Abstract
A light emitting device is provided. The light emitting device includes a light emitting assembly having a first light emitting diode package structure and a second light emitting diode package structure. The light emitting assembly can generate a mixed light source having a spectral deviation index. The first light emitting diode package structure can generate a first light source having a first spectral deviation index. The second light emitting diode package structure can generate a second light source having a second spectral deviation index. When the first light source and the second light source are within a range from 460 to 500 nm, a sum of the first spectral deviation index and the second spectral deviation index is within a range from −0.3 to 0.3, and a difference between the first spectral deviation index and the second spectral deviation index is at least greater than 0.2.
