Abstract
The present invention provides a light emitting device, including a base, an LED inversely mounted on the base. The LED includes a buffer layer, an LED chip on the buffer layer. The buffer layer includes a plurality of protrusions with complementary pyramid structure on a light-exiting surface of the LED. The present invention also provides a method for manufacturing a light emitting device, including: providing a substrate and forming a plurality of pyramid structures on the substrate; forming successively a buffer layer, an n-type semiconductor layer, an active layer, a p-type semiconductor layer and a contact layer on the substrate with the pyramid structures; forming an opening with a depth at least from the contact layer to a top of the n-type semiconductor layer, and forming a first electrode on the contact layer and a second electrode on a bottom of the opening; and removing the substrate. The light emitting device has a high luminous efficiency and the manufacturing method is easy to implement.
