Abstract

L'invention concerne un système de source de lumière (1) et un phare automobile. Le système de source de lumière comprend une source de lumière d'excitation (11), un dispositif électroluminescent (12) et un dispositif de commande (13). La source de lumière d'excitation (11) émet de la lumière d'excitation. Le dispositif électroluminescent (12) comprend plusieurs unités électroluminescentes (121, 121a-121d), chacune des unités électroluminescentes (121, 121a-121d) commutant entre une première position et une deuxième position en fonction de la commande du dispositif de commande (13), et recevant la lumière d'excitation et générant de la lumière excitée au moins lorsqu'elles sont dans la première position. Le dispositif de commande (13) sert à commander, selon un motif devant être projeté devant le phare de l'automobile, chacune des unités électroluminescentes (121, 121a-121d) de sorte que celle-ci soit située respectivement à la première position ou à la deuxième position, afin de former un motif désiré devant le phare de l'automobile, tel que, lorsqu'elles sont dans la première position, la lumière excitée générée par chacune des unités électroluminescentes (121, 121a-121d) entre dans un premier chemin (L1) et émerge devant le phare de l'automobile ; et lorsqu'elles sont dans la deuxième position, la lumière excitée générée par chacune des unités électroluminescentes (121, 121a-121d) entre dans un deuxième chemin (L2) pour éviter d'émerger devant le phare de l'automobile, ou chacune des unités électroluminescentes (121, 121a-121d) ne peut recevoir la lumière d'excitation afin de générer de la lumière excitée. Le champ d'application d'un système de source de lumière est étendu, et les fonctions d'indication d'un phare d'automobile sont enrichies.
