    摘要: An LED module includes a printed circuit board, an LED mounted on the printed circuit board, and a lens fixed on the printed circuit board and covering the LED for refracting light emitted by the LED. The lens has a concaved inner face for incidence of the light and an opposite convex outer face for the light refracting out thereof. The inner and outer faces are both spherical. A curvature of the inner face is smaller than that of the outer face.
