Abstract
An LED module includes an LED and an elongated lens. The lens includes a center axis, a concave incident face, and an opposite convex emitting face. The emitting face includes a portion with a curvature radius at any point along a first plane larger than a distance between the point and the LED, and larger than a curvature radius at a corresponding point of the incident face on the first plane. A curvature radius at any point of the portion of the emitting face along a second plane perpendicularly intersected with the first plane at the center axis is larger than a distance between the point and the LED, while smaller than a curvature radius of a corresponding point at the incident face on the second plane. A radiating angle of the LED module in the first plane is larger than that in the second plane.
