1. An ultraviolet light array module comprising:
a substrate having a concave formed on a top surface of the substrate;
multiple ultraviolet light (UV) chips arranged in a matrix in the concave of the substrate; and
an amorphous silicon concentrator disposed on the substrate, covering the concave, and including
a light-transmitting base covering the concave of the substrate and is kept a distance with the UV chips; and
multiple light-concentrating protrusions continuously formed integrally on the light-transmitting base in a matrix, and each light-concentrating protrusion corresponding to one of the UV chips and having an optical axis aligning with an emitting axis of the corresponding UV chip, wherein each ultraviolet light passing through the light-concentrating protrusions has a specific emitting angle and the ultraviolet lights passing through the light-concentrating protrusions overlapping to each other.
