Definitions
- the invention relates to a halogen incandescent lamp which essentially comprises a lamp bulb, a dimming cap, three retaining pins and two incandescent filaments, wherein the interior of the lamp bulb filled with a halogen-containing gas and at least one retaining pin is welded to the Abblendkappe.
- Halogen incandescent lamps produce visible light by heating a tungsten filament usually by direct current passage to temperatures in the range of 2300 ° C to 3200 ° C.
- the filling gas contains iodine, bromine or chlorine, which are among the halogens, alone or in combination with halogenated hydrocarbons.
- CVT chemical vapor transport
- Oxygen is also introduced into the lamp via the components of the lamp frame, wherein the oxygen may be present in superficially adsorbed, dissolved or bound form. Especially differences in superficially adsorbed oxygen have a significant influence on the service life of the halogen incandescent lamp. Especially with lamps whose components of the lamp frame have a high surface area, differences in the specific oxygen concentration at the surface trigger serious fluctuations in the service life behavior.
- Halogen bulbs with anti-dazzle device are used in motor vehicle headlamps. These halogen lamps are commonly referred to as H4 lamps.
- the dimming cap is located in the interior of the lamp bulb, which also contains two filaments and three retaining pins.
- An incandescent filament is arranged in the region of the dimming cap.
- the dimming cap limits the light beam, which prevents glare. This filament is referred to as Abblend mindfull.
- the second filament is outside the range of the dimming cap and produces the high beam. This filament is called Aufblend Maisl.
- the dipped beam is connected to the dimming cap and to a molybdenum retaining pin. Resistance welding is usually used as the joining method, wherein a sleeve made of molybdenum is placed in the connection region of the incandescent filament in order to make the joining zone more stable.
- the anti-dazzle device can have a welding lug which serves for welding to one end of the anti-dazzle coil, as described in German patent specification DD 2 24445.
- This sweat lug may in turn be provided with a transverse rib which serves to hump weld to one end of the Abblend Maisl.
- the bottom of the dimming is usually flat and provided with two Sch paswülsten, which usually also allow a projection welding with the molybdenum retaining pin.
- As material for the dimming cap only pure molybdenum has hitherto been used, since it was assumed that alloying elements influence the constancy of the halogen cycle process. In particular, ODS (oxide dispersion strenghtened) molybdenum materials have not been used because of their higher oxygen contents and their mostly halide-forming alloying elements.
- Cost pressure stands so that the market only accepts solutions that are cost-neutral or cost-cutting.
- the aim of the invention is therefore to provide a halogen lamp with anti-dazzle device available, which has a very constant and long life, with the lowest possible cost.
- a further object is to provide a Abblendkappe available that leads to the least possible extent to lifetime variations of halogen lamps and further reduce the cost of this dimming compared to existing solutions.
- Abblendkappen consisting of a molybdenum alloy containing 0.1 to 1, 5 wt.% Yttriumoxid and / or one or more oxides of lanthanides, a much more constant and improved service life of H4 lamps can be achieved. This is also shown by the analysis values of incandescent filaments taken from H4 lamps that have failed due to hot-spot formation of the filament.
- Incandescent filaments show a fluctuating molybdenum value when using pure molybdenum screening caps. If one now converts this integral value to a hypothetical thickness of a deposited Mo layer, layer thicknesses of 0.03 to 0.55 ⁇ m result when using pure molybdenum screening caps.
- Abblendkappen which consists of a
- Molybdenum alloy consisting of 0.1 to 1, 5 wt.% Yttria and / or one or more oxides of lanthanides, significantly more constant values can be achieved, as can be seen from Table 1. Since in lamp production according to the examples only the material of the dimming cap was varied, it can be assumed that the reduction in the variance of the molybdenum deposit can be attributed to the use of the dimming cap according to the invention. Since the molybdenum separation in turn depends primarily only on the oxygen or water vapor content of the filling gas, it can be assumed that this is more constant in the case of dimming caps according to the invention.
- the dimming cap exerts a dominant influence here can be explained by the fact that the dimming cap is the metallic component with the largest surface area.
- the dimming cap is the metallic component with the largest surface area.
- For the lamp manufacturer are the absolute values of the introduced Oxygen or water vapor of little importance, since they can be adjusted by appropriate Zudotieren. If, on the other hand, different levels of oxygen or water vapor, which originate from the dimming cap, can not be corrected during lamp production.
- a particularly low variance of the Mo deposition can be achieved when using Y 2 O 3 and Y 2 O 3 x Ce 2 O 3 doped materials.
- the optimum oxide content is 0.3 to 1.0% by weight.
- Substantial improvements could also be achieved with materials doped with La 2 O 3 , although it should be noted that with contents> 0.5% by weight, the tendency for piston blackening increases.
- FIG. 1 shows an H4 lamp with a tempered glass lamp bulb.
- FIG. 2 shows a dimming cap with welded molybdenum retaining pin.
- Table 1 shows the hypothetical strength of the molybdenum layer on the
- Table 2 shows the required peel force to remove the retaining pin from the
- H4 lamp -1- (see Figure 1) was made according to the prior art, wherein the lamp bulb -2- was performed in toughened glass.
- the lamp frame consisted of a Abblendkappe -3-, in Figure 2 in detail is shown.
- a molybdenum holding pin -A- was welded to the two bumping beads -9- and the dipping spiral -5- via a sleeve by means of resistance welding to the transverse rib -8- of the welding flag.
- the Aufblend mindfull -5- again with sleeve welded to the aforementioned retaining pin -A-.
- the anti-dazzle device For the preparation of the anti-dazzle device, different oxides of the group yttrium, lanthanide-containing, molybdenum alloys were used, as shown in Table 1. Starting with strips 0.10 mm thick, the dimming caps were produced by a stamping / stamping process. In comparison to this, pure molybdenum screening caps were manufactured, which were made of a band with a thickness of 0.13 mm. From each type of material 10 lamps were manufactured and continuously tested under standard conditions for 1000 h. After that, the
- Destroys lamps determines the molybdenum content of the filament and calculates a hypothetical Mo layer thickness. These values are shown in Table 1. It can be seen from this that the scattering range for lamps with pure molybdenum dimming cap is significantly greater than is the case with lamps with dimming caps according to the invention.
- test pieces were made by only one molybdenum holding pin with a diameter of 0.6 mm was connected to the Abblendkappe corresponding to the component of Figure 2 by means of resistance welding. Thereafter, the strength of the welded joint of 10 samples was determined by a peel test in the tensile test and the average value was calculated. From Table 2 it can be seen that the components with the Abblendkappen invention at a wall thickness in the bottom of the 0.10 mm anti-dazzle cap similar to the weld strength of pure molybdenum anti-dazzle caps with a wall thickness of 0.13 mm.
