PURPOSE: A luminescent substrate structure of an LED backlight unit is provided to prevent the deterioration of a component including a high luminescent LED device of an LED backlight and to irradiate heat which is generated from an LED panel of a backlight unit for increasing the brightness of an LED panel. CONSTITUTION: A heat absorption base of each light emitting substrate or a circuit unit(112) is respectively connected to a heat conduction pipe. The heat conduction pipe is fixed to a radiating unit(20). An LED light substrate is arranged to be laminated on the rear side of an LED panel. The heat conduction pipe is fixed to the radiating unit. A light radiating plate(21) radiates heat to the outside through the heat exchange action with air. |
