LED traffic light structure

A traffic light structure includes an LED light source having a circuit board and multiple LEDs securely mounted on the circuit board, a front cover having a first incidence surface provided with multiple lenses each with rectangular lenses and a first emergence surface and an inner cover sandwiched between the front cover and the LED light source and having a second incidence surface and a second emergence surface provided with columns symmetrically arranged relative to a central axis on the second emergence surface. Light of the LEDs scattered and reflected by the inner cover and the front cover is inclined downward to a horizontal axis of the front cover.
