    摘要： An LED unit includes an LED and a lens mounted on the LED. The lens includes a light-incident face adjacent to the LED, a light-emergent face remote from the LED, and a light-reflecting face between the light-incident face and the light-emergent face. The light-incident face includes a first light-incident face facing the LED, and the light-emergent face includes a first light-emergent face located opposite to the first light-incident face. The first light-incident face is a continuously curved face which has a curvature, along a bottom-to-top direction of the lens, firstly decreasing gradually to a first value; then increasing gradually to a second value; then decreasing gradually again to a third value; and then increasing gradually again. The light-emergent face has a first light-emergent face located above the first light-incident face and having a varied curvature.

    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 face is aspherical. The outer face is spherical. The inner and outer faces are centrosymmetrical relative to axes, respectively, which are coincident with each other. A curvature of the inner face is gradually reduced from a center to an edge thereof.

    摘要： An LED module includes a housing, a plurality of LED modules, a plurality of first and second reflectors, a heat sink attached to the housing and an envelope engaged with the housing and covering the LED modules, the first and second reflectors. The housing includes a base and four sidewalls extending upwardly from edges of the base. The LED modules are mounted on the base. The first reflectors are accommodated in the housing and each cover a corresponding LED module. The second reflectors are mounted on the base and each located at a lateral side of the corresponding LED module.
