Embodiment Construction

[0068] According to the different ways of use, functions and working power of road lamps, the piezoelectric power generation system that provides energy can be installed in different ways such as whole road pavement, partial pavement and discrete piezoelectric device installation. The following are combined with several examples. To illustrate.

[0069] see Figure 1~6 , according to the technical solution of the present invention, the first embodiment takes an urban street street lamp system as an example to further illustrate the arrangement and implementation of the system. Since the use of street lamps is characterized by time-segmented lighting, and the power required to be provided during the lighting period is relatively large (more than 50kW per kilometer of lane), it is suitable to use a piezoelectric power generation system paved across the road. The system structure of this example is as follows figure 2 As shown, the whole street lighting system is composed of p...

Abstract

This invention discloses a piezoelectric generation method by using road surface vibration energy, which lays piezoelectric devices inside the road or uses them as the as the road components directly and utilizes the vibration energy to generate electric energy provided to road lamps or other road installations or energy storage devices and electric nets. The system includes: a piezoelectric device a power transforming energy generated by the piezoelectric devices to be stored in an energy storage devices, road lamps or an energy storage device, said piezoelectric device is connected with the transforming device, which is connected with lamps and energy storage device.

Description

technical field [0001] The invention relates to a road lamp and a system thereof utilizing the vibration energy of the road surface, in particular to a piezoelectric power generation method and a road lamp system utilizing the vibration energy of the road surface. Background technique [0002] At present, street lamps, signal lamps and other road administration facilities used in all parts of the world, including mainland China, generally use AC grid or DC grid to provide energy. There are big deficiencies that cannot be overcome. First of all, in today’s increasingly scarce energy, electric energy is quite precious. The existing road power grid is dominated by medium and low-voltage power grids, and the power loss of long-distance low-voltage power grids is astonishing; secondly, many remote mountainous areas or suburban road power grids are not covered Wherever you go, the road lamps and other road facilities that play a vital role in driving safety cannot be laid, instal...
