Title:
LAMP RETAINING MEMBER, BACKLIGHT DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, AND LAMP RETAINING METHOD
Document Type and Number:
Japanese Patent JP2008066281
Kind Code:
A
Abstract:

To provide a lamp retaining member that prevents erroneous mounting and breakage of a fluorescent lamp upon mounting fluorescent lamps and that reduces or eliminates the irregularities of luminance of a backlight due to a luminance difference arising in the direction of the tube axis of the fluorescent lamps.

A fluorescent lamp retaining member 5 retains two lamp units each including two fluorescent lamps 21 that have electrodes at both ends thereof, a bundling member 213 that bundles a wire from each of electrodes at one end of the two fluorescent lamps 21, and a conductive member 214 that connects electrodes at the other end of the two fluorescent lamps through a conductive path. The fluorescent lamp retaining member 5 holds the vicinity of the central of each of the fluorescent lamps 21 so arranged in parallel as to set the bundling members in the same direction. The fluorescent lamp retaining member allows one retained lamp unit to rotate relative to the other retained lamp unit adjacent thereto, and so retains the lamp units adjacent to each other that the bundling members 213 and conductive members 214 are arranged alternately after one lamp unit has been rotated.
