Definitions

  • the invention is based on an electric light bulb, in particular one Halogen incandescent lamp, with IR reflection layer according to the preamble of Claim 1.
  • incandescent lamp with a flat one Luminous body, a so-called flat core filament.
  • the cross section of Flat core filaments have not, like the filament of incandescent for General lighting, a circular cross section, but rather an elongated cross section.
  • the reason for this is the adjustment of the Geometry of the spiral shape to the preferred for the respective main area of application Radiation characteristics of the lamp or filament.
  • the difference for rotationally symmetrical radiation characteristics of conventional Incandescent lamps are made possible by the flat luminous body of the aforementioned Lamp types emphasize areal radiation, such as for technical-scientific lighting purposes as well as in photo optics, especially for projection purposes.
  • Typical electrical Power values are in the range of approx. 50 to 400 watts.
  • the one applied to the inside and / or outside surface of the lamp bulb Coating reflecting IR radiation - hereinafter shortened as an IR layer designated - causes a large part of the radiated from the filament IR radiation power is reflected back on it.
  • the result achieved increase in lamp efficiency can be constant electrical power consumption for a temperature increase of the Luminous body and consequently an increase in luminous flux. on the other hand can be a predetermined luminous flux with lower electrical power consumption achieve - an advantageous "energy saving effect".
  • Another desirable effect is that due to the IR layer significantly less IR radiation power radiated through the lamp bulb and so that the environment, e.g. an optical projection device, less is heated than with conventional light bulbs.
  • the shape of the one provided with the IR layer Lamp bulb specially matched to the shape of the filament.
  • GB-A 2 082 383 discloses a lamp with an ellipsoidal bulb an annular filament is arranged in the circular focal line is. An IR layer is applied to the piston wall.
  • EP-A 0 470 496 discloses a lamp with a spherical bulb, in the center of which is a cylindrical filament. This font teaches that the loss of efficiency due to the deviation of the filament from the ideal spherical shape to an acceptable one under the following conditions Dimension can be limited. Either have piston diameters and filament diameter or length within a tolerance range be carefully coordinated, or the diameter of the Luminous body must be significantly smaller (small factor 0.05) than that of Lamp bulb. There is also a lamp with an ellipsoidal bulb specified, in the focal line an elongated filament axially arranged is.
  • the invention has for its object a light bulb with a flat core filament to be specified as a flat filament, characterized by an efficient Returning the emitted IR radiation to the luminous element and consequently, a high level of efficiency. Another aspect is that Distribution of the returned IR radiation on the filament. Moreover should enable compact lamp dimensions with high luminance are being striven for, especially for low-voltage halogen incandescent lamps becomes.
  • the invention proposes to specifically shape the lamp bulb so that the Lamp bulb with respect to lying in the light plane of the flat filament Axes has no rotational symmetry, but that the lamp bulb rather, a deviation from the rotational symmetry on the flat geometry of the filament, i.e. flattened shape having. If necessary, the shape of the base of the flat Luminous body on the actually irradiated by the reflected IR radiation Coordinate surface of the filament.
  • the invention proposes that the shape of the lamp bulb essentially corresponds to an ellipsoid with three semiaxes, of which are at least two different lengths and the filament is arranged within the lamp bulb such that the shortest of the three semiaxes of this ellipsoid perpendicular to the light plane of the filament is oriented. In this way, the lamp bulb receives with viewing direction in the light plane looks at the desired flat shape.
  • three sections are shown through an ellipsoid 1 with the three Semi-axes a, b and c.
  • the cuts correspond to the viewing directions in the three Cartesian spatial axes x, y and z, which are also collinear with the three Semi-axes a, b and c are selected.
  • the semiaxis c is shorter than the others two semiaxes a and b.
  • a stylized one flat filament 2 with two mutually parallel rectangular bases 3 or 3 'centered. These two base areas 3 and 3 ' correspond to those of a real flat filament Luminous surfaces that essentially generate the luminous flux of the lamp.
  • the luminous element 2 is now oriented within the ellipsoid 1 in such a way that its fictional light plane is perpendicular to the semiaxis c. So get lost the semiaxes a and b in the light plane and consequently parallel to the two base areas 3, 3 'of the luminous element 2.
  • the specific values for the three semi-axes are in the individual case on the shape and to specifically coordinate the dimensions of the filament, that the most efficient possible return of the emitted IR radiation the filament is reached.
  • the voting criteria for the three semi-axes also more towards a distribution that is as uniform as possible the returned IR radiation can be shifted on the filament.
  • local IR radiation power maxima so-called "hot spots” are usually detrimental to the long life of the filament and should therefore be avoided.
  • Improvement in distribution uniformity can also be achieved by a targeted adjustment of the outer shape of the filament to the shape of the retroreflective spot can be achieved on the filament. It has for example, it was found that, in the case of the maximum return of the emitted IR radiation, the retroreflective spot is substantially oval. For this reason, it can be advantageous for the filament as well choose an oval shape and also its outer dimensions to largely adapt those of the reflection spot.
  • Luminous bodies with a circular base and for lighting fixtures that are at least rough Approximation can be considered circular, e.g. Filament with square base, it can be advantageous to use the semiaxes a and b of the ellipsoid to be of equal length.
  • the targeted matching of the three ellipse half axes to the luminous element can be supported with so-called ray tracing methods.
  • there light rays emanating from the flat core helix are tracked and the Ellipse semi-axes determined such that maximum return efficiency or an optimal uniformity of the distribution of the returned Rays of light on the. Helix or whatever Compromise is achieved.

  • TiO 2 TiO 2
  • Ta 2 O 5 is also suitable.
  • the IR layer also covers about half of the pinch seal 7. In this way, a particularly dimensionally stable shape of the IR layer 9 is achieved, since when the lamp bulb 5 is manufactured, the outer surface of the calculated contour of the ellipsoid is embossed.
  • the individual layers in the region of the piston surface are particularly uniform. This reduces color errors.
  • the length of the lamp neck 6 is approximately 2 mm with a maximum width of approx.9.6 mm.

  • the luminous element 10 consists of a simple flat core filament (shown here only schematically, but see Figures 3a and 3b).
