| description | The invention relates to the technical field of night vision security and protection, in particular to a red exposure elimination method and an infrared supplement lamp using the same. According to the method, an infrared lamp source is subjected to beam expanding, then a compound eye lens is used for expanding the output aperture of infrared lamplight obtained after beam expanding, uniform lightspots are formed, and then the red exposure phenomenon is eliminated. The infrared light supplement lamp comprises the infrared lamp source, a collimating lens and a compound eye optical assembly which are all located on the same straight line. The infrared lamp source is used as an infrared illumination light source and emits an infrared light beam; the collimating lens is used for converting thelight beam emitted by the infrared lamp source into a collimating wide light beam parallel to the optical axis of the collimating lens; and the compound eye optical assembly is used for dividing thecollimated wide light beam |
