Stair step illumination device with self power generation capability

Abstract

The invention provides a stair step illumination device with self power generation capability. The stair step illumination device with the self power generation capability comprises a power generator and a lighting circuit, wherein the power generator is assembled on a stair step and used for converting pressure, which is applied to a piezoelectric ceramic by stepping the step, into electrical energy based on a piezoelectric effect; the illumination device is used for directly utilizing the electrical energy for illumination or storing the electrical energy. The stair step illumination device has the following beneficial effects that: the pressure applied to the step when a pedestrian walks on a stair is utilized to generate electricity and the electricity is supplied to the illumination device arranged in the stair. The stair step illumination device is simple, low in cost, convenient to install, capable of being produced in a standardization manner, free from external power supply and free from dependence on the external power supply; the reliability of illumination under an emergency in the stair is increased and the safety is enhanced.

Description

technical field [0001] The invention relates to the field of energy conversion, in particular to a stair step self-generating lighting device which utilizes lead-free piezoelectric ceramics as the core component of energy conversion and generates electric energy through the piezoelectric effect. Background technique [0002] At present, lighting equipment in buildings mostly relies on external power sources. Due to the large number of buildings and the high utilization rate of stairs, the lighting equipment in the stairs consumes a lot of energy. In addition, when the external power supply fails and the power supply is stopped, the lighting equipment in the stairs stops working, and there is no fixed lighting when people pass, which poses safety hazards. [0003] Piezoelectric ceramics can convert mechanical energy into electrical energy through the direct piezoelectric effect, and convert electrical energy into mechanical energy through the inverse piezoelectric effect. At...
