Abstract
A reflection module of a car lamp includes a shell, and a reflection mechanism in the shell; the reflection module includes a main part, a first reflection portion sticking from the main part, a separating plate connected to an upper edge of the first reflection portion, a second reflection portion sticking upwards from an edge of the separating plate, and a blocking plate positioned on the separating plate in an adjustable manner; each of the separating plate and the blocking plate has a slot thereon, and the slots together define a light passage; therefore, the width of the light passage can be adjusted such that light from a shining element will be reflected outside from the reflection module with an upper edge of the light beams being in a horizontal direction to define an imaginary horizontal line called the cut-off, and light from the lamp won't be dazzling.
