Abstract
Disclosed is a white light emitting diode module including a conducting wire frame, a first primary color chip, a second primary color chip and a phosphor layer. The conducting wire frame has an accommodating groove. The first primary color chip is installed at the bottom of the middle of the accommodating groove, and the first primary color chip transmits a first light emitting source with a wavelength λ. The second primary color chip is stacked on top of the first primary color chip and the second primary color chip transmits a second light emitting source with a wavelength λ. The phosphor layer is formed on the second primary color chip and excited to produce a fluorescent light with a wavelength λ. Therefore, the stacked LED chips and the phosphor can be used to obtain a white light source with high color saturation.
