Definitions

  • the present invention relates to lighted exit signs and emergency signs and, more particularly, to a dynamic exit sign.
  • Exit signs and emergency signs are widely employed in commercial and industrial buildings as well as in multi-unit residential buildings to identify exits and provide other information to persons who may be within the structure.
  • Route direction indication signs for movement of people usually consist of pictograms representing arrows that are fixed in a certain direction. Some such signs are continuously illuminated, others are illuminated only in the event of emergencies such as the loss of power, and still others are illuminated by the building power supply normally and by battery power when building power is lost.
  • An existing solution for indicating variable route direction consists in utilizing light emitting diodes (LEDs) which are controlled to effect dynamic illumination of exit signs.
  • LEDs light emitting diodes
  • Such solution involves the use of a relatively large number of spaced light emitting diodes disposed according to a pattern corresponding to the configuration of arrows oriented in multiple direction and depending on which light emitting diode of the pattern is activated, several different route direction indications can be showed.
  • Compliant solutions which can include a color display screen (such as TFT) able to display a bitmap image of the arrow with the desired orientation, or include a motorized rotating arrow.
  • TFT color display screen
  • the existing compliant solutions are complex electrically and/or mechanically and then costly.
  • the invention achieves its object thanks to a dynamic exit sign for displaying a route direction indication according to claim 1.
  • the dynamic exit sign according to the invention can be made compliant to the standards mentioned above. Indeed, via the approach of dividing the arrow area in adjacent surface light zones of square shapes and triangular shapes, which can be switched on and off independently in the safety colors required, the illuminated display module is capable of showing a dynamical arrow with several different directions by complying with the exit sign layout requirements both in terms of global geometric shape and in terms of safety colors (green) and contrast color to the safety color (white), contrarily to the known solutions where the arrow is constructed out of individual dots (LEDs).
  • LEDs individual dots
  • an additional layer of reflective and/or diffusing material is arranged at the surfaces inside each of said square and triangular compartments in order to optimize the illumination of the viewing side of each of said square and triangular compartments.
  • said illuminated display module comprises two said matrix of square and triangular compartments adapted to be stacked together with a diffusing layer in between on said printed circuit board, said semi-transparent projection layer being disposed on top of the stacking.
  • said punctual light sources comprise variously colored light emitting diodes (LEDs) or possibly RGB LEDs.
  • the sign 10 according to the invention dedicated to dynamically display a directional arrow 12 comprises an assembly 11 of adjacent surface light zones, respectively surface light zones 111 of square geometric shape and surface light zones 112 of triangular geometric shape, forming together a display matrix of the arrow area having a global square shape.
  • Each of the surface light zones can be activated independently in one and/or another of the safety colors requested by the standards on emergency escape route indications, namely green and white.
  • the arrow area of the sign 10 of global square shape is then divided into a plurality of square and triangular elementary shapes, namely the plurality of surface light zones 111 of square geometric shape and surface light zones 112 of triangular geometric shape, which are disposed together so that they can display the drawing of an arrow according a compliant, conventional fixed (non dynamic) emergency escape route sign, depending on which surface light zones of the assembly 11 are activated, and in which color.
  • the dynamical white arrow 12 displayed by the sign 10 according to the invention is able to indicate the four cardinal directions on a green background by appropriately controlling the independent activation of the plurality of adjacent surface light zones dividing the arrow area and the color thereof (white or green) according to whether the controlled surface light zone enter in the formation of the white arrow or the green background.
  • the particular assembly 11 of surface light zones of square and triangular shape is also adapted to display a prohibition sign, for instance a red cross 14, by switching on in red color the surface light zones of the assembly 11 disposed along the diagonals of the global square shape of the arrow area and by switching off the others.
  • a prohibition sign for instance a red cross 14
  • Figures 2 and 3 shows a practical embodiment for implementing the assembly 11 of surface light zones of Figure 1 enabling to display a compliant dynamic sign .
  • the latter comprises a printed circuit board 13 of square global geometrical shape and a plurality of spacers 15 projecting from the printed circuit board 13, for instance with a total height of 10 mm to 40 mm, and forming a matrix 16 of square and triangular compartments as illustrated in figure 3 .
  • Said matrix 16 of compartments can be molded in one piece from a plastic material and presents a square global shape complementary of the shape of the printed circuit board 13 on which it is dedicated to be mounted.
  • the spacers 15 are then adapted to form a matrix of 5 x 5 square compartments 17 of for instance 15x15 mm to 60x60 mm, some of which being divided in two or four triangular compartments 18 by the spacers 15.
  • the central square compartment of the matrix 16 of compartments is bordered on each of its sides with a square compartment divided in four triangular compartments by spacers extending along of its diagonals, and the square compartments adjacent to the central square compartment only by their respective corner are each divided in two triangular compartments by a spacer extending along their diagonal opposite to the corner adjacent to the central square compartment.
  • a triangular compartment is formed in each square compartment opposite to the central square compartment in view of each the square compartment divided in four triangular compartment by spacers extending along half the diagonal from each corner adjacent to the square compartment divided in four triangular compartment.
  • LEDs 19 Light Emitting Diodes 19
  • RGB LEDs Red and Green
  • all LEDs are switched in groups of 2 to more than 10 LEDs. For instance all red LEDs are switched on and off together.
  • a semi-transparent projection layer 20 is mounted on top of the matrix 16 of compartments to cover it so that the light emitted by the LEDs 19 mounted on the printed circuit board 13 in each of the square and triangular compartments of the matrix pass trough the semi-transparent projection layer 19 on the viewing side of the sign.
  • each compartment of the matrix of compartment thus illuminated forms a corresponding surface light zone of the exit sign.
  • an additional layer of reflective and/or diffusing material is arranged at the surfaces inside each of square and triangular compartments in order to optimize the illumination of the viewing side of each compartment.
  • the sign comprises two stacked matrix of compartments with a diffusing layer in between and the semi-transparent projection layer is disposed on top of the stacking.
  • This embodiment allows to improve the uniformity of illumination of the viewing side across the stacked compartments with the diffusion layer in between.
  • Compliancy with the related standards of the indication of dynamic route directions by means of the assembly according to the invention is brought about by an appropriate control of the illumination color and illumination level (brightness) of each illuminated compartment of the matrix of square and triangular compartments used for displaying the dynamical arrow. Then, according to the invention, a dynamic sign can be displayed with colors, illuminations levels, uniformity of illumination and contrast can be all made compliant with the requirements of the related standards.
