Definitions

  • the invention relates to a luminaire component for forming a luminaire, such as a luminaire for emergency lighting (i.e., escape route illumination) or escape/exit sign applications, and such a luminaire.
  • the luminaire component hereby is designed to be easily mounted by a user mechanically and electrically to a corresponding adapter element, forming the luminaire.
  • the lighting means and driver electronics as well as electrical connecting means of the luminaire component are all arranged on a common printed circuit board, PCB, which is accommodated inside a body molding forming a housing component of the luminaire component and thus the luminaire.
  • a housing cascading is often provided, in which individual components are formed modularly and have their own housings with external contact points, via which these modular components are then connected to other components of the luminaire or the luminaire component, whereby these modules are ultimately arranged within a common housing of the luminaire or the luminaire component, so that the luminaire or the luminaire component has increased manufacturing costs due to material consumption, complicated assembly and also an increased weight and larger dimensions.
  • the invention is therefore concerned with the task of providing a luminaire component and a luminaire with such a luminaire component, in which the installation is particularly simple and error-prone, whilst also allowing various lighting scenarios.
  • the luminaire component for forming a luminaire comprises:
  • the lighting means, the driver electronics and the electrical connecting means are arranged on a common carrier element, which is formed by a printed circuit board, PCB.
  • the electrical connecting means are combinable with at least two different external adapter elements for connection with different power supply structures and/or the body molding is combinable with at least two different light emitting elements, which emit the light of the lighting means.
  • the driver electronics and the electrical connecting means arranged on a common carrier element and the electrical connecting means being configured to connect with an external mains supply, a particularly simple and safe installation of the luminaire component is achieved, since the driver electronics are connected via connection of the electrical connecting means with a power supply automatically also to the power supply. Furthermore, by means of the common housing, which is formed by the body molding, a particularly simple assembly of the components, as well as a particularly space and weight-saving luminaire component is created.
  • the luminaire itself is embodied herein, whereas the luminaire comprises:
  • the adapter element comprises means for a mechanical connection with the body molding of the luminaire component and means for an electrical connection with the electrical connections means of the luminaire component.
  • the means for an electrical connection can be integrally formed with the means for a mechanical connection. This further simplifies commissioning of the luminaire.
  • the luminaire component for a self-contained emergency lighting comprises an emergency energy supply such as an accumulator and/or an other energy storage element, which thus is placed inside the luminaire.
  • the emergency energy supply is placed within one meter of the luminaire and connected via wires thereto, and thus forms an external component of the luminaire.
  • the electrical connecting means of the luminaire component are adapted to combine with the at least two different external adapter elements via a plug-connection.
  • This allows the luminaire component to be used in a particularly versatile manner and in different scenarios, as the plug connection facilitates mounting and thus connection of the luminaire component to the respective external adapter element.
  • an external adapter element can be provided with a direct wired connection with mains power and/or a communication line, whereby the adapter element is wall and/or ceiling mounted, whereby it is also conceivable that the adapter element is arranged in an installation opening.

  • the adapter element is preferably formed in such a way that it is completely accommodated in the interior of the respective track system, so that the luminaire component connected to the adapter element lies flush against the track system.
  • an electrical connecting means configured in this manner, a flexible coupling is thus created.
  • the mechanical connection may also lock the luminaires position towards the track system, so that the luminaires position cannot be changed after commissioning, and is thus securely mounted.
  • the luminaire component additionally comprises power storage means in the form of an accumulator, whereby the power storage means are arranged on the PCB.
  • power storage means in the form of an accumulator, whereby the power storage means are arranged on the PCB.
  • the power storage means in the form of an accumulator are reversibly mounted on the PCB within an accumulator holder element, which is fixedly mounted on the PCB.

  • the electrical coupling of the power storage means with the other components of the luminaire component only takes place if the electrical connecting means is connected to an external adapter element. This ensures that the electrical connection only exists when the luminaire component is actually installed, i.e. coupled/mounted to an external adapter element. This has the technical advantage that an additional transport safety device for the components is not required, since there is no electrical coupling between power storage means and other components of the luminaire component.
  • the external adapter element can be provided with loop-through contacts, which establish an electrical contact between corresponding lines in the electrical connecting means, and thus electrically couple the power storage means with the other components of the PCB, as soon as the electrical connecting means is coupled with the corresponding external adapter element - i.e. the luminaire is installed/mounted.

  • a present string of LEDs is driven in such a way to only actuate individual LEDs of the LED string, forming individual LED spots.
  • the operation mode is selectable via a user input device mechanical input device or via an electronic input device.
  • the respective input device is preferably arranged directly on the luminaire component.

  • the light emitting element is:
  • escape sign luminaires in particular can be created.
  • the use of an optical element that has at least one lens with a spot-like light emission creates the application range of the luminaire as escape route lighting.

  • the luminaire also includes a back cover that can be coupled to and snapped onto the body molding to close the luminaire.
  • the back cover carries the external adapter element.
  • the back cover can be pre-mounted, e.g. on a wall or ceiling or in an installation opening or on a lighting track system, whereby the luminaire component with its electrical connecting means is mechanically coupled to the back cover by means of snap connections. In this way, the body molding of the luminaire component is closed off at the top, whereas when the luminaire component is coupled to the external adapter element, the back cover is also coupled to the body molding, thus achieving a closed housing of the luminaire.
  • snap elements can be provided, preferably in an edge region of the back cover, which interact with equivalent elements of the body molding.
