Abstract: An illuminating module includes two spaced-apart light sources, two hemispherical reflectors, two parabolic reflectors and two planar reflectors. Each of the light sources is disposed at a common focal point of one of the hemispherical reflectors and one of the parabolic reflectors. Each of the parabolic reflectors faces a respective one of the hemispherical reflectors in one direction, and confronts a respective one of the planar reflectors in the other direction such that light rays from each of the light sources which radiate toward the respective hemispherical reflector and the respective parabolic reflector are directed to the respective planar reflector so as to be subsequently reflected to travel in parallel lines parallel to an optical axis.
