1. A lighting apparatus, comprising:
a driver for converting an external power to generate multiple driving currents;
a light source comprising a package holder integrating multiple LED modules having different output light parameters, the package holder having multiple terminals for separately receiving the driving currents to control the multiple LED modules independently in the package holder, wherein the package holder has a plastic housing for disposing the terminals, for holding the multiple LED modules and for filling a fluorescent layer covering the multiple LED modules; and
a controller for controlling the driver for adjusting a relative ratio among the multiple driving currents to render an output light of the light source corresponding to predetermined optimized settings for at least an object illuminated by the light source, wherein the multiple LED modules respectively comprise different fluorescent layers to render the different output light parameters, wherein a surface of the multiple fluorescent layers forms a convex lens surface for changing light paths of the light source to a condensed light beam, wherein the multiple fluorescent layers are attached to a lens first as a module and then the module is disposed above LED chips of the multiple LED modules.
