Abstract: Blue component light emitted from blue LEDs is reflected to a Fresnel lens at a reflecting member having a parabolic cross-section. The fluorescent material is added substantially uniformly in the Fresnel lens. Part of the blue component light is transmitted through the Fresnel lens while another part of blue component light undergoes wavelength conversion at the Fresnel lens. By the wavelength conversion, the fluorescent material in the Fresnel lens is excited by the blue component light and the fluorescent light thus excited emits light containing a yellow color component. The yellow component light resulting from the wavelength conversion is projected via the Fresnel lens as uniform light with the blue component light.
