Zusammenfassung:	A direct-light illuminating backlight unit for LCD module has two elongated lamps, each of which is bent into a substantial S-shape having three straight portions and two connection portions connected with the neighboring straight portions respectively. The lamps are mounted side by side on a frame with the straight portions of the lamps are substantially parallel to each other and interval pitches between the straight portions are substantially equal to each other. Such arrangement of the backlight unit is applied to LCD modules with nominal sizes ranged from 12 inches to 17 inches and more preferably applied to modules of, in name, 14 inches or 15 inches.
