Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific examples, but the implementation of the present invention is not limited thereto.

[0023] Such as figure 1 Shown is the structural diagram of the power generating device in the present invention. The power generation device is made into a rectangular shape, which includes a plurality of kinetic energy capture mechanisms with the same structure and size, all of which are encapsulated in a fixed base, and are packaged and fixed with an intermediate cover plate, and the drive device It is a movable cover, and a plurality of permanent magnets are fixed below it for driving the capture mechanism. The movable cover is equipped with a positioning shaft, installed on the fixed base through the middle cover, and can move up and down. A spring is arranged on the positioning shaft of the movable cover to reset the movable cover.

[0024] Such as figure 2 The kinetic energy capture mechanism sho...

Abstract

The invention discloses a self-powered building stair lighting device comprising a generating set, a voltage regulation rectifying circuit, an energy storage device and an LED (Light Emitting Diode) lamp set which are installed on a step of a stair. When people walk through the stair and tread the above device, the device can absorb the pressure kinetic energy of a human body and convert the absorbed kinetic energy into electric energy; the generated electric energy is stored in the energy storage device by rectification and voltage regulation, the generated electric energy is utilized to drive low-power LED lamps distributed on the walls at the two sides of the stair, so that the lighting to the stair is realized. Compared with the existing stair emergency lighting technology, the self-powered building stair lighting device realizes the stair lighting without the access of an external power supply, and has the advantages of high reliability and good safety performance especially in the emergency condition, simultaneously the equipment input and maintenance cost of the stair emergency lighting are reduced, and further the economical input is reduced greatly.

Description

technical field [0001] The present invention relates to the field of renewable energy, in particular to a completely self-powered lighting device and method for building stairs that do not require external power supply, and in particular to a device and method for collecting kinetic energy of the human body and converting it into electrical energy. Background technique [0002] Along with the development of social economy, modernized cities have more and more high-rise buildings, and due to the popularization of elevators, these high-rise buildings are also generally installed with elevators for people to use. On the other hand, due to fire protection requirements, all buildings must have fire stairs, and be equipped with lighting, emergency lighting and other equipment. Since people generally do not use fire stairs, these lighting devices have been vacant for a long time, but they must be configured and maintained frequently, which is a very large expenditure. Considering...
