TL;DR: In this paper, a method for a piezoelectric induction remote control LED lamp, which is used for achieving the method and a switch, has been described, which comprises the steps as follows: (1) an induction part arranged on the ground induces the pressure thereon and converts the pressure into an electric signal for outputting; (2) the electric signal supplies electricity to a circuit part which is connected with the induction part; (3) when the energy of electric signal is enough to enable the circuit part to normally work, the circuit parts transmits a wireless
Abstract: The invention discloses a method for a piezoelectric induction remote control LED lamp, the piezoelectric induction remote control LED lamp for achieving the method and a switch. The method comprises the steps as follows: (1) an induction part arranged on the ground induces the pressure thereon and converts the pressure into an electric signal for outputting; (2) the electric signal supplies electricity to a circuit part which is connected with the induction part; (3) when the energy of the electric signal is enough to enable the circuit part to normally work, the circuit part transmits a wireless control signal; and (4) the LED lamp receives the wireless control signal and controls the state according to the signal. By the technical scheme disclosed by the invention, a power circuit does not need to be arranged; a battery is also not required for supplying electricity; the pressure, on the lamp, from a pedestrian or a vehicle is directly converted into electric energy for supplying electricity; the power consumption in an off-working state is zero; meanwhile, the technical problem that an inductive sensor is in a working state for a long period of time and is easy to damage in the prior art is solved; energy conservation and environment protection are achieved; and the service lifetime of a product is also prolonged.
