LED DIE, METHOD FOR MANUFACTURING THE LED DIE AND AUTOMOBILE LAMP HAVING THE LED DIE

摘要

An LED die includes a transparent substrate, an N-type layer, an active layer and a P-type layer successively arranged on a first surface of the transparent substrate. A part of the N-type layer is exposed. The LED die further includes an electrode structure arranged on the P-type layer and the exposed surface of the N-type layer. A light outputting surface is formed on a second surface of the transparent substrate. The light outputting surface is a smoothly concave and arc-shaped surface. An LED automobile lamp with the LED die and a method for manufacturing the LED die are also provided. The light outputting surface of the LED die directly faces a lens of the LED automobile lamp.
