Abstract
A light-emitting device is provided. comprises: a light-emitting stack comprising an active layer emitting a first light having a first peak wavelength λ nm; and an adjusting element stacked on and electrically connected to the active layer, wherein the adjusting element comprises a diode emitting a second light having a second peak wavelength between 800 nm and 1900 nm; wherein a forward voltage of the light-emitting device is between (1240/0.8λ) volt and (1240/0.5λ) volt, and a ratio of the intensity of the first light emitted from the active layer at the first peak wavelength to the intensity of the second light emitted from the diode at the second peak wavelength is greater than 10 and not greater than 1000.
