  • The present invention relates to a lighting device which has a luminous element with an LED illuminant and a power supply device for supplying the luminous means with current. Moreover, the present invention relates to a luminous element and a power supply device for use in such a lighting device.
  • Due to the better efficiency, which allows a significant power savings, conventional bulbs, such as incandescent and neon tubes, are increasingly being replaced by LED bulbs. In such substitutions, it is advantageous if no or only minor changes must be made to the existing installations.
  • Accordingly, LED modules are marketed as replacement bulbs together with the necessary control electronics in designs that can be used with little effort in existing versions.
  • The existing designs are optimized in their shape and in their characteristics to the type of light generation conventionally performed in them. Thus, the shape of the incandescent lamp is adapted to the particular conditions of a filament, neon tubes as a special form of gas discharge lamps have an elongated, rod-like shape.
  • The invention is based on the object to provide a lighting device of the type mentioned, which can be used in existing installations and which takes into account the special properties of lighting and control electronics.
  • To solve the problem, a lighting device of the type mentioned is proposed, in which the power supply device is formed separately and separable from the lighting device.
  • In lighting devices of the type mentioned, both the light source and the power supply device are more expensive compared to conventional bulbs. At the same time, the LED illuminant and the power supply device have different lifetimes. It often happens that the power supply device has an age-related defect before the light source is no longer usable. The lighting device according to the invention makes it possible to continue to use the lighting means and to replace only the defective power supply device. This ensures cost savings and also protects the environment.
  • Advantageous embodiments are the subject of the dependent claims.
  • The lighting device may be rod-shaped and in particular have the form of a standardized neon tube. In addition, the lighting device may have electrical connections that correspond to those of a standardized neon tube. As a result, a change of existing versions for neon tubes for installation of the lighting device is no longer necessary.
  • In addition, the object is achieved by a luminous element for use in the lighting device, which has a receptacle for a separately configured power supply device for the regulated supply of LED lighting with power.
  • The luminous element is thereby exchangeable independently of a power supply device used therewith. It is also possible to use any power supply device with this light-emitting element.
  • The receptacle of the luminous element advantageously has a heat-insulating layer which thermally insulates the illuminant against the receptacle.
  • The aging of LED bulbs, unlike incandescent bulbs, significantly depends on the ambient temperature. A heat source in a lighting device of the type mentioned is the power supply device, for their installation, the recording is provided. By a thermal insulation of the bulb against the recording, the life of the bulb is increased, since the heat generated by the power supply device is passed on to a lesser extent than without the insulation to the bulb.
  • On an outer side, the luminous element advantageously has cooling ribs at least in sections.
  • Due to the enlarged compared to a smooth surface surface of the cooling fins that give off a larger amount of heat to the surrounding air. As a result, the lighting device and thus also the lighting means is cooled and increases its life due to the lower operating temperature.
  • Also solves a power supply device, the task for use in a Lighting device of the type mentioned above and can be coupled to supply the lighting means with power to the light emitting element.
  • Such a power supply device can be replaced in the event of a defect, without the bulb would have to be replaced at the same time.
  • On an outer side, the power supply device has at least partially a heat-insulating layer.
  • Such a heat-insulating layer makes it possible to control in which areas of the outside heat dissipated by the power supply device is dissipated. In particular, heat-sensitive components connected to the power supply device can be protected from the heat generated by the power supply device. If these heat-sensitive components, for example, LED bulbs, so their life is significantly extended by the heat-insulating layer.
  • The power supply device may have at least partially cooling fins on an outer side.
  • The cooling fins can emit heat generated in the power supply device better to ambient air than smooth surfaces.
  • The power supply device may have a voltage converter, in particular a power supply unit, for converting a supply voltage into an operating voltage of the lighting device. Such a voltage converter ensures that the power supply device can be used to supply the illuminant with power from a power grid.
