Definitions
- the invention relates to a high-pressure discharge lamp ge ⁇ Mäss the patent claim. 1
- Such high-pressure discharge lamps for example halide metal halide lamps and high-pressure mercury lamps, are offered by OSRAM GmbH under the lamp family designation VIP® and P-VIP and used, for example, in the field of multimedia data and video projection.
- VIP® and P-VIP lamp family designation
- a corresponding lamp construction is also described in DE 10 2005 017 505 A1.
- These known high-pressure discharge lamps have a burner are provided with a discharge vessel in which two diametrically mutually ⁇ arranged shafts. In the discharge vessel, two electrodes are arranged, which are connected to power supply lines by means of sealing foils melted into the shafts.
- an ignition aid may be provided which engages around a portion of a shaft with auxiliary ignition bubble and cooperates with one of the electrodes, so that when a potential difference is applied, the ignition process is assisted.
- the burner is held by means of a bonding compound, hereinafter referred to as putty, on a laterally partially open ceramic.
- This ignition aid can either at the front in the beam direction of the burner shaft or on the ceramic side rear shaft be arranged.
- the latter alternative has the advantage that the luminous efficacy is slightly increased in relation to an ignition aid arranged in the front burner region.
- the object of the present invention is to provide a high-pressure discharge lamp, in which the device protection and the ignition behavior are improved with low device complexity.
- a high-pressure discharge lamp with a burner having a discharge vessel and two has at this coaxially arranged shafts and in the two spaced apart electrodes are taken up ⁇ . These are connected to the shaftsssenschmol ⁇ zene sealing foils with current supply leads, WO surrounds the portion of a sheep ⁇ tes with Zündosblase at an auxiliary ignition device, and with one of the Elect ⁇ clear for improving the ignition behavior cooperates.
- the burner is held by means of a bonding compound to a ceramic.
- the ignition aid is arranged in the ceramic as splinter protection.
- the auxiliary ignition device thus has a dual function, since on the one hand it improves the ignition behavior and on the other acts as splinter protection.
- the structural complexity for realizing the high-pressure discharge lamp can be substantially reduced compared to conventional solutions, in which the Zündoseinrich- device and the splinter protection is always ensured by independently acting devices.
- the light output can be increased compared to solutions in which the ignition aid is located in the front burner area.
- the high-pressure discharge lamp is designed as a reflector lamp, wherein the reflector is also held on the ceramic.
- the contacting of the Zündos beautiful can be done for example via a Zündisdraht, which is connected to one of the power supply lines.
- the power supply can be placed, for example, to the front in the emission direction burner side so that it leads past the ignition aid, so that a di ⁇ direct contacting can be done with this power supply.
- the power supply is then guided axially through the reflector.
- the power supply can be guided laterally through the reflector, in which case said Zündisdraht should be required for contacting.
- the grid-shaped ignition aid is preferably used with a certain bias in a through hole of the ceramic.
- the grid is approximately cylinder jacket-shaped.
- the high-pressure discharge lamp is preferably designed as a high-pressure mercury lamp or metal halide lamp. In principle, however, other Lampenty ⁇ pen with acting as splinter protection Zündosvoriques are executable.
- Figure 1 is a schematic longitudinal section through a high-pressure discharge lamp according to the invention
- Figure 2 shows a portion of the high pressure discharge lamp of Figure 1 in an enlarged view
- FIGS. 1 and 2 shows a three-dimensional representation of a ceramic of the high-pressure discharge lamp according to FIGS. 1 and 2.
- FIG. 1 shows a simplified longitudinal section through an embodiment of a high-pressure discharge lamp 1.
- This is designed as a reflector lamp and has a burner 2, which is used together with a reflector 4 in a ceramic 6.
- the reflector 4 consists in ⁇ example of glass and is provided with a reflective coating.
- a front panel or front cover can be used, so that the environment is protected in a burner explosion forward.
- the burner 2 consists essentially of an approximately centrally arranged discharge vessel 10, on which two arranged in the axis of the reflector 4 shafts 12, 14 are arranged.
- tungsten ⁇ be stationary electrodes 16, 18 which via the shafts 12, 14 melted sealing films 20, 22 made of molybdenum with power leads 24 are contacted 26th
- the power supply 24 associated with the front shaft 12 is guided laterally through a sealed bore of the reflector 4.
- the power supply associated with the rear shaft 14 Guide 26 extends axially through the ceramic 6 therethrough. In principle it is also possible to lead the front check power supply ⁇ tion 24 along the burner 2 through the ceramic 6 therethrough.
- the discharge vessel 10 can be filled at a high-pressure discharge lamp with a filling with proportions from Quecksil ⁇ over, metal halides, rare earth and a rare gas mixture, so that the discharge arc between the two electrodes 16, 18, high pressure in an atmosphere of halogen and mercury vapor and burning. It can also be a high-pressure mercury lamp.
- the bubble 28 passing through the sealing film 22 is then approximately the same potential difference, as between the two electrodes 18, 22.
- a commercial electronic ballast electronic ballast
- the grid was brought to 30 Zündosblase 28 to the same potential as the sealing film 22 in the shaft 14 - in this case, the ignition ⁇ helpful bubble 28 is illuminated when the ignition of the high-pressure discharge not pe.
- a base 35 is provided, from which the power supply 26 extends.
- FIG. 3 shows a three-dimensional representation of the ceramic 6, in which the grid 30 is inserted.
- This is formed from a rectangular grid strip whose elongated length is slightly shorter than the circumference of a through hole 34 of the ceramic 6.
- the grid 30 can be held in the through-hole 34 due to its spring action. In principle, however, it is also possible to fix the grid 30 by suitable measures, for example by putty or the like.
- the ceramic 6 shown in FIG. 3 is a standard component which can also be used in conventional discharge lamps in which the grid 30 is not provided. Because the basic structure in itself is known, only a few essential elements of the ceramic 6 will be described.
- the ceramic 6 is cut freely between the two circular segment sections 36, 38 by wedge-shaped cutouts 56, 58, so that corresponding circumferential sections 52, 54 of the grid 30 are exposed. These sections extend in the illustration according to FIG. 2 above and below the plane of the drawing and are therefore not visible.
- the grid 30 in the comparatively large radial ⁇ distance to the burner 2 or more specifically to the adjacent shaft is arranged so that the periphery is increased entspre ⁇ accordingly.
- the Ke ⁇ ramik 6 described with reference to Figure 3 can be used for lamps with splitter guard and without splinter guard, so that the production and storage are possible with minimal effort.
- a high-pressure discharge lamp with a burner which is provided to improve the ignition with a Zündanges adopted.
- This is inventively formed as a grid, which surrounds the burner in the region ei ⁇ ner ceramic holding the burner and is contacted with one of the power supply lines.
- the ⁇ ses grid acts as an ignition aid and as splinter protection in a burner explosion.
