Problems solved by technology

[0004] Furthermore, the electrical connections between modules, drivers and converters are not easily accomplished using the standard connection strips provided for lighting fixtures, given the number of connections they have to make and electromagnetic constraints.
[0005] In addition, the mechanical integration of all these components in the device is complex and difficult to achieve

Embodiment Construction

[0062] refer to Figures 1 to 5 The lighting and / or signaling headlights 2 of a motor vehicle are described.

[0063] In the following an orthogonal frame of reference XYZ is used, where the X and Y directions are horizontal and respectively parallel and perpendicular to the direction of travel of the vehicle, while the Z direction is the vertical direction.

[0064] The headlight 2 includes a projection device 4 which ensures the lighting function. However, it should be understood that the projection device may also provide one or more signaling functions, or it may constitute a signaling device alone.

[0065] The configuration of the headlight 2 can be formed to ensure various lighting functions by itself, and to include, for example, various projection units similar to those to be described here for this purpose.

[0066] The headlamp 2 comprises a housing 6 and a crystal or crystal 8 extending respectively to the rear of the device and to the front of the device, defini...

Abstract

The projection unit (100) has two optical modules (20) and an optical projection device (23), where each optical module is provided with LEDs (101) integral with a printed circuit board (26). A common control device (102) is provided for controlling the two optical modules, where the two optical modules and the control device are secured on a support (14). One of the two optical modules includes a heat dissipation unit (21) arranged to dissipate some of the heat generated by the LEDs, where the heat dissipation unit is in surface contact with the printed circuit board. An independent claim is also included for a projection device.

Description

technical field [0001] The invention relates to a signaling and / or lighting device for a motor vehicle. The invention relates in particular, but not exclusively, to a lighting device for providing a light beam realized in a matrix by means of a plurality of modules, each module generating a part of the light beam. Background technique [0002] In such an arrangement, each module comprises a light emitting diode (hereinafter referred to as LED) for forming the light source of the module. However, LEDs generate a lot of heat when they are in operation. The entire light beam is generated by the operation of the components of the module, where each LED is driven independently, which results in a significant rise in temperature inside the device. Therefore, measures must be taken for proper heat transfer to cool this component. [0003] In addition, this device requires two additional components. The first component is formed by a control device which ensures a matrix operati...
