Abstract: front page image
(EN) The vehicle lamp fitting 100 of the present invention is provided with: an organic EL element 120; a lighting circuit 200 for switching the organic EL element 120 ON and OFF; and a lighting control unit 202 for controlling the lighting circuit 200 such that momentary turning off of the organic EL element 120 is repeated when the organic EL element 120 should be turned on. The lighting circuit 200 comprises a discharge path 210 which is formed at least during the momentary turning off of the organic EL element 120 such that the accumulated electric charge can be discharged from the organic EL element 120.
(FR) L'invention concerne un raccord de lampe de véhicule 100 comprenant : un élément EL organique 120; un circuit d'éclairage 200 pour commuter l'élément EL organique 120 sur MARCHE et ARRÊT; et une unité de commande d'éclairage 202 pour commander le circuit d'éclairage 200 de telle sorte que l'arrêt momentané de l'élément EL organique 120 est répété lorsque l'élément EL organique 120 doit être allumé. Le circuit d'éclairage 200 comprend un trajet de décharge 210 qui est formé au moins pendant l'arrêt momentané de l'élément EL organique 120 de telle sorte que la charge électrique accumulée peut être déchargée de l'élément EL organique 120.
(JA) 車両用灯具100は、有機EL素子120と、有機EL素子120の点灯と消灯を切り替える点灯回路200と、有機EL素子120を点灯すべき状態において瞬間的消灯が繰り返されるよう点灯回路200を制御する点灯制御部202と、を備える。点灯回路200は、有機EL素子120から蓄積電荷を放電するよう少なくとも瞬間的消灯の間に形成される放電経路210を備える。
