Definitions

  • the present invention relates to a lighting device according to the preamble of the main claim and in particular a new industrial product for use in lamp holders, especially in street lighting.
  • the invention also relates to light-emitting diodes (LED) illuminants, preferably for classic versions, which can be used in particular as replacement light body for gas lanterns.
  • LED light-emitting diodes
  • the gas lighting is a lighting form in which a combustible gas serves as a light source. While in the early days of gas lighting in particular so-called town gas from the coal gasification was used, one uses today mainly natural gas as a combustible gas. The gas is directed through a network of pipelines to the lighting elements. Gas lanterns initially spread mainly in cities that had their own gas industry. In Germany these were for example Berlin and Hanover or Frankfurt am Main and Dresden. This kind of lighting spread quickly all over the earth, with the gas lanterns first lit by lantern lighters; later this process was automated.
  • gas lanterns consume about twenty times as much energy as would be required for electric lighting of the same area and the energy cost is about six times that. For this reason, despite the renaissance of gas lanterns, it is planned, for example, to switch to electric lighting in German cities, which still have numerous gas lanterns. Even if the consumer perceives the warm, continuous light spectrum in gas lanterns in street lighting, it is desirable for safety reasons to illuminate the streets or the actual road surface and in part also the bicycle or pedestrian paths or areas that, for example, oncoming traffic or persons such as small children or objects such as flower tubs are optimally recognized on the edge of the road, without the street users are dazzled. While road safety regulations result in sections of the road being electrically lit, there are numerous urban initiatives that aim to reintroduce gas lanterns. For example, in various surveys, about 80 to 90% of the population have argued in favor of preserving gas lanterns.

  • the conical shape of the carrier body surprisingly leads to a radiation angle, which leads to an optimal and efficient illumination.
  • the cylindrical or angular shape of the carrier body has many advantages over the prior art. For example, these carrier bodies can be produced cheaply and are well tradable by the characteristic shape, that is, a person skilled in the art can easily install and remove the carrier body. Furthermore, by shortening the length of the cylindrical or angular support body, the luminous intensity can be varied. The luminosity of the lamp can thus be adjusted by the simple replacement of the carrier body. For example, if a luminaire in a place needs to be brighter or weaker for a short time, a corresponding support body can be used without further complex modifications of the luminaire. Surprisingly, the non-conical carrier body allow a longer operation of the lights. The shape of the carrier body surprisingly prevents the lamp from becoming so hot that damage is caused. As a result, the maintenance intervals of the lamps are reduced and the lifetime of the lamp is increased.

Through the openings, the inserted into the LED bag 3 LED board 14 can be powered. The openings 17 can also be used for fastening or securing the LED boards 14.
  • the carrier body 1 has an inner space 13 which preferably accommodates a heat pipe serves. The heat pipe transfers the heat generated by the LEDs from the carrier body 1.
  • the compact shape of the wide conical carrier body 1 makes it possible that by replacing the gas lamps with LED boards 14, no loss of quality.
  • the light generated by the carrier body 1 is similar to that of the gas lamp, but is much cheaper to operate and maintain.
  • a lighting device, which is equipped with a conical carrier body, is advantageously suitable as a so-called bollard light. These are low lighting devices, which are preferably placed in public places.
  • the conical shape of the carrier body allows a compact design of the lighting devices, which are particularly advantageous for the bollard lights. The lights are bright despite their compact design and have a large illumination radius.

  • the carrier body 1 is advantageously provided with a contact protection, for example a glass tube 15 (FIG. FIG. 6 ) or a glass dome ( FIG. 7 ) surround. In this way, on the one hand, the carrier body 1 can be protected and, on the other hand, different light effects or light intensities can be produced by the contact protection.
  • FIG. 8 a) to j), FIG. 9 a) to e) and FIG. 10 a) to e) show a further preferred embodiment of the carrier body in different views.
  • the carrier body 1 has a cylindrical or rectangular shape, but may also be shaped as a polygon. This shape of the carrier body 1 can be made particularly cheap and is easily traded.
  • the LED bags 3 are arranged opposite one another. By this arrangement, a uniform light intensity and light scattering is generated, which is considered to be particularly advantageous in gas lamps, since the lights often have to illuminate a large area.
  • LED boards 14 are mounted, which are preferably powered via openings 17 in the base 9 with power. The openings 17 can also serve to hold or secure the LED boards 14.

  • an interior 13 is inserted, are advantageously admitted into the one or more heatpipes.
  • the number of LED boards 14, the light intensity can be changed. That is, long LED boards 13 produce a higher light intensity than short LED boards 13. This may be particularly advantageous when the luminous intensity of a luminaire is to be changed without, however, modifying the luminaire.
  • a longer LED board 13 or a carrier body with a larger number of LED boards 13 are integrated into the lamp to increase the luminosity.
  • the LEDs introduced into the LED pockets 3 are preferably connected in series.
  • the connection of the LEDs has no branch. This flows through all the LEDs with the same current. It was completely surprising that the failure of one LED does not cause the failure of other LEDs. This advantageous arrangement of the LEDs, a continuous illumination of important places or places can be ensured. It is also preferred that the number of LEDs on a board is varied, that is, different numbers of LEDs can be arranged on a board. As a result, a simple change in the light intensity is also possible.
  • the carrier body 1 may be coated with a layer, for example gold, whereby different light effects can be produced.
  • the light intensity by, for example Light reflection can be changed.
  • the carrier body 1 may be surrounded by a contact protection, which protects the carrier body 1.
  • the contact protection can be designed in various forms, for example as a glass tube or glass dome. The glass can also be modified, changing the light intensity or creating lighting effects.
