Definitions
- the invention relates to a filament for a lamp. This is what it is about is in particular a discharge lamp filament, which is under high internal pressure and works on the gas discharge principle.
- Luminous bodies of the type mentioned are in widespread use today Application. An important area of application is lamps for automobiles, for example their headlights. A common area of application are Shops in which the illuminants mentioned are used, in combination with reflectors. Other areas of application are Video projection systems and stage lighting spotlights.
- Such luminous bodies comprise a hollow glass body, furthermore two therein enclosed electrodes made of metal.
- the energy supplied to the filament is only partly in light implemented. A significant portion is released to the environment in the form of heat submitted. This is highly undesirable for two reasons: one is the amount of energy converted into heat for the generation of light not available.
- components are heated that the Luminous body surround, and which are affected by the heating. To reduce or avoid the adverse effects of heating, special measures must be taken. So must for example, the surrounding parts of a lamp are sufficiently large Have a distance from the filament, be dimensioned accordingly that they withstand thermal stresses or are cooled. All these Measures require additional effort, which the manufacturing costs of Systems enlarged.
- Halogen lamps of the type mentioned with infrared reflectors are known Coating. With this one pursues the goal from which Luminous energy supplied as much light energy as possible through back reflection to get the infrared radiation out on the helix. This However, the principle only works with temperature radiators such as Blackbody emitters, but not with arc lamps or Discharge lamps.
- the invention has for its object a lamp to create mentioned type, which is designed such that the disadvantageous Effects of the amount of heat generated during operation take priority to prevent or at least reduce, and possibly also the Increase luminous efficacy and influence the spectral distribution.
- the inventors have followed a new path.
- the amount of heat given off by the filament to the outside greatly reduced.
- the reduction can reach such a level that additional measures such as cooling, special dimensioning of the surrounding components of the associated lamp or compliance with a especially large distance of such components from the filament is unnecessary become.
- the advantageous practical effects of the invention are for example, the following:
- the surrounding components do not have to necessarily be made of glass, as in the prior art. Suitable Plastics can be used.
- the invention has a particularly advantageous effect in headlights for projectors in which those with strong Noise-related ventilation throttled or completely avoided can be. There are possible uses of lighting fixtures mentioned type, which was not previously due to the heat development were given.
- a dielectric layer package is particularly suitable as a filter layer.
- Material pairings such as the following are suitable: SiO 2 -TiO 2 SiO 2 -Nb 2 O 5 SiO 2 -Ta 2 O 5 .
- PICVD Pulsma Impulse Chemical Vapor Deposition
