Abstract:
A light-emitting device may include at least one light source, which is configured for at least one of AC and PWM operation; and at least two optical buffers for absorbing light energy from the light source and for temporally delayed emission of the stored luminous energy, wherein the at least two optical buffers have different relaxation times and are sensitive to different wavelengths.
