Zusammenfassung:The invention discloses an LED landing lamp module and a landing lamp optical system. The LED landing lamp module is composed of a TIR lens and an LED light source. The TIR lens is a rotationally symmetrical body having a bowl-shaped structure. The bottom surface of the TIR lens is provided with a pit part which is recessed upwards. And the top surface of the pit part is configured to be a convex surface which is convex downwards. And the inner circumferential surface of the pit part is a refracting surface of the lens. And the peripheral surface of the TIR lens is a total reflection surface of the lens. And the top surface of the TIR lens is a light-emitting surface of the lens. The top surface of the TIR lens is formed with four light ridges arranged in a matrix. And the light edge directions of the two light edge parts in the same row are opposite. And the light edge directions of the two light edge parts in the same row are the same. And the LED light source is arranged at the bottom of the pit part. The
