Embodiment Construction

[0045] Concepts regarding location or orientation, such as for example "above", "below", "in front of", "below", "above" etc. have been chosen in this specification for simplicity only and may not It refers to the illustration in the drawing, but necessarily to the position of use or installation.

[0046] figure 1 , 2 , 3 and 8 each show a completed assembled DMD module, for which (wogegen, sometimes called opposite), Figures 4 to 7 should be used to illustrate the assembly of DMD modules and Figures 9 to 11 Involves the DMD element itself.

[0047] The figure shows a DMD module 1 according to the invention with a holding frame 2 into which a DMD element 3 is inserted. DMD element 3 has base 4, and described base is connected with conductor plate 5 by soldering, and wherein, actual DMD chip is plugged in base 4 by pin (Pins, is sometimes referred to as pin) and in base 4 is held by means of a spring clamp (Federklemmen, sometimes called a spring terminal). See especia...

Abstract

A DMD module (1) is composed of a holding framework (2), a DMD element (3) arranged in the holding framework (3), and a plate like Peltier element (6). One side of the Peltier element is heat-conductively laminated on the back side of the DMD element and has an electric connection part. The DMD module is provided with a cooling body (7), which is in heat-conductive contact with the other side of the Peltier element. A conductor plate (5) is arranged between the DMD element (3) and the cooling body (7). The conductor plate is provided with a gap (10) for the Peltier element (6). A spring contact part (11a, b, 12a, b) and a contact surface (8,9) belonged to the spring contact part are used to electrically connect the Peltier element and the conductor plate. When the DMD module has been assembled, the spring contact part is elastically attached to the contact surface.

Description

technical field [0001] The invention relates to a DMD module (1), which consists of a holding frame (2), a DMD element (3) inserted in the holding frame, a plate-shaped Peltier element (6) It is formed that the Peltier element rests on the rear side of the DMD element in a heat-conducting manner on one side and has an electrical connection, and the DMD module has a cooling body (7), which is connected to the The other side of the Peltier element is in thermally conductive contact, and between the DMD element (3) and the cooling body (7) a conductor plate (5) is arranged, which has a gap (10) of the Peltier element (6). Background technique [0002] Such DMD modules (DMD stands for Digital Mirror Device, also called Micromirror Actuator in German-speaking regions) are used, for example, in vehicle headlights and contain actual (eigentliche) DMD components and for the described The cooling of the DMD element includes a cooling body. The DMD element forms, via the scanning l...
