Patent ID: 7518668

Claim:
A backlight unit, comprising: a lamp unit comprising a plurality of light-emitting lamps wherein electrodes are provided to respective ends of each of the light-emitting lamps; and an inverter provided to a rear side of the lamp unit to apply power to a plurality of the light-emitting lamps, wherein the inverter comprising: at least one inverter printed circuit board arranged on a lower part of the rear side of the lamp unit in a direction vertical to the convection flow direction and having long-sides parallel to the longitudinal direction of the light-emitting lamps and short-sides parallel to the convection flow direction; and a plurality of transformers and inverter elements offset from one another with respect to a convection flow direction vertical to the longitudinal direction of the light-emitting lamps in the backlight unit, arranged on the at least one inverter printed circuit board in a direction vertical to the convection flow direction and arranged in at least of a single row along the direction vertical to the convection flow direction to independently release heat despite the occurrence of the ascending convection flow, thereby preventing a temperature rise from being accelerated.
