摘要： An LED unit includes a printed circuit board, an LED mounted on the printed circuit board, and a lens covering the LED and fixed on the printed circuit board. The lens includes a pedestal and an optical element connected to the pedestal. The lens has a light-incident face formed in an interior thereof for receiving light emitted from the LED into the lens, and a light-emergent face formed on an outside thereof for refracting the light out of the lens. The optical element has two opposite sides longer than the other two opposite sides thereof so that the light pattern modulated by the optical element has two opposite ends wider than a middle thereof.

摘要： An LED unit includes an LED and a lens receiving the LED. The lens includes a first light-incident face confronting the LED to refract the light emitted from the LED with a small angle into the lens, a second light-incident face surrounding the LED to refract the light emitted from the LED with a large angle into the lens, a light-reflecting face to reflect the light from the second light-incident face towards a top of the LED, a first light-emergent face to refract the light from the first light-incident face out of the lens, and a second light-emergent face to refract the light from the light-reflecting face out of the lens.

摘要： A lens includes a light incident surface and a light exiting surface. The light exiting surface includes a first curved surface, a first convex surface, a second convex surface, a second curved surface, and a third curved surface. The first curved surface is located at the center of the light exiting surface. The first and second convex surfaces are arranged at two opposite sides of the first curved surface respectively for converging the light exiting therefrom, the first convex surface, the first curved surface, and the second convex surface connect in sequence along a first direction. The first and third curved surface are arranged at another two opposite sides of the first curved surface respectively; the second curved surface, the first curved surface, and the third curved surface connect in sequence along a second direction substantially perpendicular to the first direction.
