Abstract
The invention describes a semiconductor die comprising at least a first light-emitting diode and a second light-emitting diode, wherein the first light-emitting diode comprises a first diode formed in a first die area and a first phosphor layer deposited over the first die area; the second light-emitting diode comprises a second diode and a second phosphor layer deposited over the second die area; the first diode and the second diode are electrically connected in anti-parallel; and wherein the optical properties of the second phosphor layer differ from the optical properties of the first phosphor layer.
Claims15
A semiconductor die comprising:
- at least a first light-emitting diode, comprises a first diode formed in a first die area and a first phosphor layer deposited over the first die area;
