Definitions
- the invention is based on a compact low-pressure discharge lamp the preamble of claim 1. It is in particular a compact Low-pressure discharge lamp with a discharge vessel of at least four straight, parallel tubes arranged in a polygon and through Cross-connections at or near the ends of the straight tubes to form a single coherent and gas-tight sealed discharge path are connected.
- the compact low-pressure discharge lamps with one of four or more straight existing parallel pipes and assembled by cross connections Discharge vessel depending on the length and diameter of the Discharge vessel and the inner diameter of the cross connections, often very high Tensions to be able to ignite safely.
- the object of the invention is therefore a compact low-pressure discharge lamp lowering the ignition voltage to create that inward from the degrees Tubes and the cross connections of the discharge vessel cavity formed emitted light can pass largely unhindered.
- a metal coil spring keeps the space inside the straight tubes of the discharge vessel largely free. This allows most of the in the central cavity between the straight tubes of the discharge vessel Radiation can pass unhindered or after single or multiple reflection at the Discharge vessel walls come out again. In addition, the temperature balance the low-pressure discharge lamp is only slightly influenced.
- the coil spring can have a reflective coating exhibit. This allows the discharge into the center of the discharge vessel and radiation that strikes the coil spring partially outwards again radiate so that the radiation loss caused by the insertion of the coil spring is further reduced.
- the coating preferably has a reflectance, which corresponds to that of the fluorescent-coated discharge vessel.
- the coil spring is advantageously made of wire, with a wire diameter between 0.05 and 1 mm, depending on the amount of ignition voltage reduction required is chosen.
- the amount of ignition voltage reduction can be determined by the number of the Walls of the straight tubes of the discharge vessel adjacent turns Adjust coil spring. All that is required is the diameter of the Number of turns of the coil spring that are to be in contact with the discharge vessel, to adapt to the diameter of the cavity.
- the slope factor SF i. H. the ratio of the distance between two neighboring ones Wire turns to the diameter of the wire, determines the number of wire turns, which has a coil spring of a certain length.
- the number the turns of the coil spring can in turn be the value of the reduction in Ignition voltage can be set.
- the coil spring has a pitch factor SF of 1.5 ⁇ SF ⁇ 70.
- the coil spring preferably has an initial length in the relaxed state, that between the one and five times the distance of the cross-connections remote from the base housing of the discharge vessel from the end facing the discharge vessel of the base housing.
- it preferably has at least the base housing last turn or the last turns of the coil spring have one such a diameter that they lie against all walls of the straight pipes.
- the lamp 1 shown in FIGS. 1 and 2 has a power consumption of 42 W.
- the three sections 3, 4, 5 are - in plan view - arranged in a triangle and close a base housing 9 made of plastic via cross connections in the form of cross fusions 10, 11 also connected to each other from glass.
- the free ends the straight tubes 6, 7 of the three sections 3, 4, 5 are gas-tight (not visible here) sealed and held in the base housing 9.
- the Base housing 9 carries at its end facing away from the discharge vessel 2 Contact system 12 in the form of a base of the type GX24q-3.
- the coil spring 14 In the cavity formed by the three sections 3, 4, 5 of the discharge vessel 2 13, a coil spring 14 is inserted.
- the coil spring 14 consists of Spring steel with a wire diameter of 0.5 mm.
- the coil spring 14 is in the lamp 1 between the upper end wall of the base housing 9 and the Base housing 9 facing outer wall of the 180 ° bends 8 clamped and lies with all of its turns on the straight tubes 6, 7 of the discharge vessel 2 on. When clamped, it has a winding spacing of 5 mm and thus a slope factor SF of 10.
- the length of the clamped coil spring 14 measures 93 mm and has an outer diameter of 15.4 mm.
- the luminous efficiency is reduced when using a hollow cylinder from an uncoated aluminum foil of the same length and the same Diameter like the coil spring 14 by more than 10%.
