• 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 an electric lighting of the same area, and energy costs are about six times higher. 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, the roads or the actual road surface and partly also the bicycle or pedestrian paths or areas so that, for example, oncoming traffic or persons such as small children or objects such as flowerpots on the edge of the road can be optimally recognized without dazzling the road users.

• 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.
• Figures 6 and 7 (a) and b)) show a wide carrier body which is surrounded with a contact protection.
• the contact protection is designed as a glass tube and in FIG. 7 as a glass dome.
• the figure 6/7 a) shows a wide conical carrier body 1 in bottom view and side view.
• the carrier body 1 is provided with four or five LED bags 3.
• the LED pockets 3 are advantageously embedded in the lateral surface 5 of the carrier body 1.
• the lateral surface 5 advantageously extends from the tip 7 to the base 9 of the carrier body 1.
• Figure 6/7 b) shows the inserted into the LED pockets 3 LED boards 14, which can be advantageously supplied via the openings 17 with power.
• a power white driver can be integrated in the lampshade of the lamp, whereby an efficient power supply of the LED is made possible.
• the LED boards 14 are mounted in or on the LED pockets 3 of the carrier body 1.
• the number of LED boards 14 can be varied, whereby different light intensities can be generated.
• the carrier body 1 is advantageously surrounded by a contact protection, for example a glass tube 15 (FIG. 6) or a glass dome (FIG. 7). 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), Figure 9 a) to e) and Figure 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 produced particularly favorably and is easily tradeable.
• 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.
• the LED boards 14 can advantageously be attached to the carrier body 1 without further fastening means.
• the LED pockets 3 are advantageously arranged on the mental connection line between base 9 and tip 7.
• 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 can 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 branching. With this, all LEDs are flown through by 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.
• the number of LEDs on a board is varied, that is, different numbers of LEDs can be arranged on a board.
• 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 can 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.
