The times are developing and progressing, and all aspects of our lives are changing. The original trolleys are gradually replaced by motorcycles, electric cars, and automobiles. The changes in our lives are not only that, it can be said that there are countless, and today we will detail the changes in outdoor lighting.

　　Outdoor lighting is understood from the surface meaning to be lighting activities other than home. In ancient times, lighting at night was mainly lighting and direct staying. People's activities were generally during the day and travel less at night. With the delay of time, the emergence of electricity has led to street lights. This lighting method can basically satisfy people's night activities. This is the history of outdoor lighting development.

　　Speaking of outdoor lighting, we have to talk about the changes in light sources. From the initial bulbs and sodium lamps to today’s LED light sources, the overall efficacy and lifespan have reached a qualitative improvement. It can be said that the emergence of LED light sources has driven the lighting industry throughout the day. Development, in just a few years, there are countless derivative products led by it.

　　Outdoor lighting has been using two renewable resources, photovoltaic power generation and wind power generation, in recent years. On the one hand, it is a policy support factor, and on the other hand, market competition has promoted the transformation and upgrading of the industry. The solar street lights that have been seen everywhere in recent years are just a microcosm of the development of outdoor lighting.

　　With LED light sources and photovoltaic panels, two energy storage devices are indispensable. In the early years, solar street lights used colloidal batteries, which need to be buried in the ground. Poor packaging of this battery or external damage will make the street light not bright. In addition, this kind of battery Buried in the ground for a long time will pollute the land. The many disadvantages of colloidal batteries have led to the gradual elimination of this product. The emergence of lithium batteries has become a good substitute for it. Due to the small size, large energy storage, and convenient installation of lithium batteries, the new solar street lights installed in the past few years have been Use lithium batteries as a solution.

　　Nowadays, outdoor lighting is moving closer to environmentally friendly new energy sources. Floodlights, garden lights, lawn lights, and landscape lights have all changed to adopt photovoltaic lighting solutions, which are energy-saving and environmentally friendly, easy to install and free of wiring, and adhere to the green, healthy and sustainable development. Road will be the impetus for product updates and iterations in the next ten years or even longer.
