摘要:
La présente invention concerne un dispositif d'éclairage et/ou de signalisation de véhicule automobile, comprenant: - un substrat diélectrique (2) comportant une pluralité de pistes conductrices, - une pluralité de diodes électroluminescentes (1) montées en surface sur ledit substrat diélectrique, les diodes électroluminescentes étant connectées électriquement aux pistes conductrices du substrat diélectrique selon un plan de connexion prédéterminé, - au moins un circuit de pilotage pour piloter les diodes électroluminescentes, ledit circuit de pilotage comportant une pluralité de broches de connexion, et - un circuit de liaison électrique (3) comportant une pluralité de lignes conductrices pour relier électriquement les broches de connexion du circuit de pilotage aux pistes conductrices du substrat diélectrique selon un plan de connexion prédéterminé, caractérisé en ce que le circuit de liaison électrique (3) est connecté aux pistes conductrices du substrat diélectrique (2) via un film conducteur anisotrope (4).
摘要:
The invention relates to a light source intended to be supplied with power by a voltage source. The light source comprises a parallel assembly of at least two branches, each branch comprising at least one elementary light source having an electroluminescent semiconductor element, and each of the elementary light sources has a high internal series resistance. The invention also relates to a method for manufacturing a light source according to the invention.
摘要:
The invention relates to a light module (2), especially for a motor vehicle, comprising a substrate (4), at least one light source (8, 9) arranged on the substrate (4), and a metal coating on the substrate, forming strips (14, 16, 22, 24, 26) for the electrical power supply of the light sources (8, 9). The metal coating extends at a distance from the power supply strips (14, 16, 22, 24, 26) and/or transversely to said strips, in such a way as to form at least one auxiliary area (18, 20) ensuring the function of a heat screen, a reflective surface, an aesthetic surface, and/or electromagnetic shielding.
摘要:
The invention relates to a method for managing the power dissipated by an electroluminescent light source comprising sub-millimetre electroluminescent bars projecting from a substrate and divided into a plurality of identical groups. Using the measures of the invention, it is possible to manage the dissipation of power from the light source in the event of sudden changes in the intensity of the electric current supply.
