In RFID multi-tag network, the image of the tag needs to be collected. Therefore, the research on the effect of LED array light source on the image capture of RFID tag is proposed. According to the optical properties of LED, the radiance illumination expression of LED array light source is deduced, and the illumination distribution of LED array is simulated. We choose the appropriate arrangement of array light sources and analyze the effect of the array on the collection of the tags. The research results show that the LED array design can effectively provide a uniform illumination of the light source. The design of LED array can obviously distinguish the tag from the background and improve the quality of the acquired RFID tag image.
