The invention discloses an interactive lighting terminal for security and protection of old people. The interactive lighting terminal can sense human body activities, detect the surrounding environment and interact with people. The interactive lighting terminal comprises a human body infrared sensing module, a machine vision module, a CO gas sensor, a smoke sensor, a voice recognition module, a single-chip microcomputer control module, a WiFi module, a relay module and a patch LED lamp strip. The sensor module is responsible for monitoring the activity state of old people and the indoor harmful gas concentration in real time. The single-chip microcomputer can process the collected real-time data, and judges whether the elderly falls down or not and whether the concentration of indoor harmful gas is harmful to the health or not. If the data processing result shows that the old people fall down, the indoor harmful gas concentration exceeds the standard or a fire disaster occurs, an alarm indicating lamp is triggered, alarm information is sent to a server through a WiFi module, the server pushes the information to a bound mobile phone, and the old people can be treated and cured in time conveniently. The voice interaction module can switch the lamp and switch the light effect according to the voice instruction of the user.
