  • the source of light radiation 12 can be mounted on a respective board 14 for example taking the form of a printed circuit board (PCB) on which can be assembled circuit elements 16 which may comprise spring contacts 160a capable of deriving the electrical supply power for the radiation source 12 from a line (rail) 162 mounted on the housing of the device 10, potentially including con ⁇ trol/processing circuitry (for example a microcontroller) 164 capable of receiving and/or of exchanging signals with respect to the external environment of the device (for example, control signals or feedback signals on the operation of the device 10) via contacts 160b cooperating with one or more lines (rails) 166 installed on the housing of the device 10.
  • PCB printed circuit board
  • the source of light radiation 12 is mounted on a first face 14a of the board 14 turned (upward, in the orientation of the figures) in the direction of the opening part of the housing of the device 10 which, in the examples considered here, can have the general configuration of a channel.
  • a reflector and/or diffuser element 18 (for example made of molded transparent plastic material, potentially colored) , designed to project the light radiation produced by the source 12 toward the outside of the device 10, is installed in this opening part.
  • the body 18 has, if ob- served in transverse cross section (see figures 4 and 5) , a generally divergent form starting from the light source 12 with :

  • the board 14 can be applied in con- tact, for example in extended surface contact, via its second face 14b, with the base side of the housing of the device 10.
  • the device 10 can be designed to ac ⁇ commodate an electrically powered light radiation source ca- pable of generating heat during operation (precisely as does an LED light radiation source) and has a general box shape, for example approximately a parallelepiped with the upper surface 18a curved in a tile shape, comprising several sides amongst which may be identified (as may be observed in fig- ures 1, 4 and 5 in coordination with figures 2 and 3) :
  • a first face A (identified, in the exemplary embodi ⁇ ments illustrated here, as the external surface 18a of the reflector/diffuser element 18 associated with the source 12) forming an optical interface through which the light radia- tion is emitted from the device 10,
  • ⁇ a second face B (identified, in the exemplary embodi ⁇ ment considered here, as the base side of the housing) form ⁇ ing a thermal interface through which the heat generated by the light radiation source 12 can be dissipated to the out- side of the device, for example, toward a heat dissipater not specifically shown in the drawings,
  • At least one third face C (identified, in the exem ⁇ plary embodiment considered here, as the two opposing lateral faces of the channel-like configuration of the housing of the device 10, carrying electrical contacts such as for example the rails 162 and 166) forming an electrical interface for the distribution, toward the source 12, of the electrical power supply and for the possible transmission of signals re ⁇ ceived by/sent from the "intelligence" installed in the de- vice, for example in the form of a microcontroller 164.
  • the third face C (electrical interface) is divided into two in the form of the two opposing faces (as seen in figures 4 and 5 in coordi ⁇ nation with figure 3) of the housing of the device, with one of the faces (on the left in the view in figures 4 and 5) which performs the function of electrical interface for the electrical power supply for the sources 12 (rail 162), whereas the opposite face (on the right in the view in fig ⁇ ures 4 and 5) carries out the function of electrical inter ⁇ face for the signals relating to "the intelligence" of the device 10.
  • it is accordingly possible to sepa ⁇ rate the functions of optical, thermal and electrical inter ⁇ facing by assigning:
  • each surface of the device or module 10 can therefore be "specialized" in the performance of a particular function.
  • the lateral electrical connection offers free space and a high level of flexibility for the interfacing of the wall surface with a wide range of functions for power supply and intelligent communication.
  • Various embodiments therefore allow the production of a com ⁇ pact integrated system (for example using LED radiation sources as light radiation sources) capable of demonstrating a high level of reliability deriving from the fact that each of the light source functions is assigned to a different sur- face of the device, in an independent and completely dedi ⁇ cated manner.
  • a com ⁇ pact integrated system for example using LED radiation sources as light radiation sources
  • the choice - as electrical interfac ⁇ ing surface C - of one or both of the side walls can offer the advantage that, in various embodiments, the relevant di ⁇ mension of the housing (the vertical dimension according to the observation viewpoint of the figures) can be specifically designed according to the electrical power sup ⁇ ply/communications requirements.
  • the dimension of the thermal interface (face B, bottom face in the exemplary embodiment illus ⁇ trated here) for example allows a possible increase in the power of the light source 12 to be taken into account in co- ordination with the power supply/communications requirements associated with the electrical interface C.
  • an increase in the power of the source of light radiation 12 which is not accompanied by an increase in the complexity of the electrical interface can be taken into account by increasing the size of the thermal interface B (for example by doubling the width of the housing) leaving the vertical dimension of the same unchanged.
  • an increase in the complexity and flexibility of the electrical interface which is not accompa ⁇ nied by an increase in the power of the source of light ra- diation 12 can be handled by increasing the corresponding dimension (vertical, in the figures) of the interface C leaving the dimensions of the thermal interface B unchanged, which dimensions may for example be minimized (hence optimized) , in a totally independent manner, by taking only the requirements of the heat dissipation into account.
  • the two electrical and thermal functions are rendered "orthogonal" and hence independent from one another. This allows, for example, in the presence of more devices 10 designed to cooperate together, the electrical connection to be made through the lateral faces C of the juxtaposed devices without affecting the other optical and thermal interfacing functions .
