The invention discloses an infrared lighting projector. The projector adopts infrared laser to irradiate an up-conversion material in order to generate three primary colors, and the three primary colors are taken to be a lighting source. The infrared lighting projector is composed of a light source module, a lighting module, a projector slide module, a projection optical module, a color measurement module and a circuit control module, wherein infrared semiconductor laser modules and up-conversion sheets in the light source module form arrays, and conversion from infrared to red light, green light and blue light is achieved; the lighting module homogenizes light of the three colors; the projector slide module is used for initially displaying images to be projected; the projection optical module images the images displayed on the projector slide module to a projection screen; the color measurement module conducts color measurement on the homogenized light output by the lighting module; the circuit control module conducts automatic color correction. The infrared lighting projector has the advantages of being wide in display color domain, long in service life and low in cost and automatic in color correction.
