Patent ID: 7967490

Claim:
A backlight unit of a direct type comprising: a plurality of makeup Light-Emitting Diode (“LED”) modules including an LED package of a direct type on a Printed Circuit Board (“PCB”) and a heat sink under the PCB releasing heat generated from driving the LED package of the direct type; a reflection plate reflecting light emitted from the makeup LED modules to a front face, and attached at a remaining surface except for the makeup LED packages; and the optical sheet disposed on the reflection plate, and improving brightness and uniformity of the light emitted from the makeup LED module and the reflection plate, and guide the light into a front face of the optical sheet; a frame including a guide rail for combining the makeup LED modules by a sliding combination; and a guide rail combination part disposed at a side face of each makeup LED module to combine with the guide rail of the frame by a sliding combination, wherein the guide rail combination part is formed at the heat sink attached to a lower part of the PCB of each makeup LED module.
