摘要： A light emitting device includes a substrate, light emitting units, an insulation layer, a current distribution layer and a reflective layer. The substrate has an upper surface. The light emitting units are disposed on the upper surface and include at least one first light emitting diode (LED) and at least one second LED. A first side wall of the first LED is adjacent to a second side wall of the second LED so as to define a concave portion exposing a portion of the upper surface. The insulation layer at least covers the first side wall and the second side wall. The current distribution layer covers the concave portion and at least covers a portion of the second LED. The reflective layer covers the current distribution layer and is electrically connected to the first LED and the second LED.

摘要： An electrode pad structure of a light emitting device includes an insulation layer, a first type electrode pad and at least one second type electrode pad. The light emitting device has a centerline and the light emitting device is divided into two equal blocks via the centerline. The first type electrode pad is disposed on the insulation layer and symmetrical to the centerline. The second type electrode pad is disposed on the insulation layer and symmetrical to the centerline. The first type electrode pad is coplanar with the second type electrode pad, and a portion of the insulation layer is exposed between the first type electrode pad and the second type electrode pad.

摘要： A light-emitting device including a substrate, a light emitting structure and a coarse structure is provided. The substrate has an upper surface and a lower surface opposite to each other, and an annular side surface connecting the upper surface and the lower surface. The light emitting structure is disposed on the upper surface of the substrate. The coarse structure is formed on the annular side surface of the substrate. A ratio of a thickness of the substrate and a thickness of the coarse structure is greater than or equal to 1 and less than or equal to 20. Therefore, the overall light-emitting efficiency of the light-emitting device may be improved.
