Title (EN) LIGHT SOURCE-DRIVING CIRCUIT AND METHOD FOR DRIVING LIGHT SOURCE
(FR) CIRCUIT DE COMMANDE DE SOURCE LUMINEUSE ET PROCÉDÉ DE COMMANDE DE SOURCE LUMINEUSE
(JA) 光源駆動回路及び光源駆動方法
Abstract:
(EN) This light source-driving circuit comprises: first and second light sources connected in series to a power supply; a first resistive element for setting the amount of current flowing to at least the first light source; a second resistive element for setting the amount of current flowing to the second light source; and an adjustment unit for adjusting the amount of current of at least one among the first light source and the second light source on the basis of the voltage value of the power supply.
(FR) La présente invention concerne un circuit de commande de source de lumière comprenant : des première et seconde sources de lumière connectées en série à une alimentation ; un premier élément résistif pour régler la quantité de courant circulant vers au moins la première source de lumière ; un second élément résistif destiné à régler la quantité de courant circulant vers la seconde source lumineuse ; et une unité de réglage pour régler la quantité de courant d'au moins l'une parmi la première source de lumière et la seconde source de lumière sur la base de la valeur de tension de l'alimentation.
(JA) 光源駆動回路は、電源に対して直列に接続された第1光源と第2光源と、少なくとも第1光源に流れる電流量を設定する第1抵抗素子と、第2光源に流れる電流量を設定する第2抵抗素子と、電源の電圧値に基づき第1光源及び第2光源のうち少なくとも1つの電流量の調整を行う調整部と、を備える。
