  • Publication number: 20230056179
    Abstract: An electroluminescent device, wherein the electroluminescent device includes a first-conductivity-type semiconductor layer, a second-conductivity-type semiconductor layer, an active layer, a first electrode, a second electrode, and an optical conversion material. The active layer is disposed between the first-conductivity-type semiconductor layer and the second-conductivity-type semiconductor layer and electrically connected with these two. The first-conductivity-type semiconductor layer has a light-emitting surface disposed on a side opposite to the active layer, and includes a plurality of 3D structures arranged regularly, extending from the light-emitting surface towards the active layer to jointly define at least one cavity having a depth greater than 70% a thickness of the first-conductivity-type semiconductor layer. The optical conversion material is filled in the cavity.

  • Publication number: 20200201087
    Abstract: An optical control element for a light beam to pass through and including a transparent substrate and a plurality of reflective structures is provided. The transparent substrate has a light-entering surface and a light-emitting surface opposite to each other. The reflective structures are disposed in the transparent substrate. Each of the reflective structures has a bottom surface adjacent to the light-entering surface and a side surface connected to the bottom surface. A width of each reflective structure in a direction of a horizontal view angle is gradually decreased from one end adjacent to the light-entering surface to one end away from the light-entering surface. The bottom surface and the side surface respectively reflect parts of the light beam, and in a direction vertical to the bottom surface, transmission directions of the light beam reflected by the bottom surface and that reflected by the side surface are opposite to each other.
