Definitions

  • the present invention relates to a lighting arrangement which consists of an elongated gas discharge lamp and a shielding sleeve provided for the gas discharge lamp.
  • the present invention relates to a shielding sleeve for a low-pressure discharge lamp.
  • the temperature of the lamps must be within a predetermined range.
  • the so-called T16 lamps which are named after the fact that their tube has a diameter of 16mm, the optimum temperature range is 40-44 ° C.
  • T16 lamps mentioned above unlike the likewise known T26 lamps with a broader lamp diameter, have different lengths of feed lines to the lamp electrodes.
  • This asymmetric configuration of a T16 lamp with regard to its electrodes means that in these lamps the cool spot comes to rest at the end at which the longer electrode feed line is placed, or at which the distance of the electrode to the front end of the lamp is greater ,
  • the cool spot in the symmetrically designed T26 lamps is always in the middle of the lamp.
  • T16 lamps are more temperature sensitive than T26 lamps.
  • fluorescent lamps in particular the above-mentioned T16 lamps used in air conditioning lights, ie in lights that have supply or exhaust openings in the lamp housing, which are connected to an air conditioner, so the constantly existing draft causes these lamps cool down, ie the cool spot has a temperature that is well below 40 ° C.
  • the lamp cools down to such an extent that a temperature well below 40 ° C is present at the Cool Spot.
  • this cooling has the consequence that the efficiency of the lamp is no longer optimal.
  • a luminaire for fluorescent lamps with a protective tube in which a heat compensation sleeve made of copper is mounted in the region of the lamp electrodes.
  • the US 4,629,929 describes a quartz glass sleeve which is intended to radiate heat radiation back into the electrode region of a discharge lamp.
  • the present invention is therefore based on the object to improve the known shielding tubes for fluorescent lamps so that with them even at low ambient temperatures of the cool spot are kept in an optimal temperature range and thus the lamp can achieve a sufficiently high luminous flux.
  • the object is achieved by a lighting arrangement according to claims 1 or 2 or by a shielding sleeve for use in a gas discharge lamp according to one of the two claims 13 and 14.
  • the shielding sleeve in such a way that it at least partially has a layer of a good heat-conductive material whose thermal conductivity is greater than or equal to 30 W / mK.
  • the shielding sleeve at least partially has a reflective layer.
  • the shielding sleeve is designed such that it has both properties - ie both a good thermal conductivity and the ability to reflect electromagnetic radiation - which can be achieved, for example, by the shielding sleeve having at least partially a corresponding metal or aluminum layer.
  • both of the above-mentioned properties contribute to an optimized temperature shielding of the lamp compared to the one described above Environment.
  • the reflective property of the shielding sleeve causes the heat generated at the lamp filament or lamp electrode, which is emitted as heat radiation, to be reflected back again and thus fed back to the lamp.
  • a high thermal conductivity shielding sleeve helps to increase the temperature in the adjacent area of the lamp's cool spot to the area of the cool spot. In other words, the shielding sleeve itself is heated and transfers this heat in a desired manner to the lamp in the area of the cool spot.
  • the shielding sleeve should thus have a high thermal conductivity, which should be at least in the range of the heat conductivity of metals.
  • the thermal conductivity of lead is called, which is about 35 W / mK.
  • the material used should therefore have a thermal conductivity of greater than or equal to 30 W / mK.
  • the preferably used aluminum even has a conductivity of 220 W / mK.
  • the sleeve consists of a - preferably transparent - existing plastic base body, which is at least over a part of its length or even over the entire length of time covered with a layer of a reflective and / or thermally conductive material.
  • a reflective and / or thermally conductive material there is also the possibility (not claimed) of forming the shielding sleeve completely from the thermally conductive and / or reflective material.
  • Optimal results were obtained with an aluminum sleeve, which has a wall thickness of about 1mm and - depending on the ambient temperature - about 35-50mm long.
  • the shielding sleeve obtained in this way is then arranged at the front end of the gas discharge lamp, on which the cool spot is located. As already mentioned, in the T16 lamps this is the end where the lamp electrode with the longer electrical leads is located.
  • the shielding sleeve can be arranged such that it surrounds the electrical leads, but not the lamp electrode itself. As a result, despite the - when using metal - opaque shielding a sufficiently high luminous flux is achieved. At particularly low ambient temperatures, however, sleeves can also be used, which completely surround the electrode due to their length.
  • the shielding sleeve according to the invention is preferably intended for use with low-pressure discharge lamps, in particular for use in the T16 lamps described above.
  • the in the Fig. 1a and 1b Lighting arrangement shown consists of a cylinder-like elongated gas discharge lamp 1 and a pushed onto a front end of the lamp 1 shielding 10.
  • the illustrated lamp 1 is a low-pressure discharge lamp, in particular a T16 lamp whose lamp body 4 has a diameter of 16 mm.
  • a particular feature of the illustrated T16 lamp 1 is that the electrical leads 3a and 3b are of different lengths for the two lamp electrodes 2a and 2b.
  • the lead 3a is longer for the lamp electrode 2a arranged on the left side, with the result that the electrode 2a is farther away from the corresponding front end of the lamp 1 than the electrode 2b.
  • the cool spot of the lamp 1 that is to say the region at which the lamp 1 has its lowest temperature during normal operation, is arranged at the left end of the lamp 1.
  • the shielding sleeve 10 In order to prevent cooling of the lamp 1 in the region of the cool spot to a temperature below 40 ° C., in particular at low ambient temperatures, the shielding sleeve 10 according to the invention is pushed onto the left front end of the lamp 1.
  • the shielding sleeve 10 is made entirely of aluminum.
  • the shielding sleeve 10 is so in relation to the Lamp 1 is arranged so that it surrounds the leads 3a for the lamp electrode 2a, but not the electrode 2a itself. This ensures that the output from the lamp 1 luminous flux is not affected by the opaque aluminum.
  • the aluminum surrounding the electrical leads 3a of the shielding sleeve 10 has the consequence that the heat generated at the electrode 2a is reflected and the lamp 1 is additionally heated in the forehead area. This ensures that the lamp 1 can be operated even at ambient temperatures below 25 ° C even at optimum temperatures.
  • the left end of the lamp 1, where the cool spot is located, is thus heated by the shielding sleeve 10 so far that it can be maintained in the required for optimum lamp operation temperature range of 40-44 ° C despite the low ambient temperatures.
  • the length of the shielding sleeve 10 determines the degree of achievable temperature increase. There is thus the possibility, by selecting the length of the shielding sleeve 10, to set different ambient temperature ranges at which the shielding sleeve 10 achieves the suitable effects. In other words, different lengths of shielding sleeves 10 can be provided, each sleeve being optimal for a different ambient temperature range.
  • a shielding sleeve 10 made of aluminum has a length of about 35-50 mm, wherein the area which is pushed over the base, about 10mm long and the area surrounding the glass bulb 4 about 25-40mm, in particular 30-35 mm long.
  • the wall thickness of the glass piston 4 enclosing portion of the sleeve 10 is between 0.5mm and 2mm, preferably at about 1mm. It has been found that with an aluminum sleeve, which has a wall thickness of 1 mm and a total length of 40 mm, the temperature at which the lamp can be operated under optimum conditions can be reduced by about 15 °.
  • FIGS. 2 and 3 show the shielding sleeve 10 in a side view or in front view. This points - as in Fig. 2 is shown - one of the shape of the lamp corresponding inner contour, so that it can be placed in register on the front end of the lamp.
  • the shielding sleeve 10 in the present case is made entirely of aluminum, since contrary to the original assumption that such an aluminum sleeve has a cooling effect, it has surprisingly been found that even very good results are achieved with a shielding sleeve made entirely of aluminum can. This is attributed to the fact that the aluminum sleeve not only reflects back the heat generated at the lamp electrode, but additionally heats up and transfers the heat in the desired manner to the lamp in the area of the cool spot.
  • the shielding sleeve is formed from a base body made of - preferably transparent - plastic, the inside of which is coated with an aluminum layer or with another layer of a material which has a high thermal conductivity of at least 30 W / mK and has a reflective effect.
  • a base body made of - preferably transparent - plastic, the inside of which is coated with an aluminum layer or with another layer of a material which has a high thermal conductivity of at least 30 W / mK and has a reflective effect.
  • the present invention thus provides a simple possibility to prevent cooling of a gas discharge lamp, in particular a low-pressure discharge lamp.
  • the temperature shield by the shielding according to the invention is even so good that T16 lamps can be operated even at very low ambient temperatures below 25 ° C even at optimum temperatures.
