Backlight unit having light emitting diode
First Claim
1. A backlight unit for a Light Emitting Diode (LED) display device, the backlight unit comprising:
- a base member; and
a light source unit on the base member and comprising p light source blocks sequentially arranged to emit light, where p is a natural number equal to or greater than 2,wherein each of the light source blocks comprises at least one LED package, the LED package comprising;
an LED configured to generate light in response to a driving voltage applied from the outside,a main lead connected to the LED and configured to apply the driving voltage to the LED,at least one sub lead separated from the main lead and configured to provide the driving voltage to an adjacent light source block, anda body unit configured to fix the LED, the main lead, and the sub lead,wherein the main lead and the sub lead overlap the body unit in planar.

Abstract
A backlight unit has a Light Emitting Diode (LED). The backlight unit includes a base member, and a light source unit provided on the base member and including p light source blocks, where p is a natural number equal to or greater than 2. The light source blocks are sequentially arranged to emit light, and each of the light source blocks includes at least one LED package. The LED package includes an LED configured to generate light in response to a driving voltage applied from the outside. A main lead is connected to the LED and configured to apply the driving voltage to the LED. At least one sub lead is separated from the main lead and configured to provide the driving voltage to an adjacent light source block.

19. A light emitting diode (LED) backlight unit for an LED display device, the LED backlight unit comprising:
-
multiple light source blocks mounted on a base member, each light source block comprising multiple LED packages, wherein each LED package has a body unit for mounting an LED on the base member, a main lead connected to the LED, and at least one sub lead separated from the main lead, wherein the body unit comprises a groove part having tapered walls, the LED being mounted within the groove part such that light emitted by the LED can be both transmitted directly from body unit and also reflected by the walls of groove part and then transmitted from body unit, wherein the main lead is configured to apply a driving voltage to the LED and the sub lead is configured to provide the driving voltage to an adjacent light source block, and wherein the main lead and the sub lead overlap the groove part in planar.
