A non-chip LED illumination device includes a retaining layer having one or more chambers for engaging with light emitting diode elements each of which include an outer surface and two terminals disposed on the outer surface of the light emitting diode element. A covering layer is engaged onto the retaining layer and the light emitting diode element and includes one or more openings aligned with the light emitting diode elements respectively. One or more fluorescent members of different colors are engaged into the openings of the covering layer for allowing the light generated by the light emitting diode elements to emit through the fluorescent members of different colors.
