Description

Technical Field

[0001] The utility model belongs to the technical field of flash lighting, and in particular relates to a white light infrared two-in-one flash lighting optical system. Background Art

[0002] Flash lighting is used for monitoring fill light in smart traffic checkpoints, especially for monitoring cab personnel and face recognition during the day. Since the sunlight is very strong at noon during the day, a flash with high energy is needed for fill light. However, at night, since the environment is very dark, there is no need for particularly bright fill light. Therefore, infrared fill light with infrared filter is used at night to minimize light pollution. At present, the infrared white light in the industry generally uses high-power pulse xenon lamp plus infrared filter, but because the filter cannot be completely retracted, it will reduce the brightness of white light during the day, resulting in a large loss of white light. Perhaps 50% of the white light is lost during the day, which is not efficient. Utility Model Content
