Abstract

A lighting system and a projection device with enhanced functionality includes a light source in the lighting system for emitting first light, a first wavelength selection structure, and a second wavelength selection structure. The first wavelength selection structure includes a wavelength selection portion for transmitting the first light in a first target wavelength and a first light-transmitting portion for transmitting the first light. The light emitted then from the first wavelength selection structure is defined as second light. The second wavelength selection structure receives the second light and applies a supplementary portion for transmitting the second light in a second target wavelength and a second light-transmitting portion for transmitting the light. The light emitted from the second wavelength selection structure is adjustable as to colors, as to low or high color saturation, and as to low or high brightness of the projection image.
