Problems solved by technology

However, the current research on SCNN-based ceramics mainly improves the piezoelectric performance of ceramics through the substitution of Sr and Ca sites, and there are not many studies on the substitution of Nb and Na, which is not conducive to further promoting the research of SCNN-based lead-free piezoelectric ceramic systems.

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.

Description

technical field [0001] The invention relates to the field of piezoelectric induction control, in particular to a piezoelectric induction remote control LED lamp method, a piezoelectric induction remote control LED lamp and a piezoelectric induction remote control switch for realizing the method. Background technique [0002] LED lighting can be used in office buildings, residential buildings, stairs, elevator rooms, toilets, corridors, basements, car awnings and other places that require on-demand lighting. In these occasions, inductive lighting is generally only used when necessary (for example, when someone passes by or a car drives by). Sensors (infrared, microwave, sound, etc.) and LED lights are integrated. Inductive sensors such as infrared, microwave, and sound are all active sensors, and they must be in working condition all the time to play a monitoring role. This causes a waste of energy to a certain extent, and at the same time, the sensor is easily damaged if i...
