Automobile lamp lighting device, automobile lamp assembly and automobile

A vehicle lamp illuminating apparatus, comprising a lens (1), a circuit board (4), a plurality of light emitting diode (LED) light sources (3) disposed on the circuit board (4) and distributed in an array, and a reflection structure (2) disposed between the plurality of LED light sources (3) and the lens (1), wherein the plurality of LED light sources (3) distributed in an array are transversely arranged in an upper row and a lower row, the reflection structure (2) comprises a plurality of reflection mirror sets each disposed in one-to-one correspondence with two LED light sources (3) that are vertically opposite to each other, the reflection mirror set comprises a first level reflection mirror (20) located between the two LED light sources (3) that are vertically opposite to each other, and a second level upper reflection mirror (21) and a second level lower reflection mirror (22) that are respectively disposed above and below the first level reflection mirror (20) at an interval in an opposite manner;

• and light emitted by the LED light source (3) in the upper row is incident into the lens (1) after being reflected first by the first level reflection mirror (20) and then by the second level upper reflection mirror (21), and light emitted by the LED light source (3) in the lower row is incident into the lens (1) after being reflected first by the first level reflection mirror (20) and then by the second level lower reflection mirror (22).
