1. A lighting module, comprising:a light source module, which includes a light source plate and a plurality of Light-Emitting Diode (LED) light sources;
a driving module; andan optical element, wherein emergent light of the LED light source is emitted after passing through the optical element, and the optical element has a light incident portion and a light emergent portion;wherein the driving module and the LED light source are respectively adhered to the light source plate and are integrated on the light source plate, the light incident portion of the optical element covers above the light source plate, receives the emergent light of the LED light source and carries out optical configuration on the emergent light of the LED light source, and the driving module is arranged in a periphery of the light incident portion of the optical element;
wherein the optical element is a hybrid lens, and the light incident portion of the optical element includes a refraction region directly facing the LED light source and a total internal reflection region positioned on both sides of the refraction region and having at least two different heights relative to the refraction region, wherein the emergent light of the LED light source is refracted in the refraction region and then emitted from the light emergent portion, and the emergent light of the LED light source is totally reflected and then emitted after being refracted in the total internal reflection region, and the emergent light from different LED sources are overlapped after being refracted, wherein one LED source is situated substantially in a middle position of the optical element and another LED source is away from the one LED source and is situated in a distance from the one LED source; and
wherein an incident surface of the refraction region, which faces the LED light source, is a horizontal plane.
