BACKLIGHT UNIT

摘要

The present invention relates to a backlight unit. The backlight unit of the present invention comprises: an optical plate constituted by at least either a light guide plate for allowing light to pass at a dispersed state or a diffusion plate for allowing light to pass at a diffused state; an LED module having a light-emitting element for providing light to the optical plate and a circuit for driving the light-emitting element; a heat pipe for absorbing heat generated from the LED module through one side thereof and transferring the absorbed heat to the other side thereof so as to dissipate the heat; and a housing for accommodating at least one of the heat pipe, the optical plate and the LED module. The LED module is directly connected to one side of the heat pipe such that the heat from the LED module can be directly transferred to the one side of the heat pipe. The backlight unit of the present invention has excellent heat dissipating performance as the heat from the LED module is directly transferred the heat pipe.
