Definitions

  • the present invention relates to a lighting device with a solid state lighting light source.
  • a conventional lighting device such as a table lamp, a bed lamp, a or a ceiling lamp, has some kind of a supporting structure, such as a lamp foot, or a support plate to be fastened at a wall or in the ceiling, and further a lampshade or a reflector for screening or directing the light, and a socket for receiving an exchangeable bulb, such as an old style bulb, a spotlight, or a LED bulb.
  • the lighting device also has electrical wiring and contacts integrated with the supporting structure and ending with a cable with a plug, for LED applications including a transformer, at the end to be inserted into a mains socket, or just loose wires to be connected to a wire holder, typically for mounting at the ceiling.
  • LED light sources Since the LED light sources have been developed to last for a long time, such as 10 000 hours or more, also lamps with fixed, i.e. non-exchangeable, LED light sources have been put on the market. They are supposed to last for many years and when the LED light source fails the lamp is supposed to have become outdated, so that the user will buy a new one.
  • the lamps with a fixed light source are undesirable.
  • the lamps with replaceable LED bulbs there is still a risk that the user has become tired of the lamp when it is time to exchange the LED bulb and will through away the whole lamp although that is not necessary from a perspective of functionality.
  • the lamps are complex products involving many different materials combined and mounted in a way that makes them difficult to recycle, they have or will become an environmental problem.
  • a lighting device comprising a base element, a solid state lighting light source demountably mounted at the base element, and a light guiding optical unit demountably mounted at the base element, for guiding light emitted by the light source.
  • the base element comprises a support seat arranged for receiving an external support protrusion, electrical wiring connected with the light source and with a cable interface, and extending past the support seat.
  • the lighting device includes demountable parts and, in turn, is mountable at any kind of support protrusion.
  • the support protrusion can be part of a very simple single material support structure, or easily separable and recyclable support structure, which can also be replaced at any time with another one.
  • the support structure can be a lamp foot, a flexible arm, or any kind of supporting structure, which is fully separated from the electrical parts, which are included in the very lighting device. Consequently, the sustainability problem has been solved or at least reduced.
  • solid state lighting is well defined within the field of lighting devices, and is understood by the person skilled in the art as particular types of light sources such as LEDs (Light Emitting Diodes), and OLEDs (Organic Light Emitting Diodes), etc., and any similar light sources that may come in the future.
  • the support seat is constituted by a hole through the base element.
  • the hole is generally circular and is provided with a rotation preventing portion at its periphery.
