Light control switch composition based on mechanoluminescence

Abstract

The invention belongs to the technical field of sensor switches and discloses a light control switch composition based on a mechanoluminescence material. The light control switch composition is composed of mechanoluminescence composite materials, photoresistors and control circuits. The mechanoluminescence composite materials transmit light under the effect of dynamic external force. The photoresistors are connected with the control circuits through lead wires and receive the light of the mechanoluminescence, thereby resulting in resistance change. When changed resistance values reach reference values preset by the control circuits, switch functions are realized. The switches comprise embedded type and an un-embedded type. According to the embedded type light control switch, the photoresistor is directly embedded into the mechanoluminescence composite material. The photoresistor and the mechanoluminescence composite material of the un-embedded type light control switch are connected through a light guide medium. According to the light control switch composition, the light control switches are independent of a natural light source and a traditional artificial light source, the application market of the light control switches is expanded, and the light control switches have wide application prospect in aspects such as building environment safety monitoring, earthquake early warning and electromagnetic interference-free control circuits.

Description

technical field [0001] The invention belongs to the technical field of sensor switches, in particular to an optical control switch composition based on a stress luminescent material. Background technique [0002] The light control switch uses a photosensitive resistor. When the light changes, the resistance will change, so as to achieve various purposes by controlling the circuit. For the light-controlled switch of visible light, the circuit is controlled and adjusted by the brightness of visible light. It is generally used as a switch to control lights in streets, homes, dormitories, railways, stations, waterways, schools, power supply departments or other public places. The function of turning off the light at night to save electricity. For the light-controlled switch of infrared light, it is made by using the sensitivity of infrared sensor and photosensitive sensor to infrared light, so as to control the switch of the circuit, which can be applied to remote control, ligh...
