  • the latter comprises a matrix of micro-mirrors adapted to be pivotally controlled by individual way.
  • Such a microsystem is commonly called a micro-mirror array or DMD (acronym for "Digital Micromirror Device”).
  • DMD digital Micromirror Device
  • Each mirror can take two positions: it can tilt from 10 to 15 ° along the same axis so as to reflect the light either towards a diffusion lens or towards an absorbing surface. They say he switched "on” or “off” this regime is therefore binary.

  • the figure 2 illustrates the optical components of the luminous device 2 of the figure 1 . These can be observed include a diaphragm 24 formed by a tongue 24.1 provided with a 24.2 orifice. The latter is disposed between the electromechanical microsystem 8 and the optical projection device 22. The role of the diaphragm is to cut the light rays which propagate too far from the nominal position to ensure a good definition, that is to say to say a good dive, from the image created by the system.
  • the projection optical device 22 comprises a first lens 22.1 of the convergent type and a second lens 22.2 of the divergent type. The second lens has a substantial thickness to the point of having a generally cylindrical shape.

  • the Figures 3 and 4 illustrate the luminous device of the figure 1 , without the plate and the electromechanical microsystem, seen from the underside of the support.
  • the support 4 further comprises an element 28 for partially closing the cavity 30 within the body 10.
  • This element 28 is formed by a plate 28.1 provided, at a peripheral portion, with means for attachment to the body 10, such as in particular holes for receiving fixing screws.
  • the plate 28.1 is also provided, at a central portion, with an opening 28.2. This is intended to allow light from the shaping lens 20 to meet the optical part of the electromechanical microsystem disposed opposite the opening 28.2 in question.
  • the element 28 may for this purpose include pads 28.3 forming bearing surfaces of the electromechanical microsystem. These pads 28.3, advantageously three in number to be isostatic, form surfaces comparable to point surfaces.
  • the electromechanical microsystem attached to the printed circuit board can then be fixed to the support so that the electromechanical microsystem is in pressure on the pads 28.3, thus ensuring contact and hence exact positioning in the direction perpendicular to the face 10.3 of the body 10.
  • Means for positioning the plate, in the plane of said plate may be provided, such as pins through holes in the plate and in the body 10 at the face 10.3.

  • the proximity between this beam and the edge of the tongue 24.1 at the orifice 24.2 is visible at the figure 2 .
  • the figure 4 corresponds to the figure 3 , where however the element 28 is absent.
  • the first lens 22.1 of the projection optical device 22 is held in place on the body 10 by means of a first flange 32.
  • This can have an open profile, in this case U, with the opening directed to the forming lens 20.
  • the shaping lens 20 and the first lens 22.1 are in fact very close to one another so that no space is available for a flange portion between the two lenses.
  • the first flange 32 is advantageously fixed to the body 10 by screws engaging in threaded holes made in said body.
  • the figure 5 is a sectional view of the light device of the figure 1 , the section being in a median longitudinal plane, that is to say in a plane generally parallel to the plane of the figure 1 and passing in the center of the device.
  • the device in section at the figure 5 is shown without the printed circuit board and without the electromechanical microsystem.
  • the shaping lens 20 comprises two attachment lugs 20.1 and 20.2 ( figure 2 ), these two ears being advantageously diametrically opposed. They are housed in cavities formed in the body 10, so as to ensure an angular orientation of the forming lens 20, the latter may not be symmetrical in revolution.
  • a second flange 34 in this case circular and closed, is disposed on the peripheral edge of the forming lens 20, including the ears, and is fixed to the body by means of screws.
