Abstract: A color tunable lighting module is described which includes at least three solid state lighting emitters (such as light emitting diodes) and at least two wavelength converting elements (such as phosphors). The three solid state lighting emitters are formed of the same semiconductor material system and the light generated by them has dominant wavelengths in the blue-green-orange range of the optical spectrum. The two wavelengths converters are used re-emit some of the light from two of the emitters in broader spectra having longer dominant wavelengths, while the third emitter is selected to emit light at a wavelength between the dominant wavelengths of the light from the two emitters and the two converters. A control system may be employed to monitor and control the module and the lighting module can be optimized for tunable high color quality white light applications.

Abstract: A tunable color LED module comprises at least two sub-modules, each comprising an LED, a wavelength converting element (WCE) and a reflector cup. The total light emitted by the module comprises light generated from each LED and WCE and the module is configured to emit a total light having a predefined color chromaticity when activation properties of the LEDs are managed appropriately. The total light may have a broad white emission spectrum. The module combines the benefits of a low cost with uniform chromaticity properties in the far field, and offers long and controlled lifetime at the same time as flexibility and intelligence of tunable color chromaticity, Color Rendering Index (CRI) and intensity, either at manufacture or in an end user lighting application. A controlled LED module system comprises a control system for the managing activation properties of the LEDs in the sub-modules. Also described is a method of manufacture.
