摘要： An LED module includes an LED having an optic axis and a lens fixed over the LED for refracting light emitted by the LED. The lens has a same cross section along a front-to-rear direction thereof. The lens has an inner incidence surface facing the LED and an outer emission surface. The inner incidence surface is concave toward the emission surface. The emission surface has a middle part around the optic axis of the LED concave toward the incidence surface, and two convex lateral parts off the optic axis of the LED. A peak intensity for the light generated by the LED and penetrating through the lens occurs within the convex lateral parts of the emission surface.

摘要： An LED module includes an LED and a lens fixed with the LED for refracting light emitted by the LED. The lens has a center axis and a concaved inner face for incidence of the light and an opposite convex outer face for the light refracting out thereof.

摘要： An LED unit includes an LED and an envelope receiving the LED therein. The envelope includes a bottom substrate fixing the LED thereon, a sidewall angling upwardly from the substrate and surrounding the LED, and a lens formed in the sidewall and located above the LED. The lens has two aspheric surfaces with different curvatures to collect light deflected at a small angle relative to an axis of the LED into a parallel pattern. The sidewall has upper and lower conical inner circumferences and a parabolic outer circumference to direct light deflected at a large angle relative to the axis of the LED into parallel pattern. The lower inner circumference of the sidewall has an angle of 2π/5 to 13π/30, and the upper inner circumference of the sidewall has an angle of 5π/36 to 7π/36.

摘要： An LED module includes an LED having a central axis I, and a lens. The lens has an incident face for incidence of the light of the LED and an opposite emitting face for refracting the light of the LED out of the lens. The emitting face of the lens has a central axis II. The central axis II is offset from the central axis I and located at one side of a plane ZOX of an XYZ coordinate with an original O which is located at a center of the LED, in which the central axis I is coincident with the Z axis. The light beams emitted from the one side of the plane ZOX are stronger than the light beams emitted from the another side of the plane ZOX after the light beams emitted from the LED pass through the lens.
