Definitions
- the invention relates to a high-pressure discharge lamp according to the preamble of claim 1.
- Such lamps are in particular high-pressure discharge lamps for general lighting.
- the object of the present invention is to provide a high-pressure discharge lamp whose ignition is ensured by simple inexpensive means
- UV enhancers with two electrodes further components, such as a capacitor (US Pat. No. 4,987,344) or even more complex controls (US Pat. No. 4,721,888), are necessary in order to limit the current through the UV enhancer. Therefore, UV-enhancers have asserted that use only one electrode ha ben ⁇ and a dielectric barrier discharge. These UV enhancers are relatively cheap and can be contacted directly with sodium-free lamps or with discharge vessels without sodium diffusion (no additional components). The counterelectrode is brought from the outside to the vessel of the UV enhancer.
- the patents cited above contain examples of this. Possible are simple solutions, such as the application to the wire or more complex solutions such as a metalli ⁇ shear ring.
- a reliable ignition of two-sided HID lamps with two-sided discharge vessel made of quartz glass, in particular with sodium-containing filling, is characterized by a Capacitive coupling of the power supply for the dielectrically impeded UV enhancer possible.
- High-pressure discharge lamp having a starting aid, having a discharge vessel of ceramic or quartz glass, which is two ⁇ mutually locked, which is housed in an outer bulb, which is also two-sided striglos ⁇ sen, wherein the discharge vessel has two ends in which electrodes are attached, two of which
- UV enhancer is housed with a single electrode as an ignition aid in the outer bulb, characterized in that the UV enhancer sits in the vicinity of a second end of the discharge vessel, while a supply line from the first Stromzu ⁇ leadership starting along the discharge vessel leads ⁇ leads and thus the UV enhancer is connected, wherein the lead is capacitively coupled pazitiv with the first power supply, wherein the UV enhancer between
- High-pressure discharge lamp according to claim 1 characterized ge ⁇ indicates that the single electrode of the UV enhancer is capacitive coupled with the second power supply capacitive.
- High-pressure discharge lamp according to claim 1 characterized ge ⁇ indicates that the capacitive coupling between the lead and the first power supply by coaxial guidance of both conductors, semi-coaxial guidance, or is realized by parallel guidance of both conductors, or by flat expansion and parallel guidance of both Lei ⁇ ter.
- High-pressure discharge lamp according to claim 1 characterized denotes Ge, that the discharge vessel is made of ceramic, is ⁇ sinters with two capillaries at both ends, wherein the lead up to the two capillaries and the discharge vessel as a conductive line, wherein the capacitive coupling to each - Because running in the capillary running takes place.
- High-pressure discharge lamps according to claim 4 characterized in that extending from the line a conductor in the direction of UV enhancer.
- High-pressure discharge lamp according to claim 4 characterized ge ⁇ indicates that an additional coupling capacitor between the bar and the first supply line is introduced.
- High-pressure discharge lamp according to claim 4 characterized ge ⁇ indicates that the dielectrically contacted end of the UV enhancer is mounted in the immediate vicinity of the line on the second capillary.
- High-pressure discharge lamp according to claim 1 characterized ge ⁇ indicates that the discharge vessel has a sodium-containing filling.
- High-pressure discharge lamp according to claim 1 characterized in that the discharge vessel is made of quartz glass ⁇ .
- Fig. 1 is a high-pressure discharge lamp with ignition aid, according to
- FIG. 1 schematically shows a metal halide lamp 9, in which a quartz glass discharge vessel 1 is contained in an outer bulb 2 made of quartz glass. Both vessels are cylindrical vessels closed on two sides.
- a first power supply line 3 is sealed in both a first end 4 of the outer envelope and in a first end 14 of the discharge vessel and leads to an ers ⁇ th electrode 5 in the discharge vessel 1.
- a second current ⁇ feed 6 is both in the second end 7 of the Outer piston and sealed in a second end 15 of the discharge ⁇ vessel and leads to a second electrode 8 in the discharge vessel.
- a supply line 10 goes along the discharge vessel to the level of the second power supply 6. There it ends at the single electrode 11 of a UV enhancer 12. This is coupled to the second power supply 6 dielectrically.
- FIG. 2 shows the structure of a metal halide lamp 20 according to the invention in a highly schematic manner. It has a discharge vessel 21 made of quartz glass, which is housed in a réellekol ⁇ ben 22 made of quartz glass.
- the structure differs from the state of the art because it can not lead to sodium leakage.
- the reason is that the feed line 23 leading past the discharge vessel is only capacitively coupled via the capacitor 24 and not galvanically as in FIG.
- the entire, formed by the supply line 23 power supply for the UV enhancer 25 is galvanically decoupled and can not as in the ⁇ known solution using a ceramic tube still partially cause photoemission and sodium leakage.
- the contacting of the single electrode 26 of the UV-enhancer may be oriented in both directions so ⁇ well aligned with the electrode towards the capacitive ge ⁇ coupled lead 23 ( Figure 2) and oriented towards the feed line 23 (see FIG. 3).
- the second electrode of the UV enhancer is dielectrically coupled to the respective supply line or power supply, symbolized by reference number 27.
- both types of contacting for the single electrode of the UV enhancer 25 are always meant, even if only one form is shown.
- FIG. 4 shows another embodiment, in addition to the circuit of Figure 3, the electrode 26 of UV-enhancer 25 also capacitively coupled through a further capacity Ka ⁇ 30 to the second power supply.
- the capacitive coupling may in particular by means dis ⁇ cretan components such as a capacitor.
- Other forms of capacitive coupling are also possible by clever geometric arrangement of the conductors / contacts (eg parallel or coaxial guidance possibly with suitable dielectrics). Some examples of this are shown in FIG.
- the choice of dielectrics is limited because of the possible high temperature load. Here are materials made of glass and ceramic possible. Examples of cross sections of different geometries for the realization of a capacitive coupling are possible.
- Figure 5a shows a coaxial arrangement of the first power supply 3 and supply line 10 for the realization of the capacitive coupling 24.
- Figure 5b shows a coaxial arrangement of the first power supply 3 and supply line 10 for the realization of the capacitive coupling 24, the power supply 3 from the supply line 10 only half is enclosed.
- FIG. 5c shows a simple parallel guidance of first power supply 3 and supply line 10.
- FIG. 5 d shows a simple parallel guidance of ers ⁇ ter power supply 3 and supply line 10, wherein both are at least partially performed as a sheet-like foils, so that a particularly intensive capacitive coupling is possible borrowed.
- a galvanically decoupled feed line 40 is sintered onto a ceramic discharge vessel 30.
- a capacitive coupling takes place by the parallel guidance of the sintered supply line 40 on a first capillary 31 with the first power supply 3, or a feedthrough 43 attached thereto to the discharge vessel in the capillary 31.
- the sintered supply line 40 is sufficient to the other side of the discharge vessel, where a second capillary 41 is mounted, where also the UV enhancer 25 is ⁇ introduced . From this feed line, a contact 35 is led to the UV enhancer 25.
- the installation of the UV enhancer is again similar to that in Figure 2 or 3.
- Figure 7 shows an embodiment similar to Figure 6 with an additional capacitance 45 to enhance the capacitive coupling.
- the sintered-on feed line 40 is used directly as an external, dielectrically impeded electrode for the UV enhancer 25.
- the geometric arrangement must be such that the sintered section at the end of Feed line 40 comes as close as possible to the enveloping vessel of the UV enhancer. In this way, no separate contacting of the sintered supply line as in Figure 7 is necessary.
- the particular advantage of the new arrangement is that ignition is achieved without time delay.
- the sodium outlet of the discharge vessel is prevented by a capaci tive ⁇ coupling of the supply line that leads to the discharge vessel by a cost-effective manner.
