Problems solved by technology

[0002] Iris recognition generally requires infrared light source supplementary light to assist in obtaining a clear iris image. The current infrared light source illumination range covers the entire field of view of the infrared camera, which consumes a lot of power, and the illumination intensity per unit area is low, and the supplementary light effect is poor.

Abstract

The invention discloses an infrared light source assembly. The infrared light source assembly comprises an infrared light source, a lens and a driving assembly, wherein the infrared light source is used for emitting infrared light, the lens covers the infrared light source and is used for leading the infrared light transmitted onto the lens outside the infrared light source assembly, and the driving assembly is used for driving the infrared light source and / or the lens to move to make the lens lead the infrared light to the target direction. For the infrared light source assembly, the infrared light source or / and the lens is driven through the driving assembly to move to make the infrared light emitted by the infrared light source to change through the emission direction after projection of the lens, the purpose that the infrared light is led by the lens to the target direction is realized, so the strong-enough infrared light can be projected to an eye portion of a to-be-identified object even when emission power of the infrared light source is relatively small, energy of infrared light beams of the infrared light source is made to be more concentrated, illumination intensity is relatively large, and the light supplement effect is relatively good. The invention discloses an electronic device.

Description

technical field [0001] The invention relates to the technical field of biological identification features, in particular to an infrared light source assembly and an electronic device. Background technique [0002] Iris recognition generally requires infrared light source supplementary light to assist in obtaining a clear iris image. The current infrared light source illumination range covers the entire field of view of the infrared camera, which consumes a lot of power, and the illumination intensity per unit area is low, and the supplementary light effect is poor. Contents of the invention [0003] Embodiments of the present invention provide an infrared light source assembly and an electronic device. [0004] The infrared light source assembly of the embodiment of the present invention includes: [0005] Infrared light source, the infrared light source is used to emit infrared light; [0006] a lens, the lens is arranged on the optical path of the infrared light source...
