Light source device of backlight unit for display

Abstract

A light source device of a backlight unit in which a circuit board on which light-emitting diodes (LEDs) are mounted is disposed inside a rear cover and a heat dissipating means for dissipating heat generated from the LEDs to an outside is disposed between the rear cover and the circuit board. The circuit board is implemented as a patterned substrate which includes a thin sheet and a conductive pattern formed on the thin sheet, the conductive pattern connecting the LEDs to a power source, thereby reducing a thickness through which the heat generated by the LEDs is to be conducted to the heat dissipating means. The heat generated from the LEDs can be more rapidly and efficiently dissipated. Due to the more simplified structure, the light source device can be decreased in weight and be rapidly assembled.
