发明名称 METHOD OF ADJUSTING THE LIGHT-EMISSION OF A LIGHT EMITTING DIODE AT A GIVEN DRIVING CURRENT
摘要 A method is disclosed of adjusting the light-emission of a light-emitting diode to a predetermined output level for a given driving current. The light-emitting diode is irradiated with a laser beam in a manner to burn tiny holes in the light-emitting surface to such an extent that said predetermined output level is obtained. The invention furthermore comprises a method of obtaining a substantially uniform light output of an array of light-emitting diodes.
