Infrared-ray radiating lamp for automobile

In an infrared imaging system for a motor vehicle having a lamp for irradiating a region in front of the vehicle with radiation including infrared radiation, a least one imaging camera for sensing radiation returned from said region, and a display for displaying information derived from said at least one imaging camera, the improvement wherein:

• said lamp comprises a light source simultaneously emitting infrared and visible light onto said region via an infrared-ray transmitting film that transmits said infrared light and has at least one aperture which emits said visible light,
• wherein said infrared light is of an intensity sufficient to operate said imaging camera, and said visible light is of a color and intensity sufficient to substantially mask a visible red component accompanying said infrared light.
