Definitions
- the invention relates to a lamp and a lamp with a reflector and such lamp.
- the lamp in this case comprises a bulb, which has a bulb axis has and encloses a main spiral and a secondary spiral, the spiral axes are aligned parallel to the piston axis, and a socket with means for Definition of an installation position with regard to the piston axis.
- the means to define Definition of the installation position at least one "up" position.
- the Invention a corresponding lamp with a reflector and a lamp holder, in which such a lamp is arranged and which has devices which with the means for defining the installation position cooperate such that the lamp only can be arranged in a desired installation position in the lamp holder.
- Such incandescent lamps are used advantageously, particularly in motor vehicle headlights
- Low beam and high beam can be generated by a single light bulb without the lamp by means of complex adjusting mechanisms and motors between a dimming and having to move to a high beam position.
- spirals have to have a certain minimum distance from each other so that when operating a Spiral, in which tungsten atoms are evaporated, does not lead to undesirable deposits on the other, unused spiral comes.
- every spiral a certain minimum distance to the inside of the usually made of a glass and rotationally symmetrical burner pistons (including as burner glass designated).
- the problem with the known lamps is that - due to the arrangement the filaments - the diameter of the burner bulb can be chosen to be relatively large must have a large volume in the piston and therefore a lower maximum pressure of a gas enclosed in the piston, a high pressure of the gas being desired is, because of this the evaporation of the lamp which reduces the lifetime of the lamp Tungsten atoms from the filaments can be reduced.
- the invention is based on the object of a lamp or luminaire Specify the type mentioned, in particular a vehicle headlight lamp, at which the piston diameter and thus the piston volume is reduced, so the positive effects of a high gas pressure and the lifetime of the lamp to extend.
- a lamp in particular a high-performance two-filament incandescent lamp, with a piston having a piston axis and a main coil and encloses a secondary spiral, the spiral axes of which are aligned parallel to the piston axis is, as well as with a version with means for defining an installation position with respect to the Piston axis, the means for defining the installation position at least one "up" position define.
- This lamp is characterized in that the piston axis with respect the helix axis of the secondary helix is offset both vertically and horizontally.
- the invention is therefore based on the knowledge that the helix axis of the secondary helix be staggered both vertically and horizontally with respect to the piston axis can, whereby the double offset allows the diameter of the piston and thus that reduce the volume enclosed by the piston. In this way, the light output can be significantly increased in a lamp according to the invention.
- piston axis describes a main longitudinal direction the lamp combustion chamber or the lamp bulb.
- the piston in the is essentially cylindrical and the piston axis of the cylinder axis corresponds.
- the helix axes can preferably both the secondary helix and the main helix be offset with respect to the piston axis. This applies in particular to both horizontal as well as a vertical offset and enables a reduction in the piston diameter.
- the secondary helix is preferably arranged in such a way that it is intended Operating condition between 0.3 and 1.3 mm next to the vertical, including the piston axis Level, on the side of this level opposite the main spiral is arranged. In addition, it can be between 0.1 and 1.1 mm below the horizontal, the plane including the piston axis.
- the holding wires which hold the wires of the coils, are preferably in one plane, preferably the sealing plane. In this way, these retaining wires can be proportionate be short. This leads to a particularly precise and shockproof Overall arrangement.
- the Coils can be arranged so that they rest on the plane of the main wires or cut these. With such an arrangement, the helix wires can be extended without the necessary offset of the coils can be realized.
- 1 to 4 is a high-performance two-filament incandescent lamp, designated in its entirety by 10 shown for use in a reflector, not shown, wherein the incandescent lamp is arranged essentially parallel to one another in a burner bulb 12, by means of corresponding current conduction means 14, alternately operable filaments 16 and 18 includes.
- a filament 16 as the main filament and the other helix 18 is referred to as a secondary helix.
- At one end of the piston 12 is one known version 20, at the opposite end an opaque absorption zone 22 provided.
- the two filaments are towards one another Main axis of the filaments and thus in the direction of the main axis of the bulb 12 and the reflector, not shown, arranged offset, in this embodiment by 2 mm, measured from the upper edge facing the reflector cap 22 of the spirals.
- the piston is designed as intended State of use an offset transverse to the main or central axis of the Secondary helix 18 and thus to the optical axis of the reflector, not shown, on the optical axis in Fig. 4 perpendicular to the secondary helix 18 from the plane of representation points out while the piston axis from the intersection of the dash-dotted lines points out of the drawing.
- the main coil 16 is about 2 mm to the right of a vertical, the piston axis of the reflector-enclosing plane, while the secondary helix 18 0.8 mm approximately to the left is next to this level.
- both coils are also below a horizontal plane including the piston axis, the main spiral 16 about 2.6 mm, the secondary helix 18 is 0.6 mm below this level.
- the sealing plane is also opposite the horizontal or Vertical arranged at an angle. This can be seen in particular from FIG. 4.
- the angle is 45 ° and is selected such that both Spirals 16, 18 the sealing plane and thus the plane in which the holding wires 14 are arranged, touch or cut lightly. In this way, the necessary Offset can be ensured solely by the helix wires, while the holding wires 14 can be as short and stable as possible. In this way, the overall arrangement builds extremely stable and precise.
