Abstract

The invention provides an invisible information collection lighting device. An infrared light source is provided through LED infrared surface-mount lamps. The color background of invisible information is removed. A tapered casing reflects infrared light emitted by each LED infrared surface-mount lamp at an inclined reflection angle. The phenomenon of non-uniform light of a cylindrical totally closed structure in the prior art is avoided. The problem of low quality of subsequent collected images is avoided.

Description

technical field [0001] The invention relates to the technical field of invisible information collection, in particular to a lighting device for invisible information collection. Background technique [0002] At present, most of the handheld devices used for scanning codes are aimed at standard code systems such as barcodes or two-dimensional codes, and the corresponding lights are mostly white and red; with the enhancement of anti-counterfeiting security awareness and the development of printing technology, in In the food, cosmetics and other industries, more and more companies have begun to use invisible information (such as dot matrix codes) to make anti-counterfeiting marks, and the materials are also varied. Therefore, the use of light in special wavebands such as infrared and ultraviolet is gradually increasing, and the shapes of light source devices (strips or domes) are also varied. [0003] In practical applications, when companies use dot matrix codes to make anti-...
