Abstract: Provided is an optical module. The optical module includes a substrate; a light emitting diode provided on the substrate; a first member that is provided in front of the substrate, transmits some of the light emitted from the light emitting diode and reflects some other light; and a second member that is provided between the substrate and the first member so as to be spaced apart from the first member at a predetermined interval, is formed with an exposed region by which the light emitting diode is exposed at a position corresponding to the light emitting diode, and re-reflects the light reflected by the first member forward again.
