Title (EN) LIGHTING DEVICE, AND DISPLAY DEVICE
(FR) DISPOSITIF D'ÉCLAIRAGE ET DISPOSITIF D'AFFICHAGE
(JA) 照明装置、及び表示装置
Abstract: front page image
(EN)A lighting device (8) comprising a cold cathode fluorescent tube (light source) (9), and a chassis (8a) for housing the cold cathode fluorescent tube (9) is further provided with an inverter circuit (16) having a transformer (16a) connected with the cold cathode fluorescent tube (9) and driving the cold cathode fluorescent tube (9). In the lighting device (8), the inverter circuit (16) drives the cold cathode fluorescent tube (9) with a frequency higher than a predetermined fundamental frequency during a predetermined period in the lighting period of the cold cathode fluorescent tube (9).
(FR)L'invention concerne un dispositif d'éclairage (8) comportant un tube fluorescent à cathode froide (source lumineuse) (9) et un châssis (8a) pour loger le tube fluorescent à cathode froide (9), ledit dispositif d'éclairage étant en outre muni d'un circuit onduleur (16) comportant un transformateur (16a) relié au tube fluorescent à cathode froide (9) et pilotant ce dernier. Dans le dispositif d'éclairage (8), le circuit onduleur (16) pilote le tube fluorescent à cathode froide (9) avec une fréquence supérieure à une fréquence fondamentale prédéterminée, pendant une période prédéterminée de la période d'éclairage du tube fluorescent à cathode froide (9).
(JA) 冷陰極蛍光管(光源)(9)と、冷陰極蛍光管(9)を収容するシャーシ(8a)を備えた照明装置(8)において、冷陰極蛍光管(9)に接続されるトランス(16a)を有するとともに、当該冷陰極蛍光管(9)を駆動するインバータ回路(16)を備え、インバータ回路(16)は、冷陰極蛍光管(9)の点灯期間のうち所定の期間の間、所定の基本周波数よりも高い周波数を用いて、冷陰極蛍光管(9)を駆動する。
