LED reflector for improved light extraction

   
   

Light emitting diodes are provided with electrode and pad structures which redirect light which otherwise would be blocked by the pad. The LED may be formed as a die with first and second contact surfaces. A pad is in contact with the first contact surface. A reflector is disposed beneath the first pad, and the reflector includes walls that are oblique with respect to the first contact surface.

Os diodos emitindo-se claros são fornecidos com as estruturas do elétrodo e da almofada que dirigem de novo a luz que seria obstruída de outra maneira pela almofada. O diodo emissor de luz pode ser dado forma como um dado com primeiramente e em segundo superfícies de contato. Uma almofada está no contato com a primeira superfície de contato. Um refletor é disposto abaixo da primeira almofada, e o refletor inclui as paredes que são oblique com respeito à primeira superfície de contato.
