    • A light emitting device includes a carrier, a light emitting element electrically connected to the carrier, a transparent plate having at least one through hole formed therein and including a flat-portion and a lens-portion and a permeable membrane structure disposed on a surface of the transparent plate. The lens-portion covers the light emitting element and has a light incident surface, a light emitting surface, a first and a second side surfaces. A first partial beam of the light beam passes through the light incident surface and leaves from the light emitting surface. A second partial beam of the light beam passes through the light incident surface and is transmitted to the first or the second side surface. The first or the second side surface reflects at least a part of the second partial beam of the light beam to be passed through the light emitting surface.
    • 发光装置包括载体,与载体电连接的发光元件,具有形成在其中的至少一个通孔的透明板,并且包括平坦部分和透镜部分和透液膜结构, 透明板。 透镜部分覆盖发光元件并且具有光入射表面,发光表面,第一和第二侧表面。 光束的第一部分光束通过光入射表面并从发光表面离开。 光束的第二部分光束通过光入射表面并被透射到第一或第二侧表面。 第一或第二侧表面反射待通过光发射表面的光束的第二部分光束的至少一部分。
