A light-emitting device with at least two light-emitting dies encapsulated with two different types of the wavelength-converting materials is disclosed. Each of the wavelength-converting materials is configured to produce a visible light from a narrow band light near UV region produced by the light-emitting dies, but with different correlated color temperatures (CCT) and different spectral contents. The combination of the two visible light forms the desired visible white light. The Color rendering index of the light-emitting device is tunable by adjusting the supply current to the light-emitting dies. In another embodiment, a light module with tunable CRI for an illumination system is disclosed.

Light source with tunable CRI

A package for a light source, a semiconductor device, and methods of manufacturing the same are disclosed. In particular, a Light Emitting Diode (LED) dice is attached to a bonding pad of the light source package by two discrete types of different adhesives. One of the adhesives may be curable under exposure to Ultraviolet (UV) light and the other adhesive may be cured under thermal radiation, but is stable when exposed to UV light.
