The invention discloses a refraction, reflection and total reflection condensing lens. The condensing lens comprises an optically denser medium, an optically thinner medium and a reflecting surface, and is characterized in that: the optically thinner medium and the optically denser medium form a light incidence region; the optically denser medium and the optically thinner medium form a refractioncondensing light region; the reflecting surface forms a reflecting region; the optically denser medium and the optically thinner medium form a total reflection condensing light region; the refraction, reflection and total reflection condensing lens is divided into three layers and one surface; the three layers comprise a central layer, an intermediate layer and an outer layer; the central layer is formed by the optically denser medium; the cross sectional area of the central layer decreases from top to bottom; the intermediate layer is formed by the optically thinner medium; the outer layer is formed by the optically denser medium; the one surface is the reflecting surface outside the three layers; the upper surface of the refraction, reflection and total reflection condensing lens is a light incident face, and the lower surface of the refraction, reflection and total reflection condensing lens is a light emergent face; and the lens has the main energy loss characteristic that a part of energy is lost when a part of light passes through the reflecting surface.
