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.

Abstract: An indicator module is provided, including a device housing, a circuit board, a plurality of light sources, a dividing structure, and a homogenizing plate. The device housing includes a transparent window. The circuit board is disposed in the device housing. The light sources are disposed on the circuit board, wherein each light source is adapted to provide a light beam. The dividing structure is disposed in the device housing, wherein the dividing structure defines a plurality of divided spaces, and the divided spaces respectively correspond to the light sources. The homogenizing plate is disposed in the device housing. The homogenizing plate corresponds to the divided spaces, wherein an air gap is formed between the transparent window and the homogenizing plate. The light beam enters the divided space from the light source, passes through the homogenizing plate and the air gap, and is emitted through the transparent window.
