M248185

The present invention relates to a kind of lighting device, especially a lighting device using solar cell and storage battery self-sufficient power. …… Energy cold cathode lamp_ [Previous technology] # Generally, the action principle is to use the intrusion of various measuring elements to determine whether to pass sound or light. The type = two signals, to achieve the purpose of anti-theft and deterrence, only Known and non-contact design, in which contact is like vibration sensing, while non-contact is like infrared sensor. Infrared is used in anti-theft system. It can be divided into active two infrared (the sensor itself will emit an infrared beam to detect the movement of the object), and dynamic infrared PIR (the sensor itself does not emit an infrared beam, but depends on the heat source of the object Motion trigger sensor). Traditional anti-theft alarm devices generally do not have the function of lighting. Most of them issue warnings with strong sounds, but in the approved Taiwan Patent Bulletin No. 3 1 6701, a combination of Lightning and infrared human body sensing device in short power failure. In short, this is a design that integrates the automatic start-up mechanism and emergency lighting device by measuring the human body with infrared debt. In addition to retaining the function of automatically starting the lighting during a power failure, it can also When a moving object is detected, the battery provided in the emergency lighting device is used to provide the electrical energy required for lighting. In this known technology, a photoresistor for detecting the environmental conditions is also designed to match the environment. Brightness changes to improve the lighting function in a timely manner. 〃
