The application of biometric recognition in LED emergency power supplies adds an extra layer of security and personalized control.

　　Biometric recognition technologies, such as fingerprint recognition, facial recognition, and iris recognition, can be used to access and control the LED emergency power supply. For example, in high - security areas like data centers or financial institutions, only authorized personnel with registered biometric data can access the emergency lighting system's settings or perform maintenance tasks. This ensures that the system is not tampered with by unauthorized individuals, maintaining its integrity and reliability during emergencies.

　　Fingerprint recognition is a widely used biometric technology in this context. It is relatively simple and cost - effective to implement. The LED emergency power supply can be equipped with a fingerprint sensor. When a user needs to access the system, they simply place their finger on the sensor. The sensor reads the unique fingerprint pattern and compares it with the pre - stored data in the system. If the match is successful, the user is granted access to the control functions of the emergency power supply.

　　Facial recognition technology offers a contactless and convenient way of access control. Cameras integrated with the LED emergency power supply can capture the facial features of a person approaching the system. The system then analyzes the facial data and verifies the identity of the user. This is especially useful in situations where quick access is required, such as during an emergency evacuation when users may not have the time to use other forms of identification.

　　In addition to access control, biometric recognition can also be used for personalized lighting settings. Different users can have their own preferred brightness levels, color temperatures, or lighting patterns for the LED emergency lights. The system can remember these settings based on the biometric identification of the user, providing a more customized and user - friendly experience.
