PURPOSE: An infrared lighting apparatus is provided to adjust the light emitting angle of an infrared light source according to a change of necessary illumination or a distance to a place to be recorded by an infrared CCD camera, thereby realizing efficient recording. CONSTITUTION: A penetration hole is formed on the center of a base plate(200). A slide rod(210) is installed in at least three spaces along with the external circumference of the base plate. A ball screw axis(310) is installed in a ball screw shaft housing(300) installed in the center of the base plate. A moving plate(400) moves forward/backward by the rotation of the ball screw shaft. A light source plate(500) is combined with the moving plate by at least two fixing rods(520). |
