    • An illumination device for a liquid crystal display apparatus to be disposed on a back side of a liquid crystal display panel is constituted by a plurality of illumination circuits, and plural hot cathode tubes including at least one hot cathode tube associated with each illumination circuit. Each illumination circuit includes a life detection circuit for detecting an end of life of a hot cathode tube, and a turn-off circuit for turning off the hot cathode tube depending on an output of the life detection circuit. Each illumination circuit controls said at least one hot cathode tube associated therewith independently from the other hot cathode tubes. As a result, even when a hot cathode tube approaches its end of life, the illumination device can be partially turned off to allow an operator to continue the operation on the liquid crystal display apparatus.

    • Un dispositif d'éclairage (D) comprend un transformateur de courant (TC) dont le secondaire alimente au moins une lampe fluorescente avec ses organes d'amorçage/régulation. En parallèle sur le secondaire sont prévus des organes d'écrêtage et d'àccord (50, 51, 52) propres à consommer, lorsque la lampe associée est défaillante, une fraction substantielle de l'énergie nominale demandée par celle-ci. De préférence, on prévoit deux lampes dans chaque dispositif, une détection (30) du fait que l'une (L1) de ces lampes ne s'amorce pas permettant de faire passer l'alimentation (I) sur la second lampe (L2).

    • PROBLEM TO BE SOLVED: To provide a method for lighting a plurality of high-pressure discharge lamps by which a restartable time immediately after light-out and a rising time of luminous flux can be shortened. SOLUTION: This lighting method is provided for lighting a regular lamp and a starting lamp having the rising time of luminous flux earlier than that of the regular lamp in combination. This method includes a step (a step S2) of setting a control mode of controlling lighting conditions of both the lamps from a time elapsed after the previous light-out of the regular lamp, and a step (a step S3) of indicating the lighting of the starting lamp and the regular lamp according to a determined control mode. Each control mode includes control for starting the lighting of both the lamps simultaneously, the light-out of the starting lamp when the starting lamp is brought into a regular lighting state and starting the regular lamp thereafter by starting the lighting of the starting lamp at first when a time has not yet elapsed after previous light-out.
