Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road lighting equipment, and particularly relates to a flexible installation type road photovoltaic lighting system. BACKGROUND

[0002] The road lighting generally adopts a system composed of a "lamp pole + LED lighting lamp + power supply", wherein the power supply includes two types of national grid alternating current power supply and solar power direct current power supply. The street lamp powered by the national grid is the most popular solution at present, and the street lamp powered by the solar power still cannot become the mainstream solution, and the reasons include the following:

[0003] (1) The existing solar street lamp adopts a distributed photovoltaic power supply mode, that is, one lamp pole is equipped with one set of independent solar power supply, and in order to avoid light blocking, the photovoltaic module is installed on the top of the lamp pole, which looks like a four-square hat on the lamp pole. In order to increase the beauty, decorations, design creative shapes or thin film photovoltaic modules, even colored photovoltaic modules are added, but the problem cannot be solved. The main reason is that people cannot abandon the structure of "photovoltaic module arranged on the top of the lamp pole", otherwise the solar power generation will be greatly affected.

[0004] (2) The length of the annual sunshine is unevenly distributed, and the average daily radiation in winter is half of that in summer. Therefore, the power supply configuration of the solar street lamp needs to consider the factor of low solar radiation in winter, so the capacity of the photovoltaic module needs to be increased, which means that the size of the photovoltaic module is increased. From the cost (in the era when the price of the photovoltaic module is relatively high) and the aesthetic point of view, the technical personnel generally choose to reduce the size (installed capacity) of the photovoltaic module, and reduce the power consumption through various power-saving means (for example: lower illumination, inductive lighting control strategy, night light-off, etc.) to achieve the purpose of balancing the supply and demand of electric energy. However, although these measures achieve energy saving, the lighting effect is weakened, and sometimes even violates the original intention of lighting, ultimately resulting in poor user experience and forming the folk image of "poor solar street lighting";

[0005] (3) The one-time investment cost of a single set of solar street lamp is generally higher than that of a single set of mains street lamp, and the main reason is that the solar street lamp needs to be equipped with a solar power system. At the same time, due to the fact that the solar power system is arranged on the top of the lamp pole, and the photovoltaic module and the energy storage battery of the solar power system are heavy, the mechanical strength of the lamp pole needs to be increased, especially the wall thickness needs to be increased, which significantly increases the cost of the solar street lamp.
