Disclosed are a polarization LED module capable of reducing the size of a device by integrating a light source with a reflective planarization part and simplifying structure, and a lighting device and a projector having the same. The polarization LED module includes a casing which has an opening on a side; a light source which is arranged in the casing and generates light; a reflective planarization part which is arranged in the casing, transmits first polarized light included in light generated in the light source, induces it to an external planarization conversion part through the opening of the casing, reflects second polarized light, and induces it to the light source; and a reflection part which is arranged in the light source in the casing, reflects light which is reflected from the reflective planarization part and transmitted to the light source, to the reflective planarization part. |
