Abstract:
A lighting device includes a monolithic LED chip flip-chip mounted onto an interconnect structure. The monolithic chip includes LED junctions formed from a single LED junction. An active electronic component is also mounted onto the interconnect structure at a distance from the monolithic chip that is less than five times the maximum dimension of the monolithic chip. The active electronic component controls LED drive currents independently supplied to the LED junctions. Different types of phosphor are disposed laterally above the various LED junctions. A color sensor measures the light emitted from the lighting device when drive currents are supplied to first and second LED junctions. The active electronic component then supplies more drive current to the first LED junction than to the second LED junction in response to the color sensor measuring the light emitted when the prior LED drive currents are supplied to the first and second LED junctions.
