Definitions
- the invention proceeds from a high-pressure discharge lamp according to the preamble of claim 1.
- These are in particular ⁇ sondere high pressure discharge lamps having a ceramic discharge vessel and metal halide.
- Prior Art From DE 102007015483 and WO 2006/081804 is a re ⁇ flektorlampe known that uses a built-in lamp, ba ⁇ sierend on a ceramic discharge vessel with metal ⁇ halogenid Collllung. These are anchored extra in the reflector with tools, for example by using potting compounds, such as silicone resins or Sockkitt. An alternative is to use double capped lamps.
- the outer bulb is either left constant in the diameter or rather narrowed, see DE19913297.
- An object of the present invention is to provide a high pressure discharge lamp which can be mounted in a simple and Re ⁇ Flektor electrically especially effet fürschlägstest. This object is solved by the characterizing features ⁇ times of claim 1. Particularly advantageous embodiments can be found in the dependent claims.
- the problem is solved by an outer bulb design, which consists of two differently sized piston sections.
- the diameter d2 of the upper outer piston tube portion has an optimization criterion which differs from the optimization criterion of the lower outer piston tube portion un ⁇ .
- the diameter d2 should be as small as possible in relation to d3, where d3 represents the diameter of the discharge vessel.
- d3 represents the diameter of the discharge vessel.
- the length h 2 of the lower, widened outer bulb tube section is preferably smaller than the distance between the center of the discharge vessel and the lower outer bulb tube edge h 1.
- a possible ⁇ lichst small length applies h2.
- the Behaves ⁇ nis of h2 / hl should be ⁇ 0.6.
- the closure technology of the evacuated outer bulb can be selected as usual in conventional high-pressure discharge lamps, in particular squeezing in the lower region, pulling off and fusing the pump stem in the upper region.
- the outer bulb is in particular made of tempered glass, but quartz glass is preferred.
- the quartz glass may be used for effective UV protection with additives, e.g. Cer, be doped, as is well known.
- the generation of the bottle neck shape can be done in various ways, in particular, the following execution examples ⁇ advantageous:
- An outer piston starting tube consisting of a tube section with a diameter d2 and a domjan be ⁇ fused exhaust tube is heated and expanded by means of a mold at the bottom tube section to the diam ⁇ ser dl according to the length h2. Subsequently ⁇ td is the frame with the burner in the outer bulb introduced and squeezed in the lower, expanded area of the outer bulb with heat.
- the lamp preferably uses a ceramic discharge ⁇ vessel, which is housed in an outer bulb.
- basic ⁇ additionally can also be a different kind of high-pressure discharge lamp, the inner vessel.
- Advantages of the new design are in particular:
- the lower, flared outer tube section allows the use of power supply wires having such a large distance from each other that electrical breakdowns in air atmosphere at high ignition voltages, eg. B. at> 10 kV, can not take place.
- high ignition voltages eg. B. at> 10 kV
- the upper, narrowed outer tube section allows the use of the lamp in reflectors, which have only a very small reflector neck opening. This has the purpose of gaining as much useful light, and to lose little light in the direction of the reflector neck.
- the volume of the outer bulb can be very small, provided that d2 and h2 are very small. As a result, the lamp reaches a thermally stable operating state faster after switching.
- FIG. 1 shows a lamp with a ceramic discharge vessel in an outer bulb
- FIG. 2 is a bottom view of the lamp of Figure 1;
- FIG. 3 shows a reflector lamp with such a lamp;
- FIG. 4 shows a blank for the outer bulb
- FIG. 5 shows a further embodiment of a blank
- Figure 6 shows another embodiment of a lamp; 7 shows a view from below of the lamp from FIG. 6.
- a metal halide lamp 10 is shown. It is, for example, a 150 W lamp with a ceramic discharge vessel 1. It is used in particular as a built-in lamp.
- the discharge vessel 1 is made up of a bulbous With ⁇ telteil 2 and two end sections 3, 4 together.
- the end section 3, 4 is in each case closed by a capillary technique, as known per se.
- the discharge vessel made of ceramic is housed by means of a Ge ⁇ stells 6 with short and long power supply 7, 8 in an outer bulb 9 made of glass, generally tempered glass or quartz glass.
- the outer bulb is divided into two parts.
- a first section 11 is cylindrical with an outer diameter d 1, on which sits a second section 12, which is likewise cylindrical, but with a reduced diameter. decorated outer diameter d2.
- the axial length of the second portion is sized so advantageous that it is with ⁇ telteil 2 of the discharge vessel accommodated completely in the second section 12th
- the maximum outer diameter of the discharge vessel is denoted d3.
- the basic relationship d3 ⁇ d2 ⁇ dl applies here.
- the three diameters each differ by at least 10%.
- Hl is the height of the center of gravity, ie the center of the discharge arc, which is important for the position in a reflector.
- h2 denotes the length of the lower portion of the outer bulb.
- the outer bulb is provided at its upper end with a pump tip 16. The outer bulb is evacuated.
- FIG. 2 shows a plan view from below of the lamp of FIG. 1.
- FIG. 3 shows a reflector lamp 20.
- This uses the lamp 10 as described above built-in lamp, wherein a Re ⁇ Flektor 21 having a contour 22 and a neck is mades- tattet 23rd The neck sits in the area of the second abdomen. Section on the lamp 10.
- the contour 22 is here in particular ⁇ so extended in the direction of the outer bulb 9 (24), that it fits tightly against it, so that the amount of light is optimally collected by the contour.
- the production of the novel outer bulb succeeds in various ways.
- FIG. 4 An original blank 30 is heated with a constant diameter d2 at its lower end 31 and then widened.
- An alternative is shown in FIG.
