Definitions

  • the description refers to lighting devices.
  • One or more embodiments may be applied to lighting devices using electrically-powered light radiation sources, for example, solid-state light radiation sources, such as LED sources.
  • electrically-powered light radiation sources for example, solid-state light radiation sources, such as LED sources.
  • Devices of this kind can be used both for decorative purposes and for general lighting functions, considering the possibility of providing a uniform and diffused light emission along the entire length of the device or module.
  • modules are available in various configurations, for example, with white emissions for lighting purposes and with colored light emissions, which can be used for decorative purposes.
  • top emitting modules and side emitting modules. These types of modules are characterized by the different direction of emission of the light radiation with respect to the folding direction of the module.
  • these modules can be used for decorative purposes (for example, with colored emissions, for example, RGB).
  • the light emission surface for example, of a diffused type
  • the light emission surface can, for example, be directly visible.
  • This may, for example, also apply to general lighting applications, for example, for niche or cove-lighting or for functions of the type known as "wall-wash” lighting, with diffused lighting on a wall surface.
  • the presence of connectors intended to establish such a connection can, for example, give rise to inhomogeneity of light emission at the area of the module where the connection is made.
  • aspects related to the physical dimensions of the connector must be taken into account, for example, in consideration of the fact that - if the module and the connector are placed in a profiled bar, for example, of aluminum - some applications may involve specific forming or cutting of the connector.
  • Substantially analogous considerations can be applied in the case of installation in a groove provided in a wall, a furnishing element, a false ceiling, etc.
  • some installations may involve the production of a cavity of a larger size and/or of an appropriate shape at the position of the connector in order to allow its positioning. Regardless of any other consideration, this fact can result in additional costs and a greater time commitment at the installation level.
  • the appearance of color uniformity may, for example, be critical when two or more modules placed next to each other are used. This, for example, considers the fact that, at the modules, there are cables for supplying the modules with power, which can either be connected by welding or, as already discussed above, by means of a connector.
  • a metal (profiled) rail is required, for example, of aluminum, for use as a mounting or installation structure

  • particular configurations, structures or characteristics can be combined in any suitable way in one or more embodiments.
  • one or more embodiments may relate to a method for installing a lighting device ("module") indicated - in its entirety - by 10 (for example, with a quadrangular (e.g. rectangular) cross-section) of a generally elongated shape, for example, flexible, in which it is generally possible to distinguish:
