An LED module includes an LED and a lens located over and enclosing the LED. The lens includes a surface of incidence facing the LED for an incidence of light emitted from the LED and a surface of emission for an emission of the light out of the LED module. The surface of incidence has a convex spherical surface, and the surface of emission has a concave spherical surface corresponding to the convex spherical surface. The convex spherical surface refracts the light incident thereon to redirect the light to the concave spherical surface. The concave spherical surface spreads the light into a wide and uniform beam. The surface of emission further has a first cylinder extending downwardly from an outer edge of the concave spherical surface. A totally reflective coincoid extends downwards from the first cylinder to a bottom of the LED module.
