Abstract
A light indicator module is provided. The light indicator module includes a circuit board, a plurality of light sources, a light guide unit, and a shielding material. The light sources are disposed on the circuit board, and each light source provides a light beam. The light guide unit includes a plurality of guiding blocks. Each guiding block includes a light emitting surface, a light entering side surface, and at least one abuttal side surface. One of the light sources corresponds to the light entering side surface. The light beam enters the guiding block through the light entering side surface and is emitted through the light emitting surface. The abuttal side surface faces toward an adjacent guiding block. The shielding material covers the abuttal side surface.
