LIGHTING APPARATUS SYSTEM USING ENERGY SCAVENGING

摘要

The present invention provides a lighting device system using energy acquisition including an energy obtaining device using RFID and a lighting device operating according to a control signal transmitted from the energy obtaining device using RFID, wherein the energy obtaining device using RFID includes: An energy converter converting surrounding energy into electrical energy through energy acquisition, a control signal generator configured to receive a user input and generate a control signal of a lighting device based on the electrical energy; And a control signal transmitter for transmitting to a lighting device, wherein the energy converter comprises a piezoelectric converter for converting the user input into the electrical energy using a piezoelectric element, and a light energy converter for converting light energy into the electrical energy. And a control unit for generating the control signal. And receiving the user input corresponding to the ruler to generate the control signal, wherein the light energy converter obtains the electrical energy while the control signal transmitter does not transmit the control signal. It is about. According to the present invention, it is possible to operate without a separate power source through energy acquisition, and generate control signals for a plurality of lighting devices. For example, when using a wired power source, inconvenience such as checking and replacing a battery level when using a wire or a portable power source can be eliminated. It can also improve the environmental problems of replacing batteries. In addition, since a plurality of lighting devices can be controlled by using an energy acquisition device using one RFID, a disadvantage of designating a switch for each lighting device can be improved.
