Abstract

A total reflection lens (200), an optical projection system (10), and a projection optical engine. The total reflection lens (200) comprises a collimating portion (210) and a beam-expanding portion (220). In a direction from the collimating portion (210) to the beam-expanding portion (220), the cross-sectional dimension of the collimating portion (210) is increased. At the joint of the collimating portion (210) and the beam-expanding portion (220), the cross-sectional area of the total reflection lens (200) undergoes an abrupt change, and the cross-sectional area of the collimating portion (210) is greater than the cross-sectional area of the beam-expanding portion (220). Light emitted by a light-emitting light source (100) is collimated by the collimating portion (210) and then enters the beam-expanding portion (220) for beam expansion. The larger-sized beam-expanding portion (220) can receive light deflected at a smaller angle from the edges, thereby shaping both the deflected light and the collimated light together.
