Abstract
An image generating device comprises a light source producing a light beam and a screen (5) traversed by the light beam and designed to modify the light beam so as to form an image. The screen (5) comprises a transparent element (150) traversed by the light beam and designed to evacuate the heat generated at the level of the screen (5). Said transparent element (150) is made of sintered transparent ceramic. Also described are a head-up display comprising such a device, and a method for manufacturing an image generating device.
Claims12
An image-generating device comprising:
- a light source that produces a light beam;
- and
- a screen that is passed through by the light beam, wherein the screen modifies the light beam so as to form an image, in which device
- wherein the screen comprises a transparent element that is passed through by the light beam and that is arranged to remove the heat generated in the screen;
- wherein said transparent element is made of sintered transparent ceramic.
A process for manufacturing an image-generating device comprising a light source that produces a light beam and a screen that is passed through by the light beam and that is designed to modify the light beam so as to form an image, the process comprising:
- sintering a powder so as to obtain an element made of transparent ceramic;
- and
- mounting said element on the screen so that this element is passed through by the light beam and removes the heat generated in the screen.
An image-generating device comprising:
- a light source that produces a light beam;
- and
- a screen that is passed through by the light beam, wherein the screen modifies the light beam so as to form an image,
- wherein the screen comprises a transparent element that is passed through by the light beam and that is arranged to remove the heat generated in the screen,
- wherein the screen comprises a metal cover and the transparent element is accommodated in an interior of the metal cover.
