Abstract
The invention proposes a lighting device for a motor vehicle. Such a device includes one or more electronic circuits incorporating electronic components sensitive to an electrostatic discharge. Thanks to the features of the invention, the components are protected by encouraging the controlled flow to ground of any electrostatic discharges. All portions of one or more electronic circuits can therefore be protected by preventing random electrostatic discharges liable to destroy or to degrade sensitive electronic components.
Claims20
Lighting device for a motor vehicle, including a substrate on which is arranged at least one element of an electronic circuit including at least one electronic component sensitive to an electrostatic discharge, and
- a structure that is distinct from the substrate and liable to carry electrical charges, the shortest distance between the structure and each of the elements of the circuit being equal to D1, and
- an electrically conductive means connected electrically to ground, wherein the device comprises at least one protective element protecting against electrostatic discharges which is disposed on the structure and linked electrically to the latter, the smallest distance between the protective element and the electrically conductive means, D2, being less than D1.
