Abstract: A technique for forming a white light LED is disclosed. In one embodiment, the LED emits blue light. A first phosphor for producing red, yellow, yellow-green, or green light is formed to conformably coat the LED die. One suitable deposition technique is electrophoretic deposition (EPD). Over the resulting LED structure is deposited another phosphor (to add the remaining color component) in a binder (e.g., silicone) for encapsulating the die. The blue LED light combines with the two phosphor colors to create white light. Since the two different deposition techniques are independent and easily controllable, the resulting white light temperature is highly controllable and the color emission is substantially uniform.

Abstract: One or more LED dice are mounted on a support structure. The support structure may be a submount with the LED dice already electrically connected to leads on the submount. A mold has indentations in it corresponding to the positions of the LED dice on the support structure. The indentations are filled with a liquid optically transparent material, such as silicone, which when cured forms a lens material. The shape of the indentations will be the shape of the lens. The mold and the LED dice/support structure are brought together so that each LED die resides within the liquid silicone in an associated indentation. The mold is then heated to cure (harden) the silicone. The mold and the support structure are then separated, leaving a complete silicone lens over each LED die. This over molding process may be repeated with different molds to create concentric shells of lenses. Each concentric lens may have a different property, such as containing a phosphor, providing a special radiation pattern, having a different hardness value, or curable by a different technique (e.g., UV vs. heat).
