  • the masking element 22 is adapted to prevent the output via the aperture (s) 02 from the light rays reflected by the mirrors located in the second position and along an optical path between the mirror module 16 and the second aperture 02.
  • the masking element 22 is for example in the form of a blade of material.
  • This blade has any shape. For example, it is flat. Alternatively, it is curved.
  • the masking element 22 has a surface opaque to the light generated by the source 14. This surface is arranged on the optical path between the mirror module 16 and the second opening, this surface intersecting the optical path in question. so that the light rays do not reach until the second opening 02.
  • the masking element 22 extends from the wall in which the or one of the second openings 02 are made. It then forms for example a lip extending from the wall. It then extends into the interior volume 23, and / or outside the housing.
  • the masking element 22 is located away from the wall in which the or one of the second openings 22 are formed.
  • the housing 12 extends within the interior volume. It extends for example from one wall of the housing 12 to another which do not have an opening 02, where it is fixed by its ends.
  • the module comprises at least two masking elements.
  • the two masking elements delimit between them a fluid circulation channel opening out of the housing 12 via the or a second opening 02.
  • At least one flow of fluid generated by the cooling module 20 and flowing in the interior of the housing 12 flows in contact with at least one masking element 22.
  • the putting into operation of the light emitting device 2 results in the emission, by the light emitting source 14, of light rays within the interior volume delimited by the housing 12 of the light emitting module 10.
  • At least part of these light rays is sent towards the mirror module 16, whose mirrors reflect these light rays in the direction of the shaping optics or away from it as a function of the position in the mirror. which they are at the corresponding moment.
  • each mirror is for example modified over time, depending on the beam F desired at a given time.
  • the light rays reflected by the mirror module 16 away from the shaping optics 18 cause an accumulation of heat within the module 10, in particular the area of the housing towards which the mirrors reflect the light in second position.
  • the rays emitted by the source towards the walls around the mirror module 16 also contribute to this heat.
  • the cooling module 20 generates the fluid stream (s) which enter the housing through the first opening (O1) and circulate in the interior volume of the housing, possibly passing in contact with the masking element (s). come out through the second opening or openings.
  • the second fluid flow circulates in contact with the source 14.
  • the masking element or elements 22 prevent the output via the aperture (s) 02 from the light rays reflected by the mirrors arranged in the second position.
  • the invention has several advantages.
  • the presence of the cooling module makes it possible to lower the temperature of the device 2 substantially in general during its operation.
  • the heat that tends to accumulate in the housing is thus advantageously dissipated.
  • the use of the masking elements is particularly advantageous in the configurations in which the flow of fluid flows in the region of the highly heated housing by the mirrors which reflect the light away from the optical setting. form. Indeed, the presence of the second or openings then does not result in an output of light rays through these openings in the housing. Thus, it is not necessary to add to the module 10 specific external equipment to obtain an optical rendering equivalent to those of current devices.
  • the light emitting module according to the invention contributes to greatly attenuate the heat requiring the various elements of the light emitting device while not degrading the light rendering obtained.
  • the source, the mirror module and the shaping optics have been described as received in a port of a wall of the housing.
  • the light emitting source 14, the optics 18 and / or the mirror module 16 are opposite the orifice but are not arranged directly in the orifice.
