摘要： A wavelength conversion module that includes a reflective substrate, a strip-shaped wavelength conversion layer, and a microstructure layer is provided. The strip-shaped wavelength conversion layer is located on the reflective substrate and includes a transparent base and a wavelength conversion material doped in the transparent base. The microstructure layer is located on the strip-shaped wavelength conversion layer and includes a plurality of microstructures. The microstructures are arranged on a surface of the microstructure layer in a close-packing manner. The wavelength conversion module satisfies n2−0.3≦n1≦n2+0.3, where n1 is a refractive index of the transparent base, and n2 is a refractive index of the microstructure layer. An illumination system is also provided.

摘要： The present invention provides an optical lens device, comprising a LED module and an optical lens. The structure of the optical lens is symmetrically formed with respect to a central axis, the structure comprising a funnel-like upper face, a base face and a lateral face. At the center of base face, there is projectingly provided with a light-guiding structure. Rays emitted from the LED module are allowed to enter into the optical lens through the light-guiding structure, and a part of wide-angle rays are totally reflected by a lateral side of the light-guiding structure to be directed toward the upper face, and then emitted through the lateral face after totally reflected by the upper face. Accordingly, the side illuminating rays may be increased by directing the part of wide-angle rays to be emitted through the lateral face, and thus the luminous efficacy of side illumination is enhanced.
