摘要： An LED lens and a light emitting device using the same are disclosed. The LED lens comprises a light incident surface, a light emitting surface, and a bottom surface. The light emitting surface includes a first recession portion disposed at the central thereof and a protrusion portion connected to the outer periphery of the emitting recession portion. The light incident surface comprises a first optically active area and a second optically active area. The first optically active area is disposed at the central of the light incident surface, and has a second recession portion; the second optically active area is a concave surface connected to the first optically active area. The LED lens satisfies specific conditions. The LED lens distributes a light beam emitted from the light emitting device to form an even light pattern.

摘要： The present disclosure discloses a light control lens and a light source device using the same. The light control lens comprises a light emitting surface, a light incident surface, and a total internal reflection (TIR) inclined surface. The light incident surface and the TIR inclined surface are at the opposite side of the light emitting surface. The TIR inclined surface is at the peripheral side of the light incident surface. Between the TIR inclined surface and a plane perpendicular to an optical axis of the light control lens, there is an included angle α of less than 45°. An effective radius of the light emitting surface is larger than the distance from an arbitrary point on the light emitting surface to a plane through an incident origin and perpendicular to the optical axis along the optical axis direction.
