Zusammenfassung:Provided are a light board, a method for manufacturing the same, a light-emitting diode (LED) backlight module and an LED backlight device. The light board includes a substrate and a LED device. The substrate includes a first surface and a second surface disposed opposite to each other. The first surface and the second surface are each provided with a wiring area and a non-wiring area. A first heat sink assembly and multiple first reinforcement ribs are disposed in the non-wiring area of the first surface. The multiple first reinforcement ribs intersect to form a first encircled area. The first heat sink assembly is disposed in the first encircled area. The LED device is disposed in the wiring area of the second surface.
