In the 20th century, major energy sources such as oil, coal, and natural gas were in danger of depletion of resources. Especially since the outbreak of the worldwide oil crisis in 1973, the energy crisis has sounded the alarm. At the same time, the pressure of environmental protection is increasing, making environmental protection and energy conservation a trend of research, utilization and development in all walks of life. As the truly inexhaustible clean energy on the earth, solar energy is the most ideal green energy source. An effective way to utilize it is to use photovoltaic power generation technology to convert solar energy into electrical energy. LED (lightemitting diode) is a semiconductor device that can convert electrical energy into visible light. It has been used in lighting fields in many industries because of its energy-saving and pollution-free characteristics. Therefore, as a solar LED lighting system that integrates the advantages of solar photovoltaic power generation and LED solid lighting, it is the perfect combination of a new generation of energy and a new generation of light sources.
The use of solar LED technology has become one of the important research projects in the world for new energy sources and new energy conservation and environmental protection. In 1996, the United Nations held the World Solar Summit in Zimbabwe. After the meeting, it published important documents such as the Harare Solar and Sustainable Development Declaration, the International Solar Convention, and the World Solar Strategic Plan, further demonstrating the United Nations and the world. The firm determination to develop solar energy requires global action and extensive use of solar energy.
At present, the solar energy utilization technology and the semiconductor lighting industry have entered the commercialization stage from the technological development stage. The development of new energy sources and the full and rational use of existing energy sources have been greatly valued by governments. The solar LEDs that integrate the new generation of energy and the new generation of light sources have seen an unprecedented rate of development. In China, the application of solar water heaters has become very popular, and street lighting, traffic instructions, night lighting, and garden decoration have also been promoted and applied in many cities. The comprehensive utilization of solar energy has the basic conditions for popularization and application. Taking the 2008 Beijing Olympic Games as an opportunity, the concept of a green Olympics was proposed in due course. Many Olympic venues are using solar LEDs, and energy conservation and environmental protection have made a model from design to comprehensive utilization. For example, the first floor of China's solar energy is located not far from the Beijing Olympic Park. The energy consumption in the building and the courtyard is all self-sufficient by the solar energy system, including air conditioning system, power supply system, heating system and hot water supply system. The proposal of the Green Olympics and the comprehensive utilization of solar energy not only gave the Olympic Games the concept of promoting energy conservation and environmental protection, but also far-reaching significance is to promote the promotion of green energy such as solar energy.
With the widespread use of solar LEDs, from the concept to the promotion and application, governments around China have attached great importance to them and have given great attention and encouragement policies. In 2007, the Fujian Provincial Government officially forwarded the “Implementation Opinions on Promoting the Development of LED Solar Photovoltaic Industry in Fujian Province†(2007-2010) to further clarify the development goals and priorities, policies and measures for the LED solar photovoltaic power generation industry in Fujian Province. This year, Yangzhou City, Jiangsu Province issued a support policy for supporting LED solar photovoltaic power generation industry, encouraging all types of personnel to set up LED solar photovoltaic enterprises and encouraging all types of capital to enter the industry. Support the world's top 500 companies and multinational companies to set up a regional headquarters or R&D center for LED solar photovoltaic power generation in Yangzhou. Enterprises that apply for the LED solar photovoltaic power generation industry shall be subject to barrier-free registration, and shall be registered on the spot with complete declaration materials and legal forms, and the business licenses shall be issued on the spot. The limited liability company and the registered capital of the company limited by shares can be set up in phases. The initial capital contribution is not less than 20% of the registered capital, and the rest is paid within two years from the establishment of the company. At the same time, the restrictions on the registered capital of enterprises are relaxed. The monetary assets such as proprietary technology and intangible assets can be invested as the capital. The maximum amount of capital contribution can account for 70% of the total registered capital.
The introduction of such policies and regulations has led us to see the local government's emphasis on LED solar photovoltaic power generation industry and its firm confidence in development and utilization. The government level, industry application level and consumption level are gradually improved. Everyone has the awareness of energy conservation and environmental protection, and actively participates in the environmental protection and energy conservation business. We firmly believe that solar LED applications will be rapidly popularized and lead us into a new green energy conservation. era.

It has long-strip shape, and it is mainly used for decorative lighting of building or outline of huge buildings. With a large number of models, it has many advantages such as bright and luminous efficiency, energy saving, rich in color, bright and beautiful patterns, high light efficiency, long working life as long as 50,000 hours, resistant to high temperature and low temperature, non-pollution, etc.. The Wall Washer Light includes seven-color wall washer light, full-color wall washer light and multi-color wall washer light. Its power capability determines the distance of its projection, and it is mainly divided into different levels of 18W, 24W, 36W and 48W, etc.. The power can be changed flexibly according to the requirements. It can be controlled by microchip to achieve many dynamic effects such as gradual change, hopping change, color flashing, random flashing and alternating gradual change.It is widely used in commercial properties, hotels, exterior walls of buildings, squares, staircase lightposts, parks, roads, garden trees, ancient buildings and so on. In recent years, LED Wall Washer Light is commonly used in lighting project.
