US Patent:

20160165692, Jun 9, 2016

Filed:

Dec 5, 2014

Appl. No.:

14/562639

Inventors:

- Livermore CA, US
Jesus DEL CASTILLO - Livermore CA, US

International Classification:

H05B 33/08
H05B 37/02

Abstract:

A lighting module includes a light emitting diode (LED) array and a dimming circuit configured to control current applied to the LED array to control luminance of light emitted from the lighting module.

Appl. No.:

15/008358

Inventors:

- Livermore CA, US
Jesus Del Castillo - Palo Alto CA, US

International Classification:

H05B 33/08
H01L 33/62
H01L 33/50

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.
