Beschreibung
Zusammenfassung:	A white light illumination system including a first light emitting chip, a second light emitting chip and a wavelength conversion unit is provided. The first light emitting chip is capable of emitting a first light. The second light emitting chip is capable of emitting a second light. Wavelength of the second light is different from that of the first light. The wavelength conversion unit is disposed on the first light emitting chip and the second light emitting chip. The second light is converted into an excited beam when irradiating on the wavelength conversion unit. The excited beam includes a second red light. In addition, the excited beam, the first light, and the second light are mixed to produce a white light with color temperature substantially approximate to 3000K.
