Abstract
A light-emitting diode (LED) lighting device includes a substrate, an isolation layer, a first bottom electrode, a second bottom electrode, at least one first vertical LED, a first conductive bonding layer, at least one second vertical LED, a second conductive bonding layer, a first transparent sealing material, a second transparent sealing material, and a top electrode. The substrate has a base portion and a plurality of protruding portions present on the base portion. The base portion and the protruding portions cooperate to define at least one first recess and at least one second recess. At least one of the first recess and the second recess has a bottom surface and at least one sidewall adjacent to the bottom surface. The bottom surface and the sidewall are reflective. The first vertical LED and the second vertical LED are electrically connected in series.
