用聚光灯以识别。
当你打开了所有的灯闪烁徽章控制在一定的频率，产生足够的光噪声战胜面部识别系统的设备。
When you turn on a device controlled by the badge all the lights blink at a certain frequency that generates enough optical noise to defeat facial recognition systems.
本发明提供了一种内置式宽角度LED补光灯，涉及智能交通系统中车牌识别技术领域。
The invention provides a built-in wide-angle LED light-compensating lamp which relates to the technical field of license plate recognition in an intelligent traffic system.
本发明的效果是在扩大前照灯照射范围的同时，凭借汽车行进方向的照明提高识别力，提高夜间驾驶的安全性。
Effect of the invention lies in enhancing judgment by means of automobile steering lighting while expanding scope of the head light irradiation, and enhancing security while drive at night.
手指静脉识别仪包括近红外线LED灯和黑白相机传感器。 近红外LED灯发出近红外射线，当近红外射线穿透手指时，手指静脉的血红蛋白将吸收近红外光，因此，图像中静脉将变为黑色。
Each unit houses a near-infrared (NIR) LED and monochrome CCD camera sensor, so as the red pigment in blood (hemoglobin) absorbs NIR light, veins appear as dark lines on the resulting image.
