摘要：
A luminescent light source including a blue light emitting diode (LED) chip, a red LED chip, and a wavelength converting material is provided. The blue LED chip and the red LED chip respectively emit a first light and a second light. A ratio of peak intensity of the second light to peak intensity of the first light ranges from 0.36 to 0.56. The wavelength converting material is disposed around the blue LED chip or the red LED chip and emits a third light. A wavelength of the third light ranges from a wavelength of the first light to a wavelength of the second light.
