumping stem at a point spaced from the base whereby the pumping stem provides the connection between the base and the glass flare, so that the lamp provides an illusion of a wick with a flame when the lamp is on.
- a lamp is claimed in claim 1, including a sleeve arranged between the base and the bulb and surrounding the pumping stem and the electrical conductors.
