Definitions

  • Linear incandescent lamps which are provided with a type S 14d base or two type S 14s bases on the outer surface of their lamp bulb, find a wide range of applications in interior lighting. Due to their uniform luminance over the entire lamp length and their relatively low luminance values, they enable free construction without the risk of glare in e.g. Cabinet walls, as mirror lighting or as emergency lighting.
  • a disadvantage of these lamps given the relatively high lamp output, is the relatively low useful luminous flux and the relatively high surface temperatures of up to 80 ° C. A light output of only approx. 7 lm / W is typical of this type of lamp.
  • Incandescent bulbs of the same power however, have a luminous efficacy of more than 12 lm / W depending on the lamp type. Despite these known disadvantages, the purchase price of a linear incandescent lamp is relatively high.
  • the object of the present invention is to create a substitute which is more economical to operate than linear incandescent lamps and which can be used in the existing lighting systems.
  • a lamp according to the invention With a lamp according to the invention, with the same external dimensions and the same bases as with the corresponding linear incandescent lamp, both a higher luminous efficiency, a lower power consumption and a lower surface temperature are achieved. These advantages are made possible by the use of a discharge tube of a fluorescent lamp.
  • the use of a discharge vessel of a fluorescent lamp results in a service life that is approximately five times that of the linear incandescent lamp.
  • the discharge vessel is held within the lamp bulb by means of several spacer rings or fixing rings.
  • modern operating electronics integrated in the lamp bulb are used, which on the one hand further increases the overall yield of the system and on the other hand keeps the weight of the lamp low.
  • the arrangement of the operating electronics with different function groups keeps possible high-frequency interference below the permissible limit values.
  • the individual printed circuit boards provided with the components and combined into functional groups favor the mechanical production of larger quantities and facilitate their installation in the remaining free spaces at the ends of the lamp bulb.
  • the non-illuminating ends of the lamp bulb, which contain the electronic ballast, are covered by a flat sleeve.
  • the support ridges act on the long sides of the circuit board on the one hand a secure support of the same on the inner wall of the lamp bulb over the entire length, on the other hand, there is sufficient space between the support webs so that the shading that occurs in the direction of the base is limited to a minimum.
  • the discharge vessel is soldered by means of its power supply directly to the side of the circuit board facing away from the base and is thereby held.
  • the components of the operating electronics are arranged on the side of the printed circuit board facing the base.
  • the prefabricated structural unit consisting of the discharge vessel and the operating electronics can be mounted inside the lamp bulb, the fixing being carried out at the intended position within the lamp bulb by means of the fixing disks.
  • the non-luminous ends of the lamp bulb are each covered by a flat sleeve. Equipped with these properties, the lamp according to the invention is fully interchangeable with the known linear incandescent lamp and, moreover, is only about half as expensive to operate.
  • FIG. 1 shows a lamp 1 with an elongated tubular lamp bulb 2, on the two ends of which a base 3 of the type S 14s is attached to the outer surface.
  • the lamp ends are each covered with a sleeve 4.
  • the lamp bulb 1 is made of glass or plastic, has an outer diameter of approximately 30 mm and a length of approximately 500 mm.
  • the inner surface of the lamp bulb 2 is provided with a light-scattering coating (e.g. internally silicided).
  • a type S 14d base arranged in the middle of the lamp bulb 2 is also possible.
  • the sleeve 4 is pushed onto the lamp bulb 2 in a clamping manner from the end of the lamp and extends somewhat beyond the base 3. It consists of a light absorbing material, e.g. made of aluminum or plastic, and covers the non-illuminating part of the lamp bulb 2.
  • the lamp end part A shown in FIG. 2 has the lamp bulb 2 of approximately 500 mm in length, the base 3 and the sleeve 4.
  • a discharge vessel 5 of a conventional fluorescent lamp is fixed inside the lamp bulb 2 symmetrically to the center of the lamp by means of a plurality of spacer rings 6 made of a clear transparent material.
  • the discharge vessel has a nominal electrical power of 15 W, an outer diameter of 26 mm and a length (without base) of approx. 415 mm. In the free spaces remaining at the ends of the lamp bulb 2, there is therefore sufficient space for operating electronics.
  • This is mounted on individual circuit boards 7 and 8, which are fixed within the lamp bulb 2 in a conventional manner, for example by means of an insulating clamping tube (made of Teflon®).
  • the operating electronics are expediently divided into individual functional groups.
  • a printed circuit board is equipped with the power supply unit, another printed circuit board with a filter and a third printed circuit board with a high-frequency generator, etc.
  • the individual electronic components of the operating electronics 9 are only shown schematically here.
  • a heat shield 10 made of mica is arranged, which protects the temperature-sensitive operating electronics 9 against the heat loss of the electrode filaments 11 of the discharge thermally insulated.

  • the leads 13 to the other, not shown, end of the lamp 1 are here between the fluorescent lamp 5 and the lamp bulb 2 on the Sockets 3 facing side of the lamp 1, wherein the supply lines 13 are arranged immovably by means of recesses which have the spacer rings 6 (not shown).
  • Another feed line 14 runs from the base 3 to the printed circuit board 8.
  • the following values apply to the electrical and lighting data (in brackets the corresponding data of the linear incandescent lamp to be substituted):
  • the electrical power of the overall lamp plus ballast system is approximately 13 W (60 W) with a luminous flux of approximately 550 lm (420 lm). This corresponds to a luminous efficacy of 42 lm / W (7 lm / W).
  • the luminance is approx. 0.5 cd / cm2 (0.3 cd / cm2).
  • a value of approx. 5000 h (1000 h) can be assumed as the economic service life.
  • FIG. 3 shows a lamp 21 with an elongated tubular lamp bulb 22, on each end of which a base 23 of the type S 14s is fastened to the outer surface.
  • the lamp ends are each covered with a sleeve 24.
  • the lamp bulb 21 is made of glass or plastic, has an outer diameter of approximately 30 mm and a length of approximately 300 mm.
