Abstract
A direct emitting LED illumination module for eliminating chromatic dispersion improves a vehicular LED lamp to comply with related regulations. The LED illumination module includes a LED light source and a plano-convex lens. The LED light source is located at the focus of the plano-convex lens. The LED light source emits light to the plane of the plano-convex lens, and the light exits from the convex surface of the plano-convex lens. The plano-convex lens focuses the light to form a desirable light pattern. Besides, the plane of the plano-convex lens has a microstructure thereon to suppress the angular correlated color temperature deviation of the light pattern and eliminate chromatic dispersion.
