Title:
INTELLIGENT LONG-DISTANCE INFRARED FILL-LIGHT SET
Document Type and Number:
WIPO Patent Application WO/2021/143787
Kind Code:
A1
Abstract:
An intelligent long-distance infrared fill-light set for illuminating a predetermined target range at least 500 meters away cooperates with an infrared image-acquisition equipment (6) to obtain an image of an illuminated-object (501, 511, 511'), and includes: infrared fill-lights each including an optical lens (11), optical axis (111) passing through a focus (112), infrared light sources (2, 2') emitting an infrared beam (21, 21') having a main beam angle (0), to generate a substantial overlapping area (211, 211') and at least one non-overlapping area (212, 212') when illuminating to the predetermined target range (51, 51'); enabling devices (3) that enable light sources (2, 2'); and a control unit (4) receiving image data acquired by the infrared image-acquisition equipment (6), for calculating and adjusting the enabling device (3) to locally strengthen or weaken the substantial overlapping area (211, 211') and/or non-overlapping area (212, 212'). Infrared fill-lights are spaced a predetermined distance, so that the human eyes (8) accidentally entering a predetermined dangerous illumination range (D) will not be simultaneously illuminated by infrared beams (21, 21'), thereby avoiding exceeding a Maximum Permissible Exposure (MPE).
